Dear Editor,
Recently we have made a discussion about the prevent of global warming in our research
group. Everybody has become aware the green-house effect, what has drawn the attention of the world. Many scientists on the summit of COPENHAGEN warned any rise above 2 degrees could lead to a sea level rise threatening islands and coastal cities, kill off many specie of animals and plants. As a result of, every nation should work together to limit the release of carbon dioxide. Everybody should shoulder the responsible for fight against climate change, and a low carbon life is a must.
I think fight against global warming is part of environmental protection. If we humans are more friend to nature, nature will be friendly, too. It’s time everybody rethink our role in keeping peace with our mother, nature.
Yours sincerely,
Lihuaprevent—prevention
答案：
(答案→)prevent—prevention
解析：
【小题1】prevent—prevention介词about后面要接名词形式，故使用prevention。
【小题2】aware ^ of固定搭配be/become aware of意识到。。。。
【小题3】 what —which本句是一个定语从句，which指代先行词the green-house effect在句中作主语。What不能引导定语从句。
【小题4】kill —killing本句的killing是现在分词在句中作结果状语，表示的是正常的意料之中的结果。
【小题5】specie —species前面有many修饰，说明这里要使用复数形式。
【小题6】result of—result如果使用as a result of…（因为）后面要有宾语的形式。As a result结果是。表示上下文的因果关系。
【小题7】responsible – responsibility本句中的responsibility作为动词shoulder的宾语，指承担责任。
【小题8】fight – fighting前面的介词for后面要接动名词doing的形式。
【小题9】friend – friendly本句指的形容词friendly和系动词are在一起构成系表结构。
【小题10】rethink – rethought本句是虚拟语气It is time后面的从句可以使用过去时或者should+动词原形的形式。本句中使用了过去时的时态。
