问题 The best title for this text is ______. [br] We may infer from this passage that ______.

选项 A、carbon dioxide and CFCs are equally harmful to the environment.
B、global warming is a direct cause for natural disasters.
C、the world temperature rise has been going up more quickly as time passes.
D、people’s living standard has been on the rise.

答案 C

解析 本题询问从这篇文章中我们能推断出什么?根据原文(40)处可知,到了2030年,温度将升高1.3度,2070年将升高3度,所以随着时间的推移温度升高的速度会越来越快,C答案正确;第二段最后一句说到二氧化碳占温室效应的56%,而CFC占23%。所以二氧化碳更有害,A答案错;文中没提到自然灾害的问题,所以B答案错;D答案不是作者讨论的主题,故选C。
