单选题 阅读下面这篇短文，短文后列出7个句子，请根据短文的内容对每个句子做出判断。如果该句提供的是正确信息，请选择A；如果该句提供的是错误信息，请选择B；如果该句的信息文章中没有提及，请选择C。 Pain is something that everyone experiences at some time, to a greater of lesser degree(在或大或小的程度) Chronic or long-term pain, however, is in a category(种类，范畴)of its own. This is the kind of pain that dominates and pervades(蔓延，渗透)the life of the sufferer. Relent- less(持续的), grinding, exhausting pain, from which there is no escape(无法逃避的). Most individuals who experience this kind of pain are paraplegics(截瘫患者)and tetrap1egics(四肢麻痹患者). These people, despite their disabilities, would often be capable of leading fulfilled and happy lives were it not for the fact(要不是/如果没有这一事实) that they suffer this terrible and debilitating(使衰弱)pain on an almost continuous basis. To date(到目前为止), treatment has been mainly in the form of heavy drug therapy, which produces unpleasant side effects. But there has been a breakthrough in pain control. A new device, SPES(Sub Perception Electro Stimulation) (不知觉电刺激), should radically (根本地) improve quality of life for many chronic pain sufferers. Professor I for Cape l, scientist and inventor, has conducted clinical trials of SPES on chronic pain sufferers with extremely encouraging results. SPES works by transmitting electrical signals controlled by microprocessors(微型信息处理机 ), in particular patterns across the brain, using tiny electrodes(电板) attached to the patient's earlobes. These signals stimulate chemical messages from the hypothalamus(下丘脑), the area of the brain which controls our bodily functions. As a result, a hormonal release is triggered, which alters the perception of pain. "The pain is still there", says Professor Cape l "but SPES helps you live with(接受某种局面)it. We are using .the body's natural ability to cope with pain." The treatment is painless and convenient, lasting for about an hour a day. The equipment is portable, so the person using it can move around comfortably. Other benefits are that it is non-addictive(不成瘾的) and the patient does not build up a tolerance(忍受)to SPES. It can be used at home without medical supervision. SPES should not, however, be used by pregnant women, epileptics(癫病患者), people who have pacemakers fitted(装上起搏器)and those who are taking certain prescribed drugs.

单选题In the United States, older people rarely live with their adult children. But in many other cultures children are expected to care (51) their aged parents. In some parts of Italy, the percentage of adult children who (52) with their parents reach 65 to 70 percent. In Thailand, too, children are expected to care for their elderly parents ;few Thai elderly live (53) . What explains these differences in living arrangements (54) cultures? Modernization theory (55) the extended family household to low levels of economic development. In traditional societies, the elderly live with their children in large extended family units for economic reasons. But with modernization, children move to urban areas, leaving old people behind in (56) rural areas. Yet modernization theory cannot explain why extended family households were never common in the United States or England, or why families in Italy, which is fully modemized, (57) a strong tradition of intergenerational living. Clearly, economic development alone cannot explain (58) living arrangements. Another theory associated intergenerational living arrangements with inheritance patterns. In some cultures, the stem family pattem of inheritance predominates. (59) this system, parents live with a married child, usually the oldest son, who then (60) their property when they die. The stem family system was once common in Japan, but changes in inheritance laws, as well as broader social changes brought (61) by industrialization and urbanization, have (62) the tradition. In 1960about 80 percent of Japanese over 65 lived with their children; by 1990 only 60 percent did - a figure that is still high (63) U.S. standards, but which has been (64) steadily. In Korea, too, traditional living arrangements are (65) : the percentage of aged Koreans who live with a son declined from 77 percent in 1984 to 50 percent just 10 years later. Although most elderly Koreans still expect to live with a son, their adult children do not expect to live with their children when they grow old.

单选题 下面有3篇短文，每篇短文后有5道题，每道题后面有4个选项。请仔细阅读短文并根据短文内容回答其后面的问题，从4个选项中选择1个最佳答案。{{B}}第一篇{{/B}} {{B}} Diseases of Agricultural Plants{{/B}} Plants, like animals, are subject to diseases of various kinds. It has been estimated that some 30,000 different diseases attack our economic plants; forty are known to attack com, and about as many attack wheat. The results of unchecked plant diseases are ail too obvious in countries that have marginal food supplies. The problem will soon be more widespread as the population of the world increases at its frightening rate. Even in countries that are now amply fed by thek agricultural products there could soon be food shortages. It is easy to imagine the consequences of some disastrous attack on one of the major crops; the resulting famines could kill millions of people, and the resulting hardship on other millions could cause political upheavals disastrous to the order of the world. Some plants have relative immunity to great many diseases, while others have a susceptibility to them. The tolerance of a particular plant changes as the growing conditions change. A blight may be but a local infection easily controlled; on the other hand it can attack particular plants in a whole region or nation. An example is the blight that killed virtually every chestnut tree in North America. Another is the famous potato blight in Ireland in the last century. As a result of that, it was estimated that one million people died of starvation and related ailments. Plant pathologists have made remarkable strides in identifying the pathogens of the various diseases. Bacteria may include invade a plant through an infestation of insect parasites carrying the pathogen. A plant can also be inoculated by man. Other diseases might be caused by fungus which attacks the plant in the form of a mold or smut or rust. Frequently such a primary infection will weaken the plant so that a secondary infection may result from its lack of tolerance. The symptoms shown may cause an error in diagnosis, so that treatment may be directed toward bacteria which could be the result of a susceptibility caused by primary virus infection.
