2.不能透彻地理解“关系代词”具有的三种功能

1)、在从句开头引导一个定语从句；

2)、指代或替代先行词且先行词不可省，引导词有时可省；

3)、在定语从句中作适当成分。

例2、Put the book ___ it should be when you have finished reading it.

　　　 A. where　　 B. in which　　 C. at the which　　 D. the place where

[点拨]此题答案是A. where，但where并非引导定语从句，而是一个地点状语从句。学生极易选B或C。选项B错在in which 若引导定语从句，其前的先行词不可省，而the book不能做表地点的先行词；选项C若看成一个定语从句，倒是有个先行词the place ，但定语从句引导词在从句中要做标语，此时引导词不能省略；但从句中做宾语时引导词则可省。

经典真题回放：

1、不能区别定语从句与别的从句或结构。

例1. It was about 600 years ago ___the first clock with a face and an hour hand was made.

A. that　　 B. until　　 C. before　　 D. when

[点拨] 此题学生极易选D. when，而答案为A. that，选D恰恰是把定语从句与强调句型结构弄混了。这两种结构十分相似，稍不注意便会出错，而且这类题目刚好是最近几年高考考查的热点。判断是否是强调结构的正确方法是删除法，即将“it is (was)---that --- ”部分去掉，若整个句子结构和意义不受其影响的话，则只能看作强调结构。此题去掉此部分后结构完整正确，故应看作是强调结构。

7. No/ never/ not+先行词+but(关系代词)=that…not= who…not没有…不…的

　 There was no man but admired him (=no man who didn’t admire him.)

　 There is no difficulty but may be smoothed away (=no difficulty that may not be smoothed away.)

6. 关系代词than引导的定语从句

You spend more money than was intended to be spent(超过预定数额).

5. 介词from+ where引导的定语从句(此句中的where可与which换用，但用法已陈旧)

We went up to the roof, from where we had a good view of the procession.

4. 多重定语从句(即两个以上的定语从句同时修饰一个先行词)

He said he would never forget the moment when he first met

Tom and which he regarded as the happiest in his life.

3. 省略式定语从句(即介词+关系代词+不定式；可以与介词+关系代词+定语从句结构转换)

She has a lot of thing with which to deal (=with which she should deal)
