3．What will the car be like in the future？Maybe we can sit in a car that can drive itself．
About 40years ago，scientists from the United States started to develop self-driving cars （无人驾驶汽车）．The most famous recent one was made by Google in 2009．There are cameras and radars （雷达） on the top of the car．They allow the computer in the car to draw a 3D map of the environment．Chinese scientists have also successfully developed a self-driving car．The car made a trip from Changsha to Wuhan．
Is a self-driving car safe？A recent study shows that robots make safer drivers than humans．If only 10% of cars on the street are self-driving，they will save 1，000lives every year．If 90% of vehicles （交通工具） are self-driving，21，700lives will be saved a year．However，a self-driving car is expensive and each costs about 100，000．So it is impossible to be very popular in the near future．

Animals are important in Indian culture and some are treated in a special way．For example，a lot of elephants aren't（71）wild．They are domesticated（驯养）．They aren't kept as pets，but as working animals．Every working elephant （72）has its own keeper．An elephant and its keeper meet for the first time when they are both young，and they grow up together．In fact，their relationship continues for the rest of the elephant's （73）life-perhaps 40years．Lots of elephants work in the forest，moving heavy （74）trees when they are cut down．Some give rides to tourists，or （75）carry people during celebrations and festivals．Keepers take excellent care of their elephants，feeding them （76）well and giving them a bath at the end of the working day．
（77）Another special animal in India is the cow．Cows are protected animals，（78）so they aren't kept on farms or killed for food，although people do use their milk．So in India you can often see cows walking around towns and cities，and nobody tries （79）to control them．If they sit down in the middle of the road，people （80）usually drive around them!Do you think it's interesting？
