第 13 讲 阅读理解主旨大意题 （练）
A
A new product from Google may help people solve their sleep problems, but some privacy rights groups are
concerned.
Google showed off its newest Nest Hub home assistant device on Tuesday. In addition to recognizing your
voice, showing pictures, videos, news and weather, it can also track your sleep. The basic model costs about $100
and the sleep-tracking technology will be available for free for the rest of 2021. The sleep tracker makes Google’s
product different from a similar home assistant from Amazon. If you put the Nest Hub beside your bed, it can
follow how you sleep. That is because of a new computer chip called Soli, which can sense motion. Some people
may like the new technology because they would not have to wear another device to bed. Some companies make
products people can wear on their wrist to track their sleep.
Google says the new Nest Hub will create reports each week that show how long and how well a person
sleeps. It will also show if they snore, cough or wake up often. The company said it studied 15,000 people over the
course of 110,000 nights to develop the technology.
For people who want to know more about their sleep, the device sounds like a good idea. But, people who pay
attention to privacy are worried what Google might do with the information it is gathering. Jeff Chester is one of
those people. He is the director of the Center for Digital Democracy. “Google’s goal is to monetize every cell of
your body,” he said.
Google recently bought FitBit, a company that makes a health tracker people can wear on their wrist. Some
technology experts think Google may find a way for the Nest Hub to work with the FitBit.
Google says the sleep tracker has a lot of privacy protections. For example, it will only work if the user turns it
on. The company said it will not use a person’s sleep information to try to sell advertising. But Chester said he is
not so sure that promise will be kept.

BHave you ever heard about Black Friday and Cyber Monday? Surely, they are all about finding the best deals
on holiday gifts for yourself and family members. And have you heard about GivingTuesday? Here is something
about it!
GivingTuesday is observed annually on the Tuesday after Thanksgiving, which encourages people to help
those in need by making financial donations or doing good in their local community. The “Global Day of Giving”
was started in 2012 by New York City nonprofit 92nd Street Y and the United Nations Foundation.
Unlike Black Friday, GivingTuesday serves a more altruistic purpose. In its first year, the movement brought
in almost $10 million for charities, and things have only improved since. In 2019, many GivingTuesday social
media campaigns worldwide helped raise an amazing $ 1.9 billion from 27 million donors! Over the past five years,
many higher education institutions have also been using the Tuesday after Thanksgiving to ask alumni for
donations. In 2019, the University of Michigan, which calls it Blueday, received 5887 gifts totaling over $4 million,
while Pennsylvania State University raised $710 000 to benefit over 85 University programs.
Though donating money certainly helps, there are many other ways to support the great cause, especially
during the COVID-19 pandemic. You can video tutor kids struggling with online learning, or team up with an adult
to get groceries or medications for an elderly neighbor. Alternatively, call on your peers to help you with a service
project that addresses an issue close to your heart, or pick one from the several ideas suggested on the
GivingTuesday website. You can also donate your gently-used clothes and toys to local shelters, or mail a
handwritten note to a grandparent or a friend you miss seeing.
What are you going to do to make a positive difference in your community on GivingTuesday? Let us know
by adding your comments below!
5．Why does the author mention Black Friday and Cyber Monday in Paragraph 1?
A．To make a comparison. B．To lead to the topic.
C．To arouse readers’ interest. D．To express his doubt.
6．What’s the aim of GivingTuesday?
A．To promote the development of economy. B．To attract people to buy more holiday gifts.
C．To call on more universities to donate money.D．To encourage people to help those in need.
7．What does the underlined word “altruistic” in Paragraph 3 mean?
A．Selfless. B．General. C．Specific. D．Complex.
8．What is Paragraph 4 mainly about?
A．Where people can offer their kind help. B．What people can do on GivingTuesday.
