答案CAD 。 为什么第一道不选D 不是keep sb doing sth 吗。 第二题为什么是A being done不是用在主动且现在发生时的动作吗。
还有第三道。。。。 给我说说，谢谢啦！！~

Answer 1

第一题，Keep sb +adj.+of 是保持informed的状态。这里的informed是adj. 知晓的意思。
第二题，After是介词，其后加V-ing. after being 是“会，可以”的意思
第三题，有什么问题呢？请追问

Answer 2

1.过去分词表状态
2.条件状语从句中的“主将从现”
3.（我想选A）选D大概是因为强调了时间状语“当……时”吧
