摘要：大家都知道定語從句是寫作中經常會用到的句子，但是關于定語從句that的用法卻有些混亂，以下幾種情況，是在雅思寫作中定語從句要注意的。

大家都知道定語從句是寫作中經常會用到的句子，但是關于定語從句that的用法卻有些混亂，因為that可以接同位語從句比如：The news that a whole family was murdered in Ningxia shocked the public. 而且在定語從句中，如果先行詞在從句中作賓語成分，又可以用that代替which和who，那么有沒有哪些情況是只能用that而不是用who和which的呢?當然有，以下幾種情況，是在寫作中定語從句要注意的。

第一種情況：

當先行詞即有人又有物的時候，那么這個引導詞就是that，比如說：I know about GuoJingming and his books that are very popular with young people in China.

The Nobel Prize winners and their achievements that my teacher told me when I was a little girl influenced me a lot.

第二種情況：當先行詞是anything, everything, nothing ,few, all, none, little, some等代詞時，后面的關系詞就是that，that 也可以省略如

I have nothing that I think I should tell you.

That is all that I know.

第三種情況，當先行詞是表示特指的時候，如only very right 來修飾乳

He is the only guy that I saw tomorrow in the classroom.

That bag lied on the floor was hers.

That factory that I visited yesterday is a deserted one.

第四種情況，當先行詞被序數詞，或者形容詞的最高級修飾的時候;

The first novel I read is written by Dickens.

The only thing that we can do now is to pray.

第五種情況： 句中其他位置已出現which， 為避免重復， 不用which而用that引導限定性定語從句。

Which is the car that has overtaken us?

Which table is the one that we repaired yesterday?

希望通過這幾種情況的講解，能讓大家對定語從句that的用法有更深刻的認識！
