中考狀語從句專題講解加配套練習

1、第四講狀語從句知識要點列舉要點一、狀語從句概述狀語主要是用來修飾動詞和形容詞的，以表明動作發(fā)生或狀態(tài)存在的時間、地點、原因、目 的、結果等。狀語從句即指在主從復合句中用作狀語的從句。狀語從句主要用來修飾主句或 主句的謂語。要點二、狀語從句的分類按照其意義不同一般可分為九大類，分別是：1、時間狀語從句2、原因狀語從句3、目的狀語從句4、結果狀語從句5、條件狀語從句6、讓步狀語從句7、地點狀語從句8、比較狀語從句9、方式狀語從句初中階段主要掌握前而1到6種狀語從句。要點三、狀語從句的分類講解1、時間狀語從句用表示時間的連詞連接一個句子作狀語，這樣的主從復合句就是時間狀語從句。常用引導詞:when,

2、 as, while, as soon as, before, after, since, till, until如： I didnt realize how special my mother was until I became an adult.While John was watching TV, his wife was cooking.知識拓展（一）由when, while, as引導的時間狀語從句的區(qū)別用法A when引導的從句的謂語動詞可以是延續(xù)性的動詞，又可以是瞬時動詞。并且when有時 表示“就在那時”。如：When she came in, I stopped eatin

3、g.她進來時,我在吃飯。（瞬時動詞）When I lived in the countryside, I used to carry some water for him.當我的住在農村時，我常常為他擔水。（延續(xù)性的動詞）（3）We were about to leave when he came in.我們就要離開，就在那時他進來了。（就在那時） While引導的從句的謂語動作必須是延續(xù)性的，并強調主句和從句的動作同時發(fā)生（或者 相對應）。并且while有時還可以表示對比。如： While my wife was reading the newspaper, I was watching T

4、V.（was reading是延續(xù)性的動詞，并且was reading和was watching同時發(fā)生）1 like playing football while you like playing basketball我喜歡踢足球,而你喜歡打籃球。（對比） As表示“一邊.一邊，as引導的動作是延續(xù)性的動作，一般用于主句和從句動 作同時發(fā)生；as也可以強調“一先一后。如：We always sing as we walk.我們總是邊走邊唱。（as表示“一邊一邊“）（2）As we was going out, it began to snow.當我們出門時,開始卜雪 了。（as強調句中兩個動

5、作緊接著先后發(fā)生，而不強調開始下雪的特定時間）（二）由before和after引導的時間狀語從句的區(qū)別用法（ before引導的從句不再用否定式的謂語，并且當before引導的從句位于主句之后，有時 譯成“就，才還要注意主句和從句之間的時間關系。當主句用將來時，從句總是用現(xiàn)在時; 如果before引導的從句謂語用的是過去時，則主句動詞多用過去完成時，這樣以便體現(xiàn)動 作發(fā)生的先后。如：It will be four days before they come back.他們要過四天才能回來。Einstein almost knocked me down before he saw me.愛因斯坦

6、幾乎把我撞倒才看到我，My father had left for Canada just before the letter arrived.我父親恰好在信到之前去加拿大了。They had not been married four months before they were divorced.他們結婚還不到四個月就離始了。A after表示主句動作發(fā)生在從句動作之后。主句和從句的動作的時間關系正好與before引 導的從句相反。如： After you think it over, please let me know what you decide.你仔細考慮過以后，告訴我你是怎樣

7、決定的。After we had finished the work, we went home.完成工作之后，我們回家了。(從句用過去完成時，主句用一般過去時)(H) till或until引導的時間狀語從句的區(qū)別till和until 一般情況下兩者可以互換，但是在強調句型中多用untiL但要注意的是：如果主句中的謂語動詞是瞬時動詞時，必須用否定形式；如果主句中的謂語動詞是延續(xù)性動詞時，用肯定或否定形式都可以，但 表達的意思不同。till不可以用在句首，而until可以放在句首。如：I didn*t go to bed until (till) my father came back.直到我父

8、親回來我才上床睡覺。It was not until the meeting was over that he began to teach me English.直到散會之后他才開始教我英語。I worked until he came back我工作到他回來為 ihoI didnt work until he came back.他回來我這才開始工作。Please wait until I arrived.在我到達之前請等我(四)since引導的時間狀語從句的用法since引導的從句的謂語動詞可以是延續(xù)性的動詞，又可以是瞬時動詞。一般情況下，從句 謂語動詞用一般過去時，而主句的謂語動詞用現(xiàn)

