Last week, astronauts on the International Space Station had an unwelcome visitor.

上周，国际空间站的宇航员们遭遇了一位不受欢迎的访客。

The best thing though, is to accept a disappointment and then try to use it somehow: Step over the unwelcome visitor on the doorstep and get on with life.

然而，最好还是学会接受失望并学会在某种程度上利用这种负面的情绪：尽早跨越这个不受欢迎的造访者，和生活一起向前走。
