Ⅰ.阅读理解
Laptop computers are popular all over the world.People use them on trains and airplanes, in airports and hotels.These laptops connect people to their workplaces.In the United States today, laptops also connect students to their classrooms.
Westlake College in Virginia will start a laptop computer program that allows students to do schoolwork anywhere they want.Within five years, each of the 1,500 students at the college will receive a laptop.The laptops are part of a $10 million computer program at Westlake, a 110-year-old college.The students with laptops will also have access to the Internet.In addition, they will be able to use e-mails to “speak” with their teachers, their classmates, and their families.However, the most important part of the laptop program is that students will be able to use computers without going to computer labs.They can work with it at home, in a fast-food restaurant or under the trees — anywhere at all!
Because of the many changes in computer technology, laptops used in higher education, such as colleges and universities, are workable.As laptops become more powerful, they become more similar to desktop computers.In addition, the portable computers can connect students to not only the Internet, but also libraries and other resources.State higher-education officials are studying how laptops can help students.State officials are also testing laptop programs at other universities, too.
At Westlake College, more than 60 percent of the staff use computers.The laptops will allow all teachers to use computers in their lessons.As one Westlake teacher said, “Here we are in the middle of Virginia and we're giving students a window on the world.They can see everything and do everything.”

China has recently published its first artificial intelligence (AI，人工智能) textbook for high school students in Shanghai to start AI lessons.Forty high schools around the country have become experimental bases for exploring AI education.
The book, Fundamentals of Artificial Intelligence, includes the history of AI and how the technology can be used in areas such as facial recognition, public security and auto driving.
Peng Yu is a teacher at the High School Affiliated (附属) to Shanghai Jiao Tong University.He took part in editing the textbook and said it would give guide to students.He said, “The book has a good introduction to the area so that students can decide if they want to further study AI at college.Students can also find out what they need to learn if they are interested in studying AI.For example, they have to learn Maths because it is the fundamental basis of AI.”
Peng said AI has improved the interest of many high school students already, but he still feels that they can learn much more by taking part in project-based learning programs.Peng is sure that everyone should learn some basic knowledge about AI because it will be part of our everyday lives.It is reported that China needs 5 million AI teachers to keep up with development in the future.

Ask anyone who lives in an apartment in a packed city and they'll likely tell you space is among their biggest problems.Those living in even smaller rooms know the headache all too well.Some even pay money each month for storage as a result just to make more room.
Boston-based company Ori is out to solve those problems with a system that uses robotics and apartment furniture to change small spaces in seconds.
The company's new system is also called Ori, which is named for the Japanese word “origami”， the art of folding (折叠) paper.The new system makes your furniture change your small space from a living room into a bedroom and even a workspace with the push of a button (按钮)．
Ori came from MIT's Media Lab, which works to help companies to create a better future for people.The company is working with developers Boston Properties, Skanska and Samuels Associates to put the furniture in high-end apartments in Boston.It is working with designer Yves Béhar on the furniture designs.
The Boston models are being rented (租用) on Airbnb, an online company offering people rentals, so Ori can collect information about what users think of the system and improve it in the future.The system will be put on the market in the near future, said Larrea, founder and CEO Hasier Larrea.
All of Ori's product is made in the US, and Larrea said the furniture is actually more expensive to make than the robotics.Assembly (装配) is simple — the unit can be put together in just a day, Larrea explained.The most difficult thing for this MIT team was making the system feel and look personal.
“We are robotics people and have created these amazing robots with amazing abilities，” he said.“But when you bring a system into a home, it can't look like a robot.”

A．By helping to keep his house tidy.
B．By using a robot to clean his furniture.
C．By letting his rooms serve different purposes.
D．By making a robot do daily work for him.

A．It is now being tested.
B．It has a few disadvantages.
C．It was designed by Yves Béhar.
D．It has just come onto the market.

8．What is the company making an effort to do now
A．Develop better robots.
B．Shorten the assembly time.
C．Cut down on its product's costs.
D．Make its product more human-friendly.

The company's new system is also called Ori, which is named for the Japanese word “origami”， the art of folding (折叠) paper.The new system makes your furniture change your small space from a living room into a bedroom and even a workspace with the push of a button (按钮)．
Ori came from MIT's Media Lab, which works to help companies to create a better future for people.The company is working with developers Boston Properties, Skanska and Samuels Associates to put the furniture in high-end apartments in Boston.It is working with designer Yves Béhar on the furniture designs.
The Boston models are being rented (租用) on Airbnb, an online company offering people rentals, so Ori can collect information about what users think of the system and improve it in the future.The system will be put on the market in the near future, said Larrea, founder and CEO Hasier Larrea.
All of Ori's product is made in the US, and Larrea said the furniture is actually more expensive to make than the robotics.Assembly (装配) is simple — the unit can be put together in just a day, Larrea explained.The most difficult thing for this MIT team was making the system feel and look personal.
“We are robotics people and have created these amazing robots with amazing abilities，” he said.“But when you bring a system into a home, it can't look like a robot.”
5．What is troubling the people mentioned in the first paragraph
A．Storage units in the city are getting smaller.

