第三篇：狀語(yǔ)從句語(yǔ)法講解

高中英語(yǔ)狀語(yǔ)從句

一、定義：

在句中作狀語(yǔ)的從句是狀語(yǔ)從句,修飾主句中的動(dòng)詞、形容詞或副詞等.狀語(yǔ)從句由從屬連詞引導(dǎo),從屬連詞在句中不充當(dāng)句子成分,只起連接作用,狀語(yǔ)從句放在句首時(shí),要用逗號(hào),放在句尾時(shí)不用.二、分類

根據(jù)意義上的不同,狀語(yǔ)從句可分為：①時(shí)間狀語(yǔ)從句 ②地點(diǎn)狀語(yǔ)從句 ③原因狀語(yǔ)從句④目的狀語(yǔ)從句 ⑤條件狀語(yǔ)從句 ⑥結(jié)果狀語(yǔ)從句⑦讓步狀語(yǔ)從句 ⑧方式狀語(yǔ)從句 ⑨比較狀語(yǔ)從句

三、時(shí)間狀語(yǔ)從句主句是一般將來(lái)時(shí),時(shí)間狀語(yǔ)從句用一般現(xiàn)在時(shí)表將來(lái)；主句是過(guò)去將來(lái)時(shí),從句用一般過(guò)去時(shí)表示過(guò)去將來(lái)時(shí)；主句是一般過(guò)去時(shí),從句用一般過(guò)去時(shí).記憶：“主將從現(xiàn)”

（一）引導(dǎo)時(shí)間狀語(yǔ)從句的連詞有：As, when(whenever), before, after, as soon as, until(till), since, every time, once.（二）、具體應(yīng)用1）“while” 主、從句動(dòng)作或狀態(tài)同時(shí)發(fā)生.用while引導(dǎo)的從句用延續(xù)性動(dòng)詞,常表示較長(zhǎng)的時(shí)間或一個(gè)過(guò)程.記憶：While 后用進(jìn)行時(shí).While we were having supper, all the lights went out.Please keep quiet while others are studying.While I was writing letters last night, he was watching TV.2）When表示“就在??的時(shí)候”, while意為反而,可是,表示轉(zhuǎn)折.One evening Beethoven was walking in a street, when he suddenly stopped outside a little house.3）Whenever 無(wú)論什么時(shí)候,隨時(shí)

1.Whenever someone throws in some rubbish, the truck produces a piece of music.每當(dāng)有人扔進(jìn)一些垃圾時(shí),它（汽車）就放一段音樂(lè).2.Whenever we’re in trouble, they will help us.3.I go to the theatre, whenever I am free.4.Come and see me whenever you want to.你隨時(shí)來(lái)看我.4）till和until(表示“直到??”)句首多用until

1、在肯定句中表示“直到??為止”,主句謂語(yǔ)動(dòng)詞要用延續(xù)性動(dòng)詞.I was waiting until/till he arrived.2、在否定句中表示“直到??才”主句謂語(yǔ)動(dòng)詞常用終止性動(dòng)詞,這時(shí)until和till常被before替換.I didn' t leave till/until she came back.5）since: 主句用完成時(shí),從句用一般過(guò)去時(shí),since引導(dǎo)的從句間或可用現(xiàn)在完成時(shí).It is two years since I have studied English.1.We have known each other since we were children.2.We have been friends(ever since)since we met at school.3.It is ??(一段時(shí)間)+since+一般過(guò)去時(shí)態(tài)句子.It is two years since my sister married.??(一段時(shí)間)have/has passed since +一般過(guò)去時(shí)態(tài)句子 Two sisters have/has passed since my sister married.Since+時(shí)間點(diǎn)

原因狀語(yǔ)從句用because(因?yàn)?,since(既然), as(由于)引導(dǎo)

1、字母由多到少,語(yǔ)氣由強(qiáng)到弱.2、由why提問(wèn)必須用because回答.Since, as不回答why的提問(wèn),而且從句一般放在句首,because一般放在主句之后.3、before of +名詞

