Question

The students were all standing by the swimming pool, ______ swimming suits.

A．all of them worn

B．all were wearing

C．all of whom wearing

D．all wearing

Answer 1

D

试题分析：考查非谓语动词和定语从句。句中有逗号，可能是非限制性定语从句，选A、B的话，是并列分句，但是没有and连接两个分句，排除A、B；选C的话，all of whom后面应该是一个完整的句子，缺少were，排除C；D项中的all指代the students，和wear是主谓关系，应该使用现在分词表示伴随状况，故选D。
