I.状语从句
听录音材料导入所要复习的状语从句内容。（划线部分是学生根据录音所要填写的内容）
One day after work ,I was doing my housework when a man with thick glasses came to visit me. In the beginning, I looked him up and down as if he were a stranger to me. He felt so surprised that he said excitedly to me, “Can’t you recognize me? Do you remember one student who was taller than any other student in your class when you were in Shizhuang Middle School?” What he said reminded me that he was a classmate of mine. I couldn’t help shaking him by the hand, “Glad to see you.Be seated please.” After sitting he said to me, “Because I will be sent to work where my father worked ten years ago, I want to invite you to dinner this Sunday so that I can say goodbye to you and other classmates who work in the city. As long as you have time,please accept my invitation.”Although it happened that I had no time that Sunday,considering that it was hardly possible to see him again,I promised him.
（本篇听力材料将中学阶段所学的三种从句(名词性从句、定语从句、状语从句)都包括进去了，且重点突出了状语从句。材料中包括九种状语从句）。
状语从句几乎是每年高考必考的内容，在高考试题中加上其它从句的干扰，以及倒装句，强调句的介入，使得状语从句更为复杂。状语从句是一种副词性从句，通常由一个从属连词或一个起连词作用的词组引导。状语从句可以表示时间、地点、原因、目的、结果、条件、方式、让步和比较9种意义。
一、基本用法
1.时间状语从句
由下列连词引导：when, while , as, before, after, once, till, until, once, as soon as, now that, hardly…when, scarcely…when, no sooner…than,有一些表示时间的副词（短语）或名词短语也可引导时间状语从句。如：directly, instantly, immediately, by the time，the moment, the second, the minute, the instant, every time, each time, next time, the last time等
注意点如下：
1)when, while, as引导的时间状语从句
as表示“当……的时候”，往往和when/ while通用，但它着重强调主句与从句的动作或事情同时或几乎同时发生。
①She came up as I was cooking.(同时)
② When I was walking down the street, I came across an old friend of mine.我在街上行走时，碰到一位老朋友　　　　　　　　　　　　　
when(at or during the time that )既可以表示在某一点的时候，又可表示在某一段时间内，主句与从句的动作或事情可以同时发生也可以先后发生。
①It was raining when we arrived.(指时间点)
②When we were at school, we went to the library every day.(在一段时间内)
③When we arrived there, the film had already begun.(先后发生)
While强调一段时间里，仅表示从句和主句的动作同时发生，并且有延续意义，该从句中的动词一般要用延续性动词，从句中常用过去进行时态或一般过去时态；在when表示a period of time时，两者可以互换。
①Please don’t talk so loud while/when others are working. 其他人工作时请不要大声讲话。
②He fell asleep while/when reading. 读书时他睡着了。
③ While they were watching TV, I was preparing myself for the coming examination. 他们在看电视，而我在为即将到来的考试做准备。
Strike while the iron is hot.( 不可用as或when，这里的while意思是“趁……”)
as表示主从句动作同时发生，所以常译作＂一边…一边＂。
John sings as he works.
As his hands dropped he dropped with it, and I laid him down ,dead.
当When引出的时间状语从句为系表结构，而且其主语和主句的主语一致，其表语又是一个名词时，就可以用 as 引导的省略句来代替。
When he was a young man (= As a young man ) he was fond of hunting.
2)before状语从句的重点句型
It will (not ) be a period of time before 还要……才，要不了多久就……
Was (not) 过了……才 没多久就……
①It was a long time before I got to sleep . 过了好长时间我才睡着了。
② It wasn’t long before he told me about the news. 没多久他就告诉了我那条新闻。
③不等……就 在---之前：Before I could get in a word, he had measured me.
The telephone rang off before I could answer it. 我还没来得及接电话，电话就挂断了。
④刚……就：He hardly entered the room before he heard the telephone ring.
⑤先……再：You can have a few days to think about it before you make your decision.
做出决定之前你还有几天时间考虑
3)since 引导的从句用延续性动词的过去式（包括过去完成时），则从句的动作已经结束,从句意思是否定的。如果从句的动词是延续性动词的完成时态，从句意思是肯定的。
It is /has been a period of time 延续性动词的过去式 自从该动作结束已多长时间
延续性动词的完成时态 since 该动作已延续了多长时间
短暂性动词的过去式 自从该动作开始已多长时间
①He has never been to see me since I was ill.我病愈后，他一直未来看我。（不在生病了）
②He has never been to see me since I have been ill.我病了，他一直未来看我。
③I haven’t heard from him since he lived here.自从他这里搬走，我就没有收到他的信。（不住在这儿了）
④I know him very well since he has lived here near us.自他住在我们附近以来，我对他很了解。
⑤It’s three years since I was in the army.我退伍已三年了。（不在服役了）
⑥It’s three years since I have been in the army=It's three years since I joined the army.我入伍已三年了。
4)如果与till与until从句使用的主句是肯定的，则主句中谓语要用延续性动词如果与其使用的主句是否肯定的，则主句中谓语要用短暂性动词。另till从句不可以置于句首，只有until从句可以放在句首。not until 放在句首时主句要倒装。
He didn’t go back to his hometown until three years later.
=Not until three years later did he go back to his hometown.
I didn’t recognize him until he took off his glasses.
= Not until he took off his glasses did I recognize him.
2.原因状语从句
由下列连词引导：as, because, since, now that, considering that, seeing that(鉴于---)。
下面几点值得注意：
1) because语气最强，用于回答why的提问，可与强调词only, just 以及否定词not 连用。但不可以与so连用。如You shouldn’t get angry just because some people speak ill of you.
He failed because he was careless. 他因粗心而失败了。
because引导的从句可以被强调：
It was because she wanted to study abroad that she entered for TOEFL
2) since引导的从句语气次于because引导的从句，常表示稍加分析后而推断出的原因，或指人们已知的事实，比as正式一些,常置于句首。as语气最弱，其原因只是对结果的附带说明，一般放在句首。
Since/ Now that no one is against it ,let’s carry out the plan.
Since everyone has come, let’s begin our meeting. 既然大家都来了，我们开会吧。
As all the seats were full, he stood there. 所有的座位都满了他只好站那儿。
3) for虽解释为“因为”但只是一个并列连词，它也常引导句子表原因，但不是原因状语从句，它是一个并列句。for所提供的理由是一种补充性的说明，表推测的理由。
The day was short, for it was December.
It might have rained last night for the ground is wet. 昨晚可能下雨了，因为地面是湿的。
She must have cried for her eyes are red. 她一定哭过了，她眼睛红的。

