e.g. If I am free, I will call you.

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.

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。
