（通用版）2019中考英語二輪復(fù)習(xí) 狀語從句講義2

狀語從句學(xué)員姓名： 年 級(jí)： 輔導(dǎo)科目：英語 學(xué)科教師：授課日期授課時(shí)段授課主題狀語從句 教學(xué)內(nèi)容課前回顧知識(shí)梳理知識(shí)點(diǎn)1：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)。例如：It was raining hard when he 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)。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。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. 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?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)。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.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(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。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.(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)。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.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 + 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)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(shí)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 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(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.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)。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 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(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(gè)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(diǎn)狀語從句     地點(diǎn)狀語從句常常由where來引導(dǎo)。例如：Go where you like.     Where there is a will, there is a way.課堂小練（ ）5.
