Recently some American scientists have given a useful sincere piece of advice to people in industrialized nations that they would be much healthier if they ate more of the same kind of food eaten by humans living more than 10,000 years ago. The scientists say that the human body has changed very little since humans first appeared on the earth, but the way we live has changed greatly. Our body has not been able to deal with these changes in life style and this has led to new kinds of sicknesses. These new sicknesses were not known in ancient times, so they are called “diseases of civilization”. Many cancers and diseases of the blood system, including heart attacks and strokes ( 中风 ) are examples of such diseases. Scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol or tobacco, probably none. Ancient people also got a great deal of physical exercise, but a change in food is one of the main differences between life in ancient times and that of today. Stone-age people hunted wild animals for their meat, which had much less fat than domestic or tame ones ( 家畜 ). They also ate a lot of fresh wild vegetables and fruits. They didn’t have milk or any other dairy products, and they made very little use of grains. But today, we eat a large amount of these. We eat six times more salt than our remote ancestors. We eat more sugar. We eat twice as much fat but only one third as much protein and much less vitamin C. People today probably do not want to live the way people thousands of years ago did, but scientists say that we would be much healthier if we ate much the same way as remote ancestors did, cutting the amount of fatty, salty and sweet food. 67. What is the main cause that people suffer from a lot of new sicknesses? A. Ancient people did a great deal of physical exercise. B. People today have a lot of alcohol. C. People today have more tobacco. D. Food today is quite different from that of ancient times. 68. Which of the following belongs to the dairy products? A. Milk B. Corn C. Pork D. Flour 69. New kinds of sicknesses have been found because ________. A. the human body has changed compared with humans who first appeared on the earth B. the way we live has changed a little C. our body can’t deal with the changes in life style D. the way we live today is proper for the human body 70. According to some scientists, Stone-age people were much healthier than people today because they ate a lot of ________. A. milk and other dairy products B. salt and sugar C. wild animals, fresh wild vegetables and fruits D. grain foods |

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.

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. The above 53 the main reasons for this problem, and therefore we have to 54 young people to be more active, as well as steering them away from fast food shops and 55 eating habits. 36.

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 meat can be shipped cheaply for long distances by railroads. 小题1: What’s the main topic of this passage?A.Food and religion. | B.Food and culture. | C.Nutrition of different foods. | D.Different ways of life. | 小题2:Which of the following statements is TRUE about food likes and dislikes?A.They are seldom related to nutrition. | B.They are mostly associated with people’s taste. | C.They are mostly connected with people’s life styles. | D.They are usually related to cultures or religions. | 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. | 小题5:Why do Americans prefer to eat beef?
