听力原文： Hollywood produces many different kinds of films, including mysteries, musicals, love stories, and horror films. As different as these films may be, they generally have one thing in common conflict. The main character wants something very badly and will do anything to get it. The opponent tries to stop the main character from achieving his goal. This opposition creates conflict, and conflict is the heart of drama. To give an example, let's say the main character is a young man of humble origin who wants to marry the beautiful daughter of a rich banker. The father thinks the young man is unworthy of his daughter, and he does not allow her to see him. The young man, who's very much in love, refuses to give up without a fight. The conflict between the young man and the girl's father is what makes the story interesting; it forces the main character to take action, and through their actions we see them as they actually are. In a good story, the main character changes he is not the same at the end of the story as he was at the beginning. He learns something from his experiences that make him a different, perhaps batter person. And we learn something from watching him. Good movies not only entertain us, they also help us understand a little more about life.
