A.is, was B.is, became
C.was, was D.had been, became
答案应该选A，为什么？请说明原因，谢谢~

因为前面是works,因此是现在经常性或习惯性的动作或状态，符合一般现在是定义，而且陈述一般事实，因此第一个空是is,又因为since后面跟一般过去时，因此是was.而become也可以代替be动词，一般来讲某种职业或---学生前面be动词比较常用写，所以最佳就选a了，明白了吗？再说，如果用过去完成时就表示过去的过去，而这里并不是表示此意，前面动词加了S，为一般现在时，所以D显然不对

这道题比较口语化，意为：Pual在一家动力厂工作，那是在他大学毕业后两个月。也可以将前后位置换一换，翻译更通顺。
是口语句，也表示真正发生了此事，所以用is，since后是过去的事用过去时，再选项里是最佳答案

Paul works in a power plant. It has been two months since he became a college student.
Paul 现在一家供电厂工作。他成为一个大学生已经有两个月了，
（一楼译的不准确）。

有 since 做从句的，它的主句一定是完成时。只有D是完成时。
