It seems that water from this tap ________ for some time.We'll have to take it apart to put it right.

Ahad leaked Bis leaking

Cleaked Dhas been leaking

 

D

【解析】根據(jù)句中時間狀語for some time以及后一分句的動詞時態(tài)可知,選項動詞動作強調(diào)到現(xiàn)在為止并仍在繼續(xù),故應(yīng)排除選項A、C。由于選項B現(xiàn)在進行時不可與一段時間狀語連用,所以排除選項B,選D現(xiàn)在完成進行時。
