Step 2 Careful 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.

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? Give students some time to retell the text by themselves. If time permits, teacher can ask some of them to read out his or her passage. Step 3
