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．is; would have had
答案：A
题目分析：考查虚拟语气。本题是一个含蓄的条件句的，其条件是通过介词短语but for转换而来；根据主句后面的Now说明是与现在的事实相反，故使用“情态动词+动词原形“构成；第一空使用陈述语气。句意：如果不是中国也受到全球经济危机的影响，我们就会有更低的失业率。故A正确。
点评：本题中的but for=without要不是，如果没有…；引导虚拟语气。虚拟语气是高考每年的必考点，用法较多，平时学习应积累巩固。
