主从复合句要点精编+练习(总复习)

主从复合句要点精编（总复习）
三类从句：名词性从句、定语从句、状语从句
从句考两点：连词 (是否有意思，在句中充当什么成分，是否可省)、语序（陈述语序）。

陈述语序：The photographs will show you what our village looks like.
（除了what’s the matter 不变）
名词性从句
1. “主语”的位置是句子，那个从句就是“主语”从句。

（宾语、表语、同位语）
2. 名词性从句连词有：(下划线的连词定语从句中不可用)
（1）that;（通常不可省，只有在宾语从句中可省。

）
（2） wh- (what, who, whom, whose, which, where, when, why, whether, how);
（3）whatever, whoever, whichever, wherever, whenever, however.
3. what和that区别
What he said makes me happy.
That a new teacher will come is true. = It is true that a new teacher will come.
4. 主语从句谓语一般情况下用单数。

Whether they will come depends on the weather.
5. whether和if区别
主语从句、表语从句、同位语从句、介词后的宾语从句、直接加动词不定式whether （to do）、whether or not连用时都不能使用用if。

If只在动词后的宾语从句中可以与whether互换。

Eg. I don’t know if / whether I’ll be fre e tomorrow.
6. whatever和no matter what区别
这两者在让步状语从句中可互换，名词性从句中只能用whatever
No matter who destroys the forest will be punished. ×
Whoever destroys the forest will be punished . √
7. it做形式主语和形式宾语
(1) 形主That he made such a mistake is a pity. = It is a pity that he …
形式主四大句型：
It be + adj + that…eg. It is obvious that he misunderstood me.
It be + n + that…eg. It is a pity that he failed to get full marks.
It be + p.p. + that…eg. It is reported that a flight crashed in Pennsylvania.
It + seems
happens +that eg. It appears that the picture has been hung upside down.
appears
(2) 形宾make /find/ feel / consider / think it + adj / n + that…
= think it + adj / n + to do sth
状语从句
特殊连词：[as, since]多种状语从句中可用，意思不同; [once, in case]归属不绝对.
定语从句
1. 定语从句的连词有：(that, who, whom, whose, which); (where, when, why); (as).
2. 限制性定语从句和非限制性定语从句（非限制中that和why不可使用）
