江蘇省無錫市高三英語總復(fù)習(xí)教案(藝考生)：專題九狀語從句教師版

1、【知識(shí)要點(diǎn)】 定義：用來充當(dāng)狀語的句子稱為狀語從句。功能：它主要用于修飾句子中的謂語動(dòng)詞、形容詞或副詞等，有時(shí)修飾整個(gè)句子。位置：狀語從句的位置較活：可以放在主句之前，用逗號(hào)與主句隔開；也可以放在主句之后，一般不用逗號(hào)。由于它是從各個(gè)方面來修飾、說明謂語動(dòng)詞發(fā)生時(shí)的各種情況，所以常見的狀語從句有九種之多。各種不同的狀語從句所使用的關(guān)系詞也各不相同。 一、時(shí)間狀語從句引導(dǎo)時(shí)間狀語從句的從屬連詞有很多，現(xiàn)將分類用法如下：1.從屬連詞when，while與as連詞用法謂語動(dòng)詞意義例句when從句的動(dòng)作和主句的動(dòng)作可以同時(shí)發(fā)生，也可以先后發(fā)生?？梢灾笗r(shí)間的某個(gè)點(diǎn)，也指一段時(shí)間。延續(xù)性動(dòng)詞非延續(xù)性動(dòng)詞當(dāng)

2、時(shí)候When they heard the news，they all jumped with joy.I owed Jack $ 100 when I was in London.as從句的動(dòng)作與主句的動(dòng)作同時(shí)發(fā)生?？梢灾笗r(shí)間的某個(gè)點(diǎn)，也指一段時(shí)間。延續(xù)性動(dòng)詞非延續(xù)性動(dòng)詞隨著一邊；一邊當(dāng)時(shí)候The students sang as they walked.As he stood up，he dropped the glass，breaking it into pieces.while從句的動(dòng)作與主句的動(dòng)作同時(shí)發(fā)生，強(qiáng)調(diào)一段時(shí)間。從句中常用過去進(jìn)行時(shí)態(tài)或一般過去時(shí)態(tài)。延續(xù)性動(dòng)詞當(dāng)時(shí)候在期間Wh

3、ile I was reading，he came in.I made some foreign friends while I was in London.注： 1)when還可作并列連詞，其意義為“那時(shí)，這時(shí)”，相當(dāng)于and at this/that time。常用于下列句式： sb. was doing sth. when.某人正在干某事就在這時(shí)sb. was about to/ going to do sth. when.某人正打算干某事就在這時(shí)sb. has just done some sth. when.某人剛干了某事就在這時(shí)2)when還表示原因“既然”。如：It was fo

4、olish of you to take a taxi when you could easily walk here in five minutes.既然你可以步行五分鐘就能到這兒，坐出租車來真是愚蠢。3)while作為并列連詞，意為“而，卻”，表示對(duì)比。He likes pop music，while I am fond of folk music.他喜歡流行音樂，而我卻喜歡民間音樂。4)如果主句表示的是短暫動(dòng)作，而從句用延續(xù)性動(dòng)詞的進(jìn)行時(shí)態(tài)表示在一段時(shí)間內(nèi)正在進(jìn)行的動(dòng)作時(shí)，when，while與as可互換使用。如：When/While/As I was walking down the

5、street，I came across an old friend of mine.我在街道上走的時(shí)候，見到了我的一個(gè)老朋友。2.從屬連詞：as soon as，immediately，directly，the moment，the minute，no sooner.than.,hardly/scarcely. when.，once這些從屬連詞引導(dǎo)的從句都表示從句的動(dòng)作一發(fā)生，主句的動(dòng)作隨即就發(fā)生，意為“一就”。從句中用一般時(shí)態(tài)代替將來時(shí)態(tài)。如：Once you remember it，youll never forget it.一旦你記住它，就永遠(yuǎn)不會(huì)忘記。The moment I hea

6、rd the voice，I knew father was coming.我一聽到聲音，就知道是父親來了。No sooner had we arrived at the station than the train left.我們一到達(dá)車站，車就開了。注：no sooner.than.; hardly/scarcely.when.這一結(jié)構(gòu)的時(shí)態(tài)搭配：no sooner與hardly/scarcely引導(dǎo)的主句謂語動(dòng)詞應(yīng)用過去完成時(shí)，而than與when的從句中謂語應(yīng)用一般過去時(shí)。此外，當(dāng)把no sooner和hardly/scarcely提到句首時(shí)，應(yīng)用倒裝語序。我一到家，天就開始下雨了。I

