Question

it‘s the third time that John has been late,--?填反义疑问句,为什么hasn't he 是错的.
这也是从句,而i suppose he' seriou,---?反义疑问句就是isn't he.为什么一个改的是从句,另一个改从句就是错的呢

Answer 1

it‘s the third time that John has been late, 是个强调句,强调的是时间the third time,而不是强调John这个人,因此反义疑问也是针对这个来问,用isn't it? 意思是：这都是John第三次迟到了,不是（第三次）吗?而 I suppose he's serious,是个一般的陈述句,就是陈述我的感觉：我觉得他是认真的.因此此反义疑问句应该是：我觉得他是认真的,难道他不是（认真的）吗?相应的英文就是isn't he.
