Self-driving vehicles will rely on cameras, sensors and artificial intelligence(AI)to recognize and respond to road and traffic conditions, but sensing is the most effective for objects and movement in the neighborhood of the vehicle. Not everything important in a car’s environment will be caught by the vehicle’s camera. Another vehicle approaching at high speed on a collision (碰撞)track might not be visible until it’s too late. This is why vehicle-to-vehicle communication is undergoing rapid development. Our research shows that cars will need to be able to chat and cooperate on the road, although the technical challenges are considerable.
Applications for vehicle-to-vehicle communication range from vehicles driving together in a row, to safety messages about nearby emergency vehicles. Vehicles could alert each other to avoid collisions or share notices about passers-by and bicycles.
From as far as several hundred metres away, vehicles could exchange messages with one another or receive information from roadside units(RSUs)about nearby incidents or dangerous road conditions through 4G network A high level of A1 seems required for such vehicles, not only to self-drive from A to B, but also to react intelligently to messages received. Vehicles will need to plan, reason, strategize and adapt in the light of information received in real time and to carry out cooperative behaviours. For example, a group of autonomous vehicles might avoid a route together because of potential risks, or a vehicle could decide to drop someone off earlier due to messages received, a foreseen crowding ahead.
Further applications of vehicle-to-vehicle communication are still being researched, including how to perform cooperative behaviour.

On March 28th, the New York Times will begin charging all but the most infrequent users to read articles online.
In a letter to readers, Arthur Sulzberger, Jr., the publisher of the paper, laid out the details of the paywall, which he said will go into effect immediately in Canada and on March 28th for the rest of the world. He called the move “an important step that we hope you will see as an investment in the Times, one that will strengthen our ability to provide high-quality journalism to readers around the world and on any platform.”
Sulzberger said that readers will be able to read 20 articles per month at no charge. Once they click on the 21st piece, however, they’ll be presented with three payment options: $ 15 for four weeks of online and mobile application access, $ 20 for access to the site and the iPad application, or $ 35 for access to everything. People who already receive the printed paper through home delivery will enjoy free and unlimited access to the Times on all platforms.
These details largely agree with earlier reports on how the paywall would work. The Times had made it clear that it did not want to imitate the total paywalls put into effect by papers such as The Times of London and Newsday, which block access to all contents unless the reader pays.
The paper also signaled that it wants to stay relevant in the social media world. According to Sulzberger's announcement, people who come to the Times site from Facebook, Twitter or from blogs will be able to read those articles even if they have gone over their monthly limit.
However, Sulzberger said that a limit will be placed on “some search engines”, meaning that after readers have accessed a certain number of articles from search engines, any further articles they access from there will be added to their monthly count. It was reported that the only search engine that will be affected this way is Google, where there will be a five-article limit. This marks a clear attempt by the Times to close what could be a giant loophole (漏洞), since so much online traffic is directed through Google. But it also presents a risk for the Times for the same reason.
Sulzberger seems well aware of the risk. “The challenge now is to put a price on our work without walling ourselves off from the global network,” he said, adding that the Times must “continue to engage with the widest possible audience.”
1.The author’s main purpose in the text is to _______.
A. describe research findings B. report a piece of news
C. make advertisements D. suggest a solution
2.Why will the Times charge their online readers?
A. It wants to stay relevant in the social media world.
B. It has too many readers coming from the other sites.
C. It is seeking new financial sources for its development.
D. It is trying a way to offer better service to its readers.
3. Who will be limited to the New York Times articles?
A. Those subscribing to the printed newspapers
B. Readers clicking through from Facebook.
C. Those using Google research engine
D. Readers paying $ 35 a month.
4.What challenge may the paywall bring to the New York Times?
A. It may bring the Times more competition with the other media
B. It may stop the Times connecting to the global network
C. It may block the readers from the other websites
D. It may result in huge drops in papers' online readership

