Thank you for your invitation to the press conference on April 29, 20xx, but we regret that we can not accept it. We are now short of hands because the majority of our staff was set over the reports of the Japanese earthquake.

感谢你们邀请我们参加20xx年4月29日举办的新闻发布会，但是我们很遗憾不能接受邀请。 我们绝大多数的人员都被派往日本报道地震情况，因此我们的人手很紧张。
