Children were seen _____ their hands and ___a song when I came into our classroom.A clapped;sangB clapping;singingC clap;singD to clap;sing
B clapping;singing 为正确选项.
知识点延伸-----------
(1)句子有when .表示过去某个时间点的时间状语,故clap和sing都是那个时间正在发生的动作,用进行时态;
(2)see sb doing sth的被动语态是,sb be seen doing sth.
祝你进步!
选B。。。。。。。。。。。。。。。。。
when 时间状语 是明确时间 所以用进行时
and连接相等成分 所以也用进行时
选B
——FROM【学习宝典】
选择B.当我进入教室时,看见孩子们正在拍手唱歌。
see sb do 看见某人做过某事,省略to的不定式,变被动语态时需要还原to, be seen to do。
但是当see sb doing看见某人正在做...时,被动语态为be seen doing,无to
希望帮到你
B see doing sth.
