如何選擇定語從句的引導詞

限制性定語從句修飾先行詞，對先行詞起修飾作用，不同引導詞有不同的含義和用法，下面，小編就來給大家分享一下選擇定語從句的引導詞的技巧，一起來看看吧！

*限制性定語從句

 限制性定語從句修飾先行詞，對先行詞起修飾作用，緊接先行詞之後，無逗號，若省去，原句意思不完整。引導定語從句的關係代詞有who, whom, whose, which, that等。who, whom, whose用於指人，whose有時也可指物，相當於of which；which用於指物；that既可指人也可指物，但只用於限制性定語從句中。關係代詞除了引導定語從句，替代先行詞外，還在從句中擔任主語、賓語、定語等。

*非限制性定語從句

非限制性定語從句既可修飾先行詞，也可修飾整個主句，起補充說明作用，與主句之間有逗號隔開，若省去，原句意思不受影響。不可用that引導非限制性定語從句。關係詞不可省略。

定語從句的引導詞有關係代詞who， whom，whose，which，that， as；關係副詞when， where，why。定語從句中引導詞的選用主要看先行詞在定語從句中作什麼成分或者是定語從句中缺什麼成分。

1．定語從句中缺主語，修飾人時用who ／that，修飾物時用which ／that引導。如：

Is this the factory which ／that makes TV sets？

The man who ／that visited our school is from Australia．

2．從句中缺賓語，修飾人時用 who ／whom ／that或省略引導詞；修飾物時用which ／that或省略引導詞。如：

Gone are the days which ／that we spent together in the village．

He is the man who ／whom ／that I think to be worthy of our praise．

3．從句中缺時間狀語，用when或介詞＋which引導。如：

The day finally came when ／on which I was given a job．

We'll put off the outing until next week，when we won't be so busy．

4．從句中缺地點狀語，用where或介詞＋which引導。如：

Please put the letter on the desk where ／on which he can easily find it．

5．從句中缺原因狀語或先行詞是 reason時，引導詞用why ／for which ／ that。如：

This is the reason why ／for which ／ that he didn't come to the meeting．

6．從句中缺定語，人和物都用 whose引導。如：

A child whose parents are dead is called an orphan．

Please pass me the dictionary whose cover is black．

7．當先行詞是way時，其定語從句的引導詞用in which ／that。如：

The way in which ／that he looks at problems is wrong．
