初中狀語從句講解及習(xí)題附答案

1、（一）狀語從句概述定義狀語從句用作狀語，是起副詞作用的句子。位置狀語從句可以放在主句之前，也可以放在主句之后，時間、條件、原因和讓步狀語從句放在句首時需要用逗號和主句隔開。分類根據(jù)其作用可以分為時間、地點、原因、條件、目的、讓步、方式和比較等狀語從句。作用它可以修飾謂語、非謂語動詞、定語、狀語和整個句子。（二）狀語從句詳解1. 時間狀語從句引導(dǎo)詞用法示例when意為“當(dāng)?shù)臅r候”。When引導(dǎo)從句的謂語動詞可以是延續(xù)性動詞，也可以是瞬間動詞。并且when有時表示“就在那時”A liar is not believed when he speaks the truth.說謊者講真話時也沒有人相信。

2、When he arrives, Ill call you.When you laugh and smile, your body relaxes. while意為“在的時候，在的同時”。While引導(dǎo)從句的謂語動詞必須是延續(xù)性的，發(fā)生時間較長，并強調(diào)主句和從句的動作同時發(fā)生（或者相對應(yīng)）。While有時還可以表示對比。While I was standing at the window, I saw several boys running along the street. While John was watching TV, his wife was cooking. as意為“一邊一

3、邊”。As引導(dǎo)的動作是延續(xù)性的，發(fā)生時間較短，一般用于主句和從句動作同時發(fā)生；as也可以強調(diào)一前一后。The writer was angry as he was travelling on a train to London because someone had invaded his “space”.He smiled as he stood up. after意為“在之后”。表示主句動作發(fā)生在從句動作之后。主句與從句的動作時間關(guān)系與before引導(dǎo)的從句相反。With many hungry visitors waiting, dont stay too long at your ta

4、ble after you have finished.If an early exit is necessary, you can leave after a scene is over. before意為“在之前”。引導(dǎo)的從句不用否定形式的謂語，并且當(dāng)before引導(dǎo)的從句位于主句之后，有時譯成“就，才”。當(dāng)主句用將來時，從句總是用現(xiàn)在時；如果before引導(dǎo)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)動作的先后。You cant watch TV before you finish your homework.Before it ended, the theatre w

5、as almost empty. My father had left for Canada just before the letter arrived.till意為“直到”。一般情況下可以和until互換。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，用肯定和否定形式都可以，但表達的意思不同。She didnt even know that it was an earthquake till she saw a shaking ( moving from side to side) light.The fireman worked very hard

6、 till the fire was out.until意為“直到”。在強調(diào)句型中多用until。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，用肯定和否定形式都可以，但表達的意思不同。Im waiting for my sister. I wont go to see my uncle until she comes.Wait until I finish what I am doing.since意為“自從，從以來”。引導(dǎo)從句的謂語動詞可以是延續(xù)性的動詞，也可以是瞬時動詞。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)在完成時。但在It

7、is +時間+since從句的句型中，主句多用一般現(xiàn)在時。I have been studying hard since I entered the high school.It is four years since my sister lived in Beijing.It is five years months since our boss was not in Beijing.as soon as意為“一就”。引導(dǎo)時間狀語從句時，如果主句用了將來時，從句一般使用現(xiàn)在時。Tom will call me as soon as he gets home.I will call you a

8、s soon as I arrive.2.地點狀語從句引導(dǎo)詞用法示例where意為“哪里”?！皐here引導(dǎo)的地點狀語從句，（there+）主句”“哪里哪里就”。主句在從句后面時，there可用可不用；主句在從句的前面時，一般都不用there.Where there is a will, there is a way. They were good persons. Where they went, there they were warmly welcomed.You should have put the book where you found it. wherever意為“無論何地”。

9、anywhere/wherever引導(dǎo)地點狀語從句+主句。anywhere本身是個副詞，但是?？梢砸龑?dǎo)從句，相當(dāng)于連詞，意思相當(dāng)于wherever, anywhere引導(dǎo)的從句可位于主句之前，也可以位于主句之后。而wherever本身就是個連詞，表示“在何處，無論何處”。Wherever the sea is, you will find seaman.Ill go anywhere you go.3.條件狀語從句引導(dǎo)詞用法示例if連詞，意為“假如，如果”。當(dāng)主句是將來時的時候，從句要用一般現(xiàn)在時。Dont talk loudly at the meeting. If you do, you

10、will have to leave.Well go for a picnic if it doesnt rain this weekend.unless連詞，意為“除非（=if not）。當(dāng)主句是將來時的時候，從句要用一般現(xiàn)在時。Dont discuss the problems with your partner unless you are asked to do so. I wont go there unless you come with me.4.原因狀語從句引導(dǎo)詞用法示例as意為“因為”。引導(dǎo)原因狀語從句時表示附帶。說明“雙方已知的原因”，語氣比since弱，較為正式，位置較為

