Dear Wang Tao,
    I’m sorry to hear that you have got into the habit of smoking.
    I think it is harmful to themselves and others. It wastes your money and time. As a middle school student, we should study hard instead of smoking.
    Those who have become addicted to cigarettes should be determined to quit smoking. In fact, it’s very easy to get rid of smoking. If you don’t take a cigarette, you’ll feel nervous and stressed. You can take a deep breath and some relaxation exercises.
    If you pay your attention to your study, you will not feel like smoking eventually.
                                                                  Yours,
                                                                  Li Hua
