问题 The invention of irrigation is meaningful because it could help to
The passage is mainly about

选项 A、the relationship between climate change and civilization.
B、the history of global climate change.
C、the interaction between nature and human society.
D、the impact of the spread of agriculture.

答案A

解析 本题问文章的主旨是什么。文章首段提到农业中灌溉的发明"produced a sufficient surplus to feed the priests,scholars,artists and so on whose activities are collectively thought of as ’civilization’",接下来指出哺育文明的灌溉是由气候变化导致的;最后一段首句"So climate change helped to intensify agriculture,and thus start civilization"揭示了全文主题—气候变化导致文明产生。故"气候变化与文明的关系"正确。全球气候变化的历史:文章在第二、三段确实谈到了历史上曾经发生过的气候变化,但并非中心话题。自然界和人类社会的互动:本文主要谈论气候变化,"自然界"范围过宽。农业发展的影响:文中是提到了农业发展产生的一些影响,如末段中的毁林开荒等。但这只是本文的一项具体内容。
