动词不定式的进行式.
问题描述：
动词不定式的进行式.
我在一本书上看到：
to be doing .表示在谓语动词的动作或状态发生时正在进行的动作.
请问：请给举个英语句子为例.
答
我觉得很好理解啊,就是和进行时的理解差不多
不定式进行式表示动作正在进行,通常与限定动词表示的动作同时发生.
例：
He seems to be following us.(=It seems that he is following us.)
She pretended to be listening attentively.(=She pretended that she was listening attentively.
