使用定语从句的几个误区（四）

使用定语从句的几个误区（四）　　

1.误认为关系代词whose只用于修饰人　　

whose用作疑问代词时，主要用于指人；但用作关系代词时，它既可指人也可指物。如：　　

It was an island, whose name I have forgotten. 它是一座岛，名字我忘了。　　

The factory, whose workers are all women, is closed during the holidays. 这家工厂工人都是妇女，在假期中工厂关门了。　　

2.混淆定语从句与并列句　　

请看下面两题：　　

(1) He has two children, and both of _______ are abroad.　　

A. them                  B. which                    C. whom                    D. who　　

(2) He has two children, both of _______ are abroad.　　

A. them                  B. which                    C. whom                    D. who　　

第(1)题选A，第(2)题选C。由于第(1)题中用了并列连词and，从而使整个句子为并列句，and后应是一个独立的简单句，所以选A不选C；第(2)题没有并列连词and，both of whom are abroad为非限制性定语从句。另外，请比较下题(答案为A)：　　

He has two children, both of _______ being abroad.　　

A. them                  B. which                    C. whom                    D. who　　

3.误认为逗号后一定是非限制性定语从句　　

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。如：　　

(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. 　　

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

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。
