状语从句复习

3.till 和until
1)一般可互换2)置于句首时,只用until
注意:
1）当主句谓语动词是延续性的,要用肯定形式until...... / 当主句谓语动词是短暂性的,要用否定形式not...until...
Wait until he comes

3) not until用于强调句
e.g. It was not until she finished her exercises that she went home.

4.when 和while
when从句中既可是延续性动词(段时间),也可以是短暂性动词(点时间)
while从句中只能是延续性动词(段时间)
e.g. While I was reading she came in (=when)

5.since 引导的状语从句(从句常用一般过去时.主句常用现在完成时)
常见句型: It is (has been)+ 时间段+ since sb did sth 自从…以来,有多长时间.

三、原因状语从句
1.引导词: because （经常用于回答why的提问）

2) He is ill , so that he is in bed. (结果)
2. 在so (such) …that 结构中

2 状语从句的省略
时间状语从句，地点状语从句，条件状语从句，方式状语从句常可用于状语从句的省略，但需符合以下前提条件中的一个：

2）当状语从句为it is (was) + adj / n / 介词短语结构时，常省略it is (was)
eg. 1). If (it is) possible, I’ll visit you.

3). Once (he is) there, he’s lost.
4). Although (he was) frightened, he managed to run away.

状语从句高考考点高考状语从句讲解 语法专题 状语从句 考点归纳 考点一：对when，while，as，since等词的辨析 when，while，as，since在引导时间状语从句时的区别可参见下表： 和从句动词所表示的动作或状态是同时发生的，它引导的从句用延续性动词，若从句中是非延续性动词，不能用while。 表示“一边……一边”的意思时用as或while。 As/While she was cooking she was singing songs、 She sang as she cooked、 当主句谓语动词表示短暂动作，而从句动作可以持续一段时间时，三个连词都可以用。 Tom poke his leg while/when/as he was playing football、注意： ① when也可用作并列连词，其意义为“就在那时，这时”，相当于and at this/that time，常用下列句式中： We were having a meeting when someone poke in、 We were about to set off on our way，when it suddenly began to rain、
He had just left the room when it rained、 另外when还可表示原因“既然”。 It was foolish of you to take a taxi when you could easily walk there in five minutes、 ②while除引导时间状语从句外，还可引导让步或条件状语从句及作并列连词连结两个并列的简单句。如：While he was respected，he was not liked、 There will be life while there is water and air、 He is a worker while I am a doctor、 since引导从句时在主句是现在完成时的条件下，从句若为非延续性动词的一般过去时，表示从该动作的完成时刻算起，因此动词的语法形式与词义一致，是肯定意义；若从句动词为延续性动词的一般过去时，表示动作或状态从最后一次发生到现在。因此其含义与动词的词义恰好相反，具有否定意义，若从句延续性动词用现在完成时，则动词的语法形式与词义一致，是肯定意义。 I haven”t heard from her since she left Beijing、 自从她离开北京后，我从未收到她的信。 I haven”t written to her since she lived in London、 自从她离开伦敦以后，我从未给她写信。 Since I have been at this school we have three headmasters、

定义——在复合句中由从句表示的状语称作状语从句，状语从句由从属连词引导，也可以由一个起连词作用的词组引导，有时甚至不需要连词而直接和主句连接起来。 类型——时间、地点、原因、结果、条件、目的、让步、方式、比较状语从句。 1.引导词when, while, as, as soon as, once, before, after, every time, each time, since, whenever, ever since, until ,till等。 2.whenever, each time, every time的用法。注：whenever=no matter when every time / each time 每次，whenever 每当······时，表示习惯性、经常性的动作。 Whenever we met with difficulties, they came to help us. Each time he came to town he would visit our school. Eevery time I went to his house, he was out. 注：whenever=no matter when whenever既可以引导时间从句也可引导名词性从句，no matter when只可以引导时间状语从句。 It does not matter whenever the party begins. 3.before的汉英表达 1）before的基本含义是“在·····以前” The train had left before he got to the station. 注意：与before对应的是after引导的时间状语从句，表“在·····之后”。 2）强调从句动作发生的晚或慢，before可译成“（后）·····才” 句型：It was + 时间段+ before·····It will be + 时间段+ before····· It seemed long time before my turn came. It was a long time before I got to sleep again. It will be five years before we meet again. 3)主句中谓语动词是否定形式，before可译成“就”、“便”、“快” 句型：It was not +时间段+ before ···· It won’t be + 时间段+ before ····（从句谓语动词用一般现在时） It was not long before he got to know it.
