C
Cancer is among the top killer diseases in our society today and scientists have found out that stress（紧张） helps to bring it on．It is worthwhile to consider, therefore, what are the causes of stress in our life, and whether we can do anything about them．
Are we underemployed, or overburdened with too many responsibilities? Do we have a right balance of work and leisure（闲暇） in our lives? Are our relationships with family, friends or fellow workers all they should be?
All these things can be a cause of stress, and it is best to face them honestly, and bring our frustrations（沮丧，挫败） into the open．People who have a good row and then forget it are doing their health better than shoes who bottle up their feelings．[
If our self-examination has brought any causes of stress to light, let us consider what we can do about them．It is possible to change jobs．We can make more leisure and fill it more happily, if we will accept a different living standard．We can improve our personal relationships by a different attitude．It is we who allow other people to make ourselves unhappy．Often the little things that disturb us are not worth an hour’s anger．The teaching in the Bible “Don’t let the sun go down upon your wrath（愤怒）” is good advice from the health point of view as well as the religions（宗教，信仰）．
65．Which of the following statement is TRUE?

The food we eat seems to have a great effect on our health. Although science has made big steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of human illness is related to food and forty percent of cancer is related to food as well. That food is related to illness is not a new discovery. In 1945, some researchers realized that things commonly used to keep colour in meats and other food additives（添加剂）caused cancer.
Yet, these additives remain in our food, and it is difficult to know which things on the wrappings（包装）of foods are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to their animals, and because of this, penicillin has been found in the milk of cows. Sometimes similar things are supplied to animals not for their health, but just to make a profit.
The farmers are simply trying to fatten the animals in order to get a higher price on the market. Although some countries have tried to control such things, the practice continues.
According to this passage, we can know .
A. perhaps most of human illness is caused by what we eat
B. perhaps most kinds of cancer are related to what people eat
C. cancer was discovered in 1945
D. science has made food unfit to eat
Things that are used to keep colours in meats are .
A. harmful B. useless C. helpless D. dangerous
All the additives .
A. are bright and colourless
B. are not bright and colourful
C. have indirect effects on our health
D. have direct effects on our health
People use additives .
A. to make food more unfit to eat
B. to improve the colour and taste of the food
C. to change colour of the food
D. to take off the diseases of the food
Which of the following is not true?
A. Some wrappings of food are harmful.
B. Farmers try to make more money on the market by fattening their animals.
C. “The practice continues” means “things are still going on like that”.
D. We needn’t take care of what we eat.

Nuclear power's danger to health, safety, and even life itself can be described in one word; radiation(辐射).
Nuclear radiation has a certain mystery about it, partly because it cannot be detected (探测) by human senses. It can't be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can't detect them, sense them, without a radio receiver. Similarly, we can't sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.
At very high levels, radiation can kill an animal or human being completely by killing masses of cells in important organs (器官). But even the lowest levels can do serious damage. There is no level of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be significant. This is the case when only a few cells are hit, and if they are killed completely. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They reproduce themselves in an unusual way. They can grow into cancer. Sometimes this does not show up for many years.
This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the knowledge of the person at the time that damage has occurred. A person can be irradiated(放射治疗) and feel fine, then die of cancer five, ten, or twenty years later as a result. Or a child can be born weak or easy to get serious illness as a result of radiation absorbed by its grandparents.
Radiation can hurt us. We must know the truth.
According to the passage, the danger of nuclear power lies in __________.
A. nuclear mystery B. radiation detection
C. radiation level D. nuclear radiation
Radiation can lead to serious results even at the lowest level ________.
A. when it kills few cells B. if it damages few cells
C. though the damaged cells can repair themselves
D. unless the damaged cells can reproduce themselves
Radiation can hurt us in the way that it can _____.
A. kill large numbers of cells in main organs so as to cause death immediately
B. damage cells which may grow into cancer years later
C. affect the healthy growth of our younger generation
D. lead to all of the above results
Which of the following can be best inferred from the passage?
A. The importance of protection from radiation can be overemphasized (过分强调).
B. The mystery about radiation remains unsolved.
C. Cancer is mainly caused by radiation.
D. Radiation can hurt those who do not know about its danger.

