英语各项句式怎么理解（定从、状从、宾从、同位从…）区别,有啥区别?
他们有什么区别?我学了新语法前面的就忘了,或者混了,咋区分?

Answer 1

英语中从句有三种：状语从句（副词性从句）；定语从句（形容词性从句）；名词性从句（包括主语从句,宾语从句,表语从句和同位语从句）.什么名称的从句即在整个句子中充当什么样的成分.例如：
状语从句：
1.i didn't catch the train because i get up late this morning.(because引导的原因状语从句)
2.if it should rain tomorrow ,we would put off the meeting.(if引导的条件状语从句)
3.As I was wandering in the street,I met her.（as引导的时间状语从句）
4.Where there is a will,there is a way.（where引导的地点状语从句）
5.Although (though) I gave him some advice,he didn’t take them.（although引导的让步状语从句）
6.You should do your homework as i did.（as引导的方式状语从句）
7.Cherry was walking quickly so that (in order that) she could arrived at the cinema in time.（so that 引导的目的状语从句）
8.She is such a nice teacher that all of us love her.（such..that引导的结果状语从句）.
定语从句
是相当于形容词的作用限定修饰名词或代词的.所以定语从句一般是放在名词或代词后面的.（定语从句分限制性定语从句和非限制性定语从句,今天实在没时间打那么多了,改天再细细告诉你两者区分吧）.
1.The man who helped you is Mr White.(who代人,在定语从句中作主语)
2.I´m not the fool(that) you thought me to be.(that代人,在定从中作表语)
3.The house where they live is not very large（where指in the house）
4.This is the reason why he did not came to the meeting.（why引导的从句限定reason）
但不是表时间的先行词都用when引导定从,不是表地点的先行词都用where引导定从.
例如：5.We´ll visit the factory which(＝that) makes radios.
(which或that在定从中作主语,where不可用主语,故不可用)
6.They still remember the happy days(which/that) they spent in Beidaihe.
(which或that在定从中作spent的宾语,when不可作宾语,故不可用)
名词性从句
主语从句用作主语,如：：
That the earth is round is true.地球为圆的是真实的.
宾语从句用作宾语.如：
Do you know where he lives?
表语从句用作表语,如：
My opinion is that you should not go alone.我的意见是你不应单独前往.
同位语从句用于解释说明前面的名词.如：
The fact that the earth is round is true.地球是圆的的事实是真实的.（that从句用于解释说明the fact）
