First，it can damage the land. Second，it will be bad for our health if we eat its products for long. Third，the products grown with chemical fertilizers contain too much water rather than vitamins and minerals.（P2:提出个人观点 1，并举例论证:化学农业的问题) 我们大多数人认为有机农业比化学农业好，因为化学农业会引起很多问题。首先，它会破坏土地。第二，如果我们长时间吃它的产品会对我们的健康有害。第三，用化肥种植的产品含有太多的水分，而不是维生素和矿物质。 Writing However，organic farming is good for us. On the one hand，it can help to keep the soil fertile and prevent the crops from disease, it makes the crops healthy and strong. On the other hand, eating its products can do good to our health. （阐述观点2，对比：有机农业的好处） 然而，有机农业对我们有好处。一方面，它可以帮助保持土壤肥沃，防止作物生病，因此它使作物健康强壮。另一方面，吃它的产品对我们的健康有好处。 So there are more and more people who are willing to eat organic farming products.（总结观点） 所以越来越多的人愿意吃有机农产品。 thanks EV录屏5.4.2软件录制 Lavf60.16.100 本视频由湖南一唯信息科技开发的EV录屏软件录制, www.ieway.cn Lavf60.16.100 Packed by Bilibili XCoder v2.0.2 $
