News that Microsoft made a $44.6 billion bid to buy Yahoo resulted in heated discussions made by many Internet users. Here are some responses:
Diane Burke of Weeks bury, Kentucky
I think it would definitely be an interesting combination. Everyone recognizes the names Yahoo and Microsoft, but everyone also says, “Did you Google it?” Such a catchphrase (时髦话) is going to be hard to beat.
Shaun Carney of Laurelville, Ohio
I think the merger (合并) will provide more competitions for Google. I don’t think the merger will allow Microsoft to develop faster than Google, though. I believe the increased competition this merger brings will force Google to stay on top of its game by offering more fresh and original Internet tools and expanding on the tools it already offers.
Toni Suarez of Hacienda Heights, California
I view the merger as a necessary element in preventing a monopolization (垄断). Perhaps it would bring better high technology innovations to e-mail and help in researching and developing a better Internet!
Rick R. of Edgewater, Florida
It sounds like a disaster to me. If this were to happen, I would stop using my Yahoo e-mail account because I don’t like the feeling of Microsoft spying upon my business. I will sign up for Google.
Antonio Glosser of Kansas City, Missouri
Right now, Yahoo offers a lot of features and tools at no cost for all different levels of Internet users. Microsoft seeks nothing but profit. Undoubtedly, they’ll do nothing other than find ways to start removing Yahoo’s formerly non-priced features. Microsoft’s greed will ruin the great thing that Yahoo currently is.How many companies are mentioned in the passage?
| A．One. | B．Two. | C．Three. | D．Four. |
Which of the following statements is NOT true according to the passage?
| A．Shaun’s attitude towards Google is passive. |
| B．Toni believes the Internet will have a promising future. |
| C．Rick will support Google after the merger. |
| D．Antonio is afraid that the merger will cost Yahoo’s free features. |
The passage is mainly about ______.
| A．the future of Yahoo and Microsoft |
| B．the strengths of Yahoo and Microsoft |
| C．the strengths and weaknesses of large companies |
| D．opinions on the merger of Yahoo and Microsoft. |
London Underground
The world’s first subway was built in London in 1863. At the time，the government was looking for a way to reduce traffic problems in the city of London. The poor areas of the city were so crowded with people that it was almost impossible for horse carriages to get through. The city officials were interested in trying to make it possible for workers to live outside of London and travel easily to work each day. If people had a cheap and convenient way that they could depend on to go to and from work， they would relocate their homes outside of the city. This would help ease(减轻) the pressure of too many people living in the poor parts of London. From these problems，the idea of the London Underground，the first subway system，was born.
The plans for building the Underground met with several problems and delays，but the fast track was finally opened in January 1863. A steam train pulled the cars along the fast underground track which was 6 kilometers (3.7 miles) long. About 30，000 people got on the subway the first day. Riders were treated to comfortable seats (standing up while the train was moving was not allowed)， and pleasant decorations inside each of the cars. However， the smoke from the engine soon filled the air in the tunnels with ash and soot(煤灰)， as well as chemical gases. Fans had to be put in the tunnels later to keep the air clean enough for people to breathe. Even with its problems，riding in the Underground did catch on. It carried 9 million riders in its first year.What led the British government to build the London Underground？
| A．Traffic jams and pollution. |
| B．Population and pollution. |
| C．Overcrowding and traffic jams. |
| D．The poverty and subway problems. |
How did the London Underground solve the smoke problem？
| A．It made the tunnels larger. |
| B．It put fans in the tunnels. |
| C．It cleaned the chemical gases in the tunnels. |
| D．It reduced the number of passengers riding in the train. |
The underlined phrase “catch on” most probably means “______”.
| A．be troublesome | B．become popular and fashionable |
| C．keep up with | D．seize |
Which of the following is TRUE？
| A．To relocate the workers’ homes outside London，the government built the subway. |
| B．There were so many problems and delays that in 18th century the first subway opened. |
| C．The subway greatly eased the pressure of traffic. |
| D．There were not enough seats for the passengers the first day the subway opened. |
Petroleum, consisting of crude oil（原油） and natural gas, seems to originate from organic matter in marine sediment（海洋沉淀物）.Tiny organisms settle to the seafloor and gather in marine mud. The organic matter may partially break down, using up the dissolved oxygen in the sediment. As soon as the oxygen is gone, decay stops and the remaining organic matter is preserved.
