考点二、介词与关系代词连用

作介词与关系代词连用的习题时，要看两点：一看先行词前需要什么介词，二看定语从句的谓语动词后需要什么介词。最简单的方式就是将定语从句还原成一个独立的句子，结果就一目了然。如：

1、The place at which the bridge is supposed to be built should be where the cross-river traffic is the heaviest. (定语从句还原就是：The bridge is supposed to be built at the place. 这样就可以判断引导词需要介词at。也可以看先行词the place前需要介词at进行判断。)

2、I saw a woman running toward me in the dark. Before I could recognize who she was, she had run back in the direction from which she had come.(从句还原就是：She had come from the direction，所以定语从句用from which 引导。)

3、There was a single person in the street to whom she turned for help.(从定语从句的谓语动词turn可构成词组turn to sb. for help就可以判断应该填to whom。)

4、The man about whom I talked just now is from Beijing University.(根据定语从句的谓语动词talk判断后需要of或about，因此此处需要about/of whom)

考点三、从句中的主谓一致

当定语从句的引导词在从句中作主语时，定语从句的谓语动词必须与先行词保持一致，这时引导词与谓语动词的数无关。如：

1. Tom is the only one of the workers in our company who has won a nation-wide fame.(汤姆是我们公司唯一一个赢得国家荣誉的工人。先行词为the only one。)

2. Tom is one of the workers in our company who have won nation-wide fames.(汤姆是我们公司赢得国家荣誉的工人之一。先行词为the workers。)

3. I, who am your friend for ever, will never turn against you. (我，你永远的朋友，永远也不会背叛你。先行词为I。)

考点四、几种特殊的定语从句

1. the way 和the time的定语从句的引导词一般用that引导，可以省略。如：

(1).I think the way (that) he told me is the best.我认为他告诉我的方法是最好的。

(2).Today is the time that we began to work on plane model.今天是我们动手做飞机模型的时候了。

2. 定语从句中含有插入语时，做题时可将插入语直接去掉 ，题目就简单明了。如：

We feed the children who we think are hungry.我们喂了那些我们认为饥饿的孩子。

This is the man who I believe is very honest.这就是那个我认为很诚实的人。

说明： 常用于插入语的动词有：believe, think, suppose, guess, say 等等。

考点五、分隔式定语从句

定语从句有时不直接跟在先行词的后面，中间由一个定语、状语、谓语隔开。如：

(1).The days are gone when the Chinese people were looked down upon.

(2). Do you remember one afternoon ten years ago when I came to your house and borrowed a diamond necklace from you?(你记得我来到贵府借一个钻石项链10年前的一天下午吗?)

(3). There is an expression in his eyes that I can’t understand.我不能理解他眼中所表达的东西。

命题特点：

1、 定语从句引导词与代词的用法混淆考查。

2、 定语从句引导词与状语从句的连接词混淆考查，特别是where和when。

3、 as和which引导非限制性定语从句的考查。

4、 连接词that/which/what的辨析。

5、 引导词whose/where/that和介词+关系代词的考查。

6、 where引导的定语从句、状语从句和名词性从句的辨析。

7、 定语从句和强调句型的辨析。
