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(shí)間狀語for some time以及后一分句的動詞時(shí)態(tài)可知,選項(xiàng)動詞動作強(qiáng)調(diào)到現(xiàn)在為止并仍在繼續(xù),故應(yīng)排除選項(xiàng)A、C。由于選項(xiàng)B現(xiàn)在進(jìn)行時(shí)不可與一段時(shí)間狀語連用,所以排除選項(xiàng)B,選D現(xiàn)在完成進(jìn)行時(shí)。
