Question

--- When ________?

--- I ________ two days ago.

1. A.
   did you skate; skated
2. B.
   do you skate; skate
3. C.
   have you been skating; have been skating
4. D.
   have you skated; have skated

Answer 1

A
考查了现在完成进行时的用法和一般过去时的用法。在单纯谈一个过去的动作，不涉及对现在的影响，常用一般过去时，且有具体的时间状语，用when提问，回答就有具体的时间，用一般过去时，同时two days ago表明应用一般过去时；故答案为A。