6．How can the company Ori help a user
A．By helping to keep his house tidy.
B．By using a robot to clean his furniture.

Teachers say that the digital age has had a good influence and a not-so-good influence on American teenagers.More than 2,000 middle school teachers took an online survey.Researchers also spoke with teachers in some groups.Most teachers think the Internet and digital search tools have had a mostly positive influence on their students' research habits and skills.But at the same time, some teachers also point out some problems in teenagers' using digital search tools.
The Pew Internet Project did the survey with the College Board and the National Writing Project.Judy Buchanan is the director of the National Writing Project and a co-writer of the report.She says digital search tools are helping students learn more, and learn faster.“Both teachers and students really welcome these tools because they make learning exciting.And the goal is to really help students become creators of something meaningful, and not just users of the online information.”
But one problem the survey found is that these technologies make teenagers have short attention spans (持续时间)．As there is lots of information about different subjects on the Internet, teenagers' attention is easily drawn away from their research.
Another problem the survey found is that many students trust the information they find on the Internet too much.Judy Buchanan says these students have not developed the skills to judge the online information.They need to learn a lot to tell if the information is believable.It's something that really has to be paid attention to.
One more problem the survey found is something that might not seem like a problem at all: being able to quickly find information online.Many students think “doing research” now means just doing a quick search on the Internet.Teachers say the result is a drop in the wish and ability of their students to work hard to find answers.That is, they are depending too much on search engines and do not make enough use of printed books or research libraries.
Many teachers also say that the Internet makes it easy for students to copy work done by others instead of using their own abilities.
语篇解读：本文是一篇说明文。文章主要介绍了数字搜索工具给青少年带来的一些帮助和问题。

After leaving college, Lisa entered a company and began to work there. The work wasn't very tiring. Though the pay wasn't very high, Lisa loved working there. Sadly, about ten years later, a devastating (毁灭性打击) blow came to her company, and over a two-year period the business dropped out of site. Lisa lost her job as a result.
At that time, Lisa had already got married and had a five-year-old son. And her husband David, didn't make enough money to support the whole family. Lisa began to feel guilty that she wasn't contributing any kind of income after losing her job. But she had faith that everything would be okay.
Lisa began to hunt for a job. However, finding work was difficult for her as she didn't hold an important position in her former company. It felt as though she would never be called for a job interview.
One day, Lisa came across her former colleague Jenny. They greeted each other and then began to talk. Through talking with her, Lisa found that Jenny had already found work in a large company.
Lisa wasn't very surprised. She knew Jenny had been learning new languages after work. As far as she knew, Jenny could speak French, Spanish and Italian. Besides learning new languages, Jenny also spent much time improving other skills. When once advised doing that too, Lisa said she didn't have to. She didn't think that she'd lose her job one day.They didn't talk for long as Jenny was going to meet a client.
“Goodbye, Lisa. I wish you good luck，” with these words, Jenny left.
Lisa watched Jenny walk away. She looked so confident. Lisa really regretted not learning anything new after work.
“If I have learned new things as Jenny, I must have already found new work，” said Lisa to herself.
That day after coming back home, Lisa talked with her husband. She told him about Jenny's new work.
“Honey, why not follow Jenny's example It's never too late to learn something new. So why not start now？” said her husband.
“You're totally right, honey，” said Lisa.

Paragraph 1：
That night, Lisa thought about what she should do next. Since it was difficult to find a good full-time job, she decided to find a part-time job first. Luckily for her, a French couple in her neighborhood were looking for someone to look after their one-year-old son. Lisa applied for the job and she got it. She knew it was a good opportunity for her to learn French. So she began to learn this language and tried her best to speak French with the couple.
Paragraph 2：
Besides learning French, Lisa also tried to improve her computer skills. About one year later, she tried hunting for a job again. She sent out applications and a few days later, she got replies, asking her to have job interviews. Finally, Lisa got a job she truly wanted. Though Lisa had managed to find a job, she knew she shouldn't stop learning new things. She would keep learning so that she would find new work easily if she lost her job again. That was an important lesson she had learned from Jenny.UNIT 4 课时跟踪检测（四） 阅读写作融会练

