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.

【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.

Four Ordinary People Flew into Space
A group of four ordinary people (普通人) flew into space in the first space mission (任务) with no professional astronauts. The four remained in space, circling the Earth for three days. Though this was the first “all amateur (业余者)” flight, it’s clear that the members had a lot of knowledge and experience which was helpful. They had also had a quick astronaut training course.
Plane travel used to be very expensive, but now many people may afford it. It opens up space for ordinary tourists.

【推荐2】To us, it seems so natural to put up an umbrella to keep the water off when it rains. But in fact the umbrella was not invented as protection against the rain. Its first use was as a sunshade (遮阳伞).
Nobody knows who first invented it, but the umbrella was used in very ancient times. Probably the Chinese were the first to use it, back in the 11th century BC.
We know that the umbrella was used in ancient Egypt and Babylon as a sunshade. And there was a strange thing that connected with its use: it was a symbol of honor and power. In the Far East in ancient times, the umbrella was allowed to be used only by those in the upper class or by royal people such as kings or queens.
In Europe, the Greeks were the first to use the umbrella as a sunshade. The umbrella was in common use in ancient Greece, but it is believed that the first people in Europe to use the umbrella as protection against the rain were the ancient Romans. During the Middle Ages in Europe, the use of the umbrella almost disappeared. Then it appeared again in Italy in the late 16th century. And again it became a symbol of power.
The umbrella has not changed much in style during all the time, though it has become much lighter in weight. It wasn’t until the 20th century that the umbrellas for women began to be made in all kinds of colors.

【推荐3】Beginning in the middle of the 20th century, a few people were worried about polluting the earth’s water and air, but most people did not change their way of life. Instead, to drive more and more cars and trucks, and to cut down trees.
By the year 2200, the earth’s water was completely polluted. Scientists said that in the future there might be too many people on the earth. People don’t drink enough water.
So, by the year 2300, there were so many people that food became scarce (缺乏的). There was no water to grow food and all of the fish in the lakes and seas died because of pollution. Terrible wars (战争) broke out between the rich and the poor.
By the year 2400, the air was too polluted for humans to breathe. So we had to leave earth. But only the rich were able to leave. Where did we go? Nowhere. And everywhere. You see scientists did not find another safe planet, so now we must travel around the universe in our spaceships.
