2019人教新版高中英语必修二 Unit5 Music 语法

Unit5 Music-语法篇____________________________________________________________________________________________________________________________________________________________________通过本节课的学习掌握由“介词+which/whom”引导的定语从句的用法。

定语从句（由“介词+which/whom”引导的定语从句）一．关系代词的选择当关系代词在定语从句中充当介词的宾语时，我们可以用“介词+关系代词”引导的定语从句。

如果先行词为人时，用“介词+whom”；如果先行词为物时，用“介词+which”。

Who与that不能用此结构，但介词后置时可以使用，如果作宾语也可以省略。

The ladder on which I was standing began to slip.我脚下的梯子开始向下滑动。

The reason for which he didn’t come to school was that his mother was ill.他没来上学的原因是他的妈妈病了。

二．介词的选择介词的选择主要从以下几方面考虑：1. 从先行词跟介词的搭配出发I’ll never forget the day on which we worked together in the countryside.我不会忘记我们一起在乡下工作的日子。

(把the day代入从句后，加on 才构成完整的句子，即we worked together on the day in the countryside)The clever boy made a hole in the wall, through wh ich we could see what was happening inside the house. 这个聪明的孩子在墙上挖了一个洞，透过它我们可以看到屋里发生的事情。
