as the light turned green ,i stood for a moment,not___,and asked
As the light turned green,I stood for a moment,not _________,and asked myself what I was going to do.[2007 湖南卷]
A.moved B moving
C.to move D.being moved
为什么选B,不选A?stood 和asked是并列的谓语,因为有and连接,但是not moving是一个插入语,看它是主动还是被动形式,主动用doing,被动用being done 这里用动词的分词形式使 not moving 作为 stood 的伴随状态,与stood 动作同时发生