How many phone numbers can you remember by heart It's probably fewer than you would like.Actually, you are not alone.Out of more than 1,000 Americans who were surveyed, more than half said that they couldn't recall the phone numbers of their friends and neighbours.In their eyes, there is no point in filling their heads with phone numbers if they are all stored in smart phones that are with them almost all the time.
In fact, most people are suffering from a sort of digital amnesia (健忘)．More than 90% of those surveyed agreed that they used the Internet as an online of their brains.Rote memorization (死记硬背) was once an important part of modern education, but we just need a click or slide now.That's making us worse at remembering things.
Researchers found that when people expected to use the information online, they were less likely to remember actual facts, but more likely to remember how to find them.As a result, we are already becoming ones with our computer tools, growing into interconnected systems that remember less by knowing information than by knowing where the information can be found.
However, some believe it isn't necessarily a bad thing — maybe it gives them more chances to think through things.We certainly acquire more knowledge now than ever, even if it isn't all stored in our brains.
Even so, I still believe that there are more risks to this new world of memory beyond losing our ability to recall some information such as who the 15th President was.That kind of information may always be a click away, but the important things are personal ones, like the way your parents smiled at your wedding.It's harder to recall or find online.If you're relying on yourself to keep track of those memories, they will be much more meaningful.
语篇解读：本文是一篇说明文。文章介绍了很多人因依赖网络或手机来存储、记忆信息导致其对基本信息的记忆力下降，作者对此现象表示担忧。
4．Paragraph 1 is mainly used to ________.

7．What's the author's attitude towards people's memories now
A．Worried. B．Optimistic.
C．Disappointed. D．Confident.

Researchers from the University of Oxford did a study on 12,000 UK adolescents, and found that family, friends and school life all had a greater effect on their well-being than social media.
The study looked into whether teenagers who use social media more have lower life satisfaction, or whether teenagers with lower life satisfaction use more social media.Past research on the relationship between screens，technology and children's health has often been contradictory.Andrew Przybylski and Amy Orben, from the Oxford Internet Institute at the University of Oxford, said it was often based on limited evidence which does not give the full picture.
Their study concluded that most links between life satisfaction and social media use were “trivial”， accounting for less than 1% of a teenager's well-being.Prof Przybylski, director of research at the institute, said, “99.75% of a person's life satisfaction has nothing to do with their use of social media.” The study, which took place between 2009 and 2017, asked thousands of 10- to 15-year-olds to say how much time they spent using social media on a normal school day and also rate (评定) how satisfied they were with different aspects of life.They found more effects of time spent on social media in girls, but they were tiny.
Przybylski added，“Parents shouldn't worry about time on social media.We are too focused on time but we need to retire this notion (观念) of screen time.The results are not showing evidence for great concern.”
However, Dr Max Davie, officer for health improvement at the Royal College of Paediatrics and Child Health, said, “We suggest that families continue to avoid screen use for one hour before bed, since there are other reasons besides mental health for children to need a good night's sleep.”
语篇解读：本文是一篇说明文。文章主要介绍了一项研究表明，社交媒体的使用对青少年的生活满意度影响很小。
8．What did the researchers try to find out
A．How strongly social media influences teenagers' happiness.
B．Why today's teenagers are so dependent on social media.
C．How much time teenagers spend using social media.
D．What makes teenagers satisfied with their lives.
解析：选A 细节理解题。根据第二段中的“The study looked into whether teenagers who use social media more have lower life satisfaction, or whether teenagers with lower life satisfaction use more social media.”可知，这项研究是为了调查社交媒体的使用会在多大程度上影响青少年的生活满意度。
9．What does the underlined word “it” in Paragraph 2 refer to
A．The new study. B．Social media.
C．The past research. D．Life satisfaction.
解析：选C 代词指代题。根据画线词前的“Past research on the relationship between screens, technology and children's health has often been contradictory.”以及画线词后的“based on limited evidence which does not give the full picture”可知，画线词it指代的是之前的研究。
10．Which of the following statements would Dr Max Davie agree with
A．Sleep influences teenagers' happiness most.
B．Parents need to notice their kids' online time.
C．Social media use has no influence on teenagers' life.
D．Teenagers' daily life is badly affected by screen time.
解析：选B 推理判断题。根据最后一段中的“We suggest that families continue to avoid screen use for one hour before bed”可知，Dr Max Davie建议父母仍然要注意孩子们的上网时间，避免睡前一小时看屏幕。
11．What is the text mainly about
A．The relationship between social media and children's health.
B．The importance of reducing teenagers' screen use.
C．The measure to reduce risks from social media.
D．The tiny influence of social media on teenagers.
解析：选D 主旨大意题。 通读全文可知，本文主要介绍了一项研究表明，社交媒体的使用对青少年的生活满意度影响很小。

