　　I Lead in

　　1 Ask the students some questions, trying to know what they are eating in their daily life.

　　What did you have for lunch?

　　Do you like eating …?

　　Do you think you are eating healthily?

　　2. Present a popular saying and let them think why such thing happens.

　　“吃动物怕激素；吃植物怕毒素；喝饮料怕色素；能吃什么，心里没数。”―――人大代表金志国带到两会上的顺口溜。

　　Why did he say so?

　　Can you give some examples to show what foods are harmful to our health?

　　How can we solve the problem?

　　As people’s living condition improves, more and more people are concerned about what they eat. In fact, more and more become worried about the quality of the food they eat. People now all want to eat green food which does no harm to their health.

　　What food is healthier and safer for us?

　　What we need is natural food-----green food.

　　Do you know how green food is produced?

　　II.    Reading

　　1 Skimming:

　　Today we have a passage which will tell you something about organic farming. Read the passage quickly and find out:

　　What is organic farming?

　　2 Scanning:

　　Find the detailed information about organic farming.

　　Organic farmers prefer to use natural fertilizers for their plants.

　　Why are natural fertilizers better?

　　What problems are caused by using chemical fertilizers?

　　Do organic farmers have and special ways of farming? If they have, what are they?

　　And why do they do so?

　　III. Using language

　　1 Make a plan:

　　As we know, farming is something not familiar to us. But farming is very important for all the people. So today I’d like you to do some farming. There is a big piece of free field near your school. The school is planning to grow some crop in the field. First of all, a plan is needed. So make a plan in your group.

　　What to grow and why?

　　How to develop the soil?

　　What special way to grow it?

　　What special way to take care of your crop?

　　2 Report the plan

　　Do you think what you grow is green food?

　　Do you really think you have made a perfect plan?

　　If others will help to improve your plan, will you be willing to hear about their opinions?

　　3 Further discussion.

　　Present the plan of your group to the neighboring group and exchange your ideas with them, trying to get their advice on your farming to make your plan even more perfect. You have five more sentences to improve your plan.

　　After five minutes, ask several groups to report their plan and tell the whole class what advice they have got from the neighboring group.

　　4 You all have a good harvest. But the problem is what you will do with the harvest. Do you want to sell it and make some money? How about writing a poster? I think it can not only let more people know the food you grow, but also can make your work much easier. So if you want to sell your food quickly, write a poster right now, and try to make it as good as possible.

　　Homework:

　　1. Finish designing the posters.

　　2. Sum up what you have learnt in this unit, including useful words, expressions and new grammar item.
