听力原文：

Long, long ago, there were two men living in the forest. They were brothers. One was called Michael, and the other was called Jack. They never saw the outside world. One day, the older one, Michael, decided to go out to see the outside world. So he packed some clothes and went out. But he found that he had been living in the forest for so long that he didn’t know how to survive outside. Everything, from eating to living, was so hard for him. He almost died. Finally he decided to go back home. When he was back, his younger brother told him, “I know you would be back, because we are so used to life here.” Habits are really powerful; they can even change who you are, so please be stronger than your habits.
