Soil becomes rich and healthy. 3. They plant crops that need surface soil and next crops that grow at a deeper level. So the wind and water does not carry away the soil. All the richness of the soil is used. For Exercise 3, here is a simple: Organic farming means crops growing with natural fertilizers instead of chemical ones. Yhe natural fertilizer which is natural waste from animals does good to soil. It makes the soil richer in minerals while chemical fertilizers damage the soil, leaving chemicals fertilizers in the ground for a long time and killing both helpful and harmful bacteria and pests. Organic farmers keep the soil rich and healthy by changing plants every two or three years, planting different crops in different layers and planting grass between crops to prevent wind or water from carrying away the soil. Step 4 Learn the Language points

Show the following sentences on the screen: 1. reduce v. make sth smaller in size, number, degree, price, etc e.g. This company tries to increase profits by reducing costs. 2. We have reduced expenses this year. 3. supply v. give sb. sth. that is needed or useful e.g. He kept me well supplied with cups of coffee while I wrote the report. The shop was unable to supply what she wanted. In Britain milk is supplied to each house in bottles. 4. whatever

5.refer to v. mention or speak of sb. / sth. e.g. When I said some people are stupid, I wasn’t referring to you.

Don’t refer to this matter again. 6. year after year e.g. The villagers plant trees on the hill year after year Step 5

Discussion group work: Divide the class into groups of four，and each of them has to do one of the following discussion.

Show students the questions:

1.What is the advantage of using natural fertilizer? 2.What is the disadvantage of using chemical fertilizers? 3. Talk about the agriculture programmes in your hometown. Then give the students enough time to share their findings with other groups. At last, it is a good idea to ask the students to speak out what they find to the class. And the teacher gives some evaluation. 前面两题围绕着课文，为了熟悉课文，我们设计第三个问题是出于我们随着人民生活水平的提高，在我们这些地方农业问题不是温饱问题，无危害的粮食和蔬菜，生态示范园的建立，更是人们关注的重点与热点。我们在这个方面向课外延伸，学会辨别有害食品与绿色食品，和生态示范园的建立（如浙江晨龙太空农业科技园(http://www.cn-chenlong.com/或中国晨龙.com)航天育种基地种植的经过"神六"的"太空丝瓜"、" 太空番茄"，"太空西瓜"），从而激发学生热爱农业科学，以及对当代农民带来的益处。
