Example

Chemical fertilizers caused some problems / disadvantages.（中心句）

First, they damage the land by killing the helpful bacteria and pests as well as the harmful ones.（拓展）

What’s more, chemicals also stay in the ground and underground water for a long time. This affects crops, animals and humans, because chemicals get inside the crops and can’t just be washed off. Many of these chemicals in food supply can lead to cancer or other illnesses.（拓展）

Last but not least, fruit and vegetables grown with chemical fertilizers usually grow too fast to be full of much nutrition. They may look beautiful, but inside there is more water than vitamins and minerals. （拓展）In all, chemical fertilizers are not good for land and health.(总概）
