Tom enjoyed going to the movies. He especially liked seeing movies made from stories he had read in the books. He went at least once a week. He liked to sit in the same seat, but sometimes when the theater was full, this was not possible. He had to sit wherever there was an empty seat. One evening, he found himself sitting behind a man who had his arm around a large dog on the seat beside him. This was strange, but even stranger was the dog’s behaviour(举止，行为). It seemed to be watching the movie with interest, but from time to time it would turn to the man and bark quietly in his ear. The man would just nod, and the dog would turn back to watch the movie. Sometimes when something funny happened in the movie, the clog barked quite loudly and wagged(摆动) its tail. Tom sat behind the man and his dog for a long time without saying anything. He thought it would be rude to speak to them while the movie was still on. But when it came to the end and the lights in the theater went on, Tom decided to say something.

He hated the film.\ Tom enjoyed going to the movies. He liked to sit ______.