7、 had hardly got home when it began to rain.Hardly had I got home when it began to rain.3.till，until (not.until/till.直到才)連詞用法動(dòng)詞意義例句till/until主語和從句都用肯定式主句的動(dòng)詞為連續(xù)性動(dòng)詞一直到為止Ill stay here till/until the rain stops.not.till/until主句用否定形式，從句用肯定形式主句的動(dòng)詞為非連續(xù)性動(dòng)詞直到才He didnt go home till/until he finished his homewo

8、rk.注：1) till不可以置于句首，而until可以置于句首。如：Until you told me I had no idea of it.直到你告訴我，我對(duì)此事才有所了解。2)如果將“not until.”結(jié)構(gòu)放在句首，那么主句要寫成倒裝句。如：Not until we pointed out their fault to them did they realize it.直到我們向他們指出了他們的錯(cuò)誤，他們才意識(shí)到。4.every time，each time，next time等名詞短語用來引導(dǎo)時(shí)間狀語從句，表示“每當(dāng)，每次，下次”。如：Every/Each time I was

9、in trouble，he would come to help me out.每次我遇到麻煩，他總會(huì)來幫我。Next time you come，do remember to bring your son here.下次你來的時(shí)候，一定要記得把你兒子帶來。5.從屬連詞：before(在之前)，after(在之后)，since(自從以來)。如：Please remember to turn off all the lights before you leave the classroom.離開教室前，請(qǐng)記得把所有的燈都關(guān)上。注：1)上述三個(gè)連詞，既是從屬連詞，也是介詞。2)若表達(dá)“還未就”“不

10、到就”“才”“趁，還沒來得及”時(shí)，需用連詞before。如：We had sailed four days and four nights before we saw land.我們航行了四天四夜才看到陸地。We hadnt run a mile before he felt tired.我們跑了還不到一英里他就累了。Please write it down before you forget it.趁你現(xiàn)在沒忘把它記下來。二、地點(diǎn)狀語從句1.常用的引導(dǎo)詞有where（在地方）,wherever（無論在什么地方）等。指具體地點(diǎn)時(shí)，從句可用于主句之前或之后，表示抽象條件時(shí)，從句須放在主句之前。如

11、：The university graduates are determined to go wherever they are needed most.那些大學(xué)畢業(yè)生們決心去最需要他們的地方。They are planting trees where there is plenty of water and sunlight.他們?cè)陉柟庥晁浞值牡胤街矘?。Where there is a will, there is a way.有志者事竟成。2.注意區(qū)分where引導(dǎo)的定語從句與狀語從句。你最好在有問題的地方作個(gè)標(biāo)記。Youd better make a mark where you ha

12、ve any questions.(狀語從句)Youd better make a mark at the place where you have any questions.(定語從句)三、條件狀語從句1.常用的引導(dǎo)詞有if（如果，假如）,unless（除非，要不就不）,as long as（只要）,so long as（只要）,provided (that）（只要），suppose/supposing（假設(shè)），on condition (that）（如果）等。如：I may not come to see you recently unless I can complete the pr

13、oject ahead of time.除非我能提前完成那個(gè)項(xiàng)目，否則我最近不會(huì)來看你了。We can surely attain our goal as long as we are united as one.只要我們團(tuán)結(jié)一致，我們肯定能實(shí)現(xiàn)我們的目標(biāo)。What shall we do if we can not get the necessary data？如果我們弄不到必要的數(shù)據(jù)，我們?cè)趺崔k？They promised to let us have a meeting in their office on condition(that）we could keep it clean.如果

14、我們能保持清潔，他們答應(yīng)讓我們?cè)谒麄兊霓k公室里開會(huì)。2.要點(diǎn)提示：1)在表示條件的狀語從句中，既可以用直陳語氣作“真實(shí)條件句”，也可以用虛擬語氣作“非真實(shí)條件句”。至于把句子作成哪一種條件句，要依照“有關(guān)語法規(guī)則”和“表達(dá)意思的需要”而定。 2)用unless引導(dǎo)條件狀語從句時(shí)，要注意這個(gè)連詞自身在意義上是否定的：unless=if.not.。因此，我們?cè)谶壿嬌弦⒁猓河⑽木渥拥挠梅ê椭形木渥拥淖g文。特別是當(dāng)主句是否定句時(shí)，邏輯上的意思就成了“否定之否定而表示肯定”的情況了。如：I will not go to their party unless I am invited.這個(gè)句子的實(shí)際意義

