定語從句，我們從初中開始接觸，並且在高中徹底相識。定語從句到底有多重要呢？

歷年高考的英語考試，短文填空（15分）短文改錯（10分）至少有一空都和定語從句有關。我們往往會糾結到底是填that還是填which，又或是填who還是whose。既然年年有，那麼知悅這裡一定是有乾貨噠。

對定語從句還不瞭解的同學請看這裡。

首先，我們先來看看框架圖：

這是我們高中需要掌握的主要內容，事實上高考考的內容並不多，其主要考點是引導詞的用法。

注意啦！注意啦!乾貨要來啦!

一、只能用that作為引導詞。

1.先行詞為數量代詞。

注意詞組：none,any,(a) few/little,some,most,all,much,many,half,so percent,one of等

例：She did all that she could to help me.

例：There is no difficult that we can't smooth away.

3.先行詞有不定代詞

注意詞組：nothing,anything,someting,everything

例：Is there anything that you want to ask me?

4.先行詞被最高級和序數詞修飾

注意詞組：the last....,the next....

例：This is the first time that I have been aboard.

You are the last person that I want to see.

5.先行詞為基數詞

例:4 and 4 makes 8 that is a lucky number in China.

6.先行詞被語氣助詞修飾

例：He dose badly in study,which makes his parents upset.

3.先行詞為that

4.先行詞被介詞短語，插入語，同位語等分開

三、定語從句的特殊用法及對比

1.from where,since then

例：He stood at the north window,from where he could see the whole garden.

2.who,which在疑問句裡用that

例：Which is the novel that you like best?

Who is the person that is seated there?

例：There are some cases where the rules can't be followed.

I'll show you the point where you fail.

We have come to the position where we must make the best efforts to overcome the great difficulty.

4.as引導的定語從句

Taiwan,as we all know,belongs to China.——插入語

Taiwan belongs to China,as we all know.——定語從句（as可換為which)
