狀語從句 狀語從句用來修飾主句中的動(dòng)詞匯總

1、狀語從句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)。例如：It was raining hard（rain hard 下大雨） when got to school yesterday. While he was doing his homework, the t

2、elephone 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. 難點(diǎn)as when while的辨析as when while都表示主、從句動(dòng)作同時(shí)發(fā)生，三者差異如下：表示“一邊。一邊的意思as 強(qiáng)調(diào)兩個(gè)動(dòng)作同時(shí)進(jìn)行，并表示對比時(shí) ，用于發(fā)生時(shí)間較段時(shí)when： 1、還可以表示從句動(dòng)詞的動(dòng)作

3、在主幾句動(dòng)詞的動(dòng)作之前 或之后發(fā)生。2、whenand then; at that moment (正在那個(gè)時(shí)候)while 、1、用于時(shí)間較長時(shí)2、 強(qiáng)調(diào)兩個(gè)動(dòng)作同時(shí)進(jìn)行，并表示對比時(shí)有時(shí)這三個(gè)連詞可以互換，有時(shí)不可以。It was raining hard when (as) I got there.我到那里時(shí)，正在下大雨。( 動(dòng)作同時(shí)發(fā)生，when可換為as, 但不能換為while，因?yàn)間et是點(diǎn)動(dòng)詞.)When I had read the article, he called me.我看完這篇文章之后，她給我打了電話。( 從句動(dòng)作發(fā)生在主句之前，注意時(shí)態(tài)表達(dá)，只能用when )Whe

4、n I got to the cinema, the film had begun.(當(dāng))我到了電影院時(shí)，電影已經(jīng)開演了。(從句的動(dòng)作發(fā)生在主句之后，只能用when,并要注意時(shí)態(tài))He was about to leave, when the telephone rang.他正要離開，忽然電話響了。( 此時(shí)不能放在句首。主句動(dòng)詞一般表達(dá) “正在” “即將”.while, as不能代替 考點(diǎn))She thought I was talking about her daughter, while, in fact, I was talking about my daughter.他以為我在談她女兒

5、，然而，實(shí)際上在談?wù)撐遗畠骸?表轉(zhuǎn)折，對比，when, as都不能代替它) 考點(diǎn)(2)在時(shí)間狀語從句里，通常不用將來時(shí)態(tài)，用一般現(xiàn)在時(shí)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

6、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。例如：The young man read till the light went out（熄滅）. Lets wait until the rain stops. We wont start until Bob comes. Dont 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(shí)候，而在那個(gè)時(shí)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(shí)候，而講話的人在自己心里認(rèn)為，在那個(gè)時(shí)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fro

7、m morning till night，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?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

8、 (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 sh

9、all not（不得；不應(yīng)該）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. Si

10、nce 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。例如

11、： 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（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

12、。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.（天花板）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 agai

13、n. =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

14、roses. He has so little time that he cant go to the cinema（去看電影） 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（為了，以便）引導(dǎo)。例如： We started early so that we could catch the first trai

15、nHe 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

16、 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

17、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. 總結(jié)：狀語從句分類及常用連詞： 類別 連 詞 時(shí)間狀語從句 when, whenever, while, as, before, after, since, till, once（一旦） 地點(diǎn)狀語從句 where, wherever 原因狀語從句 because, since, as, for, now that（既然，

18、由于）etc. （et cetera，等于and so on）目的狀語從句 n order that(為了，以便), so that, that, etc. 結(jié)果狀語從句 sothat, so that, suchthat, 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 asas, soas, than, etc. 方式狀語從句 as, as if, as though, etc

19、. 賓語從句賓語從句是一種名詞性從句，在句中作及物動(dòng)詞的賓語，或介詞的賓語，或形容詞的賓語。根據(jù)引導(dǎo)賓語從句的不同連詞，賓語從句可分為三類。1. 由that引導(dǎo)的賓語從句。that只有語法作用，沒有實(shí)在的意義，在口語和非正式文體中可以省略。例如：He said （that） he wanted to stay at home.She doesnt know （that）she is seriously ill.I am sure （that） he will succeed.2. 由連接代詞who, whom, whose, what, which和連接副詞when, where, why,

20、how引導(dǎo)的賓語從句。這些連接代詞和連接副詞在賓語從句中充當(dāng)某個(gè)成分。例如：Do you know who（whom）they are waiting for?He asked whose handwriting was the best.Can you tell me where the No.3 bus stop is?I dont know why the train is late.3. 由if或whether引導(dǎo)的賓語從句。If和whether在句中的意思是“是否”。例如：I want to know if（whether）he lives there. He asked me wh