9、在完成時。但在Itis +時間+ since從句的 句型中，主句多用一般現(xiàn)在時。如：I have been in Beijing since you left.自從你離開以來，我一直在北京了。Where have you been since I last saw you自上次我和你見面以后，你到哪里去了It is four years since my sister lived in Beijing.我妹妹不在北京住有四年了。It is five months since our boss was in Beijing.我們老板離開北京有五個月了。（五）在時間狀語從句中，當主句是一般將來時或

10、祈使句表示將來的意義時，時間狀語從 句用一般現(xiàn)在時。如：111 let him know as soon as she comes.她一來，我就會讓你知道。Jane didn/t go to work until she finished her homework.簡直到完成作業(yè)才睡覺。2、原因狀語從句用表示原因的連詞連接一個句子作狀語，這樣的主從復合句就是原因狀語從句。原因狀語從句通常由because, since, as,for引導。如：He didnt come to school because he was ill.As it is raining, we shall not go

11、the zoo.Since you cant answer the question, I,ll ask someone else.知識拓展because表示直接原因，語氣最強。Because引導的原因狀語從句多放在主句之后?；卮?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引導的原因狀語從句多放 在句首。for有時也可引出表示原因的分句，但它只能位于后而，對前一分句加以解釋或推斷。如： 一Why arent you going there?Because I dont want to.As he has no car, he

12、cant get there easily.Since we have no money, we cant buy it.3、目的狀語從句用表示目的的連詞連接一個句子作狀語，這樣的主從復合句就是目的狀語從句。引導目的狀語從句的從屬連詞主要有in order that, so that, in case, for fear等如：I hired a boat so that I could go fishing.我租了一條船去約魚.Take your raincoat in case it rains （should rain）.帶上雨衣以防卜雨。He studied hard in order

13、that he could pass the exam他努力學習是為了 能通過考試.知識拓展so that既可引導目的狀語從句，又可引導結果狀語從句。區(qū)別這兩種從句的辦法有兩個： 目的狀語從句里往往帶有情態(tài)動詞can, could, may, might等。從意思上看，目的狀語從句往往表示的目的很明確。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.（結果狀語從句）4.結果狀語從句引導結果狀語從句的從屬連詞主要有so that, so.that, s

14、uch.that等。如：He was so angry that he couldnt speak.他氣得話都說不出來。He shut the window with such force that the glass broke.他關窗子用力太大,玻璃都震破了。【注工so.that 和 such.that 可以互換。在由so.that引導的結果狀語從句中，so是副詞，與形容詞連用。其結構是:.SO+形容 詞（副詞）+ that +從句。如：The hall is so big that it can hold 2,000 people.Mother lives so far away tha

15、t we hardly ever see her.在由such.that引導的結果狀語從句中，such是形容詞，它修飾的可以是單數(shù)或復數(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 而需加不定冠詞a或an“如：It was such a hot day that nobody wanted to do anything.He made such rapid progress that he did very well in the mid-term.有時上述兩種結構是可以互換的.如：It was such a wonderful film that a

16、ll of us wanted to see it again.=The film was so wonderful that all of us wanted to see it again.如果名詞前由many, much/ittle, few等詞修飾時，只能用so,不用such。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.sothat句型的否定形式可用簡單句tooto或not.e

17、nough to代替。如：He is so young that he cant go to school.他太小了，不能上學。=He is too young to go to school.=He is not old enough to go to school.5、條件狀語從句引導條件狀語從句的從屬連詞主要有if, unless, as so long as等。 I如： Dont come unless I telephone.除非我打電話，否則你別來。If you watch carefully you will see how to do it.如果你仔細看，你會看出該怎樣做。在條

18、件狀語從句里，謂語動詞通常用現(xiàn)在時態(tài)表示將來的動作或狀態(tài)（主將從現(xiàn)）。如：111 help you with your English if am free tomorrow.He wont be late unless he is ill.祈使句+and（or）+陳述句（一般將來時）”在意思上相當于一個帶有條件狀語從句的 復合句。如：Hurry up, or youll be late.=lf you don/t hurry up, you/ll be late.Study hard and you will pass the exam.=lf you study hard, you wil

19、l pass the exam.6 .讓步狀語從句引導讓步狀語從句的從屬連詞主要有although, though, even though, even if （即使）， 如:The speech is good, though it could be better.這次演講不錯,雖然還可以再好一點。 He went out even though it was raining.盡管下著雨，他還是出去了。連詞while有時也可表示“盡管“、雖然，引導讓步狀語從句。如： While we dont agree with each other, we continue to be friends.

