个人觉得第一个空加个a好点吧,director of the Chinese Earthquake Research Center这不是一句完整的话,只是用来修饰Chen jianmin 起说明作用的成份,这个结构也就是一个同位语结构,如果说不加a的话,那么这里的director就是一个官衔或者职位,这种情况就不加a.

1) 国名,人名前通常不用定冠词:England,Mary;

第二个用an你没有问题吧?!
问题应该是前面那个空为什么不填!
不填的原因是:director of the Chinese Earthquake Research Center这不是一句完整的话,只是用来修饰Chen jianmin 起说明作用的成份。
这也是英语的习惯表达,非要问个为什么的话,真的不好弄。碰到多了,你就明白了!...
