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?
