Reduce is using less. For example, if you go to a restaurant , order what you can eat. Second, reuse. Reusing is using again. The clothes and the toys can be given away to others babies if your child has grown older. You dont have to buy trendy clothes because it is just a waste of money. Third, recycle. Recycling is making new things from the old things. There are lots of things which can be recycled in our daily life., such as paper, cans, and plastic bags. So it is necessary for us to sort the garbage out. If we follow the 3Rs, well save more natural resources. Dear friends, lets take action to do it from little things!

Thank you!Thank you!Thank you!Thank you! 一、整体设计思路、体现的理念 本堂课是一堂作文讲评课，在课前教师布置了一篇写作，整堂课就是以这篇学生作 文为基本的文本载体来开展的。本堂课的主要思路是让学生转变身份成为作文的批阅 者，在教师的引导下知道如何批阅作文，如何改进作文。本堂课主要体现了课堂教学 以学生为本的基本理念，要求学生站在教师的角度是审视作文，让学生能明白以后应 从什么地方来改进作文。对于学生思维品质的培养，这种转换身份的教学方式能促成 学生形成系统的作文评价理念，能帮助学生更好掌握写作方法和技巧。 二、教学背景 1、教学内容分析 本课是一堂初三下学期的写作讲评课，教师在教完 13 单元之后对课后的写作话题 进行了适当的改编，因为 13 单元的话题是写作训练中最常出现的环保题材，所以笔者 选择这个单元的作文作为文本载体对于其他观课教师来说是有实际的可操作性的。到 了初三这个时候学生的写作水平已经基本定型，但是如果教师加以引导仍然有很大的 提升空间。特别是对于考场作文来讲，如果学生能熟知并掌握很多的写作技巧，对于 学生写作水平的提高是大有裨益的。本堂课教师没有选择写作范文去让学生分析和临 摹，而是选择了让学生以自己的文本为载体进行分析和再创作，这样的教学内容更容 易让学生接受，更容易激起学生的兴趣，更容易让学生在课后获得满足感。 2、学生情况的分析 对象：重庆实验外国语学校初三学生 特点：大部分学生备考心理基本成熟，求知欲极高，对于学法指导的课堂兴趣浓厚。 基础：学生具备一定的写作基础，但是一个班学生的写作水平参差不齐，部分学生对 于写作要点的把握不到位，部分学生缺乏一定的写作技巧，大多数学生对于如何改进 自己的写作感到困惑。 三、教学目标 1. 语言能力目标： 1）掌握中考作文的基本评分要求。 2）学生能运用评分要求改进自己的作文。 2. 学习能力目标： 1）通过学习对自己和他人的作文进行合理测评。 2）学生能形成基本的写作思路，并形成如何创造优秀作文的思维导图。 3. 思维品质目标： 1）学生学会独立思考、自主学习。 2）学生能在小组活动中分工合作，互帮互助。 3）学生能换位思考，积极研究。 4. 文化意识目标： 1) 学生能自主自理，自我完善。 2）学生在活动中发展合作、互助的情感价值观。 3）学生能体验自主学习、自主评价的快乐，激发学生独立思考的兴趣。 四、教学重、难点 1. 教学重点： Find the grammatical mistakes in a composition and correct them. Better the words and sentence patterns in a composition. 2. 教学难点： Differentiate different kinds of mistakes. Make the simple sentences into complex ones. 五、教学过程设计（方法、手段、意图） Procedures ActivitiesPurposes Ask the students to take out the compositions , and review the requirements of the composition. Ask the students to circle the key words in the requirements to help them realize what they should write in their composition. 帮助学生预热本堂课要使 用的文本信息。帮助学生 勾出写作信息中的关键词， 帮助学生理性审题。 Step 1: Lead in Tell the students what we should do today:1.Work with your group members to mark one of the compositions in a group. 2.Better your composition and make it worth a high score. 明确提出本堂课学生要完 成的任务，让学生从心理 上做好准备，对整堂课的 内容有一个整体的把握。 Step 2: Show the criteria of judging a good composition Show the criteria on the PPT and tell them how many points each aspect is worth. 让学生对作文的评价标准 有一个整体的把握并能有 意识的区分每个板块在评 价标准中所占的比重。 Step 3: Handwriting part T: Good handwriting gives people a good impression. Then show the students how many points some examples from the test papers get because of their handwriting. Make the students understand how important the handwriting will be when judging a composition. T:The handwriting is like the cover of a book. If a book has 通过给学生展示 2015 中考 考场上的真实作文和它们 的得分，让学生对书写的 重要性有一个更直观的印 象。 a beautiful cover, it makes people have the desire to read it. Step 4: Layout and the beginning and the ending part Show the students two compositions with the same context but different layouts. Tell the students that it is clearer to arrange your composition into three paragraphs. T: Then lets see how to give a good beginning. First, we have to raise a problem. Look at the first sentence. Sometimes we use questions to start a passage. Sometimes we begin the passage with a description of a picture which gives people a strong feeling. So could you tell me why they are good ways to give a beginning? S: To attract the readers attention. T : Yes. A good beginning attracts the readers attention, and makes them want to read the rest of your passage. T: Then how to give a good ending? First, youd better coordinate with the beginning. We can use other sentence patterns to stress the things which have been mentioned before. And then make a proposal to call for people to do something or pay attention to something. 