A.sat B.had sat
C.had been sitting D.was sitting
提示:句意:“你的上衣怎么了?”“刚才我正要下车时,坐在我旁边的那位男士正坐在上边。”when表示的时间可指从句的动作刚刚发生,主句的动作正在进行。
答案:D
讲评:过去进行时表示在过去某一时刻正在进行的动作,本题是通过语境来体现的。
【例2】(2010辽宁模拟) All these gifts must be mailed immediately________ in time for Christmas.
A.in order to have received B.in order to receive
C.so as to be received D.so as to be receiving
提示:所有的礼物都应立即被寄出去,当然是为了使它们及时被收到。in order to和so as to都表目的,receive和gift之间因是被动关系,所以so as to be received正确。
答案:C
讲评:首先要了解在这里so as to 和in order to是没有区别的。选择的关键在于动词不定式的时态和语态,可以先选择一点入手,然后进行对比。