C．How people can stay safe during COVID-19.D．Why people need to support the great cause.【语篇解读】本文是一篇说明文。文章介绍了GivingTuesday的起源、发展以及在这一天人们做的慈善活
动。
5．B【解析】推理判断题。根据第一段“Have you ever heard about Black Friday and Cyber Monday? Surely,
they are all about finding the best deals on holiday gifts for yourself and family members. And have you heard
about GivingTuesday? Here is something about it!(你听说过黑色星期五和网络星期一吗？当然，他们都可以
来为自己和家人找到最划算的节日礼物。你听说过“GivingTuesday”吗？这里有一些关于它的东西！)”可推
知，作者在第一段提及Black Friday和Cyber Monday这两个节日是为了更好地引出文章的主题——
GivingTuesday。故选B。
6．D【解析】细节理解题。根据第二段中“GivingTuesday is observed annually on the Tuesday after
Thanksgiving, which encourages people to help those in need by making financial donations or doing good in their
local community.(感恩节后的周二是一年一度的“给予星期二”，鼓励人们通过捐款或在当地社区做善事来
帮助那些需要帮助的人)”可知，GivingTuesday旨在鼓励人们通过捐款或为他们所在的社区做好事来帮助那
些需要帮助的人。故选D。
7．A【解析】词义猜测题。根据第二段中“GivingTuesday is observed annually on the Tuesday after
Thanksgiving, which encourages people to help those in need by making financial donations or doing good in their
local community.”及画线词后文“In its first year, the movement brought in almost $ 10 million for charities”可知，
GivingTuesday旨在鼓励人们通过捐款或为他们所在的社区做好事来帮助那些需要帮助的人，而在庆祝这个
节日的第一年，这项活动为慈善机构带来了近1000万美元的捐款。由此可知，GivingTuesday的目的是帮
助别人，所以画线词所在句表示GivingTuesday服务于一个更无私的目的。故画线词应意为“无私的”。
A. Selfless.无私的；B. General.一般的；C. Specific.特殊的；D. Complex.复杂的。故选A。
8．B【解析】主旨大意题。根据第四段“Though donating money certainly helps, there are many other ways to
support the great cause, especially during the COVID-19 pandemic. You can video tutor kids struggling with online
learning, or team up with an adult to get groceries or medications for an elderly neighbor. Alternatively, call on your
peers to help you with a service project that addresses an issue close to your heart, or pick one from the several
ideas suggested on the GivingTuesday website. You can also donate your gently-used clothes and toys to local
shelters, or mail a handwritten note to a grandparent or a friend you miss seeing.(捐款当然有帮助，但也有许多
其他方式支持这项伟大的事业，特别是在新冠肺炎大流行期间。你可以通过视频指导在网上学习中遇到困
难的孩子，或者与成年人合作，为年老的邻居购买杂货或药物。或者，让你的同龄人来帮助你解决一个你
最关心的问题，或者从“给予星期二”网站上的几个建议中选择一个。你也可以把旧衣服和玩具捐给当地
的收容所，或者给你没能见到的祖父母或朋友寄张手写的便条)”可知，第四段主要介绍了在新冠疫情期间，人们在GivingTuesday这一天，除了捐款还可以做的事情。故选B。
C
In previous recessions (经济衰退), billionaires were hit along with the rest of us; it took almost three years for
Forbes’s 400 richest people to recover from losses caused in 2008’s Great Recession. But in the coronavirus
recession of 2020, most billionaires have gotten richer than ever before.
Billionaires increased their new billions just as millions of other Americans ran into terrible financial
problems. More than 20 million people lost their jobs at the start of the pandemic. Food banks across the country
are preparing for another great increase in demand. Why are American billionaires doing so well while so many
other Americans suffer? People may find part of the reasons from the following fact. Stocks (股票) are
overwhelmingly owned by the wealthy, and the stock market has recovered from its early-pandemic depths much
more quickly than other parts of the economy.
But some billionaires are also benefiting from economic and technological trends that were accelerated by the
pandemic. Among these are the owners and investors of retail giants like Amazon, Walmart, Target, Dollar Tree and
Dollar General, which have reported huge profits this year while many of their smaller competitors were defeated
completely as the coronavirus spread.
