不定式的形式中进行式是哪两个?
一个是to be doing,另一个是to have being doing还是to have been doing?
新东方的网络课程上写的是to have being doing
望高手作答,谢

赞同楼上,没有to have being doding 这样的形式
to be doing是不定时的现在进行时
to have been doing 是不定时的现在完成进行时

to have been doing
我学了这么多年英语了 从来没见过to have being doing

to have been doing
没有to have being doing的形式,应该是网络课程的资料有误
