从句的用法和技巧。

02
用法说明
03
though和although在从句中不能与but连用,但可以与 副词still和yet连用。
04
as引导的让步状语从句需要部分倒装,即将表语、状语或 动词原形提到as前面。
05
even if和even though引导的从句表示强调的让步,意 为“即使,尽管”。
06
whether...or...和no matter+疑问词引导的从句表示“无 论...都...”,在句中位置灵活。
状语从句的结构和特点
状语从句通常由从属连词引导,从句中的谓语用非谓语形 式(不定式、分词、动名词等)。不同类型的状语从句有 不同的结构和特点,如时间状语从句常用when, while, as 等引导,条件状语从句常用if, unless等引导。
状语从句与并列句、复合句的关系
状语从句与并列句和复合句有密切关系。并列句由并列连 词连接两个或两个以上的简单句,而复合句则包含一个主 句和一个或多个从句。状语从句可以作为复合句中相反的假设条件,主句说明在这个假设条件下会出现的结果。常用if引导, 从句和主句的谓语动词都要用虚拟语气。

小结: till, until和not…until: 1.until/till从句用于肯定句时,主句的动词
是延续性动作,意为“某动作一直延续到某时间点才停 止”。如: We waited until/till he came. (wait 是延续性动词) 2.用于否定句时,主句谓语动词是非延续性动词,意为 “某动作直到某时间才开始”。此时till/untill可用before 代替如:
He won’t go to bed until her father returns. 3.till不可以置于句首,而until可以。如:
Until you told me I had no idea of it. 4.not…until句型中的强调和倒装说法:
It was not until you told me that I had any idea of it.
got worse.
c.since从句中用一般过去时,主句用现 在完成时。
It’s / It has been + 一段时间 + since + 时间状语从句”中,译作“自从…以 来, 已经…(时间)了” d.as soon as遵循“主将从现”的原则。 主句中若用一般将来时,从句则用一般
现在时表示将来.
考点揭密
在复合句中修饰主句中的动词、形容词或副词, 起状语作用的从句叫状语从句。状语从句可置主句之 前,也可置主句之后。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。
状语从句可分为时间、原因、目的、结果、条件、 比较、地点、让步、方式等九类。
e.g. If you go to the party, you will
e.g. As the water was not deep, we were able to
breakfast, he heard the doorbell ring.
While he was watching TV, the boy fell asleep. b.as则强调主句和从句的动作在同一时间进行(一 边...一边);也可表示“随着……”.
She sang as she walked along. As the election approached, the violence(暴行)
(2)对because 原因状语提问用“why” (3)because 不能与so连用。 (4)because,since,as,for的区别:
① because 从句所表示的是对方不知道 的直接的原因,因此在回答以why引导 的特殊疑问句时只可用because,它引导 的从句可以位于主句前或主句后.
right now.除非你现在出发否则的话年上学就会迟到的。 e.g. You will not succeed unless you work hard. (2)遵循“主将从现”的原则, (即主句若为一般将来时, 从句用一般现在时代替将来。)
考点设置
3.原因状语从句
而as,since 引导的从句却不可;
例句: Li Hong didn't go to school
yesterday,because he was ill.
Why are you standing here? ---Because I’m waiting for my uncle.
② as从句所表示比较明显的原因和理由(由于,既然) 这种原因一般是大家知道的,一般从句说明原因,主 句说明结果。其从句位于主句之前,
2.
(1)引导词:if,unless(=if...not).
e.g. If I am free, I will call you.
e.g. If it doesn’t rain, we will go for a walk. unless是从属连词,它引导条件状语从句,译作 “除非……否则的话” 、 "如果....不” e.g. You will be late for class unless you start
Not until you told me did I have any idea of it.
practice:
1. I will go to bed as soon as I __C__my homework. A. will finish B.finishing C. finish
4. I will not watch TV until I finish my homework .
have a good time. e.g. You will have a good time if you
go to the party.
复合句由一个主句(Principal Clause)和 一个或一个以上的从句(Subordinate Clause)构成。
主句是全句的主体,通常可以独立存在; 从句则是一个句子成分,不能独立存 在。
从句不能单独成句,但它也有主语部分 和谓语部分,就像一个句子一样。所 不同在于,从句须由一个关联词 (connective)引导。g
考点设置
1. (1)引导词:when, while, as, before, after,
注意: as soon as, until/till, since. a.while所引导的时间状语从句中的时态常用进行 时态。如: When/While he was eating his
