Don’t be too surprised if you see a car going...

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. Last month, Baidu tested its self-driving cars on open roads in Beijing. Self-driving cars have been in progress since 2010, when Google said it was making such cars. From then on, companies like Tesla, Uber and Baidu tried to make and test their own self-driving cars.

Now, many people really want to buy a self-driving car if they have enough money. They think it will make their life easier. However, every coin has two sides.

Normally, when there is an obstacle (障碍物) in front of the self-diving car, the car will stop. But sometimes it also makes mistakes. In one test, when researchers sent a point of light in front of a moving self-driving car, the car stopped. And in another test, when researchers did it again, the car moved to another road. If scientists don’t solve the problem, some people may use the mistake to do bad things.

So self-driving at least now is still not safe enough. When we use our computers or smartphones, they sometimes don’t work well without any reason. If this happens to a self-driving car the results might be dangerous. So scientists are making improvements to work out the problem.

If you go to London, you will see a lot of buses and cars on the road.You will also see lots of bikes because more and more people travel by bike.There are a lot of reasons for this.First, it's not expensive to buy a bike and it is quick, too.You often have to wait for a bus for half an hour.After you get on the bus, there are so many other buses and cars on the road that the bus moves very slowly.The underground train is quick but often crowded.

I traveled to work by bus for about four years.I often arrived at work late and tired.Then one day, about two years ago, a friend of mine said, “I go to work by bike every day.Please come and join me.” “But my bike is old, and there are so many buses and cars on the road.I'll feel frightened，” I answered.“You needn't feel afraid.If you follow me and we ride slowly, you will be fine，” he said.

The next day I bought a new bike.Although we went slowly, we arrived at work soon.It took 40 minutes to go by bus, but only half an hour by bike.

Now I love riding a bike to work.I arrive at work quickly and I've saved a little money, and more importantly, I feel healthy.Many people think my idea is good and maybe you will see more bikes on the road in the future.

If you go into the forest with friends, stay with them. If you don’t, you may get lost. Sit down and stay where you are. Don’t try to find your friends, but let them find you instead（相反）.
