Living an Adventurous Life
Nearly ten years ago, I was told that I had a brain tumor （瘤）, and this experience changed my attitude about adventure forever．I thought that I was going to die and that all my adventures were over．I did not have a brain tumor, it turned out, but rather multiple sclerosis （多发性硬化症）, which meant that, although they were not over, the nature of my adventures could have to change．
Each morning that I wake up is a fresh event, something that I might not have had．Each gesture that I make carries the weight of uncertainty and demands significant attention: buttoning my shirt, changing a light bulb, walking down stairs．I might not be able to do it this time．If I could not delight in them, they would likely drown me in anger and in self-pity．
I admire the grand adventures of others．I read about them with interest．With Peter Matthiessen I have hiked across the Himalayas to the Crystal Mountain．I have walked with Annie Dillard up, down, into, and across Tinker Creek in all seasons．David Bain has gone with me along 110 miles of Philippine coast, and Ed Abbey has rowed me down the Colorado River．I enjoy the adventures of these courageous figures, who can strike out on difficult trips – 2 miles, 250 miles, 3000 miles – ready to bear cold and tiredness, indeed not just to bear but to celebrate．
But as for me, I can no longer walk very far from the armchair in which I read．Some days I don’t even make it to the backyard．And yet I’m unwilling to give up the adventurous life, the difficulty of it, even the pain, the anxiety and fear, and the sudden brief lift of spirit that makes a hard journey more attractive．
I refine adventure, make it smaller and smaller．And now, whether I am moving on my hands and knees across the dining room to help my cat, lying wide-eyed in the dark battling another period of sadness, gathering flowers from the garden, meeting a friend for lunch, I am always having the adventures that are mine to have．Which of the following is TRUE about the author’s reaction after the illness?
| A．The author is drowned in anger and self-pity． |
| B．The author travels to places he/she has dreamed of． |
| C．The author can’t take care of himself/herself any longer． |
D．The a uthor adapts to the condition successfully． |

Which of the following shows the author’s strong love for adventures?
| A．The author spends almost every day looking for adventures． |
| B．The author works hard to make more money for adventures． |
| C．The author imagines having adventures while reading． |
| D．The author expects to recover only to continue adventures． |
The hottest show this summer-the “Voice” just finished on Sunday at the Shanghai Stadium．But the show that had a good start didn't end to everyone's satisfaction．The two and a half hour show dragged on for more than four hours because of the huge amount of advertising, which the audience and residents（居民） living nearby could hardly bear．
This summer, something hotter than the weather came to Shanghai. That is the Voice of China．The show soon became a cash cow for the organizer as the advertisement prices reached 1.16 million yuan for 15 seconds. And the show has earned more than 100 million yuan up to now in ad income only. But the organizers’ bliss（快乐） was audiences’ melancholy（悲哀）．
In the final live show on Sunday, about 14 rounds of advertisements were aired, each of which came at a crucial result-announcing moment.
Frequently interrupted by advertisements, some audience complained that the show wasn’t worth its ticket prices of 180 to 1680 yuan.
The planned two and a half hour show went two hours overtime because of the advertising. This annoyed audience members, and touched the nerves(神经) of residents living near the site.
Someone called the police, and the show is now facing punishment for going over-time and disturbing residents late at night.Why didn’t “the Voice” make audience satisfied?
| A．It failed to attract audience attention in the end． |
| B．It failed to make audience satisfied． |
| C．It increased by one and a half hours and audience couldn’t bear it． |
| D．It was full of so many advertisements that audience can’t tolerate them． |
Which of the following is TRUE according to the passage?
| A．The show lasted for two and a half hours. |
| B．Someone called the police because they can’t bear the noises late at night. |
| C．The show was worth its ticket prices because the audience watched many advertisements. |
| D．The show has earned more than 100 million yuan up to now totally. |
Which of the following can best serve as the title of the passage?
| A．The Voice of China—the most popular TV show of last summer. |
| B．The Voice of China—I want you. |
| C．The Voice of China—hard to say I love you. |
| D．The Voice of China—the noises of China. |
This passage is organized in the pattern of____.

With his game-winning three-pointer at the buzzer, Jeremy Lin (林书豪) finished the New York Knicks' dramatic reversed(扭转) victory to defeat the Toronto Rapters.
The Knicks have won six games in a row, and Jeremy Lin has put up impressive numbers during the continuous period of competitions. Although the season is still young, the Knicks have reversed course in just one week from the NBA's most disappointing team to a playoff (季后赛) contestant. Lin, not team's high-paid stars, has saved the Knicks season and likely coach D'Antoni's job.
