(3)關係代名詞的省略

受格可省略，非限定用法(逗點後)不可省略，若此受格本為介詞之受詞，則介詞可前調至關代前，介詞之後受格亦不可省略，介詞之後亦不可用that。

The books which I bought yesterday are very good. (正)

The books that I bought yesterday are very good. (正)

The books I bought yesterday are very good. (正)

This is the book which I am looking for.(正)

This is the book that I am looking for. (正)

This is the book I am looking for. (正)

This is the book for which I am looking. (正)

This is the book for that I am looking. (誤…介詞之後不可用that)

This is the book for I am looking. (誤…介詞之後受格不可省略)

I bought two good books, which I found in the fair. (正)

I bought two good books, I found in the fair.(誤…逗點後受格不可省)

I bought two good books, that I found in the fair. (誤…逗點後不可用that)

主格原則上不可省略，從屬子句若有be動詞，則主格連帶be動詞可一起省略而形成分詞片語、介詞片語、不定詞片語，依然做為形容詞使用，其原理與分詞構句，副詞片語相同。

       He is the man (who is) called John.-----------------------他就是叫作John的人
       He is the man called John.

        I know the boy (who is) running there.-----------我認得正在那兒跑步的男孩
        I know the boy running there.

The girl (who is) in the room is Mary.--------------------房裡的那女孩是Mary

The girl in the room is Mary.

The cell phone (which is) with a ring is Mary’s.-有吊飾的那手機是Mary的

The cell phone with a ring is Mary’s.

I am the one (who should be) to blame(to be blamed).-------該受責者乃朕也

        I should be the one to blame. (to be blamed)

主格原則上不可省略，但遇到主要子句以There is, It is, Here is 開頭，則關係代名詞雖為主格，口語上常省略。(非正式用法)

There is a man (who) wants to see you outside.-------------外面有個人想見你

= There is (that) a man wants to see you outside.

= There is a man wants to see you outside.
