Step 6 Special cases
A. 关系词只能用that而不用which的情况

1．当先行词为all,everything, nothing, anything, much等不定代词时。

Have you takendown everything that Mr Li said?

All that can be done has been done.

2．先行词被序数词或形容词最高级修饰时。

The first placethat they visited in London was the Big Ben.

This is themost delicious food that I have ever had.

3．先行词被all,every, no, the only, the very, the last等修饰时。

Ive read allthe books that are not mine.

The only thing that she could do was to go to the police for help.

I have foundthe very pen that I lost yesterday.

4．当先行词既指人，又指物时。

He made aspeech on the men and things that he had seen abroad.

B.“介词＋关系代词”引导的定语从句

当关系代词在定语从句中作介词的宾语时，我们通常用“介词＋关系代词”引导定语从句。如果指“人”，用“介词＋whom”；如果指“物”，用“介词＋which”；关系代词有时也用whose(作定语)。

选用介词的依据：

1．根据定语从句中谓语动词的搭配习惯(即固定短语)。

Yesterday wevisited the West Lake for which Hangzhou is famous.(be famous for“因……而出名”)

2．根据先行词的搭配习惯(约定俗成，不一定是短语)。

This is thecamera with which he often takes photos.(with camera“用照相机”)

The boss inwhose company Mr King worked heard about the accident.(in the boss company)

3．根据句子的意思来选择。

The colorlessgas without which we cannot live is called oxygen.

4．表示“所有”关系或“整体中的一部分”时，通常用介词of。

I have about 10books, half of which were written by Mo Yan.

注意：在定语从句中，有一些含介词的动词短语不可拆开使用，如look after, look for等不能把介词移至which或whom之前。
