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：根據(jù)時間狀語for long和后面的now he is popular，可知Danny是“已經(jīng)努力工作了很長時間”，故應(yīng)用現(xiàn)在完成時態(tài)。所以選C項。
【點評】該題考查現(xiàn)在完成時態(tài)，難度適中。現(xiàn)在完成時態(tài)是表示這一動作從過去開始，一直持續(xù)到現(xiàn)在，并對現(xiàn)在造成一定的影響和結(jié)果。
