语法

点拨
(1)定义
在复合句中,修饰某一名词或代词的从句叫定语从句。被
定语从句修饰的词叫先行词;引导定语从句的词叫关系词。如:
I love singers who write their own
的歌手。
I like music that I can dance 。
(2)用法
若先行词是人,且在从句中做主语,关系词用 who 或 that;
做宾语时,可用 whom 或 that,且常可省略。若先行词为物,
且在从句中做主语或宾语,关系词用 which 或 that;做宾语时
可省略。whose 既可指人又可指物,在从句中做定语。
(3)只能用 that,不能用 who 或 which 引导定语从句的情况
①当先行词为 none, little, all, much, everything, anything 等
不定代词,或先行词被不定代词修饰时。如:
Is there anything else that you require?你还需要一些其他的
什么东西吗?
②当先行词被序数词或形容词最高级修饰时。如:
This is the best novel that I have ever
的小说。
③当先行词被 the same, the last, the only, the right, the very
等词修饰时。如:
This is the very film that we
电影。
④当先行词既有人又有物时。如:
The foreign visitors spoke highly of the pioneers and their
performances that they saw at the Children's
赞扬了他们在少年宫所看到的少先队员以及他们的表演。
注意:关系代词做从句的主语时,从句的谓语动词要跟先
行词保持数的一致。
②shall/will+动词原形:表示将要发生的动作或情况,没
有太多的计划性, 还用来表示意愿。如:
Shall we visit Granny Li next week ?下周我们去拜访李奶
奶好吗?