Nowadays, the food we eat seems to have great effects on our health. Although science has made enormous steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well, especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures.
That food is related to illness is not a new discovery. In 1945, government researchers realized that nitrates, commonly used to preserve color in meats, and other food additives, caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and living animals, and because of this, penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration (FDA) has tried repeatedly to control these procedures, the practices continue.
1.What is the best possible title of the passage?
A. Drug and Food B. Food and Health
C. Cancer and Health D. Health and Drug
2.Which of the following statements is NOT true?
A. Some of the additives in our food are added to the food itself and some are given to the living animals
B. Researchers have known about the potential dangers of food additives for about sixty-eight years.
C. Drugs are always given to animals for medical reasons
D. Food may cause forty percent of cancer in world.
3.How has science done something harmful to mankind?
A. Because of science, diseases caused by polluted food have been virtually eliminated.
B. It has caused a lack of information concerning the value of food.
C. The scientists have preserved the color of meats, but not of vegetables.
D. Because of the application of science, some potentially harmful substances have been added to food.
4.What are nitrates used for?
A. They preserve the color of meats.
B. They preserve flavor in packaged foods.
C. They are the objects of research
D. They cause the animals to become fatter.

What will people die of 100 years from now? If you think that is a simple question, you have not been paying attention to the revolution that is taking place in bio-technology(生物技术). With the help of new medicine, the human body will last a very long time. Death will come mainly from accidents, murder and war. Today’s leading killers, such as heart disease, cancer, and aging itself, will become distant memories.
In discussion of technological changes, the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death. Cells(细胞) are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond l20 years because the basic materials of cells, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine to repair their organs ( The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on—in much the same way our bodies make new skin cells to take the place of old ones.)
It is exciting to imagine that the advance in technology may be changing the most basic condition of human existence, but many technical problems still must be cleared up on the way to this wonderful future.
1.According to the passage, human death IS now mainly caused by____.
A. diseases and aging B. accidents and war
C. accidents and aging D. heart disease and war
2.In the author’s opinion, today’s most important advance in technology lies in____.
A. medicine B. the Internet C. brain cells D. human organ
3.Humans may live longer in the future because_____.
A. heart disease will be far away from us
B. human brains can decide the final death
C. the basic materials of cells will last forever
D. human organs can be repaired by new medicine
4.We can learn from the passage that ______.
A. human life will not last more than 120 years in the future
B. humans have to take medicine to build new skin cells now
C. much needs to be done before humans can have a longer life
D. we have already solved the technical problems in building new cells
5.What will people in 2113 mainly die of /from?
A. Aging B. Accidents C. Cancer D. Heart disease

Since ancient times, people have known about its ability to reduce pain and high body temperature. More than 2000 years ago, the Greek doctor Hippocrates advised his patients to chew on the bark and leaves of the willow.
The tree contains a chemical called salicin（柳醇）. From salicin, researchers in the 1800s discovered how to make salicylic acid（酸）. And in 1897, a chemist named Felix Hoffmann at Friedrich Bayer and Company in Germany created acetyl salicylic acid. Later it became the active substance in a new medicine that Bayer called aspirin. The "a" came from acetyl. The "spir" came from the spirea plant, which also produces salicin. And the "in" Well, that is a common way to end medicine names.
In 1982, a British scientist shared the Nobel Prize in Medicine in part for discovering how aspirin works. Sir John Vane found that aspirin blocks the body from making natural substances called prostaglandins（前列腺素）.Prostaglandins have several effects on the body. Some cause pain and the expansion, or swelling（ 肿瘤; 膨胀）, of damaged tissue. Others protect the lining of the stomach and small intestine. Prostaglandins also make the heart, kidneys and blood vessels （血管）work well. But there is a problem. Aspirin works against all prostaglandins, good and bad. Scientists learned how aspirin interferes with an enzyme（酶）. One form of this enzyme makes the prostaglandin that causes pain and swelling. Another form of the enzyme creates a protective effect. So aspirin can reduce pain and swelling in damaged tissues. But it can also harm the inside of the stomach and small intestine（肠）.
1.What sickness can the medicine from the willow deal with according to the passage?
A. Cold B. Toothache C. Cancer D. Skin disease
2.What can we know about Prostaglandin according to the passage?
A. It results from pain.
B. It prevents the lining of the stomach and small intestine.
C. It causes blood vessels to work wrongly.
D. It is sometimes good but sometimes bad.
3.What can we know about aspirin according to the passage?
A. Aspirin can treat almost diseases.
B. Aspirin can create the protective enzyme.
C. Aspirin can harm the inside of the stomach and small intestine.
D. Aspirin can protect the inside of the stomach and small intestine.
