问题补充：

It is the first time that Michel the Summer Palace.

A. is visiting

B. visits

C. has visited

D. will visit

答案：

A. is visiting

B. visits

(答案→)C. has visited

D. will visit

解析：句意：这句话的意思是：这是Michel第一次参观颐和园。这里使用了固定句型:It is the first time+从句，从句的谓语是用现在完成时，如果是It was the first time+从句，从句的谓语就是had done，所以选C。
