Chemical farming brings high crop output to solve global food shortage, yet it causes great harm to environment and human health. By contrast, organic farming is eco-friendly and safe, but it has obvious limitations in production efficiency. It is worth discussing which farming method is more suitable for future agricultural development. 三、课文精读问答（P56） Read the text, and then answer the questions. 1. Why did many farmers welcome the introduction of chemical farming? Answer: Because chemical pesticides and fertilisers can help farmers fight crop diseases and increase production effectively. 2. What concerns many people about the use of pesticides? Answer: People are concerned that residual chemicals in soil, water and crops may make people sick and even cause cancer. 3. What is one problem with the use of chemical fertilisers? Answer: Crops grown with chemical fertilisers grow too fast to be nutritious. They contain more water than essential minerals and taste worse. 4. How is organic farming different from chemical farming? Answer: Organic farming avoids all man-made chemicals and adopts natural ways to protect soil and crops, while chemical farming highly relies on artificial pesticides and fertilisers. 5. Why do organic farmers change the kind of crop grown in a field every year? Answer: Different crops can return essential minerals to the soil, making the soil fertile for future crop planting. 6. What is the goal of using organic farming methods? Do you think it can be reached? Why or why not? Answer: Its goal is to produce safe food without damaging the environment or people’s health. It can be achieved in the long run, though organic farming cannot meet the huge global food demand at present. 四、段落主旨匹配与细节填空 Match the main ideas (A—D) below with the paragraphs.

There is no doubt that chemical farming can increase crop output quickly to meet global food demand. However, its long-term use destroys soil ecology, pollutes water sources and leaves harmful chemicals in crops, which threatens human health. By contrast, organic farming uses natural methods to keep soil fertile and produce safe, nutritious food without pollution. It’s a pity that it costs more and cannot satisfy huge food needs at present. Still, it is the sustainable future of agriculture. From my point of view, we should popularize organic farming steadily to balance food supply and environmental protection. 三、课文配套专项题型训练 1. 词形填空（贾思勰《齐民要术》） attain　be comprised of　depth　diverse　essential　for instance　output　soil Jia Sixie was a government official from Shandong Province who conducted a lot of agricultural research in the sixth century.

Chemical farming can raise crop output quickly to meet global food needs. However, long-term use of chemicals damages soil quality, pollutes water sources and threatens human health. In my eyes, it is a short-sighted farming method. Without a doubt, organic farming is more sustainable. It uses natural resources to protect soil ecology and produce safe, nutritious food. Though it has limitations in output at present, it is the best choice for long-term agricultural development. I believe green organic farming will create a better future for mankind. 14 / 17 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $ Unit 5 Assessing Your Progress （写作课讲义） 目录 1. Lead in 2. Pre-writing 3. While-writing 4.
