Dear Jenny, How’s it going? Are you busy with your study these days? I’ve been back at school 41 nearly four weeks. I’m very glad to tell you that great 42 have taken place in our school this term. First of all, we’re asked to “clear our plates” when having our meals and say 43 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 44 the food we order. We should also stop wasting in some other ways. For example, we should turn off the lights when we 45 the classroom. And our school has opened up 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 46 time. I think that’ll be very interesting. Maybe I’ll be able to 47 you some beans we’ve grown by ourselves next time! What’s more, we have only two classes in the afternoon 48 we have more time for after-school activities. I’m one of the traffic safety volunteers in our school. After school, we take turns to go to the streets near our school and ask people to 49 the traffic rules. I think we are having a different school life now! Please write back soon and tell 50 more about your school. Yours, Wang Wei
