When they were first introduced, many farmers welcomed them ____________a great way to fight crop disease and increase production. Over time, however, ______________ some scientists have found is that their long-term use can sometimes harm _______________ the land and people’s health.For example, pesticides can damage the land ___________killing not only harmful bacteria and insects, ____________ also helpful ones. In addition, these chemicals can stay in the soil and underground water sources for a long time. This affects the crops _________________(grow) on the land and, __________ turn, the animals and humans who digest them. Many people worry that these chemicals may make them ill and even cause cancer. In fact, some pesticides like DDT__________________(prohibit) in most countries because of the damage they cause to people and the environment. __________ for chemical fertilisers, crops______________(grow) with them usually grow too fast to be rich ___________ nutrition. They may look beautiful on the outside, but inside there is usually more water_______________ essential minerals, and they often have less flavour as well.As an alternative, some farmers have switched __________ organic farming, and many customers have turned to organic food when they shop at the local grocery. Organic farming is simply farming _______________ using any chemicals. Organic farmers focus on keeping their soil rich and free of disease__________ natural means. For example, many organic farmers use natural waste from animals as fertiliser. This makes the soil in their fields____________(rich) in minerals. It also keeps the air, soil, water, and crops free of chemicals.Organic farmers also use many other methods _______________(produce) rich soil. They often change the kind of crop grown in each field every year. For instance, they may grow corn or wheat in a field one year, and then grow beans there the next. Why different crops are grown is because they put important minerals back into the ground, ________________(make) it ready for the next batch of crops. Organic farmers also plant diverse crops that use different____________(deep)of soil to help keep it rich. For example peanuts grow on the ground’s surface, but many other vegetables put down deep roots. The goal of using different organic farming methods is ______________(grow) good food while avoiding damage to the environment or to people’s health.Some people would prefer to stop the use of man-made chemicals in agriculture entirely. _______________ keeps them from doing so is the fact that chemical farming serves the high demand for food around the world. Organic farming is nowhere near able to meet that need._________________, there is still a long way to find a suitable_____________(solve) that puts sufficient food on the dinner table while _________________(keep)people and the environment as healthy as possible.1___________________2____________________3________________4___________________5____________________6________________7___________________8____________________9________________10___________________11____________________12_____________13___________________14____________________15_____________16_____________________17_________________18_____________19____________________20_______________________21_______________22_________________23_________________ 24_______________________25________________答案1.have been in widespread2.as3.what4.both5.by6.but7.grown8.in9.have been prohibited10.A s11.g rown12.i n13.t han14.t o15.w ithout16.t hrough17.r icher18.t o produce19.m aking20.d epths21.t o grow22.W hat23.T herefore24.s olution25.k eeping第二部分：中英文翻译CHEMICAL VERSUS ORGANIC FARMING化学耕作和有机耕作Chemical pesticides and artificial fertilisers have been in widespread 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 long-term use can sometimes harm both the land and people’s health.自20世纪中期以来，化学农药和人工化肥在耕作中得到了广泛使用。

当它们第一次被引进时，很多农民喜欢使用农药和化肥，把它们作为防治农作物病虫害和提高产量的重要手段。

然而，随着时间的推移，一些科学家发现长期使用农药和化肥会造成土地受损，对人们的健康造成危害。
