The summer vacation is the best part of the year for most American children. Before the summer vacation comes, they make a plan to       they have a good trip.
Tom, an American boy, enjoys traveling very much. This summer, he came along       his parents to Beijing     their vacation. They made room reservations（房间预订） before they        . After arriving, they spent half a day in the hotel to       the time difference（时差）. Tom was       excited to fall asleep that night. The next day, they began their     trip. They visited many places of interest     the Ming Tombs, the Great Wall and so on. They couldn’t help      photos all the time. During the trip, he posted a lot of postcards to his American friends. In the postcards he told them that he was satisfied with (对…很满意) the trip and he was looking forward to      to China again.
What an exciting trip!