Because of the rain, we didn' t go to the park.4、because 和so不可連用,只能選其一.（另有although, but）Why didn' t he come to school? Because he was ill.Since I must die, I must.既然我一定要死,我一定這樣做.Since a lot of people make mistakes in life, Mr Smith wanted to give John a Chance.5、for并列連詞,不能放在句首,主要放在兩個(gè)并列句之間.For所提供的理由為一個(gè)補(bǔ)充說(shuō)明,而且前面常有逗號(hào)隔開.The days we short, for it is December now.六、目的狀語(yǔ)從句 目的狀語(yǔ)從句用so(常用于口語(yǔ)), that, so that, in order that引導(dǎo)

目的狀語(yǔ)從句的謂語(yǔ)常含有may, might, can, could, should, would等情態(tài)動(dòng)詞.1.We'll sit never to the front so we can hear well.2.He studied hard so that he might succeed.3.I'll speak slowly so that you can take notes.4.They hurried to the station in order that they could catch the train.5.I took a taxi so that I could get there earlier.6.I’m going to the lecture early so that I may get a good seat.七、條件狀語(yǔ)從句

在條件狀語(yǔ)從句中要用一般時(shí)表示將來(lái)時(shí)（與時(shí)間狀語(yǔ)從句相同）

結(jié)果狀語(yǔ)從句由such?that, so?.that, so that, that 引導(dǎo) 1.Such? that 的常用句型

*as和like都有“像”的意思,as是連詞,后面連接句子,like是介詞后面可加名詞、代詞或名詞性短語(yǔ).I did the work as others did.相當(dāng)于 I did like others.You must do as I do.as if(though)兩者意義相同,從句謂語(yǔ)動(dòng)詞常用虛擬語(yǔ)氣,但實(shí)現(xiàn)可能性較大,則用連接詞.It seems as if/though it’s going to rain.They are talking as if/though they were old friends.She treats me as if I were her brother.When you are in home,do as the Romans do.例 You must do ______ I told you.A.after B.before C.where D.as(D)The students must do ______ the teacher told them.A.as B.before C.after D.if(A)

第五篇：狀語(yǔ)從句

Clauses of Condition, Concession and Contrast(條件、讓步和對(duì)比從句)條件從句

由 if, unless, as(so)long as, provided / providing(that), suppose / supposing(that), in case等引導(dǎo)，如：

If he comes I'll tell you.You would have succeeded if you had tried harder.You will fail unless you work hard.(=You will fail if you don't work hard.)

Supposing / Suppose it rains, shall we have the match as scheduled?

In case you need anything else, please let me know.讓步從句

由 although, though, even though, even if, whether...or, while, as, wh-words + ever(= no matter + wh-words)等從屬連詞引導(dǎo)，如：

He is quite modest though he is the best student in the class.The needle has the same mass whether it is hot or cold.Whichever(No matter which)plan you adopt, you will meet with difficulties.使用上述讓步從句的某些從屬連詞時(shí)注意以下幾點(diǎn)：

a.although(though)不可與連詞 but 連用；

b.as 引導(dǎo)的從句意義和 though 相似，但表示的語(yǔ)氣較強(qiáng)，并須將強(qiáng)調(diào)的詞放在句首（但不用 although），如：

Simple as(though)the question may seem, it is not at all common in nature.c.however / no matter how 引導(dǎo)的從句中，however / no matter how 后須緊跟形容詞或副詞，如：

However / No matter how hard I tried, I couldn't remember all the questions.對(duì)比從句

表示兩個(gè)人或兩件事之間的對(duì)比，常用 while 或 whereas 引導(dǎo)，如：

He is idle, while his brother is diligent.Some people like fat meat, whereas others hate it.Clauses of Cause, Result and Purpose(原因、結(jié)果和目的從句)原因從句

主要由下列從屬連詞引導(dǎo)：

1． Because, as, since。其中 because 語(yǔ)氣最強(qiáng)，表示直接、主要原因，通常引導(dǎo)的從句放在句尾，特別是回答 why 提出的問(wèn)題只能用 because;as 和 since 表示明顯的、已知的原因，since 比 as 正式，如：

