二、表示条件(条件状从)
If（假如，如果）
unless（除非）
as long as (只要)
考点
2、“祈使句 + and (or)+ 陈述句” 在意思上相当于一个带有条件状语从句的复合句。
1、主将从现：
在条件状语从句里，谓语动词通常用现在时态表示将来的动作或状态。
1.He won’t be late unless he is ill.
2.What shall we do if it snows tomorrow
（假如，如果）
注：I don’t know if it will snow tomorrow (宾从：if 是否)
1.Hurry up, or you’ll be late.
=If you don’t hurry up, you’ll be late.
Study hard and you will pass the exam.
=If you study hard, you will pass the exam.
三、表示原因(原因状从)
because
since（既然，由于,句首）
as(鉴于，由于)
eg.
He didn’t come to school because he was ill.
As it is raining, we shall not go the zoo.
Since you can’t answer the question, I’ll ask someone else.
1. because表示直接原因，语气最强。Because引导的原因状语从句多放在主句之后。回答由why提出的问题，只能用because。
Why aren’t going there ------Because I don’t want to.
As和since语气较弱，一般用来表示明显的原因。由as和since引导的原因状语从居多放在句首。例如：
As he has no car, he can’t get there easily.
Since we have no money, we can’t buy it.
2. because和so不能同用在一个句子里。
考点
四、表示目的(目的状从)
so that（以便）
in order that（为了）
eg.
We started early so that we could catch the first train.
He studies hard so that he could work better in the future.
We used the computer in order that we might save time.
so that既可引导目的状语从句，又可引导结果状语从句。区别这两种从句的办法有两个：
1)目的状语从句里往往带有情态动词can, could, may, might等。
2)从意思上看，目的状语从句往往表示的目的很明确。例如：
Speak clearly so that they may understand you. (目的状语从句)
Jack is badly ill so that he has to rest. (结果状语从句)
考点
五、表示结果（结果状从）
so…that
such…that
so that
eg.
He is so poor that he can’t buy a bike for his son.
She is such a good girl that everybody likes her.
My pencil fell under the desk, so that I couldn’t see it.
so...that引导的结果状语从句中，so是副词，
结构： so+aj/adv+that
He was so glad that he couldn’t say a word.
The hall is so big that it can hold 2,000 people.
Mother lives so far away that we hardly ever see her.

It was （） wonderful a film that all of us wanted to see it again.
The film was () wonderful that all of us wanted to see it again.
注意：
1.有时上述两种结构是可以互换（可数名词单数）。
特殊考点1
2.如果名词前由many, much, little, few等词修饰时（数量：多多少少），只能用so, 不用such。例如：
Soon there were so many deer that they ate up all the wild roses.
He has so little time that he can’t go to the cinema with you.
注：she is () a little girl.
Such (小的)

although/though（虽然）
no matter….（无论…）
even if/ even though （即使）
eg.

Although I am tired, I must go on working.
No matter how late you come, I’ll wait for you.
=However late you come, I’ll wait for you.
No matter what=whatever
no matter when=whenever who/which/where
1. although/though（虽然），no matter….（无论…）, even if/ even though（即使）等连词不能与but连用，但可以和yet/still连用。例如：
Eg. Though it was raining hard, but he still went out.（x）
应该说：Though it was raining hard, he still went out.
或It was raining hard, but he still went out.
