The idea behind Facebook is to make us feel connected all the time.But in my research, I've found that the
truth is quite different.
Technology, it turns out, has made being alone seem like a problem that needs solving.When young people are
alone, even for a minute or two, they feel the need to connect, to get on Facebook or some other social networks
and chat.But in connecting, they often end up feeling more isolated．Why？Because by being in constant(不断
的)connection, they lose the ability to feel satisfied with their own company.
Facebook can help us keep in touch with our friends, but we too often use it instead of spending facetoface
time with them.And since we feel the need to keep up with them online, we don't have moments of loneliness
where we can collect our thoughts and learn how to be comfortable being alone.
—Sherry Turkle, Professor
Facebook connects more of us to more of our friends and family in more places than we have ever been
connected before.Yes, Facebook is a huge time sink — maybe the biggest ever.Many people post useless stuff.And
seeing too much of your friends' lives can make you jealous (嫉妒的), but it won't remove your loneliness.
Jane, a former student of mine, who is back in New York after living abroad for ten years, told me that
Facebook helps her a lot.The first time she moved back to New York from abroad, she felt disconnected from her
family and friends.Now，because of lots of photos and information updates, she knows what is happening with her
friends all the time.
In fact, if you are lonely in real life, you will be lonely online as well.
—Sree Sreenivasan, Chief Digital Officer

I had heard about VR being used in the classroom but didn't think I'd ever try it. I actually got a VR headset
(耳机)as a New Year present from my friend and started searching for apps online to see whether it could be useful
in my classroom. I soon found a free app through Google Cardboard and knew I had a lesson!
To use VR in the classroom, you need two things: a smartphone that can download (下载) the app or video,
and a headset. To find the actual videos we'd be watching, I searched through free VR apps like Orbulus, Trench
Experience VR and Cardboard. I also found hundreds of videos on YouTube. The key is to find videos made with
the 360 cameras. While they don't give the kids a 3D experience like the apps, they are still amazingly
immersive(沉浸式虚拟现实的) when viewed through the headsets.
So far we've had three lessons. I first used the headsets with my seventh grade US History class. The Trench
app allows students to “walk” through a trench (战壕) during World War Ⅰ and learn about many of the tools used
during that time. My second activity was working with the sixth grade Geography class. They used the headsets
strictly as viewers to watch a 360 video taking them through a rocky landscape. My final activity was the most
interesting one, according to the reactions (反应) of my eighth grade Civics students. I was able to find a White
House 360 tour that was made a few years ago.
For the rest of this year, I plan to continue using apps and 360 videos in my classes. Next year I'm going to
write to my boss asking for a 360 video camera so that I can begin to create my own VR field trips for the students.
5．When did the author get the idea of trying VR in her classroom?
A．When she was searching for apps online.
B．After she received a VR headset as a gift.
C．When she was having a conversation with her friend.
D．After she heard about VR being used in the classroom.
6．What does the underlined word “they” in paragraph 2 refer to?
A．The kids. B．The apps.
C．The videos. D．The headsets.
7．Which VR lesson was the most popular one among students?
A．The Civics lesson. B．The Science lesson.
C．The Geography lesson. D．The US History lesson.
8．What will the author do next year?
A．Buy a 360 video camera.

C．Take her students on more field trips.
D．Try new teaching methods in her classes.
二、七选五
It's very important to develop new technology wisely so that everyone can benefit from it. Some people
believe our technology plan should focus on building spaceships. 1. Which is the better course of action?
For those who dream of exploring outer space, the development of hightech spaceships is important. But just
one spaceship can cost billions of dollars. 2. Even the most specialized robots could be designed and built
much more cheaply than spaceships. Besides, robots could be used for practical purposes right here on Earth.
Many people who focus on future space exploration talk about solving the key mysteries of space and perhaps
even how life comes into being. 3. Robots will play many new roles in people's life in the future, but
even the robots we have now benefit us in practical ways. For example, they can work in dangerous conditions,
such as places with very high or low temperatures. They can take apart bombs (炸弹), build products, or carry out
important surgery (手术). 4.
In a word, it's clearly better to give attention, time, and money to the technological development of robots. 5.
They also benefit people in ways that are more practical than any benefit from a spaceship.
A．It is way more costly than building a robot.
B．Others believe it should focus on building robots.
C．They are less expensive to develop and more useful.
D．These are all useful things that benefit people right now.
E．Here are some of the advantages of having robots around the house.
F．Technology plays an important role in helping humans work more easily.
G．While this kind of knowledge is interesting, it is not what people need most right now.

