选择题
—The rain ________ fast and heavy.
—You should ________ some shelter. Look at you—you are all wet.
A．is coming; find
B．comes; have found
C．came; find
D．came; have found
答案
答案：D
D 考察动词时态和虚拟语气。句义：—这场雨又急又大。—你应当找一个躲雨的地方。你看你，全身都湿透了。根据you are all wet可知，下雨的动作发生在过去，故第一空用一般过去时；根据语境可知，第二空表示与过去事实相反的情况，故用虚拟语气，主语should have done形式。故D正确。
