请问
A. A book has been bought and has been read by me.
B. A book has been bought and read by me.
请问哪句话是正确的，麻烦详细解释一下，谢谢，如果您认为都是错的，那么请给出你觉得正确的回答。
主要是想知道，被动语态这加上时态的时候 应该怎样正确关联 确保其平行关系。
还有一句话，
A. I have done the homework and been tortured by the questions.
B I have done the homework and have been tortured by the questions.
哪句话对呢？要保持句子两边的平行 实在是困惑啊。