Henry started his teddy bear craft-making hobby when he was only 9 years old.Now a teen, his one-of-a-kind collection has grown into thousands, but you won't find his bears on the shelf at home.His mission of kindness has the only purpose of donating his creations to put a smile on the faces of sick children and lift their spirits.
The young boy's work began one day when he was shopping with his mother.He asked if he could buy a few presents for sick children in hospitals.His mother had to refuse because the family, which included nine children, could simply not afford the extra cost.Henry told his mother not to worry — he would make the toys himself.
“I hadn't sewed (缝纫) anything before.In the beginning, it took me a lot of practice，” Henry recalled.
He borrowed his mother's sewing machine and got straight to work.He learned to create the toy animals by trial and error, using the Internet for instructions.It took him five hours to make his first bear, which he described as “a simple, ugly bear”．With much practice and effort, he was able to cut his time down to one hour per bear, and he began creating unique, bright-coloured bears that kids love to hug.
Throughout his youth, while most other children were playing video games or skateboarding, Henry was working on a sewing machine, making stuffed animals.What drives his hard work is seeing firsthand how a child changes when they are gifted a teddy bear.Each child's eyes light up with joy, and for a moment, they forget their illness.
“They smile, and some hug me.It makes their whole day better，” said Henry, describing how children typically react when he hands them a toy bear.He believes each bear inspires a sense of hope in the receiver.

Paragraph 1：
After his story was aired on TV, Henry started his own organization.People around the world have donated money to his organization to assist him on his teddy bear mission.With these gifts, he now donates toys to children in need all over the world.His bears have become so popular that some are auctioned off (拍卖), with the money going toward offering children with cancer and their families a much-needed escape from their medical battles.
Paragraph 2：
Then the young boy launched his own channel on the Internet. It was aimed to instruct others on how to sew so that they too could be creative.Henry said he believed that kindness could change the world.Henry is considered as a true hero for uplifting sick children and easing the fear and anxiety of people in need.His action is a great example of the value of kindness.As he demonstrates, one small idea can make a great difference.UNIT 4 课时跟踪检测（五） 主题阅读拓展练

How many phone numbers can you remember by heart It's probably fewer than you would like.Actually, you are not alone.Out of more than 1,000 Americans who were surveyed, more than half said that they couldn't recall the phone numbers of their friends and neighbours.In their eyes, there is no point in filling their heads with phone numbers if they are all stored in smart phones that are with them almost all the time.
In fact, most people are suffering from a sort of digital amnesia (健忘)．More than 90% of those surveyed agreed that they used the Internet as an online of their brains.Rote memorization (死记硬背) was once an important part of modern education, but we just need a click or slide now.That's making us worse at remembering things.
Researchers found that when people expected to use the information online, they were less likely to remember actual facts, but more likely to remember how to find them.As a result, we are already becoming ones with our computer tools, growing into interconnected systems that remember less by knowing information than by knowing where the information can be found.
However, some believe it isn't necessarily a bad thing — maybe it gives them more chances to think through things.We certainly acquire more knowledge now than ever, even if it isn't all stored in our brains.
Even so, I still believe that there are more risks to this new world of memory beyond losing our ability to recall some information such as who the 15th President was.That kind of information may always be a click away, but the important things are personal ones, like the way your parents smiled at your wedding.It's harder to recall or find online.If you're relying on yourself to keep track of those memories, they will be much more meaningful.
4．Paragraph 1 is mainly used to ________.
A．serve as the background
B．introduce the topic
C．explain new research
D．show some data to readers
5．What's the main cause of people's suffering from digital amnesia
A．Dealing with too many things.
B．Seldom thinking about questions.
C．Relying on the Internet too much.
D．The changes of their memories.
6．It can be learned from the passage that ________.
A．over 90% people are suffering from digital amnesia
B．people can gain knowledge more easily than before
C．rote memorization no longer exists in modern life
D．People find it hard to remember how to find information
7．What's the author's attitude towards people's memories now
A．Worried. B．Optimistic.
C．Disappointed. D．Confident.

