Dear Jenny．

    How is it going? Are you busy with your study these days?

    I've been back at school      nearly four weeks. I am very glad to tell you that great      have taken place in our school this term. First of all, we are aked to "clean our plates" when having our meals and say      to waste. Some of us used to order more than what we could eat. That was a big waste of food and money. Now we need to      the food we order.

    We should also stop wasting in some other ways. For example, we should turn off the lights when we        the classroom. And our school has opened up some     for us to learn how to grow vegetables. Each class is given a small garden and our class has        to grow some tomatoes and beans in our spare time. I think it'll be very interesting. Maybe I'II be able to      you some beans we've grown next time.

    What's more, we have only two classes in the afternoon      we have more time for after-school activities. I am one of the traffic safety volunteers in our school. After school, we take turns asking people in the streets near our school to        the traffic rules.

    I think our school life is now improving! Please write back soon and tell me more about your school.

    Yours truly,

    Wang Wei
