    Hello, children and parents. 
    Thank you all for coming to this meeting. I'd like to start by confirming (证实) that we will receive some
money from the government for our school trip to Indonesia. We will receive about $1,300 per child, and it will
reduce the overall (全部) cost to you.
     Now that we are sure to get the money, it is time to do some serious planning. We are sure that the trip will
be very exciting for the children, especially if they have not traveled abroad before. There are many advantages
of having some experiences to different places and cultures. Your children will be able to learn a lot about other
people and cultures on this trip. Leanne is with us tonight.
    Leanne, where are you? Put up your hand so that the people can see who you are. Thank you. Leanne went
on a trip there with some other students last year and will be happy to tell you of her experiences and answer
any questions you might have. We will hear from her a bit later in the meeting.
    We only have five months to organize the trip. From past experience I can tell you that this time will go very
quickly! So we need to start organizing the trip.

This is the agenda (议程) for this evening's meeting:
Passports: when and how to apply for (申请) one
Health matters: what precautions (预防) you need to take, plus any special needs that your child may have 
Studying: what kind of the school and type of lessons your child will attend 
Money: paying for the trip, plus how much money your child should take 
Hotel: where we will be staying Clothing and personal items that your children should take with them
