高考英语作文：文明礼仪_550字

　　There will be a speech on our school playground this Saturday afternoon, whose theme is “To civilize schoolyard is my responsibility”。 All the teachers and students are required to attend. In the activity, the first two winners in each grade will give such valuable advice as follows: we should not litter anywhere in order to keep our campus clean; we should love flowers, grass and trees so that everyone can enjoy the greenness; we should behave well instead of running after one another, quarreling and fighting noisily; we should care for others so that our school will be full of love. We believe our school will become more and more beautiful and peaceful.
