It's the third time that you have been unable to answer the same question,_________?
A.is it
B.isn't it
C.have you
D.haven't you
首先请分析一下这是一个什么句型:有人说that引导的是定语从句,但我觉得不对.有人说这是个强调句型.问题是反义疑问句究竟是跟主句走还是跟后面的that引导的句子走?
It's the third time that you have been unable to answer the
这个是强调句,It is (was)…that (who)…为结构词,
  假如去掉,剩下部分在语法结构和句子含义上均完整,这一点正是它和定语从句等的本质区别.
  这里面 去掉以后 按正常语序有
  you have been unable to answer the same question the third time.
句子结构很完整,所以是强调句.
强调句型的反意疑问句,后半部分的附加疑问句部分的主语和谓语以及时态要与强调句型本身保持一致.
所以,选B.
