请开始答题:

按照惯例,北华工商管理学院每年一度的特等奖学金获得者的名额仅3名,奖金数额高达10000元。1998年,该校董事会关于评定本年度特等奖学金确定了如下的原则:只有连续3年获得过三等奖以上的奖学金并且本年度各门学科终考成绩平均得分在90分以上的,方可获该项特等奖学金。但评选的结果表明,校董事会确定的上述原则并没有得到严格的贯彻。
以下哪项如果为真,最能支持上述结论

A.1998年度北华工商管理学院学生的各科终考成绩的平均得分都在90分以下

B.张三于1997年入学,他以本年度各科终考平均得分95分的优异成绩获1998年度特等奖学金

C.李四连续3年获得三等奖以上的奖学金并且本年度各学科终考成绩平均得分在90分以上,但没有获得本年度的特等奖学金

D.1998年度北华工商管理学院实际评定的特等奖学金获得者的名额为6名.每名的奖金数额下降为5000元

答案

参考答案:B

解析: 加强型题目,考查了复言命题的推理规则。“只有连续3年获得过三等奖以上的奖学金并且本年度各门学科终考成绩平均得分在90分以上的,方可获该项特等奖学金”是一个必要条件假言命题,要支持结论“上述原则并没有得到严格的贯彻”,指出该命题为假即可,必要条件假言命题当前件假且后件真时为假。A项说明前件假,但没有指明后件是否为真,故不能支持结论;B项张三没有连续三年获得过三等奖以上奖学金,符合前件假且后件真的情况,故支持了结论;C项是前件真且后件假的情况,不能支持结论;D项否定的是惯例,与这一原则无关,也不能支持结论。故选B。

In today’s world, almost everyone knows that air pollution and water pollution are harmful to people’s health. However, not all the persons know that noise is also a kind of pollution, and that is harmful to human health, too.

People who work and live under noisy conditions usually become deaf. Today, however, scientists believe that 10 percent of workers in Britain are being deafened by the noise where they work. Many of the workers who print newspapers and books, and who weave(织) cloth become deaf. Quite a few people living near airports also become deaf. Recently it was discovered that many teenagers in America could hear no better than 65-year-old persons, for these young people like to listen to pop music and most of pop music is a kind of noise. Besides, noise produced by jet planes or machines will make people’s life difficult and unpleasant, or even make people ill or even drive them mad.