After nearly 15 years of disappointing, sometimes unsuccessful seasons, Madison Square Garden is alive again, and New York City can't stop talking about the Knicks. To put things into perspective（角度）, consider this: Just several years back, Knicks fans protested nightly outside of the Garden calling for the team's ownership to fire their resented coach Isiah Thomas.
Now, Madison Square Garden Co. shares are at a record high, the Knicks' average household television rating is up 70 percent since Lin joined the starting lineup (首发阵容), and jersey sales are increasing very quickly. I watched the Knicks-Lakers game at a bar in Harlem, and have not felt that kind of energy from fans since the great playoff between the Knicks and Miami Heat in the late 1990s.
Beyond the Knicks, Lin may be saving the NBA as well. Just a few months back, the NBA took a massive credibility（威信）hit during a multi-month lockout（停工）, where the owners did not allow the players to go back to play until they accept the new salary levels. As a consequence, the season did not even begin until Christmas Day. Over the past few years, LeBron James' (勒布朗﹒詹姆斯) relatively long and unpleasant free-agent (自由职业球员) events, combined with poor play around the league, have angered fans and damaged the league's brand.
Lin is leading a one-week NBA basketball revival. His legendary story has inspired Asian-Americans, increased NBA sales in China, and turned the basketball world upside down. The passage is mainly about______
| A．why the New Yorkers thought well of Jeremy Lin |
| B．why Jeremy Lin became a member of the Knicks |
| C．how the Knicks defeated its opponents in a great playoff |
| D．how Jeremy Lin saved the Knicks, probably including the NBA |
According to the passage, Jeremy Lin's excellent performance saved the following except___
| A．The NBA |
| B．Coach Isiah Thomas |
| C．The Knicks |
| D．Madison Square Garden Co.’s shares |
The underlined word “young” in Paragraph 2 probably means "______"
| A．not old yet. | B．not completely grown. |
| C．in the development | D．in the early stage |
The NBA suffered the credibility crisis months ago because____
| A．The NBA delayed the season because of players’ wage disagreements |
| B．the NBA was disappointed at James’ free-agent event. |
| C．The NBA canceled the basketball match for the coming Christmas |
| D．James had a bad performance in the basketball court |
Which one of the following statements is TRUE according to the passage?
| A．These Knicks’ stars who were paid well saved the Knicks season |
| B．The Knicks didn’t satisfy its fans for nearly 15 years until this season |
| C．The fans objected to dismissing Coach Isiah Thomas outside the Garden |
| D．The owners and the players didn’t agree on raising the TV ratings |

AIDS’ Threat to Asia Grows
NEW DELHI----Just a few years ago, Mala was a typical middle-class Indian housewife. She cooked, cleaned and looked after her two small children.
Last year, her life took a tragic turn. Her husband died of AIDS; she was found out HIV-positive and her mother-in-law took her children away from her, saying they would get the disease. “When friends dropped for a visit, she would introduce me, saying, ‘She is my son’s widow. She has AIDS,’” said Mala. AIDS is now described as “explosive(炸药)” around the world. A study of a hospital in the port city of Durban in South Africa, where the world’s biggest and Africa’s second AIDS conference opened last Sunday, found that almost half the beds in medical wards (病房) were occupied by AIDS patients.
South Africa has one of the world’s fastest growing HIV infections, with 1,700 people infected daily, adding to the 4.3 million, or 10 percent of its population, living with HIV. Until now, Asia has been more successful in holding the AIDS virus than Africa, where the disease has killed about 12 million people.
AIDS is now threatening to surround many of Asia’s poverty-stricken countries. Countries in Asia, such as Cambodia, and Thailand, have HIV infection speeds over 1 percent. But the low speeds hide huge numbers of infected people, because of the population base.
In India, for example, 3.7 million are infected, more than in any other country except South Africa. In China, an estimated 860,000 people (the actual number may be a little larger), mainly drug users, live with HIV/AIDS. Gordon Alexander, a senior advisor for UN AIDS in India, estimates that the number hit by AIDS in Asia will climb about eight million over the next five years from about six million.
In many Asian countries, the battle against HIV is a social and cultural one against public discussion of sexual health put a nationwide media campaign into action to limit the speed of HIV through unsafe sex. Brenton Wong, an official for Singapore’s Action for AIDS, says the actual HIV incidence in the city state of 3.9 million people is at least eight times higher than official data. “Shame and deny is still very, very common so people are afraid to get tested and many times won’t even tell their families if they test positive,” said Wong. We can conclude from the underlined sentence in the last paragraph that ______.
