Question

Danny ________ hard for long to realize his dream and now he is popular.

1. A.
   works
2. B.
   is working
3. C.
   has worked
4. D.
   worked

Answer 1

C
思路分析：根据时间状语for long和后面的now he is popular，可知Danny是“已经努力工作了很长时间”，故应用现在完成时态。所以选C项。
【点评】该题考查现在完成时态，难度适中。现在完成时态是表示这一动作从过去开始，一直持续到现在，并对现在造成一定的影响和结果。
