题目分析:
略。
选项分析:
A选项:本选项具有语法错误。未划线部分的whereas the honeybee’s stinger is heavily barbed and cannot be retracted from the skin是由连词whereas引导的状语从句,划线部分中because the yellow jacket has a comparatively smooth stinger是原因状语从句。在语法上,当一个主句拥有两个状语从句时,应该用并列连词and连接,不能直接扔在主句身前,例如:
(1) Because I was hungry and because I wanted to have a rest, I stepped into that restaurant.
(2) ** Because I was hungry, because I wanted to have a rest, I stepped into that restaurant.
句(2)是错误的。
B选项:代词them是复数代词,只能指代复数名词,但是本题中的yellow jacket是单数名词。另外,并列连词and连接的两句在语法上虽然没有问题,但是补出and身后省略的主语则有:
the comparative smoothness of the yellow jacket’s stinger used again.
显然地,use的发出者不能是smoothness。
C选项:Correct. 本选项在语法和逻辑上均是正确的。
D选项:介词短语in comparison和whereas均表示对比,因此in comparison赘余。
E选项:in comparison赘余错误同选项(D)。
in comparison和whereas均表示对比,因此in comparison赘余。
