Dear friends, Do you want to live in a beautiful world? So it is our obligation to maintain the ecological balance. To fulfill this task, we should bear the following ecological codes in mind. First, while sticking to the habit of walking to school, we should eat at least five kinds of fruits and vegetables a day. It’s also important to recycle everything recyclable and cherish our school’s environment by picking up any litter and turning off the taps and the lights. Let’s all take action now and contribute to the prosperity of our mother—the earth. Thank you!

Dear Editor, I’m writing to tell you about the discussion we held on whether it is good to keep animals in zoos.
According to a recent survey, about 25 percent of college students have part-time jobs. During summer vacation, this figure will increase to 72 percent. College students are working as tutors, waiters or salesmen.
Why do they want part-time jobs? First, they want to earn a little money to help cover the increasingly higher college tuition. Second, they hope to be economically independent and buy whatevr they want. By doing part-time jobs, college students can gain some society experience and broaden their outlook. What is more, part-time jobs can provide them with a valuable chance/ opportunity to know the out side world. 3 假如你是张华， 近日写信给某英文报的编辑，反映目前人们滥养宠物的问题，希望得到媒体的关注和支持。信的内容应包括以下要点： 1.宠物过多，噪音扰民； 2. 污染环境； 3. 不少人尤其孩子曾被惊吓或咬伤；4. 传播疾病。 注意：1.词数100左右; 2.信的开头和署名已为你写好，不计入总词数。