Continued sedimentation buries the organic matter and subjects it to higher temperatures and pressures, which change the organic matter to oil and gas. As muddy sediments are pressed together, the gas and small drops of oil may be squeezed out of the mud and may move into sandy layers nearby. Over millions of years, accumulations of gas and oil can collect in the sandy layers. Both oil and gas are less dense than water, so they generally tend to rise upward through rock and sediment.
Oil pools are valuable underground accumulations of oil, and oil fields are regions underlain by one or more oil pools. When an oil pool or field is discovered, wells are drilled into the ground. When the well reaches a pool, oil usually rises up the well because of its density difference（密度差） with water beneath it or because of the pressure of expanding gas trapped above it. Although this rise of oil is almost always carefully controlled today, strong natural flows of oil were common in the past. Gas pressure gradually dies out, and oil is pumped from the well. Water or steam may be pumped down neighboring wells to help push the oil out.
As oil becomes increasingly difficult to find, the search for it is extended into more unfriendly environments. The development of the oil field on the North Slope of Alaska and the construction of the Alaska pipeline are examples of the great expense and difficulty involved in new oil discoveries. Offshore drilling platforms extend the search for oil to the ocean’s continental shelves. More than one-quarter of the world’s oil and almost one-fifth of the world’s natural gas come from offshore, even though offshore drilling is six to seven times more expensive than drilling on land.
Of course, there is far more oil underground than can be recovered. Even given the best exploration techniques, only about 30 to 40 percent of the oil in a given pool can be brought to the surface. The rest is far too difficult to reach and has to remain underground.Which of the following is true about petroleum formation?
| A．Microscopic organisms that live in mud produce crude oil and natural gas. |
| B．Large amounts of oxygen are needed for petroleum formation to begin. |
| C．Petroleum is formed when organic material in sediments combines with decaying organisms. |
| D．Petroleum formation appears to begin in marine sediments where organic matter exists. |
What does the development of the Alaskan oil field mentioned illustrate?
| A．More petroleum is extracted from the sea than from land. |
| B．Drilling for oil requires huge financial investments. |
| C．The global demand for oil has been increasing over the years. |
| D．The North Slope of Alaska has substantial amounts of oil. |
What does the author mainly intend to tell us in the passage?
| A．The formation, processing and exploration of petroleum |
| B．The specific techniques involved in oil exploration. |
| C．The changing relationships between countries. |
| D．The future intense situation in oil product markets. |
What can we infer from the passage?
| A．Available exploration techniques serve our purpose of exploring oil very well. |
| B．More and more public regions will be further protected from being drilled in the future. |
| C．Countries may suffer from unpleasant relationships for respective benefits in exploring oil. |
| D．Powerful flows of oil is a phenomenon which can be witnessed rarely now. |
The City of Christchurch, New Zealand was struck by a 7.1magnitude earthquake on the early morning of Saturday, September 4, 2010.
No tsunami alert was reported. The country's army troops were on standby to assist victims and disaster recovery operation. New Zealand's Prime Minister John Key, flew to the affected area to inspect and assess the situation of the damaged city. The Prime Minister said that the full assessment of the damages would possibly take months to know the severity of damages. Based from his assessment on what he saw in the area, it could cost at least 2 billion New Zealand dollars or US$1.4 billion for reconstruction.
“An absolute miracle that no one died，” Prime Minister John Key said. Two were seriously injured from this quake and thousands of local residents were awakened after being shaken at 4：35 a.m. of that Saturday.
There were people trapped inside the damaged buildings but fortunately none were reported dead from the rubble of the damaged buildings.
“We're all feeling scared—we've just had some significant aftershocks，” a survivor told TV One News. “Tonight we're just people in the face of a massive natural disaster, trying to help each other and we're grateful we haven't lost a life.”
GNS Science reported 29 aftershocks within the 14 hours after the quake, with strength from magnitude 3.7 to 5.4.
New_Zealand_is_no_stranger_to_earthquakes. The country experiences more than 14，000 earthquakes a year—but only about 150 are felt by people.
