_many times,but he still couldn't understand itA,Having been told B, Though he had been told C,He was told D,Having told选择哪一个，为什么？

Answer 1

正确答案： C讲解 ： 误：Having been told many times，but he still couldn’t understand it。
正：He was told many times， but he still couldn’t understand it。
注意：（1）分词作状语时，逻辑主语即句子的主语;否则要用从句或独立主格结构来表示。
例如：
Looking out of the window，I saw lots of people there。（＝When I looked out of the window，I saw lots of people there。）
我往窗外一看，看见那儿有许多人。 （looking out of the window的逻辑主语，就是句子的主语I。）
也就是说，but作为一个转折词连接的是句子而不是非谓语句型。

Answer 2

首先，主语他和告诉 的关系是 他被告诉 ，所以tell应该用被动态，所以可以排除D其次， 因为原句中有了but ， 就不能和though合用，所以排除BA与C， A,现在完成时更强调已经被告诉好几次，但是他还不知道。 选A

Answer 3

选A.C是错的
