Unit4 写作课名师教学设计Module 6 Unit 4 Using Language--Writing教学设计1. 学情分析Learning situation:In BOOK6 UNIT4, although students have already learned some knowledge about global warming in the previous reading part, they still have some difficulties in expressing ideas on how to reduce global warming in their daily life. Besides, for the writing task, students have known something about how to write a letter of advice, but most of them still don’t know the structure of it clearly, which may cause some confusion in their writing. So they need more guidance and some proper help on how to give suggestions on such big a social problem--how to reduce global warming.2 重点难点Difficult points and important points:Students may have difficulty analyzing which key information should be included in the letter and how to make use of some good sentence-patterns of suggestions. So students may have difficulty using their own words for the output part.3 教学过程3.1 第一学时3.1.1教学目标Teaching goals:1. Language competences: Students will be able to(1)learn some new words in situations: global warming, carbon dioxide, the rise of the sea level, cause, make a difference, count.(2)learn the structure of a letter of advice.(3)learn how to express themselves by using proper sentence-patterns of suggestions.2. Learning competence:The class is based on the students-centered principle, so every student is encouraged to participate in all the steps of writing. The teacher is just a guide, who will adopt some skills to get students to think about one question in the whole class---how canwe write a letter of advice on a social problem well? After all these activities, students will be able to exchange their ideas and learn how to organize a letter of advice.3. Cognitive competence:Students will be able to think about the structure of this kind of letter critically and they will form a right attitude towards the problem of global warming, which will exert some positive effects in their daily life.4.1.2 学时重点与难点Difficult points and important points:Students may have difficulty in analyzing the key information before writing and failing to adopt some good ways to express their opinions.4.1.3 教学活动活动1【导入】Greetings＆Lead inEnjoy a short video1. What is the video about? Global warming2. What are the main causes of global warming?It is human activities that have caused global warming, for example, human beings are putting too much carbon dioxide into the air and many people are still cutting down trees in the forests.As we have seen in this video, global warming has caused many disasters in the world. It has become so serious a problem that many people around the world are concerned about it. Are you concerned about it? What can we do to help? We may do some small things to call on more people to take action, for example, we can finish a task like this.【设计说明】: 在Greetings的环节明确本节课教学目标，本节课我们要学习写一封信。

在leading in环节中, 通过观看一个短视频，学生了解到Global warming 会带来很多自然灾害并严重影响人们的生活，是一个严重的社会问题，引起了全世界人民的关注。

那么，作为青少年，我们能做些什么事情来减缓全球变暖这一问题呢？本活动旨在整合已学知识，激发学生关注全球变暖这一个严峻的问题,激发学生对该话题的兴趣。

活动2【活动】Exploring the Writing Task随着经济的发展，更多的温室气体被排放，其中大约70%为二氧化碳，这也是全球变暖的主要原因之一。

全球变暖造成海平面上升和自然灾害频繁发生，引起了全世界人民的广泛关注。

Earth Care组织正在向我校的学生征求减缓全球变暖的建议，请你用英语写一封建议信。

注意：词数80-100字左右，可适当增加细节，行要规范。

审题：⑴判断文体⑵判断时态和人称⑶判断要点【设计说明】:1.引导学生关注写作前审题的重要性。

2. 审题主要包括三个方面：第一这是一封建议信，而且是写Earth Care组织的；第二该信应该用第一或者第三人称，不能用第二人称，时态应该用一般现在时；第三，找到key points，包括问题、影响和建议。

这些问题的答案都是学生自己经过思考之后得出的结论，不仅为接下来的写作做了很好的铺垫，而且传递给学生这样的信息：写作前审题的步骤是非常关键的。

活动3【练习】Practice and Writing (key-words ---sentences ---passage)1. Brainstorming:The students will discuss the key-words and expressions that can be made use of in a letter of advice in groups. Then present their ideas.2. Discussion: the key-words and sentencesSome students are asked to write down their sentences on the blackboard, while others write on the paper. All the students are suggested to make use of some sentence patterns to put forward their suggestions, such as: It’s a good idea to do sth; We’d better; It is of great/vital importance to do sth. It is our duty to; not only…but also; and so on.By analyzing the sentences on the blackboard, teacher will emphasis the importance of making use of good sentence patterns to offer suggestions, which is one of the difficulty points in this class.3. Writing a letterThen, how to organize sentences into a good paragraph? The students are guided naturally to pay attention to these two aspects:(1) Using proper linking wordsStudents are encouraged to write the first and the second paragraph on their paper, using proper linking words and sentence patterns.(2) Comments and PolishMake comments on some students’drafts and polish them with the help of other students. The purpose of this activity is to draw students’attention to the common mistakes in the letter, such as punctuation, spelling, the elements of a sentence and how to present suggestions correctly.(3) Find out the structure of letters of adviceThe teacher will ask students this question:With just these two paragraphs, will it make a complete passage? What else do we need to finish it?A conclusion.Then, the teacher will offer an example about how to write a simple but powerful ending. The students are encouraged to write down their own conclusions.Then, show out.By finishing these three paragraphs, students will find out the structure of the letter: usually, a letter of advice should include three parts: the problem and its effects---suggestions on how to deal with it---draw a conclusion.【设计说明】: 此部分从关注话题词汇和词组，到引导学生运用恰当的建议句型写出正确句子，再学习运用连接词、连句成段写出完整的段落，直至写出属于学生自己的powerful ending，最后课堂上立即修改和完善建议信。