“Many buildings here were built with earthquake protection measure. However, in most cities in developing countries, people build how they want to and there're no building controls to force them to build to a higher standard that's safe，” Andrew Charleson, an architecture professor at Victoria University of Wellington told CNN.How many people were killed in the New Zealand earthquake on September 4, 2010?
| A．250，000. | B．29. | C．2. | D．0. |
After the earthquake, all of the following occurred EXCEPT that________．
| A．a number of aftershocks broke out |
| B．army troops were there to help |
| C．no people were injured or killed |
| D．the full assessment of the damages can't take in a short time |
What does the writer want to say by quoting Professor Andrew Charleson's words in the last paragraph?
| A．Earthquakes are much more terrible and bigger in developing countries. |
| B．Lacking of money, developing countries can't build safe buildings. |
| C．Building controls are the guarantee of safe buildings. |
| D．In developing countries, people have more freedom to design their buildings the way they like. |
What does the underlined sentence mean?
| A．Earthquakes break out frequently in New Zealand. |
| B．The earthquakes breaking out in New Zealand are very strange. |
| C．The earthquakes breaking out in New Zealand are unusual. |
| D．Earthquakes rarely hit New Zealand. |
What's the main idea of the passage?
| A．A massive earthquake struck the city of Christchurch of New Zealand. |
| B．No one was ever killed in earthquakes in New Zealand. |
| C．New Zealand has strict laws to guarantee the buildings' safety. |
| D．A miracle happened in the terrible earthquake. |
It’s illegal for the police to attach a GPS unit to your car without your permission, as the U.S. Supreme Court settled in 2012．But if the police are in hot pursuit of a bank robber or other escaping criminals that threaten public safety, a GPS tracker is acceptable. But exactly how can the police GPS track a car that is moving fast?
The answer to that question comes from StarChase，a new police technology being used by a small but growing number of law enforcement agencies．It allows the police to fire 4．5-inch glue-covered GPS bullet-like projectiles(发射体)from an air gun fixed in their police cars．If the GPS tracker makes contact with the escaping robber’s car， it’ll stick no matter how fast the vehicle is going．That way, the police will have a constant read on the car’s location and heading．Aside from simply apprehending(逮捕)criminals，it's believed this new technology could help save lives．If the police successfully fire a GPS unit at a speeding criminal，they can pull back from a high-risk chase．Chases can be incredibly dangerous to all involved，including innocent bystanders and other drivers．Once the GPS bullet connects，there's no need for the chase any longer．
Now，predictably,a GPS-loaded gun isn’t cheap. Police departments need to pay about $5．000 per vehicle for the technology,and individual GPS bullets cost as much as $250 each．That may sound expensive，but remember：The alternative is often thousands of dollars in property damage，and great human cost in injury and lost life．According to Star Chase，their GPS bullet system has an apprehension rate of 80％without any report of inury or property damage．If you’d like to learn more about the StarChase system，Popular Mechanics has just published a good article about it．There’s also plenty more information available at the company’s website．When the GPS bullet sticks to the escaping robber’s car，the police can________
| A．know the car’s condition |
| B．ensure the robber’s safety |
| C．play a fair game with the robber |
| D．know the car’s position and direction |
The GPS bullets could help save lives mainly because________．
| A．the bullets won’t hurt people |
| B．they can make the robber’s car stop |
| C．the police can stop the dangerous chasing |
| D．they have more advantages than normal bullets |
From the text we can learn that GPS bullets__________．
| A．are useful for the police |
| B．are widely used in America |
| C．can control the rising crime rate |
| D．can replace the police in the future |
In which part of a newspaper can we read the text?

This is VOA. The National Cryptologic Museum is on Fort George G. Meade, a military base near Washington, DC. The method of hiding exact meanings is called coding. People have used secret codes throughout history to protect important information. The National Cryptologic Museum celebrated 60 years of cryptologic excellence in 2012. One event there marked the sixtieth anniversary of the National Security Agency. Two former NSA workers shared their memories of operating a code machine called Sigaba.
In 1940, an American woman named Genevieve Grotjan found some information being repeated in Japanese coded messages. Her discovery helped the United States understand secret Japanese diplomatic messages. After the United States understood the code, it was possible to study messages from the Japanese ambassador to Germany and to his supervisors in Japan.
Understanding these messages helped the United States prepare for a possible war in the Pacific with Japan. After the attack on Pearl Harbor, an American Naval officer named Joseph Rochefort struggled to understand the Japanese navy code. He worked on the American base at Pearl Harbor. It was early in 1942. The American naval commander in the Pacific Ocean was Chester Nimitz. His forces were much smaller than the Japanese Naval forces. And the Japanese had been winning many victories. Joseph Rochefort had worked for several months to read the secret Japanese Naval code called JN-25. If he could understand enough of the code, he would be able to give Admiral Nimitz very valuable information.
