　　The food we eat seems to have profound 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 nto a new discovery. In 1945, about 35 years ago, government researchers realized that nitrates, commonly used to preserve color in meats,and other food additivies,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.

　　As the pace of life continues to increase ,we are fast losing the art of relaxation. Once you are in the habit of rushing through lift,being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body.

　　Stress is an natural part of everyday lift and there is no way to avoid it. In fact ,it is not the bad thing it is often supposed to be .A certain amount of stress is vital to provide motivation adn give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.

　　The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress,and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first signs of unusual difficulties. When exposed to stress,in whatever form,we react both chemically and physically. In fact we make choice between "fight" or "flight" and in more primitive days the choice made the difference between life or death. The crises we meet today are unlikely to be so extreme,but however little the stress,it involves the same response. It is when such a reaction lasts long,through continued exposure to stress,that health becomes endangered.Such serious conditions as high blood pressure and heart disease have established links with stress.Since we cannot remove stress from our lives(it would be unwise to do so even if we could),we need to find ways to deal with it.

　　1.People are finding less and less time for relaxing themselves because_____.

　　a.they do not know how to enjoy themselves

　　b.they do not believe that relaxation is important for health

　　c.they are travelling fast all the time

　　4.In Paragraph 3, "such a reaction" refers back to_______.

　　a."making a choice between 'flight' or 'fight'"

　　b."reaction to stress both chemically and physically"

　　c."responding to crises quickly"

　　d."losing heart at the signs difficulties"

　　In a country that defines itself by ideals, not by shared blood, who should be allowed to come work and live here? In the wake of the Sept. 11 attacks these questions have never seemed more pressing.

　　On Dec. 11, 2001, as part of the effort to increase homeland security, federal and local authorities in 14 states staged “Operation Safe Travel”—raids on airports to arrest employees with false identification (身份证明). In Salt Lake City there were 69 arrests. But those captured were anything but terrorists, most of them illegal immigrants from Central or South America. Authorities said the undocumented workers’ illegal status made them open to blackmail (讹诈) by terrorists.

　　Many immigrants in Salt Lake City were angered by the arrests and said they felt as if they were being treated like disposable goods.

　　Mayor Anderson said those feelings were justified to a certain extent. “We’re saying we want you to work in these places, we’re going to look the other way in terms of what our laws are, and then when it’s convenient for us, or when we can try to make a point in terms of national security, especially after Sept. 11, then you’re disposable. There are whole families being uprooted for all of the wrong reasons,” Anderson said.

　　If Sept. 11 had never happened, the airport workers would not have been arrested and could have gone on quietly living in America, probably indefinitely. Ana Castro, a manager at a Ben & Jerry’s ice cream shop at the airport had been working 10 years with the same false Social Security card when she was arrested in the December airport raid. Now she and her family are living under the threat of deportation (驱逐出境). Castro’s case is currently waiting to be settled. While she awaits the outcome, the government has granted her permission to work here and she has returned to her job at Ben & Jerry’s.

　　1. According to the author, the United States claims to be a nation ________.

　　A) composed of people having different values

　　B) encouraging individual pursuits

　　C) sharing common interests

　　D) founded on shared ideals

　　2. How did the immigrants in Salt Lake City feel about “Operation Safe Travel”?

　　A) Guilty.

　　B) Offended.

　　C) Disappointed.

　　D) Discouraged.

　　3. Undocumented workers became the target of “Operation Safe Travel” because ________.

　　A) evidence was found that they were potential terrorists

　　B) most of them worked at airports under threat of terrorists

　　C) terrorists might take advantage of their illegal status

　　D) they were reportedly helping hide terrorists around the airport

　　4. By saying “...we’re going to look the other way in terms of what our laws are” (Line 2, Para. 4), Mayor Anderson means “________”.

　　A) we will turn a blind eye to your illegal status

　　B) we will examine the laws in a different way

　　C) there are other ways of enforcing the law

　　D) the existing laws must not be ignored

　　5. What do we learn about Ana Castro from the last paragraph?

　　A) She will be deported sooner or later.

　　B) She is allowed to stay permanently.

　　C) Her case has been dropped.

　　D) Her fate remains uncertain.

　　There are two factors which determine an individual's intelligence. The first is the sort of brain he is born with. Human brains differ considerably, some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual—the sort of environment in which he is reared. If an individual is handicapped envionmentally ,it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable.

　　The importance of environment in determining an individual's intellingence can be demonstrated by the case history of the identical twins, Peter and Mark X. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old , their parents died, and they were placed in separate foster homes. Peter was reated by parents of low intelligence in an isolatedcommunity with poor educational pooprtunities.Mark was reared inthe home of well-to-do parents who had been to college. He was read to as a child , sent to good schools, and given every opportunity to be stimulated intellectually.This enviromental difference continued until the twins were in their late teens, when they were giben tesets to measure their intelligence. Mark's I.Q. was 125, twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities , the twins , having identical brains,would have tested at roughly the same level.

　　1.This selection can best be titled_________.

　　a.Measuring Your Intelligence

　　b.Intelligence and Environment

　　c.The Case of Peter and Mark

　　d.How the brain Influences Intelligence

　　2.The beststatement of the main idea of this passage is that _____.

　　a.human brains differ considerably

　　b.the brain a person is born with is improtant in determining his intelligence

　　c.environment is crucial in determining a person's intelligence

　　d. persons having identical brains will have roughly the same intelligence

　　3.According to the passage , the average I.Q.is _____.

　　a.85