They had to move because their building was to be pulled down.As Mary was the eldest, she looked after the others.Since they live near the sea, they often go sailing.2． now that, seeing(that), considering(that), in that。這些連詞與 as, since 意思相近，通常用于書面語(yǔ)，并且它們兼有其它意義。now that 有“時(shí)間”含義，表示”既然”，說(shuō)明一種新

情況；seeing(that)和 considering(that)有“條件”含義；in that 有”某一方面”含義，如：

Now that you are well again you can travel.Seeing(that)they are just beginners, they are doing quite a good job.I was lucky in that I was able to find a good baby-sitter（保姆）.結(jié)果從句

常用 so that, so...that, such...that, that 等連詞引導(dǎo)，如：

I was caught in a shower, so that all my clothes got wet.I was so tired that I could hardly keep my eyes open.He was such a good runner that I couldn't catch him.目的從句

常用 so that, in order(that), lest, for fear that 等連詞引導(dǎo)，如：

I took a taxi so that I could be in time for the meeting.Come closer in order that you may see the blackboard better.so that 既可引導(dǎo)結(jié)果從句也可引導(dǎo)目的從句，但結(jié)果從句表示事實(shí)，通常不含情態(tài)動(dòng)詞；目的從句表示希望或想要實(shí)現(xiàn)的事實(shí)，通常含有情態(tài)動(dòng)詞，如：

He got up early so that he caught the train.（結(jié)果）

He got up early so that he could(might)catch the train.（目的）

Lest 和 for fear(that)含有否定意義，并且從句中動(dòng)詞須用 “動(dòng)詞原形”或 ”should + V.” 的虛擬語(yǔ)氣，如：

He ran away lest he(should)be caught.(= He ran away in order that he would not be caught.)

I checked all the results time and again for fear that there should be any mistakes.(= I checked all the results time and again so that there wouldn't be any mistakes.)

Clauses of Manner and Comparison(方式和比較從句)方式從句

主要由 just as, as, as if, as though 等連詞引導(dǎo)，如：

He doesn't speak the way as other people do.Our bodies are made up of millions of very small cells, just as a building is made of many stones or bricks.He speaks French as if(as though)he were a Frenchman.由 as if 或 as though 引導(dǎo)的從句通常用虛擬語(yǔ)氣，但如果主句謂語(yǔ)是感官動(dòng)詞，并且所述情況實(shí)現(xiàn)可能性大，也可用陳述語(yǔ)氣，如：

It looks as if the coming autumn harvest will be even better than the last one.比較從句

主要由 as...as, not so(as)...as, than 等連詞引導(dǎo)，如：

This table is as wide as that one.Mary can not run so(as)fast as Tom.Silver conducts electricity better than other metals.Clauses of Proportion and Other Types(比例從句和其它從句)比例從句

由關(guān)聯(lián)詞 the...the...連接形容詞或副詞比較級(jí)構(gòu)成，如：

The more she thought about it, the more she liked it.其它從句

如 as...so 和 what...that 引導(dǎo)的類比從句；so(as)far as 引導(dǎo)的范圍從句；except that 引導(dǎo)的例外從句；rather / sooner than 和 would / had rather than 引導(dǎo)的擇比從句等，如：

As the desert is like a sea, so is the camel like a ship.（沙漠似海，駱駝似舟。）

What blood vessel is to a man's body, that railway is to transportation.（鐵路對(duì)于運(yùn)輸，好比血管對(duì)于人的身體。）

As(So)far as I know, he is an honest man.（據(jù)我所知，他是一個(gè)誠(chéng)實(shí)的人。）

I would do it with pleasure, except that I am too busy.（要不是我太忙了，我會(huì)很高興去做的。）

Rather than get money in such a dishonest way, he would beg in the streets.（他寧可沿街乞討，也不愿意用欺騙手段騙取錢。）

He would rather have the small one than the large one.（他寧可要那個(gè)小的，而不愿要那個(gè)大的。）
