1．(·镇江期末调研)—What do you think of the American singer Lady Gaga’s performance?
—Too crazy, but if she ________ come to China to hold concerts, I would buy tickets for her live show.
A．would B．could
C．should D．might
解析：选C。由句意和语境可知，此处考查与将来事实相反的虚拟结构。表示与将来事实相反的虚拟语气条件句的谓语动词用“过去式”或“were to＋动词原形”或“should＋动词原形”，故选C。
2．(2012·豫南九校联考)But for the fact that China ________ also affected by the global economic crisis，we ________ fewer unemployed workers now.
A．is；would have
B．were；would have
C．was；would have had
D．were；would have had
解析：选A。第一空为同位语从句中的谓语，主语为China，谓语动词用单数，排除B、D；由but for可知，第二空用虚拟语气，由时间状语now可知，此处表示与现在事实相反的假设，所以选A。
