Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 31 to 35.

  When you wake up in the morning, do you assume that you're going to have a great day or that you're going to have a difficult day? If you normally have positive expectations, you might consider yourself an optimist, and if your expectations are usually negative, you may be a pessimist. According to research done by the Mayo Clinic, optimism can have a strong positive effect on your health. Their research shows that optimists may live longer, get colds less often, and be less likely to suffer from cardiovascular disease. Optimists may even deal with stress better than pessimists do. If you think you might be a pessimist and would like to try to be more optimistic, pay attention to what some call “self-talk.” The term “self-talk” refers to the automatic thoughts that go through your head all the time. You know-the ideas, worries, beliefs, and hopes that run through your mind as you're driving, washing dishes, folding laundry. Are those thoughts negative like, “Everyone knows so much more than I do,” or positive like, “I'm learning a lot at this job”? If your self-talk is negative, there are some things you can do to steer it in a more positive direction. First, you can simply stop your negative self-talk. Every time you catch yourself thinking something negative, you can stop yourself by actually saying, “Stop,” out loud. Alternatively, you can revise your self-talk. For example, if you catch yourself saying, “I’m terrible at giving presentations,” revise that to a question like, “How can I improve my presentation skills?” Another idea is to think of yourself as a friend. When you “hear” a negative sentence go through your mind, think about whether or not you would feel comfortable saying it to a friend. If the sentence seems too mean to say to a friend, think about what would sound better. (Adapted from Select Readings by Linda Lee and Jean Bernard)
