初中英語狀語從句講解、練習(xí)與答案

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 te

2、lephone 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.(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：I ll ring you up as soon as I get to New York.I will tell him everything when

3、he comes back.He won t 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） .Let s wait until the rain stops.We won t start until Bob come

4、s.Donget 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from morning tillnight ，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?Don t leave the building unless

5、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：I ll helpyou with your English if am free tomorrow.He won t be late unless he is ill.(3) “使句祈 + 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 you ll be=Iflateyou. don t hurry up, you ll be late.Study hard and you will pass the exam. =If you

6、 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 didn t come to school because he was ill.As it is raining, we shall not（不得；不應(yīng)該）go the zoo.1Since you can t answer the question, I ll 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。回答由 why 提出的問題，只

7、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 aren t going there?- Because I don t want to.As he has no car, he can t get there easily.Since we have no money, we can t 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so that, such that, so 引that導(dǎo)。例如：He is so poor th

8、at he can t 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 couldn t see it.(2) so that語 such.that 可以互換。例如：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 couldn t say a word.The hall

9、 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。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 a

10、lmost 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 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 mis

11、s 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 cango to the cinemat （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(jí)+ than 等連詞引導(dǎo)。例如：Tom runs

12、 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：2We 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

13、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.Al

14、though 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, t

15、here 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，由于） etc. （ et cetera，等于 and so on）目的狀語從句in 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
