1、八年級(jí)下冊(cè)狀語從句講解及練習(xí)八年級(jí)下冊(cè)狀語從句講解及練習(xí)八年級(jí)下冊(cè)狀語從句講解及練習(xí)V:1.0精細(xì)整理，僅供參考 八年級(jí)下冊(cè)狀語從句講解及練習(xí)日期：20 xx年X月狀語從句用來修飾主句中的動(dòng)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(shí)間狀語從句，地點(diǎn)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(shí)間狀語從句(1)時(shí)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)。.It was raining hard when got

2、to school yesterday.While he was doing his homework, the telephone rang.(2)在時(shí)間狀語從句里，通常不用將來時(shí)態(tài)，用現(xiàn)在時(shí)態(tài)表示將來的動(dòng)作或狀態(tài)。.Ill ring you up as soon as I get to New York.(3)在帶有till或until引導(dǎo)的時(shí)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(shí)”，謂語動(dòng)詞只能用延續(xù)性動(dòng)詞。如果主句用否定式，其含義是“直到才”, “在以前不”, 謂語動(dòng)詞可用瞬間動(dòng)詞。.The young man read till the light went

3、out.Lets wait until the rain stops.2. 條件狀語從句(1)條件狀語從句通常由if, unless引導(dǎo)。.What shall we do if it snows tomorrow?Dont leave the building unless I tell you to.(2)在條件狀語從句里，謂語動(dòng)詞通常用現(xiàn)在時(shí)態(tài)表示將來的動(dòng)作或狀態(tài)。.Ill help you with your English if am free tomorrow.He wont be late unless he is ill.(3)“祈使句 + and (or)+ 陳述句” 在意思

4、上相當(dāng)于一個(gè)帶有條件狀語從句的復(fù)合句。.：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)。.He didnt come to school because he was ill.As it is raining, we shall not go the zoo.Since

5、you cant answer the question, Ill ask someone else.(2)because表示直接原因，語氣最強(qiáng)。Because引導(dǎo)的原因狀語從句多放在主句之后?；卮鹩蓋hy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。.-Why arent going there?-Because I dont want to.As he has no car, he cant get there easily.Since we have no money, we cant buy it.(

6、3)because和so不能同用在一個(gè)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)。.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.that可以互換。.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 +

7、形容詞（副詞）+ that + 從句”。 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.5. 比較狀語從句比較狀語從句通常由asas, 比較級(jí) + than等連詞引導(dǎo)。.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

8、that, in order that引導(dǎo)。.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 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(gè)：1)目的狀語從句里往往帶有情態(tài)動(dòng)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

9、很明確。.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(1)讓步狀語從句通常由although, though等連詞引導(dǎo)。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(gè)句子中。.我們不能說：Though it was raining hard, but h
