【题目】He ________ in designing the cover of this journal for quite a few days, and I wonder when he can finish it.
A.is involvedB.is involvingC.has been involvedD.has involved
在线课程【答案】C
【解析】
考查动词语态和时态。句意：他专心设计这个杂志的封面很多天了，我想知道他什么时候能完成。短语be involved in意为“专心；涉及”，根据句中“for quite a few days”可知时态为现在完成时。故选C。
