1、精選優(yōu)質(zhì)文檔-傾情為你奉上狀語(yǔ)從句的概念：狀語(yǔ)從句指句子用作狀語(yǔ)時(shí)，起副詞作用的句子。它可以修飾謂語(yǔ)、非謂語(yǔ)動(dòng)詞、定語(yǔ)、狀語(yǔ)或整個(gè)句子。根據(jù)其作用可分為時(shí)間、地點(diǎn)、原因、條件、目的、結(jié)果、讓步、方式和比較等從句。狀語(yǔ)從句一般由連詞(從屬連詞)引導(dǎo)，也可以由詞組引起。從句位于句首或句中時(shí)通常用逗號(hào)與主句隔開，位于句尾時(shí)可以不用逗號(hào)隔開。比較while/as/when：1、as/when引導(dǎo)短暫性動(dòng)作的動(dòng)詞例句：如：Just as/Just when/When I stopped my car, a man came up to me.2、當(dāng)從句的動(dòng)作發(fā)生于主句動(dòng)作之前，只能用when引導(dǎo)這個(gè)從句

2、，不可用as或while。如：When you have finished your work, you may have a rest.3、從句表示“隨時(shí)間推移”連詞能用as，不用when或while。如：As the day went on, the weather got worse.比較untill/till：兩個(gè)連詞意義相同,肯定形式表示的意思是“做某事直至某時(shí)”，動(dòng)詞必須是延續(xù)性的。否定形式表達(dá)的意思是“直至某時(shí)才做某事”，動(dòng)詞為延續(xù)性或非延續(xù)性都可以。正確使用這兩個(gè)連詞的關(guān)鍵之一就在于判斷句中的動(dòng)詞該用肯定式還是否定式。肯定句例句：I slept until midnight.

3、我一直睡到半夜時(shí)醒了。 Wait till I call you. 等著我叫你。注意：在肯定句中可用before代替：Lets get in the wheat before the sunsets.否定句例句：She didnt arrive until 6oclock.I didnt manage to do it until you had explained how.1、Until可用于句首，而till通常不用于句首。例句：Until you told me, I had heard nothing of what happened.2、Untilwhen疑問(wèn)句中，until要放在句首

4、。例句：Until when are you staying? 你呆到什么時(shí)候？注意：否定句可用另外兩種句式表示。1）Not until在句首，主句用倒裝。例句：Not until the early years of the19th century did man know what heat is.2）It is not untilthat狀語(yǔ)從句的用種類：1、時(shí)間狀語(yǔ)從句：表示時(shí)間的狀語(yǔ)從句可由when, as, while, whenever, after, before, till(until), since, once, as soon as(或the moment), by th

5、e time, no soonerthan, hardly(scarcely) when, everytime等引導(dǎo)。 e.g. When I came into the office, the teachers were having a meeting. He started as soon as he received the news. Once you see him, you will never forget him. No sooner had I gone to bed than I went to sleep. 2、原因狀語(yǔ)從句：原因狀語(yǔ)從句是表示原因或理由的，引導(dǎo)這類從句

6、的最常用的連詞是because, since, as, nowthat（既然）等，for表示因果關(guān)系時(shí)（它引導(dǎo)的不是從句）為并列連詞，語(yǔ)氣不如because強(qiáng)。 e.g. He is disappointed because he didnt get the position. As it is raining, I will not go out. Now that you mention it, I do remember. 3、地點(diǎn)狀語(yǔ)從句： 引導(dǎo)地點(diǎn)狀語(yǔ)從句的連詞是where和wherever等。 e.g. Sit wherever you like. Make a mark wher

7、e you have a question. 4、目的狀語(yǔ)從句： 引導(dǎo)目的狀語(yǔ)從句最常用的詞（組）是so, so that（從句謂語(yǔ)常有情態(tài)動(dòng)詞）, in order that, in case（以防，以免）等。 e.g. Speak clearly, so that they may understand you. She has bought the book in order that she could follow the TV lessons. He left early in case he should miss the train. 5、結(jié)果狀語(yǔ)從句： 結(jié)果狀語(yǔ)從句是表示事態(tài)

8、結(jié)果的從句，通常主句是原因，從句是結(jié)果。由so that（從句謂語(yǔ)一般沒有情態(tài)動(dòng)詞）,sothat, suchthat等引導(dǎo)。 e.g. She was ill, so that she didnt attend the meeting. He was so excited that he could not say a word. She is such a good teacher that everyone admires her. 6、條件狀語(yǔ)從句： 條件狀語(yǔ)從句分真實(shí)性（有可能實(shí)現(xiàn)的事情）與非真實(shí)性（條件與事實(shí)相反或者在說(shuō)話者看來(lái)不大可能實(shí)現(xiàn)的事情）條件句。引導(dǎo)條件狀語(yǔ)從句的詞（組）

9、主要有if, unless, so(as)long as, on condition that, so(as) far as, if only(=if)。注意：條件從句中的if不能用whether替換。 e.g. If he is not in the office, he must be out for lunch. You may borrow the book so long as you keep it clean. So far as I know（據(jù)我所知）, he will be away for three months. You can go swimming on cond

