The Orange bear with a Primrose 小櫻棕熊

which 指人以外之生命，無生命者都可以用which

例句:

1. He likes the house which has many windows.

2. Where is the letter which I received yesterday?

3. I like the house which he lives in.

that 用法

1. 先行詞是人或動物
2. Who,which 開頭疑問句，為避免重複，用that

-Who is the man that has white hair?

-Which is the book that you borrowed from the library?

1. It is…that 的強調用法

It is Columbus that discovered America in 1492.

1. that前不可有介詞或逗點 (所以有介詞或逗點時要選who,which)

I will lend you the book, which is interesting.

I have two brothers, who live in Taipei.

想一想上面的規則，考考你:

-This is the house (in that/ in which) he lives. 選哪一個?

-I will lend you this book (, which/, that) is useful. 選哪一個?

正解:

   - in which   that前不可有介詞

-, which   that前不可有介詞或逗點

1. that的瑣事: (這裡解釋了為什麼有時候必選that不可。)

-先行詞中有序數

Henry Ford was the first man that built cars.

-先行詞中有最高級

This is the most interesting book that I have ever read.

-先行詞中有the 家族 (the only 唯一；the very正式那個；the same同一個)

Man is the only animal that can speak.

This is the very book that I like very much.

-先行詞中有任何/全部/無一 (任何any/全部all/無一no)

Anyone that listens to him is a fool.

 what 用法

what = 先行詞+關係代名詞

what = the thing which

     = that which

     = all that

請把以下” 先行詞+關係代名詞” 改成what

因為使用what句子變簡短有力了。

 This is the thing which I need. = ? This is what I need.

Do you understand all that I said? = ? Do you understand what I said?

He saves all that he earned. = ? He saves what he earned.

The thing which he said is true. = ? What he said is true.

注意:

1. 因為what本身已經有先行詞和關係代名詞的意義了，所以如果出現what，前面就不應該再出現先行詞，例如: that, the thing,…
2. what 本身就可以當作主詞、受詞或補語，(和which, that不同，which, that 只能當關係代名詞使用)
