典型例题解析
课时训练考点揭密 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
have a good time.
e.g. You will have a good time If you
go to the party.
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.?
?　 e.g. Mother was cooking dinner when
I reached home.( when “当……的时候”）
e.g. While the girl was shopping,
the UFO landed.
（ While “当……的时候”）e.g. Don’t close the window before
you go to bed.(before 在……之前）e.g. As he was reading, he was
listening to the radio.（As “一边……一边”）e.g. After I had done my homework,
I went to bed.e.g. The Greens has lived here since
they came to China.(since 引导的时间壮
语从句若用一般过去时，主句则用现在完成时 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。
?e.g. I will write to you as soon as
I get to Beijing.e.g. I will tell him when he comes back. 注意e.g. I won’t go to bed until I finish my
homework.(3)not...until的同义句替换。
① not…until在否定句中表示“直到……才”，
主句中的动词常用终止性动词, 这时
till/until可用before替换
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）e.g. I didn’t leave until/till/before she
came back.（leave是个短暂性动词）

从句用一般现在时代替将来。)?2.条件状语从句?
(1)引导词：if,unless.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，它引导条件壮语从句，译作
“除非……否则的话” e.g. You will be late for class unless you start
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.
小结:“祈使句+or+一般将来时的陈述句”结构中，
Or表示转折，译作“否则，不然的话”
相当于一个否定的条件状语从句。
相当于If you don’t(can’t)…, you will…

?

Why are you standing here?
---Because I’m waiting for my uncle.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.
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.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,

?
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. As the water was not deep, we were able to
cross the river.(从句说明原因，主句说明结果)e.g. AS I knew he was ill, I didn't call him.e.g. Since everybody is here, let’s bigin the meeting
（“大家都在这里”的原由已为人们所知）e.g. Since you can’t answer the question,
（原由已为人们所知）I’ll ask someone else.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。