10、ition that(=if) you dont go too far away from the river bank. If he had come a few minutes earlier, he could have seen her. 7、讓步狀語(yǔ)從句： 讓步狀語(yǔ)從句可由although, though, as, even if(though), however, whatever, whetheror, no matter who(when, what,)等引導(dǎo)。注意：as引導(dǎo)的讓步狀語(yǔ)從句一般是倒裝的。 e.g. Though he is a child, he knows a

11、 lot. Child a she is, he knows a lot. Whatever(=No matter what) you say, Ill never change my mind. 8、方式狀語(yǔ)從句： 方式狀語(yǔ)從句常由as, as if(though), the way, rather than等引導(dǎo)。 e.g.You must do the exercise as I show you. He acted as if nothing had happened. 9、比較狀語(yǔ)從句： 比較狀語(yǔ)從句常用than, so(as)as, the morethe more等引導(dǎo)。 e.g

12、. I have made a lot more mistakes than you have. He smokes cigarettes as expensive as he can afford. The busier he is, the happier he feels.使用狀語(yǔ)從句時(shí)要注意的幾個(gè)問(wèn)題：1、在時(shí)間和條件（有時(shí)也在方式、讓步等）從句中，主句是一般將來(lái)時(shí)，從句通常用一般現(xiàn)在時(shí)表示將來(lái)。e.g. Well go outing if it doesnt rain tomorrow. Ill write to you as soon as I get to Shanghai. 2

13、、有些時(shí)間、地點(diǎn)、條件、方式或讓步從句，如果從句的主語(yǔ)與主句主語(yǔ)一致（或雖不一致，是it），從句的謂語(yǔ)又包含動(dòng)詞be，就可省略從句中的“主語(yǔ)+be”部分。e.g. When(hewas) still a boy of ten, he had to work day and night. If(you are) asked you may come in. If(it is) necessary Ill explain to you again. 3、注意區(qū)分不同從句：引導(dǎo)的是什么從句，不僅要根據(jù)連詞，還要根據(jù)句子結(jié)構(gòu)和句意來(lái)判別。以where為例，能引導(dǎo)多種從句。e.g. You are to

14、 find it where you left it.（地點(diǎn)狀語(yǔ)從句） Tell me the address where he lives.（定語(yǔ)從句，句中有先行詞） I dont know where he came from.（賓語(yǔ)從句） Where he has gone is not known yet.（主語(yǔ)從句） This place is where they once hid.（表語(yǔ)從句）注意：表示“一就”的結(jié)構(gòu) hardly/scarcelywhen/before/no soonerthan和as soon as都可以表示“一就”的意思。例句：I had hardly/sc

15、arcely got home when it began to rain. I had no sooner got home than it began to rain. As soon as I got home, it began to rain.注意：如果hardly/scarcely或nosooner置于句首，句子必須用倒裝結(jié)構(gòu)：例句：Hardly/Scarcely had I got home when it began to rain. No sooner had I got home than it began to rain.從屬連詞的概念：連詞用于引導(dǎo)從句以形成句子的一部分

39、r, hence, as well as, both.and, notonly.butalso, either.or, neither.nor, (and)then 等等。并列連詞與并列結(jié)構(gòu)：并列連詞引導(dǎo)兩個(gè)并列的句子。1）and與or：判斷改錯(cuò)：(錯(cuò)) They sat down and talk about something.(錯(cuò)) They started to dance and sang.(錯(cuò)) I saw two men sitting behind and whisper there.(對(duì)) They sat down and talked about something.(對(duì)

40、) They started to dance and sing.(對(duì)) I saw two men sitting behind and whispering there.解析：第一句：and連接兩個(gè)并列的謂語(yǔ)，所以talk應(yīng)改為talked。 第二句：and連接兩個(gè)并列的動(dòng)詞不定式，第二個(gè)不定式往往省略to，因此sang應(yīng)改為sing。 第三句：and連接感觀動(dòng)詞saw后面的用作的賓補(bǔ)的兩個(gè)并列分詞結(jié)構(gòu)，因此whisper應(yīng)改為whispering。注意：and還可以和祈使句或名詞詞組連用表示條件。（or也有此用法）如：Make up your mind, and youll get th

41、e chance.=If you make up your mind, youll get the chance. One more effort, and youll succeed.=If you make one more effort, youll succeed.2）both.and 兩者都如：She plays(both) the piano and the guitar.3）not only.but(also), as well as 不但而且如：She plays not only the piano, but(also) the guitar.注意：not onlybut a

42、lso關(guān)聯(lián)兩個(gè)分句時(shí)，一個(gè)分句因有否定詞not而必須倒裝。如：Not only does he like reading stories, but also he can even write some.4）neither.nor 意思為“既不也不”謂語(yǔ)動(dòng)詞采用就近原則，與nor后的詞保持一致。如：Neither you nor he is to blame.比較so和such ：so與such的用法由不同詞性決定。such是形容詞，修飾名詞或名詞詞組，so是副詞，只能修飾形容詞或副詞。so還可與表示數(shù)量的形容詞many，few，much，little連用，形成固定搭配。構(gòu)成：so+adj. such+a(n)+n. so+adj.+a(n)+n. such+n.(pl.) so+adj.+n.(pl.) such+n.(pl.) so+adj.+n.不可數(shù)such+n.不可數(shù)如：so foolish such a foolso nice a flowe
