Section 4　Reading for Writing and Other Parts of the Unit 原|文|诵|读 CHEMICAL VERSUS ORGANIC① FARMING Chemical ② and artificial fertilisers have been in ③ use in farming since the middle of the 20th century. When they were first introduced, many farmers welcomed them as a great way to fight crop disease and increase production. Over time, however what some scientists have found is that their long­term use can sometimes harm both the land and people's health. For example, pesticides can damage the land by killing not only harmful ④ and insects, but also helpful ones. In addition, these chemicals can stay in the soil and underground water sources for a long time. This affects the crops grown on the land and, ⑤， the animals and humans who ⑥ them. Many people worry that these chemicals may make them ill and even cause cancer. In fact, some pesticides like DDT have been prohibited in most countries because of the damage they cause to people and the environment. As for chemical fertilisers, crops grown with them usually grow too fast to be rich in nutrition. They may look beautiful on the outside, but inside there is usually more water than ⑦ ⑧， and they often have less flavour as well. 微|点|清|障 ①organic /ɔːˈɡænɪk/ adj. 有机的；不使用化肥的；有机物的 ②pesticide /ˈpestɪsaɪd/ n. 杀虫剂；除害 ③widespread /ˈwaɪdspred/ adj. 分布广的；普遍的；广泛的 ④bacterium /bækˈtɪəriəm/ n.
