定语从句专题讲解

　　11、关系副词when与where、why、that

　　when 指时间 = in / at / on / during which

　　where指地点 = in / at / from / which

　　why指原因 = for which

　　当先行词为way、day、reason、time时，可用that作关系副词。（非正式场合）

　　I don’t like the way that / in which / he talks.

　　当time作先行词时，关系词可以省掉。

　　This is the first time I have given you a lesson in French.

　　12、必须注意的问题

　　（1）关系词作主语时，从句中谓语的数。

　　（2）注意区别定语从句与强调句。

　　①定语从句中关系词作从句成分，复合句。

　　②强调it无意义，that / who不是引导词。

　　③强调it is / was和that / who后如果句子意思讲得通则是强调句，讲不通则不是。

　　It is the museum that/which we visited last year.(定语从句)

　　It was in the hotel that we stayed last night.（强调句）

　　（3）定语从句与同位语从句的区别。

　　①定语从句引导词被称为关系词，that充当主语、宾语、表语。有时可省略。

　　②同位语从句引导词被叫做连词，that不能充当任何成分，不可省。

　　Word came that their army was defeated.(同位语)

　　We expressed to them our wish that was the same as their.(定语)

　　（4）关系词在从句中省略的情况。

　　①关系词作宾语，前无介词时。

　　②关系词作表语。
