　　II.狀語從句

　　狀語從句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。

　　1.時(shí)間狀語從句

　　由下列連詞引導(dǎo)：when,while,as,before,after,once,till,until,since,as soon as,now that,hardly…when,

　　scarcely…when,no sooner…than,有一些表示時(shí)間的副詞(短語)或名詞短語也可引導(dǎo)時(shí)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

　　重點(diǎn)內(nèi)容如下：

　�、賥hen,while,as引導(dǎo)的時(shí)間狀語從句

　　▲as表示“當(dāng)……的時(shí)候”，往往和when/ while通用，但它著重強(qiáng)調(diào)主句與從句的動(dòng)作或事情同時(shí)或幾乎同時(shí)發(fā)生。

　　She came up as I was cooking.(同時(shí))

　　The runners started as the gun went off.(幾乎同時(shí))

　　▲when(at or during the time that )既可以表示在某一點(diǎn)的時(shí)候，又可表示在某一段時(shí)間內(nèi)，主句與從句的動(dòng)作或事情可以同時(shí)發(fā)生也可以先后發(fā)生。

　　It was raining when we arrived.(指時(shí)間點(diǎn))

　　When we were at school, we went to the library every day.(在一段時(shí)間內(nèi))

　　When we arrived there,the film had already begun.(先后發(fā)生)

　　▲while意思是“當(dāng)……的時(shí)候”或“在某一段時(shí)間里”。主句中的動(dòng)作或事情在從句中的動(dòng)作或事情的進(jìn)展過程中發(fā)生，從句中的動(dòng)詞一般要用延續(xù)性動(dòng)詞。在when表示a period of time時(shí)，兩者可以互換。

　　Please don’t talk so loud while/when others are working.

　　He fell asleep while/when reading.

　　Strike while the iron is hot.( 不可用as或when，這里的while意思是“趁……”)

　　②before狀語從句的重點(diǎn)句型

　　▲……之后……才：It was a long time before I got to sleep .

　　▲不多久……就：It wasn’t long before he told me about the affair.

　　▲不等……就：Before I could get in a word, he had measured me.

　　▲剛……就：He hardly entered the room before he heard the telephone ring.

　　▲先……再：You can have a few days to think about it before you make your decision.

　�、踫ince 引導(dǎo)的從句用延續(xù)性動(dòng)詞的過去式(包括過去完成時(shí))，則從句的動(dòng)作已經(jīng)結(jié)束,從句意思是否定的。如果從句的動(dòng)詞是延續(xù)性的用完成時(shí)態(tài)，從句意思是肯定的。

　　▲He 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)

　　▲He has never been to see me since I have been ill.我病了，他一直未來看我。

　　▲I 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)

　　▲I know him very well since he has lived here near us.自他住在我們附近以來，我對(duì)他很了解。

　　▲It’s three years since I was in the army.我退伍已三年了。(不在服役了)

　　▲It’s three years since I have been in the army=It's three years since he joined the army.

　　我入伍已三年了。

　�、苋绻ctill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(dòng)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(dòng)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(shí)主句要倒裝。

　　2.原因狀語從句

　　由下列連詞引導(dǎo)：as(由于),because(因?yàn)?, since(既然),now (that) (既然), considering that(顧及到), seeing that(由于)。

　　I do it because I like it.因?yàn)槲蚁矚g我才干。(because不能與 so連用)

　　He couldn’t have seen me, because I was not there.他不可能見過我，因?yàn)楫?dāng)時(shí)我不在那兒。

　　Seeing (that) quite a few people were absent, we decided to put the meeting off.

　　由于好些人都沒到會(huì)，我們決定延期開會(huì)

　　Now that/Since you are all here, let’s try and reach a decision.

　　既然大家都來了咱們就設(shè)法做一個(gè)決定吧

　　As she was ill, she didn’t come to the party.

　　由于病了，她沒來參加晚會(huì)。

　　Considering that they are just beginners, they are doing quite a good job.

　　考慮到他們才剛剛學(xué)做，他們干得算很不錯(cuò)的了。

　　重點(diǎn)內(nèi)容如下：

　�、賐ecause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.另外注意與not連用時(shí)否定的轉(zhuǎn)移。He didn’t do such a thing because he was afraid of his wife.他并不是因?yàn)榕滤钠拮硬抛鲞@樣的事。

　　Cf:He didn’t do such a thing,because he was afraid of his wife.因?yàn)榕缕拮�，他沒有做這樣的事。

　　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

　　②as語氣較弱，since語氣也較弱，但比as正式一些,所說明的原因比較明顯或是已知的事實(shí)，多用于口語中，所以不應(yīng)該強(qiáng)調(diào)。常置于句首。

　　As all the seats were full,he stood there.

　　Since you are going,I’ll go,too.

　　③for雖解釋為“因?yàn)?rdquo;但只是一個(gè)并列連詞，它引導(dǎo)的是并列句，不是原因狀語從句。

　　The day was short,for it was December.

　　3.地點(diǎn)狀語從句

　　由下列連詞引導(dǎo):where,wherever,anywhere,everywhere。

　　Anywhere he went,he got warm welcome.

　　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。

　　You’d better make a mark where you have any questions.

　　哪兒有問題，你最好在哪兒做個(gè)記號(hào)。(這里where引導(dǎo)的從句不是定語從句)

　　4.結(jié)果狀語從句

　　由下列連詞引導(dǎo)：that，so…that，so that(從句中不帶情態(tài)動(dòng)詞)，such…that，with the result that等。

　　注意以下幾種結(jié)構(gòu)：

　�、賡o+adj/adv+that…

　�、趕uch(a/an+adj)+n+that…

　　③so+adj+a/an+n+that=such a/an+adj+n+that…

　�、躶o many/much/few/little(少)+n+that…

　　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 that/as everyone wants to see it/(it).

　　He didn’t plan his time well so that/so he didn’t finish the work in time.

　　I had so little money then that I couldn’t afford a little present.

　　我當(dāng)時(shí)囊中羞澀連一份小小禮物都買不起

　　5.目的狀語從句

　　由下列連詞引導(dǎo)：so that,in order that,for fear that等。目的狀語從句的謂語動(dòng)詞常與情態(tài)動(dòng)詞can, could, may, might, should連用目的狀語從句的謂語動(dòng)詞常與情態(tài)動(dòng)詞can, could, may, might, should連用。

　　(so that也可用來引導(dǎo)結(jié)果狀語從句，但從句中不帶情態(tài)動(dòng)詞)

　　Let’s take the front seats (so) that we may see more clearly.

　　我們坐前排吧，這樣我們看得更清楚些。

　　6.條件狀語從句

　　分為真實(shí)條件句和非真實(shí)條件句(用在虛擬語氣中)。

　　表示條件的狀語從句可以由if(如果),unless(除非), in case(萬一), so /as long as(只要), as/ so far as(就……而言), on condition that(條件是……)suppose(假設(shè))supposing(假設(shè))(僅用在問句中)
