中考復(fù)習(xí)資料 狀語(yǔ)從句狀語(yǔ)從句用來(lái)修飾主句中的動(dòng)詞，副詞和形容詞的從句叫狀語(yǔ)從句。根據(jù)其含義狀語(yǔ)從句可分為時(shí)間狀語(yǔ)從句，地點(diǎn)狀語(yǔ)從句，條件狀語(yǔ)從句， 原因狀語(yǔ)從句，結(jié)果狀語(yǔ)從句，比較狀語(yǔ)從句，目的狀語(yǔ)從句，讓步狀語(yǔ)從句。1.時(shí)間狀語(yǔ)從句(1)時(shí)間狀語(yǔ)從句常用when, as, while, before, after, since, till, until, as soon as等連詞來(lái)引導(dǎo)。例如：It was raining hard 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(shí)間狀語(yǔ)從句里，通常不用將來(lái)時(shí)態(tài)，用現(xiàn)在時(shí)態(tài)表示將來(lái)的動(dòng)作或狀態(tài)。例如：Ill ring you up 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(shí)間狀語(yǔ)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(yǔ)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(yǔ)動(dòng)詞可用瞬間動(dòng)詞。例如：The young man read till the light went out.Lets wait until the rain stops.We wont start until Bob comes.Dont get off until the bus stops.2. 地點(diǎn)狀語(yǔ)從句地點(diǎn)狀語(yǔ)從句常常由where來(lái)引導(dǎo)。例如：Go where you like.Where there is a will, there is a way.3.原因狀語(yǔ)從句(1)原因狀語(yǔ)從句通常由because, since, as，for引導(dǎo)。例如：He didnt come to school because he was ill.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(yǔ)氣最強(qiáng)。Because引導(dǎo)的原因狀語(yǔ)從句多放在主句之后?；卮鹩蓋hy提出的問(wèn)題，只能用because。As和since語(yǔ)氣較弱，一般用來(lái)表示明顯的原因，所表示的語(yǔ)氣由becausesinceasfor逐漸減弱。由as和since引導(dǎo)的原因狀語(yǔ)從居多放在句首，for放句中，補(bǔ)充說(shuō)明原因。例如：-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.You cant see the teacher,for he isnt in.(3)because和so不能同用在一個(gè)句子里。4.條件狀語(yǔ)從句(1)條件狀語(yǔ)從句通常由if, unless引導(dǎo)。例如：What shall we do if it snows tomorrow?Dont leave the building unless I tell you to.(2)在條件狀語(yǔ)從句里，謂語(yǔ)動(dòng)詞通常用現(xiàn)在時(shí)態(tài)表示將來(lái)的動(dòng)作或狀態(tài)。例如：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” 在意思上相當(dāng)于一個(gè)帶有條件狀語(yǔ)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.5.目的狀語(yǔ)從句(1)目的狀語(yǔ)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 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(yǔ)從句，又可引導(dǎo)結(jié)果狀語(yǔ)從句。區(qū)別這兩種從句的辦法有兩個(gè)：1)目的狀語(yǔ)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(yǔ)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(yǔ)從句)Jack is badly ill so that he has to rest.(結(jié)果狀語(yǔ)從句)6. 讓步狀語(yǔ)從句(1)讓步狀語(yǔ)從句通常由although, though，even 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.Even though you say so, I do not believe it.(2)although(though)和but不能用在同一個(gè)句子中。例如：我們不能說(shuō)：Though it was raining hard, but he still went out.應(yīng)該說(shuō)：Though it was raining hard, he still went out.或It was raining hard, but he still went out.7.比較狀語(yǔ)從句比較狀語(yǔ)從句通常由asas, 比較級(jí) + than等連詞引導(dǎo)。例如：Tom runs faster than John does.He runs as fast as I do. 8. 結(jié)果狀語(yǔ)從句(1)結(jié)果狀語(yǔ)從句由sothat, suchthat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.(2) 在由so.that引導(dǎo)的結(jié)果狀語(yǔ)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.(3) 在由suchthat引導(dǎo)的結(jié)果狀語(yǔ)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。其結(jié)構(gòu)是：such+(a/an)+adj.+n. 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.(4) 有時(shí)sothat語(yǔ)such.that可以互換。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 important match that nobody wants to miss it.=The match is so important that nobody wants to miss it.(5)如果名詞前由many, much, little, few等詞修飾時(shí)，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 cant go to the cinema with you.但，若little表示“小”的意思時(shí)，應(yīng)用such.It is such a little sheep that it cant be left alone.九. 方式狀語(yǔ)從句方式狀語(yǔ)從句由 as引導(dǎo)。eg:Do as Romans do. 入鄉(xiāng)隨俗Do as I told you. 如我告訴你那樣做。Do as you like. 按你喜歡的方式去做。【實(shí)例解析】1.