A．The official data always tell lies and cheat people to hide the truth. |
| B．3.9 million people in Singapore suffered from AIDS. |
| C．Singapore has a population of 3.9 million |
| D．The number of people infected with HIV is at least eight times larger than that of the AIDS patients in Singapore. |
It is judged that there are ______ people hit by AIDS in Asia or so.
| A．4.3 million | B．6 million | C．8 million | D．3.7 million |
According to the passage, the main reasons that AIDS spread in Asia is through_______.
A． blood |
B．unsafe sex | C．love | D．drugs |
Which of the following statements is not right?
| A．The battle against Aids in many Asian countries is against their culture and social customs. |
| B．Though the HIV infection in Asia develops with low speed, the infected number is still quite large compared to other continents. |
| C．India has the second largest number of HIV infected people. |
| D．Aids might affect the poverty-stricken countries more severely. |
Studies show farmland in Africa is often lacking in important nutrients. But researchers say combining different farming methods may help.
Since the world food crisis several years ago, researchers have directed more of their attention to small farms. Most farms in areas south of the Sahara Desert are only about one or two hectares. One of the goals is to increase production without necessarily clearing more land to grow additional crops.
American researchers say that can happen with greater use of an agricultural system called perennation. It mixes food crops with trees and perennial plants – those that return year after year.
Mr. Reganold, who is with Washington State University, says poor soil may have resulted from years of weathering that washed away many nutrients. He says some farmers may have done more harm than good.
He estimates that up to two billion dollars worth of nitrogen, phosphorous and potassium is lost from African soil each year.
The scientist says the word perennation defines three systems that are already used in Africa. The oldest of the three is called evergreen agriculture. This is where farmers plant trees with their crops. John Reganold says farmers in Africa have been doing this for sixty years, but it seems to be growing in popularity.
The method is gaining widespread use in countries such as Niger, Burkina Faso, Malawi and Zambia. The trees are planted among maize, millet or sorghum crops. They not only add nitrogen to the soil through their roots, but also through their leaves when they fall off and break down. At other times of the year, the trees can protect plants from strong sunlight.
Mr. Reganold was one of three researchers who wrote a report about perennation. It was published in the journal Nature.Farmland in Africa ________.
| A．is often small in size |
| B．can produce more than enough crops for Africans |
| C．is short of important nutrients |
| D．has got the attention of scientists around the world |
Researchers focused their attention on small farmlands for the reason that ________.
| A．Africa was going through a food crisis |
| B．most farms in areas south of the Sahara Desert are small |
| C．there are not enough farmlands |
| D．farmers may grow additional crops on farmland |
The word“perennation”mentioned in this passage ________.
| A．is a farming method of planting food crops with trees |
| B．is a new farming method |
| C．can help African people produce more food than they need |
| D．is gaining widespread use around the world |
We can infer from the passage that ________.
| A．perennation will be widely used by farmers in Africa |
| B．American government will help African countries increase food production |
| C．African countries is short of farmland |
| D．some farmers are destroying their farmland in Africa on purpose |
This report is mostly likely to be a journal of ________.
| A．food | B．environment | C．agriculture | D．gardening |

Tensions have erupted over some barren rocks in the Pacific that you may never have heard of, but stay tuned—this is a boundary dispute(争端) that could get ugly and some day have far-reaching consequences for China, Japan, Taiwan and the United States.
The islands in dispute are called the Senkaku chain by Japan, the Diaoyu islands by China, and the Diaoyutai by Taiwan. All three claim the islands, which are really just five small islands and three barren rocks northeast of Taiwan, 200 miles off the Chinese coast.
The latest conflict occurred when a Chinese fishing boat collided(碰撞) with two Japanese naval ships trying to stop it near the islands. The Japanese prevented the Chinese captain from leaving the place for questioning and the two countries have been exchanging angry protests.
The reason to worry is that nationalists in both China and Taiwan see the islands as unquestionably theirs and think that their government has been weak in claiming this authority.
So far, wiser heads have generally won the argument on each side, but at some point a weakened Chinese leader might try to gain the legal right with the public by pushing the issue and recovering the islands. It would be a dangerous game and would have a disastrous impact on China-Japan relations, but if successful it would raise the popularity of the Chinese government.
