Exercise may hold the key to youth, according to a study published recently which showed people who keep fit are up to nine years biologically younger than those who do not.

The findings are the first to show in humans how keeping fit affects the ageing process.The study of 2,401 twins found that a sedentary (惯于久坐的) lifestyle raises the risk of a range of problems from heart disease to cancer and appears to play a key role in the ageing process.

It all appears to boil down to the length of structures called telomeres－which protect the DNA on the chromosomes(染色体), the researchers from King's College London wrote in the Archives of Internal Medicine.

Many studies have shown telomeres get shorter over time, suggesting the cells are ageing or dying. The study, which extracted a DNA sample from their volunteers, found people who exercised more each week had longer telomeres.

Exercise lowers the risk of a range of problems such as heart disease, diabetes(糖尿病) and cancer, the researchers said.

“It is not just walking around the block. It is really working up a sweat,” said Tim Spector, a genetic epidemiologist(流行病学家) who led the study, in a telephone interview.

The study found people who exercised vigorously 3 hours each week had longer telomeres and they were 9 years biologically younger than people who did under 15 minutes.

Spector’s team, who also adjusted for body weight, smoking, economic status and physical activity at work, also said moderate exercise for 1-1/2 hours each week provided a four-year advantage.

The reason why exercise has this effect is not clear but we believe physical activity somehow defends against the natural process.

1. Which of the following would be the best title of the passage?

A. Lifestyle affects people’s health B. Physical activity prevents diseases

C. Exercise keeps you younger D. Sitting long suffers from cancer

2. According to the study, people sitting long .

A. are tending to be more healthy B. are more likely to live longer

C. are inclined to be taken ill D. are getting old more slowly

3. The underlined phrase “boil down to” most probably means .

A. lie in B. lead to C. aim at D. show up

4. Which of the following statements are NOT true?

A. Telomeres get shorter as time goes on.

B. Slight walking prevents people getting ill.

C. Exercise energetically reduces the chance of diseases.

D. Body weight, smoking and economic statusaffect people’s health.

5. It can be inferred from the passage that .

A. people’s health is decided by their body weight and economic status

B. scientists have known why exercise affects the ageing process

C. the more violently one exercises, the healthier one gets

D. the longer telomeres one has, the more slowly one gets old

Now scientists believe that global warming affects hibernating animals, causing them to wake up earlier. While this may seem a little concern, it is in fact a significant environmental problem. The shortened hibernation period could actually lead to significant declines in the populations of several species

Some of the first concrete evidence of the phenomenon came from Colorado, where researchers at the Rocky Mountain Biological lab have been observing marmot（旱獭）hibernation behavior since the 1970s. In the early days of their studies, marmots generally hibernated several weeks into the month of May. Nowadays, however, temperatures in the area have risen by 2.5 degrees Fahrenheit, and the marmots are waking up about a month earlier.

At least the marmots are still hibernating. Several other animals have not been hibernating at all recently. Brown bears in the Spanish Cantabrian Mountains did not hibernate last year. In parts of the United States, chipmunks（花鼠）also skipped the hibernation period. The bears seem to have survived without losing many individuals. The chipmunks, however, were not so lucky. Many of the animals died of starvation during the winter.

The problem with animals waking up early, or skipping hibernation altogether, lies with the creatures’ metabolism（新陈代谢）. When an animal hibernates, their metabolism drops significantly. The animals’ heart rate slows, and they require very little energy to live. When the animals awake from their winter slumber, their metabolism returns to normal.

But while their metabolism may be as active as it was before hibernation, food sources aren’t as available as they were before. A marmot may wake up when temperatures get warmer, thinking it’s spring, but plants will not have gotten the amount of sun they need to signal their spring period of growth. So until the plants grow, the marmots have no reliable food source.

Many scientists believe the problem will continue to get worse. In addition to changes in hibernation patterns, some believe that other animals will also begin to change their migration patterns or begin to give birth earlier. For many biologists, that’s a scary prospect. Terry Root, an animal expert at Stanford University, said: “I do think what we will be facing is the extinction of many species."

6. What is the viewpoint of the writer?

A. Global warming will continue to get worse as time goes on.

B. Global warming will lead to shortened hibernation of some animals.

C. Shortened hibernation will result in declines in the population of animals.

D. Some animals will skip hibernation altogether.

7. The writer sets the example of the marmot so as to __________.

A. explain that global warming influences animals’ hibernation

B. indicate that the weather gets warmer and warmer now

C. show that the weather in the United States is quite different

D. say some animals do not hibernate now due to warm weather

8. The underlined word “slumber” in the fourth paragraph means “ _________”.

A. weather B. activity C. nest D. sleep

9. Why can’t marmots find enough food when they wake up?

A. Because there are too many marmots in the wild now.

B. Because plants haven’t received enough sunlight for spring growth.

C. Because winter days end much earlier than before.

D. Because more and more animal speci
