2019-2020年高一英语 Unit19《Modern agriculture》备课资料旧人教版第一册一、异域风情1.Modern FarmPigs,fishponds and crops—all housed in tall buildings.This is a vision of industrial farming in the Netherlands(荷兰).In a world concerned about the environment and transport,would it not make sense to concentrate food production next to a harbor and an airport?And since humans can live in tall buildings,why not pigs and fish?The creative minds behind a government report suggest just this for a site at Rotterdam very close to mainland Europe's largest port.The scale is vast:imagine 10 football fields,six floors of equal area,a total of 500 acres(亩)stretching skywards.The building,known as Deltapark,visualizes(让人想象到)300 000 pigs,1.2 million chickens,tens of thousands of fish and a giant vegetable growing area all under one roof.The pigs could enjoy more space than on an average pig farm,and end their days in the slaughterhouse downstairs.Space without daylight in the giant building could be used for cultivating mushrooms which grow well in the dark.Higher up,green houses full of tomatoes and flowers,grown in nutrient solution collected from elsewhere in the building,would profit from the light.The system is theoretically a plete farming cycle,with one activity feeding another and everything being recycled.Deltapark is to be run by managers,not farmers.It has nothing to do with agriculture as we now know it,and so far,only exists on paper.But the idea has createda heated debate(讨论)in the Netherlands and attracted attention abroad.2.Automatic FarmingCan hard work be replaced by machines in agriculture?Yes,man is trying out(试验)automatic farming.It is fun to watch a machine picking tomatoes.The strange machine sails like a ship across a sea of plants.In its front is a hole.As the machine moves forward,tomato plants are pulled into the hole.The tomatoes are gathered while the rest of the plants are thrown back onto the fields.Twelve workers sit on top of the machine.They rapidly pick out the bad fruit from the tomatoes.A red stream of ripe tomatoes is being sent into a cart that is pulled alongside the machine.One driver and twelve workers can pick in an hour ten tons of a new kind of tomato.Without the invention,it would take 60 men to do the job.Not all plants cooperate(合作)well with the farming machines.Take lettuce(莴苣)for example,seeds plants in the same field in the same time ripe at different times.The only way to tell a ripe head of lettuce is to look at it and feel it.And now there is a machine even to do that!There is a special machine to test lettuce.When it moves over one that feels right,it sends a signal back to the picking machine which goes behind.The cuttingand picking is done satisfactorily by this set of machines.二、知识归纳(一)against的用法(1)作“反对”解，相当于“in opposition to”There were 20 votes for him and 12 against him.有二十票赞成他而十二票反对他。