（2022·全国·高考真题）Can a small group of drones (无人机) guarantee the safety and reliability of
railways and, at the same time, help railway operators save billions of euros each year? That is the very likely
future of applying today’s “eyes in the sky” technology to making sure that the millions of kilometres of rail tracks
and infrastructure (基础设施) worldwide are safe for trains on a 24/7 basis.
Drones are already being used to examine high-tension electrical lines. They could do precisely the same thing
to inspect railway lines and other vital aspects of rail infrastructure such as the correct position of railway tracks
and switching points. The more regularly they can be inspected, the more railway safety, reliability and on-time
performance will be improved. Costs would be cut and operations would be more efficient (高效) across the board.
That includes huge savings in maintenance costs and better protection of railway personnel safety. It is
calculated that European railways alone spend approximately 20 billion euros a year on maintenance, including
sending maintenance staff, often at night, to inspect and repair the rail infrastructure. That can be dangerous work
that could be avoided with drones assisting the crews’ efforts.
By using the latest technologies, drones could also start providing higher-value services for railways, detecting
faults in the rail or switches, before they can cause any safety problems. To perform these tasks, drones for rail
don’t need to be flying overhead. Engineers are now working on a new concept: the rail drones of the future. They
will be moving on the track ahead of the train, and programmed to run autonomously. Very small drones with
advanced sensors and AI and travelling ahead of the train could guide it like a co-pilot. With their ability to see
ahead, they could signal any problem, so that fast-moving trains would be able to react in time.
1．What makes the application of drones to rail lines possible?
A．The use of drones in checking on power lines. B．Drones’ ability to work at high altitudes.
C．The reduction of cost in designing drones. D．Drones’ reliable performance in remote areas.
2．What does “maintenance” underlined in paragraph 3 refer to?
A．Personnel safety. B．Assistance from drones.
更多资料添加微信号：hiknow_007 淘宝搜索店铺：乐知课堂C．Inspection and repair. D．Construction of infrastructure.
3．What function is expected of the rail drones?
A．To provide early warning. B．To make trains run automatically.
C．To earn profits for the crews. D．To accelerate transportation.
4．Which is the most suitable title for the text?
A．What Faults Can Be Detected with Drones
B．How Production of Drones Can Be Expanded
C．What Difficulty Drone Development Will Face
D．How Drones Will Change the Future of Railways

（天津·高考真题）Whether in the home or the workplace, social robots are going to become a lot more
common in the next few years. Social robots are about to bring technology to the everyday world in a more
humanized way, said Cynthia Breazeal, chief scientist at the robot company Jibo.
While household robots today do the normal housework, social robots will be much more like companions
than mere tools. For example, these robots will be able to distinguish when someone is happy or sad. This allows
them to respond more appropriately to the user.
The Jibo robot, arranged to ship later this year, is designed to be a personalized assistant. You can talk to the
robot, ask it questions, and make requests for it to perform different tasks. The robot doesn’t just deliver general
answers to questions; it responds based on what it learns about each individual in the household. It can do things
such as reminding an elderly family member to take medicine or taking family photos.
Social robots are not just finding their way into the home. They have potential applications in everything from
education to health care and are already finding their way into some of these spaces.
Fellow Robots is one company bringing social robots to the market. The company’s “Oshbot” robot is built to
assist customers in a store, which can help the customers find items and help guide them to the product’s location in
the store. It can also speak different languages and make recommendations for different items based on what the
customer is shopping for.
The more interaction the robot has with humans, the more it learns. But Oshbot, like other social robots, is not
intended to replace workers, but to work alongside other employees. “We have technologies to train social robots to
do things not for us, but with us,” said Breazeal.