From the beginning of 1942, the Japanese code discussed a place called "AF." Joseph Rochefort felt the Japanese were planning an important battle aimed at "AF." After several weeks, he and other naval experts told Admiral Nimitz that their best idea was that the "AF" in the Japanese code was the American-held island of Midway. Admiral Nimitz said he must have more information to prepare for such an attack.
The Navy experts decided to trick Japan. They told the American military force on Midway to broadcast a false message. The message would say the island was having problems with its water-processing equipment. The message asked that fresh water be sent to the island immediately. This message was not sent in code.
Several days later, a Japanese radio broadcast in the JN-25 code said that "AF" had little water. Joseph Rochefort had the evidence he needed. "AF" was now known to be the island of Midway. He also told Admiral Nimitz the Japanese would attack Midway on June 13.The battle that followed was a huge American victory. That victory was possible because Joseph Rochefort learned to read enough of the Japanese code to discover the meaning of the letters "AF."
One American code has never been broken. Perhaps it never will. It was used in the Pacific during World War Two. For many years the government would not discuss this secret code. Listen for a moment to this very unusual code. Then you may understand why the Japanese military forces were never able to understand any of it.
The code is in the voice of a Native American. The man you just heard is singing a simple song in the Navajo language. Very few people outside the Navajo nation are able to speak any of their very difficult language.
At the beginning of World War Two, the United States Marine Corps asked members of the Navajo tribe to train as Code Talkers.
The Cryptologic Museum says the Marine Corps Code Talkers could take a sentence in English and change it into their language in about 20 seconds. A code machine needed about 30 minutes to do the same work.
The Navajo Code Talkers took part in every battle the Marines entered in the Pacific during World War Two. The Japanese were very skilled at breaking codes. But they were never able to understand any of what they called "The Marine Code."
The Cryptologic Museum has many pieces of mechanical and electric equipment used to change words into code. It also has almost as many examples of machines used to try to change code back into useful words.The NSA was founded__________.
| A．in 1940 | B．1942 | C．in 1952 | D．in 2012 |

| D．The US Marine Corps was fallen for in Midway Islands battle |
The Americans used the Navajo language in their coding system during the Second World War for the reason that .
| A． unusual language was successfully used for codes |
| B．it was commonly used in coding system worldwide |
| C．the United States Marine Corps invented it then |
| D．it was the most beautiful language in the world |
This passage is probably adapted from ____________.

LONDON, Aug. 19 (Xinhua) -- A four-year-old child’s ability to draw could be an indicator of intelligence at age 14, according to a study published on Tuesday in the British journal Psychological Science.
The researchers from King’s College London (KCL) studied 7,752 pairs of identical and non-identical twins, and found that the link between drawing and later intelligence was influenced by genes.
At the age of 4, children were asked by their parents to complete a ‘Draw-a-Child’ test. Their drawings were rated from 0 to 12, based on the presence and correct number of body-parts, like arms, legs, head, eyes and nose.
The children were also given verbal and non-verbal intelligence tests at ages 4 and 14. According to researchers, the test was devised in the 1920’s to assess children’s intelligence, so it’s not surprising that the test correlated with intelligence at age 4.However, they found that higher scores on the test were also moderately associated with higher scores of intelligence at 14.
The researchers also measured the heritability of figure drawing. Identical twins share all their genes, whereas non-identical twins only share about 50 percent. Overall, at age 4, drawings from identical twin pairs were more similar to one another than drawings from non-identical twin pairs.
Therefore, the researchers concluded that differences in children’s drawings have an important genetic link. They also found that drawing at age 4 and intelligence at age 14 had a strong genetic link.
