PALO ALTO, California—“Switching off the television may help prevent children from getting fatter—even if they do not change their diet or increase the amount they exercise, ”US researchers said last week.
A study of 192 third and fourth graders, generally aged eight and nine, found that children who cut the number of hours spent watching television gained nearly two pounds(0.9 kg) less over a one-year period than those who did not change their television diet.
“The findings are important because they show that weight loss can only be the result of a reduction in television viewing and not any other activity,” said Thomas Robinson, a pediatrician(儿科专家) at Stanford University.
“American children spend an average of more than four hours per day watching television and videos or playing video games, and rates of childhood being very fat have doubled over the past 20 years,” Robinson said.
In the study, presented this week to the Pediatric Academic Societies' annual meeting in San Francisco, the researchers persuaded about 100 of the students to reduce their television viewing by one-quarter to one-third.
Children watching fewer hours of television showed a significantly smaller increase in waist size and had less body fat than other students who continued their normal television viewing, even though neither group ate a special diet or took part in any extra exercise.
“One explanation for the weight loss could be that the children unstuck to the television may simply have been moving around more and burning off calories,” Robinson said.
“Another reason might be due to eating fewer meals in front of the television. Some studies have suggested that eating in front of the TV encourages people to eat more,” Robinson said.The author tries to tell us in the first two paragraphs that _______.
| A．children will get fatter if they eat too much |
| B．children will get thinner if they eat less |
| C．children will get fatter if they spend less time watching TV |

When newspapers and radio describe the damage caused by a hurricane named Hazel,girls named Hazel are probably teased by their friends.To keep out of trouble,the Weather Bureau says,“Any resemblance between hurricane names and the names of particular girls is purely accidental.”
Some women became angry because hurricanes are given their names,but many other women are proud to see their names make headlines.They don’t even care that they are the names of destructive storms.Because more women seem to like it than dislike it,the Weather Bureau has decided to continue using girl’s names for hurricanes.
In some ways a hurricane is like a person.After it is born,it grows and develops,then becomes old and dies.Each hurricane has a character of its own.Each follows its own path through the world,and people remember it long after it gone.So it is natural to give hurricanes’ names,and to talk about them almost if they were alive.What happens to girls named Hazel according to the passage?
| A．They suffer from hurricanes. |
| B．The Weather Bureau look for them. |
| C．Others often make fun of them. |

