Children in the United States are exposed to many influences other than that of their families. Television is the most significant of these influences, because the habit of watching television usually begins before children start attending school.Parents are concerned about the lack of quality in television programs for children. The degree of violence in many of these shows also worries them. Studies indicate that, when children are exposed to violence, they may become aggressive or insecure.Parents are also concerned about the commercials (商业广告) that their children see on television. Many parents would like to see fewer commercials during programs for children. And some parents feel that these shows should not have any commercials at all because young minds are not mature enough to deal with the claims made by advertisers.Educational television has no commercials and has programs for children that many parents approve of. The most famous of these is Sesame Street, which tries to give preschool children a head start in learning the alphabet (字母) and numbers. It also tries to teach children useful things about the world in which they live.Even though most parents and educators give Sesame Street and shows like it high marks for quality, some critics argue that all television, whether educational or not, is harmful to children. These critics feel that the habit of watching hours of television every day turns children into bored and passive (被动的) consumers of their world rather than encouraging them to become active explorers of it1). Which of the following statements is not based on the passage?A. Parents are worried about the influence from television on their children.B. Television has much influence on children.C. Both parents and their children like watching educational television.D. Some critics think that television is no good for children.2). In what ways do children suffer from television?A. They become the victims of social violence.B. They spend hours watching television instead of doing school work.C. The programs make the children lose interest in the world.D. The programs make the children spend too much of their parents’ money.3). Parents would not like their children to see commercials because ______A. they think that their children are not old enough to handle advertisingB. commercials teach children alphabet and numbersC. commercials help to sell productsD. they don’t like commercials4). Educational television is widely appreciated because _____A. it does have the same commercials as othersB. it offers programs for both children and their parentsC. many parents like the programs it offers for their childrenD. children can learn some school subjects before they go to school5). Which of the following can best serve as the title of the passage?A. Watching Too Much Television Is Harmful to Young Minds.B. Television Is More Harmful than Educational.C.

Brain Drain1.Brain drain is a phenomenon under which"people of a nation move to another nation due to financial benefits and also due to economical reasons,but there are many more reasons behind it". If we think deeply to the topic,we would find that this phenomenon has more disadvantages than advantages.2.This phenomenon has many advantages for receiving countries which will automatically benefit from the skills and talents of immigrated people who were educated and qualified in their home countnes.3.However,developing countries are deeply affected by this phenomenon since they are deprived from millions of their skilled workers, doctors,hardworking Engineers,and billions of man power. Those elites represent the backbone of their economies and once they travel abroad,their economies will not flourish and promote.In fact,there are many reasons behind brain drain.Firstly,the Government is the first responsible for brain drain. The salaries paid by local companies are much less than multinational foreign companies,which pushes millions of intelligent,hardworking Engineers to leave their native countries to look for a better life and opportunities.Secondly,the status and facilities provided by foreign companies are much higher in quality and quantity.Also,some people find it a matter of pride and dignity to work as an employee in foreign countries.4.But we have to mention that brain drain does not only affect developing countries but also has some advantages for them.People living abroad help foreigners to know about their cultures and traditions.Also,they give information about various natural beauties and tourist spots in their home countries,which encourages tourists to visit them. This in turn increases tourist income.Brain drain also helps in increasing their foreign exchanges.5.But at last you would find that brain drain has more disadvantages than advantages on developing or poor countries.So,to stop brain drain,local governments should make people aware of its harmful effects.Also Government should provide opportunities to their elites and should provide them with handsome salary so that they can serve their own mother nation.This phenomenon has many advantages for receiving countries which will benefit from the skills and talents of______.A:its harmful effectsB:immigrated peopleC:the local governmentD:their cultures and traditionsE:the hardworking engineers F: in quality and quantity

第三篇Fight against the Side Effects of Cancer TreatmentOnce the hard decisions have been made about how to treat a patient's cancer,doctors face an even more difficult question:how do you help patients deal with the side effects of treatment?The issue is a challenge for physicians because,unlike with cancer therapies,there are few scientific studies on the most effective ways to handle the side effects一including common symptoms such as poor sleep or fatigue. But addressing these seemingly common complications（并发症）is crucial for helping patients maintain their regular lifestyle,which in turn may even encourage the success of their cancer treatment.That's why Dr. Karen Mustian of the University of Rochester Medical Center decided to put a favorite practice of cancer survivors一yoga一to the test.In a paper she will present at the American Society of Clinical Oncology (肿瘤学）(ASCO) annual meeting in June, Mustian designed a standardized program based on hatha yoga一a slow-moving form of the discipline一and tested its effect on improving the quality of life for cancer survivors.Called YOCAS,the four-week program involved sessions of hatha yoga twice a week for 75 minutes each,in combination with breathing exercises and meditation（冥想）.Among the 410 participants,who were divided into yoga and traditional follow一up care groups,those practicing yoga recorded nearly double the improvement in sleep quality and reduction of fatigue compared to those not practicing yoga. They also reported better quality of life overall,Mustian says.For cancer physicians,the findings will be a welcome addition to their discussions with patients."Many patients ask about complementary (互补的)therapies, whether they are exercise or meditation or yoga," says Dr. Douglas Blayney,medical director of the comprehensive cancer center at University of Michigan and president of ASCO."I often don't know what to tell them because there isn't lot of science on these complementary therapies. Here is a scientific study showing benefit,so at least we can have some assurance in telling women that there is a yoga program,here are its characteristics and it has been shown to have beneficial effects on sleep and quality of life."Mustian designed a standardized program________.A:to see whether yoga can reduce side effects of cancer treatmentB:to improve the quality of life for cancer patientsC:to popularize yoga among cancer survivorsD:to present it at the ASCO annual meeting

