Have you ever been to Shanghai Mary? -- Yes. I there for three clays with my parents

问题补充：

-- Have you ever been to Shanghai, Mary?

-- Yes. I there for three clays with my parents last month.

A. have gone

B. have been

C. went

D. was

答案：

A. have gone

B. have been

C. went

(答案→)D. was

解析：考查时态。“玛丽，你去过上海吗？”“是的。我上个月和父母在上海待了三天。”根据last month可知，用一般过去时。Go不能与一段时间连用，be there“在那里”。故选D。
