Boys and girls,
    May I have your attention, please? About sixty Australian students will come to visit our school on June 15。
   We’ll meet them at the school gate at 8:30。 We’ll take them to the meeting-room, where a get-together will be held。 After that, we’ll show them around our botanical garden and the school-run factory。
   At11:00 there will be a basketball match on the playground。 They’ll leave our school at 12:00。
    Please be friendly to them。
   We must talk with them in English。
　　That’s all。 Thank you。
。
