英语学习:as引导的五种状语从句

Hard as it was raining, they went on working in the field. 虽然天下大雨,但他们继续在田地里干活。

4. as表示“按照”、“依照”、“像”,引导方式状语从句,从句置于主句之后。例如:

5. as表示“像……一样”,引导比较状语从句,对主句和从句的动作或状态加以比较,说明它们之间有相似之处,在从句中常省略与主句相同的部分。例如:

He doesn't work as hard as I (do). 他不像我工作那样努力。

I hope the necklace was as good as the one you lent me.我希望我挂项链同你借给我的一样好。

初中英语状语从句知识点总结

初中英语状语从句知识点总结(一) 用来修饰主句中的动词,形容词或副词等而充当状语的从句叫做状语从句。状语从句常用从属连词来引导,与主句连接起来。若置于句末,则前面不加逗号。根据意义和作用,状语从句可分为时间原因条件等几种。下面我们就来分析一下这几种状语从句。 1时间状语从句 时间状语从句常用从属连词when,after,until,as soon as,等来引导。 当主句是祈使句或谓语动词是一般将来时态或情态动词时,其时间状语从句中的谓语动词常用一般现在时态表示将来发生的动作或存在的状态。这就是我们常说的“主将从现”。 如:Please call me when you get there.当你到那时,请给我打个电话。 I will write to you as soon as I arrive in Beijing.我一到北京就给你写信。 <温馨提示>since引导时间状语从句表示“自从…以来”,从句中的动词一般表示动作的起点,用过去时;而主句的动作延续的情况则用一般现在时或现在完成时。常用的句型为: It has been/is+一段时间+since+过去时。 如:I has been/is three years since we met last time.自从我们上次见面,已经三年了。 2条件状语从句 引导条件状语从句的连词或词组有:if(如果),unless(除非),as long as(只要)等。如果主句是将来时,条件状语从句也用一般现在时来表示。 如:I will stay at home if it rains tomorrow.如果明天下雨,我就待在家。 You can’t learn English well unless you wo rk hard. 除非你努力学习,否则是学不好英语的。 <温馨提示>由if引导的条件状语从句,若从句表达的是与现在事实相反的事实,则常用虚拟语气,即用过去时态表示(如果涉及到be动词,一律都用were)。此时,主句则用过去将来时。

as引导的时间状语从句

as引导的时间状语从句 as是高中英语中非常重要的一个词汇,它的用法非常的复杂,且在每年的高中英语考试中占有非常重要的位置。其中as引导的时间状语从句尤为复杂,本文以as在引导时间状语从句时的三种不同意义为线索,细致讲述as引导时间状语从句这一语法知识点。 as引导时间状语从句表示"当....时候" as在表示"当....时候"的意义时,与"while"引导时间状语从句有一个共同点,就是此时从句的谓语动词一定要用表示延续性的动词。 例句1:She stayed up late writing her paper while our kids and I were sleeping. 当我和孩子们在睡觉的时候,她在熬夜写论文。 注释:这个句中while引导的时间状语从句的谓语动词是表示延续性的"were sleeping"。例句2:They all finished their homework, as I was playing with my dog. 当我在和我的小狗玩耍的时候,他们都完成了家庭作业。 注释:从句中的谓语动词"was playing"是表示延续性的动词。 as引导时间状语从句表示"一边...一边..." 当as表示"一边...一边..."引导时间状语从句时,主句和从句的动作同时发生,此时从句的谓语动词没有要求。 例句1:As she explained her misfortunes, she wiped tears off her cheeks. 她一边讲述着自己的不幸遭遇,一边擦去脸上的泪水。 例句2:She cried as she walked alone on the dark road. 她一边独自走在黑暗的小路上,一边哭泣。