15、等于：I will not go to their party if I am not invited.這就是說，“我不去參加聚會(huì)”的條件是“我沒有受到邀請(qǐng)”。“不去”與“沒有受到邀請(qǐng)”就構(gòu)成了“否定之否定而表示肯定”的情況了。）假如他們不邀請(qǐng)我，我不會(huì)去參加他們的聚會(huì)。He will finish the work in time unless something unexpected happens.這個(gè)句子的實(shí)際意義等于：He will finish the work in time if something unexpected does not happen.假如沒有什么意外的事情發(fā)

16、生，他會(huì)按時(shí)完成他的工作的。3)suppose/supposing這兩個(gè)詞所表達(dá)的意義和句法功能是一樣的。它們與其他的引導(dǎo)狀語從句的從屬連詞一樣，引導(dǎo)一個(gè)含狀語從句的主從復(fù)合句。而它們的特別之處在于：有時(shí)由它們所引出的條件狀語從句常與主句分開而獨(dú)立成句，但其意義和作用還是條件狀語從句。這種情況多數(shù)出現(xiàn)在科技文章及某些論文里。如：Suppose no more rain fell into the Atlantic Ocean and no more water was brought to it by rivers.It would take the ocean about 4000 year

17、s to dry up.假如不再有雨水注入大西洋，不再有河水流入大西洋的話；大約需要四千年的時(shí)間大西洋才會(huì)枯竭。Suppose your statement is right.How are you going to prove it? 假定為你的觀點(diǎn)是正確的，你打算如何證明這一點(diǎn)呢？Suppose this poor girl is yours. Wed like to know how much you know about her.假設(shè)這個(gè)可憐的女孩就是你的；我們想了解你知道多少關(guān)于她的情況。四、原因狀語從句1.常用的引導(dǎo)詞有because因?yàn)?as由于,since既然，由于,now t

18、hat既然，由于,not that.but that不是因?yàn)槎且驗(yàn)椋瑂eeing that，considering that等。如：He cant deliver his lectures today because he has got a bad cold.他今天不能去講課了，因?yàn)樗剂酥馗忻?。I may not be able to attend your wedding party not because Im not willing to but because Ive been caught by something recently.我或許無法參加你的婚禮了，不是我不想去而是近

19、來有些事情纏著我無法脫身。2.要點(diǎn)提示：1) 從屬連詞用法區(qū)別區(qū)別項(xiàng)目位置內(nèi)涵語氣能否回答why能否被強(qiáng)調(diào)because因?yàn)橹骶淝盎蚝笾苯右蚬P(guān)系強(qiáng)能能as由于主句前或后since/now that 既然主句前雙方都知道的原因弱不能不能主句前if/when主句前或后2)關(guān)于since和now that這兩個(gè)詞在表示原因的時(shí)候是近義詞，都表示“既然”。但其不同之處在于：now that只能以“新發(fā)生的情況”作為某事發(fā)生的原因；而since在表示“既然”時(shí),就沒有這種限制。如：Now that the rain is going to stop, wed better get ready for

20、the afternoons match. 既然雨要停了，我們最好為下午的比賽作好準(zhǔn)備。（此句中，now that引出的從句顯然是表示“新出現(xiàn)的情況”，在句子中作“主句動(dòng)作發(fā)生的原因”。也就是說，只有在這種情況下才可以用now that引導(dǎo)從句，表示“既然”。）Since youre so interested in English, why not have a try in the English Speech Contest?既然你對(duì)英語這么有興趣，為什么不試一試參加英語演講比賽？3）其他表示原因的方式除了狀語從句外，一些介詞短語同樣可以表示原因，這樣的短語有because of; th

21、anks to; due to; owing to等。五、讓步狀語從句引導(dǎo)讓步狀語從句的從屬連詞有though（雖然）,although（雖然），even if（即使）,even though（即使）,as(盡管)，while(雖然),whether.or.(無論還是),no matter+疑問詞（無論）。1.though或although引導(dǎo)讓狀語從句。although與though兩者意思相同，一般可互換，都可以與yet，still或nevertheless連用，但不能和but連用。如：He is unhappy though/although he has a lot of money.

