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：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。

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。
