Many facts suggest that children are overweight and the situation is getting worse, according to the doctors. I feel there are 36 reasons for this.
Some people blame the fact 37   we are surrounded by shops selling unhealthy, fatty foods, _38 fried chicken and ice cream, 39 low price. This has turned out a whole generation of grown-ups 40 seldom cook a meal for themselves. If there 41 fewer of these restaurants, then probably children would buy less take-away food.
There is another argument that 42 parents for allowing their children to become overweight. I _43 this, because good eating habits begin early in life, long before children start to visit fast food shops. If children are given fried chicken and chocolate 44 healthy food, or are always allowed to choose 45 they eat, they will go for sweet and salty foods every time, and this 46 throughout their lives.
There is a third reason for this situation. Children these days 47 very little exercise. They do not walk to school. When they 48 home, they sit in front of 49 or their computers and play computer games. 50 is this an unhealthy pastime (消遣),it also gives them time to eat more 51 food. 52 they need is to go outside and play active games or sports.

When the school year starts, it can be difficult to get up early．After a few early mornings, extreme tiredness might make you feel like you’re going to fall over．The amazing thing is that you probably manage to stay awake all day long and into the night．But how?
A chemical in the brain called dopamine（多巴胺）might be part of the answer．According to new research, dopamine is what keeps people who don’t get enough sleep from conking out．The chemical also has a complicated influence on your ability to think and learn when you don’t get enough sleep．
To study sleep loss and its effect on the brain, scientists rounded up 15 healthy volunteers．The scientists tested each person’s memory and ability to pay attention twice: once after a good night’s sleep and once after being kept up all night long．During the tests, the scientists measured levels of dopamine in the brains of the volunteers．
The results showed that when the volunteers stayed up all night, dopamine levels increased in the brain．Higher levels of dopamine kept the volunteers awake even though they felt tired．Some people are amazingly able to think clearly and react quickly, even when they haven’t had much sleep．Other people have a really hard time paying attention when tired, and their reactions are slow．All of these may be related to the dopamine levels．However, the researchers found that higher levels of dopamine don’t remove the trouble people have thinking and learning while sleep-deprived （缺乏睡眠的）．
60．The underlined phrase “conking out” in the second paragraph probably means     ．
A．staying awake    B．falling asleep
C．paying attention         D．falling over
61．With a higher level of dopamine, one     ．
A．will not dream dreams at night              B．may have trouble in falling asleep
C．can still stay awake after staying up          D．can do better in learning and working
62．We can infer from the last paragraph that        ．
A．not all people can react quickly after they stay up late
B．dopamine in our brain does not work when we are sleeping
C．lack of sleep has no influence on one’s learning and thinking ability
D．the higher the dopamine levels are, the more quickly one reacts
63．The passage is developed by        ．
A．setting up a point and discussing it
B．giving examples and drawing a conclusion
C．pointing out similarities and differences
D．showing a fact and explaining the cause

We all have ideas about what kinds of foods are good to eat. We also have ideas about what kinds of foods are bad to eat. As a result, people from one culture often think the foods that people from another culture eat are nauseating(令人作呕的).When the famous boxer Muhammad Ali visited Africa, for example, one member of his group became quite sick when he saw someone pick up a butterfly and eat it. Many people would find it disgusting to eat rats, but there are forty-two different cultures whose people regard rats as appropriate food.
Food likes and dislikes do not always seem related to nutrition. For example, broccoli is first on a list of the most nutritious common vegetables, but it is twenty-first on a list of vegetables that Americans like most to eat. Tomatoes are sixteenth on the list of most nutritious vegetables, but they are first on the list of vegetables that Americans like most to eat.
But dislike is not the only reason why some cultures will not eat a certain food. In some cultures, certain foods are taboo. Some foods are taboo in certain religions, but there are also other food taboos that are not connected to a religion. We do not usually think about why certain things are taboo in our culture. We may not even know why they are taboo. Anthropologists(人类学家) try to discover the hidden reasons for taboos.
Anthropologists believe that most food likes and dislikes are a result of the ways of life of different people. Some people live in areas where there are both large animals and many insects. It is difficult for these people to kill large animals, and it requires a lot of energy. It is easier for them to use insects for food because it is not difficult to catch insects and it does not require a lot of energy. Nomadic(游牧的) people who move around will not want to keep pigs for food. People will not eat pets such as dogs. Americans eat a lot of beef because there is plenty of land for raising cattle and the me

at can be shipped cheaply for long distances by railroads.

小题3:The underlined word “taboo” (Line 3, Para. 3) refers to _____.

A．something undiscovered	B．certain religions
C．something forbidden	D．certain foods

小题4:What can we infer from the passage?

A．It is believed that brcoccoli is more nutritious than tomatoes.

B．Americans prefer tomatoes to beef.

C．People in Inner Mongolia would probably like to keep pigs for food.

D．The famous boxer Muhamm Ali would like to eat rat rather than butterfly.

C．Because they have the ideal condition to keep and ship cattle.

D．Because cattle are large animals.

Comprehensive lifestyle changes including a better diet and more exercise can lead not only to a better physique, but also to swift and dramatic changes at the genetic level, U.S. researchers said on Monday. In a small study, the researchers tracked 30 men with low-risk prostate cancer（前列腺癌）who decided against conventional medical treatment such as surgery and radiation or hormone therapy.

The men underwent three months of major lifestyle changes, including eating a diet rich in fruits, vegetables, whole grains, legumes and soy products, moderate exercise such as walking for half an hour a day, and an hour of daily stress management methods such as meditation（冥想）. As expected, they lost weight, lowered their blood pressure and saw other health improvements. But the researchers found more profound changes when they compared prostate biopsies taken before and after the lifestyle changes. After the three months, the men had changes in activity in about 500 genes -- including 48 that were turned on and 453 genes that were turned off. The activity of disease-preventing genes increased while a number of disease-promoting genes, including those involved in prostate cancer and breast cancer, shut down, according to the study published in the journal Proceedings of the National Academy of Sciences.

The research was led by Dr. Dean Ornish, head of the Preventive Medicine Research Institute in Sausalito, California, and a well-known author advocating lifestyle changes to improve health. "It"s an exciting finding because so often people say, "Oh, it"s all in my genes, what can I do?" Well, it turns out you may be able to do a lot," Ornish, who is also connected with the University of California, San Francisco, said in a telephone interview. ""In just three months, I can change hundreds of my genes simply by changing what I eat and how I live". That"s pretty exciting," Ornish said. "The implications of our study are not limited to men with prostate cancer."

60. The article basically states that a healthy lifestyle__________.

A. can even change your genes for the better.

B. has no effect on your genes.

C. is good for the environment.

D. helps men recover from prostate cancer.

61. Apart from eating healthy food and exercising, the men in the study__________.

A. were put under a lot of stress.

B. were walking for hours a day..

C. were taught stress management methods.

D. were thinking for a whole day.

62. In total, how many disease-preventing genes turned on as a result of the healthy lifestyle?

A. 30 B. 453 C.500 D. 48

63. Which of the following is NOT mentioned in the article?

A. The men with low-risk prostate in the study lost weight and lowered their blood pressure.

B. A famous author and Dr. Dean Ornish led this research.

C. Dr. Dean Ornish expressed his optimism about this research in a telephone interview.

D. Conventional medical treatment has no effect on the men with prostate cancer.
