1、狀語從句狀語從句狀語從句用來修飾主句中的動詞，副詞和形容詞的從句叫狀語從句。根據(jù)其含義狀語從句可分為時間狀語從句，地點狀語從句，條件狀語從句，原因狀語從句，結(jié)果狀語從句，比較狀語從句，目的狀語從句，讓步狀語從句。1 .時間狀語從句（1）時間狀語從句常用 when, as, while, before, after, since, till, until, as soon as 等連詞來引導(dǎo)。例如：It was raining hard （rain hard 下大雨）when got to school yesterday.While he was doing his homework, the

2、 telephone rang.As he walked along （沿著走）the lake, he sang happily.He had learned a little Chinese before he came to China.After he finished middle school, he went to work in a factory.（2）在時間狀語從句里，通常不用將來時態(tài)，用現(xiàn)在時態(tài)表示將來的動作或狀態(tài)。例如：I ' ll ring you up as soon as I get to New York.I will tell him everythi

3、ng when he comes back.He won ' t believe it until he sees it with his own eyes.在帶有till或until引導(dǎo)的時間狀語從句的主從復(fù)合句里，如果主句用肯定式，其含義是直到時”，謂語動詞只能用延續(xù)性動詞。如果主句用否定式，其含義是 直到才”，在以前不”，謂語 動詞可用瞬間動詞。例如：The young man read till the light went out （熄滅）Let ' s wait until the rain stops.We won' t start until Bob c

4、omes.Don' t get off（從下來）until the bus stops.Till是指直到某一特定事件發(fā)生的時候，而在那個時刻之后，該事情或狀況仍將持續(xù)。Until是指直到某一特定事件發(fā)生的時候，而講話的人在自己心里認(rèn)為，在那個時刻之后，該事情或該狀況將中止 （不怎么可能持續(xù)）。固定組合里from morning tillnight, till/until是不能替換的，】2 .條件狀語從句（1）條件狀語從句通常由if, unless引導(dǎo)。例如:What shall we do if it snows tomorrow?Don' t leave the buildi

5、ng unless I tell you to.(2)在條件狀語從句里，謂語動詞通常用現(xiàn)在時態(tài)表示將來的動作或狀態(tài)。例如：I ' ll help you with your English if am free tomorrow.He won ' t be late unless he is ill.(3)祈使句+ and (or)+陳述句”在意思上相當(dāng)于一個帶有條件狀語從句的復(fù)合句。例如：Hurry up, or you ' ll be late. =If you don' t hurry up, you ' ll be late.Study hard

6、 and you will pass the exam. =If you study hard, you will pass the exam.3 .原因狀語從句(1)原因狀語從句通常由because, since, as引導(dǎo)。例如：He didn ' t come to school because he was ill.As it is raining, we shall not(不得； 不應(yīng)該)go the zoo.Since you can ' t answer the question, I' ll ask someone else.(2)because表示直

7、接原因，語氣最強。Because引導(dǎo)的原因狀語從句多放在主句之后。回答由why提出的問題,只能用because As和since語氣較弱，一般用來表示明顯的原因。由 as和since引導(dǎo)的原因狀語從居多放 在句首。例如：Why aren ' t going there?Because I don ' t want to.As he has no car, he can ' t get there easily.Since we have no money, we can ' t buy it.(3)because和so不能同用在一個句子里。4 .結(jié)果狀語從句(1

8、)結(jié)果狀語從句由 sothat, such that, soihat。例如：He is so poor that he can ' t buy a bike for his son.t see it.She is such a good teacher that everybody likes her.My pencil fell under the desk, so that I couldn（2）so由曲suchthat可以互換。例如：在由sothat引導(dǎo)的結(jié)果狀語從句中，so是副詞，與形容詞連用。其結(jié)構(gòu)是：so +形容詞（副詞）+ that +從句”。例如：He was so g

9、lad 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 （幾乎不，從來不）see her.在由suchthat引導(dǎo)的結(jié)果狀語從句中，such是形容詞，它修飾的可以是單數(shù)或復(fù)數(shù)可數(shù)名詞，也可以是不可數(shù)名詞；名詞前面可以帶形容詞，也可不帶。如果是單數(shù)可數(shù)名詞，前面需加不定冠詞a或an。例如：It was such a hot day that nobody wanted to do anythi

10、ng.He had such long arms that he could almost touch the ceiling.（天花板）He made such rapid progress that he did very well in the mid -term.有時上述兩種結(jié)構(gòu)是可以互換的。例如：It was such a wonderful film that all of us wanted to see it again.=The film was so wonderful that all of us wanted to see it again.It is such an

11、important match that nobody wants to miss it.=The match is so important that nobody wants to miss it.（3）如果名詞前由 many, much, little, few等詞修飾時，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 tothe 電nema with you.5 .比較狀語從句比較狀

12、語從句通常由as- as,比較級+ than 等連詞引導(dǎo)。例如：Tom runs faster than John does.This classroom is as big as that one.6 .目的狀語從句（1）目的狀語從句通常由so that, in order that （為了,以便）引導(dǎo)。例如：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 orde

13、r that we might save time.（2）so that既可引導(dǎo)目的狀語從句，又可引導(dǎo)結(jié)果狀語從句。區(qū)別這兩種從句的辦法有兩個：1）目的狀語從句里往往帶有情態(tài)動詞 can, could, may, might等。2）從意思上看，目的狀語從句往往表示的目的很明確。例如：Speak clearly so that they may understand you.（目的狀語從句 ）Jack is badly ill so that he has to rest.（結(jié)果狀語從句）7 .讓步狀語從句讓步狀語從句通常由although, though等連詞引導(dǎo)。例如：Though he i

14、s young, he knows a lot.Although I am tired, I must go on working.（2）although（though）不能用在同一個句子中。例如：我們不能說： Though it was raining hard, but he still went out.應(yīng)該說： Though it was raining hard, he still went out. 或 It was raining hard, but he still went out.8 .地點狀語從句地點狀語從句常常由where來引導(dǎo)。例如：Go where you like

15、.Where there is a will, there is a way.總結(jié)：狀語從句分類及常用連詞：類別連詞時間狀語從句when, whenever, while, as, before, after, since, till, once （旦）地點狀語從句where, wherever原因狀語從句because, since, as, for, now that （既然，由于） etc. （ et cetera, 等于 and so on）目的狀語從句in order that（為了,以便）,so that, that, etc.結(jié)果狀語從句so that, so that, suc

16、hthat, that, etc.條件狀語從句if, unless, as（so）long as, etc.讓步狀語從句though, although, even if, even though, however, whatever, as, etc.比較狀語從句as - as, so - as, than, etc.方式狀語從句as, as if, as though, etc.練習(xí)一一.單項填空1. he ' s old, he can still carry this heavy bag.A.