A teddy bear from Cumbria is launching into space to raise cash for charity(慈善).
Terence, an experienced traveller who has been to Iraq, will be the guest of honour on aviation(航行) legend Burt Rutan’s Spaceship One when it flies above Earth. The mission takes off from California on September 29, and on his return the cuddly toy will be auctioned off(拍卖) in aid of the North Air Ambulance Appeal(北部空中救护服务中心).
Spaceship One is the world’s first private spacecraft, and is competing for a prestigious space travel prize. Chief executive of the Great North Air Ambulance Service (GNAAS), Graham Pickering, said “flying officer” Terence had been handed over to the RAF six months ago and staff had been receiving postcards from him ever since.
He said, “Terence was a fundraising idea that really took off. We have received pictures of him in a U2 craft, trying parachuting and even looking drunk and disorderly. When the RAF finally discharge him he will be a very rare bear indeed—we just hope he does not burn up on re-entry to Earth.”
GNAAS, which needs charitable donations of more than ￡2m a year, has three air ambulances(空中救护机).
Peter Bond, spokesman for the Royal Astronomical Society, said Terence’s safety was not guaranteed. He said, “This is a new and experimental craft and this will only be the second time it has flown. During its first voyage it developed technical problems but hopefully they have now been resolved.”
Since May, Terence has spent time with members of 100 Squadron(空军中队) based at RAF Leeming in Basra, Iraq, and at air shows with performing fighter planes.
Spaceship One will fly 100km (62 miles) above the Earth’s surface, just breaking through the planet’s atmosphere.
If it repeats the feat(技艺) inside two weeks, it will claim the $10m Ansari X-Prize set up to encourage the private space flight business.Terence is ________.
| A．a real bear living in England | B．an experienced astronaut |
| C．an air force officer | D．a toy bear |
We can infer that________.
| A．after this space flight, Spaceship One will get the $10m Ansari X-Prize |
| B．it is dangerous for a spaceship to re-enter the earth atmosphere |
| C．Terence will be very safe on the flight |
| D．Spaceship One is just an ordinary plane |
Which of the following is true of Spaceship One?
| A．Spaceship One is the world’s first spacecraft. |
| B．The purpose of its flight is to collect money for the charity. |
| C．The purpose of its flight is to compete for a prestigious space travel prize. |
| D．Spaceship One has never flown. |
Which of the following is the best title?
| A．Teddy bear astronaut to lift off | B．Spaceship One to lift off |
| C．Space flight | D．The toy bear will be auctioned off |
You are a German living in Berlin. One day you’ re walking down the street, minding your own business, when suddenly a stranger comes up with a smile on his face. After stopping you, he holds a small electronic device (装置) close to his face and speaks slowly into it, saying, in English," Can you tell me where I can buy some sauerkraut?" What should you do? (a) Run away; (b) Call the police; or (c) Listen closely for the device to say in German," Konnen Sie mir bitte sagen, welches sauerkraut haufen kann?"
The most proper answer would be (c) because the person in front of you is only a tourist trying to enjoy himself. The device is said to be the world’s first portable(便携的) translator — a hand-held microcomputer that at the same time translates one spoken language into another. The four-pound, battery-operated product is called the Voice, and it is the invention of Advanced Products and Technologies, an American electronics company. When the Voice is introduced in the Unite States in late April — at a price of (1,500 — it will be used to translate spoken English into Italian, German, French and Spanish. The product comes with separate cartridges(盒式存储器) for each of the four languages, which can be changed when the user travels from one country to another. It will be sold in Europe soon after the US introduction, with cartridges that translate Italian, German, French and Spanish into English.
The Voice uses a microchip(微型集成电路片) to translate languages. It is Started by voice command and produces voice output through a built-in speaker. When the user makes a statement or asks a question, the Voice immediately repeats what has been said in another language. The device held by the stranger is probably a kind of________.
| A．a two-way radio | B．language translator |

Being able to multitask—doing several things at the same time—is considered a welcome skill by most people. But if we consider the situation of the young people aged from eight to eighteen, we should think again.
What we often see nowadays is that young people juggle an ever larger number of electronic devices(电子产品)as they study. While working, they also surf on the Internet, send out emails, answer the telephone and listen to music on their iPods. In a sense, they are spending a significant amount of time in fruitless efforts as they multitask.
Multitasking is even changing the relationship between family members. As young people around them. They can no longer greet family members when they enter the house, nor can they cat at the family table.
Multitasking also affects young people’s performance at university and in the workplace. When asked about their opinion of the effect of modern gadgets(器具)on their performance of tasks, many young people gave a positive response(反应). However, the response from the worlds of education and business was not quite as positive. Educators feel that multitasking by children has a serious effect on later development of study skills. They believe that many college students now need help to improve their study skills. Similarly, employers feel that young people entering the job market need to be taught all over again, as modern gadgets have made it unnecessary for them to learn special skills to do their work.
What does the underlined word “juggle” in Paragraph 2 most probably mean?
| A．Want to buy | B．Take the place of. |
| C．Use at the same time | D．Seek for information from. |
In Paragraph 3, the author points out that .
| A．family members do not cat at the family table |
| B．family member do not greet each other |
| C．young people live happily in their families |
| D．young people seldom talk with their family members |
What is the main idea of the last paragraph?
| A．Multitasking is harmful to young people’s development. |
| B．Young people benefit a lot from modern gadgets |
| C．Multitasking is an important skill to young people. |
| D．Young people must learn skills for future jobs. |
The author develops the passage mainly by .
| A．providing typical examples | B．following the natural time order |
| C．comparing opinions from different fields | |
| D．presenting a cause and analyzing its effects |
While all my classmates seen to be crazy about a one-way ticket to Mars(火星), I’d rather say Mars is totally unsuitable for human existence. People won’t have enough food supplies there, and the terrible environment would make it impossible for them to live a long life. Besides, the journey won’t be safe. Can anybody explain to me just why people would go to Mars, never to return?
Steve Minear, UK
Here are the things you can think of: the desire to explore a foreign and unique environment, the excitement of being the first humans to open up a new world, the expectation of fame and glory…For scientists there is another reason. Their observations and research will probably lead to great scientific achievements.
Donal Trollop, Canada
There are already too many people on the Earth. I think that sometime before the end of the century, there will be a human colony(殖民地)on Mars. It will happen when people finally realize that tow-way trips to the red planet Mars are unnecessary. Most of the danger of space Flight is in the launches(发射) and landings. Cutting the trip home would therefore reduce the danger of accidents, save a lot of money, and open the way to building an everlasting human settlement on another world.
Enough supplies can be sent on ahead. And every two years more supplies and more people will needs, and Mars is far more pleasant than the other planets in the outer space.

