Dear Mr. Smith,

    I'm very much glad to hear that your international shopping center will build non-smoking supermarket. In my opinion, it is a good idea to do so, for it can not only help the smokers to smoke less, and it can also do good to other customers' health. Since you had given up selling cigarettes, the customers who doesn't like smoking are sure to support you. In addition, smoke in the shopping center may cause fire, which is very dangerous to both your possession and the safety of the customers. In a word, the non-smoking supermarket will not effect your business. To the contrary, it will help you attract more customers who want to keep health.

    Best wishes!

    My mom and dad are great cooks, but I always enjoy staying at home and having delicious food. I remembered when I was about six, all the kids in my neighborhood wanted hamburgers and chips, but some didn't have money to buy it. So my father tried to make some on the weekend and asked them eat at my home for the free. The kids were very happier. It helped me make lots of friend. Now I often cooking for my parents, and they like my dishes, either. It's really relaxing to sit around a table for my parents, eating and talking together.

    The teenage year from 13 to 19 were the most difficult time for me. They were also the best and worse years in my life. At the first, I thought I knew everything and could make decisions by yourself. However, my parents didn^'t seem to think such. They always tell me what to do and how to do it. At one time, I even felt my parents couldn't understand me so I hoped I could be freely from them. I showed them I was independent by wear strange clothes. Now I am leaving home to college. At last, I will be on my own, but I still want to have my parents to turn to whenever need help.

    Hello, everyone. It's nice to speak about that we can do for our school, and I think small actions can make big difference. The first thing we can do is to make our campus more beautifully. Every one of them may plant a tree in the school or to organize a thorough cleaning on the campus. We can also form a good habit of putting rubbishes into trashcans. Never forget to turn off the lights and close the doors. We should not leave the tap water run or waste any materials in the laboratory class. In that case, I believe we'll turn our school in a better place to study and live in. How I wish we can enjoy a better school life!

Thank you for listening!
