Mental Retardation (智力迟钝)Mental retardation is a condition in which people have lower than normal intelligence and are unable to function at the level expected for their age. People with mental retardation are usually born with it, or it develops early in their life. They may also have some difficulty with daily living skills such as learning to read and write and caring for themselves.Doctors and other professionals determine that a person has mental retardation based on their intelligence and how well they can do everyday activities. Intelligence is the ability to learn and understand Levels of intelligence are measured by special tests called intelligence tests. The score a person gets on one of these tests gives a numerical (数字的) measure of a person’s intelligence. This is called an intelligence quotient (智商) or IQ.An average score on an IQ test is about 90 to 110. a person with mental retardation will usually score below 75 on an IQ test.The IQ test alone does not determine whether someone is mentally retarded a person must also have trouble with everyday activities such as getting dressed, eating, washing, or learning basic reading, writing, and arithmetic skills.Mental retardation is not a disease itself. It cannot be cured and it’s not contagious (传染的). This condition can be caused by several things that injure the brain or don’t allow the brain to develop normally. Many times we don’t know why a person has mental retardation.Sometimes it may be caused by genes. Genes are chemical units found in every cell. They carry the instructions telling cells what to do. Sometimes, children receive abnormal genes from their parents.a defective gene may also develop spontaneously. Neither parent would have passed on the gene, but the gene changes before the baby develops;Some other problems that can cause mental retardation also happen before a child is born. It is important for the brain to develop properly if a child is to have normal intelligence. "Planning a pregnancy is the most important decision most of us will make in our lifetime. A healthy lifestyle and good medical care should begin before a woman becomes pregnant and continue throughout the pregnancy," says Jodi Rucquoi, a genetic counselor from Connecticut. If a woman abuses alcohol or drugs or doesn’t eat well, there is a risk to the developing baby. Also, a premature birth or problems during childbirth can sometimes harm the baby’s developing brain. While premature babies are generally fine, there is a greater chance that they may have mental retardation.In some cases, a young child can develop mental retardation after being sick with a serious infection or other illness, or after suffering a bad head injury. a child can be taken as mentally retarded if he or she()

Passage Two In only two decades Asian Americans have become the fastestgrowing the U. S. minority. As their children began moving up through the nation’s schools, it became clear that a new class of academic achievers was emerging. Their achievements are reflected in the nation’s best universities, where mathematics, science and engineering departments have taken on a decidedly Asian character. This special liking for mathematics and science is partly explained by the fact’ that Asian-American students who began their educations abroad arrived in the U.S. with a solid grounding in mathematics but little or no knowledge of English. They are also influenced by the promise of a good job after college. Asians feel they will be judged more objectively. And the return on the investment in education is more immediate in something like engineering than with an arts degree. Most Asian-American students owe their success to the influence of parents who are deter- mined that their children take full advantage of what the American educational system has to offer. An effective measure of parental attention is homework. Asian parents spend more time with their children than American parents do, and it helps. Many researchers also believe there is something in Asian culture that breeds success, such as ideals that stress family values and emphasize education. Both explanations for academic success worry Asian Americans because of fears that they feed a typical racial image. Many can remember when Chinese, Japanese and Filipino immigrants were the Victims of social isolation. Indeed, it was not until 1952 that laws were laid down giving all Asian immigrants the right to citizenship. Why do the two "explanations" (Line 1, Para. 3) worry Asian Americans（）

Passage Four When I began reading Catch-22, I thought it was a farcical satire on life in the’ United States Army Air Force. Later I believed that Mr. Heller’s target was modern war and all those who axe responsible for waging it. Still later it seemed that he was attacking social organization and anyone who derives power from it. But by the end of the book it had become plain to me that it is no other phrase will do the human condition itself which is the object of Mr. Heller’ an outraged fury and disgust. A reviewer must always keep an anxious eye on the state of his currency. If he announces too many masterpieces he risks inflation (though it is sometimes forgotten by some of us that the cowardice of perpetual crabbing (挑剔) receives its own kind of punishment). It does not seem many weeks since I was proclaiming that Malcolm Lowry’s Under the Volcano is one of the great English novels of the century; and not long before that I was urging that attention should be paid to the magnificent and neglected talent of William Gerhardi. But at the risk of inflation I cannot help writing that Catch-22 is the greatest satirical work in English since Erewhon. For the fact is that all my successive interpretations of this book now seem to have been accurate, even if the earlier ones were also incomplete. The book has an immense and devastating (讽刺的) theme, but this theme is illustrated, as it should be, by means of an observed reality. I am not suggesting that Catch - 22 is a realistic account of life in the war——time Air Force of America or any other country. The method of satire is to inflate (放大) reality so that all its partially concealed blemishes (缺点) turn into monstrous and apparent deformations. The effect of good satire is to make us laugh with horror. And this means that social and person- al evils which are being satirized must have been there, and must be felt by the reader to be there even while he is laughing at the results of the satirist’s inflating imagination. The underlined part "keep an anxious eye on the state of his currency" means （）

People may get anthrax if they are exposed to anthrax (57) But here’s the important part：just being exposed to these spores doesn’t mean that a person will get (58) .For a person to get sick, he would have to breathe in thousands of these spores all the way Into his (59) .
