Jane: You don’t look very cheerful. What’s the matter, Jack? Jack: Oh, nothing special, Jane. I’m just a bit fed up. Jane: With your job? Aren’t you satisfied with your present work? Jack: No, I’m under a lot of pressure at work. My boss always wants me to increase sales. Sometimes the sales goal is almost impossible to achieve. I’m not pleased with it. Jane: I used to feel stressed out like you but I managed to find some time to jog every morning. It did work. Jack: Maybe I should try it. But you know, I am very busy. The work here is really tiring. Jane: Cheer up! Maybe being busy means there are more opportunities for a promotion. Jack: I hope so. But Miss Green, my boss, enjoys picking on me. I really can’t stand it. Jane: Stop dwelling on it. Think about the positive side of your work and you will feel better then. (1)Why does Jack look not vey cheerful?
