问题 The passage is mainly about ______ .
The main idea of the last paragraph is that ______ .
选项 A、most new ideas are, in fact, as old as hills.
B、it is the reduction to commercial practice that makes news and money
C、many of the original ideas behind TV originated earlier
D、Volkswagen rear engine car originated from a cart with the horse at the rear
答案A
解析 段落大意题。本段第一句就是主题句(topic sentence)，就是说如果一个人仔细研究专利和发明的话很快就会发现，其实很多新观点都跟山脉一样那么老了，也就是说许多新发明都是基于以前的许多旧观点。然后作者用了磁记录理论、电视机的发明、后引擎大众汽车等例子来说明这一点。因此A是正确答案。
