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 norma
l 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.
1.Fruit flies were used in the research because_______.
A. they are very easy to catch B. they are fond of eating apples
C. they can live longer than before D. they share similar genes with humans
2.By studying the diets of many women, researchers _______.
A. found they are healthier than men
B. helped them lose weight successfully
C. discovered the genetic code of the apple
D. proved apples were good for people’s health
3.From the story, we can infer that _____.
A. scientists are studying new types of apples
B. apples’ genetic code is similar to other fruits
C. women like to eat apples more often than men
D. people who eat apples are protected from heart disease

“An apple a day keeps the doctor away.” Similarly, if we drink a little more water every day, we may find that we need to go to the doctor a lot less often. A healthy diet is made up of water and a great many different kinds of foods. We know that healthy foods like fruits, vegetables and fish, are important as they provide us with energy and fiber, without giving us too much fat and sugar. But why is water important?
The human body needs water to survive. Water is important as it carries poisons and waste out of our bodies. However, doctors advise us to drink plenty of water, much more than the small amount we need to stay alive.
Some doctors believe that water is important for our health in all kinds of ways. They believe that a great many illnesses and health problems appear as a result of dehydration--a lack(缺少) of water in the body. Most people are dehydrated at least some of time, although they probably don’t know it. It is surprising to learn that if we feel thirsty, we are already in the first stages of dehydration. In fact, we are advised to drink water before we feel thirsty.
These doctors think that health problems such as headaches, high blood pressure and asthma could be helped if people drink more water. They also believe that drinking more water can help people who are overweight. Water contains no calories so it will not make us put on weight. If we drink water, we will probably drink less sugary soft drinks such as Coca-cola. Doctors also believe that drinking more water may stop people from overeating. They say that many people think that they are hungry when they are, in fact, thirsty. Doctors suggest, therefore, that we eat less food and drink more water.
There are still many health problems that cannot be solved by drinking water, so we should not stop going to seeing the doctor completely. However, if we make a decision to drink water every day, we may find that we need to go to the doctor a lot less often.
1.We need _____for a healthy diet.
A. fibre B. Water and different foods

2.From the text, we know water can carry_________.
A. energy and fibre in our bodies
B. fruit, vegetables and fish in our bodies
C. poisons and waste out of our bodies
D. sugar and fat out of our bodies
3.Lack of water caused people to put on weight too much because_______.
A. it makes them hungry
B. they think they are thirsty and eat less
C. water has no calories
D. they think they are hungry and eat too much
4.Which of the following isn’t mentioned in the passage?
A. The amount of water a person should drink in a day.

A small piece of fish each day may keep the heart doctor away. That’s the finding of a study of Dutchmen in which deaths from heart disease were more than 50 percent lower among those who consumed at least an ounce of salt water fish per day compared to those who never ate fish.
The Dutch research is one of three human studies that give strong scientific support to the long-held belief that eating fish can provide health benefits, particularly to the heart. Heart disease is the number-one killer in the United States, with more than 550,000 deaths occurring from heart attacks each year. But previous research has shown that the level of heart disease is lower in cultures that consume more fish than Americans do. There are fewer heart disease deaths, for example, among the Eskimos of Greenland, who consume about 14 ounces of fish a day, and among the Japanese, whose daily fish consumption average more than 3 ounces.
For 20 years, the Dutch study followed 852 middle-aged men, 20 percent of whom ate no fish. At the start of the study, average fish consumption was about two-thirds of an ounce each day, with more men eating lean fish than fatty fish.
During the next two decades, 78 of the men died from heart disease. The fewest deaths were among the group who regularly ate fish, even at levels far lower than those of the Japanese or Eskimos. This relationship was true regardless of other factors such as age, high blood pressure, or blood cholesterol levels.
1.The passage is mainly about ________.
A．the high incidence of heart disease in some countries
B．the changes in people’s diet
C．the daily fish consumption of people in different culture
D．the effect of fish eating on people’s health
2.We can infer from the passage that there are fewer heart disease deaths ________.
A．in the countries of the yellow-skin race
B．in the countries with high consumption of fish
C．in the countries with good production of fish
D．in highly-developed countries
3.The underlined part “This relationship” may refer to the connection between ________ and the level of heart disease.
A．regular fish-eating B．the kind of fish eaten
C．the amount of fish eaten D．people of different areas
4.In which section of a newspaper can we read this passage?
A．Ads. B．Movies. C．Health and Diet. D．Briefs.

A small piece of fish each day may keep the heart doctor away. That’s the finding of a study of Dutch men in which deaths from heart disease were more than 50 percent lower among those who consumed (消耗) at least an ounce (盎司) of salt water fish per day compared to those who never ate fish.

Heart disease is the number-one killer in the United States, with more than 550,000 deaths occurring from heart attacks each year. But long before researchers have noticed that the incidence (发生率) of heart disease is lower in cultures that consume more fish than Americans do.
