      I will be traveling to Australia as a Student Ambassador with People to People. People

to People arranges for American students to travel all around the world to learn about other

cultures, and to help others understand American culture. The program was founded by

former President Dwight D. Eisenhower to promote peace through understanding.

     I had to put in many hours of special work to get to this point. First, a teacher nominated

(推荐) me, and then I attended an informational meeting about the program. The application

process included an interview, and finally, I was accepted.

     That's when the hard work really began. In addition to attending monthly meetings to

prepare for the big trip, my parents encouraged my twin sister Beth (also participating in

the program) and me to raise $ 2,000 each to help pay for the cost. And so the fund-raising

began. We did everything from selling candy bars to selling an old car to decorating people's

mailboxes during the holiday season. We also babysat, washed cars, held a yard sale, and

washed windows. After months of hard work I had raised a total of $2319.87! Combined,

Beth and I raised over $ 4500.00!

     Now I have a problem-packing. Yes, I know it sounds unimportant, but my suitcase

seems to have shrunk (收缩) as I placed my belongings inside. According to airline

regulations (规定), a suitcase can be no larger than 54 inches and weigh no more than 44

pounds. For a person who likes to wear a different outfit every day, packing all my clothes

into such a small space seemed an impossible task. However, I have lessened my load and

my suitcase which started out weighting overweight now checks in at a mere 36. Apart from

a slightly bloated (臃肿) carry-on bag, my luggage is definitely manageable.

     I doubt that I will not get much sleep tonight because I am so excited! I know that what

lies ahead is going to be the trip of lifetime!
