Antarctica receives more solar radiation than does any other place on Earth, yet the temperatures are so cold and the ice cap is reflective, so that little polar ice melts during the summer; otherwise, the water levels of the oceans would rise 250 feet and engulf most of the world's great cities.
is reflective, so that little polar ice melts during the summer; otherwise,
is so reflective that little of the polar ice melts during the summer; were it to do so,
so reflective that little polar ice melts during the summer, or else
reflective, so that little of the polar ice melts during the summer, or
reflects so that little of the polar ice melts during the summer; if it did
题目分析:
本题主要需要记忆关于虚拟语气的相关用法及概念。正确选项中的were it to do so是一个虚拟语气下的条件状语,正常语序为:
if it were to do so
选项分析:
A选项:首先,应该是so cold和so reflective对应。其次,otherwise应改为were it to do so.
本选项的otherwise是“否则”的意思,一般我们会说:
I was ill that day, otherwise I could have taken part in the sports meet.
例句中,otherwise相当于if I were not ill.(虚拟)
同理,这本选项中,如果用otherwise,则可以相当于if little polar ice did not melt.(相当于在谓语动词那里加否定词)。
这时你会发现,逻辑上不对。
不是说,如果很少的冰不熔化,那么水位就会上涨。
而应该是,如果冰都融化了,那么水位就会上涨。
因此,otherwise是不正确的。
B选项:Correct. 本选项在语法和逻辑上均是正确的。
C选项:本选项缺少谓语动词,ice cap和so reflective之间应当添加谓语动词;另外,or else应该用虚拟语气替代。
D选项:本选项错误同(C)。
E选项:冰盖(ice cap)应该是具有反射性(reflective)而不是主动发出反射这个动作,因此应将reflects改为is reflective。另外,if it did是真实条件句,应改为虚拟语气。
太傻了,竟然用little of和little来排除
这里最重要的splits应该是后面的转折(or不能说转折,是假设)
句意是最重要的
