The summer vacation is the best part of the year for most American chil-

dren. The weather is usually good, so they can have a good time outdoors. If one

lives in the countryside , he or she may have fun playing in the woods or fields .

If one lives in a big city, he or she likes to go to a park to play.

Tom, an American boy, enjoys traveling very much. He always travels in

his country. This summer he wants to do something different. He is interested

in Chinese history. So he is going to Beijing and Xi'an by plane. He is leaving

on the 15th of July and getting back to New York on the last day of the month.

He plans to have a fantastic vacation. During the day, he is visiting places of

interest and going shopping. At night, he is taking walks to enjoy night views.

He's sure he'll have a wonderful vacation.
