解题思路： 解答如下
解题过程：
But for the fact that China ___ also affected by the global economic crisis, we ___ fewer unemployed workers now.
虚拟语气中，一些特殊的连词暗含假设、虚拟，比如but, otherwise=or, but for the fact that, without.
本句But for意为“要不是”，the fact是个现在事实，所以要用一般现在时is，对现在的虚拟，主语结果（now）要用would do,所以选A。
如果the fact是个过去事实的话，要用一般过去时。虚拟的结果（主句）如果是现在的，就变成错综虚拟语气了，要用would do；虚拟的结果如果是过去的，就用would have done.
比较这两个句子：
But for the fact that he was ill, we would invite him to join us now.
But for the fact that he was ill, we would have invited him to join us yesterday.
希望满意，欢迎讨论。
最终答案：略
