2、when got to school yesterday.While he was doing his homework, the telephone rang.As he walked along 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：Ill ring you up

3、as soon as I get to New York.I will tell him everything when he comes back.He wont believe it until he sees it with his own eyes.(3)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“一直到時”，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.Lets wait until the

5、unless he is ill.(3)“祈使句 + and (or)+ 陳述句” 在意思上相當于一個帶有條件狀語從句的復(fù)合句。例如： Hurry up, or youll be late.=If you dont hurry up, youll be late.Study hard 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 didnt come to school because he was ill

6、.As it is raining, we shall not go the zoo.Since you cant answer the question, Ill ask someone else.(2)because表示直接原因，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 arent going there?-Because I dont want to.As he has no car, he cant get th

7、ere easily.Since we have no money, we cant 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)結(jié)果狀語從句由sothat, suchthat, so that引導(dǎo)。例如：He is so poor that he cant buy a bike for his son.She is such a good teacher that everybody likes her.My pencil fell under the desk, so that I couldnt see it.(2)sothat語such.tha

8、t可以互換。例如：在由so.that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 glad that he couldnt say a word.The hall is so big that it can hold 2,000 people.Mother lives so far away that we hardly ever 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)

9、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 anything.He had such long arms that he could almost touch the ceiling.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

10、was so wonderful that all of us wanted to see it again.It is such an 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

11、little time that he cant go to the cinema with you.5. 比較狀語從句比較狀語從句通常由asas, 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引導(dǎo)。例如：We started early so that we could catch the first train.He studies hard so that he could

12、 work better in the future.We used the computer in order 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

13、)7. 讓步狀語從句(1)讓步狀語從句通常由although, though等連詞引導(dǎo)。例如：Though he is 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 we
