I'm Li Hua from Class 3. 　　The environment is not a topic far away from us. It is the air we breathe at seven in the morning and the water we boil for noodles at noon. 　　Yet look around: plastic cups pile up beside the water dispenser, lights burn in empty classrooms, and half-finished rice slides into the bin. None of it feels like much—until you multiply it by two thousand students and three hundred days. 　　So let us start with three small habits: carry a bottle, finish your plate, and switch off what nobody is using. None of them costs money; all of them cost attention. 　　The earth does not need a few heroes. It needs two thousand ordinary people doing small things. Thank you. 【亮点句式】 ① It is the air we breathe at seven in the morning…（把“环境”落到可感的日常细节） ② None of it feels like much—until you multiply it by two thousand students.（数学式论证，一句顶十句空话） ③ None of them costs money; all of them cost attention.（对称句 + 分号，节奏鲜明） ④ The earth does not need a few heroes. It needs two thousand ordinary people doing small things.（短句收尾，回扣演讲场合） 八、范文赏析 【参考范文】 Good morning, everyone. I'm Li Hua from Class 3. 　　Last Monday I walked past the bins behind the canteen: three bags of untouched rice, still warm, and a tap running unattended. 　　A green campus is not built on slogans but on small decisions. Finish what is on your plate, carry a bottle, and be the last to switch off the light. 　　Our school throws away 200 kilograms of food a day. Ten grams less from each of us would save twenty kilos—every day. 　　The earth does not need a few people doing everything perfectly. It needs all of us doing small things. So tomorrow: bring your bottle, clean your plate, turn off the tap. Green campus, green future—it starts now. Thank you! 【学生习作】 Good morning, everyone. I'm Li Hua from Class 3. 　　Today my topic is green campus. The environment is very important for us. But there are many problems in our school. Some students waste food. Some students use plastic bags. Some students forget to turn off the lights. 　　Firstly, we should save food. Secondly, we should use fewer plastic bags. Last but not least, we should turn off the lights when we leave. 　　Let's take action together. If everyone does something, our school will be better and better. Thank you! 【习作点评】 优点：结构完整，问候与致谢齐全；三个要点都有涉及，提出的三条建议方向正确，结尾有呼吁，语法错误很少，作为基础稿是合格的。 问题一：开头“The environment is very important for us”是万能句，任何题目都能用，等于没有扣题。应换成校园里的一个具体场景，如“食堂后三个装满剩饭的袋子还冒着热气”。 问题二：问题与建议一一对应成“Firstly / Secondly / Last but not least”的清单，没有一句展开，读者不知道浪费有多严重。应补一个数字（一天两百公斤）或一个细节（水龙头没人关）。 问题三：句式全部是“Some students... / We should...”的主谓宾短句，节奏平板。可加入分词状语（Walking past the bins, I saw...）、强调句或 not...but... 结构。 问题四：结尾“our school will be better and better”空洞，且与前文的“具体建议”脱节。应回到动作：“明天早上，带上你的水杯，吃干净盘里的饭，关掉那个还在流的水龙头。” 【评分标准】（满分15分，按高考应用文评分细则） 档次 分数 评分描述 第五档 13—15分 覆盖全部要点，应用了较多语法结构和词汇，句式有变化，衔接自然，语法和拼写错误极少，完全达到交际目的。 第四档 10—12分 覆盖全部要点，语法结构和词汇能满足任务要求，衔接基本连贯，有少量错误但不影响理解。 第三档 7—9分 基本覆盖要点，语法结构单调，词汇有限，有一些错误，部分内容表达不清。 第二档 4—6分 遗漏较多要点，语法结构单调、词汇项目有限，错误较多，影响理解。 第一档 1—3分 只能写出个别单词，内容太少，无法传达信息。 【写作指导：本单元写作的三个得分点】 得分点一：把“环境”缩小到“校园的一平方米”。阅卷老师看了一百篇“the earth is in danger”，你写“食堂后的三个垃圾桶”，立刻就有了辨识度。 得分点二：用一个数字代替十个形容词。“200 kilograms a day”比“a serious waste”有力，“ten grams less each”又让听众知道自己能做什么，一进一出，论证就闭环了。 得分点三：演讲稿要有“声音”。用设问开头（Is this the campus we want?），用祈使句推进（Bring your bottle. Clean your plate.），用短句收尾，让文字一读出来就有节奏。 学科网（北京）股份有限公司 $ 选择性必修三 Unit 3　Environmental Protection 单元写作作业 一、单元写作任务 假定你是李华，6月5日世界环境日，你校将举办以“Green Campus, Green Future”为主题的英语演讲比赛。请你写一篇演讲稿参赛，内容包括： 1. 描述校园中存在的两三个环境问题； 2. 提出两条具体可行的行动建议； 3. 呼吁全校同学从今天做起，共同守护校园。 注意：1. 词数100左右；2. 可适当增加细节，以使行文连贯；3. 开头和结尾已给出，不计入总词数。 Good morning, everyone.

I'm Li Hua from Class 3. 　　The environment is not a topic far away from us. It is the air we breathe at seven in the morning and the water we boil for noodles at noon. 　　Yet look around: plastic cups pile up beside the water dispenser, lights burn in empty classrooms, and half-finished rice slides into the bin. None of it feels like much—until you multiply it by two thousand students and three hundred days. 　　So let us start with three small habits: carry a bottle, finish your plate, and switch off what nobody is using. None of them costs money; all of them cost attention. 　　The earth does not need a few heroes. It needs two thousand ordinary people doing small things. Thank you. 学科网（北京）股份有限公司 $
