I'm Li Hua from Class 5. 　　What can people and nature give each other? Saihanba has the answer. Half a century ago, it was a wasteland buried in sand. Then, in 1962, the first foresters arrived and planted their first saplings in wind and snow. 　　Three generations spent fifty-five years turning the bare land into a sea of forest. Today, that forest holds back the sandstorms pushing south, feeds rivers, and shelters birds that had long been gone. What the foresters planted were trees; what they harvested was reconciliation with nature. 　　Their story tells us that nature never lets down those who respect her. So let us start small—save paper, plant a tree, refuse one plastic bag. To nurture nature is to nurture ourselves. Thank you for listening! 【学生习作】 Good afternoon, everyone. I'm Li Hua from Class 5. 　　Today I want to talk about protecting nature. Nature is very important to us. It gives us air, water and food. But now there is much pollution. Many forests are gone. 　　Saihanba is a good example. People planted many trees there for many years. Now it is a big forest. It is very beautiful. 　　We should protect the environment. We should not throw rubbish. Let us plant more trees and make the earth green. Everyone should do something.

It's a great honour to speak here. 　　Last spring, our class spent a whole Saturday by the river near our town.

That was when I truly understood: nature answers every effort we make, only a little more generously than we expect. 　　So let us start small—save a sheet of paper, plant a sapling, refuse a plastic bag.

Many forests are gone. 　　Saihanba is a good example. People planted many trees there for many years. Now it is a big forest. It is very beautiful. 　　We should protect the environment. We should not throw rubbish. Let us plant more trees and make the earth green. Everyone should do something. Thank you for listening! 【习作点评】 优点：观点正确，有塞罕坝的例子，格式完整，问候与致谢都有，态度积极。 问题一：案例只有"People planted many trees there for many years"一句，太笼统；应写出关键数字——三代人、五十五年、从荒原到百万亩林海，以及"挡住南侵风沙"的今昔对比。 问题二：感受与案例脱节，"Nature is very important"是常识不是感悟；应从案例中提炼，如"种下的是树，收获的是与自然的和解"。 问题三：句式全是简单句，没有一个倒装或强调句；Only by living in harmony with nature can we have a future 这类本单元句式应至少用一次。 问题四：倡议只有"不要扔垃圾"，太空泛；应给出具体可做的小事，并落到金句"To nurture nature is to nurture ourselves."。 【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：案例要"今昔对照"。先写"黄沙漫天的荒原"，再写"百万亩林海"，中间用三代人五十五年衔接，反差越大，说服力越强。 得分点二：感受要"从树里长出来"。由"种树"引出"人与自然相互成就"，一句话完成升华（What they planted were trees; what they harvested was reconciliation with nature.）。 得分点三：本单元词块要用够。transform...into...、devote one's life to、in harmony with nature、hold back、benefit from 至少出现四个；结尾用"To nurture nature is to nurture ourselves."收束，立意即题目。 学科网（北京）股份有限公司 $
