_____________he can quickly seize the chance of business.
A having been well informed
B to be well informed
C having well informed
D to have been well informed
答案是A 为啥啊谢谢
几位大哥给出了答案但还有一事不明同样表被动 B 为啥不行啊

后半句意思为他能够快速的抓住商业机会，前半句应为已经具备的能力，所以应该用完成时的被动态，答案是a

选 A，必须用被动语态，而且表示原因。

被动语态。
关键是inform这个动词的用法。

为什么是There having been? having been done 与done imressed by, having been impressed by being done having been done的区别 having been done和have been done的区别 She has been ill.She is having ___ leave. There having been no rain, the ground was dry. 请问这个句子里的 have been having 是什么意思请问以下的having been completed 有没有这种结构？ having been done 和done作状语的区别