22、雖然他有許多錢，但他并不幸福。Although/Though it was raining hard，yet they went on playing football. 盡管雨下的很大，但他們?nèi)栽诶^續(xù)踢足球。注：though還可用作副詞，意為“可是，然而”，置于句末。如：He said he would come；he didnt though.他說他會(huì)來，可是他沒有來。2.當(dāng)as作“盡管，雖然”的意思講引導(dǎo)讓步狀語從句時(shí)，從句往往放在主句的前面，而且用作讓步的部分（表語、狀語或動(dòng)詞原形）總是提前到句首。若表語是名詞，前置時(shí)要省略冠詞。如：Child as he is，he knows a

23、lot.盡管他是孩子，他卻懂得很多。Old as he is, he is still energetic.盡管他老了，卻依然精力充沛。（表語作為讓步的內(nèi)容，因此提前了。）Try as he might , he couldnt solve the problem.盡管他很努力了，但還是無法解決這個(gè)問題。(謂語提前了）Much as you suspected him, you couldnt provide powerful evidence.雖然你非常懷疑他，但是你卻無法提供有力的證據(jù)。（狀語作為讓步的內(nèi)容，因此提前了。）3.whether.or（不管） 疑問詞+ ever與no matt

24、er+疑問詞（不管，無論）。however（不管怎樣）,whatever（無論什么）,whoever（無論誰）。no matter when(how, what, who, where, which）無論何時(shí)（怎樣，什么，誰，何地，哪個(gè)）等。如：Air exists everywhere although we cant see it.盡管我們看不見空氣，但它卻無處不存在。No matter where you go on the earth, you will feel the gravity.無論你走到地球的什么地方，你都會(huì)感覺到地引力。Well start our meeting on

25、time whether he comes or not.無論他來不來，我們將準(zhǔn)時(shí)開會(huì)。Even if we are approaching the end of the experiment, we still have no time to lose.即使我們即將完成試驗(yàn)，我們依然要分秒必爭(zhēng)。注：whoever，whatever，whomever，whichever還可以引導(dǎo)名詞性從句。如：You can take whatever you like.你可以拿任何你所喜歡的東西。六、方式狀語從句常用的引導(dǎo)詞有as（如同，按照）,as if（似乎，仿佛）,as though（似乎，仿佛）等。

26、如：He speaks English almost as a native speaker does.他的英文幾乎說得如講英語母語的人一樣。He speaks English as if he were a native speaker.他講英文的樣子似乎像說英語母語的人。She looked unwell as though she got a bad cold.她看上去身體不適好像患有重感冒。In this reading room you can read anything as everyone does here.在這間閱覽室里，你可以像這兒的每個(gè)人一樣想看什么就看什么。要點(diǎn)提示：

27、as if或as though引導(dǎo)的方式狀語從句中，如果表示真實(shí)情況應(yīng)該用直陳語氣；如果表示非真實(shí)情況則應(yīng)該用虛擬語氣。關(guān)于這一點(diǎn)也取決于說話人的態(tài)度、看法。如：It gets darker and darker in the sky as if its going to rain.天越來越暗了似乎要下雨了。（表示真實(shí)情況，是直陳語氣）She speaks as if she knew everything in the world.她說話的樣子仿佛似她懂得天下事。（表示非真實(shí)情況，是虛擬語氣）七、目的狀語從句常用的引導(dǎo)詞有so that（以便，為了）,in order that（為了）,le

28、st（以免，以防）,in case（以免，以防）,for fear（以免，以防）等。如：We should do our utmost in order that we may be able to over fulfill the task.為了超額完成任務(wù)，我們應(yīng)該全力以赴。Youd better leave your phone number, so that I can call you before I come next time.你最好將電話號(hào)碼留給我，以便我下次來之前可以先給你打個(gè)電話。Batteries must be kept in dry places for fear

29、that electricity leaks away.電池應(yīng)該放在干燥的地方，以免漏電。要點(diǎn)提示：在目的狀語從句中，我們可以將這些引導(dǎo)目的狀語從句的連詞so that, in order that，lest, in case, for fear分作為兩大部分：表示肯定so that, in order that是“為了使發(fā)生(目的是，為的是)”。表示否定lest, in case, for fear是“為了使不發(fā)生（以免，以防）”。另外，在表示否定的目的狀語從句中，謂語動(dòng)詞往往用“should+動(dòng)詞原形”或“動(dòng)詞原形”兩種虛擬句式。如：He took his umbrella with hi

