2 . The United States is a nation of car owners. Ninety-five percent of households own a car, and 85 percent of people get to work in one. This lifestyle contributes to congestion on our roads and damages the environment. As autonomous vehicles begin to hit the streets over the next decade or so, it’s believed that all this will change.
Autonomous vehicles will most likely decrease the number and severity of crashes, allow cars to travel more closely together and improve cooperation between vehicles, all of which tend to reduce traffic jams and increase capacity(容量).
However, this future is not assured. To realize the full potential benefits of driverless cars, we will have to act soon to encourage a culture in which transportation is shared. Many people in the automobile industry assume that driverless vehicles will automatically be shared, but there is little evidence that this is true. Most estimates suggest that driverless cars will eventually be only slightly more expensive than traditional cars, which means they’ll be within reach of many consumers, so users are not willing to share rides.
If most people are going to buy-in to a shared-ride culture, they need to get a significant benefit. Saving a few dollars off the fare isn’t likely to promote the movement dramatically. A better benefit would be knowing that you’re going to reach your destination more quickly. The way to guarantee quick passage is to redesign our roads to give priority to ride-sharing autonomous vehicles like building priority lanes. The cost of travel will also be varied based on how efficiently a vehicle uses the roads. Autonomous vehicles carrying multiple people should get higher priority than those carrying one or none at all.
Decision-makers must push for incentives(动机) that encourage the most efficient use of our limited roadway infrastructure(基础设施). The autonomous future is rapidly approaching; it is critical that we act now, while the impacts of autonomous vehicles on traffic jams and emissions are still largely within our control.

3 . This year, new technologies will enable more drivers to take their hands off the steering wheel (方向盘)while on the road. But that doesn’t mean their cars will be fully self-driving --- that day still remains far in the future.
Automakers like General Motors (GM), Ford and Stellantis are introducing, or upgrading existing technologies. But in the words of Kay Stepper, an automated driving expert, these systems are "feet off’ and "hands off’, but they will not be "eyes off" or “mind off’.
For the time being, these systems will only be used on limited-access highways, where there are no pedestrians or bicyclists. Vehicles with this technology will be able to drive at relatively high speeds, but only in simple traffic situations.
Bryan Reimer, a researcher with the Massachusetts Institute of Technology’s AgeLab, said it will be decades before people can buy truly self-driving cars in which humans ride as passengers.
Still, the technology that will be rolled out by the major automakers this year will do more than most so-called Advanced Driver Assistance Systems, or ADAS, do now.
GM’s Super Cruise system allows drivers to completely let go of the steering wheel while driving on selected highways. It was introduced in 2017 on the Cadillac CT6 sedan, which was discontinued last year. An improved version is coming this year on the Cadillac Escalade SUV and the Cadillac CT4 and CT5 sedans.
Super Cruise only works on highways that have been previously laser-mapped in three dimensions. GPS positioning and the vehicles, radar sensors (传感器)and cameras are used to enable drivers to unhand -- and unfoot — all the controls.
Drivers still need to pay attention, however. A camera in the car makes sure the driver is looking at the road at all times. If the driver looks away from the road for more than a few seconds, the system will stop working.

4 . I've lived in big cities. And I was often woken at night and frequently concerned by the almost constant sounds of car and truck engines. I now live in the middle of the woods.
So I was excited when hearing about the Spanish city that has prevented cars from running. It seemingly means I could have everything that a city offers museums and culture, walking to get groceries or delicious coffee, a quick subway or bus ride to work —and peace and quiet. It sounds like that's what people in Pontevedra got after this city carried out its leader Lores' order of changing 75 acres of this city's historic center into a pedestrian-only place.
Formerly, the area had been filled with cars. People tried to get in and out of the area as quickly as they could. Cars would get stuck in the area when they tried to cross the city, while others circled endlessly looking for a parking space, which led to upset for drivers and plenty of noise for pedestrians and residents.
Later the area was rebuilt with beautiful stones and returned to pedestrians. Nearly three-quarters of what were car journeys are now made on foot or by bicycle. Air becomes much cleaner. As a result, the population of central Pontevedra is obviously increasing after it has attracted 12.000 new residents from nearby towns to live there.
Considering the negative health effects of pollution, it makes sense to get rid of cars from at least some parts of urban areas. The good news is that Pontevedra isn't the only one to expand car-free areas. Dublin, Santa Monica and Burlington have pedestrian-only areas, too. These cities' great changes will probably positively shape many other leaders' decisions on city planning.

5 . Why I Love Cycling
One of the first things I did when I moved to a new city was to hire a bike. Why?
Besides, I soon discovered plenty more benefits to cycling. A bike means that fewer places, especially in a small city like the one where I live now, feel far away. For example, cycling to work takes me half the time that it would to walk.
Of course, there are obvious health benefits of cycling—a bit of extra movement as part of your daily routine can help you keep fit and healthy. Cycling on my way to work also makes me feel more energetic in the mornings.
A.However, be careful when cycling. |
B.A bike means more happy time with your friends. |
C.I have to learn to ride safely on the right of the road. |
D.Importantly, cycling also helps to reduce your carbon footprint. |
E.Riding a bike also means you’re not restricted by bus timetables. |
F.And sometimes city roads are difficult or unpleasant for cyclists. |
G.Seeing a city by bike is ideal for settling in and learning your way around. |
A.By car. | B.By bus. | C.On foot. |
