常用虚拟语气，表示不存在的动作或状态。

e.g. It sounds as if/though somebody was knocking at the door.
2) 主语 +连系动词（ look/seem/appear ） +that/as if
语气 ( 主句一般现在时 , 从句就用过去式，
时 ) 。 It looks as if he were her own
father.(
Dark clouds are gathering. It looks as if it
As /as if 、 as though

The situation is not ____ it seems to be.



从句
*as if/as though引导的表语从句如果是事实，就用陈述语气；如果与事实不符，就用虚拟

because 引导表语从句 通常只用于 “ This/That/It is because

”结构中。


’ t written to me for a long time.
My anger is because you haven
你为什么不来出席座谈会？是病了么？
Why were you absent from the forum? Was it because you were ill?
, why与because引导表语从句时的区别
1）虽然三者均可引导表语从句，但that没有词义，而





why

和

because

有自己的意思；


另外，虽然why 和 because都可引导表语从句，但前者强调结果，后者强调原因。如：
The reason was ____ you don’ t trust her.原因是你不信任她。




The fact is ____ they are angry with each other.
He was ill. That’ s ____ he was sent to the hospital.


事实是他们生彼此的气。
他病了，所以被送到医院来。

He was sent to the hospital. That





’ s ____ he was ill.他被送到医院，是因为他生病了。






填空 : The reason why we didn't trust him is ______ he has often
lied
*reason 做主语时，表语从句只能用that引导 , 不能用
why
The reason (why/for)is /was that.


．
引导。句型结构为：



The reason is that


他早上来晚的原因是他晚了一分钟而没赶上火车。
The reason ____ he was late was ____ he missed the train by one minute this morning







（当主语是reason 时，表语从句要用that引导而不是because ）
注意点 1：主语为 reason时，表语从句连接词用that,但以 it,
this,
句子，则可用because 。
The reason for his being late was ____ he missed the early bus.
She was late this morning. That was ____ she missed the early bus.




















that

开头做主语的

* The reason


why he was late was ____ he missed the early bus.
（ why 引同位语从句）
例题 2：




The reason why he failed is ________he was too careless.



A. because B. that C. for D. because of





注意点 2：主句主语为 reason,that 引导表语从句，不可用


只能用

because.B



that/what
的区别

； how you are C. How ； that you are D. What
；