30、m lest it should rain.他帶了雨傘，以防下雨。Ill keep a seat for you in case you should change your mind.我給你留個(gè)座，沒準(zhǔn)你會(huì)改變主意。八、結(jié)果狀語從句1.常用的引導(dǎo)詞有that（結(jié)果，以至），so that（結(jié)果，以至），so.that（如此以至）,such.that（如此以至）等。如：The temperature is increased so that the volume of gas becomes greater.溫度升高了氣體的體積就增大了。The mountain is so high that

31、 she cant climb it up to the top.那座山太高了，她無法登上山頂。It is such a lovely day that everybody feels happy and gay.天氣這么好，人人都感到高興、快樂。注：1)so.that和such.that都是引導(dǎo)結(jié)果狀語從句的從屬連詞，它們都表示“如此以至”，但其要求的句型結(jié)構(gòu)不一樣。如：He ran so fast that his brother couldnt catch up with him.他跑得太快了，他弟弟趕不上他。He is such a naughty boy that he become

32、s unwelcome in his neighborhood.他是那么個(gè)調(diào)皮的孩子，以至在鄰里中不受歡迎。She looks so lovely that everybody cant help taking a look at her when passing her by.她生得太可愛了，從她身邊經(jīng)過的人都忍不住要看她一眼。2)當(dāng)so或such置于句首時(shí)，主句要用倒裝語序。如：So clever was he that he was able to work out all the difficult problems. 他是如此聰明以至于他能解出所有的難題。2.除結(jié)果狀語從句外，too

33、.to.(太而不能)，enough to.(能夠)，so.as to.(那么以至于)等不定式結(jié)構(gòu)同樣可以表示結(jié)果。如：他起床晚了，結(jié)果誤了車。He didnt get up early enough to catch the bus.=He got up too late to catch the bus.=He got up so late as to miss the bus.九、比較狀語從句常用的引導(dǎo)詞有than（比）,as.as（如一樣）,“the +比較級(jí).,the+比較級(jí).”（越越）等。如：He is taller than his brother.他比他弟弟個(gè)高一些。The mo

34、re they discover about the brain, the more questions they cant answer in that area.他們?cè)蕉嗟匕l(fā)現(xiàn)有關(guān)人腦的情況，他們就有越多的問題無法回答。要點(diǎn)提示：有關(guān)比較狀語的問題請(qǐng)看前面“形容詞與副詞的比較級(jí)和最高級(jí)”一章。這里只提醒一個(gè)關(guān)于比較狀語從句的問題。那就是：than和as.as中的第二個(gè)as都是連詞，后面若是人稱代詞，常用主格形式。如：Her mother is not as tall as she（is）.她媽媽沒有她個(gè)高。I dont think that he is taller than I.我并不認(rèn)

35、為他比我個(gè)高。十、狀語從句中的省略1.若從句中的主語與主句的主語一致，同時(shí)從句中又含有系動(dòng)詞be，則通常省去從句的主語和系動(dòng)詞be而保留其余部分。如：While (she was) very young，she began to study English.她很小的時(shí)候就開始學(xué)英語。2.若從句主語是it，動(dòng)詞是系動(dòng)詞be,則通常省去主語it及系動(dòng)詞be而保留其余部分。如：Everything went on better than (it had been) expected.一切進(jìn)展得比預(yù)料的要好。3.若從句中部分內(nèi)容與主句中的部分內(nèi)容相同，可將從句中的此部分內(nèi)容省略。如：She has n

36、o money. If (she has) any，she will give us. 她沒錢，如果有的話，她會(huì)給我們的?！究键c(diǎn)詮釋】考點(diǎn)1 狀語從句的時(shí)態(tài)高考主要考查時(shí)間、條件、讓步狀語從句用一般現(xiàn)在時(shí)表將來及一般過去時(shí)代替過去將來時(shí)的用法。如：He said he would go to Japan for holiday when he finished writing the book他說他寫完這本書后會(huì)去日本度假。Even if it snows tomorrow，the performance wont be called off即使明天下雪，演出也不會(huì)取消?？键c(diǎn)二 狀語從句的結(jié)構(gòu)

