Cars could be able to "talk" to each other to warn about dangers on the roads using 5G technology in future, according to researchers.
Researchers at Glasgow Caledonian University (GCU) believe 5G may enable driverless cars to send each other messages about dangers such as ice or deep holes.
And they believe the high-speed, low -delay (低延迟的) nature of 5G will improve driverless cars to the point where they will be safer than the cars being driven today. They predict the number of road traffic accidents which cause more than 1. 3 million deaths and up to 50 million people injured worldwide every year will drop greatly as a result.
Dr Dimitrios, a member of the research group, said, “To have a better idea of what the future will look like, think of having cars that not only use sensors (感应器) to find what's around them, but also can talk to each other about safety information nearby.”
“I'm sure anyone who has had a bad experience on frozen roads would have benefited from knowing about the dangerous conditions ahead of time so they could have changed their speed or, if possible, even avoided that route (路线) altogether.”
With the help of 5G, an early warning system in vehicles will come into use within the next few years. Cars that are close enough to the danger area will pass warning messages to other cars around them using communication technologies, but also to cars further away using 5G, fast and reliably. Then those cars will send the same information to cars near them and 80 on, forming a joined-up.
5G is an exciting mobile technology, which will give a great boost to smart cities and autonomous (全自动的) vehicles among many other things.
1.Which of the following will Dr Dimitrios agree?
A.Cars can talk with drivers using 5G.
B.5G will improve the safety of car driving.
C.Massages sent by 5G will never be delayed.
D.Over 1.3 million deaths are caused by driverless cars.
2.What will cars probably do with dangerous conditions with 5G EXCEPT____________.
A.changing their speed B.turning to another route
C.getting closer to the danger area D.sending warnings to nearby cars
3.What does the underlined word "boost" in the last paragraph mean?
A.Recovery. B.Push. C.Danger. D.Fame.
4.In which part of a newspaper is the passage probably found?
A.Science and Technology. B.Entertainment. C.Life. D.Transport.

To be a good teacher, you need some of the gifts of a good actor; you must be able to hold the attention and interest of your audience; you must be a clear speaker, with a good, strong, pleasing voice which is fully under your control; and you must be able to act what you are teaching, in order to make its meaning clear.
Watch a good teacher, and you will see that he does not sit still before his class: he stands the whole time he is teaching; he walks about, using his arms, hands and fingers to help him in his explanations, and his face to express feelings. Listen to him, and you will hear the loudness, the quality and the musical note of his voice always changing according to what he is talking about.
The fact that a good teacher has some of the gifts of a good actor doesn’t mean that he will indeed be able to act well on the stage, for there are very important differences between the teacher’s work and the actor’s. The actor has to speak words which he has learnt by heart; he has to repeat exactly the same words each time he plays a certain part, even his movements and the ways in which he uses his voice are usually fixed beforehand. What he has to do is to make all these carefully learnt words and actions seem natural on the stage.
A good teacher works in quite a different way. His audience takes an active part in his play: they ask and answer questions, they obey orders, and if they don’t understand something, they say so. The teacher therefore has to meet the needs of his audience, which is his class. He cannot learn his part by heart, but must invent it as he goes along.
I have known many teachers who were fine actors in class but were unable to take part in a stage-play because they could not keep strictly to what another had written.
1.What is the text about ?
A.How to become a good teacher.
B.What a good teacher should do outside the classroom.
C.What teachers and actors could learn from each other.
D.The similarities and differences between a teacher’s work and an actor’s.
2.A good teacher ____ .
A.knows how to hold the interest of his students B.must have a good voice
C.knows how to act on the stage D.stands or sits still while teaching
3.In what way is a teacher’s work different from an actor’s ?
A.The teacher must learn everything by heart .
B.He knows how to control his voice better than an actor .
C.He has to deal with unexpected situations .
D.He has to use more facial expressions .
4.The main difference between students in class and a theatre audience is that ____.
A.students can move around in the classroom
B.students must keep silent while theatre audience needn’t
C.no memory work is needed for the students
D.the students must take part in their teachers’ plays
5.Which of the following is true?
A.Teachers have to learn by heart what they are going to stay in class.
B.A teacher cannot decide beforehand what exactly he is going to stay in class.
C.A teacher must speak louder than an actor.
D.A teacher must have a better memory than an actor.