With self-driving vehicle technology rapidly advancing, many companies are turning to autonomous robots for the last mile of the delivery process, from the store to the customer. The latest to join the trend is e-commerce giant Amazon. Following a successful eight-month test run in Snohomish County, Washington, the company’s Scout robots have been making the rounds of Irvine, California, since August 6, 2019.
The six-wheeled Scout is about the size of a large cooler with the capacity to carry small or medium-sized packages. The battery-powered vehicle, which moves at a regular walking pace, has been programmed to stay away from pedestrians, animals, and unexpected obstacles, like garbage cans. Its powerful sensors can also detect the movement of a car backing out of a driveway.
Though Amazon hasn’t revealed how Scout ensures the delivery is picked up by the right person, it most likely requires the customer to apply a unique code, texted to them before the delivery, to unlock the cargo bay. Also unclear is the number of deliveries Scout can complete before its battery needs recharging Though the initial tests are being conducted with a human in tow, the robot will be autonomous in the future. Its location however, will be tracked at all times—if someone attempts to steal Scout, Amazon employees will be instantly alerted.
While Amazon is focusing on home deliveries, food and grocery delivery company Postmates’ bug-eyed robots are currently making their rounds along the busy San Francisco streets. Also in test-mode, the robots can carry up to 50 pounds and travel 30 miles on a single battery charge.
Though the eco-friendly robots will help free our streets of bicycles, motor bikes, and large delivery trucks that typically ferry packages, they can t climb stairs or open gates, which means they can only reach consumers living the ground level. Additionally, the robots are unable to leave packages at the front door if the customers aren’t home. whether these issues get solved remains to be seen. For now, it appears that humans will still be needed to satisfy the ever-growing demand for home and office deliveries.
1.What is the right feature of the Scout robots?
A.They can be powered themselves. B.They know to avoid obstacles ahead.
C.They can run thanks to their six wheels. D.They’re big enough to carry heavy things.
2.What about Scout is still confusing to common people?
A.How long it will take to get it fully charged.
B.Why its cargo bay can open at the right time.
C.How it recognizes the right owner of the things.
D.How many deliveries it can do on a full charge.
3.What is the author’s opinion about delivery robots according to the last paragraph?
A.They are not easily available. B.They’ll replace humans soon.
C.They have some limitations. D.They won’t be well accepted.
4.What should be the best title for the text?
A.Improvements Are Being Made To Delivery robot Technology.
B.Amazon has Planned To Put A Creative Delivery Robot Into Use.
C.Eco-friendly delivery Robots Are Springing Up Around America.
D.Amazon’s delivery Robots May Soon Be Knocking At Your Door.

With self-driving vehicle technology rapidly advancing, many companies are turning to autonomous robots for the final leg of the delivery process, from the store or local distribution center to the customer. The latest to join the trend is e-commerce giant Amazon. Following a successful eight — month test run in Snohomish County, Washington, the company's Scout robots have been making the rounds of Irvine, California, since August 6, 2019.
The six-wheeled Scout is about the size of a large cooler with the capacity to carry small or medium-sized
packages. The battery-powered vehicle, which moves at a regular walking pace, has been programmed to avoid pedestrians, animals, and unexpected obstacles, such as garbage cans. Its powerful sensors can also detect the movement of a car backing out of a driveway.
To accelerate Scout's development and bring it nationwide sooner, the company has created several detailed virtual maps of American suburbs and conducted trial deliveries to homes there.
Though Amazon has not shown how Scout ensures the delivery is picked up by the right person, it most likely requires the customer to apply a unique code, texted to them prior to the delivery, to unlock the store box. Also unclear is the number of deliveries Scout can complete before its battery needs to be recharged. Though the initial tests are being conducted with a human for company, the robot will be autonomous in the future. Its location, however, will be tracked at all times ——if someone attempts to steal Scout, Amazon employees will be instantly sensed.
However, the eco-friendly robots are unable to climb stairs or open gates, which means that they can only reach consumers who live on the ground level. Additionally, the robots are unable to leave packages at the front door if the customers are not home. Whether these problems get resolved remains to be seen. For now, it appears that humans will still be needed to achieve the ever-growing demand for home and office deliveries.
1.What are many companies developing autonomous robots for?
A.Final tests. B.The so-called last mile.
C.Robots' safety. D.Delivery speed.
2.What can we infer about Scout from paragraph 2?
A.It looks like a cooler. B.It adjusts its speed accordingly.
C.Its sensors play a key role. D.It will be widely used soon.
3.What does the underlined phrase “prior to" in paragraph 4 mean?
A.Before. B.After.
C.In front of. D.Due to.
4.From which is the text probably taken?
A.A biology textbook. B.A health magazine.

