Question

-she's never been to Hong Kong，_____?-______,but how she wishes to go there again

Ais she，yes Bis she，no Chas she，yes Dhas she，no

Answer 1

选C.
根据she's never been to Hong Kong中she's，判断该句助动词为has，所以排除A/B.
反义疑问句中，陈述句肯定，附加问句用否定;陈述句否定，附加问句通常用肯定。根据这一规则，C/D均可。
下文语境but now she wishes to go there again可知，she曾去过hongkong，所以第二说话者要先答：yes,she has been to hongkong.缩写成yes

Answer 2

Dhas she，no

Answer 3

选C
最后一空明显是Yes,she has,她去过，还想再去，反问回答看后半部分，肯定就是YES，否定就是NO

Answer 4

D