11、靈活（常放于主句之前）。As the weather is cold, I stay at home.As it is raining, youd better take a taxi.As you are tired, youd better rest. since意為“因為”。引導(dǎo)的原因狀語從句一般放于主句之前表示已知的、顯然的理由（通常被翻譯成“既然”），較為正式，語氣比because弱。Since the earth looks like a ball, the sun can shine on only half of it at a time. Since the race is

12、in April, I had to run throughout the winter, and in Boston, winters are cold.Since everybody is here. Let's begin our meeting.because意為“因為”。引導(dǎo)的原因狀語從句一般放于主句之后，表述直接原因，語氣較強，最適合why引導(dǎo)的疑問句。Because引導(dǎo)的原因狀語從句有時可以與because of短語互換。The woman prefers winter because she can skate.Id like to collect stamps bec

13、ause they are interesting.Im very tired these days because of studying physics.He cant come because he is ill. = He cant come because of his illness.for意為“因為”。引導(dǎo)的原因狀語從句并不說明主句行為發(fā)生的直接原因，只提供一些輔助性的補充說明，for引導(dǎo)的原因狀語從句只能放于主句之后，并且必須用逗號將其與主句隔開。He must be ill, for he is absent today.He could not have seen me,

14、for I was not there. 5.目的狀語從句引導(dǎo)詞用法示例so that意為“以至，以便”。目的狀語的謂語常含有may, might, can, could, should, would等情態(tài)動詞。Try to speak loud enough so that people can hear you clearly.Mr. Green speaks very loudly so that all the people can hear him clearly. in order that意為“為了”，相當(dāng)于so that. in order to后面可以跟動詞原形構(gòu)成目的狀語，

15、不是目的狀語從句。We shall let you know the details soon in order that you can/may make a arrangements.6.結(jié)果狀語從句引導(dǎo)詞用法示例sothat意為“如此以至于”。so+ adj./adv.原級+that, so是副詞，只能修飾形容詞和副詞。so還可與表示數(shù)量的形容詞many, few, much, little(這四個形容詞表示多或少時)連用,形成固定搭配。so+ many 或few+復(fù)數(shù)可數(shù)名詞+that; so+ much或little+不可數(shù)名詞+that.This year it has raine

16、d so heavily in South China that lots of problems are caused.The ice on the lake was so thin that people couldnt skate on it. Too often, we spend so much time thinking about the future that we fail to enjoy the present.There are so few notebooks that I cant give you any.such.that意為“如此以至于”。有三種結(jié)構(gòu)：such

17、+a(an)+adj.+單數(shù)不可數(shù)名詞+that; such(+adj.)+不可數(shù)名詞+that; such( + adj.) +復(fù)數(shù)可數(shù)名詞+that, such是形容詞，修飾名詞或名詞詞組。有時可與sothat句型轉(zhuǎn)換。Its such a wonderful song that we all like it.Simon is such dishonest person that no one believes him.The boy is so young that he cant go to school.= He is such a young boy that he cant go

18、 to school.7.讓步狀語從句引導(dǎo)詞用法示例though意為“雖然”。不能和but連用。但是可以同yet(still)連用，構(gòu)成thoughyet(still). though較普遍，常用于非正式的口語和書面語中。even能和though組合表示強調(diào)，在這里even though=even if(no matter if; though即使也)。though可以獨立用作副詞，常放在句末，意為all the same(還是；仍然)或however(可是；然而)。So it has lived up to now though it isn't strong at all.Thou

19、gh they are twin brothers, they dont look like each other.Even if/ Even though we could afford it, we would afford it, we wouldnt go abroad for our vacation. although意為“雖然”。不能和but連用。但是可以同yet(still)連用，構(gòu)成althoughyet(still). although 較為正式，語氣比though重，常用以強調(diào)讓步概念。 even不能和although組合。Although he died several

20、 years ago, I can still remember the days we spent together and what he has taught me about love.Although we had little food with us, we decided to spend the night in the car.8. 比較狀語從句引導(dǎo)詞用法示例asas.意為“和一樣”。表示同級的比較。使用時要注意第一個as為副詞，第二個as為連詞。其基本結(jié)構(gòu)為：as+adj./adv.原級+as。若有修飾成分，如twice, three times, half, a qua

21、rter等，則須置于第一個as之前。She is very good at painting. She can paint as well as here teacher.I ran out as quickly as possible. not as / soas意為“和不一樣，不如”。也表示同級比較。She is not so (as ) outgoing as her sister. This dictionary is not as/so useful as you think. 9.方式狀語從句引導(dǎo)詞用法示例as/(just)as.so意為“猶如，就像”。引導(dǎo)的方式狀語從句通常位于主

22、句后，但在(just)as.so結(jié)構(gòu)中位于句首，這時as從句帶有比喻的含義，意為“正如，就像”，多用于正式文體。When in Rome, do as the Romans do.As water is to fish, so air is to man. as if/ as though意為“就像，好像”。兩者的意義和用法相同，引出的狀語從句謂語多用虛擬語氣，表示與事實相反，有時也用陳述語氣，表示所說情況是事實或?qū)崿F(xiàn)的可能性較大。常譯作“仿佛似的，好像似的”。If would never forget here smile, or the way her eyes shone as if w
