I.狀語從句
聽錄音材料導(dǎo)入所要復(fù)習(xí)的狀語從句內(nèi)容。（劃線部分是學(xué)生根據(jù)錄音所要填寫的內(nèi)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.
（本篇聽力材料將中學(xué)階段所學(xué)的三種從句(名詞性從句、定語從句、狀語從句)都包括進(jìn)去了，且重點(diǎn)突出了狀語從句。材料中包括九種狀語從句）。
狀語從句幾乎是每年高考必考的內(nèi)容，在高考試題中加上其它從句的干擾，以及倒裝句，強(qiáng)調(diào)句的介入，使得狀語從句更為復(fù)雜。狀語從句是一種副詞性從句，通常由一個從屬連詞或一個起連詞作用的詞組引導(dǎo)。狀語從句可以表示時間、地點(diǎn)、原因、目的、結(jié)果、條件、方式、讓步和比較9種意義。
一、基本用法
1.時間狀語從句
由下列連詞引導(dǎo)：when, while , as, before, after, once, till, until, once, as soon as, now that, hardly…when, scarcely…when, no sooner…than,有一些表示時間的副詞（短語）或名詞短語也可引導(dǎo)時間狀語從句。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
注意點(diǎn)如下：
1)when, while, as引導(dǎo)的時間狀語從句
as表示“當(dāng)……的時候”，往往和when/ while通用，但它著重強(qiáng)調(diào)主句與從句的動作或事情同時或幾乎同時發(fā)生。
①She came up as I was cooking.(同時)
② When I was walking down the street, I came across an old friend of mine.我在街上行走時，碰到一位老朋友
when(at or during the time that )既可以表示在某一點(diǎn)的時候，又可表示在某一段時間內(nèi)，主句與從句的動作或事情可以同時發(fā)生也可以先后發(fā)生。
①It was raining when we arrived.(指時間點(diǎn))
②When we were at school, we went to the library every day.(在一段時間內(nèi))
③When we arrived there, the film had already begun.(先后發(fā)生)
While強(qiáng)調(diào)一段時間里，僅表示從句和主句的動作同時發(fā)生，并且有延續(xù)意義，該從句中的動詞一般要用延續(xù)性動詞，從句中常用過去進(jìn)行時態(tài)或一般過去時態(tài)；在when表示a period of time時，兩者可以互換。
①Please don’t talk so loud while/when others are working. 其他人工作時請不要大聲講話。
②He fell asleep while/when reading. 讀書時他睡著了。
③ While they were watching TV, I was preparing myself for the coming examination. 他們在看電視，而我在為即將到來的考試做準(zhǔn)備。
Strike while the iron is hot.( 不可用as或when，這里的while意思是“趁……”)
as表示主從句動作同時發(fā)生，所以常譯作＂一邊…一邊＂。
John sings as he works.
As his hands dropped he dropped with it, and I laid him down ,dead.
當(dāng)When引出的時間狀語從句為系表結(jié)構(gòu)，而且其主語和主句的主語一致，其表語又是一個名詞時，就可以用 as 引導(dǎo)的省略句來代替。
When he was a young man (= As a young man ) he was fond of hunting.
2)before狀語從句的重點(diǎn)句型
It will (not ) be a period of time before 還要……才，要不了多久就……
Was (not) 過了……才 沒多久就……
①It was a long time before I got to sleep . 過了好長時間我才睡著了。
② It wasn’t long before he told me about the news. 沒多久他就告訴了我那條新聞。
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. 我還沒來得及接電話，電話就掛斷了。
④剛……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.
做出決定之前你還有幾天時間考慮
3)since 引導(dǎo)的從句用延續(xù)性動詞的過去式（包括過去完成時），則從句的動作已經(jīng)結(jié)束,從句意思是否定的。如果從句的動詞是延續(xù)性動詞的完成時態(tài)，從句意思是肯定的。
It is /has been a period of time 延續(xù)性動詞的過去式 自從該動作結(jié)束已多長時間
延續(xù)性動詞的完成時態(tài) since 該動作已延續(xù)了多長時間
短暫性動詞的過去式 自從該動作開始已多長時間
①He has never been to see me since I was ill.我病愈后，他一直未來看我。（不在生病了）
②He has never been to see me since I have been ill.我病了，他一直未來看我。
③I haven’t heard from him since he lived here.自從他這里搬走，我就沒有收到他的信。（不住在這兒了）
④I know him very well since he has lived here near us.自他住在我們附近以來，我對他很了解。
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)如果與till與until從句使用的主句是肯定的，則主句中謂語要用延續(xù)性動詞如果與其使用的主句是否肯定的，則主句中謂語要用短暫性動詞。另till從句不可以置于句首，只有until從句可以放在句首。not until 放在句首時主句要倒裝。
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.原因狀語從句
由下列連詞引導(dǎo)：as, because, since, now that, considering that, seeing that(鑒于---)。
下面幾點(diǎn)值得注意：
1) because語氣最強(qiáng)，用于回答why的提問，可與強(qiáng)調(diào)詞only, just 以及否定詞not 連用。但不可以與so連用。如You shouldn’t get angry just because some people speak ill of you.
He failed because he was careless. 他因粗心而失敗了。
because引導(dǎo)的從句可以被強(qiáng)調(diào)：
It was because she wanted to study abroad that she entered for TOEFL
2) since引導(dǎo)的從句語氣次于because引導(dǎo)的從句，常表示稍加分析后而推斷出的原因，或指人們已知的事實(shí)，比as正式一些,常置于句首。as語氣最弱，其原因只是對結(jié)果的附帶說明，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. 既然大家都來了，我們開會吧。
As all the seats were full, he stood there. 所有的座位都滿了他只好站那兒。
3) for雖解釋為“因?yàn)椤钡皇且粋�并列連詞，它也常引導(dǎo)句子表原因，但不是原因狀語從句，它是一個并列句。for所提供的理由是一種補(bǔ)充性的說明，表推測的理由。
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?yàn)榈孛媸菨竦摹?/p>
She must have cried for her eyes are red. 她一定哭過了，她眼睛紅的。
He can’t have done that for he is not that kind of man. 他不可能這么做的，因?yàn)樗皇悄欠N人。

Where there is a will, there is a way. 有志者事竟成。
4.結(jié)果狀語從句
由下列連詞引導(dǎo)：that，so…that，such…that，so that等。
注意以下幾種結(jié)構(gòu)：
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 .
＝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.
注意以上結(jié)構(gòu)與定語從句so/such…as的區(qū)別。

This is such an interesting/so interesting a film as everyone wants to see.

That 引導(dǎo)的從句常用于口語中。

5.目的狀語從句
由下列連詞引導(dǎo)：so that, in order that, for fear that, in case等。 （注：so that也可用來引導(dǎo)結(jié)果狀語從句）
so that, in order that引導(dǎo)的目的狀語從句中常需用情態(tài)動詞。so that引導(dǎo)的目的狀語從句只能放在主句之后，in order that 引導(dǎo)的目的狀語從句可以放在主句之前或之后。
We set out early so that we could see the sunrise. 我們很早出發(fā)以便能看到日出
He sent the letter by air mail so that it might reach them in time. 他空郵這份信的以便他們能按時收到。
for fear that, in case 引導(dǎo)的目的狀語從句謂語動詞要用should do 它們本身帶有否定意義，相當(dāng)于so that--not, in order that---not

Please remind me of it again tomorrow in case I forget. 明天請?jiān)俅翁嵝盐乙苑牢彝恕?/p>
