题型：不详难度：来源：

They were all standing on the playground,           white suit.

A．all wearing	B．all wore
C．all were wearing	D．all of whom wearing

答案

A

解析

试题分析：考查独立主格结构：They were all standing on the playground,中间没有连词，说明有可能说是定语从句或独立主格结构，D项用了whom但是又缺少谓语，BC有谓语但是没有关系代词，选A。all是逻辑主语，wearing是现在分词做状语。
点评;此题很容易误选，许多同学会认为句中逗号后是一个非限制性的定语从句，但实质上是错的，原因是空格后根本不是一个句子，因为没有谓语。记住要分析句子成分。