In reality, of course, there is zero chance that the U.S. will honor its treaty(条约) with Japan over a few barren rocks. We're not going to risk a nuclear conflict with China over some islands that may well be China's. But if we don't help, our security relationship with Japan will be at the breaking point.
So which country has a better claim to the islands? My feeling is that it's China, although the answer isn't clear-cut. Chinese navigational records show the islands as Chinese for many centuries, and a 1783 Japanese map shows them as Chinese as well. Japan purported to “discover” the islands only in 1884 and took control of them by force only in 1895 when it also grabbed Taiwan.
The best approach would be for China and Japan to agree to refer the dispute to the International Court of Justice, but realistically that won't happen. And since some believe that the area is rich with oil and gas reserves, the claims from each side have become more insistent.
As Chinese nationalism grows, as China's navy and ability to project power in the ocean gains, we could see some military conflicts over the islands.
Taken from NewYork TimesThe underlined word “purported” (in Para.7) is closest in meaning to “_____”.
| A．happened | B．claimed | C．pretended | D．intended |
The latest conflict referred to in the passage occurred because _____.
| A．the Japanese government has bought the Diaoyu Islands from the Liyuans |
| B．two Japanese naval ships sailed in the Chinese sea around the Diaoyu Islands |
| C．the Japanese kept the captain of a fishing boat from returning for questioning |
| D．a fishing boat collided with two Japanese naval ships by design in the Japanese sea |
Which of the following is the author's personal idea?
| A．It is the two Japanese naval ships that are to blame for the conflict. |
| B．It is the Chinese captain of a fishing boat that is to blame for the conflict. |
| C．It is the U.S. that will honor its treaty with Japan over a few barren rocks. |
| D．It is China that has a better claim to the islands because of its navigational records. |
What can be inferred according to the passage?
| A．The claim from both sides has become more insistent. |
| B．Japan has navy and ability to power the Diaoyu Islands. |
| C．China is developing so quickly that it will declare a war on Japan. |

A meteorite (陨石) flew fast across the sky and exploded over central Russia on Friday, raining fireballs over a vast area and causing a shock wave that smashed windows, damaged buildings and injured l,200 people.
People heading to work in Chelyabinsk heard what sounded like an explosion, saw a bright light and then felt the shock wave.
According to Russian space agency Roscosmos, the fireball, travelling at a speed of 30km per second, had burnt very brightly across the horizon, leaving a long white trail that could be seen as far as 200km away. Car alarms went off, thousands of windows shattered and mobile phone networks were disrupted.
“I was driving to work, it was quite dark, but it suddenly became as bright as if it were day,” said Viktor Prokofiev, 36, a resident of Yekaterinburg in the Urals Mountains. “I felt like I was blinded by headlights.”
The meteorite, which weighed about 20 tons and may have been made of iron, entered Earth’s atmosphere and broke apart 30-50km above ground, according to Russia’s Academy of Sciences.
The energy released when it entered the Earth’s atmosphere was about several thousand tons, the academy said, the power of a small atomic weapon exploding.
No deaths were reported, but the Emergencies Ministry said 20,000 rescue and clean-up workers were sent to the region after President Vladimir Putin told Emergencies Minister Vladimir Puchkov to ease the disruption and help the victims.
The Interior Ministry said about l,200 people had been injured, at least 200 of them children, and most from broken pieces of glass.“While events this big are rare, an impact that could cause damage and death could happen every century or so. Unfortunately there is absolutely nothing we can do to stop impacts.”When did the meteorite incident happen?

Global financial big dogs are no match for China's "Da Ma", or housewives, who have crowded into gold stores across China, buying up 300 tons of gold over the past two weeks. No wonder gold prices have steadied after taking a dive.
During the May Day holiday, gold stores were crowded with mostly female customers. Most of them are middle-aged "Chinese housewives". This group of buyers has risen to fame recently. They are big spenders and are desperate to get their hands on a bargain. "I bought some gold jewellery and kept them as a gift for my son when he gets married," said a buyer from Shanghai.
The gold business is skyrocketing. "Our sales are growing by the day. Yesterday we sold more than ten million yuan of gold products," a gold store salesperson said. The gold rush in China started about two weeks ago thanks to a decline in global gold prices. Media reports suggest that Chinese housewives have spent about 100 billion yuan, or about 16 billion US dollars, purchasing 300 tons of gold since mid-April. That has helped support gold prices.