37、高考主要考查結(jié)構(gòu)較為復(fù)雜、特殊的狀語從句，如no matter+疑問詞；whatever，however，as引導(dǎo)的讓步狀語從句；“the+比較級(jí)，the+比較級(jí)”中的比較狀語從句等。如：The harder you work，the better your studies will be你學(xué)習(xí)越努力，功課就越好。No matter what serious difficulties he met with，he could always overcome them不管碰到多么可怕的困難，他總能克服?？键c(diǎn)3 狀語從句的省略在時(shí)間、原因、條件、方式、讓步等狀語從句中，常常省略相同的主語或作主語的

38、代詞it以及be動(dòng)詞，保留現(xiàn)在分詞、過去分詞、介詞短語、不定式等成分。如果從句中有“it is+形容詞”，也可以省略it is。如：Once printed，this dictionary will be very popular一旦出版，這本詞典會(huì)非常暢銷。(once后省去了it is)Do not leave the building until instructed to do SO接到指示后才可離開這幢房子。(until后省去了you are)考點(diǎn)4 從屬連詞的選擇和辨析高考重點(diǎn)考查引導(dǎo)狀語從句的從屬連詞，如引導(dǎo)時(shí)間狀語從句的immediately，the moment，every t

39、ime，once；引導(dǎo)條件狀語從句的as long as；引導(dǎo)原因狀語從句的now that，since；引導(dǎo)讓步狀語從句的even if，even though；引導(dǎo)目的狀語從句的in case，in order that等。如：We hadnt met for 20 years，but I recognized him the moment I saw him我們已經(jīng)有20年沒見面了，可是我一見到他就認(rèn)出他來了。(時(shí)間狀語從句)We should bring a knife in case that there ale any dangerous animals there我們應(yīng)當(dāng)帶把刀，

40、以防那兒有什么危險(xiǎn)動(dòng)物。(目的狀語從句)考點(diǎn)5 where引導(dǎo)地點(diǎn)狀語從句要注意where引導(dǎo)的地點(diǎn)狀語從句和where引導(dǎo)的定語從句、表語從句以及賓語從句的區(qū)別。如：The flower grows best where it often rains這種花在經(jīng)常下雨的地方長(zhǎng)得最好。(地點(diǎn)狀語從句)The flower grows best in the place where it often rains這種花在經(jīng)常下雨的地方長(zhǎng)得最好。(定語從句)典題鏈接【示例1】It is almost five years _ we saw each other last time.A. beforeB

41、. sinceC. afterD. when解析:此題考查時(shí)間狀語從句的用法。這是一個(gè)典型的句型結(jié)構(gòu)：It is/has been+段時(shí)間+since+句子(一般過去時(shí))。句子意思是：自從我們上次見面幾乎有五年了。答案：B【示例2】There were dirty marks on her trousers _ she had wiped her hands.A. whereB. whichC. whenD. that解析:根據(jù)句子結(jié)構(gòu)，由于從句結(jié)構(gòu)完整，可排除B、D兩項(xiàng)；前面的先行詞是on her trousers表地點(diǎn)，where在此引導(dǎo)狀語從句，where相當(dāng)于in the places

42、 where，本句意思是：在她褲子上擦手的地方有臟跡。答案：A特別提示：學(xué)會(huì)將where引導(dǎo)的狀語從句轉(zhuǎn)換成介詞短語(地點(diǎn))+where引導(dǎo)的定語從句是逐步掌握這種用法的好辦法?！臼纠?】We were told we should follow the main road _ we reached the central railway station.A. wheneverB. untilC. whileD. wherever解析:根據(jù)兩句子的關(guān)系不存在讓步，從而可排除選項(xiàng)A、D；再根據(jù)句意，表示until前面的動(dòng)作或者狀態(tài)一直持續(xù)到until后面的地點(diǎn)或時(shí)間。答案選B。本句意為：有人告訴

43、我們應(yīng)沿大路走，一直走到中心車站。答案：B【示例4】You can eat food free in my restaurant _ you like.

A. howeverB. no matterC. althoughD. whatever解析:根據(jù)句子結(jié)構(gòu)，排除選項(xiàng)B、C，因B項(xiàng)后面需連接副詞when，how，where或連接代詞who，what，而C項(xiàng)后面的句子不能倒裝；當(dāng)名詞前有much，many，little，few等修飾時(shí)，

45、前面不能用whatever，故選A。答案：A【示例7】Id like to arrive 20 minutes early _ I can have time for a cup of tea.

