3、t to sleep. （二）缘由状语从句缘由状语从句是表示缘由或理由的,引导这类从句的最常用的连词是 because, since, as , now that（既然）等, for 表示因果关系时（它引导的不是从句）为并列连词,语气不如 because强；e.g. He is disappointed because he didnt get the position. As it is raining, I will not go out. Now that you mention it, I do remember. （三）地点状语从句引导地点状语从句的连词是 where 和 where
4、ver 等；e.g. Sit wherever you like.

5、e he should miss the train. （五）结果状语从句结果状语从句是表示事态结果的从句,通常主句是缘由,从句是结果；由 so that （从句谓语一般没有 情态动词） , so that, such that 等引导；e.g. She was ill, so that she didnt attend the meeting. He was so excited that he could not say a word. She is such a good teacher that everyone admires her. （六）条件状语从句条件状语从句分真实性（有可能
6、实现的事情）与非真实性（条件与事实相反或者在说话者看来不大可能实现的事情） 条件句；引导条件状语从句的词（组）主要有 if, unless, so as long as, on condition that, so as far as, if only = if ；留意：条件从句中的 if 不能用 whether 替换；e.g. If he is not in the office, he must be out for lunch.

10、般将来时,从句通常用一般现在时表示将来；e.g. We ll go outing if it doesnt rain tomorrow.I ll write to you as soon as I get to Shanghai. 2、有些时间、地点、条件、方式或让步从句,假如从句的主语与主句主语一样（或虽不一样,是 it）,从句的谓语又包含动词 be ,就可省略从句中的“主语 + be ”部分；e.g. When he was still a boy of ten, he had to work day and night. If you are asked you may come in.
11、 If it is necessary Ill explain to you again.3、留意区分不同从句：引导的是什么从句,不仅要依据连词,仍要依据句子结构和句意来判别；以 where为例,能引导多种从句；e.g. You are to find it where you left it. （地点状语从句）Tell me the address where he lives.（定语从句,句中有先行词）I don t know where he came from.（宾语从句）Where he has gone is not known yet. （主语从句）This place is w
