Question

It’s the first time that she has been to the United States, __?

A. isn't she B. hasn't sheC. isn't it D. hasn't it答案?解释?

Answer 1

C

反间疑问句，对前面的事实提出翻译疑问句。所以是isn't it.

解析：
在反意疑问句中，对于复合句的反意是通常情况下根据主句相反（当主句中主语为I/We，谓语动词为think, be afraid, be sure, expect, suppose等，属于特列，这时要反从句 ）。

此题中就是普通的复合句实际是It's the first time (that) she has been to the United States.也就是说It's the first time是主句部分，所以反意疑问句中要根据主句部分反意，所以选C

Answer 2

C. isn't it 附加问句我对主句It is.....进行的反问，所以用主句中的动词is .祝进步！

Answer 3

我个人感觉啊，能提出反问的俩地方一个是对it is 一个是 she has, 所以AD排除
强调的是那次她去美国是 “第一次”，所以大概应该是it isn't吧……
