答案：B
I’ve got some information for everyone going to America 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 the 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 are 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 9-5 every day. OK! That’s everything. Have a good trip. 根据短文内容填写下表，每空词数不限：
