按照其意义,状语从句可分为时间状语从句、地点状语从句、原因状语从句、目的状语从句、结果状语从句、条件状语从句、让步状语从句等。
状语从句是高中英语学习中的一个语法重点,也是历年高考重点考查的内容之一。
学习状语从句主要应注意引导状语从句的从属连词的用法与区别,以及从属连词在一定的语言环境中的意义与用法。
二、时间状语从句1.引导时间状语从句的从属连词很多,常见的有before, after, when, while, as,since, till, until, as soon as 等。
2。
表示“当…时候”的while, when, as 的用法区别是:while从句中的谓语动词必须是延续性动词;表示带有规律性的“每当”或当主、从句谓语动词的动作发生有先后时,只能用when;当表示“一边…一边…”或“随着"时,只能用as。
状语从句在句中作状语,修饰主句中的动词,形容词,副词等。
状语从句放在主句之前,常用逗号分开;放在主句之后,一般不用逗号。
状语从句按其意义和作用可分为时间、条件、原因、让步、目的、结果、方式、比较、地点等九种。
状语从句定义及分类状语从句就是用不同的连接词将几个分句连接起来,以表达分句之间特定的逻辑关系。
(一)时间状语从句1、时间状语从句常用连词有when, as, while, before, after, since, till, until, as soon as, hardly...when, scarcely…when, no sooner ... than, the moment, the instant等。
2、时间/条件状语从句一般不用将来时,因此,主句若为将来时,时间状语从句要用一般现在时。
eg. I'll go on with the work when I come back tomorrow.3、连词when, while和as都表示“当…的时候”,when 后接时间点或时间段,表“当…时候”;还可表示“这时,忽然”(用在句型中)及“既然”while 后只可接时间段,表“当…时候”;还可表示“而,然而”as 引导持续性动作,强调主句和从句的动作同时发生,译为“一边…一边”eg. While/when I was reading, he came in.When he came in, we were having a meetingAs he walked along the street, he sang happily.4、till或until表示“一直到…时”,主句和从句都用肯定式,主句用延续性动词;表示“直到…才…”时,主句用否定式,用终止性动词,从句用肯定式。
till不能置于句首。
e.g He worked till/ until it was dark.He did not get up till/ until his mother came in.注意till / until在表达方式和意义上的特殊性:until是till的强调形式,但是它们表达的意义是相同的,都表示“直到某时”。
条件状语从句和结果状语从句【知识梳理1】条件状语从句(1) if引导的条件状语从句If引导条件状语从句。
翻译成“如果”If I were a bird ,I would fly 如果我是一只鸟,我就会飞。
(2) unless引导的条件状语从句unless引导的是否定条件状语从句,在意义上相当于if...not,而且语气较强,一般不用于虚拟语气。
如:You’ll be late unless you hurry. 你会迟到的,如果不赶快的话。
(3) only if引导的条件状语从句only if在引导条件状语从句时意为“只要;如果”。
如:I’ll let you use the car only if you keep it in good condition. 只要你把车保养好,我就让你用。
(4) as/so long as引导的条件状语从句as/so long as意为“只要;如果”。
如:As long as it doesn’t rain, we can play. 只要不下雨我们就能玩。
(5) provided (that)/providing (that)引导的条件状语从句provided (that)/providing (that)意为“如果;只要”。
如:I will agree to go providing (that my expense are paid.) 假如为我负担费用,我就同意去。
(6) once引导的条件状语从句,意为“一旦”。
Once you decide, you’d better not regret. 一旦你决定了,最好别后悔。
【例题精讲】例1.1、The WTO cannot live up to its name _____ it does not include a country that is home to one fifth of mankind. A.as long as B.while C.if D.even though【参考答案】C【思路解析】从句子意思可知,是一个条件状语从句。
中考英语语法专题 目的和结果状语从句讲 解+练习目的和结果状语从句一、目的状语从句用从句来表示主句行为或事件发生的目的,这个从句就是目的状语从句。
常用引导词:so that, in order that 两者可互换Mulan dressed like a man so that she could join the army. 为了能够参军,木兰穿戴成男人的样子。
I got up very early in order that I could get to school on time. 为了能按时到校,我很早就起床了。
从以上例句可看出,目的状语从句有一个特点:从句中一般都含有表示可能性的词语,比如 could。
其他还有 will, would, can 等。
二、结果状语从句用从句来表示主句行为或事件发生的结果,这个从句就是结果状语从句。
常用引导词:so that, so ... that, such ... that 1、so that 意为“结果是……”,从句中一般不出现表示可能性的情态动词;通常用逗号与主句隔开;He got up late, so that he didn’t catch the early bus. 他起晚了,结果没赶上早班车。
2、so + adj./adv. + that 从句,意为“如此……以致于……”;Iwas so careless that I forgot something important. 我真是粗心,以致忘了重要的事情。
He speaks so fast that I cannot understand him. 他说话太快了,以致我不能理解他的意思。
3、such ... that ... 意为“如此……以致于……”,常见结构如下: (1)such + adj.+ n. 复数形式+that 从句; (2)such +adj. +不可数 n. + that 从句; (3)such +a/an +adj.+ n. 单数形式+ that 从句 = so + adj. + a/an + 单数名词 + that 从句 He had such long arms that he could almost touch the ceiling. 他胳膊那么长,几乎能摸到天花板。
中考解密专项之—状语从句创作人:历恰面日期:2020年1月1日状语从句是一较大的语法工程,也是近几年中考题中常见的一个重要试点。
中考中已考察了时间是、让步、地点、条件、目的等状语从句,这些从句仍是今后中考热点,学生们应该充分准备已引起重视。
在复合句中,修饰主句中的动词、形容词或者副词等的从句叫做状语从句,状语从句可置主语之前,也可置主语之后。
前置时,从句后用逗号与主句分开;后置时,与主句之间无标点符号。
状语从句根据它表达的意思可分为时间是、原因、目的、结果、条件、比拟、地点、让步、方式等九类。
〔一〕时间是状语从句(1)表示时间是的状语从句可由when, as, while, whenever, after, before, till (until), since, once, as soon as (或者the moment ), by the time,等连词引导。
e.g. When I came into the office, the teachers were having a meeting.While I was watching TV, the bell rang.As soon as she came in the classroom, the bell rang.(2)主句为将来时,从句用一般如今时代替。
e.g. Whenever we’re in trouble, he’ll help us.〔二〕原因状语从句(1)引导这类从句的最常用的连词是because, since, as , now that〔既然〕等e.g. I couldn’t stay longer, because I don’t have enough money.As it is raining, I will not go out.Since he moved to the town, he didn’t came back.其中要注意:对because 原因状语提问用“why〞because, since,as, for的区别:because 从句所表示的是对方不知道的直接的原因,因此在答复以why引导的特殊疑问句时只可用because,而as, since 引导的从句却不可;as,since从句所表示的往往是对方的原因;for往往用于附加理由证明。
九年级上册英语八单元2b知识点总结英语作为国际交流的重要工具,在九年级的学习中占据了重要的位置。
