考题讲解

题目分析:


选项分析:

A选项:Correct. 本选项在语法和逻辑上均是正确的。

B选项:复数名词 20-foot-long implements和单数名词a bull rake在单复数上不匹配,由于两者上known as的关系,所以应单复数一致。

C选项:working year-round和using such all-weather instruments as a hydraulic dredge or a 20-foot-long implement均为分词短语,这使得本选项没有谓语动词。

D选项:本选项错误同选项(B)。

E选项:for example措辞有误。 这两个短语都可以作"例如"解。for example用来举例说明某一论点或情况,一般只举同类人或物中的“一个”为例,作插入语,可位于句首、句中或句末。例如:   
Ball games, for example, have spread around the world.(例如,球类运动已经在世界各地传播开了。)    
What would you do if you met a wild animal - a lion, for example? (如果遇上野兽,例如狮子,你该怎么办?  ) 
such as用来列举事物时,一般列举同类人或事物中的几个例子。插在被列举的事物与前面的名词之间,as后面不可有逗号。例如:   
Some of the rubbish, such as food, paper and iron, rots away over a long period of time. (有些废物,如剩饭、废纸和废铁,时间一久就烂掉了。)
在本题中,由于例子有两个,所以应该用such as,而不能用for example。
