考题讲解

题目分析:
本题考点很多,可以用各种方法杀掉错误选项。

选项分析:

A选项:介词短语in its spending its entire life cycle在本选项中做a species of midge is unlike any other knowninsect的状语。这在语意上是不正确的。例如:
James is unlike Jack in his GMAT score.
该例句的意思是:詹姆斯在他的GMAT成绩方面和杰克是不同的。这句话暗示,詹姆斯可能在很多其它地方和杰克比较相似,只在GMAT成绩方面有些区别。同理于本选项,本选项的意思是:
这种蚊子在整个生命都在冰层中这个方面和其它已知昆虫是不同的(a species of midge is unlike any other knowninsect in its spending its entire life cycle in the snow and ice of a glacier)。
其暗示:蚊子和其它昆虫在别的方面比较相似。在本选项中,我们无从得知蚊子和其它昆虫是否在其它方面是相似的,因此不能用这种表达方式。只能说:
unlike any other known insect, a species of midge spends its entire life cyclein the snow and ice of a glacier.
该例句只说明了蚊子和其它昆虫在整个生命都在冰层中这个方面不同,没有暗示其它方面的情况。

B选项:insect前面的other不能少,因为,a species of midge本身就是一个生物,它只能和“其它”的生物都不像,不能自己和自己不像(unlike)。

C选项:Correct. 本选项在语法和逻辑上均是正确的。

D选项:because是连词,只能连接两个句子。本选项中其连接的两个句子是a Japanese zoologist has found a species of midge unlike any insect known和it spends its entire life cycle in the snow and ice of a glacier(状语就近修饰一个句子),但在逻辑上这两句话显然没有因果关系;insect身前缺少other错误同(B)。

E选项:spending是现在分词,因此短语spending its entire life cycle做伴随状语,其主语为any other insect(其最近的句子是定语从句that is known,所以它的主语和这个从句的主语相同),但是spend在逻辑上的主语应该是a species of midge,而不是any other insect。
