    WASHINGTON(Reuters)-People who drink two or more sweetened soft drinks a week have a much higher risk of pancreatic cancer(胰腺癌)，an unusual but deadly cancer，researchers reported on Monday．

    People who drank mostly fruit juice instead of sodas did not have the same risk，the study

 of 60,000 people in Singapore found．

    Sugar may be to blame but people who drink sweetened sodas regularly often have other

poor health habits，said Mark Pereira of the University of Minnesota，who led the study．

    “The high levels of sugar in soft drinks may be increasing the level of insulin(胰岛素)in The body,which we think contributes to pancreatic cancer cell growth,”Pereira said in a statement．

    Writing in the joumal Cancer Epidemiology，Biomarkers & Prevention，Pereira and colleagues

said they followed 60,524 men and women in the Singapore Chinese Health Study for l4 years．

    Over that time，140 of the volunteers developed pancreatic cancer．Those who drank two or

more sweetened soft drinks a week had an 87 percent higher risk of being among those who got

pancreatic cancer．

   Pereira said he believed the fndings would apply elsewhere。

  “Singapore is a wcahhy country with excellent heahhcare．Favorite pastimes(消遣)are

eating and shopping，so the findings should apply to other western countries，”he said．

    But Susan Mayne of the Yale Cancer Center at Yale University in Connecticut was cautious．

   “Although this study found a risk，the finding was based on a relatively small number of

cases and it remains unclear whether it is a causal(因果的)connection or not。”said Mayne．

who serves on the board of the journal，which is published by the American Association for

Cancer Research．

    Pancreatic cancer is one of the deadliest forms of cancer，with 230,000 cases globally．In

the United States，37,680 people are diagnosed with pancreatic cancer in a year and 34,290 die

of it．

4 1．According to the text，who is in control of the health study?

    A．Mark Pereira．               B．Scientists from Singapore．

    C．Researchers in Yale．          D．Susan Mayne．

42．We can infer from Pereira,s words that__．

    A．the heahhcare in Singapore should be greatly improved

    B．2 soft drinks a day are considered harmful to health

    C．87 out of l40 volunteers developed pancreatic cancer

    D．sugar might not be the only cause of pancreatic cancer

A
Saving the Planet with Earth-Friendly Bamboo Products
Jackie Heinricher’s love affair with bamboo started in her backyard. “As a child, I remember playing among the golden bamboo my dad had planted, and when there was a slight wind, the bamboos sounded really musical.”
A fisheries biologist, Heinricher, 47, planned to work in the salmon industry in Seattle, where she lived with her husband, Guy Thornburgh, but she found it too competitive. Then her garden gave her the idea for a business: She’d planted 20 bamboo forests on their seven-acre farm. 
Heinricher started Boo-Shoot Gardens in 1998. She realized early on what is just now beginning to be known to the rest of the world. It can be used to make fishing poles, skateboards, buildings, furniture, floors, and even clothing. An added bonus: Bamboo absorbs four times as much carbon dioxide as a group of hardwood trees and releases 35 percent more oxygen.
First she had to find a way to mass-produce the plants—a tough task, since bamboo flowers create seed only once every 50 to 100 years. And dividing a bamboo plant frequently kills it.
Heinricher appealed to Randy Burr, a tissue culture expert, to help her. “People kept telling us we’d never figure it out,” says Heinricher. “Others had worked on it for 27 years! I believed in what we were doing, though, so I just kept going.”
She was right to feel a sense of urgency. Bamboo forests are being rapidly used up, and a United Nations report showed that even though bamboo is highly renewable, as many as half of the world’s species are threatened with dying out. Heinricher knew that bamboo could make a significant impact on carbon emissions (排放) and world economies, but only if huge numbers could be produced. And that’s just what she and Burr figured out after nine years of experiments—a way to grow millions of plants. By placing cuttings in test tubes with salts, vitamins, plant hormones, and seaweed gel, they got the plants to grow and then raised them in soil in greenhouses.
Not long after it, Burr’s lab hit financial difficulties. Heinricher had no experience running a tissue culture operation, but she wasn’t prepared to quit. So she bought the lab.
Today Heinricher heads up a profitable multimillion-dollar company, working on species from all over the world and selling them to wholesalers. “If you want to farm bamboo, it’s hard to do without the young plants, and that’s what we have,” she says proudly.
56. What was the main problem with planting bamboo widely?
A. They didn’t have enough young bamboo.      B. They were short of money and experience.
C. They didn’t have a big enough farm to do it.  D. They were not understood by other people.
57. What does Heinricher think of bamboo?
A. Renewable and acceptable                             B. Productive and flexible.
C. Useful and earth-friendly.                                 D. Strong and profitable.
58. The underlined word “renewable” in Paragraph 6 probably means “________”.
A. able to be replaced naturally                B. able to be raised difficultly
C. able to be shaped easily                    D. able to be recycled conveniently
59. What do you learn from the passage?
A. Heinricher’s love for bamboo led to her experiments in the lab.
B. Heinricher’s determination helped her to succeed in her work.
C. Heinricher struggled to prevent bamboo from disappearing.
D. Heinricher finally succeeded in realizing her childhood dream.

