【写作指导】本篇书面表达是看图写作文，要求考生观察图片并根据所给的提示和要求写出一篇短文。写作内容是我们一直关注的环保问题，首先描述图中一位男士和女士发生的故事，指出城市是我们的家园，呼吁大家一起保护环境！其次写出如果是自己遇到这种情况该怎么做，最后要说明理由。可用到平时积累的建议类句型，如I think...；It’s a good idea...；because引导的原因状语从句等。注意语句通顺，符合英文表达习惯。One possible version:I can see a man and a woman in the picture. The man is throwing litter away, and the woman behind him shouts“Hey! What are you doing Put the rubbish in the dustbin! The city is our home.”I think that lady does a good job. If I see people throwing garbage, I will also do that, because protecting the environment starts from the minor matters. We should do our best to protect our homes. I think it’s a good idea for everyone to take part in environmental protection. In life, there are people who throw rubbish everywhere and do not know how to protect our cities. Therefore, we all have the responsibility to stop others’ uncivilized behavior.

I hope the environment in your city gets better and better.