Then there are companies that have bet on the rapid digitization of everything Eric Yuan, the chief executive of
Zoom, became a billionaire in 2019. Now he is worth almost $20 billion. Dan Gilbert, the chairman of Quicken
Loans, was worth less than $7 billion in March, now he commands more than $43 billion. But there is a great deal
of stratification (层化) even among billionaires—richer billionaires got even richer in 2020 than the poorer ones
did. Jeff Bezos, Amazon’s funder, was worth about $113 billion at the start of the pandemic. Now he is worth $182
billion. Two years ago, Bezos was the only “centibillionaire” on earth—the trendy neologism (a new word) for
people whose wealth exceeds (超过) ￥100 billion.
9．What does the author mainly tell us in the passage?
A．Food banks are not enough in the United States.
B．The richest kept getting richer even in the pandemic.
C．The stock market recovered before the pandemic started.
D．400 richest people recovered from losses in the pandemic.
10．What is “part of the reasons” that is implied in Paragraph 2?
A．The American inequality.
B．The recovery of stock market.
C．The effect of the pandemic.D．The food shortage across the country.
11．What is one of the changes during the pandemic?
A．The decline of digital games.
B．More money lent to people by banks.
C．The trend of technology acceleration.
D．High profit earned by smaller companies.
12．Why does the author refer to “centibillionaire” as a “neologism”?
A．It is a new title in the stock market after the recession.
B．It is a new way of solution to poverty through the world.
C．It is a newly established company during the pandemic.
D．It is a new term for people whose wealth exceeds $100 billion.
【语篇解读】这是一篇说明文。在新冠疫情期间，大多数亿万富翁比以往任何时候都更富有。文章对这种
现象进行了介绍和分析。

and the stock market has recovered from its early-pandemic depths much more quickly than other parts of the
economy.”（股票绝大多数由富人持有，股市从疫情早期的深度中复苏的速度远远快于经济的其他领域。）

斯是唯一的“centibillionaire”——表示一个人的财富超过￥1000亿的时尚新词）可知，因为这是一个新词，

Not long ago, Linda Khan was sitting by a hospital bed in Houston, feeling ill at ease. Beside her lay her father
who needed a heart surgery. The two of them had engaged in nothing but depressing small talk. Then, her eye fell
on a pile of books. She picked up one, and started to read it out loud. "Right away it changed the mood and
atmosphere," she says. Reading gave the daughter a way to connect with her father. Listening allowed the fathertravel on the sound of his daughter's voice into a place where he felt himself again. “From then on," Khan says, “I
always read to him."
In a 2010 survey in the United Kingdom, elderly adults who joined weekly read-aloud groups reported better
concentration, less anxiety, and an improved ability to socialize. The survey authors owed these improvements in
large part to the “rich, varied diet of serious literature" that group members consumed, with fiction encouraging
feelings of relaxation and calm, poetry fostering focused concentration, and narratives giving rise to cognitive (认
知的) thoughts, feelings, and memories. In truth, almost any kind of reading to another person can be beneficial.
Readers get rewards too. For Neil Bush, the late-life hospitalizations of his famous parents, George H. W. and
Barbara Bush, became opportunities to repay a debt of gratitude. “When I was a kid, they would read to me," he
said. With his parents in and out of care, “We've been reading books about Dad's foreign policy and, more recently,
Mom's autobiography." Bush went on, his voice thick with emotion, “And to read their amazing life to them has
been a remarkable blessing to me, personally, as their son."
To many people, reading to parents may seem so far outside the normal range of regular activities, and it may
even feel odd and improper. However, there are still a lot many who brave the momentary strangeness of reading to
elderly adults and both reader and listeners are, to borrow a phrase from Wordsworth, surprised by the joy of it.
17．What did reading offer to Linda and her father?
A．A way to establish a bond. B．A way to travel together in reality.
C．A way to treat the disease. D．A way to engage in learning.
18．What is Paragraph 2 mainly about?
A．Improvements in mental health. B．Benefits of reading to others.
C．Changes in cognitive process. D．Development of social skills.
19．What does Neil Bush's experience prove?
A．Reading benefits more than the listener
B．Parents should red more to their kids.
C．Children should show their gratitude.