中考初中英语状语从句分类及例句 考试要求: 状语从句概念: 用一个句子(从句)来作另一个句子(主句)的状语,用作状语的句子就叫作状语从句。作什么样的状语就叫什么类型的状语从句。引导状语从句的连接词是从属连词,状语从句可以在句首,也可以在句尾。 中考主要考查状语从句的类型有: 时间状语从句、地点状语从句、原因状语从句、结果状语从句、目的状语从句、条件状语从句及比较状语从句等。 1. 时间状语从句: 时间状语从句在主句中表示时间,常用连接词有:when(当……时),while(当……时),as(当……时),before(在……之前),after(在……之后),since(自从),not…until(直到……才), as soon as(一……就),once(一旦……就)等。 例如: I didn’t go to bed until I finished my homework. 我直到做完作业才去睡觉。 I can listen to the radio while I work. 我可以边听收音机边工作。 (1) 时间状语从句中,一般要用一般现在时代替一般将来时,一般过去时代替过去将来时。例如: I will telephone you when he comes. 他来时,我会给你打电话。 I’ll stay here until you come back. 我会呆在这里,直到你回来。 (2) when引导时间状语从句,表示主句的动作和从句的动作同时或先后发生,从句的谓语可以是延续性动词,也可以是瞬间动词。

例如: He was working when I went in. 我进去时他正在工作。 When she heard the news, she began to cry. 她听到这个消息,她哭了起来。 (3) while引导的状语从句中常用延续性动词或表示状态的动词,意思是“在……期间”。 while还可以表示两者之间的对比关系。 They rushed in while we were singing. 我们唱歌时,他们冲进来。 I like playing football, while Tom likes listening to music. 我喜欢踢足球,而汤姆喜欢听音乐。 (4) as引导状语从句,强调同时发生,不分先后。可以译成“随着”或“一边……一边”。 例如:John sings as he walks home. 约翰一边往家走一边唱歌。 (5) since引导状语从句,主句常用现在完成时,从句常用一般过去时。 We have been friends since we met in Beijing. 自从我们在北京遇到就一直是朋友。 It has been six years since she left school. 自从她毕业已经有六年了。 (6) until/ till 引导时间状语从句,当主句的谓语动词是瞬间动词时,主句常用否定形式,not… until意思为“直到……才”。 He didn’t go to bed until he finished his homework. 他直到做完作业才睡觉。 2.地点状语从句:

as引导的五种状语从句

as作从属连词用时,可以引导五种状语从句。现归纳如下: 1. as表示“当……的时候”,引导时间状语从句,多强调主句和从句中的动作或状态同时发生,从句可放在主句前,也可放在主句后。例如: As I waited at the stop, I heard a big noise. 当我在车站等车的时候,我听到一个很大的声响。 She rose up as he entered. 当他进来时,她站了起来。 2. as表示“因为”、“由于”,引导原因状语从句,其语气不如because强,通常为附加说明的理由,且是已知晓的原因,主句与从句没有逻辑上的因果关系。例如: As she was not well, I went there alone. 因为她身体不好,所以我独自到那里去了。 As he is a tailor, he knows what to do with this material. 由于他是个裁缝,他知道怎样利用这块布料。 3. as表示“虽然……但是……”,引导让步状语从句,从句通常用倒装语序,把从句的表语、状语或动词原形放在as前面,可以用though替代。例如: Child as he is, he knows a lot. 虽然他是个孩子,但他知道的东西很多。 Hard as it was raining, they went on working in the field. 虽然天下大雨,但他们继续在田地里干活。 4. as表示“按照”、“依照”、“像”,引导方式状语从句,从句置于主句之后。例如: You should do as the teacher tells you.你应当依照老师所说的去做。 The absence of air also explains why the stars do not seem to twinkle in space as they do from the earth. 空气的不存在,也说明了为什么在空中星星看来并不闪烁,而不像从地球上看的那样。 5. as表示“像……一样”,引导比较状语从句,对主句和从句的动作或状态加以比较,说明它们之间有相似之处,在从句中常省略与主句相同的部分。例如: He doesn't work as hard as I (do). 他不像我工作那样努力。 I hope the necklace was as good as the one you lent me.我希望我挂项链同你借给我的一样好。