Researchers from the University of Oxford did a study on 12,000 UK adolescents, and found that family, friends and school life all had a greater effect on their well-being than social media.
The study looked into whether teenagers who use social media more have lower life satisfaction, or whether teenagers with lower life satisfaction use more social media.Past research on the relationship between screens，technology and children's health has often been contradictory.Andrew Przybylski and Amy Orben, from the Oxford Internet Institute at the University of Oxford, said it was often based on limited evidence which does not give the full picture.
Their study concluded that most links between life satisfaction and social media use were “trivial”， accounting for less than 1% of a teenager's well-being.Prof Przybylski, director of research at the institute, said, “99.75% of a person's life satisfaction has nothing to do with their use of social media.” The study, which took place between 2009 and 2017, asked thousands of 10- to 15-year-olds to say how much time they spent using social media on a normal school day and also rate (评定) how satisfied they were with different aspects of life.They found more effects of time spent on social media in girls, but they were tiny.
Przybylski added，“Parents shouldn't worry about time on social media.We are too focused on time but we need to retire this notion (观念) of screen time.The results are not showing evidence for great concern.”
However, Dr Max Davie, officer for health improvement at the Royal College of Paediatrics and Child Health, said, “We suggest that families continue to avoid screen use for one hour before bed, since there are other reasons besides mental health for children to need a good night's sleep.”
8．What did the researchers try to find out
A．How strongly social media influences teenagers' happiness.
B．Why today's teenagers are so dependent on social media.
C．How much time teenagers spend using social media.
D．What makes teenagers satisfied with their lives.
9．What does the underlined word “it” in Paragraph 2 refer to
A．The new study. B．Social media.
C．The past research. D．Life satisfaction.
10．Which of the following statements would Dr Max Davie agree with
A．Sleep influences teenagers' happiness most.
B．Parents need to notice their kids' online time.
C．Social media use has no influence on teenagers' life.
D．Teenagers' daily life is badly affected by screen time.
11．What is the text mainly about
A．The relationship between social media and children's health.
B．The importance of reducing teenagers' screen use.
C．The measure to reduce risks from social media.
D．The tiny influence of social media on teenagers.

Henry started his teddy bear craft-making hobby when he was only 9 years old.Now a teen, his one-of-a-kind collection has grown into thousands, but you won't find his bears on the shelf at home.His mission of kindness has the only purpose of donating his creations to put a smile on the faces of sick children and lift their spirits.
The young boy's work began one day when he was shopping with his mother.He asked if he could buy a few presents for sick children in hospitals.His mother had to refuse because the family, which included nine children, could simply not afford the extra cost.Henry told his mother not to worry — he would make the toys himself.
“I hadn't sewed (缝纫) anything before.In the beginning, it took me a lot of practice，” Henry recalled.
He borrowed his mother's sewing machine and got straight to work.He learned to create the toy animals by trial and error, using the Internet for instructions.It took him five hours to make his first bear, which he described as “a simple, ugly bear”．With much practice and effort, he was able to cut his time down to one hour per bear, and he began creating unique, bright-coloured bears that kids love to hug.
Throughout his youth, while most other children were playing video games or skateboarding, Henry was working on a sewing machine, making stuffed animals.What drives his hard work is seeing firsthand how a child changes when they are gifted a teddy bear.Each child's eyes light up with joy, and for a moment, they forget their illness.
“They smile, and some hug me.It makes their whole day better，” said Henry, describing how children typically react when he hands them a toy bear.He believes each bear inspires a sense of hope in the receiver.

I went to a small and poor elementary school.I remember the first time a computer showed up in class.It was 5th grade.It was the only computer in my school.This was the 80s and it was a $2,600 machine.
Before I discovered computers, I took typing class on old typewriters and I was the kid in class that repaired the typewriters.I remember spending hours trying to figure out what each typewriter needed to fix a stuck key.I was also the Audio/Visual geek (狂热的人)．This meant I was the only one in the class who can thread (穿过) film onto the projector.
Anyway, when this computer showed up, I immediately opened it.I had to see what was inside.This totally freaked_out the teacher but it seemed clear I wasn't going to break it.I quickly learned how to get out of educational games and write things in BASIC.This was all in 5th grade.
I and my 5th grade teacher stayed in touch until her passing.I honestly don't know what I'd be doing if she hadn't done something extraordinary.She let my father and me took the computer home.I'd spend the weekend programming, reading the massive notebooks.This was a $2,000＋ computer in the middle of the 80s — the pride of the school — and they let me take it home.A year later, I came home from school one day and the family car was gone and there was a Cormmodore 64 left in its place.My parents had sold the car and bought a Commodore.
Now, I think about this crazy journey.I am standing on the shoulders not only of computer science giants, but also heroes like my parents and my 5th grade teacher.Thanks, Mrs Hill, for introducing me to computers even though you were breaking rules.Thanks, Mom and Dad, for bringing a computer home even when there wasn't money for one.
