问题 Farming emerged as a survival strategy because man had been obliged ______.
The message the author wishes to convey in the passage is that ______.
选项 A、human civilization remains gorious though it is affected by climatic changes
B、mankind is virtually helpless in the face of the dramatic changes of climate
C、man has to limit his activities to slow down the global warming process
D、human civilization will continue to develop in spite of the changes of nature
答案C
解析 本文作者的主要观点为：地球变暖是地球气候周期性变化过程的一部分，是由地质因素和气象因素导致的，与人类活动无必然关系。但由全文最后一句推理，作者并来排除人类活动对地球变暖有影响的论断。由此分析，作者想表达这样一个信息：人类虽不能扭转全球变暖的过程，但可以有所作为，减缓这一过程。
