英语四级听力短文理解模拟训练第17套

　　32．C主旨题。文章第一段引出现在一些大学的做法，即试行季节体制，第二段介绍该体制的优缺点，第三段义提到一些大学的折中做法，由此可知，全文都是对季节体制的介绍，所以C正确。

　　33．B信息明示题。第一段最后一句指出，三个学期分别在9月、1月和3月开始，暑期则是从6月到8月，由此可见，这种体制一共包括三个常规学期和一个暑期，所以B正确。

　　34．C信息明示题。文章第二段提到，这种体制的另外一个好处就是，尽管大多数学生在秋季开学，但在该体制下，学生也可以在其他任何学期开始的时候开始上课学习，所以C正确。

　　35．D信息明示题。文章最后一段最后一句提到，在这14周里，学校和学生都有足够的时间来学习并完成课程安排，所以D项有11周是错误的，故选D。

　　Section B

　　Passage One

　　People all over the world today are beginning to hear and learn more and more about the problem of pollution. Pollution is caused either by mans release of completely new and often artificial substances into the environment or by releasing greatly increased amounts of a natural substance, such as oil from oil tankers into the sea.

　　Whatever its underlying reasons, there is no doubt that much of the pollution caused could be controlled if only companies, individuals and governments would make more efforts. In the home there is an obvious need to control litter and waste. Food comes wrapped up three or four times in packages that all have to be disposed of; drinks are increasingly sold in bottles or tins which cannot be reused. This not only causes a litter problem, but also is a great waste of resources, in terms of glass, metal and paper. Advertising has helped this process by persuading many of us not only not to buy things we neither want nor need, but also to throw away much of what we do buy. Pollution and waste combine to be a problem everyone can help to solve by cutting unnecessary buying, excess use and careless disposal of the products we use in our daily lives.
