—Mr. Black, may I leave now?
—Well, if your work ________, you can go home.
A．finishesB．is finishedC．has finishedD．will be finished
B

試題分析：根據(jù)題意，本句的意思是“如果你的工作完成了，你可以回家�！北揪涫且粋�以if引導的條件狀語從句，主句用將來時，從句用一般現(xiàn)在時，根據(jù)can可知，本空應(yīng)該用一般選擇時，故排除CD；又因為工作是被完成大的，應(yīng)該用被動語態(tài)。所以本題選B。
點評：本題牽扯兩個知識點，一個是條件狀語從句，一個是被動語態(tài)。如果忽略其中任何一個，就會犯錯誤。本題設(shè)計較好，能很好的考查學生的能力。