“Drawing is an ancient behaviour, dating back beyond 15,000 years ago,” Dr. Rosalind Arden, lead author of the paper from KCL, said that: “This capacity to reproduce figures is a uniquely human ability and a sign of cognitive ability, in a similar way to writing, which transformed the human species’ ability to store information, and build a civilisation.”According to the passage, which of the following statement about ‘Draw-a-Child’ test is true?
| A．The test was devised in the 1920’s. |
| B．7,752 identical and non-identical twins took part in it. |
| C．The test was set to assess children’s intelligence. |
| D．The children took the test at four. |
Which of the following words is closest in meaning to the underlined word “devised” in the 4th paragraph?
| A．changed | B．formed | C．taken | D．designed |
What do we know about the twins from the passage?
| A．Those who could draw better at 4 tend to be more intelligent at 14. |
| B．Twins who look similar to each other draw better pictures. |
| C．They were chosen to take the drawing test by the researchers. |
| D．They were tested on how smart they were once. |
From the last paragraph, we can infer that ___________.
| A．human society develops because of the ability to draw figures |
| B．drawing helps improve humans’ ability to study |
| C．one’s intelligence is related to his ability to draw pictures |
| D．only human beings are able to draw pictures |
Gunman Adam Lanza shot and killed 20 children in two classes of Grade One in Sandy Hook Elementary School. The only survivor(幸存者) is a six-year-old girl. She escaped by lying on the floor pretending to be killed.
After the accident , she ran out of the school building covered from head to feet with blood (血). The first thing she said to her mother was, “ Mommy, I was OK, but all my friends were dead,” Pasrtor(牧师) Jim Solomon told the ABC news’s Lara Spencer this weekend , “I thought it was impossible for her to escape from being killed without others’ help. She could behave so calmly in such a dangerous and frightening situation. She has wisdom beyond her age, for sure.”
The girl, whose name is not being written out for special reasons, was the first student to run out of the accident place at Sandy Hook, Solomon said. He said the young girl described the gunman to her mother in a way that only a young child could. “Well, she saw someone who she felt was angry, and someone who she felt was mad,” Solomon said. “Somehow, at that moment, thank God, she was able to act as if she were already dead and saved herself. And that is very unusual and admirable (令人钦佩的) for so young a girl.” she said.
There were 20 students killed on Friday in Sandy Hook Elementary School, eight boys and 12 girls. Six teachers were also killed. “Her parents told me that they couldn’t stand the feeling of a survivor’s guilt（ 负罪）, because so many of their friends no longer have their children but they have theirs.” Solomon said.
“I think you can understand their feelings as well,” he said how the girl’s mother and father were feeling about the disaster. “I don’t know whether I would have the kind of feeling that they have if the same thing happened to me.”How did the six-year-old girl escape from being killed?
| A．By fighting against the killer |
| B．By pretending to be killed |
| C．By running away quickly |
| D．By getting protection from teachers |
According to the passage, which word can best show the quality of the girl?
| A．Strong | B．Friendly |
| C．Wise | D．Curious |
From the passage, we can know that___________________.
| A．all students in Sandy Hook were killed |
| B．Solomon didn’t remember the name of the girl |
| C．eight other children escaped the accident |
| D．people didn’t know the six-year-old girl’s name |
Why did the girl’s parents feel guilty?
| A．Because they had some relationship with the gunman. |
| B．Because they didn’t tell the skills of escaping to other children. |
| C．Because their daughter survived while their friends didn’t. |
| D．Because they didn’t report the terrible accident ahead of time. |

Now, the VOA Special English program WORDS AND THEIR STORIES.
People use their mouths for many things. They eat, talk, shout and sing. They smile and they kiss. In the English language, there are many expressions using the word mouth. But some of them are not so nice.
For example, if you say bad things about a person, the person might protest and say “Do not bad mouth me.”
Sometimes, people say something to a friend or a family member that they later regret because it hurts that person’s feelings. Or they tell the person something they were not supposed to tell. The speaker might say: “I really put my foot in my mouth this time.” If this should happen, the speaker might feel down in the mouth. In other words, he might feel sad for saying the wrong thing.
Another situation is when someone falsely claims another person said something. The other person might protest: “I did not say that. Do not put words in my mouth.”
Information is often spread through word of mouth. This is general communication between people, like friends talking to each other. “How did you hear about that new movie?” someone might ask. “Oh, by word of mouth.” A more official way of getting information is through a company or government mouthpiece. This is an official spokesperson. Government-run media could also be called a mouthpiece.
Sometimes when one person is speaking, he says the same thing that his friend was going to say. When this happens, the friend might say: “You took the words right out of my mouth!” Sometimes a person has a bad or unpleasant experience with another person. He might say that experience “left a bad taste in my mouth.” Or the person might have had a very frightening experience, like being chased by an angry dog. He might say: “I had my heart in my mouth.”
