In the near future, IOT (The 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 that they are still fresh when they reach their final destination.
Second, vertical farms will be connected to other networks and information systems, including
databases that track the 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, onetenth the water, and no
pesticides. A side benefit of lower energy use is lower CO output of two tons per month, with the added
2
benefit of creating 46 pounds of oxygen every day.
5．How do sensors attached to plants work?
A．By recording farmers harvesting crops.
B．By monitoring farmers working their fields.
C．By analyzing information to preserve crops.
D．By passing information to a control system.
6．According to Paragraph 4, what can the IOT system do?
A．Helping expand the output of crops.
更多资料添加微信号：hiknow_007 淘宝搜索店铺：乐知课堂B．Helping match supply with demand.
C．Helping determine the needs of farmers.
D．Helping move restaurants onto farms.
7．What is the author's attitude towards the future of vertical farming?
A．Negative. B．Indifferent.
C．Optimistic. D．Doubtful.
8．What is the main idea of the text?
A．Voice machines help plants speak up.
B．Farmers are all turning to vertical farming.
C．IOT has brought great innovation to our future life.
D．Vertical farms driven by IOT are a future for agriculture.
II.七选五
Imagine an area 34 times the size of Manhattan. Now imagine it covered ankledeep in plastic waste—
a total of about 19 billion pounds of garbage. __1__.
“We're being overwhelmed (淹没) by our waste，” said Jenna Jambeck, an environmental engineer
who led the 2015 study that determined this astonishing number. __2__， unless something is done to stop
the tide of garbage.
Plastic—a widelyused material—has in many ways been a benefit to humans but it has also caused a
growing problem. Today, plastics are the No. 1 type of garbage found in the sea. Ocean Conservancy, a
nonprofit environmental advocacy group that organises an annual coastal cleanup event worldwide, said
plastic waste makes up around 85 percent of the garbage collected from beaches and oceans.
Ocean Conservancy says plastics are believed to threaten (威胁) at least 600 different wildlife species
(物种). __3__； a growing body of evidence suggests humans are consuming plastics through the seafood
we eat. Research suggests some plastics could be poisonous to humans, and could potentially increase the
risk of health problems.
__4__. At the Economist World Ocean Summit this week, ten nations announced to reduce plastic sea
litter as part of UN Environment's Clean Seas campaign. __5__. Corporations also have a role, as do
individuals. We can start by thinking twice before using singleuse plastic products—and when we do use
them, we should take care to properly throw them off or recycle.
A．The following is what we should do
B．And it's not just wildlife that's threatened
C．And this figure is likely to double by 2025
D．But it's not just countries that need to do their part
E．By 2050, that figure is expected to rise to 1,000 pieces
F．That's how much plastic waste ends up in our oceans every year
G．All of us have an important role to play in dealing with the problems