46、is medicine on human patients.A. sinceB. afterC. beforeD. when解析:根據(jù)句子的意思，科學(xué)家對(duì)藥品先要進(jìn)行反復(fù)試驗(yàn)后才能用于病人身上，因此答案選C。本題考查了before的固定句型，即It was/will be+時(shí)間段+before+主+謂(did/do)。答案：C特別提示：要選對(duì)連詞，一定要清楚主從句之間的語意和邏輯關(guān)系。思維升級(jí)怎樣做好狀語從句試題呢？首先我們應(yīng)該系統(tǒng)地掌握狀語從句的基本知識(shí)，把握每個(gè)連詞的具體用法；其次我們要正確區(qū)分容易混淆的連詞，像as, when, while, since, even if ,as if等

47、；再者，要善于理清句子的邏輯關(guān)系，要具備分析長(zhǎng)難句的能力。要特別注意as引導(dǎo)讓步狀語從句、時(shí)間狀語從句、方式狀語從句和原因狀語從句的不同用法。例如：As time went on, Einsteins theory proved to be correct.(時(shí)間)As(=Since) the weather is fine, lets go.（原因）Do as you like.（方式）Child as/though he is, he knows a lot.（讓步）思維鏈接【示例】_ I explained on the phone, your request will be consi

48、dered at the next meeting.A. WhenB. AfterC. AsD. Since解析:此題考查as引導(dǎo)定語從句和狀語從句的區(qū)別。此題中as引導(dǎo)的是非限制性定語從句，as指代后面整句話的內(nèi)容，意為“正如”。句子意思是：正如我在電話里所解釋的，你的要求會(huì)在下次會(huì)議上考慮。A和B兩項(xiàng)都指時(shí)間，D項(xiàng)表示“既然”，指原因，都引導(dǎo)狀語從句。答案：C特別提示：since既可以引導(dǎo)時(shí)間狀語從句，表示“自從開始”，也可以引導(dǎo)原因狀語從句，表示“因?yàn)?、既然”。Its/It has been 10 years since he enjoyed a good dinner.Since yo

50、2. “Im going to the post office.” “_ youre there, can you get me some stamps?”A. AsB. WhileC. BecauseD. If【陷阱】容易誤選A。【分析】最佳答案選 B。盡管 as 和 while 均可用作從屬連詞引導(dǎo)時(shí)間狀語從句，表示“當(dāng)?shù)臅r(shí)候”，但兩者有一個(gè)重要區(qū)別，就是這樣用的 as 從句的謂語不能是狀態(tài)動(dòng)詞。當(dāng)然，如果 as 不是表示“當(dāng)?shù)臅r(shí)候”，其謂語是完全可以用狀態(tài)動(dòng)詞的。如：I went to bed early, as I was exhausted. 我很累了，所以很早就上床睡了。(此句中的

51、 as 表示原因，意為“因?yàn)椤薄ⅰ坝捎凇?請(qǐng)做以下兩題，答案均選 while，不選as：(1) _ you are at home alone, please dont leave the door open. A. WhileB. AsC. BeforeD.

52、e. A. thatB. whenC. whichD. where【陷阱】幾個(gè)干擾項(xiàng)均有可能誤選。【分析】最佳答案選 D。where 在此引導(dǎo)地點(diǎn)狀語從句，其意為“(在)的地方”。請(qǐng)做以下類似試題(答案均選 where)：(1) The famous scientist grew up _ he was born and in 1930 he came to Shanghai.A. whenB. wheneverC. whereD. wherever(2) She found her calculator _ she lost it. A. whereB. whileC. in whichD.

The visitor asked to have his picture taken _ stood the famous tower.A. thatB. at whichC. whenD. where【陷阱】幾個(gè)干擾項(xiàng)均有可能誤選?！痉治觥孔罴汛鸢高x D。此題與上面一題有些相似，但又有所不同：相似的是，where 均表示“在的地方”，均用以引導(dǎo)地點(diǎn)狀語從句；不同的是，此題還涉及倒裝，即此句的主語是 the famous tower，謂語是 stood，正常詞序?yàn)?where the famous tower stood，使用倒裝是為了保持句子平衡，避免頭重腳輕。5. They kept trying _ they must have known it was hopeless.A. ifB. becauseC. whenD. where【陷阱】幾個(gè)干擾項(xiàng)均有可能誤選。【分析】最佳答案選 C。when 在此的意思不是“當(dāng)?shù)臅r(shí)候”，而是“盡管”、“雖然”的意思。又如：He walks when he m
