I've got some information for everyone going to Britain next month. As you know, you'll be staying

with a family for two weeks. Now the most important thing is money.You should take about ￡30 in

cash (现金) and about ￡200 in travelers cheques (支票). Then when you arrive at tlie airport you'll

be met by our host (主人) family. You must remember to wear a red shirt so the family will find you

easily. I've told them to look out for the red shirts. You'll also need to take with you 4 photos of

yourself and, of course, it's very important that you take the school letter. While you afe there, if you

have any problems, you can call our agent (代理人). I'll give you her office phone number now: It's

580-4436 and the person to ask for is Mrs Belcher, that's B-E-L-C-H- E-R. She's in the office from

9:00 t0 5:00 every day. OK! That's everything. Have a good trip.
