英语语法之定语从句
英语语法系列之形容词从句(定语从句),不得不说的先行词!
1.关系代词的用法(that、which、who……)
①Harry Porter is a boy.
②The boy has magic power.
合并前的准备
①Harry Porter is a boy.(主句不变)
②Who(the boy)has magic power.
(从句把与 主句重复的部分 换成关系词,the boy换成who)
(表人用who,表物用which,that既能表人也能表物,但that暗含有指示的功能!)
(重复的部分在主句中叫先行词!!!)
合并
Harry Porter is a boy who has magic power.
意义:我们用一个句子不能深层次的描述一件事物(或人物),所以我们用两个句子,两种角度合并起来 立体的描述它(他),但我们又要分清主次!
当然我们可以站在更多角度来解释一件事物(或人物),但冗长的句子让人崩溃,所以人们将句子的从句们全部简化(简化形式to do、doing、done),这就是我们常见的超长复合句!
① I like the book.
② You bought the book yesterday.
合并前的准备
① I like the book.(主句不变)
② You bought which yesterday↓.(the book换成which)
②which you bought yesterday.(关系词必须提前)
合并
I like the book which you bought yesterday.
2.关系副词的用法(when、where、why……)!
① This is the place.
② I was born in the place.
合并前的准备
① This is the place.
② I was born in which.↓(用which替换the place)
② I was born where.↓(in which = where)
② where I was born.(关系词提前!)
合并
This is the place where I was born.
这是形容词从句(表语从句),不是状语从句!他们有区别,但有时可以相互转化!下回说!
① Can you tell me the reason?
② You lied to me for a reason.
合并前的准备
① Can you tell me the reason?
② You lied to me for which↓.(用which替换a reason)
② You lied to me why↓.(for which=why)
② Why you lied to me.(关系词提前)
合并
Can you tell me the reason why you lied to me?
