4．What is the passage mainly about?

　　A．The beginning of road design.

　　B．The development of transport wheels.

　　C．The history of public transport.

　　D．The invention of fast­moving vehicles.

　　答案与解析

　　轮子是什么时候发明的呢？最早的用途又是什么呢？这些问题无人能回答。但是我们知道，轮子存在的时间已经超过5 500年。

　　1．C　细节理解题。由第二段第四句"This could be because animals did a perfectly good job of carrying farming tools and humans around."可知，动物在运载农具和人这一方面起了很重要的作用，这是轮子一时没有流行的原因。

　　2．D　细节理解题。由第三段最后一句"There had been no important changes in wheel and vehicle design before the arrival of modern road design."可知，在现代的道路设计之前，轮子和车辆的设计是没有重大变化的。故D项"道路设计为轮子设计的发展提供了条件"正确。

　　3．C　文章结构题。根据第四段中的"mid­1700s" "1820s" "1967"可知，整个段落是按时间顺序展开说明的。

　　4．B　主旨大意题。由文章全文内容尤其是第一段可知，本文主要介绍了轮子的发展，所以B项正确。
