正确答案: D
解析:
根据句子“from 72 percent in 1970 to 60 percent in 2002”可知,这里要填的是下降、下跌。decline下降,下跌。deteriorate使恶化。deduce推论。demolish毁坏,破坏;推翻。所以decline符合句意。

    本题主要考查open classrooms的定义。其意思是学校给学生提供一个活动的场所,学生可以做自己的事,老师的只是起监督作用而不负责传授知识。参考文章第二段末尾:孩子们在同一开放教室中进行许多不同的活动,而教师更多的是被看成敦促者而非知识的传播者。中学生有更多的机会自己决定选修什么课程,结果没有多少学生选修“外语和硬科学”。(注:硬科学指物理、化学、生物学、地质学等自然科学。)

    单选题
    "If there is one thing I’m sure about, it is that in a hundred years from now we will still be reading newspapers. It is not that newspapers are a necessity. Even now some people get most of their news from television or radio. Many buy a paper only on Saturday or Sunday. But for most people reading a newspaper has become a habit passed down from generation to generation. The nature of what is news may change. What basically makes news is what affects our lives-the big political stories, the coverage of the wars, earthquakes and other disasters, will continue much the same. I think there will be more coverage of scientific research, though. It’s already happening in areas that may directly affect our lives, like genetic (基因) engineering. In the future, I think there will be more coverage of scientific explanations of why we feel as we do-as we develop a better understanding of how the brain operates and what our feelings really are. It’s quite possible that in the next century newspapers will be transmitted (传送) electronically from Fleet Street and printed out in our own home. In fact, I’m pretty sure that how it will happen in the future. You will probably be able to choose from a menu, making up your own newspaper by picking out the things you want to read-sports and international news, etc. I think people have got it wrong when they talk about competition between the different media (媒体). They actually feed off each other. Some people once foresaw that television would kill off newspapers, but that hasn’t happened. What is read on the printed page lasts longer than pictures on a screen or sound lost in the air. And as for the Internet, it’s never really pleasant to read something just on a screen.In the writer’s opinion, in the future, ().
    A

    more big political affairs, wars and disasters will make news

    B

    newspapers will not be printed in publishing houses any longer

    C

    newspapers will cover more scientific research

    D

    more and more people will watch TV


    正确答案: C
