Electric vehicles (电动汽车) or EVs recently have become more and more popular. Technological improvements, especially batteries, make EVs rather than gas cars become more people’s first choice.

Mueller, an expert in studying cars, explains why they are the future of cars. He writes, “I think EVs are the future. They have better torque (扭转力), acceleration (加速) and better control.”

Best of all, you never have to visit a gas station. Every morning your car is charged (充电) and ready to go. And if you are worried about miles they can cover, that’s not necessary. Almost all trips can be done in an EV with a proper battery. And fast chargers (充电器) along the way make it possible to do longer road trips if necessary.

Besides, it’s clean technology: a traditional gas car causes more than twice as carbon (碳) pollution as an EV. Even in places that get almost all of their electricity from burning coal (煤), an EV still pollutes less than a typical traditional gas car. Supposing a 10-year service life, a traditional car will let out 66,000 pounds more carbon pollution than an electric vehicle.

Human science technology is always moving forward. However, some challenges still remain about EVs. According to the present situation of EVs, scientists and researchers still have a long way to go.

1. EVs have become more popular than gas cars thanks to ________.
A.technological improvementsB.social development
C.lower pricesD.beautiful appearance
2. It’s unnecessary to worry about miles EVs can cover because of proper batteries and ________.
A.better torqueB.accelerationC.better controlD.fast chargers
3. What can we know from the 4th paragraph?
A.EVs are always cleaner than gas cars.
B.Electricity is from burning coal in China.
C.A gas car causes less pollution than an EV.
D.A traditional car lets out 6,600 pounds of carbon a year.
4. What can be the best title for this text?
A.The Future of EVs in ChinaB.EVs and Environmental Protection

【推荐2】What would the world be like if cars could drive themselves?Imagine seeing an empty car passing by on its way to pick up its owner, or a car full of passengers who are reading, listening to music or even sleeping. But none of them is worried about the road ahead.

Well, all of these could be the future of driving. There are several companies, for example, Google, working on driverless cars. So far, no Google self­driven car has got a traffic ticket, but some of them have been in accident when other cars hit them.


These cars are now still in the testing stages. If the tests are successful, these electric, self­driven cars could be available very soon. But how is it possible for a car to drive itself?Cars already have many features allowing them to take the place of drivers during certain situations. Some features include cars being able to park themselves, or slow down when they notice other cars close by. They can also control the speed if there are dangerous conditions.

Scientists believe that with the help of wireless signals, cameras and GPS, it is possible to create a safe self­driven car very soon.

The cause of deadly road accidents is usually careless drivers or dangerous conditions. The self­driven car may be able to stop this. However, some people do not like the idea. American lawyer Whit Drake, for example, doesn't believe these cars are safe. He thinks that technologies can also be mistakes.

1. The main purpose of the first paragraph is to ________.
A.get readers to pay attention to road safety
B.tell readers the danger of self­driven cars
C.ask readers to keep away from heavy traffic
D.make readers be interested in self­driven cars
2. The testing self­driven cars need ________ to run.
A.solar energyB.water
C.electricityD.coal
3. From the passage, we know that the testing self­driven cars can already ________.
A.stop any accident on the road
B.turn around when getting near other cars
C.control the speed in dangerous situations
D.park themselves with the help of the drivers
4. Which is NOT helpful to make the self­driven cars run safely according to the passage?
A.E­reading.B.Wireless signals.
C.Cameras.D.GPS.
