Using Language Ⅱ

教学过程

Step1. Lead-in Show the students some pictures of green food and junk food and ask them some questions as follows: 1. Which food do you prefer to eat, why? 2. Which of those do you think are green foods and what will you think of when we mention the green food? 设计说明：通过观看图片激发兴趣，回答问题启动学生绿色食品的意识，打开对绿色食品相关话题比如说农场之类等，激活其农业方面的相关思维。

Step2. Reading 教师让学生阅读下面一篇短文，完成文后的任务。

What is green food? Green food, which is healthy and safe for people’s health, refers to the food growing with natural rather than chemical fertilizers. The fertilizer that “green” farmer use is natural waste form animals. They believe that putting this in their fields, which are away from industrial areas and dirty water supplies makes the soil richer in minerals and more fertile. Besides, they can keep the air, the soil and water as well as the food supply free from chemicals. As everyone knows, green food is usually more expensive to grow than other food which is not safe so that many people would rather buy ordinary food at a much lower price without caring about their health. This means green food doesn’t sell well in China, which worries“green”farmers.

Lao Wang from Nanxijiang Farm, for example, learns to grow green fruits such as watermelons and he gets a big harvest this year. His watermelons sell at 8yuan per kg while the ordinary ones at 4yuan per kg. The problem is that he doesn’t know how to let people in cities know how special his green melons are and may not be able to sell them out before they go bad. Questions: 1. What does the writer mainly want to tell us?

He wants to tell us something of green food such as the advantages and the disadvantages of it. 2. What are the advantages and the disadvantages of the green food according to the passage? Advantages: a. healthy and safe for people’s health

b. grown with natural fertilizers c. away from industrial areas and dirty water supplies d. free from chemicals Disadvantages: a. more expensive than other food which is not safe b. green food doesn’t sell well 3. What is Lao Wang’s trouble?

He doesn’t know how to let people in cities know how special his green melons are and may not be able to sell them out before they go bad. 设计说明：通过阅读，进行语言输入，训练学生阅读技巧如抓主旨大意和细节的能力。弄清绿色食品的利弊和理出老王的烦心事，为顺利过渡到下一个环节作好铺垫。（另外这篇文章是笔者在原有教材基础上，进行了重整以更加适合学生的认知水平，课本上的阅读文章短而浅显）

Step3. Discussion Activity: Work in pairs and discuss which of Lao Wang’s watermelons would you prefer to buy, your opinions must be based upon the above advantages of green food, using the following expressions, especially the underlined ones. I would rather… I don’t like…because…

I’d prefer… because… It’s a great pity that…

Should I we …? It’s better to …

This is good value because… If I have a choice I’d choose…because…

What is the advantage of …? You need to…

设计说明：通过讨论，开启学生思维，为进入到对话环节做准备, 巩固和运用本单元的功能项目并且有所侧重。

Step4. Dialogue production Activity: Work in pairs to help Lao Wang solve his problem. One acts as a customer, the other acts as Lao Wang, who is trying to persuade his customers to buy his

watermelons, again using the above expressions. Some pairs will be invited to act your dialogues out. 设计说明：这个环节体现了任务型教学的理念，即学中用，用中学。让学生在具体语境中得体地运用本单元的功能项目,也为下一步写作作好铺垫。

Step5. Pre-writing What other ways can you think of to help Lao Wang sell his products well? Yes, make a poster or an advertisement. Let’s begin.

Show two posters of which one is well designed and the other is ordinarily designed to the students in order to tell the differences between them and decide which is better. Then draw their attention to the better one. The format of a poster should be known to the students. Also the students should be guided to be able to use attractive heading, beautiful pictures and persuasive words, creative design and direct reasons to form their poster. 以下是两则海报示例及对学生进行海报制作的指导：

Sample 1 sample 2 Reference: 1. The structure of a poster: Sample 1 sample 2 ▲Main heading

▲Part 1 Explain what you sell

▲Part 2 Reasons to buy

(in shortened sentences) ▲Part 3 Impressive slogans

An attractive picture ▲ Main heading

▲Part 1 Impressive slogans

▲ Part 2 Reasons to buy

(in shortened sentences) ▲ Part 3 Explain what you sell

An attractive picture 2. Useful words and expressions:

Healthy and safe; free of chemical fertilizer; rich in nutrition; high in ; grown away from; be certain to ; natural fertilizer; Follow your desire! This is one step on the road to a …world!

It’s best choice ! just do it!

设计说明：展示两副海报，通过比较，让学生判断其优劣，然后引导学生研究有特色的那副海报，其结构、标题、图片、语言表达等，从而培养学生的鉴赏力，同时给学生提供范本和可能用到的词句供他们运用和模仿。在这一环节里，教师尤其要引导学生品味海报里的语言表达，给出足够的时间让他们讨论和酝酿自己的语句。

Step6. While-writing Activity: Work in groups of 4 and design your best posters for Lao Wang to sell one of his green fruits. Each of the four should be assigned a concrete job such as deciding the heading, drawing the beautiful pictures and using the most attractive words and expressions. 设计说明：这个环节是本节课的重要环节之一，经过前面几个环节的层层铺垫和语言输入，来达到语言的有效输出。要求学生把学到的语言知识运用到做事中来，体现学以致用的原则；在手段上采用小组合作分工的方式，激发学生的合作意识，共同探究共同分享，感受成功和快乐。

Step7. Post-writing Give the assessment of the works to the class and then ask some groups to show their works on the screen. Have comparisons of the presented works and then the teacher gives the exact and scientific evaluations. Assessment Self(自评) Peer (同伴互评) Content (5) Does the poster have a clear structure（结构）? （2）

Does your poster include persuasive reasons？（2）

Grammar(2) Do you use tense correctly?(1) Is your spelling correct?(1) Language

(3) Do you use any good expressions learnt from this class?(1) Do you use attractive and brief sentences?(2) Total marks (10) 设计说明：（１）

引导学生进行自我评价和互评，它不仅符合新课程所倡导的合作、交流和探究的学习理念，而且有益于学生认识自我，树立自信；有助于学生反思和调控自己的学习过程，从而促进综合语言运用能力的不断发展。

（２）教师一要给学生提供评价表，以便对自己的作品作出正确的评价；二要运用鼓励和激励性的语言给予综合评价，做到科学准确，简洁明了，对学生有示范性的作用。

Step8. Summary In this class we have made it clear what green food is and we have offered our help to Lao Wang to solve his problem by persuading customers to buy his products and making a poster for him. I really appreciate your job. Well done! I hope green food will be always on your dinner table and you will be always healthy with green food. 设计说明：重点环节结束时总结话题可以帮助学生加深对本节课内容的理解，让学生回味本节课的活动，进一步理清思路，结束本单元的学习。
