问题
选择题
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
答案:A
题目分析: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。
