keep sb being done和 keep sb done有什么区别？ask sb to d

keep sb being done和 keep sb done有什么区别？ask sb to do sth里做的动作是sb 嘛？那可不可以用ask sb to be done呢？

推荐答案 2016-05-04

keep sb being done: keep sb表示保持某人某一状态，being done是动词现在分词做形容，表示被完成，语义不大通顺
keep sb done 保持某人完成
ask sb to do sth 让某人做某事，动作是sb的
ask sb to be done ,让某人被做
楼主要学习一下被动语态 be动词加动词过去分词为被动追问

但是有时候说的不定式不也包括被动吗…有很多不定式结构不也可以换成被动

see sb done能换成see sb be done么？为什么need doing能换成need to be done呢
