请问各位英语达人 During this period all the students were actively participating
During this period all the students were actively participating.were actively participating.是过去式的进行时吗?
答
这就话是本身是个病句,因为 During this period 是时间状语,all the students 是句子的主语部分,谓语动词其实是系动词were.在这个句子,是主-系-表结构的.只不过表语用的是过去进行时,表示正在发生的动作.participati...不会吧是金山词霸的原句啊！你查查