Some people have lots of money because they were born into a very rich family. There is an expression for this, too. You might say such a person, “was born with a silver spoon in his mouth.” This rich person is the opposite of a person who lives from hand to mouth. This person is very poor and only has enough money for the most important things in life, like food.
Parents might sometimes withhold sweet food from a child as a form of punishment for saying bad things. For example, if a child says things she should not say to her parents, she might be described as a mouthy child. The parents might even tell the child to stop mouthing off.
But enough of all this talk. I have been running my mouth long enough.Which of the following can best describe his or her feeling if a speaker feels down in the mouth?
| A．Delighted | B．Regretful |
| C．Disappointed | D．Respectful |
When your car was close to knocking into a truck, you might say “_______”
| A．I really put my foot in my mouth this time. |
| B．I had my heart in my mouth. |
| C．I live from hand to mouth. |
| D．I get to know it by word of mouth. |
According to the passage, which behavior is surely Not welcome?
a. bad mouthing somebody
b. mouthing off about something
c. putting words in somebody’s mouth
d. taking the words right out of somebody’s mouth
| A．abc | B．abd | C．bcd | D．acd |
What do “I” probably (in the last Para.) do?
| A．A host | B．A journalist |

A group of Russian criminals have stolen l.2 billion username and password combinations for more than 500 millione-mail addresses. It's the largest known theft on the Internet, according to a report of The New York Times.
Cyber security firm Hold Security discovered the security breach(漏洞 ). The firm found that the group of criminals collected personal information from 420,000 websites, including household names and small Internet sites. The criminals were based in a small city in south central Russia. They hacked websites inside Russia as well as big companies in the U.S. and other countries ,The New Times reports.
The criminals found hundreds of thousands of weak websites and attacked their coding，Hold Security said. Alex Holden is chief information security officer of Hold Security. “The hackers did not just target U.S. companies；they targeted any website they could get，” Holden said. “And most of these sites are still easy to attack”.
According to Hold Security, the criminals have been using the stolen information to send junk mail through e-mail and on social networks like Twitter. They can also use the 500 million stolen e-mail -addresses to plan other crimes. They could use information from bank e-mails to steal your identity or sell the e-mail address to other criminals to make quick cash.
The reported break-ins are the latest events to raise doubts about security at big and small companies. Last winter, hackers stole 40 million credit card numbers and 70 million addresses, phone numbers and other personal information from the retailer Target Corp. The brand is still working to regain its shoppers' trust.
John Prisco is a CEO of a security firm. He says security hacks are more common than many people and companies realize. "This issue reminds me of an iceberg, where 90% of it is actually under water," Prisco said in an e-mailed statement. So many cyber breaches today are not actually reported, because companies are losing information and they are not even aware of it. "
Security experts believe hackers will continue breaking into computer networks unless companies become more protective of personal information. What did a group of Russian criminals do according to the report?
| A．They stole e-mail addresses of the Internet users. |
| B．They destroyed the websites of some big companies. |
| C．They attacked American companies in southern Russia. |
| D．They downloaded the secret information of some banks. |
According to Alex Holden, the criminals entered some websites easily because .
| A．some websites don't have their own coding |
| B．most of the websites lack protective measures |
| C．Russia is more developed in computer science |
| D．the hackers are equipped with high technology |
What does Paragraph 4 mainly talk about?
| A．The criminals are fond of using social networks. |
| B．The criminals sell the stolen information for money. |
| C．The stolen information causes great economic losses. |
| D．The stolen information could bring harmful effects. |
What does the underlined sentence in Paragraph 6 imply?
| A．We cannot tell how large an iceberg is just from the part on the water. |
| B．Many companies are unwilling to report their information stolen. |
| C．Many companies are not aware their information has been stolen. |
| D．People usually can see just a small part of an iceberg. |
“Tear’ em apart!” “Kill the fool!” “Murder the referee (裁判)!”
These are common remarks one may hear at various sporting events. At the time they are made, they may seem innocent enough. But let’s not kid ourselves. They have been known to influence behavior in such a way as to lead to real bloodshed. Volumes have been written about the way words affect us. It has been shown that words having certain connotations (含义) may cause us to react in ways quite foreign to what we consider to be our usual humanistic behavior. I see the term “opponent” as one of those words. Perhaps the time has come to delete it from sports terms.