Human beings can use language to communicate, but what about animals? How do they communicate with each other without using language? Well, different animals use different types of communication.
Sounds are one of the most common types of communication in animals. Bats usually follow sound waves to communicate. Birds communicate through their chirping(唧唧叫).Mammals generally use sounds to give calls to other members of their community and whales are good at using sound waves.
Besides sounds, facial expressions are also used by animals. For example, when dogs are angry, they show their teeth barking and raise their ears. When they’re frightened, they pull their ears behind with the mouth open. For another example, when the parent bird brings food for the baby bird, the “begging expression” can be observed on its face.
Next, gestures and body movements are also common in animals. For example, honey bees dance to communicate. A deer waves its tail to warn others of some danger coming closer. A gorilla sticks its tongue out to express anger.
Many animals communicate through smells. They give off pheromones (信息素)to express messages to other animals. Wolves, deer and insects generally use this type of communication. Even amoebas (变形虫)need to communicate and do it by giving out chemicals. The animals use this type of communication to attract others for giving birth to baby animals.
Besides the above means of communication, some animals communicate by touching each other. For example, monkeys express feelings by touching each other’s hands, and they even give hugs and kisses to express love.
1.When a dog shows its teeth barking and raises its－ears, it must be _________.
A.expressing its fear B.expressing its anger
C.begging its owner for something D.warning its owner of some danger
2.Smells are used by animals mainly to _________.
A.produce their young B.drive their enemies away
C.show their different feelings D.ask for some food
3.We can learn from the passage that _________.
A.a deer will waves its tail once it senses danger
B.most animals use their smells to attract others
C.bats are better at using sound waves than whales
D.a gorilla sticks its tongue out when it’s frightened
4.What is the main idea of the passage?
A.Sounds are the most common type of communication in animals.
B.Human beings can use language to communicate, but animals can’t.

阅读下面短文，根据其内容写一篇60词左右的内容概要。
Cultures can be different from each other in many aspects. People can eat different foods and live in different types of houses. People probably speak different languages and have beliefs and customs very different from yours. However, they can be similar in ways of connecting with each other. We sometimes call these means of communication universal languages.
Some legends hold that (据说) thousands of years ago there was a single language spoken by everyone. It is fun to think about a time when everyone may have been able to communicate in the same language though historical evidence does not support this, of course.
Today, there are thousands of languages spoken around the world. Yet, there are some means of communication that go beyond words and allow people of wildly different backgrounds to communicate and share emotions and feelings. For example, some people believe music is a universal language. There may be some scientific support for this idea, too. Experts have learned that across cultures people can recognize three common emotions in music: happiness, sadness and fear.
Another universal language that you might not have thought of is math! If you think about it now, it just makes sense. The value of “pi” is roughly 3.14159 no matter where you are. Similarly, we judge the value of something by the same mathematical calculations, no matter whether you’re counting in dollars, pounds or RMB.

