Dear Wei Lin:
      It was really good to hear from you again, but I was surprised to learn that you started smoking soon
after you went to the U.S. You said that smoking helps you relax. This might be true, but there are better
ways to relax . And doctors tell us that smoking can only help us relax for a short time.
      I remember when you were in Taiwan, you were afraid that the air pollution might harm (对...有害处)
your health. But don't you think you're also harming your health when you smoke?
      Smoking can hurt other people's health, too. And I've heard that some people have gotten cancer from
second-hand smoke. So for your own health and for the health of others, please give up smoking …
                                                                                                                                                 Yours,
                                                                                                                                                 Alex
