M: And what can I do for you？ W: Well, I was thinking about taking a year off after we finish school this summer, and I wanted some advice. M: I see. You mean putting off going to university for a year？ W: Thats right. Ive been offered a place at London University, but what Id really like to do is take a year out first — do something different, maybe go abroad. M: So were you thinking of getting some sort of job, or travelling around？ I mean, is your main aim to earn some money, or to do something else？ Or do you want to do a bit of both？ W: Id really like to travel — but I dont have any money. But Ive heard of an organisation called Peterson International — and thats what I want to ask you about. Do you know anything about it？ M: Sure. Its a charity and its aimed very much at young people like you, and what they do is to get teams of young people to work together on various projects all over the world—environment projects, community projects, that sort of thing. W: Mum, it sounds great. Is it just English people on the projects？ M: No, theyre international teams. Youd be working with quite a variety of people. Questions 13 to 15 are based on the conversation you have just heard. 13. When does Mary want to take a year off？ 14. What projects does Peterson International carry out？ 15.
