Mr.Obama and his family will spend the next week on vacation, at the Camp David presidential retreat in Maryland and on the Atlantic resort island of Martha's Vineyard, in Massachusetts.

VOA: standard.2009.08.22

Let's just get them together. Let's get them in a room, whether it was in Camp David,whether it was in Oslo or in Egypt.

我们把他们关到一个房间里吧，无论是在戴维营，奥斯陆或埃及。
