专题06 从句
(定语从句、名词性从句、状语从句)
Part01 定语从句
1:考点梳理
1. 引导定语从句的关系词;
2. 限制性与非限制性定语从句的区别;
3. “介词+关系代词”的结构;
4. 关系词之间的异同及选用。
考点1 定语从句的种类
(1)限制性定语从句
从句在句中是不可缺少的部分,去掉后主句意思往往不明确,与主句之间不用逗号隔开。
This is the house which we bought last month.
(2)非限制性定语从句
从句是对主句或先行词的补充和说明,去掉后不影响主句的意思,与主句之间往往用逗号隔开。
The house, which we bought last month, is very nice.
当先行词是专有名词或被物主代词/指示代词所修饰时,其后的定语从句通常是非限制性的。
Charles Smith, who was my former teacher, retired last year.
My house, which I bought last year, has got a lovely garden.
非限制性定语从句还能将整个主句作为先行词,对其进行修饰,这时从句谓语动词要用第三人称单数。
He seems not to have grasped what I meant, which greatly upsets me.
