Passage 3

　　Within fifteen years Britain and other nations should be well on with the building of huge industrial complexes for the recycling of waste. The word rubbish could lose its meaning because everything which goes into the dustbin would be made into something useful. Even the most dangerous and unpleasant wastes would provide energy if nothing else.

　　The new concept of recycling waste is taking shape at the British technological laboratory at Warren Spring, not far from the north of London. Today, the laboratory spends four times as much money in studying recycling as it did five years ago.

　　The latest project is to take a city of around half a million inhabitants and discover exactly what raw materials go into it and what go out. The aim is to find out how much of these raw materials could be provided if a plant for recycling waste were built just outside the city. This plant would recycle not only metal such as steel, lead and copper, but also paper and rubber as well. Methods have been discovered, for example, for removing the ink from newsprint so that the paper can be used again, and for obtaining valuable oils and gases from old motor car types. All these ideas are already being made use of, but what is new is the idea of combining them on such a large scale in a single plant designed to recycle most types of waste.

　　Another new project is being set up to discover the best ways of sorting and separating the rubbish. When this project is complete, the rubbish will be processed like this： first, it will pass through sharp metal spikes which will tear open the plastic bags in which rubbish is usually packed； then it will pass through a powerful fan to separate the lightest elements from the heavy solids； after that crushers and rollers will break up everything that can be broken finally, and the rubbish will pass under magnets, which will remove the bits of iron and steel； finely the rubber and plastic will then be sorted out in the final stage.

　　The first full-scale giant recycling plants are, perhaps, fifteen years away. But in some big industrial areas, where rubbish has been dumped for so long that there are no holes left to fill up with rubbish, these new automatic recycling plants may be built sooner. Indeed, with the growing cost of transporting rubbish to more distant dumps, some big cities will be forced to build their own recycling plants before long.

　　Passage 4

　　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 from genetic conditions, and are severe enough to affect 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 expect to have such basic needs as food, shelter, and medical treatment. Unfortunately, these basics are often not available. Civil liberties such as the right to vote, marry, get an education, and gain employment have historically been denied on the basis of disability.

　　In recent decades, the disability rights movement has been organized to fight against these infringements of civil rights. Congress responded by passing major legislation recognizing people with disabilities as a 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 have that disabled people will be fully able to take their rightful place in society.

　　16. A “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. In the author's opinion, to enable the disabled people to take their rightful place in society.

　　A. more laws should be passed B. public attitudes should be changed C. government should provide more aids D. more public facilities should be set 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 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. Medical Treatments for Disabilities
