使用定语从句的几个误区|定语从句

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 apoad.

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

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

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

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 apoad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 apoad.

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 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 ，初学者在使用定语从句时，有个经常犯的错误就是分不清是定语从句还是其他从句。请看下面的题目： —Is this room __________ he lived in last year?

—Is this the room __________ he lived in last year?

A. that, that B. the one, the one C. that, the

one D. the one, that

此题应选D 。容易误选A 。为了便于分析，我们先将以上两句还原成陈述句(注意is 的位置) 。如：

(2)This is the room ________he lived in last year.

第(1)句填the one, 用作表语，其后的 (that) he lived in last year是用以修饰the one 的定语从句。此句若直接填that, 则不是定语从句(因为没有先行词) ，而是表语从句。

但是由于引导表语从句的that 不能充当句了成分，而其后的介词in 又缺宾语，所以导致错误。

请做以下类例试题。如：

(1)—Is this the book _________ you want to buy? —Is this book _________ you want to buy?

A. that, that B. the one, the one C. that, the one D. the one, that

(2)—Is this room ___________ he lived in 5 years ago? —Is this the room __________ he lived in 5 years ago?

A. that, that B. the one, the one C. that, the one D. the one, that 答案：(1) C (2) D 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，其实也不一定。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)
