①That future is almost here. "I think it's going to happen. In ten years. . . and hopefully much,much faster,"said Sebastian Thrun in
2021. At that time(公司) Kitty Hawk Corporation was working on developing a flying car known as eVTOL,or Electronic Vertical Take﹣Off and Landing cars.
②Flying to work or school sounds unbelievable. Not only is it fun to fly,but"it would never be crowded again,because the sky is very,"says Thrun. He also thinks eVTOLs could be greener than common cars. "We go much faster,we go in a straight line(能源). "he says.
③So far,though,flying cars haven't come into the market. Will their day come?There are still many problems to work out. Their high price means most people won't be able to buy one. So,many developers are trying to make them self﹣flying﹣no human pilot needed.
④Another problem is space. Most of them need long runways to take off and land. Flying straight up and down like a helicopter(直升机) makes it easy. But eVTOLs still need special spaces,called vertiports,especially in crowded cities. But maybe some could go on top of buildings.
⑤What do you think?Would you enjoy riding to school or visiting a friend in a self﹣flying taxi?Are flying cars a good idea,or should we find other ways to get around in the near future?
