1 . Cars could soon be communicating with each other using 5G to make drivers aware of upcoming dangers, scientists claim. The ultra-fast mobile Internet would allow for rapid information transmission and could make drivers aware of black ice, pot holes or other dangers up ahead.

Several car manufacturers are already integrating 5G into their vehicles, including as a tool to welcome the coming of self-driving vehicles. Experts believe the high-speed connection will also improve the reliability and capability of automated vehicles to the point where they will be safer than the manual cars being driven today. They predict the number of road traffic accidents—which according to the World Health Organization (WHO) account for more than 1.3 million deaths and up to 50 million people injured worldwide every year—will drop thoroughly as a result.

Dr Dimitrios Liarokapis, a member of the research group, said: "With the help of 5G, an early warning system that alerts (给……报警）drivers is possible within the next few years. Cars that are close enough to the danger area will send warning messages to other cars around them using short-range communication technologies, but also to cars further away using 5G, fast and reliably. Then those cars will transmit the same information to cars near them and so on, forming a joined-up, multi-vehicle communication chain that stretches far and wide."

Automotive giant Ford is already working on connected cars. Earlier this year it revealed its intention to fit 80 percent of its 2020 vehicles with technology that warns drivers about upcoming road accidents, bad weather and traffic jams. The system pools data from other connected road users, emergency services and the authorities and sends it from the cloud directly to the car. Alerts are shown on the car's dashboard display warning the driver about what lies around the corner.

2 . There have been some suggestions lately calling for the end of traffic in some cities by the year 2034. In order to reduce all this traffic, governments are planning to take away one of its biggest contributors(促成物)-cars. But is this a good idea? Our first reaction may be NO-NO-NO. They're taking away our cars and how can we travel in the city daily? But when you consider the problem a little longer, you may find the plans quite sound and realistic. Here's why:

The one thing that annoys most big cities is the non-stop heavy traffic. You have to see how terrible it is to drive into a very busy city centre-London, Miami, Tokyo? I'd say it's very bad. City layouts(规划) simply aren't built to manage that many moving parts. If we allow only buses, taxis and bikes to use the road, traffic problems in large cities will be immediately solved.

If you ever go to a large city centre, you often realize the difficulty some people have with sidewalk-to-sidewalk travel. If you live in New York City, there are so many people crossing in such a small area, that it's often difficult to know what exactly is even going on. But if cities begin to do away with cars, we'd see an increase in out-of-town travelers more willing to walk about city centres in safety.

The one thing that troubles any driver is being stuck in a traffic jam in the centre of town. You move forward at a very low speed, feeling annoyed, mad, and helpless. But why go through this hassle? If we do away with cars throughout major cities, it will give drivers the chance to actually enjoy their journeys on more open roads. It's a strange thought, yes, but many drivers will tell you driving in city centres is like driving in hell(地狱).

3 . Ants keep traffic flowing by changing their behavior to meet changing conditions, according to new research.

For their experiment, researchers from the University of Toulouse and the University of Arizona focused on Argentine ants, which are only 2-3 millimeters long and frequently move from colony (栖息地) to colony depending on how far food is. Tapping into the ants' talent for fast commutes (通勤), the researchers constructed bridges between their colonies. The bridges varied in width from a fifth to three-quarters of an inch.

Then the researchers sat back and monitored the traffic. To their surprise, even when those narrower bridges were nearly overloaded, there were no 20-ant pile-ups. And traffic remained steady regardless of how crowed the bridges were because ants could adjust to the flow of road conditions.

"When crowding on the path increased, ants assessed it locally and adjusted their speed accordingly to avoid any interruption of traffic flow," the researchers said. "Moreover, ants avoided entering a crowded path and made sure the bridge was never overloaded."

The lesson for humans? The traffic problem mostly lies in our loss of the quality that the ants have. You've probably noticed it on your own commute to work. Driving is fun when there're few cars on the road-a lane-change (车道变换)here, a little acceleration there. Then traffic slows down. But some impatient drivers still constantly move between lanes.

"Traffic jams are common in human society where some people are focusing on their own personal objectives," the researchers said. "In contrast, ants share a common goal: the survival of the colony, thus they're expected to act cooperatively to get food."

The research also suggests that the ever-widening of highways may never free us from traffic jams. As long as we drive along with our own agendas, no matter how many other people are on the road, we'll always end up in a traffic jam. Indeed, less space may be a good thing. It leaves less room for personal choices and forces us to take a page from the driving handbook of ants.

4 . Los Angeles is always a popular holiday destination. To fully enjoy your travel there, you should know its food, weather, and also traffic. While driving in L. A. is similar to that in other areas, there are a few specific rules to note.