The dictionary meaning of the term “opponent” is “adversary” “enemy”; “one who opposes your interests.” Thus, when a player meets an opponent, he or she may tend to treat that opponent as an enemy. At such times, winning may dominate one’s intellect, and every action, no matter how gross, may be considered justifiable. I recall an incident in a handball game when a referee refused a player’s request for a time out for a glove change because he did not consider them wet enough. The player proceeded to rub his gloves across his wet T-shirt and then exclaimed. “Are they wet enough now?”
In the heat of battle, players have been observed to throw themselves across the court without considering the consequences that such a move might have on anyone in their way. I have also witnessed a player reacting to his opponent’s international and illegal blocking by deliberately hitting him with the ball as hard as he could during the course of play. Off the court, they are good friends. Does that make any sense? It certainly gives proof of a court attitude which departs from normal behavior.
Therefore, I believe it is time we elevated (提升) the game to the level where it belongs there by setting an example to the rest of the sporting world. Replacing the term “opponent” with “associate” could be an ideal way to start.
The dictionary meaning of the term “associate” is “colleague”; “friend”; “companion.” Reflect a moment! You may soon see and possibly feel the difference in your reaction to the term “associate” rather than “opponent.”Which of the following statements best expresses the author’s view?

As temperatures go up, bison（北美野牛）get smaller. Joseph Craine, research assistant professor in the Division of Biology at Kansas State University, examined how climate change during the next 50 years will affect grazing（放牧）animals such as bison and cattle in the Great Plains.
“Bison are one of our most important conservation animals and hold a unique role in grasslands in North America,” Craine said. “In addition to their cultural and ecological significance, they’re economically important. There are about half a million bison in the world.” Craine analyzed a data set of 290,000 weights, ages and sexes collected from 22 bison herds（兽群）throughout the U. S. The organizations kept annual records of each animal in the herd and matched the data with the climates of the sites.
Based on differences in sizes of bison across herds, Craine found that during the next 50 years, future generations of bison will be smaller in size and weigh less. Climate is likely to reduce the nutritional quality of grasses, causing the animals to grow more slowly.
“We know that temperatures are going to go up,” Craine said. “We also know that warmer grasslands have grasses with less protein（蛋白质）, and we now know that warmer grasslands have smaller grazers. It all lines up to suggest that climate change will cause grasses to have less protein and cause grazers to gain less weight in the future.”
Craine said the results of climate change in coming decades can already be seen by comparing bison in cooler, wetter places with those in warmer, drier places. For example, the average 7-year-old male bison in South Dakota weighed 1, 900 pounds, while an average 7- year-old male bison in Oklahoma — a warmer place — weighed 1, 300 pounds.
“The difference in temperature between those two states is around 20 degrees Fahrenheit, which is about three times the projected increase in temperatures over the next 75 years,” Craine said. “It is a clear indicator that long-term warming will affect bison and is something that will happen across the U.S. over the next 50-75 years.”In the next fifty years, researchers Say, bison will ________.
| A．become smaller and lighter |
| B．disappear in the Great Plains |
| C．play a less important part |
| D．adapt to different climate changes |
The underlined word “grazers” probably refers to ________.
| A．the researchers | B．the grasses |
| C．the bison | D．the protein |
What is the main reason for the bison to become smaller?
| A．The deceasing amount of grass. |
| B．The rising temperature. |
| C．The rising number of bison. |
| D．The loss of weight. |
Paragraph 5 is written as an example to show ________.
| A．Craine’s prediction will come true in 50 years |
| B．bison are smaller than in the past |
| C．the nature balance is being destroyed |
| D．bison’s size is linked with different climate |
A new research of 8,000 young people in the Journal of Health and Social Behavior shows that although love can make adults live healthily and happily, it is a bad thing for young people. Puppy love (早恋) may bring stress for young people and can lead to depression . The study shows that girls become more depressed than boys, and younger girls are the worst of all.
The possible reason for the connection between love and higher risk of depression for girls is “loss of self”. According to the study, even though boys would say “lose themselves in a romantic relationship”, this “loss of self” is much more likely to lead to depression when it happens to girls. Young girls who have romantic relationships usually like hiding their feelings and opinions. They won’t tell that to their parents.