20、盡管我們意見不同，我們還是朋友。whatever, whoever, however, whenever, wherever 等弓I 導讓步狀語從句。如：Dont lose heart whatever you do.不管你做什么，都不要灰心。Whoever you are, you can*t pass this way.不管你是誰，你都不能從這里通過。【注意】：表示“雖然的though, although不可與but連用,但可與yet, still連用。as也可引導讓步狀語從句，但要將名詞、形容詞或副詞等提到as前，若提前的是單數(shù)可 數(shù)名詞，要省略a或an.如：Teacher as he

21、is, he cant know everything.雖然是老師，他也不可能什么都懂.例題精析will stay healthy you do more exercise, such as running and walking.A. if B. how C. before D. where答案：Ac思路分析：該題考查的是引導狀語從句的從屬連詞的選擇。從意思上看，從句應是一個條件 狀語從句，在這四個選項中只有if能引導條件狀語從句，所以選A。2. -Shall we go on working?-Yes,I prefer to have a rest.A. whenB. ifC. becau

41、e watching TVA. whereB. when C. whileD. but()25.I admit that there are problems, I dont agree that they cannot be solved.A. WhileB. IfC. AsD. Unless答案與思路分析：1. A.因為gave后而已經(jīng)有表示物的直接賓語了，排除代詞A、C、和D。however意為無 論如何“；whenever意為每當.”，根據(jù)句意，只有選C,意義才通。2. A.因為前面已經(jīng)連詞though 了，所以不再需要連詞了 . Hard-working though he was=

42、Although he was hard-working。3. B.因為as引導讓步狀語從句，要求將從句的表語或狀語等放到句首。而although, while 表示讓步時，都用正常語序；另外，though引導的讓步狀語從句，其表語或狀語等可提前 也可不提前。4. C.因為 immediately, instantly, directly 和 the moment, the instant, the minute 等都可以 用作連詞，引導時間狀語從句，相當于assoonas。5. C.因為表示“正要做某事時，突然又發(fā)生另一件事”的句型是：was/were just about to do st

43、h. whendid或 was /were just on the point of doing sth. when.did.6. C.因為notuntil，直到才”，再接before語意上不通,要用after。7. C.因為no matter后一定要接疑問詞或whether8. C.引導狀語從句時no matter how=however,其后接形容詞或副詞,只有C正確。9. C. unless除非、如果不。句意是：大多數(shù)動物與其它不同種類的動物都沒有什么聯(lián)系, 除非是把它們獵為食物。10. A.句意是：雖然他認為他在幫我們做工，但事實上他是在擋事。11. B.表示主、從句的謂語動詞同時變化

44、的隨著只能用as。12. B.因為keep the portrait （把照片放在）后而一定是指所放的“地方”了，所以用where （在的地方）引導一個地點狀語從句。13. C.因為非謂語動詞的邏輯主語就是句子的主語,mistakes不能check,排除A和D： 若用B,則前后是兩個句子，又無連詞，排除B。14. A.只有先A,前后意義才通：even if即使、縱然：so that為了、以便：as if.好象： ever since從（那時）到現(xiàn)在。15. D.因為the moment可作連詞，與as soon as相當。16. D. until （直到.J與肯定句連用，引出的時間是主句謂語動

45、詞結束的時間。even though 即使：in case以防萬一：whenever每當、無論何時。17. C.因為 now that =since既然18. A.因為with pride （驕傲地）是固定短語：where （在的地方）引導一個地點狀語從 句，19. D.由where引導一個地點狀語從句，表示坐（sat）的地方：后而是帶有連詞的現(xiàn)在 分詞作時間狀話，when waking=when he woke。20. C.因為It will be +時間段+ before.是固定句式，意為“過之后才句意是：要過 五年之后，我們才會再次見面。21. B.因為whatever = no mat

46、ter what引導一個讓步狀語從句,并作difficulty的定語。句 意是：你無論遇到什么困難，也決不要灰心喪氣。）22. C.句意是：如果不允許我們喝啤酒，我們就不能喝。23. C.因為無先行詞，不是定語從句，而是由where引導的一個地點狀語從句。句意是: 在它們過去居住的地方，你仍然可以找到鳥的骨頭。24. B.題中when=since既然。句意是：既然他們把所有的空閑時間都用來看電視了，他 們還能學到什么呢25. A.因為while可以表示讓步，與although相當，意為雖然能力提升A組閱讀下面短文，掌握大意，然后從A、B、C、D四個選項中選出最佳選項。My son Joey w
