Grammar--定语从句导学案 2018.11

1.定语从句在从句中起定语作用，修饰句中的某一名词或代词，被定语从句修饰的词叫先行词。定语从句一般紧跟在先行词后面.(定语从句有时候还可以修饰一个句子,通常指代一件事情)

2.引导从句的关联词叫关系词,关系词分为关系代词和关系副词

关系代词：who, whom, whose, that, which, as等（在句中作主、表、宾、定等成分）

2.只能用whom不能用who的情况:

① 先行词在从句中作介词的宾语且介词前置,如

Tom is the boy with whom I have talked with.==Tom is the boy who/whom I have talked with.

3.关系代词必须用that的情形：

①当先行词被形容词的最高级所修饰

②当先行词被序数词修饰

③当先行词被the only, the very等修饰

④先行词被all, every, no, some, any, little(少量,一些), much等修饰时：

⑤当先行词为all, much, little(少量,一些), few, none, something, anything, everything, nothing等不定代词时，

⑥当先行词既指人又指物时

He talked about the teachers and schools that he had visited.

⑦当关系代词在从句中作表语时：

Mary is no longer the girl (that) she used to be.
