复合句--主语从句
Lesson 71：
授课人：曾老师
复合句的概念：
一个简单句充当另一个简单句中的某一成份，则构成主从复合句：
I think (that) it is his cup.
Can you tell me whose bag this is
That’s what I want.
While we were talking, the teacher came in.
复合句中，从句套从句的情况也经常出现。比如：
Last year the Foundation reported that nearly 60% of 7 to 12-year-olds said they felt tired during the time
when they were having classes.
宾语从句
宾语从句中的宾语从句
▲ 符合一句一述原理。
但某段内容由一个
句子来充当。
从句标签词
It wasn’t until then that I finally found that the wounds would finally heal when I hurt someone physically, but when I hurt someone with my words, sometimes the pain never goes away.
定语从句
主语从句的类型及构成方式：
① 陈述句转过来的主语从句。比如：
That prices will go up is certain.
That she is still alive encourages us.
That she used to be a spy is known to all.
That he will come to our village tomorrow surprises us all.
That you are coming to London is the best news I have heard this long time.
▲ 需要注意的问题：
1. 从句位于句首时，标签词“that”不能省略。
2. 主语从句为单数形式，且从句中的时态不需要跟主句一致。
主语从句的类型及构成方式：
为避免头重脚轻，常以“it”来做形式主语，将真正的主语从句后置。比如：
It is important (that) we all should attend the meeting.
It’s certain (that) prices will go up.
It encourages us (that) she is still alive.
It surprises us all (that) he will come to our village tomorrow.
It was a pity (that) you didn’t go to the talk.
It is true (that) water freezes at thirty-two degrees Fahrenheit.
It is very likely that they will hold a meeting.
It is quite strange that he should do that. （虚拟语气，表竟然）
▲ 注意：用“it”来充当形式主语, 从句后置时标签词“that”可以省略。
主语从句的类型及构成方式：
这种句式的常见应用：
It is a fact that ...
It's an honor that ...
It's a good idea that ...
It's natural that ...
It's strange that ...
It is necessary that ...
It's important that ...
It happened that...
It doesn't matter that …
It is said that...
It’s told that…
It's reported that ...
It is suggested that...
It has been proved that ...
It is announced that...
It is known to all that...
It’s well-known that…
…
与类似结构强调句的区别：
强调句的结构是： It + be + 被强调部分 + that + 余下部分
The times produce their heroes. 时势造英雄
强调主语：It is the times that produce their heroes. ( produce的主语是the times，所以没有用三单 )
强调宾语：It is the heroes that the times produce.
▲ 请参阅：L77-感叹强调句式
再比如：
强调宾语：It is English that Prof. Lin teaches us.
强调状语：It was in shanghai that I saw the film.
主语从句的类型及构成方式：
② 一般疑问句转过来的主语从句。比如：
Whether she is still alive or not is still unknown.
Whether he will go there has been decided.
Whether he has gone there has not been told yet.
Whether they would support us was a problem.
▲ 需要注意的问题：
1. 这种情况下，只能使用标签词“whether”，不可以使用标签词“if”，因为使用“if”会产生歧义。
2. “whether”可以和“or not”搭配使用。
主语从句的类型及构成方式：
同样可以用“it”来做形式主语，将真正的主语从句后置。比如：
It is still unknown whether she is still alive or not.
It has been decided whether/if he will go there.
It has not been told yet whether/if he has gone there.
It was also a problem whether/if they would support us.
▲ 需要注意的问题：
这种情况下，既可以使用标签词“whether”，也可以使用标签词“if” 。
▲ 这种情况下再进行感叹强调：
What a pity it is that he can’t continue his dream now.
主语从句的类型及构成方式：
③ 特殊疑问句转过来的主语从句。比如：
Who will win is not my care.
Whom (who) he hates is my uncle.
What he did is very important for us.
Which team he liked is still unknown.
Whose key this is is very clear now.
What subjects he will like depends on the teachers.
▲ 需要注意的问题：
1. 主语从句为单数形式，且从句中的时态不需要跟主句一致。
2. 从句的语序永远是陈述句。
Whoever you meet can make you better.
Whatever you did is always right.
Why Tony did this remained a mystery.
How this happened is not clear to anyone.
Where he went for his weekend is not known.
主语从句的类型及构成方式：
常见的一些谚语：
What’s done is done.
What’s gone is gone.
What’s over is over.
What is lost is always lost.
Whatever you say goes.
Whatever will be will be.
结束的就结束了
过去的就过去了
结束的已经结束了
失去的就失去了吧
你说了算
顺其自然吧
主语从句的类型及构成方式：
同样可以用“it”来做形式主语，将真正的主语从句后置。比如：
It is not my care who will win.
It is my uncle whom he hates.
It is still unknown which team he liked.
It is very clear now whose key this is.
It can make you better whoever you meet.
It is always right whatever you do.
