解释下这个语法..

当主句是第一人称时，要与从句一致。
I believe that the will win, won't he?
类似的还有：I think,I suppose,I figure等。但是，主语不是第一人称时，就要与主句一致。
例如：He doesn't think that I am right, does he?

I believe that he will win，won't he ?

i believe that he will win, won't he?
我相信这种主句都要对从句提问，还有i think i suppose 之类的，因为主句我相信这一点没有任何疑问，说话人心知肚明，只有从句内容才是说话人想问的，所以以后看到就要对从句提问。
主句不是i开头比如he think 之类就得提问主句