If your boss asks you to work in Moscow this year, he'd better offer you more money to do so - or even double that depending on where you live now. That's because Moscow has just been found to be the world's most expensive city for the second year in a row by Mercer Human Resources Consulting.
Using the cost of living in New York as a base, Mercer determined Moscow is 34.4 percent more expensive including the cost of housing, transportation, food, clothing, household goods and entertainment(娱乐).
A two-bedroom flat in Moscow now costs $4,000 a month; a CD $24.83, and an international newspaper $6.30, according to Mercer. By comparison, a fast food meal with a hamburger(汉堡包) is a steal at $4.80.
London takes the No.2 place, up from No.5 a year ago, thanks to higher cost of housing and a stronger British pound relative to the dollar. Mercer estimates(估算) London is 26 percent more expensive than New York these days. Following London closely are Seoul and Tokyo, both of which are 22 percent more expensive than New York, while No.5 Hong Kong is 19 percent more costly.
Among North American cities, New York and Los Angeles are the most expensive and are the only two listed in the top 50 of the world's most expensive cities. But both have fallen since last year's study - New York came in 15th, down from 10th place, while Los Angeles fell to 42nd from 29th place a year ago. San Francisco came in a distant third at No. 54, down 20 places from a year earlier.
Toronto, meanwhile, is Canada's most expensive city but fell 35 places to take 82nd place worldwide. In Australia, Sydney is the priciest place to live in and No. 21 worldwide.

Far from the land of Antarctica(南极洲), a huge shelf of ice meets the ocean. At the underside of the shelf there lives a small fish, the Antarctic cod.
For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? It must have some secret. The Antarctic is not a comfortable place to work and research has been slow. Now it seems we have an answer.
Research was begun by cutting holes in the ice and catching the fish. Scientists studied the fish’s blood and measured its freezing point.
The fish were taken from seawater that had a temperature of -1.88℃ and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until its temperature was lowered to -2.05℃. That small difference is enough for the fish to live at the freezing temperature of the ice-salt mixture.
The scientists’ next research job was clear: Find out what in the fish’s blood kept it from freezing. Their search led to some really strange thing made up of a protein(蛋白质) never before seen in the blood of a fish. When it was removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze quality and a lowered freezing point.
Study showed that it is an unusual kind of protein. It has many small sugar molecules(分子) held in special positions within each big protein molecule. Because of its sugar content. It is called a glycoprotein. So it has come to be called the antifreeze fish glycoprotein. Or AFGP.What is the text mainly about?
| A．The terrible conditions in the Antarctic. |
| B．A special fish living in freezing waters. |
| C．The ice shelf around Antarctica. |
| D．Protection of the Antarctic cod. |
Why can the Antarctic cod live at the freezing temperature?
| A．The seawater has a temperature of -1.88℃. |
| B．It loves to live in the ice-salt mixture. |
| C．A special protein keeps it from freezing. |
| D．Its blood has a temperature lower than -2.05℃. |
What does the underlined word “it” in Paragraph 5 refer to?
| A．A type of ice-salt mixture. | B．A newly found protein. |
| C．Fish blood. | D．Sugar molecule. |
What does “glycol-” in the underlined word “glycoprotein” in the last paragraph mean?