"Gold prices depressed since the middle of last month but have risen gradually. That is mainly due to the strong demand from Asian markets," said foreign trader Zhang Chen from Industrial & Commercial Bank of China. "Some people even joked that Chinese housewives have beaten Wall Street analysts." For Chinese people, with limited investment options, the only thing better than buying gold is buying gold at discount prices.What does the author mean by the underlined sentence of the first paragraph?
| A．The global big dogs can’t match with Chinese housewives. |
| B．China's "Da Ma" help a lot to support the global economic crisis. |
| C．Chinese housewives spend a great deal of money on gold. |
| D．Chinese housewives have a better consumption idea than global financial big dogs. |
The whole passage mainly developed_______ ?

On Oct4,2011 , I phone 4s made its international appearance at the press conference claimed by the Iphone cooperation . Ever since then , Iphone4s has become a hot cake and even made a fashion around the globe. Meanwhile , many new expressions come about in relationship with this type of high-tech products. “Jailbreak” is one of them.
“ Jailbreak” means to unlock the operating system of a mobile phone or other device so that it can run software which it is not normally authorized to use because of restrictions imposed（实施） by the device's manufacturer.
If someone jailbreaks a smartphone, tablet computer or other device（设备）, they use a special piece of software in order to remove the restrictions imposed by the manufacturer on the kind of applications that can be downloaded and run on the device. The concept of jailbreaking is most often associated with products from Apple Inc, such as the iPhone, iPod and iPad, which routinely restrict the user to applications licensed exclusively（独家地） by Apple and purchased via its App Store. As well as wanting to lift the restriction（解除限制） on what kinds of applications they can purchase, those who jailbreak often do so as a reaction against what they consider as a form of censorship（监控） imposed by Apple Inc in only allowing the use of their 'approved' apps.
The concept of jailbreaking dates back to July 2007, when it was applied to the iPhone within a month of the device's first release. This first occurrence related to the adding of custom ringtones（个性铃音）, but the idea quickly developed as a means to lift the restriction and equip the phone with games and other applications not licensed by Apple Inc. “jailbreak” means that________________.
| A．Criminals escape out of the jail |
| B．People make a great breakthrough in their life |
| C．It is a way to lift the restriction specially imposed by the Iphone manufacturer. |
| D．It’s a breakthrough beyond one’s dream. |
Which is probably the correct Chinese meaning of a hot cake？
| A．热蛋糕 | B．抢手货 | C．热门话题 | D．最高礼遇 |
Which one is the correct statement from this passage?
| A．The original mobile phones also require jailbreaking |
| B．People jailbreak not only in order to lift the restrictions of applications licensed by the Iphone Cooperation. |
| C．The concept of jailbreak is seldom associated with products from Apple Inc |
| D．The concept of jailbreak dates back to the twentieth century |
What happens inside the skull of a soccer player who repeatedly heads a soccer ball? That question motivated a challenging new study of the brains of experienced players that has caused discussion and debate among soccer players, and some anxiety among those of us with soccer-playing children.
For the study, researchers at the Albert Einstein College of Medicine in New York selected 34 adults, men and women. All of the volunteers had played soccer since childhood and now competed year-round in adult soccer leagues. Each filled out a detailed questionnaire developed especially for this study to determine how many times they had headed a soccer ball in the previous year, as well as whether they had experienced any known concussions (脑震荡) in the past.
Then the players completed computerized tests of their memory and other learning skills and had their brains scanned, using a complicated new M.R.I. technique which can find structural changes in the brain that can’t be seen during most scans.
According to the data they presented at a Radiological Society of North America meeting last month, the researchers found that the players who had headed the ball more than about 1,100 times in the previous 12 months showed significant loss of white matter in parts of their brains involved with memory, attention and the processing of visual information, compared with players who had headed the ball fewer times.
This pattern of white matter loss is “similar to those seen in traumatic (外伤的) brain injury”, like that after a serious concussion, the researchers reported, even though only one of these players was reported to have ever experienced a concussion.
The players who had headed the ball about 1,100 times or more in the past year were also generally worse at recalling lists of words read to them, forgetting or fumbling the words far more often than players who had headed the ball less.The passage is most probably a______.
| A．news report |
| B．research report |
| C．story for soccer players |
| D．text for doctors |
In which way can we find the structural changes in the brain?
| A．Computerized test. | B．Questionnaire.. |
| C．Scanning. | D．M.R.I. technique. |
From the passage we can conclude that frequent heading may have_____.
| A．significant effect on brain |
| B．little effect on one’s brain |
| C．nothing to do with the brain injury |
| D．one’s memory improved |
The underlined word "fumbling" is closest in meaning to______.
| A．remembering | B．misunderstanding |
| C．recalling | D．missing |
“Global warming could make humans shorter,” warn scientists who claim to have found evidence that it caused the world's first horses to shrink(收缩) nearly 50 million years ago. In fact, a team from the universities of Florida and Nebraska says it has found a link between the Earth heating up and the size of mammals – horses, in this case.
