Even as Google plans to test its fleet (车队) of self-driving cars on public roads this summer, its business model remains a bit of a mystery. By 2025, as many as 250,000 self-driving vehicles could be sold each year globally, according to a study by an industry research firm.
“Vehicles that can take anyone from A to B at the push of a button could transform mobility for millions of people,” said Chris Urmson, director of Google’s self-driving car project. For now, Google has no plans to sell any of its self-driving cars. They are strictly for research. But they will hit public roads this summer near Google’s headquarters in Mountain View, California. Previous testing has taken place only on closed courses.
The cars are built to operate without a steering wheel, accelerator (油门) or brake pedal. “Our software and sensors do all the work,” Urmson said. “The vehicles will be very basic — we want to learn from them and adapt them as quickly as possible — but they will take you where you want to go at the push of a button.” The prototype (雏形) is the first of a 100-car fleet the tech giant is building.
In the long run, Urmson sees a future of safer roads — the majority of auto accidents are caused by human error — and fewer traffic jams. Robotic cars could also shuttle people who can’t drive because of age or illness.
Google has said that self-driving cars could launch new business models in which people buy the use of vehicles they don’t own. The company has already tested other types of self-driving cars on public streets, including modified Lexus sport-utility vehicles, under a special permit program by the California Department of Motor Vehicles that requires a human driver at the controls.
The state has issued six other companies permits to operate such cars, including Delphi, Mercedes-Benz, Volkswagen, Tesla, Bosch and Nissan. The vehicles that will be tested on open roads this summer will have removable steering wheels, accelerators and brake pedals to allow “safety drivers” to take control if needed.

Many Americans buy an evergreen tree for Christmas. They put the tree in their home and hang small lights and colorful objects on it. The evergreen is usually a pine or a fir tree (冷杉树). It remains green during the cold, dark months of winter in the northern part of the world. So it is a sign of everlasting life.
Early long ago, Romans probably planted evergreen trees during a celebration in honor of their god of agriculture. The Christmas tree may have developed from a popular play performed hundreds of years ago in what is now Germany. Traditionally, the play was on December 24th, the day before Christmas. The play was about the first people that God created—Adam and Eve. People put apples on an evergreen tree to represent the tree of knowledge in the Garden of Eden.
By the year 1600, some Germans began bringing evergreen trees into their homes. They put fruit, nuts and sweets on the trees. They gave the food to the family members and friends after the holiday season. Some people say the German religious reformer Martin Luther was the first person to add lighted candles to the tree. They say he did this to show how wonderful the stars had appeared as he travelled one night.
In the early 1800’s, German settlers in the state of Pennsylvania were the first to celebrate the holiday with Christmas trees in the United States. The Christmas tree tradition spread to many parts of the world. Today, some form of the Christmas tree is part of most Christmas celebrations.

Bob Wallace was 25 minutes from home in Tennessee, on a cold December night in 2015 when he got a cell phone call from his mother. “The mountain is on fire,” she screamed, “and Brian’s up there!”
Wallace’s family owned a dozen rental cabins (小屋) on Shields Mountain, and Wallace’s friend and fellow rental-cabin owner, Brian McGee, aged 56, was up there trying to put the fire out by himself. Wallace, 32, lived on the mountain too.
Wallace turned around and headed for a dirt road. He made it about halfway up the steep, winding path before his front-wheel-drive car gave up. He called McGee, who drove down in his pickup so they could fight the fire together.
They headed first to their rental cabins. “I wanted to make sure our guests were gone. They were,” says Wallace. At that point, he had a choice: try to save his cabins or rescue people renting other cabins nearby. “On the moun¬tain, you don’t have many locals. They’re mostly tourists who don’t know their way around,” he says.
Over the next two hours, the two friends drove through the smoky moun¬tain, knocking on doors and leading panicked people to safety. “I know that mountain so well,” Wallace says, “I could drive and know exactly where I am just by time traveled.” Thanks to their brave and immediate action, the two helped 14 people out of the danger.
Fourteen people died that night in Sevier County. But the fire didn’t take away a single life on Shields Mountain. And though his home and business were destroyed, Wallace remains calm. “I wasn’t worried about my loss, not when I saw those families trapped on the mountain,” he says, “I knew I was gonna help them.”
