Dear Jenny, How’s it going? Are you busy with your study these days? I’ve been back at school 1 nearly four weeks. I am very glad to tell you that great 2 have taken place in our school this term. First of all, we’re asked to “clear our plates（餐盘）” when having our meals and say 3 to wasting. Some of us used to order more than what we could eat. That was a big waste of food. Now we need to __4 the food we order. We should also stop wasting in some other ways. For example, we should turn off the lights when we 5 the classroom. And our school has opened up （开辟） some fields for us to learn how to grow vegetables. Each class is given a small garden and our class has decided to grow some tomatoes and beans（豆类）in our 6 time. I think that’ll be very interesting. Maybe I will be able to 7 you some beans we’ve grown by ourselves next time! What’s more, we have only two classes in the afternoon 8 we have more time for after-school activities. I’m one of the traffic safety（交通安全） volunteers in our school. After school, we take turns to go to the streets near school and ask people to __9 the traffic rules. I think we are having a different school life now! Please write back soon and tell 10 more about your school. Yours, Wang Wei
