Question

    To 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 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 don’t need to have fragile glass walls and ceilings. And they can be set up anywhere, including places that don’t get the amount of light greenhouses need.

Since pinkhouses can pack food in huge columns, one of these farms doesn’t 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 traditional farming. Pinkhouses can allow for many more harvests per year since farming doesn’t have to stop in the winter.

Even though pinkhouses are a great way to grow crops, lighting and heating an indoor space is very expensive. It doesn’t make sense to grow foods that take up a lot of space or that we 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 fight crops, rather than a rectangle of one type of plant. Sensors in the fields will measure the soil’s 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 very precise watering and care, all calculated to get the best plant growth and yield.

【解析】

这是一篇说明文。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，第二个是农民采取更智能的种植模式。

1.

细节理解题。根据第三段中They completely control temperature and light, which can help some plants grow twice as well in pinkhouses as they do in traditional farming.可知他们完全控制温度和光线，这可以帮助一些植物在pinkhouses里比在传统农业中长大到两倍。由此可知，pinkhouses可以让植物长得更大。故选D。

2.

推理判断题。根据第四段第一句Even though pinkhouses are a great way to grow crops, lighting and heating an indoor space is very expensive. 和最后两句We will still need to grow those crops in fields. We can start farming smarter.可知，虽然pinkhouse是一个好方法，但是费用很贵，农民依然需要在田野里种粮食，但是要采取更智能的种植方式，强调采取更智能的种植方式，接下来的内容是讲如何采取更智能的种植方式，由此判断出第四段的目的是提出一个新的讨论话题。由此可推知，在第4段中，作者目的是提出一个新的讨论话题。故选C。

3.

细节理解题。根据最后一段中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 very precise watering and care, all calculated to get the best plant growth and yield.可知它们甚至还能探测昆虫，并向智能手机应用发送通知。灌溉系统将与天气预报程序绑定，允许非常精确的浇水和护理，所有这些都能得到最佳的植物生长和产量。由此可知，智能农业的结果是农民将会有更好的收成。故选A。

4.

主旨大意题。根据第一段To 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?可知为了应对一个不断变化的世界，我们也必须改变。把土地变成农田会砍伐森林，加剧气候变化。但是我们需要种植更多的粮食来支持不断增长的全球人口。我们能做什么？再结合全文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，第二个是农名采取更智能的种植模式。所以短文的最佳标题为“保障未来粮食供给”。故选B。
