➢ 考点揭密
在复合句中修饰主句中的动词、形容词或副词或 句子，起状语作用的从句。由从属连词引导，从属连 词在从句中不充当句子成分。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。

2.条件状语从句
(1)引导词：if,unless.
e.g. If I am free, I will call you.
（“大家都在这里”的原由已为人们所知）
..........

for往往用于附加理由证明。所说的理由是一种补充说明。 分句前常有逗号，其引导的分句不可放于句首。
例句：It’s spring now, for the flowers are out.
Practice:
1. Why hasn’t Mr. Li come to work today. ---- _D___he has gone to Beijing to have a meeting.

unless是从属连词，它引导条件壮语从句，译作 “除非……否则的话”

➢ 中考考点设置
1.时间状语从句 (1)引导词：when, while, as, before, after,
as soon as, until/till, since.

3.原因状语从句
(1)引导词:because, since, as.
(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：
..........
13
① because 从句所表示的是对方不知道 的直接的原因，因此位于主句前或主句后.
③ since用来表示比较勉强的理由和原或原由已为人们所
知。 e.g. Since you can’t answer the question,
（原由已为人们所知）I’ll ask someone else.
e.g. Since everybody is here, let’s bigin the meeting
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。)
(3)if...not与unless(=if…not…) 及or的同义句转换。

例句. Hurry up, or you will be late.
① 小结: so+adj+a/an+n(单数）+that… such+a/an+adj+n(单数）
Practice+:that…
1.It is _A__small a room ___it can’t hold so many
People. A. so… that, B. such…that…
=It is __B_ a small room ___it can’t hold so many People. A. so… that, B. such…that…
e.g. I didn’t leave until/till/before she came back.（leave是个短暂性动词）
② till/until 在肯定句中表示“直到为止” 主 句中动词用延续性动词
e.g. I waited till / until he arrived.
(wait是一个延续性动词）
(3)so与such的区别
例句: She is so great a father that we all like him. so+adj +a+n(名单) +that 例句: It is so red an apple that I want to eat it.
so+adj+an+n(名单) +that
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. 14

4. I will not watch TV until I finish my homework .
e.g. I will tell him when he comes back.
e.g. I won’t go to bed until I finish my homework.
注意
时间壮语从句中若用一般将来时，从句
则用一般现在时表示将来，即遵循“主将 从现”的原则。