Anywhere he went, he got warm welcome. 无论他走到哪儿，都收到热烈欢迎。
The girl takes the doll with her everywhere she goes.
Where there is a will, there is a way. 有志者事竟成。
4.结果状语从句
由下列连词引导：that，so…that，such…that，so that等。
注意以下几种结构：
1).so+adj/adv+that… 2).such(a/an+adj)+n+that…
3).so+adj+a/an+n+that=such a/an+adj+n+that… 4).so many/much/few/little(少)+n+that…
5)such +(adj) +n (u /pl )+ that

It was such a lovely day / so lovely a day that we all went swimming 今天天气如此的好，我们大家都去游泳了。
He gave such important reasons that he was excused. 他给了非常重要的理由，我们都原谅他了。
So或such置于句首时，主句常倒装。
It was such a lovely day / so lovely a day that we all went swimming .　
＝Such a lovely day was it that we all went swimming.
He gave such important reasons that he was excused.
= Such important reasons did he give that he was excused.
注意以上结构与定语从句so/such…as的区别。

That 引导的从句常用于口语中。

5.目的状语从句
由下列连词引导：so that, in order that, for fear that, in case等。 （注：so that也可用来引导结果状语从句）
so that, in order that引导的目的状语从句中常需用情态动词。so that引导的目的状语从句只能放在主句之后，in order that 引导的目的状语从句可以放在主句之前或之后。
We set out early so that we could see the sunrise. 我们很早出发以便能看到日出
He sent the letter by air mail so that it might reach them in time. 他空邮这份信的以便他们能按时收到。
for fear that, in case 引导的目的状语从句谓语动词要用should do 它们本身带有否定意义，相当于so that--not, in order that---not
