Answer 1

This is a good film.I have seen it twice.
(分析：现在完成时常常与表示频度的时间状语连用,
　　如often,sometimes,ever,never,twice,on several occasion等： ）
Have you been to America? Yes,I have.
(分析：根据后面给出的回答说Yes,i have可以推测前面的问句肯定是have引导的,根据选项可以排除A.D选项是说你将要去美国么?意思不对,排除.C选项的前面是对的,后面的gone 在这里表示去过某地但是人不在现在说话者的地方,就是去了某地没有回来.也排除.）
What have you done? I have boiled an egg.
(分析：前面的提问是完成时,所以回答是完成时、然后boil的过去式是直接加ed)
