备考定语从句的七个错点

2020-10-22来源:和谐英语

 

五、混淆关系代词与关系副词

有的同学一看到先行词是表示时间、地点、原因的名词,就认为一定要用关系副词,其实也一定。在此情况下,还要看关系词在定语从句中是用作什么成分,若是用作状语,则用关系副词,若不是用作状语(如用作主语、宾语等)则不能用关系副词,而用关系代词。比较:

This is the factory where I want to work. 这就是我想工作的工厂。(work为不及物动词where在从句中用作状语)

This is the factory that I want to visit. 这就是我想参观的工厂。(visit为及物动词,that用作visit的宾语)

The reason why he can’t come is that he is ill. 他没来的是因为他病了。(come为不及物动词,why在定语从句中用作状语)

The reason that he put forth is very important. 他提出的理由很重要。(put forth为及物动词,that在定语从句中用作其宾语)

 

六、因逗号误判which

有的同学一看见逗号,就以为一定要选which而不选that,但问题是有时根本就不是定语从句:

(1) If a book is in English, _____ means slow progress for you.

A. as        B. which      C. what        D. that

(2) When I say two hours, _____ includes time for eating. (D19/541)

A. as        B. which      C. what        D. that

【分析】以上两题均应选that,而不能选which,因为它们根本不是定语从句。之所以选that,是因为句中已有if和when引导的状语从句,逗号后为主句,that为主句主语。

 

七、混淆whichwhose

两者在定语从句中都可用作定语,区别是:whose 的意思相当于 one’s,而 which 的意思则相当于 that 或 this。比较:

(1) This is Mary, whose [= and her] father we met last week.

(2) Call again at 11, by which time [= and by that time] the meeting should be over.
