Don’t be too surprised if you see a car going down the road without a driver in Beijing these days. It might be one of Baidu’s self-driving cars.

Self-driving cars have been in development since 2010, when Google announced that it was making such cars. Since then,companies like Tesla, Uber and Baidu have been working to produce and test their own self-driving cars.

Self-driving cars are expected to change the way we get around. They are safer and more environmentally friendly than usual cars. They can remove the stress of driving and allow disabled or blind people to get around more easily.

But self-driving cars have their own flaws (缺陷)as well. In one test, researchers pointed a laser pointer (激光棒)at the car’s sensors (传感器)while it was moving. The car mistakenly thought that the laser beam(激光束)was in its way and slowed down or changed direction. Flaws like this could be used by people to trick self-driving cars.

The software (软件)that is used to direct the cars may not be safe enough. It may crash (崩溃),When we use our computers or smart phones, they sometimes crash without any reason. But if this happened to a self-driving car, the results could be deadly. Improvements to the software could be a way to deal with this problem.

Anyway, whether you like it or not, it’s only a matter of time before they’ll become more affordable and popular on our roads.

Characters:

"I"﹣Storyteller Bertie﹣storyteller's husband The White Prince﹣a lion…

We never had children of our own﹣just The White Prince﹣and I can tell you, he was enough of a family for anyone. He walked freely in the park just as we had planned he would, and ran after the deer and the rabbits whenever he felt like it; but be never did learn how to kill for himself. You can't teach old lions new tricks. He lived on deer mostly, and slept on a sofa in our living room﹣I wouldn't have him inside our bedroom, no matter(无论) how often Bertie asked. You know, I have to draw the line somewhere.

Bertie's leg was never cured. When it was bad, he often needed a stick, or me, or the lion to lean on. It pained him a lot, especially on cold and wet days, and he never slept well. On Sundays the three of us would walk around the park together, and Bertie would sit on the top of Wood Hill with his arm around the lion's neck and I would fly kites. You know, I've always loved kites. And the lion liked to break them into pieces.

The lion never showed any interest in running away, and even if he'd wanted to, the park wall was too high for an old lion to jump over. Wherever. Bertie went, he wanted to go too. And if ever Bertie went out in the car, then he'd sit by me in the kitchen, and watch me with those great amber eyes, listening all the while for the sound of Bertie's car coming up the path to the front of the house.

The lion was getting older. And he became weak in his legs and could see very little. He spent his last days sleeping at Bertie's feet. When he died, we buried(埋葬) him at the bottom of the hill. Bertie's wanted it that way so he could always see the place from the kitchen window. I suggested Bertie plant a tree in case(以防) he forgot where the lion was. "I will, but he should get more than a tree." Bertie said.

Bertie was sad for weeks, months after the lion died. There was nothing I could do to cheer him or even comfort him. He would sit for hours in his room, or go off on long walks by himself. He seemed so shut away inside himself, so distant(遥远的). Try as I did. I could not reach him.

A teenage boy couldn’t stand his parents’ family rules, so he left home. He wanted to be famous, but he had a poor education. He couldn’t find a job and had to beg for food on the street.

Years later, his mother died. Though his father was old, he was still looking for his son. He looked in every corner of the city. Wherever he went, he put up a big photo of himself on the wall. On the lower part of the photo, he wrote, “I still love you, my dearest son. Please come back home!”

One day, the son saw one of the photos on the wall. The face on the photo was familiar to him. “Is that my father?” He moved closer and read the words, “I still love you...” Tears ran down his face. He made up his mind to go back and see his dad.

It was early morning when he got home. He knocked on the door. Nobody answered, although the door did open. He rushed into his father’s bedroom. His father was sleeping. The boy woke his father up. “It’s me! Your son is back home!” The father and the son held each other with tears in their eyes. The son asked, “Why is the door unlocked? A thief could get in.” The father answered in a soft voice, “The door has never been locked since you left.”
