How to say the following phrase in Mandarin? I'm preparing a presentation for my Mandarin class. The idea is to stage a situation. Basically the point is to create a situation which begins with a Chinese person asking for two foreigners to take a picture for him. Since the situation is to happen in China, this seems very unrealistic, so I decided to start the stage with the Chinese person talking to himself:


  I'd like to take a picture of me and my family, but there is no one around except those two foreigners. I will ask them.


How do I say that in Mandarin?
"I'd like to take a picture of me and my family, but there is no one around execpt those two foreigners. I will ask them."

我想找人帮我们拍一张全家福，但周围除了两个外国人就没有别人了。我去问问他们。