21、ether（if）I could help him.【賓語從句歌訣】賓語從句三姊妹，that，if/whether，wh-/how展風(fēng)采。展風(fēng)采有三關(guān)，引導(dǎo)詞、語序、時(shí)態(tài)在把關(guān)。主從時(shí)態(tài)要一致，陳述語序永不變。陳述請你選that，疑問需用if/whether連。特殊問句作賓從，原來問詞不用換。三關(guān)過后莫得意，人稱、標(biāo)點(diǎn)需注意。留意變臉的if/when，從句的簡化記心間?！靖柙E解碼】一、三姊妹賓語從句根據(jù)引導(dǎo)詞的不同可分為三種類型：1. 由that引導(dǎo)的賓語從句。如 We knew（that）we should learn from each other.2. 由if/whether引導(dǎo)的賓語從

22、句。如 Please tell me if/whether you have been to America.3. 由who，where，how等連接代詞或連接副詞引導(dǎo)的賓語從句。如： Can you tell me how I can get to the nearest post office? 二、三關(guān)1. 引導(dǎo)詞關(guān)如果從句是陳述句，引導(dǎo)詞用that（that在口語或非正式文體中常省略）；如果從句是一般疑問句，引導(dǎo)詞用if/whether；如果從句是特殊疑問句，引導(dǎo)詞用由疑問詞轉(zhuǎn)換而來的疑問代詞/副詞。2. 語序關(guān)陳述句變?yōu)橘e語從句，語序不變，即仍用陳述語序。如： He is an ho

23、nest boy. The teacher said. The teacher said（that）he was an honest boy.一般疑問句和特殊疑問句變?yōu)橘e語從句，語序變?yōu)殛愂稣Z序。如： Does he work hard? I wonder. I wonder if/whether he works hard. When did he leave? I dont know. I dont know when he left.3. 時(shí)態(tài)關(guān)如果主句是現(xiàn)在的時(shí)態(tài)，從句的時(shí)態(tài)可根據(jù)實(shí)際情況而定。如： I have heard（that）he will come back next we

24、ek.如果主句是過去的某種時(shí)態(tài)，那么從句的時(shí)態(tài)一定要用過去的某種時(shí)態(tài)。如： He said（that）there were no classes yesterday.注意：如果賓語從句表述的是客觀真理、自然現(xiàn)象等時(shí)，不管主句是什么時(shí)態(tài)，從句都要用一般現(xiàn)在時(shí)。如：He said that light travels much faster than sound. 三、人稱的變化和標(biāo)點(diǎn)的使用1. 從句的主語如果是第一人稱，變?yōu)橘e語從句則與主句的主語一致；如果是第二人稱，則與主句的賓語一致；如果是第三人稱，不用變化。如：“May I use your knife?” He asked me. He

25、asked me if he might use my knife.“Do you know her telephone number?” He asked me.He asked me if I know her telephone number.2. 賓語從句的標(biāo)點(diǎn)均由主句決定。主句是陳述句，用句號；主句是疑問句，用問號。如：Who will give us a talk? I dont know. I dont know who will give us a talk.Do you know? Where does he live? Do you know where he lives?

26、 四、兩副面孔if和when既能引導(dǎo)時(shí)間狀語從句，又能引導(dǎo)賓語從句。因此，遇到它們就要認(rèn)真分析一下，它們究竟屬于“兩副面孔”的哪一副。如：If it rains tomorrow, I wont come.（時(shí)間狀語從句）I dont know if it will rain tomorrow. （賓語從句） 五、從句的簡化1. 當(dāng)主句謂語動(dòng)詞是find，see，watch，hear等感官動(dòng)詞時(shí)，從句常簡化為“賓語賓補(bǔ)”結(jié)構(gòu)，賓補(bǔ)為不帶to的不定式或V-ing形式。如：She found that the wallet was lying on the ground.She found the

27、 wallet lying on the ground.2. 當(dāng)主句謂語動(dòng)詞是hope，wish，decide，forget，plan，agree等，且主句主語與從句主語相同時(shí)，從句可簡化為不定式結(jié)構(gòu)。如：She agreed that she could help me with my maths. She agreed to help me with my maths.3. 在連接代詞/副詞引導(dǎo)的賓語從句中，當(dāng)從句主語與主句主語或間接賓語一致時(shí)，賓語從句可簡化為“連接代詞/副詞不定式”結(jié)構(gòu)。如：Can you tell me how I can get to the station? Ca

28、n you tell me how to get to the station?【中考范例】1. Miss Green didnt tell us _ in 2002. A. where does she live B.
