It's the first time I have been to the US,______
改反意疑问句,我觉得应该是 isn't it
但答案是haven't I,
到底哪个对呢?
规则里是说要根据主句来改反意疑问句的，网上有好几个例子，把句子里的I've换成She has,后面是isn't it，这个肯定是对的，但改成I have 之后是否情况不同了呢？
大家没有明白我的意思，看下面我找到的规则：
当陈述部分是It (This,That或其他表示时间的名词+ be+the+first time(month 等)+that 从句(that 可省)时，疑问部分与主句的主语和谓语保持一致 .如：This is the third time he has left home,isn't it?Tomorrow will be the second time that I have had to have my TV set repaired again,won't it?

这句话看成2部分
1是It's the first time
2是I have been to the US
第2部分是主要的所以是haven't I.
找到主要部分才是关键
可能说得太白了你听得懂

答案是haven't I.
因为句中的it只是形式主语,真正的主语是I
这句话也是说"我"的情况.

楼上说得对
你可以把这句话换个形式
I have been to the US for the first time . 这一下子就看出来反意疑问句是谁了

1是It's the first time
2是I have been to the US
第2部分是主要的所以是haven't I.
找到主要部分才是关键

恩，这个时强调句，前面的It is 时为了强调第1次

It's the first time ,for the first time ,the first time ,at first 区别?哪个后面加过去时态用it's the first time...that造句? it's the first time 后面为什么要接现在完成时, It's the first time that中 that 可省吗 it's the first time that与sb is the first to do 的区别 It’s the first time that he( )the first prize 用wins还是has won It's the first time that he's ever been abroad .的主句是什么 It's like the first It's the first time for me ______(visit)the Great Wall. It's the first time for me to eat the sweet potato p_____ in this way. 英语翻译it's about time baby it's about the time put yourself first baby put yourself first so don't call me selfish it is the first time 用法英语改错 “It's the first time that he lost a game” it's the first time that后为何加完成时? it's the first time that sb.have done到底是不是强调句 it's the first time that这个句型,后面除了完成时还能其他时态吗? It's the first time that he has been to china.的反意疑问句是什么 it's the first time that i -----to beijing为什么用come,不用have come
