(单选题)

He hesitated for a moment before kicking the ball, ______ he could have scored a goal.

A.therefore

B.however

C.besides

D.otherwise

参考答案：D

参考解析：

考查词义辨析其他。句意：他踢球之前犹豫了一下，否则他就能得一分了。therefore意为“因此”，表因果；however意为“然而”，表转折；besides意为“另外”；otherwise意为“否则”；he could have scored a goal是与过去事实相反的虚拟语气，otherwise是含蓄条件句的连词，符合句意，故选D。
