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 was granted（授予）a license to test its self-driving cars on open roads in Beijing, China Daily reported．

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 revolutionize（彻底改变）the way we get around． They are safer and more environmentally friendly than regular 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 put a little water in front of the car＇s sensors（传感器）while it was moving． The car thought that the water was dangerous and slowed down or changed direction． Flaws like this could be used by people to trick self-driving cars．

The software that is used to direct the cars may not be safe enough, reported LiveScience． It may crash（崩溃)． When we use our computers or smartphones, they sometimes crash without any reason． But if this happened to a self-driving car, the results could be terrible． Improvements to the software could be a solution to this problem．

26． was the first to develop self-driving cars． A．Google B．Tesla C．Uber D．Baidu

27．What＇s the meaning of the underlined word “remove” in Chinese? A．增加 B．消除 C．产生 D．躲避

B．the car＇s sensor C．the car＇s driver D．the researcher

29．When sensing something unusual on the road, self-driving cars will ．

A．run faster than before B．slow down or change direction C．run along the road side D．stop and move around it

A．Self-driving cars will be used as taxis in Beijing．

B．Traveling in self-driving cars can prevent traffic accidents．

C．The software about self-driving cars should be improved to solve the safety problem．
