单选题 What can we conclude from the passage?

A、 A rise in global temperature less than 1℃ is unlikely to cause enormous lifestyle changes.
B、 Global warming would affect many things such as agriculture and people' s life.
C、 Global warming would lead to rise in the sea level directly.
D、 The overwhelming majority share Professor Wong' s prediction.

【正确答案】 B

【答案解析】[解析]推理判断题。根据文章第二段最后一句"Even more disturbing was．．．their lives would be directly affected...the next 20 years．”以及后面三到五段的内容可总结出：全球变暖将会对人类的生活、生产等方面造成巨大的影响和可怕的后果，故B)为正确答案。[避错指导]A)项与第三段最后一句内容相反，故排除；根据第四段首句“Primary．．．the rise in sea level as a result of the melting of the polar icecaps”(这些变化中最主要的就是由于极地冰盖的融化而造成的海面上升)可排除C)；第四段最后一句提到Wong教授的预测招来了许多争论，由此排除D)。
