英语中的省略为了避免重复，英语句子中某些部分可以省略。
常见的省略有以下几种：一、状语从句中的省略在时间、条件、让步及比较状语从句中，如主句和从句主语一致（或从句主语是it），且从句含be动词时，可将从句中的主语和be动词省略，从而构成“连词+ 分词/形容词/副词/介词”结构。
这里常见的连词有when/while/as/if/unless/once/although/though/than等。
When (water is )heated, water is turned into vapor. 水加热时变成气体。
He works very hard though（he is）rather weak. 他尽管体弱，但他十分努力地工作。

once后省略了the research is begun ②B。
比较状语从句中的完整形式是：than they are commonly supposed。
二、并列结构的省略1.并列结构一般由and, or, but等连接，他们可以连接单词、短语或分句，其中相同成分出现时可以被省略。

2. When ____, the museum will be open to the public next month.A. completedB. completingC. being completedD. to be completed答案：A解析：原句完整形式为When it is completed，这里it指代the museum。

3. The man ____ by the window is my English teacher.A. standingB. standsC. is standingD. to stand答案：A解析：原句完整形式为The man who is standing by the window is my English teacher。
