where引导定语从句时，从句前应有一个表示地点的名词作先行词；而状语从句前则无需先行词。

状语从句精讲及练习及答案
状语从句精讲及练习及答案状语从句由从句担任的状语，在句子中可修饰谓语（或其它动词）、形容词、副词或是整个句子，它可以用来表示时间、地点、原因、目的、结果、条件、方式、比较、让步等。
状语从句是一较大的语法项目，也是近几年高考题中常见的一个重要试点。
高考中已考查了时间、让步、地点、条件、目的等状语从句，这些从句仍是今后高考热点，应作充分准备。
同时对方式状语从句也应引起重视。
（一）时间状语从句表示时间的状语从句可由when,as,while,whenever,after,before,till(until),since,once,as soon as(或the moment),by the time,no sooner…than,hardly(scarcely)…when,every time等引导。

e.g.He is disappointed because he didn't 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wherever等。

2.原因状语从句原因状语从句表示主句中动作或状态发生的原因或理由, 可位于主句之前,之后或插在主句中间。
主句表示结果, 从句表示原因, 主要由because, as, since, for,seeing ( that), considering ( that), now (that), in that, not ... because 等引导。
1) because“因为’’, as‘‘由于”, since “既然”, for“因为”because意为“因为”, 表示直接的原因或理由, 着重点在从句, 用于回答why,语气最强。
He is absent today because he is ill.当主句为否定句时, 从句because须用逗号与主句隔开, 否则容易引起歧义。
I didn’t visit him, because I wanted to borrow some books.我没去拜访他, 因为我想借几本书。
I didn’t visit him because I wanted to borrow some books.我不是因为想借几本书才去拜访他的。
as意为“由于”, 表示十分明显的原因, 所引导的从句常位于主句之前, 有时也可位于主句之后, 一般说明因果关系, 着重点在主句, 原因或理由只是附带说明, 不用于回答why的问题, 常用于口语。
As it is snowing, we shall not go to the park.As this book is written in simple English, it is suitable for beginners.since意为“既然, 由于”时表示对方已知的、无须加以说明的既成事实的理由, 只是一个附带说明。
since = as it is the fact that ...全句中心在主句。
如从句表示的原因不是确定的事实, 就不能用since,通常用because.Since everybody is here, let’s begin our discussion.Since you seem to know them, why don’t you introduce me to them?for是一个并列连词, 由for连结的表原因的句子常看作并列句, 它只提供一些补充说明或对前一个分句加以解释, 不可前置。
与because 不同的是:because引导的从句位置可前可后, 而for引导的分句只能后置, 且往往须用逗号或分号与前一个分句分开。
I didn’t go to see him, for a heavy snow was falling.The days were short, for it was now December.有时, for引起的从句并不表示原因, 而是表示一种推断或解释, 而because则不能。
Someone in the house must be ill, for a doctor has just come out.He couldn’t have seen me, for I was not there.一、填入恰当的连词1. I didn’t go to school yesterday _________ I was ill.2. ________ everybody is here, let’s begin our meeting.3. ________ you are in poor health, you should not stay up late.4. I asked her to stay to tea, ________ I had something to tell her.5. ________ all the passengers are here, why don’t we start at once?6.

Since8. As2) 用下列短语引导:seeing (that) “鉴于, 既然”, considering (that) “考虑到”now (that)“既然”, in that “因为”, not ... because “不是因为”not that……but that “不是因为……而是因为, ’seeing that与considering that同义, 含义近似since,所引导的句子中心在主句, 重在强调结果。
Seeing that the weather is bad, we’ll stay at home.Considering that they are newcomers, they’ve accomplished a lot.now that的含义与since(“既然”）接近, 区别在于:since表示原先已存在的情况, 而now that 表示由于新情况的出现而促成某事发生。
Now that it has stopped raining, let’s start at once.Now that you are all here, let’s try to reach a decision.in that作“因为”解时, 由于介词in的含义是指“在……方面”, 有限制作用, 因此多指由于某一方面的原因或理由, 不能位于句首。
I like the city, but I like the country better in that I have more friends in the country.I could understand his point of view, in that I’d been in a similar position myself.not ... because意为“不是因为”, 该结构中的not否定because。
She didn’t marry you because you had money.她不是因为你有钱才嫁给你。
The machine didn’t stop because the fuel was used up.机器不是因为燃料耗尽才停下来的。
not that ... but that作“不是因为……而是因为”解。
