People with disabilities comprise a large part of the population. It is estimated that over 35 million Americans have physical, mental, or other disabilities. About half of these disabilities are “developmental”, i. e. , they occur prior to the individual’s twenty-second birthday, often form genetic conditions, and are severe enough to effect three or more areas of development, such as mobility, communication, employment, etc. Most other disabilities are considered “adventitious”, i.e. , accidental or caused by outside forces. Prior to the 20th century, only a small percentage of people with disabilities survived for long. Medical treatment for these disabilities was unavailable. Advancements in medicine and social services have created a climate in which people with disabilities can expert to have such basic needs as food, shelter, and medical treatment. Unfortunately, these basic are often not available. Civil liberties such as the right to vote, marry, get an education, and again employment have historically been denied on the basic of disability. In recent decades, the disability rights movement has been organized to flight against these infringements (侵害) of civil rights. Congress responded by passing major legislation recognizing people with disabilities as protected class under civil rights statutes. Still today, people with disabilities must fight to live their lives independently. It is estimated that more than half of qualified Americans with disabilities are unemployed, and a majority of those who do work are underemployed. About two-thirds live at or below the official poverty level. Significant barriers, especially in transportation and public awareness, prevent disabled people from taking part in society. For example, while no longer prohibited by law from marrying, a person with no access to transportation is effectively excluded from community and social activities which might lead to the development of long-term relationships. It will only be when public attitudes advance as far as laws are that disabled people will be fully able to take to their right place in society. 16. ”developmental” disability . A. develops very slowly over time B. is caused forces C. occurs in youth and affects development D. is getting more and more severe 17. Most disabled people used to die early because . A. disabilities destroyed major bodily functions B. they were not very well looked after C. medical techniques were not available D. they were too poor to get proper treatment 18.

A. more laws should be passed B. public attitudes should be changed C. government should provide more aids D. more public facilities should be act up 19. Which of the following cannot be inferred from the passage? A. Many disabled people may remain single for their whole life. B. The public tends to look down upon the disabled people. C. The disabled people feel inferior to those surrounding them. D. Discriminatory (有差别的) laws prevent the disabled from mixing with others. 20. The best title for this passage might be . A. Handicaps of People with Disabilities B. The Difficulties of the Disabled C. The Causes for Disabilities D.

Passage 2 Questions 6 to 10 are based on the following passage: There are two kinds of memory: shot-term and long-term. Information in long-term memory can be remembered at a later time when it is needed. The information may be kept for days or weeks. However, information over and over. The following experiment shows how short-term memory has been studied. Henning studied how students who are learning English as a second language remember vocabulary. The subjects in his experiment were 75 college students. They represented all levels of ability in English: beginning, intermediate, and native-speaking students. To begin, the subjects listened to a recording of a native speaker reading a paragraph in English. Following the recording, the subjects took a 15-question test to see which words they remembered, each question had four choices. The subjects had to circle the word they had heard in the recording. Some of the questions had four choices that sound alike. For example, weather, whether, wither, and wetter are four words that sound alike. Some of the questions had four choices that have the same meaning. Method, way, manner, and system would be four words with the same meaning. Finally the subjects took a language proficiency test. Henning found that students with a lower proficiency in English made more of their mistakes on words that sound alike; students with a higher proficiency made more of their mistakes on words that have the same meaning. Henning’s results suggest that beginning students hold the sound of words in their short-term memory, and advanced students hold the meaning of words in their short-term memory. 6. Henning made the experiment in order to study . A. how students remember English vocabulary by short-term memory B. how students learn English vocabulary C. how to develop students’ ability in English D. how long information in short-term memory is kept 7. Which of the following statements is TRUE according to the passage? A. Information in short-term memory is different from that in long-term memory. B. Long-term memory can be achieved only by training. C. It is easier to test short-term memory than long-term memory. D. Henning gave a separate test on vocabulary to his students. 8. From Henning’s result we can see that . A. beginners have difficulty distinguishing the pronunciation of words B. advanced students remember words by their meaning C. it is difficult to remember words that sound alike D. it is difficult to remember words that have the same meaning 9. The word “subjects” in the passage means . A. memory B. the theme of listening material C. a branch of knowledge studied D. the students experimented on

The tourist trade is booming. With all this coming and going , you'd expect greater understanding o develop between the nations of the world. Not a bit of it ! Superb systems of communication by air, sea and land make it possible for us to visit each other's countries at a moderate cost. What was once the 'grand tour' , reserved for only the very rich , is now within everybody's grasp ? The package tour and chartered flights are not to be sneered at. Modern travelers enjoy a level of comfort which the lords and ladies on grand tours in the old days couldn't have dreamed of. But what's the sense of this mass exchange of populations if the nations of the world remain basically ignorant of each other? Many tourist organizations are directly responsible for this state of affairs. They deliberately set out to protect their clients from too much contact with the local population. The modern tourist leads a cosseted, sheltered life. He lives at international hotels , where he eats his international food and sips his international drink while he gazes at the natives from a distance. Conducted tours to places of interest are carefully censored. The tourist is allowed to see only what the organizers want him to see and no more. A strict schedule makes it impossible for the tourist to wander off on his own ; and anyway, language is always a barrier, so he is only too happy to be protected in this way. At its very worst , this leads to a new and hideous kind of colonization. The summer quarters of the inhabitants of the cite universitaire : are temporarily reestablished on the island of Corfu. Blackpool is recreated at Torremolinos where the traveler goes not to eat paella, but fish and chips. The sad thing about this situation is that it leads to the persistence of national stereotypes. We don't see the people of other nations as they really are, but as we have been brought up to believe they are. You can test this for yourself. Take five nationalities , say, French, German, English, American and Italian. Now in your mind, match them with these five adjectives : musical, amorous, cold, pedantic, native. Far from providing us with any insight into the national characteristics of the peoples just mentioned , these adjectives actually act as barriers. So when you set out on your travels, the only characteristics you notice are those which confirm your preconceptions. You come away with the highly unoriginal and inaccurate impression that , say,'Anglo-Saxons are hypocrites' of that 'Latin peoples shout a lot'. You only have to make a few foreign friends to understand how absurd and harmful national stereotypes are. But how can you make foreign friends when the tourist trade does its best to prevent you ? Carried to an extreme, stereotypes can be positively dangerous. Wild generalizations stir up racial hatred and blind us to the basic fact 〞how trite it sounds ! 每 That all people are human. We are all similar to each other and at the same time all unique. 1. The best title for this passage is [A] Tourism contributes nothing to increasing understanding between nations. [B] Tourism is tiresome. [C] Conducted tour is dull. [D] Tourism really does something to one's country. 2. What is the author's attitude toward tourism ? [A] apprehensive. [B]negative. [C] critical. [D] appreciative. 3. Which word in the following is the best to summarize Latin people shout a lot? [A] silent. [B] noisy. [C] lively. [D] active. 4. The purpose of the author's criticism is to point out [A] conducted tour is disappointing. [B]the way of touring should be changed. [C] when traveling , you notice characteristics which confirm preconception. [D] national stereotypes should be changed. 5. What is 'grand tour' now ? [A] moderate cost. [B]local sight-seeing is investigated by the tourist organization. [C] people enjoy the first-rate comforts. [D] everybody can enjoy the 'grand tour'
