条件状语从句、时间状语从句、宾语从句的语法（要全）急急急!

你好,以下是你要的最全面的资料,对你定有帮助.
一. 时间状语从句:
学习状语从句的重点是连接从句的连词的选择,就比如时间状语从句吧.
The new secretary is supposed to report to the manager as soon as she________.
A.will arrive B.arrives C.is going to arrive D.is arriving
在时间状语从句中,当主句是将来时或含有情态动词时,从句通常用一般现在时代替将来时.选（B）每当他们遇到困难时,我们就去帮助他们.
We will go to help them whenever they meet with difficulties
可以引导时间状语从句的词很多,比如when ,wile,as等等.
When ,while,as的区别
I was reading a novel________he watching TV.
A.when B.while C.before D.as 2
While表示一段时间并表示对比,从句中不能用点动词；when还可以表示从句动作发生在主句动作之前或之后；as表示“一边.一边.”
While表示对比不只可以用在时间状语从句中.
Some people like coffee,while others like tea.有人喜欢咖啡,而有人则喜欢茶,强调了对比.When you have finished your work,you may have a rest.当你工作做完的时候,你可以休息一会儿.从句的finish发生前,才会有rest(休息)这个动作发生.在这种情况下,就只能用when,而不能用while或as,除此以外,when还有一点比较特殊.
When可以表示“那时突然”的意思,而其他两个词则还可以,比如说,我在看电视的时候,他突然进来了,就可以说：I was watching TV,When he suddenly came in.
As通常表示“一边...一边”的意思,比如我边洗碗边唱歌就可以说“As I was washing the dishes,I was singing songs.”另外,它还可以表示”“随时间推移”,这就是它的特殊之处了.
You will grow wiser as you grow older.
引导时间状语的从句还有before,after,once,until等.这个until的用法也需要注意,下面我们就来看看它该怎么用吧.
People don’t know the value of freedom________they have lost it.
A.until B.when C.since D.as
till和until表示“直到.才.”要和延续性动词连用,not….until是固定搭配.
Not….until……√ not….till,而且until可用于句首,而till通常不用于句首,比如：Until you told me,I had heard nothing of what happened.
直到你告诉我,我才知道出了什么事
还有几个连接时间状语从句的关联词,表示“一…..就.”的结构,他们是：as soon as,the moment,no sooner….than ,hardly/scarcely….when. Tony,这些关联词你用用吗?
值得注意的是这几个关联词的量才而为和语序的不同用法.量才而为上,as soon as和the moment所在的复合句中,主句和从句通常都用过去时,no sooner…..than和hardly/scarcely…when所在的复合句中,主句一般用过去时,而从句用过去完成时.
________had he gone to bed. ________he fell asleep.
A.The moment,/ B.No sooner,than C.When,hardly D.As soon as,/
当no sooner或者hardly在句首时,从句要倒装.
我刚一到家,就开始下雨了.
As soon as I got home,it began to rain.
The moment I got home,it began to rain.
I　had no sooner got home than it began to rain.
Hardly had I got home when it began to rain.
no sooner….than和hardly….when说一下,至少要一句倒装啊.
二、条件状语从句.
You will be late__________you leave immediately.
A.unless B.until C.if D.or
B.
Unless=if not. If you don’t leave immediately you will be late.
在条件状语从句中,如果主句是将来时或含有情态动词,从句通常用一般现在时代替将来时.这只有在时间和条件状语从句中才有这个用法.
条件状语从句还可以由as long as(只要),in case(以防),　on condition that(条件是)等词来引导.
You may do anything you like as long as it is not against the law.只要不犯法,你可以做任何你喜欢的事.
Take this umbrella with you in case it rains.带上这把十倍雨伞,以防下雨.
三、宾语从句
引导宾语从句时,whether和if一般可以互换.If和whether直接就可以引导宾语从句了,不用that了.
可是并不是在所有的宾语从句中if和whether都可以互换.它们也是有区别的.
如果出现or not则只能用whether.
比如：We don’t know whether he will come or not.我们不知道他是否会来.在这句话里只能用whether.
介词宾语从句只能用whether.
比如：That depends on whether he will come.那取决于他是否会来.
宾语从句还有和主语从句不一样的地方.我们看一看吧.
8.________ I should take part in the sports meet?
A.Do you think why B.Do you think when C.Do you think D.Do you think how
C
引导宾语从句的that在从句中不充当任何成分时,可以省略.
不过不是所有引导宾语从句的that都可以省略.
第一,如果有两个并列的由that引导的宾语从句由and或but连接,那么第一个that可以省略,但第二个that不能省略.
比如：He said(that)he liked to live in China and that he wouldn’ t leave for America.
他说他喜欢住在中国而不会去美国.
第二点是如果that引导的是介词宾语从句,则that不能省略.
例如：你的作文写得不错,只是有几个拼写错误.就应该说
Your composition is quite good except that are some spelling mistakes.
这里的that引导的从句作介词except的宾语,连接词that就不可以省略.
也就是说主语从句的that不可以省略,而宾语从句的that却在大多数情况下可以省略.
主语从句和宾语从句也有相同的地方.
名词性从句之间是有些共性的,下一个秘诀和主语从句的也很相似.
9 We think________important that college students should master at least one foreign language.
A.it B.him C.that D.what
A
主句的宾语是“宾语＋宾补”的复合宾语时,要用形式宾语it替代宾语从句,而将宾语从句置于宾补之后.
再比如：我认为所有的人都应该尊重老人,这是非常正确的.
I think it quite right that all of us should respedt the old.
10.I don’t think you are right,____?
A.aren’t you B.are you C.do I D.do you
B
这是通过反意疑问句来说明宾语从句的否定情况,动词think, believe, suppose, expect等词后面的宾语从句带有否定含义时,通常不否定宾语从句中的谓语,而是否定主句的谓语动词.
这种下的反意问句要根据从句的真正意思来提问.
再来练习一下.
我想他不会来 I don’t think he will come.
11.No one can be sure________in a million years.
A.what man will look like B.what will man look like
C.man will look like that D.what look will man like
A
Sure,afraid,glad,certain等形容词后面可以接宾语从句.
这几个形容词的后面通常都是接介词of的.
比如　I’m afraid of being late.如果转换成宾语从句就是I’m afraid that I’ll be late.
再比如　I am sure that you will come.我确信你会来.

状语从句可分为时间、地点、原因、目的、结果、方式、让步、条件和比较状语从句，其中有些连词可引导多种状语从句，表达不同的意义；也有某一从句可用多个连词引导，表达相同的意义，这就使得状语从句成为一大难点，下面就容易引起混淆的引导词作简要介绍。
一、while while常表示“当……的时候；然而；尽管”。
如：The students were busy taking ...