The scientists used fossils to follow the evolution of horses from their earliest appearance 56 million years ago. As temperature went up，their size went down, and vice versa（反之亦然）;“ At one point they were as small as a house cat,” said Dr Jonathan Bloch, curator（博物馆长） of the Florida Museum of Natural History, which was quoted by the "Daily Mail" as saying.
The scientists say that the current warming could have the same effect on mammals and could even make humans smaller."Horses started out small, about the size of a small dog . What's surprising is that after they first appeared, they then became even smaller and then dramatically increased in size, and that exactly corresponds to the global warming event, followed by cooling”
"It had been known that mammals were small during that time and that it was warm, but we hadn't realized that temperature specifically was driving the evolution of body size," Dr Bloch said in the "Science" journal.How did scientists find out the horses’ earliest appearance millions of years ago?

A friendly English Springer Spaniel named Bonnie, who also happens to be deaf, is being praised by her owner for helping him catch a suspected intruder(入侵者，闯入者) in their Salem home.
Dan Strasser said he heard Bonnie running around the living room at about 6 a.m. Saturday, so he got out of bed to see why she was so excited.
"She smelled him because she does have a very good sense of smell," said Strasser. "She jumped up and got all excited thinking someone was there to play."
He said Bonnie didn't bark or bite like a guard dog, but the commotion she made was enough to alert him.
When he walked into the living room, Strasser said he caught the intruder trying to steal his laptop. Strasser said the man took off, but instead of running out the back door where he came in, he accidentally ran into the garage, where he was cornered.
"As you can imagine there's a lot going on in his mind, like ‘How do I get out of this place?' It's dark and he doesn't know it."
Strasser said he grabbed his gun and held the intruder in the garage while his girlfriend called 911.
"There was a lot of, ‘I'm sorry,'" said Strasser. "He starts talking about how he wants to go home and see his kid and asks if I would please let him go. All the stuff you'd say if you're caught and you don't want to go to jail."
Police showed up and arrested the intruder, who they later identified as Thomas Lowell, 25. He was arraigned in court Monday on charges of burglary and possession of methamphetamine. He is due back in court Oct. 2.
Strasser said Lowell got in through the back door, which he kept open at night so Bonnie could get into the backyard. He plans to keep it closed and locked from now on.What does the underlined word mean?
| A．sudden noise |
| B．happily rolling |

Cotton farmers in some Indian villages are busily buying Coca-Cola and Pepsi, believing that the sugar in the fizzy(有 泡 沫 的 ) drinks kills pests.
Farmers say scientists advised them to mix pesticides with a sugary juice to control pests, and they found the mixture cheaper and more effective than pure chemicals— although soft drink makers and scientists dismissed the remarks. N. Hamunayya, who has become a famous person in his village in the southeastern state of Andhra Pradesh, said his crop survived an attack of pests which had resisted other pesticides. “We found that all the colas had uniform effect on pests. The pests became dead and fell to the ground, ”he said. He said the drinks had all the elements they needed : they were cheaper, sticky, fizzy, and attracted ants, which ate the young of the pests. But Thinupathi Reddy, assistant director of the Regional Agri-Research Station, Guntur, says tests had proved such results wrong. “We conducted some field trials on cotton crop at our research station. There was no obvious productivity or destruction of pests, ”he says.
Statements from Pepsi and Coca-Cola said there was “ no scientific basis” for this practice. But their dealers are enjoying increasing sales. Mantan Wall, who sells soft drinks in 17 villages in the region, said sales rose up, thanks to the farmers. “ For the 10 days between August and September I had successful business. Instead of just 30 cases( each containing a dozen one-litre bottles) of cola, I started selling almost 200 cases, ”he said. “ We expected the sales to drop after the news over pesticide residues(残 留 ) in the cola drinks. Now I have to keep extra supply for the cotton farmers, ”he said.
In February, an Indian environment group made a report saying drinks made by Coca-Cola and Pepsi contained pesticides and called for tougher safety standards. The U. S firms strongly rejected the findings of the New Delhi-based Centre for Science and Environment and said their products were safe.The writer’ s purpose of writing this passage is to .
| A．tell an interesting incident |
