考研英语阅读真题考研英语二毙考题

2013考研英语阅读真题：考研英语（二）第1篇 In an essay, entitled “Making It in America,” the author Adam Davidson relates a joke from cotton country about just how much a modern textile mill has been automated: The average mill has only two employees today, “a man and a dog. The man is there to feed the dog, and the dog is there to keep the man away from the machines.” Davidson’s article is one of a number of pieces that have recently appeared making the point that the reason we have such stubbornly high unemployment and declining middle-class incomes today is largely because of the big drop in demand because of the Great Recession, but it is also because of the advances in both globalization and the information technology revolution, which are more rapidly than ever replacing labor with machines or foreign workers. In the past, workers with average skills, doing an average job, could earn an average lifestyle. But, today, average is officially over. Being average just won’t earn you what it used to. It can’t when so many more employers have so much more access to so much more above average cheap foreign labor, cheap robotics, cheap software, cheap automation and cheap genius.

But scientists say the farms of the future could be built in tall buildings in some large cities. It may be difficult to believe, but in fact, the technology for growing crops in doors already exists. Farming in the city is already happening. Some vegetables are already grown in greenhouses. Even the scientists at the South Pole research station can enjoy fresh vegetables they grow in their own greenhouse. Experts say indoor farming solves many problems. First, traditional farming takes up a lot of land. Growing crops in tall buildings — called vertical farming（垂直农业）— can solve the problem. Also, fruits and vegetables grown indoors would not face serious threats from insects and weather. Though vertical farms don’t exist yet, experts have created a plan for recycling in such farms. The water from indoor fish ponds would be used to water crops. Gases from crop waste would be used to heat the building. Waste from chicken or pigs would be reused as a source of energy. But experts believe vertical farming is not going to be easy. They say it can be difficult to control climate conditions indoors. Besides, Plants differ in their weather and lighting needs. For example, some plants like warm, sunny weather, but other plants prefer cooler temperatures. That’s not to say these difficulties won’t be overcome —but it will take time. Most experts suggest it may take about 5 to 15 years before the first vertical farms could be created. 【参考译文】 农场出现在城市里（城中农场） 当听到“农场”一词，你可能联想到乡下的母牛和庄稼等等。但科学家说，未来的农场可能会建在一些大城市的高楼里。 此事可能难以置信，可是事实上，在室内种庄稼已经存在了。城市里的农场已经出现，某些蔬菜已经在温室里生长。甚至在南极科考站，科学家们能享用他们在温室里自己栽种的新鲜蔬菜。 据专家们说室内农场可以解决许多问题。首先，传统农场占据大片土地。在高楼里种庄稼（称之为垂直农业）可以解决此问题。再者说，水果和蔬菜室内种植不会受到害虫和气候的威胁。 尽管垂直农场尚未成为现实，但是专家们已经在一些农场创建了再循环计划：把室内养鱼池的水用于浇灌农作物，把来自于农作物的废气用于建筑物的供热，来自于鸡和猪的粪便重新利用作为能源。 但是专家认为垂直农业并不是一件容易的事。他们说，控制室内气候环境是困难的。除此之外，植物对气候和光照需求有差异。例如，一些植物喜好温暖、阳光普照的气候，但另一些植物更喜欢较凉爽的温度。 并不是说这些困难不能克服——但是这将需要花时间。大多数专家指出，建立起第一个垂直农场可能需要五年到十五年的时间。 word “farm” may m ake you think of the countryside.

For example, Business Week predicted in 1975 that electronic only to 4itself several means of payment “would s oon revolutionize the very3of money itself,”　 years later. Why has the movement to a cashless society been so5in coming? Although e money might be more convenient and may be more efficient than a payments system based on paper, several factors work6the disappearance of the paper system.
