1．比较状语从句中的省略在以than或as引导的比较状语从句中，如果主语与主句的主语一致，则从句主语与谓语（可以是be动词，也可以是行为动词）均可省略；如果从句的主语和主句的主语不一致，则省略其谓语及与主句相同的部分。
如：Production is going up much faster than (it was) before.生产比以前增加得快多了。
Jane can speak Spanish more fluently than Peter (can speak).珍妮讲西班牙语比彼得讲得流利。
Winter in Guangzhou is not so cold as in Beijing.广州的冬天不像北京的冬天那么冷。

I would rather go with you (than stay here).我宁愿跟你一起去。
Are they as keen about it (as we are)?他们对这件事和我们一样这么迫切吗？2．条件状语从句中的省略在条件状语从句中，与主句中相同的部分可以省略。
例如：I am happy if you are (happy).如果你高兴，我也高兴。
If (it is) necessary, I will ask you for help.如果有必要，我将请你帮忙。
[注] 在条件状语从句中，经常使用一些省略了的固定搭配，如：if any, if necessary, if possible, if so, if not, 或if + 介词短语，if/unless/once + 过去分词等。
状语从句的省略
状语从句的省略状语从句的省略是指使语言的精炼将状语从句进行简化。
需满足两个条件: 1.主句和从句的主语一致，或从句主语为it；2. 从句主要动词是be的某种形式。
例如：When ( the museum is ) completed , the museum will be open to the public next year .He’ll go to the seaside for his holiday if (it is ) possible.另外，比较状语从句经常省略。
例如：The higher the temperature (is), the greater the pressure (is ).状语从句的"简化"现象常存在于以下五种状语从句中:①由if, unless等引导的条件状语从句;②由although, though, even if / though等引导的让步状语从句;③由when, while, as, before, after, until / till等引导的时间状语从句;④由as, as if等引导的方式状语从句;⑤由as, than等引导的比较状语从句。
下面针对这五种情形作一归纳。
(1)当状语从句的主语是it,且谓语动词是be时,it和be要完全简化掉。
例如:If (it is) possible, he will help you out of the difficulty.如果可能的话,他会帮你摆脱困境。
You must attend the meeting unless (it is) inconvenient to you.除非情况对你来说不方便,否则你必须出席这次会议。
(2)当状语从句的主语和主句的主语一致时,从句可以将主语和be动词简化掉。
常用于以下几种情形:a.连词+形容词As (he was) young, he learned how to ride a bike.他小时候就学会了骑自行车。