呈现两遍结构不同的作文 让学生自己去判断哪一篇 的结构更加清晰一些。接 下来对于文章开头结尾的 分析能让学生遵循到一定 的写作技巧，对于中等学 生或是差生更加体现出积 极地引导作用。 Step four : Grammar part Show the students five kinds of common mistakes. Ask them to take notes , because students can recall these categories when they are doing exercises. Give the students a short paragraph and then ask them to find all the grammatical mistakes from the beginning to the end. The students have to point out the mistakes and then correct them immediately 帮助学生区分作文中常见 的语法错误，并让学生自 己尝试去辨识，通过小组 活动的形式能激发学生回 答问题的动力。 and them tell others what kind of mistake it is. The teacher arranges this part into a group work to motivate the students to answer questions. Step five: Words and sentence patterns part T: Sometimes a composition which has no mistakes can not be called a good composition because it doesnt have good words or good sentence patterns. Better words and sentence patterns can make the writing more vivid and meaningful. As for this part, there are two aspects you have to pay attention to. 1. Better the words. 2. Better the sentence patterns. T:As for words: a. Wonderful phrases can be used instead of common words. (Give students an example):It can make us understand the world, and it can make us feel relaxed. Lets see the red word “understand” we can use a phrase to replace it.-have a better understanding. You can see they have similar meanings, but the phrase has a stronger power to make the sentence more vivid. Next give the students more sentences to practise. T: As for words:b.More suitable words can also be used according to the context. (Give the students an example)You cant make noise or put rubbish on the ground. Put is a common word, but its not appropriate to use “put” here, we can change it into throw or drop. Next give the students more sentences to practice. T: As for the sentence patterns:Simple sentences can be put into complex sentences for better.(Give the students an example) There are many good suggestions from my 这个词汇与句型部分充分 发挥了讲练结合的原理， 教师先举例说明，学生通 过后面的练习加以理解和 巩固，让学生在有限的课 堂时间里充分的理解并掌 握知识点。 readers. I dont know which one to choose. Ask the students to combine the two sentences together. S: There are so many good suggestions from my readers that I dont know which one to choose. Then give the students more sentences to practice. Step Six:Logic partAs for the logic: Show the students some words and phrases which can be used to make the composition more logic. Ask the students to find them in the composition and circle them. 显示文章逻辑的连接词部 分在平时的写作教学中就 不断的有提及，所以在这 里就是一个简单的总结概 括。 Step Seven： Summary T：Ask the students to give a total score to the composition. And then help the students to review how to mark and better a composition. Ask the students say aloud the five parts one by one. 在课堂的结尾处让学生回 顾本课所学是一个非常有 效的教学方法，学生通过 回顾和总结所学内容能帮 助他们加深印象。 Step Eight：Homework T: Ask the students to better their own composition according to what they have learned today. 这个环节如果能在课堂上 做，并把学生改后的作文 用投影的方式呈现出来就 更好了，但是由于一堂课 时间的限制，这个环节只 能留到课后去处理。 六、教学评价 1. 学生回答问题，教师的口头评价。 2. 小组评价。 根据小组成员举手发言的情况来加分，最后算出小组的总得分。 七、板书设计 Criteria Group points: 1 2 3 4 5 八、反思 笔者认为，本节课的成功之处有以下几点：1.在教学过程中，笔者以学生自己的文章 为文本载体并结合小组合作互换作文的方式，让学生充当教师来评价别人的作文，并 通过小组活动鼓励和引导学生积极发言。 这样的教学设计能激发起学生的兴趣，有别 于通常意义下枯燥的作文讲评课。 2. 对于初三复习阶段，学生其实欠缺的不是大量的练习而是有效的学法指导课，这样 的课能帮助学生搭建如何写好作文的基本框架，对于学生形成正确的写作思路并对于 以后的作文如何改进有很强的指导意义。 3.整堂课没有很花哨的游戏环节，但是学生的思维应该是时时刻刻活跃起来的，学生 需要在专注的情形下紧跟教师的步伐，在每一个教学环节，教师都会让大部分学生甚 至是所有学生都参与进来。所以这堂课看似平稳，其实学生的思维节奏很快，强度比 较大。 本节课还有一些需要改进之处： 1.时间分配需要更合理。在找出同学中的语法错误部分，学生的个别指导超出了预计 的时间使得后面的改进单词和句型部分有点匆忙。 2.由于课堂容量的关系，如果能在第二节课中让学生通过学到的方法改进自己的作文 就更能体现学生的输出效果，但是这样的输出如果没有前面足够的输入也是不可能实 现的，所以这样的作文复习课型还有待进一步的打磨和专研。 s Handwriting 4 Layout and beginning, ending 3: questions or good sentences Grammar 4: five types of grammar mistakes Words and sentences 5 Logic 2
