题型：不详难度：来源：

Unless _________ by the police, you should keep silent over the accident.

A．asked

B．ask

C．being asked

D．having asked

答案

解析

试题分析：从by the police可以说明you与ask之间构成被动关系，故排除ＢＤ，另外非谓语动词的省略往往会省略从句的主语和部分谓语，即be动词，故选答案Ａ，也可以将状语从句补全，即Unless you are asked by the police,然后再去掉you are,即可得知答案。
点评：状语从句的省略同时具备下列两个条件: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。从句中的主语和be动词常可省略