Dr Marian Kaufman, an expert on young people problems, says 15% to 20% young people will have depression during their growing. Trying romance often causes the depression. She advises kids not to jump into romance too early. During growing up, it is important for young people to build strong friendships and a strong sense of self. She also suggests the parents should encourage their kids to keep close to their friends, attend more interesting school activities and spend enough time with family.
Parents should watch for signs of depression—eating or mood changes —and if they see signs from their daughters or sons, they need to give help. The good news is that the connection between romance and depression seems to become weak with age. Love will always make us feel young, but only maturity gives us a chance to avoid its bad side effects.
| A．Young people who have a strong sense of selfishness. |
| B．Young boys whose parents watch for their behavior. |
| C．Young girls who always hide their feelings and opinions. |
| D．Careless parents whose children are deep in love. |
| A．Lacking love can lead young people to grow up more quickly. |
| B．The older a woman is，the less likely she seems to lose herself in romance. |
| C．Early love makes young people keep close to their friends and parents. |
| D．Parents should help their children to be aware of the signs of depression. |
| A．Confused. | B．Disinterested. |
| C．Scared. | D．Disapproving. |
| A．Parents should forbid their children’s love. |
| B．Puppy love may bring young people depression. |
| C．Romance is a two edged sword for adults. |
| D．Romance is good for young people. |
This is VOA. The National Cryptologic Museum is on Fort George G. Meade, a military base near Washington, DC. The method of hiding exact meanings is called coding. People have used secret codes throughout history to protect important information. The National Cryptologic Museum celebrated 60 years of cryptologic excellence in 2012. One event there marked the sixtieth anniversary of the National Security Agency. Two former NSA workers shared their memories of operating a code machine called Sigaba.
In 1940, an American woman named Genevieve Grotjan found some information being repeated in Japanese coded messages. Her discovery helped the United States understand secret Japanese diplomatic messages. After the United States understood the code, it was possible to study messages from the Japanese ambassador to Germany and to his supervisors in Japan.
Understanding these messages helped the United States prepare for a possible war in the Pacific with Japan. After the attack on Pearl Harbor. the American naval commander in the Pacific Ocean was Chester Nimitz. His forces were much smaller than the Japanese Naval forces. And the Japanese had been winning many victories. Joseph Rochefort had worked for several months to read the secret Japanese Naval code called JN-25. If he could understand enough of the code, he would be able to give Admiral Nimitz very valuable information.
From the beginning of 1942, the Japanese code discussed a place called "AF." Joseph Rochefort felt the Japanese were planning an important battle aimed at "AF." After several weeks, he and other naval experts told Admiral Nimitz that their best idea was that the "AF" in the Japanese code was the American-held island of Midway. Admiral Nimitz said he must have more information to prepare for such an attack.
The Navy experts decided to trick Japan. They told the American military force on Midway to broadcast a false message. The message would say the island was having problems with its water-processing equipment. The message asked that fresh water be sent to the island immediately. This message was not sent in code.
Several days later, a Japanese radio broadcast in the JN-25 code said that "AF" had little water. Joseph Rochefort had the evidence he needed. "AF" was now known to be the island of Midway. He also told Admiral Nimitz the Japanese would attack Midway on June 13.The battle that followed was a huge American victory. That victory was possible because Joseph Rochefort learned to read enough of the Japanese code to discover the meaning of the letters "AF."
One American code has never been broken. Perhaps it never will. It was used in the Pacific during World War Two. For many years the government would not discuss this secret code. Listen for a moment to this very unusual code. Then you may understand why the Japanese military forces were never able to understand any of it.
The code is in the voice of a Native American. The man you just heard is singing a simple song in the Navajo language. Very few people outside the Navajo nation are able to speak any of their very difficult language.
At the beginning of World War Two, the United States Marine Corps asked members of the Navajo tribe to train as Code Talkers.
The Cryptologic Museum says the Marine Corps Code Talkers could take a sentence in English and change it into their language in about 20 seconds. A code machine needed about 30 minutes to do the same work.
The Navajo Code Talkers took part in every battle the Marines entered in the Pacific during World War Two. The Japanese were very skilled at breaking codes. But they were never able to understand any of what they called "The Marine Code."
The Cryptologic Museum has many pieces of mechanical and electric equipment used to change words into code. It also has almost as many examples of machines used to try to change code back into useful words.The NSA was founded__________.
| A．in 1940 | B．1942 |
