书面表达。（10分）某英文网站提出“走路去上学”的倡议，请你就这一话题写一篇约80词的英语文章。内容包括：走路有利健康，

I think going to school on foot is good for us. First of all, walking to school is a wonderful way to exercise and it’s good for our health. Next, it’s fun to walk together with friends every day. We can talk about something interesting and know each other better. What’s more, if we walk, our parents won’t have to drive us to school. There will be fewer cars in the city. More walking and less driving help to make our city cleaner. The streets won’t be as crowded as they are now. I hope more and more students will go to school on foot.
