Questions 1 to 5 are based on the following passage: Some years ago the captain of a ship was very interested in medicine.

The fact that a child picks a language 63 is 64 : At one year old, a child is able to say “bye-bye”; at two, he is able to use fifty; by there he begins to 65 tenses.

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.
