Question

—_________ to Hong Kong?

—Yes, but only once.

—When __________ there?

—Two year ago.

A．Did you go; did you go

B．Have you gone; did you go

C．Have you been  did you go

D．Have you been; have you been

Answer

C

【解析】

试题分析：句意：--你去过香港吗？--是的，但是仅仅一次。--你什么时候去那的？--两年之前，根据下文,but only once可知上文应该用完成时have been to 表示去过某地；根据下文Two year ago的回答可知上文用一般过去时态。 故选C。

考点：考查动词的时态