It was decades ago now, but it’s still one of the most memorable conversations of my life. On a long, slow train heading north, with nothing to do but watch the rain, the man sitting opposite began trying to talk to me. Like most young women who have learned the hard way to be careful of strangers, I was unfriendly. But curiosity took over when he said that he was just bored, and liked talking.
So that’s what we did for hours and hours as the man turned out to be quite talkative. When the train finally pulled in, we didn’t change numbers. However, I still think about it sometimes on long, boring journeys, before getting a phone out and scrolling silently like everyone else. It’s a rare person who can cheerfully break the social rule about not talking to strangers without any ill intention, but life would be more interesting if more of us knew how to do it.
And that’s why I can’t be as cynical as I probably should be about “Tube Chat” campaign launched to encourage Britons to talk to each other. All anyone is being asked to do is to start a conversation they wouldn’t otherwise have had — maybe with a friend from whom they’ve been apart or a neighbor they don’t know.
Obviously, it takes more than a bit of small talk over garden fences to unite strangers together. More people live alone than did so a generation ago, and the rise in freelancing（自由职业）means more of us work alone too. We socialize increasingly through screens, sending texts instead of bothering to call.
It’s true that the “Tube Chat” campaign of a few years back failed in its attempts to make Londoners talk to each other on public transport. But even city people who would normally die rather than make eye contact with strangers still happily gather in large numbers by the Thames for the New Year’s Eve fireworks. They would get a far better view at home on television — it’s not really about the fireworks, but about being part of something communal (公共的).
There’s no guarantee (保证) that this latest campaign to reconnect will succeed wherever others have failed. But if there ever a moment to stop social disbelief it may start a fire to warm a world that sometimes feels cold. Wherever my train friend is now, ________.
1.The author introduced her train friend to ________.
A.share her most memorable but boring journey
B.express her deep regret for losing touch with him
C.show that talking to strangers can add interest to life
D.explain why people are becoming indifferent
2.The underlined word “cynical” is closest in meaning to ________.
A.doubtful B.supportive C.confused D.disappointed
3.The example of Londoners gathering for the New Year’s Eve fireworks is used to show that ________.
A.“Tube Chat”, failed in its attempts to unite strangers together
B.it’s hard to break the social rule about not talking to strangers
C.people have a wish to be socially connected by nature
D.“Tube Chat” made some difference to reconnecting people
4.Which of the following best fits in the blank in the last paragraph?
A.I hope he’s still talking B.I hope he is still as interesting
C.I will miss him forever D.I will try to get in touch with him
5.Which of the following would be the best title for the passage?
A.Keep our desire to connect. B.Avoid talking to strangers.
C.Show respect for social disbelief D.Socialize with our friends.

How fit are your teeth? Are you lazy about brushing them? Never fear: An inventor is on the case. An electric toothbrush senses how long and how well you brush, and it lets you track your performance on your phone.
The Kolibree toothbrush was exhibited at the International Consumer Electronics Show in Las Vegas this week. It senses how it is moved and can send the information to an Android phone or iPhone via a Bluetooth wireless connection.
The toothbrush will be able to teach you to brush right (don’t forget the insides of the teeth!) and make sure you’re brushing long enough. “It’s kind of like having a doctor actually watch your brushing on a day-to-day basis,” says Thomas Serval, the French inventor.
The toothbrush will also be able to talk to other applications(应用) on your phone, so developers could, for example, create a game controlled by your toothbrush. You could score points for beating monsters(怪物) among your teeth. “We try to make it smart but also fun,” Serval says.
Serval says he was inspired by his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They said “yes,” but Serval would find their toothbrush heads dry. He decided he needed a brush that really told him how well his children brushed.
The company says the Kolibree will go on sale this summer, for $99 to $199, depending on features. The U.S. is the first target market.
Serval says that one day, it’ll be possible to replace the brush on the handle with a brushing unit that also has a camera. The camera can even examine holes in your teeth while you brush.
1.Which is one of the features of the Kolibree toothbrush?
A.It can sense how users brush their teeth.
B.It can track users’ school performance.
C.It can cause users’ fear of seeing a doctor.
D.It can help users find their phones.
2.What can we learn from Serval’s words in Paragraph 3?
A.You will find it enjoyable to see a doctor.
B.You should see your doctor on a day-to-day basis.
C.You can brush with the Kolibree as if guided by a doctor.
D.You’d like a doctor to watch you brush your teeth every day.
3.What is Paragraph 5 mainly about?
A.How Serval found out his kids lied to him.
B.Why Serval thought brushing teeth was necessary.
C.How Serval taught his kids to brush their teeth.
D.What inspired Serval to invent the toothbrush.
4.What can we learn about the future development of the Kolibree?
A.The brush handle will be removed.
B.A mobile phone will be built into it.
C.It will be used to fill holes in teeth.
D.It will be able to check users’ teeth.

