Step Ⅰ Greeting and revision

Step Ⅱ Reading

There are three tasks in this step. First, teacher can ask students to read the articles one paragraph by one paragraph. Ask them some questions about these passages. There are three paragraphs in the article. In each passage, there are one or two questions. When students finish these questions, they will find that the structure of the text has turned up.

T: In the last periods we talked about agriculture. As people’s living condition improves, more and more people are concerned about what they eat. In fact more and more people become worried about the quality of the food they eat. Because more and more farmers use chemical fertilizer instead of natural waste from animals and they use poison to kill insects to protect their plants. So people now all want to eat green food which does no harm to their health. They are more concerned about organic farming. Now let’s read the text and know something about organic farming.

Task 1: Questions about the text.

Show the questions on the screen:

1. What is the organic farming? 2. What is the advantage of using natural fertilizer? 3. What is the disadvantage of using chemical fertilizers? 4. What’s the main idea of paragraph 3? 5. Why do farmers grow their crops in such ways?

T: Boys and girls, today we’ll read the text one paragraph by one paragraph. Now please read the first paragraph quickly, and find the answer to the first question: what is the organic farming?

S1: Organic farming refers to crops growing with natural rather than chemical fertilizers.

T: Good. Now read the second paragraph quickly and find the answer to this question: what are the advantage of using natural fertilizer?

S2: Make the soil richer in minerals and so more fertile.

T: anything else?

S3: Reduce diseases in crops and help them grow strong and healthy. Besides, keep the air, soil and water as well as the food supply free from chemical.

T: What is the disadvantage of using chemical fertilizers?

S4: Let me answer it. There are three disadvantages. Firstly, leaving chemicals in the ground for a long time is not good for the soil or the water supply. Secondly, farmers often grow the same crop year after year. As a result, the soil gets exhausted. Thirdly, chemical fertilizers kill both helpful and harmful bacteria and pests.

Main idea of the passage

Chemical fertilizers can cause many problems, so organic farming is becoming

more popular.

Structure of the text

I using chemical fertilizers for a long time can hurt the land and also people’s health

II Problem caused by chemical fertilizers

1. Damage the land by killing the helpful bacteria and pests as well as the harmful ones

2. Lead to cancer or other illness.

3. Food grown with chemical fertilizers look beautiful, but inside there is usually more water than vitamins and minerals.

Ⅲ Organic farming is becoming more popular with some farmers and many customers after these discoveries came out.

IV Other methods to keep the soil fertile.
