请问 去掉 句中but 后 怎么选

____ but he still could not understand it.A.Told many times B.Having been told many timesC.He has been told many times D.Though he had been told many times请问 去掉 句中but 后 怎么选
因为though,but不能连用,不选D
后半句是could,是过去式,前后时态要一致,不选C
同样道理,B项中,Having been told many times是现在完成进行式,故不选
A 只是省略主语和助动词,全句应是He had been told many times,but he still could not understand it.英语中,若前后主语一致,可省略主句主语和助动词.

B
but前后主语一致，所以用被动形式，A 排除
Though，but不能同时用于一个句子，D 排除
but后时态为过去时，C 排除

C
因为有but连词，所以要连接两个完整句子，因为是“被告知”，所以用被动。
如果选B，它是一个状语，不应有but，而应换为“，”。

B AB 都是省略主语的,所以主语应该是he,他,应该是被告诉,所以A不行,D因为已有but就不能再有Though 至于C,因为C是一完整句子,题干也是完整句子,所以一定要有逗号隔开

C

我觉得应该选择C，这个应该考的是现在完成式的被动语态。同时but连接两个句子。
