※till, until和not…until：
1.until/till引导时间状语从句用于肯定句时，主句的动词是延续性动词，表示动作或状态一直持续到until/till所表示的时间，意为“某动作一直延续到某时间点才停止”。如：
We waited until he came.
2．用于否定句时，主句谓语动词是非延续性动词，从句为肯定，意为“某动作直到某时间才开始”,如:
He won’t go to bed till/until she returns.

2. 地点状语从句
地点状语从句由 where, wherever 等引导。
例如：

3.条件状语从句
由if（如果）, unless（if...not，除非）, so/as long as （只要）等引导，谈论的是一个有可能发生的事实及其产生的相关的结果，主句用现在时，从句也用现在时；主句用过去时，从句也用过去的某种时态。
主将从现具体地讲，主句是一般将来时(包括祈使句和含有情态动词can, may, must等)，从句也用一般现在时。
①
We won’t wait for him, if he doesn’t come before 12o’clock.
如果他12点之前还不回来，我们就不等他了。
We won’t wait for him, unless he comes before 12o’clock.

中考题型
Ex3总结： 这里考的是两个if -从句中的不同时态
第一个if 从句是条件状语从句， 要用一般现在时表将来， 也就是see
第二个if 从句是宾语从句， 不可用一般现在时表将来，如表将来（注意状语"明天”）要用将来时也就是will go
条件状语从句
如果
是否
4.原因状语从句
原因状语从句通常由because, as, since, 等词引导。
because语气较强，用以回答why问句。④
－Why are you late again today
－Because I've got a bad cold.
as语气较弱，较口语化，所表示的原因较明显。
As I didn’t know the way, I asked a policeman.
由于我不知道路，我问了一个警察。
since语气较弱，常表对方已知的事实，相当于汉语的“既然”。
Since you can't answer the question, you might ask someone else for help.
既然你不能回答这个问题，你可以找其它人帮助下。
because和so不能同用在一个句子里 ⑤,
英语中“因为”和“所以”不能同时出现在一个句子中
如：
我们不能说：
Because it rained hard, so we stayed at home.
因为雨下得很大，所以我们待在家里了。
应该说：
或
It rained hard, so we stayed at home.
Because it rained hard, we stayed at home.
because of和because的区别⑥
① because of后加名词代词或动名词或短语，不加句子，
而because加句子，例：
Because of his illness, he didn’t go to work.
因为他的病，所以他不能上班了。
Because he was ill, he didn’t go to work.
因为他生病了，所以不能去上班了。
形象比喻：because of 长，后+单词或短语；because短，后加句子。
1. I didn’t buy the dictionary yesterday ______ my aunt would give me one.
A. until B. because C. if D before
2. ---- Why did you come to school late this morning
----- ______ I watched the football World Cup until 12 o’clock last night.
A. If B. Because C. Since D. Though
中考题型
总结： 重点掌握because 的用法 （注： because 和so 不能同时用在一个句子中）

He got so little pay that his family had to live on welfare money.
It’s such a good chance that we mustn’t miss it.
他如此小以致于他不能上班。
他工资很少，他的家人不得不靠救济金生活。
机会这样好，我们决不能失掉。

他太小以至于不能上学。