HOV lanes (车道)

On many L. A. freeways, one or more lanes at the far left are used as high-occupancy vehicle (HOV) lanes. They usually have limited access and you can only enter or exit where there is a break in the double yellow line. Most HOV lanes require a minimum of two people in the car; some require three. Vehicles towing trailers (拖车) are NOT allowed in the HOV lane, regardless of how many people are in them.

Toll (收费) lanes

On certain freeways, the HOV lanes are double-purposed as toll lanes for people driving alone who have a FasTrak, an electronic toll collection system. Therefore, you also have to have one in that lane as a HOV, which is inconvenient if you’re just visiting. FasTrak is in effect on parts of the 110 freeway between the 405 and 10 freeways, and on parts of the 10 freeway east of Downtown L. A.

Cell phones

It is against the law to talk on a cell phone while driving without using a hands-free device. Holding a cell phone to your ear while driving will land you with a ticket.

Alcohol

Driving under the influence is taken seriously in L.A. The legal blood alcohol limit is 0.08%, but you can be charged with lower levels if they show you can’t function normally. Placing an opened bottle of alcohol in the passenger area while driving (or sitting) is illegal. Any opened container of alcohol has to be transported in the trunk.

1. What do you know about HOV lanes?

A．They encourage people to share cars.

B．They are on the far right of freeways.

C．They are intended for larger vehicles.

D．They allow cars to enter over the double yellow line.

2. Which is surely against the road rules in L. A.?

A．Driving on the 110 freeway with a FasTrak.

B．Putting the cell phone in the car while driving.

C．Riding with an opened bottle of alcohol in back seats.

D．Going below the blood alcohol limit of 0. 08%.

3. Where is the text most probably taken from?

A．A traffic law.	B．A road map.
C．A guidebook.	D．A report.

5 . When bicycle-sharing company oBike pulled out of Singapore abruptly last year, it left the city with unattended bicycles everywhere. Myanmar businessman Mike Than Tun Win saw the perfect opportunity to turn trash (垃圾) into treasure. “What if these bicycles could be distributed to poor students in villages so they can cycle to school?” he thought.

Mr Than, 33, grew up in Mandalay, where he used to walk to school as a student. While traveling through rural (乡村的) areas in Myanmar over the last few years he saw things had not changed. Long lines of children in rural villages continue to walk 30 minutes to an hour just to get to school. “I thought if we could just reduce the time they take, they could spend more time studying, gain more knowledge and increase their chances of getting out of poverty (贫困),” he said.

With that, he started a movement called Lesswalk with the intention of buying bicycles from bike-sharing firms oBike and ofo-which have stopped operations in Singapore — and shipping them to Yangon. He would renew the bicycles before distributing them to teenagers and families living in rural villages in Myanmar, beginning with villages in Mandalay and Sagaing areas.

Over the last three months, the businessman has bought 10,000 bicycles in Singapore and Malaysia. He paid for 5,000 of the bicycles out of his own pocket, with other sponsors paying for the rest.

Mr Than plans to modify (修改) the bicycles so that they can better suit the needs of the children in villages, most of the time they ride around with their little brothers and sisters. I’m planning to add an extra seat at the back so that they can go to school together,” he said. He also plans to remove the digital locks and give each a new one that works better in villages.

Including the cost of shipping, modification and distribution, Mr Than thinks each bicycle might cost him around US $35 to US $40. “I might have to spend more money, but it is better that these bicycles are going to help some people rather than going to waste,” he said.

1. What's the author’s main purpose of writing the first two paragraphs?

B．To explain how to turn trash into treasure.

C．To call on more people to follow Mr Than.

D．To state the background of starting Lesswalk.

2. How does Mr Than plan to adapt the bicycles?

A．By painting them in a colorful way.

B．By adding a bright light to each of them.

B．He feels regret about what he has done.

C．He is a man with strong social responsibility.

D．He has decided to keep on working with oBike.

4. What's the best title for the text?

I like travelling and my dream of visiting Beijing, the capital city of our country, come true during the National Day holidays this year. My mother booked an one-day tour for me. On the morning of October 1st I went to Tian’anmen Square with one of my classmates , there we watched the flag-raising ceremony. As I watched the flag rising slowly, I sang the national anthem, feeling extreme proud. Several hours later, a grand military parade was held mark the People's Republic of China's 70th founding anniversary. In the afternoon we decided to go to other famous tourist attraction, like the Great Wall. When we reached the destination, it was crowded with tourists. I was glad for which those volunteers had done for little kids and elderly people . Standing on the Great wall, we couldn’t help admire the splendid scenery. This travelling, with doubt, meant a lot of to me.
