In the near future, IoT (Internet of Things) will drive huge innovation (革新) in the way our food is grown. Plants will have a “voice”, not a human voice, but a voice based on data that can tell people, computers, and machines when, for example, they are thirsty, or need more sun, medicine, etc.
Take vertical (垂直的) farms, for example. Farming is moving indoors where the growth of plants can be monitored and controlled. The facilities are built vertically, so growing areas can be put in piles. This greatly reduces the amount of land needed for farming.
From an IoT point of view, vertical farms are connected in two ways. First, small sensors (传感器) in the soil or connected to plants tell a control system exactly how much light, water, and nutrients are needed to grow the healthiest crops. Sensors will also tell vertical farmers when crops are nearing their peak for harvesting at just the right time to make sure it’s still fresh when it reaches its final destination.
Second, vertical farms will be connected to other networks and information systems, including databases that track local demand. For example, local restaurants may input when they need fresh food supplies. And vertical farmers could get that information so they know which crops to grow in what quantities. This type of IoT system would have been unimaginable a generation ago.
Today, vertical farms are being experimented. Yet, the numbers point to a bright future for the industry, especially as the world’s population continues to grow. For example, Green Sense Farms in Chicago is able to harvest crops 26 times a year using 85 percent less energy, one-tenth the water, and no pesticides. A side benefit of lower energy use is lower CO2 output of two tons per month, with the added benefit of creating 46 pounds of oxygen every day.

4.What is the author’s attitude towards the future of vertical farming?

I’ve come back to check on a baby. Just after dusk I’m in a car down a muddy road in the rain, past rows of shackled (戴镣的) elephants, their trunks swinging. I was here five hours before, when the sun was high and hot and tourists were on elephants’ backs.
Walking now, I can hardly see the path with my phone’s flashlight. When the wooden fence post stops me short, I point my light down and follow a current of rainwater across the floor until it washes up against three large, gray feet. A fourth foot twisted above the surface, tied tightly by a short chain and choked by ring of metal spikes (尖刺). When the elephant gets tired and puts her foot down, the spikes press deeper into her ankle.
Meena is four years and two months old, still a child as elephants go. Khammon Kongkhaw, her caretaker, told me earlier that Meena wears the spiked chain because she tends to kick. Kongkhaw has been responsible for Meena here at Maetaman Elephant Adventure, near Chiang Mai, in northern Thailand, since she was 11 months old. He said he keeps her on the spiked chain only during the day and takes it off at night. But it’ s night now.
I ask Jin Laoshen, the Maetaman worker, why her chain is still on. He says he doesn’t know.
Maetaman is one of many animal attractions in and around tourist-crowded Chiang Mai. Meena’s life is set to follow the same track as many of the roughly 3,800 captive (被捕获的) elephants in Thailand. When Meena is too old or sick to give rides—maybe at 55, maybe at 75, she’ll die. If she's lucky, she’ll get a few years of retirement. She'll spend most of her life on a chain.
1.Why does the author decide to come back?
A.To check the baby elephant Meena.
B.To feed those shackled elephants.
C.To release those shackled elephants.
D.To help an injured worker in Maetaman.
2.What can we conclude from the second paragraph?
A.The author is scared walking in the path.
B.Meena is treated badly and very painful
C.Meena only has three healthy legs.
D.One of Meena’s leg is badly broken.
3.What’s the author’s attitude towards those elephants?
A.Indifferent.
B.Critical.
C.Sympathetic.
D.Negative.
4.We can infer that the purpose of the author’s writing is______________.
A.to describe those elephants to attract tourists around the world
B.to draw people’s attention to caring about the fate of those elephants
C.to tell readers the story of a baby elephant in Chiang Mai, Thailand
D.to tell the reason why the number of elephants is decreasing