问答题Practice 1 Americans are proud of their variety and individuality, yet they love and respect few things more than a uniform, whether it is the uniform of an elevator operator or the uniform of a five-star general. 1______ 2______People have become conditioned to expect superior quality from a man who wears a uniform. The television repairman who wears uniform tends to inspire more trust than one who appears in civilian clothes. Faith in the skill of a garage mechanic is increased by a uniform. What easier way is there for a nurse, a policeman, a barber, or a waiter to lose professional identity(身份) than to step out of uniform? 3______They save on other clothes. They save on laundry bills. They are tax-deductible(可减税的). They are often more comfortable and more durable than civilian clothes. 4______Though there are many types of uniforms, the wearer of any particular type is generally stuck with it, without change, until retirement. When people look alike, they tend to think, speak, and act similarly, on the job at least. 5______Though they are long lasting, often their initial expense is greater than the cost of civilian clothes. Some uniforms are also expensive to maintain, requiring professional dry cleaning rather than the home laundering possible with many types of civilian clothes.[A] For this reason, more and more factories begin to give out uniforms to workers.[B] Why are uniforms so popular in the United States?[C] Uniform also have many practical benefits.[D] Uniform is also an indication of people’s position.[E] Among the arguments for uniforms, one of the first is that in the eyes of most people they look more professional than civilian clothes.[F] Primary among the arguments against uniforms are their lack of variety and the consequent loss of individuality experienced by people who must wear them.[G] Uniform also give rise to some practical problems.

问答题Practice 2 “To be a Negro in America is to hope against hope,” wrote Martin Luther King in the last year Of his life. The advance the black man in the United States, from the position of slave to that of proud and equal citizen, is slow. The black man’s hopes have often ended in despair. “Of the good things in life he has about one-half those Of whites；Of the bad he has twice those Of whites, ”wrote Dr. King. Half of all black people lived in poor houses. They’re received about half as much pay as whites. They had twice as many of their people out Of work and twice as many babies dead for lack Of proper care. Allowing for their numbers, twice as many black men as white fought in the war in Vietnam, and twice as many died in that war. Most black people sti11 did work that was unpleasant and poorly paid. That was the only work they could get.(from Great People of Our Time, ed., by Carol Christian Macmillan Education,1977)

单选题Passage1Lonely people, it seems, are at greater risk than the gregarious of developing illnesses associated with chronic inflammation, such as heart disease and certain cancers.A paper published last year in the Public Library of Science, Medicine, shows the effect on mortality of loneliness is comparable with that of smoking and drinking after examining the results of 148 previous studies and controlled for factors such as age and pre-existing illness.Steven Cole of the University of Califormia, Los Angeles, thinks he may know why this is so.He told the American Association for the Advancement of Science meeting in Washington,D.C., about his work studying the expression of genes in lonely people. Dr. Cole harvested samples of white blood cells from both lonely and gregarious people. He then analysed the activity of their genes, as measured by the production of a substance called messenger RNA. This molecule carries instructions from the genes telling a cell which proteins to make. The level of messenger RNA from most genes was the same in both types of people. There were several dozen genes, however, that were less active in the lonely, and several dozen others that were more active. Moreover, both the less active and the more active gene types came from a small number of functional groups.Broadly speaking, the genes less active in the lonely were those involved in staving off viral infections. Those that were more active were involved in protecting against bacteria. Dr. Cole suspects this could help explain not only why the lonely are iller, but how, in evolutionary terms, this odd state of affairs has come about.The crucial bit of the puzzle is that viruses have to be caught from another infected individual and they are usually species-specific. Bacteria, in contrast, often just lurk in the environment, and may thrive on many hosts. The gregarious are therefore at greater risk than the lonely of catching viruses, and Dr. Cole thus suggests that past evolution has created a mechanism which causes white cells to respond appropriately. Conversely, the lonely are better off ramping up their protection against bacterial infection, which is a bigger relative risk to them.What Dr. Cole seems to have revealed, then, is a mechanism by which social environment reaches inside a person's body and tweaks its genome so that it responds appropriately. It is not that the lonely and the gregarious are genetically different from each other. Rather, their genes are regulated differently, according to how sociable an individual is. Dr. Cole thinks this regulation is part of a wider mechanism that tunes individuals to the circumstances they find themselves in.What can we know about viruses and bacteria from the fourth paragraph?A
Viruses often remain hidden in the environment.B
Bacteria are passed to other people by the infected individual.C
The lonely people can catch viruses more easily.D
Viruses pose a greater threat to the gregarious than bacteria.