Coca Cola is an American icon – and sometimes seen as a symbol of the country’s economic right. But one of the world’s famous companies will play a different role during the 2008 Olympic Games: promoting Oriental (东方的) culture to the world.

The man who is in charge of the project couldn’t be more suited for the job. The American has lived in the country for about 15 years, speaks fluent Chinese, and considers Beijing his hometown. David Brooks, vice-president and general manager of the Olympics Project Group of Coca Cola China, who has lived in the country for more than a decade, said: "We are working very hard to create a lot of special different kinds of items that are very Oriental in character and have a strong Oriental identity. "There is a lot of curiosity around the world about the country and about Oriental culture. So, we think we also have a role and opportunity to show people so many things."

Coca Cola has launched its logo(标识) with the Beijing Games, featuring kites and lucky clouds, traditional elements in the Oriental culture. Brooks considers it a good start. "We are doing a lot of similar programs, and in the next 570 days or so, as we count down to the Games, you will see more examples with strong Oriental spirit and identity."

He certainly has a sense of history. "The Olympic spirit, which is an ancient spirit from over 2,000 years ago, is alive. It still lives through the Olympic Games in the idea of balancing the body and mind, and doing the best," said Brooks, who has been to three Games. "It's like a big family celebrating together. I think all the members of my team and I feel it is a special honor to be involved in the Games."

第一节，阅读下面短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项，并在答题卡上将该项涂黑。

Bollworms are a traditional threat to cotton crops．Young ones feed on the boll，the part of the cotton plant that contains the seeds．

A bacterium known as Bt is able to kill bollworms and some other pests．Bt is the short form for Bacillus thuringiensis．It was discovered in the early twentieth century．Farmers began using Bt as a natural pesticide(杀虫剂)．

Then，in the 1990s，researchers found a way to grow cotton plants that contain a Bt gene．The genetically improved cotton plant produces liquid that kills bollworms．Farmers around the world are now growing an estimated fourteen million hectares of Bt cotton．

Cotton bollworms also attack other crops．But scientists in China recently reported that Bt cotton may help prevent bollworm in other crops growing nearby．

The study involved crops grown in six provinces of northern China between 1992 and 2008．The study area contained three million hectares of cotton and twenty-two million hectares of corn，peanuts，soybeans and vegetables．

The researchers say the study suggested that Bt cotton not only controls bollworm on the transgenic cotton，but also may reduce its existence on other crops．And that reduction，they say，may decrease the need for insecticide use in general．

But the researchers also pointed out concerns．They say bollworms could develop resistance to the cotton plants designed to resist them．And they noted that insects called mirids have become “key pests” of cotton in China．They said this is because of a decrease in pesticide use made possible by Bt cotton．

The researchers say they do not believe that Bt cotton alone can solve all insect problems．Instead，they say farmers in China should consider it just one part of pest management systems．

1．What is Bt in this passage?

A．It's a kind of hi-tech invention．                   B．It's a natural bacterium．

C．It's a kind of pest．                        D．It's a man-made pesticide．

2．Bt cotton has all the advantages EXCEPT that ________．

A．it resists bollworms

B．it does good to other crops growing around

C．it reduces the use of insecticide

D．it helps to develop new insects

3．The underlined word “ones” in the first paragraph refers to ________．

A．bollworms          B．cotton crops         C．cotton seeds        D．pests

4．From the passage，we can infer ________．

A．farmers around the world are now growing a large area of Bt cotton

B．researchers are probably now searching for new ways to solve other cotton problems C．bollworms could not exist in Bt cotton any longer

D．Chinese scientists found the way to grow Bt cotton

Smoking is habit that’s closely linked to certain times and places. If you break these links, you can break the habit. The best way of doing this is to avoid the situations where you want a cigarette. If you can’t avoid them, then you will have to fight off the temptation（诱惑）. Sit down and think about when and where you usually have a cigarette. For example, do you always have one after breakfast? After other meals? In breaks at work? When you are watching television? With friends in the pub? Once you stop smoking, these times and places are going to be the danger spots. So work out how you are going to deal with them.

It will also help if you can make new habits to break the old one of smoking. So plan some new activities to replace smoking-things to draw away your attention, things to do with your hands, and different ways to deal with tensions.

Some people find it helps if they cut down on cigarettes before they actually give up. It’s one way of preparing for the day you stop for good. But don’t look on cutting down as an alternative to giving up, and don’t do it for more than a couple of weeks at the very most. The danger is that you go back to smoking more than you did before
