高中英语状语从句用法解析
一、 定义: 在句中作状语的从句是状语从句,修饰主句中的动词、形容词或副词等。状语从句由从属连词 引导,从属连词在句中不充当句子成分,只起连接作用,状语从句放在句首时,要用逗号,放 在句尾时不用。 二、 分类 根据意义上的不同, 状语从句可分为: ①时间状语从句②地点状语从句③原因状语从句④目的 状语从句⑤条件状语从句⑥结果状语从句⑦让步状语从

句⑧方式状语从句⑨比较状语从句 三、 时间状语从句 (一)引导 时间状语从句的连词有:as, when(whenever), before, after, as soon as, until(till), since, every time, once. (二) 、 “as” as, when, while 都有“当??的时候”,可以互用 When she was a child. While she was a child. She Lived in Paris. As she was a child. as 有“一边?一边”的意思 He sang as he walked. “when” When the clock struck twelve, all the lights went out. I was sleeping when she came in. 动补 When we arrived at the station, the train had left. “while” 主、从句动作或状态同时发生。用 while 引导的从句用延续性动词,常表示较长的 时间或一个过程。 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. when, while 并列连问。 when 和 while 都可用作并列连问, 连接并列分句。 When 表示“就在?? 的时候”, while 意反而,可是,表示转折。 One evening Beethoven was walking in a street, when he suddenly stopped outside a little house. 并列连词引导并列句,意思是就在那时。
(三)、主句是一般将来时,时间状语从句用一般现在时表将来,主句是过去将来时,从句用

一般过去时表示过去将来时,主句是一般过去时,从句用一般过去时。 1. I' ll call you when I get there. 2. They said they would leave when they got the new. 3. They left as soon as they got the new.

Whenever 无论什么时候,随时 1. Whenever someone throws in some rubbish, the truck produces a piece of music. 每当有人扔进一些垃圾时,它(汽车)就放一段音乐。 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.你随时来看我。

till 和 until(表示“直到??”)句首多用 until 1、在肯定句中表示“直到??为止”,主句谓语动词要用延续性动词。 I was waiting until/till he arrived.

2、在否定句中表示“直到??才”主句谓语动词常用终止性动词,这时 until 和 till 常被 before 替换。 I didn' t leave till/until she came back.

since: 主句用完成时,从句用一般过去时,since 引导的从句间或可用现在完成时。 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 ?? (一段时间)+since+一般过去时态句子。 It is two years since my sister married.

??(一段时间) have/has passed since +一般过去时态句子 Two sisters have/has passed since my sister married.

Since+时间点 1. I have been at home since three o' clock this afternoon. 2. Maria has been in China since two years ago.

*every time, each time, next time Every time you get back at night, you drop your boots on the floor. Every time I catch cold, I have pain in my back. (every time 分写不可以合写) 比较 everyday (adj) 日常的,普通的 every day 是名词短语,每天,天天 Next time I go there, I will visit them. * once 一旦?就 Once you begin, you must go on. 你一开了头,就应该继续下去。

四、 地点状语从句 地点状语从句用 where, wherever 引导

We should go where the people need us.我们应该去人民需要我们的地方。 Where there is a will, there is a way. 有志者,事竟成。

Wherever they went, they received a worm welcome. 无论他们走到哪儿都受到热烈欢迎。 She follows him wherever he goes. 他无论到哪里她总跟着。

五、 原因状语从句 原因状语从句用 because(因为),since(既然), as(由于)引导 1、 字母由多到少,语气由强到弱。

2、 由 why 提问必须用 because 回答。 Since, as 不回答 why 的提问,而且从句一般放在句首,because 一般放在主句之后。

3、 because of +名词 Because of the rain, we didn' t go to the park.

4、 because 和 so 不可连用,只能选其一。 (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,我一定这样做。 Since a lot of people make mistakes in life, Mr Smith wanted to give John a Chance.

5、 for 并列连词,不能放在句首,主要放在两个并列句之间。For 所提供的理由为一个补充 说明,而且前面常有逗号隔开。

The days we short, for it is December now. *改错 Because he is ill is the reason why he can' t come. (Because 改为 that)

六、 目的状语从句 目的状语从句用 so(常用于口语), that, so that, in order that 引导 目的状语从句的谓语常含有 may, might, can, could, should, would 等情态动词。

七、 条件状语从句 条件状语从句由 if, unless, (so) as long as(只需)引导 在条件状语从句中要用一般时表示将来时(与时间状语从句相同)

We will miss the train if you don' t hurry. He said we would miss the train if we didn' t hurry. You will fail the exam unless you study hard. (if you don' t study hard) He won' t come unless he is invited. (if he isn' t invited) Eat less food unless you want to become fatter. (if you don' t want to become better) As long as you are not afraid of difficulties, you are sure to succeed.

As long as you don' t lose heart, you will succeed.

八、 结果状语从句 结果状语从句由 such?that, so?.that, so that, that 引导 1. such? that 的常用句型 such +a/an +形容词+可数名词单数+that such +形容词+可数名词单数+that Such+形容词+可数名词复数(不可数名词)+that

注意 so many (much, few, little) +名词,such a lot of (或 lots of)+名词是惯用法,不 可乱用。 She is such a beautiful girl that we all like her. They were such beautiful flower that we bought home. It was such delicious food that they ate it up.

2. so+形容词或副词+that so+形容词+a/an+可数名词单数+that He is so rich that he can buy lot of things for himself. He works so hard that he did everything well. It was so hot a day that we all went swimming. It was such a good day that we all went swimming.

3.so that, that 都可以引导结果状语从句 He didn' t study hard, (so) that he failed the exam.

4.too?to, enough?to 可以引导结果状语从句与 so?that 替换,so?that 结构可以用

too?to 替换必须具备两个条件,一是主句和结果状语从句的主语必须一致,二是从句中的谓 语部分必须含有 can(could) not. She is young that she can' t go to school. She is too young to go to school. She isn' t old enough to go to school.

九、 让步状语从句 although, though even though = even if, whether?or however = no matter how whatever = no matter what whoever = no matter who whenever = no matter when wherever = no matter where

*although 和 though 都表示“虽然”只是 although 更正式,多用于句首,而 though 用于句 中,二者都可与 yet, still 连用,但不与 but 连用

Although/Though they are poor, they often help others. They are poor, but they often help others. Although he has failed many times, he doesn' t give up trying. Whatever/No matter what you say, I won' t believe you. No matter what you say, I don' t care. No matter who you are, you must obey the rules of our school. However hard he tried, he failed again. No matter what the weather is like, you can always find surfers out riding the waves.

十、 方式状语从句 方式状语从句由 as(如同,按照),as if (though)引导 *as 和 like 都有“像”的意思,as 是连词,后面连接句子,like 是介词后面可加名词、代词 或名词性短语。 I did the work as others did. 相当于 I did like others. You must do as I do.

as if(though)两者意义相同,从句谓语动词常用虚拟语气,但实现可能性较大,则用连接词。 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)
