1、UNIT 5 单元主题训练.阅读理解ATo deal with a changing world, we have to change as well. Transforming land into farms removes forests and worsens climate change. But we need to grow more food to support a growing global population. What can we do?Scientists have discovered that plants grow best under a certain
2、type of light, which can be provided by red and blue LEDs. The combination of these lights at the right level makes a space look pink. Since “pinkhouses” supply their own light, they dont need to have fragile glass walls and ceilings. And they can be set up anywhere, including the places that dont g
3、et the amount of light greenhouses need.Since pinkhouses can pack food in huge columns, one of these farms doesnt need a lot of land. Farmers can set up pinkhouses in cities. They completely control temperature and light, which can help some plants grow twice as well in pinkhouses as they do in trad
4、itional farming. Pinkhouses can allow for many more harvests per year since farming doesnt have to stop in winter.Even though pinkhouses are a great way to grow crops, lighting and heating an indoor space can be very expensive. It doesnt make sense to grow foods that take up a lot of space or that w
5、e need to grow lots of, like wheat, rice, and corn, in a pinkhouse. We will still need to grow those crops in fields. We can start farming smarter.Farmers will use satellite imagery to figure out exactly where to plant each crop. Think of a mixture of just the right crops, rather than a rectangle (长
6、方形) of one type of plant. Sensors in the fields will measure the soils water level, temperature, and chemical content. They will even be able to detect insects and send out notifications to a smartphone app. Irrigation systems will be tied to weather forecasting programs, allowing for very precise w
7、atering and care, all calculated to get the best plant growth and yield.语篇解读：本文是一篇说明文。文章讲述了如何促进农业生产的两个措施：第一个措施是“粉房子”种植模式，第二个是农民采取的更智能的种植模式。1From the text, we know that the pinkhouse _.Acovers lots of spaceBneeds enough sunlightCis made of glass or plasticDcan make plants grow larger解析：选D细节理解题。根据第三段中
8、的“They completely . traditional farming.”可知，“粉房子”可以完全控制温度和光线，这使得一些在“粉房子”里的植物生长得比传统农场里的植物好一倍，所以“粉房子”能使植物长得更大，故选D项。2What does the author intend to do in Paragraph 4?ASummarize the previous paragraphs.BEmphasize the advantage of pinkhouses.CIntroduce a new topic of the discussion.DAdd some background i

Whats more, traditional farming techniques are based on conditions that are not applicable to vertical farming. Therefore, without t
13、aking time to understand the science, vertical farming is not likely to be able to live up to its implied promises.The cost of powering LED grow lights is one of the biggest problems a vertical farm must overcome. Dr Louis Albright at Cornell University has characterized vertical farms as “pie-in-th
14、e-sky” businesses. He famously calculates, for instance, that the cost of a loaf of bread would be D|S24 if farmed indoors the cost is too high. Gauthier acknowledges that energy prices are high but points out that scientific work has shown that only about 6% of available sunlight is used in crop ph
15、otosynthesis (光合作用), so there may be ways of growing the same plants with less light.Gauthier also points out that while energy costs are a bit high, vertical farming does create high efficiencies in other areas. Water usage may be significantly reduced because the same water can be recycled time an
16、d again. Fertilizer use can be greatly reduced and pesticides for pest control are unnecessary. Its clear that vertical farming offers real value to society.The future is probably mixed. In some environments the Middle East, for instance a move to vertical farming is a no-brainer. An indoor farm in
