roading, biking, and even climbing.”可知，Sedona是喜欢远足的游客的目的地。

B
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.
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?
更多资料添加微信号：hiknow_007 淘宝搜索店铺：乐知课堂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.
答案：DBCD
【语篇解读】 本文是一篇说明文。文章主要以垂直农场为例介绍了在不久的将来，物联网将推动
粮食种植方式的巨大创新。
5．答案与解析：D 细节理解题。根据文章第三段中的“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”可知，传感器将最健康的农作物生长所需要的光、水和营养等信息传递给控制系
统。故选D。
6．答案与解析：B 细节理解题。根据文章第四段中的“Second, vertical farms will be
connected to other networks and information systems, including databases that track the local demand.”可
知，垂直农场将与其他网络和信息系统相连，包括追踪当地需求的数据库，再结合后面的例子可知，
物联网系统有助于使供应与需求相匹配。故选B。
7．答案与解析：C 观点态度题。根据文章最后一段中的“Today, vertical farms are being
experimented. Yet, the numbers point to a bright future for the industry”可知，作者对垂直农场的未来持
乐观态度。故选C。
8．答案与解析：D 主旨大意题。根据文章第一段中的“In the near future, IOT (The Internet of
Things) will drive huge innovation (革新) in the way our food is grown.”及第二段中的“Take vertical (垂
直的) farms, for example.”可知，文章主要以垂直农场为例介绍了在不久的将来，物联网将推动粮食
种植方式的巨大创新。故选D。
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
更多资料添加微信号：hiknow_007 淘宝搜索店铺：乐知课堂(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
FCBGD
【语篇解读】 本文属于议论文，介绍塑料垃圾问题越发严重，不但威胁野生动物，还影响人
类自己，需要全世界通力合作来应对。
1．答案与解析：F 根据前一句 Now imagine it covered ankledeep in plastic waste—a total of
about 19 billion pounds of garbage.可知，塑料垃圾总共为190亿磅左右，F选项“这就是每年被丢到
海洋里的塑料垃圾的数量”与前文呼应，故选F项。
2．答案与解析：C 根据后文unless something is done to stop the tide of garbage (除非采取一些
措施来减少垃圾)可知，C选项“预计到2025年，这个数字很可能会翻倍”与后文形成条件关系，
切题，故选C项。
3．答案与解析：B 根据后文a growing body of evidence suggests humans are consuming plastics
through the seafood we eat可知，越来越多的证据显示人类通过食用海产品也摄入了塑料，B选项
“不仅野生生物受到威胁”切题，故选B项。
4．答案与解析：G 根据本段后文ten nations以及Corporations可知，这个问题需要全世界共
同合作，G选项“所有人都能够为解决此问题发挥作用”切题，故选G项。
5．答案与解析：D 根据下一句Corporations also have a role, as do individuals.可知，企业和个
人也能发挥作用，D选项“不仅仅是国家需要尽到责任”引出下文，切题，故选D项。

【文章大意】 本文是一篇说明文。文章介绍了中国第一条太阳能公路的建设过程。在这条公路上,
太阳能电池板被放置在透明的混凝土下面。
1.construction 考查词形转换。此处作主语,故用名词construction。
2.lying 考查非谓语动词。因solar highway与lie之间是主动关系,故用现在分词lying作后置定语。
3.sizes 考查名词复数。根据two可知,此处应用复数形式sizes。
4.is 考查时态和主谓一致。此句是全部倒装句,句子是一般现在时,主语是a layer,因此动词用第三人
称单数,故填is。
5.itself 考查反身代词。此处指“道路本身”,故用itself。
6.which 考查非限制性定语从句。此处connecting the grid是先行词,指物,在后面的非限制性定语从
句中作主语,故填which。
7.built 考查动词时态。空处作谓语动词,根据earlier this year可知,句子用一般过去时,故填built。
8.the 考查定冠词。此处表示特指,用定冠词。in the city of…在……市。
9.of 考查介词。keep…clear of使……摆脱……。
10.wirelessly 考查副词。此处charge是动词,需用副词修饰动词,故填wirelessly。