The small number of newborn babies, which has been caused by high prices and the changing social situation of women, is one of the most serious problems in Asia. When people talk about it, you can hear a word invented in Japan. which means Double Income Kids(小孩).
In many major Asian cities like Seoul, Singapore, and Tokyo, the cost of a ****** is extremely high. A young couple who want to buy their own house may have to pay about $3000,000 (though prices have fallen). For a flat with one bedrooms, one dining-room, a kitchen, and a bathroom, the couple will pay about $900 a month. What’s more, if they want to have a child, the child’s education is very expensive. For example, most kindergarten charges are at least $5.000 a year. In such a situation, it’s difficult to afford children.
The number of married women who want to continue working because they enjoy their jobs. However, if they want to have children, they immediately have serious problems. Though most companies allow women to leave their jobs for a short time to have a baby, they expect women with babies to give up their jobs. In short, if they want to bring up children properly, both parents have to work, but it is hard for mothers to work. Indeed, women who want to contimue working have to choose between having children or keeping their jobs.
In a word, Asian governments must take steps to improve the present situation as soon as possible.What is the main problem being discussed in the passage?

Intellectual property (IP) is a product of the mind that has commercial value. The concept dates back to 1623 when the first patent law to protect IP sights was passed. IP rights protect the artist from having his/her creative ideas copied by another. For example, if somebody generated an idea for a novel, that idea is protected by IP rights. If someone else wishes to represent the idea or develop it further, he/ she must consult the original artists, who will normally be rewarded financially for its use. Back in the 17th century, IP rights were primarily carried out to protect newly developed manufacturing processes against stealing. But today, intellectual property rights, are also enjoyed by those who creative music, art and literature.
In recent years, IP rights have been the focus of a great deal of discussion because of a technology which looks set to weaken them altogether; the Internet. Many years ago, if you wanted a recording of a song, you would have to purchase it from a music store; if a novel, form a book store. In those days, IP rights were easily protected since it was very difficult to obtain intellectual property without paying for it. However, a lot of IP, including songs, films, books and artwork, can be downloaded today free of charge using the Internet. This practice has now taken the world by storm, dramatically affecting the way in which we view IP rights.

Across the globe, single parent homes are on the rise. In the US, the 2000 census (人口普查) showed 24.8 million, or nearly 24 percent of the nation’s 105.5 million households, were traditional two-parent homes. By comparison, 9.8 million households, or 9 percent of all US households were headed by an adult raising a child alone. The 1990 census showed 26 percent of homes were led by a married mother and father, and 8 percent of homes were led by a single parent.
Similar increases occurred in other countries. In the UK, lone-parent homes increased from 3.3 percent in 1990 to 5.5 percent in 1999. Single parent households in Australia rose from 5.8 percent in 1990 to 7.6 percent in 1999. Belgium saw the increase from 1.8 percent to 2.7 percent during the same period of time. These countries tend to have greater acceptance of the single parent because there are fewer nearby family members to disapprove, Riche, a Census Bureau director, said.
Just as in the US, those changes raised new questions about how involved govenment should be in helping single parent families. Some research suggests children raised in two-parent families are better off than those who depend on one.
“The position of one-parent families in any country is very much a gender (性别) issue-women’s opportunities, especially working-class women on low income,” said Sue Cohen, coordinator (协调员) of the Single Action Parents Network in England.
5.Not considering the exact number of the single-parent families, which country saw the fastest rise rate in 1999, compared with 1990?
A.UK. B.Australia. C.America. D.Belgium.
6.What is the cause of the rise of single parent families across the globe?
A.The nearby family members have a favourable opinion.
B.A lone parent is well off enough to support his /her children.
C.A lot of problems have arisen in two-parent families.
D.We cannot get enough proving information from the text.
7.Which of the following is TRUE about the increase of single parent families according to the passage?
A.It will somewhat limit the growing population of younger generation.
B.Governments should take actions about the social problems brought about by it.
C.Single parent families are not looked down upon in any country mentioned here.
D.Generally speaking, the single parents needn’t worry since they are highly paid.
8.Which of the following diagrams correctly shows the rise of single parent families in the US from
1990 to 2000?
