You may know the saying: An apple a day keeps the doctors away. A recent study by the Chinese University of Hong Kong has discovered another saying: An apple a day keeps old age away.

The study involved fruit flies, as they share many genes with humans. Researchers gave one group of fruit flies normal food, and another group of fruit flies got the same food including apple.

The results showed that flies that ate apple lived an average of 55 days longer than the flies that didn’t eat apple. The study also found that apple-eating flies were more able to walk, climb and move about as they became old, the Journal of Agricultural and Food Chemistry reports.

The researchers believe that the antioxidants (抗氧化剂) found in apples are good for health.

In another experiment, researchers studied the diets of thousands of women. They found that those women who often ate apples were 20 percent less likely to have a heart attack.

Scientists have recently discovered the apple’s genetic code. This allows scientists to make new kinds of fruit that are healthier. Researchers are already using this information to grow apples with added antioxidants. Antioxidants help to keep eyes and joints (关节) healthy and protect against heart attacks and cancer.

Apples that help people lose weight may be in supermarkets in just four or five years. They are said to be “extra healthy” apples that can stop people from overeating.

If a noisy neighbor is blasting music at all hours of the day and night, drowning out your phone conversations and interrupting your sleep, you can call the police. But what is a whale to do?

Natural noise from waves, wind, rain and even earthquakes is common in oceans. Unfortunately, man?made noise from oil and gas drilling, sonar, and ships is also present.

Low frequency noise has doubled off the California coast every decade since the nineteen sixties. The main reasons are ships' propellers (螺旋桨). They not only generate continuous low frequency sound, some propellers cavitate(形成气穴), which means they create air bubbles that collapse, creating loud popping sounds.

Whales use low frequency calls to communicate across thousands of miles of ocean. They are threatened by noise pollution because it can prevent them from contacting each other and from locating their foods. Endangered humpback and right whales, which use fibrous baleen to strain food from the water, are the most at risk.

Scientists studying right whales off Canada's east coast have discovered that whales are sending louder calls through the water to make themselves heard. Because they invest more energy in making calls, they have less energy available for finding food and mating. Other scientists measuring whale calls against background noise pollution have discovered that right whales have lost about eighty percent of their normal communication area. This could seriously affect survival of this already threatened species.

Scientists don't have badges and guns, but they are trying to correct the noise pollution problem. By tracking ships and marine mammals and understanding how noise travels, they are creating sound maps. They hope to get shipping lanes moved so that the noise pollution ships create will not overlap with areas most important to the whales.

1.What does the passage mainly talk about?

A. Whales are in danger because of the noise.

B. Noise pollution is affecting whales.

C. Natural noise is good for whales.

D. How to protect whales endangered.

2.The following statements are true EXCEPT ________.

A. You can call the police if you are disturbed by a noisy neighbor.

B. Low frequency noise has doubled off the Canadian coast every decade since the 1960s.

C. Noise pollution can prevent whales from contacting each other and from locating prey.

D. Endangered humpback and right whales are the most at risk.

3.We can infer from the last paragraph that ________.

A. some areas important to whales are overlapped with the ship lanes

B. scientists are creating the sound maps by tracking ships and marine mammals

C. if scientists have guns, they can correct the noise pollution

D. scientists have worked out a plan to protect the whales

4.According to scientists,________.

A. right whales off the Californian coast have been in danger because of the loss of the energy

B. right whales cannot find food and mate for they lose a lot of living area

C. there are about 20% of the normal communication areas still available for the right whales

D. the right whales always invest most of their energy for making calls
