Could you imagine being in a car driven by a computer, not a human? Recently, China has made a big step toward self-driving cars.

Since August, driverless taxis can run on roads in Wuhan, Chongqing and Shenzhen. Self-driving cars bring us many benefits. They use computers to sense the things around them and make better use of space. This means fewer traffic jams and better parking of cars. For disabled or blind people, self-driving cars can also help them get around more easily.

According to US Centers for Disease Control and Prevention, more than 1.35 million people are killed on roads around the world every year. Many more are injured. Self-driving cars could reduce road accidents by 90 percent and save governments a lot of money, said the website TechDim. The main cause of car accidents is human mistakes. By using computers, self-driving cars don’t make poor decisions or lose attention like humans do.

But self-driving cars aren’t perfect. If something unexpected on the road happens, self-driving cars can’t react as fast as a human driver could. Also, during weather events like heavy snow, self-driving car s would struggle (费力) to see the lines on the road. It might lead to an accident. The car’s computer system could also get hacked (非法入侵) by someone, causing it to crash or change its destination (目的地).

It’s clear that there is a lot of work to do to make self-driving cars a common and safe sight on our roads.And China is taking the lead in making this happen.

【推荐2】China's box office numbers continue to grow rapidly. It is estimated that the revenues( 收入) may pass the U. S. market's as soon as this year. However, this cinematic party could be over just as it's getting started. Some companies are working to convince consumers that the ultimate viewing experience is not on the big screen.

Instead, it's on the small ones that are already in their pockets-thanks to the technology of virtual reality.

Already,VR experience centers are popping up in major cities like Beijing and Shanghai. They give customers the opportunity to watch VR movies or play VR games for about the same price as a discount movie ticket. Online video sites, meanwhile, are also moving into the VR field. Some of them, like Youku, have launched(推出) their own VR apps and channels.

China has more than 700 million smartphone users. A large percentage of them are already more than willing to download and watch TV shows and even full-length movies on their handsets. This potentially makes them more likely to embrace VR content than Americans and Europeans.

But in fact, it's not just Chinese companies and video websites that believe VR will pull viewers away from movie theaters. International production companies that, for years, have made block busters (大片) for cinema audiences are also warning that disruptive change is around the corner.

Maureen Fan, chief executive of the Silicon Valley VR start-up Baobab Studios, after bringing her company's animated VR short Invasion to the Shanghai International Film Festival last year, concluded that the field had been evolving much more rapidly than she expected. "What I thought would take ten years has happened in one or two," she said. However, she also noted that the industry needs more people who can create great stories to move VR beyond a niche product(小众产品 ) and into the mass market. "The technology is already there. What continues to be lacking is good content," Fan said. "There's a certain amount, but we would love to see more."

1. What is the main idea of the article?
A.China's box office numbers might see a slight decline in the coming years.
B.People don't need to mind their manners when watching VR movies.
C.Movie theaters in China will be increasingly challenged by virtual reality.
D.More and more Chinese online video sites have had their own VR channels.
2. According to the article, Chinese people might be readier for VR movies than Westerners because________.
A.China's box office numbers have been growing faster than those in the West
B.more Chinese people have experienced virtual reality than Westerners
C.China has been more supportive of the development of VR than Western countries
D.more Chinese people have been watching shows on handsets than Westerners
3. According to the article, it could be hard for VR movies to move into the mass market until________.
A.VR movies become available in theaters
B.online video sites launch more VR channels
C.VR experience centers appear in smaller cities
D.there is a larger amount of good content
4. Which of the following statements would Maureen Fan probably agree with?
A.VR movies will completely replace traditional movies sooner or later.
B.Virtual reality has been experiencing an enormous development.
C.Content matters more than technology when it comes to making movies.
D.The West will catch up with China in terms of the development of VR.

文章大意:这是一篇说明文。文章主要介绍了四个由孩子发明的东西。

【推荐3】Hands-on basketball

The boy was only nine years old when he designed a “hands-on basketball”. Chris Haas had the idea when he saw his friends miss lots of baskets. His basketball has painted hands on it. The hands show you where to put your hands when you throw the ball. Today people use his invention around the world.

Wristies

At age 10, Kathryn Gregory was playing outside one day in the cold. Her wrists (手腕) began to hurt from the cold so she decided to find a way to keep both her hands and wrists warm during the winter. In 1994, she invented Wristies: fuzzy sleeves (毛绒袖子) that can be worn underneath gloves to protect your wrists from the cold. She worked with her mom to get the idea off the ground and now the product is sold worldwide.

Makin’ Bacon

Abbey Fleck was 8 years old when she noticed how much time her parents spent soaking up bacon fat (吸干培根油脂) after cooking. She realized that it might be easier to hang bacon while it cooks. That way you wouldn’t need paper towels and it would even make the bacon healthier. She then worked with her father to design a dish that hangs bacon while it cooks. Now people can see her invention in many supermarkets.

Braille

Louis Braille had an accident when he was three. The accident left him blind. At that time, it was hard for blind children to read. They had to touch raised letters. But it was difficult to tell a Q from an O, an R from a B, and so on. When he was fifteen, Louis invented an alphabet (字母表) that used raised dots. The Braille alphabet was a big success!