D．Reding to parents is children's duty
20．How does the author feel about reading to an elderly adult?
A．Improper and odd. B．Abnormal but worthy.
C．Rewarding and joyful. D．Interesting but unnecessary.

者也有收获，紧接着以Bush的故事来论证这个观点，因此推断从Bush的经历可以证明阅读不仅仅使听者
获益，故选A。
20．C【解析】推理判断题。根据最后一段的“However, there are still a lot many who brave the momentary

Smartphones, tablets and other digital devices can be addictive. They affect sleep. They draw kids into an
alternate universe, often distracting（使分心）them from more productive-and healthier-real-world activities. And
they are often linked to anxiety and depression, learning disabilities and obesity（肥胖）. Yet for many teenagers,
cellphones and social media are also absolutely necessary tools for planning their social lives, keeping up with
schoolwork and staying in touch with out-of-town friends and relatives.
How can parents make the most of the constructive uses of screen-based technology while minimizing its
harmful effects？
The key is helping kids use technology as a tool, not a toy, “where there’s some purpose other than the
medication of boredom,” says Jim Taylor, a psychologist and author of the book Raising Generation Tech：
Preparing Your Children for a Media-fueled World. Taylor, like many other medical and mental health
professionals, advises parents to set limits and stick to them. They should restrict the amount of time their kids
spend on devices, create tech-free zones-no cellphones in their bedrooms, for example-and tech-free times, such as
at the dinner table, in restaurants and on family outings.Perhaps the best thing you can do is serve as a good role model by exhibiting the same online behavior you
expect of your children, says Dr. Elias Aboujaoude, a Stanford University psychiatrist. “If parents are breaking their
own rules,” Aboujaoude says, “kids cannot be expected to behave differently.”
Chad Landgraf, 44, of Oklahoma, told me he was worried about how addicted his 12-year-old son and 5-year-
old daughter became when they were on their devices. So, hoping to set an example, he switched from e-books to
old-fashioned print. “When I had my Kindle or ipad open, they. didn’t know if I was reading or surfing the net,”
Landgraf says. “But at least if I have a paper copy of a book, they know I am reading. Modeling seems like the
easiest way.”
21．What may be the result of children’s using digital devices?
A．Health improvement. B．Free creation.
C．Sleep disorder. D．Good conduct
22．What does Jim Taylor suggest parents doing?
A．Killing time by using screen-based technology.
B．Forbidding kids using smartphones.
C．Setting clear boundaries for kids.
D．Restricting tech-free family time.
23．Why did Chad pick up old-fashioned print?
A．He was afraid of becoming addicted. B．He expected to be a role model.
C．He was tired of surfing the net. D．He preferred paper copies of books.
24．What can be a suitable title for the text?
A．Parenting in a digital world B．Learning to be intelligent parents
C．Using smart devices wisely D．Helping children behave themselves
【语篇解读】这是一篇说明文。孩子过度使用电子设备会带来很多危害，对于这个问题，文章对父母该如
何做提出了建议。
21．C【解析】细节理解题。根据第一段第二句“They affect sleep.”（他们影响睡眠。）可知，孩子使用电
子设备可能会导致睡眠紊乱。故选C。
22．C【解析】细节理解题。根据第三段第二句“Taylor, like many other medical and mental health
professionals, advises parents to set limits and stick to them.”（和其他许多医学和心理健康专家一样，Taylor建
议父母设定界限，并严格遵守。）可知，Jim Taylor建议父母给孩子设定清楚的界限。故选C。
23．B【解析】细节理解题。根据最后一段第二句“So, hoping to set an example, he switched from e-books to
old-fashioned print.”（因此，为了树立一个榜样，他从电子书转向了传统的印刷版。）可知，Chad捡起传统的印刷版是为了树立一个榜样。故选B。
24．A【解析】标题判断题。根据第二段“How can parents make the most of the constructive uses of screen-
based technology while minimizing its harmful effects？”（父母如何才能最大限度地发挥基于屏幕的技术的
建设性作用，同时最大限度地减少其有害影响?）可知，文章主要是讲在电子世界父母应该怎么做。故选
A。
