Question

Have you been to West Lake? -Yes,I ____ there las

t summer. 填have been 可以么？

Answer 1

— Have you been to the West Lake?
— Yes, I (went) there last summer.
原因分析：第二句中有了一个具体的过去时间状语last summer，所以就不可以用完成时，而必须用过去时。
又如：
A: Have you been to Beijing? 你去过北京吗？
B: Yes, I went there last year. 是的，我是去年去的。