Researchers from the Institute for Human Ma succeeded in training a 165-pound human-like robot, called Atlas, to move across narrow blocks using a system called LIDAR.
At first sight, a robot walking across several blocks may look like a simple thing but many actions that humans can do easily are difficult for robots as heavy as Atlas.
Our joints （关节） and a natural balance system allow us to deal with different obstacles （障碍）easily. Besides, our small, narrow feet allow us to move around tight obstacles easily, or step over obstacles, while supporting ourselves.
With atlas, LIDAR uses a pulsed laser（脉冲激光器）to measure the distance between objects and this is done by the machine so it can step correctly on the blocks. It also builds a map of the area Atlas's going to travel across, and then uses a‘ path planning algorithm（算法）’to determine each step it should take. The robot is able to balance with its human-like feet and joints which give it ranges（范围）of movement.
Presently Atlas is successful with about half of its tests, according to IHMC, but the company is already working to increase that rate by improving the robot's balance and the range of movement in its joints.
Perhaps the most interesting setting for using human-like robots is outer space. The team say that when humans explore other planets, robots like Atlas could go before that to develop a habitat suitable for human beings to live in. But researchers believe they would be immediately useful in dangerous emergency situation. Their ability to walk on different types of land could make them perfect for searching a fallen building or an earthquake for people trapped, where a wheeled robot would get stuck.
1.Why is Atlas' weight mentioned?
A.To show the success of the research. B.To compare Atlas with other robots
C.To make readers interested in the topic. D.To tell how Atlas walks independently.
2.What does Atlas depend on to keep balance?
A.LIDAR. B.Its natural joints.
C.Narrow blocks. D.Its weight.
3.What can we learn about Atlas?
A.It can easily walk across different obstacles. B.It is still under improvement.
C.A pulsed laser decides each step it takes. D.It helps create a map of outer space.
4.What might Atlas do in the distant future?
A.Save lives in dangerous situations. B.Rebuild fallen houses
C.Forecast earthquake. D.Explore possible living space.

Many of us spend part of each day surrounded by strangers, whether on our daily commute (上下班往返), or sitting in park or cafe. But most of them remain just that-strangers. However, new evidence has shown that plucking up (鼓起) the courage to strike up conversation might be good for our health.
Nicholas Epley from the University of Chicago and Juliana Schroeder from the University of California are behavioural scientists. They wanted to know whether solitude is a more positive experience than interacting with strangers, or if people misunderstand the consequences of distant social connections. They found that many people feel uncomfortable and frightened talking to others and their research suggested that when we make an initial conversation “we consistently underestimate (低估) how much a new person likes us.” It seems we think that all the things could go wrong and why someone wouldn’t want to talk with us.
Their research involved an experiment with a group of Chicago commuters and found that “every participant in our experiment who actually tried to talk to a stranger found the person sitting next to them was happy to chat.” From this and other research, the conclusion is that connecting with strangers is surprisingly pleasant and it has a positive impact on our wellbeing. It’s true that talking can make you feel happier and happiness can lead to better mental health.
However, if you’re’ an introvert (性格内向者), the thought of speaking to someone new might make you anxious. But the American research found “both extroverts (性格外向者) and introverts are happier when they are asked to behave in an extroverted manner.” So maybe, if you’re a loner, it’s time to come out of your shell and make some small talk with a stranger-it could be the beginning of a new friendship.
1.What does the underlined word“solitude”in paragraph 2 mean?
A.Being calm. B.Being pleasant. C.Being alone. D.Being healthy.
2.Why might we not want to speak to a stranger?
A.Because we don’t trust a new person.
B.Because we can’t find a common topic.
C.Because we like distant social connections.
D.Because we carry a negative voice in our head.
3.What could help start a new friendship?
A.Making a small talk. B.Sitting next to a stranger.
C.Sharing personal details. D.Behaving in polite manner.
4.Which of the following is the best title for the text?
A.How to be an extrovert. B.Talking to strangers.
C.How to speak to strangers. D.Making new friends.