“An Uber self-driving car hit and killed a woman crossing the street in Arizona,U.S.,”police said on Monday,marking the first death caused by an autonomous vehicle and a potential blow to the technology expected to transform transportation.
The ride services company said it was delaying North American tests of its self-driving vehicles,which are currently going on in Arizona,Pittsburgh and Toronto.
So-called robot cars,when fully developed by companies including Uber,are expected to thoroughly cut down on motor vehicle deaths and create billion-dollar businesses.But Monday’s accident highlighted (凸显)the possible challenges ahead for the promising technology as the cars face real-world situations involving real people.
“This catastrophic accident highlights why we need to be exceptionally cautious when testing and applying autonomous vehicle technologies to public roads,”said Edward Markey, a member of the transportation committee,in a statement.
“Elaine Herzberg,49,was walking her bicycle outside the crosswalk on a four-lane road in the Phoenix suburb of Tempe at about 10 p.m. MST Sunday when she was struck by the Uber vehicle traveling at about 65 kilometers per hour,”police said.The car was in autonomous mode with an operator behind the wheel.U.S. federal safety officials were sending teams to investigate the crash.Canada’s transportation ministry in Ontario,where Uber conducts testing,also said it was reviewing the accident.
“Uber and Waymo on Friday urged Congress to pass a law to speed the introduction of self-driving cars into the united states.However,some congressional(国会的)representatives have blocked the legislation over safety concerns,and Monday’s death could hamper passage of the bill,”congressional assistants said Monday.
1.According to the passage,which is the effect of the accident of the woman’s being killed?
A. People will be cautious while crossing a road.
B. The woman’s family will obtain a billion dollars.

For environmental reasons, Britain will ban all new petro-and diesel-powered vehicles from its roads beginning in 23 years, a government report says.
The plan, expected Wednesday, aims to start removing petrol and diesel engines in 2040. It follows a similar official statement in France and comes after the British government was ordered by the High Court to develop new plans to reduce NO2 in the air. Judges ruled that previous clean-air plans were not enough to meet European Union pollution limits in the coming years.
Britain’s government has said the poor air quality has an unnecessary and avoidable negative effect on citizens’ health, and costs up to $ 3.5 billion in annual lost productivity.
Part of the new plan involves an offer of $ 260 million to local governments to change rules where vehicle emissions(排放) are over EU standards. Ideas so far include changing road layouts, reprogramming traffic lights and charging a fee for the oldest and most polluting cars on the road.
The plan also includes $1.3 billion for government purchase of extreme-low-emission vehicles, nearly $ 130 million to improve infrastructure for electric vehicle charging stations and $ 378 million for remodeling existing vehicles.
Climate change is also a reason for the plan to get these vehicles off the road. “We can’t carry on with petrol and diesel cars,” Environment Secretary Michael Gove said. “It’s important we all prepare for a significant change which deals not just with the problems of health caused by emissions, but the broader problems caused in terms of accelerating climate change.”
Gove added that local communities are partly responsible for coming up with ways to limit emissions, including possible limitations on commuters(上下班往返者) and the addition of cleaner mass transportation options. Local leaders are called on to draw up “appropriate plans” to deal with climate challenges related to emission, he said.
1.Why does the British government decide on this ban?
A. To focus on its citizens’ health. B. To respond to the court’s request.
C. To promote solar energy in transport. D. To follow in France’s footsteps.
2.Which measure may the British government take to achieve its plan?
A. To follow in France’s footsteps.
B. Removing old and high-emission vehicles.
C. Spending some money on electric vehicles.
D. Changing the way roads are arranged.
3.What can be inferred from Gove’s words?
A. Convenient public transportation is badly needed.
B. United efforts are required to achieve the plan.
C. Vehicle emissions are the key factor in climate change.
D. Petrol and diesel cars may hold back economic progress.
4.What is the suitable title for this passage?
A. Practical ways to reduce vehicle emissions
B. The EU forces Britain to improve the poor air quality
C. Britain plans to take petrol and diesel engines off roads
D. Relationship between vehicle emissions and climate change
