  Shenzhen ,Jan 1.2018——Shenzhen has become the world's first city to make all its public buses,about 16359,run on electricity.A total of 12518 taxis,or 62.5 percent of all the taxis in the city are electric ones."We will replace the rest of the taxis with electric ones by 2020."said Mr Chen from the government.
  "I have been a driver for twenty years,"said Mr Zhang,a driver who started to drive e-buses a month ago.We had several rounds of training and passed strict exams before we were allowed to drive the e-buses.
  The city has built 8000 charging pole and 501 bus charging stations."A bus can be fully charged within two hours and the charging poles can serve 300 buses a day at our station.Since the replacement,the bus terminal has become quiet,even as the e-buses are entering and exiting the station."said Mr Guan,the manager of Qinghu Bus Station.
  The use of e-buses and e-taxis plays an important role in improving air quality.In a year,the e-buses use 72.9 percent less energy than the traditional ones.The e-taxis will save the energy of 119000 tons of standard coal.
  Shenzhen was one of the first 13 cities to take part in the National New-energy Vehicle Program.In 2017,the city spent 3.3 billion yuan on e-buses and the charging equipment.The city also encourages people to buy new-energy cars or e-cars by reducing their payment.

  Artificial Intelligence,or AI in short,is the science of giving computers and machines ability to think and work like humans.AI scientists and engineers have made a lot of cool technologies.
  AI is rapidly catching up with the human ability to read faces.As a result,facial recognition is used a lot in the world.Chinese police use this technology to identify criminals.Once they caught a criminal when he attended a concert.It also checks the ID of ride-hailing drivers and lets people pay for things with a smile.
   AI is also used in self-driving cars,which are believed to be the future of driving.Most drivers may wave or nod at passers-by to let them cross the street,but self-driving cars don't have this ability.Carmakers are testing a light signal system to help them speak to humans.The system can show what self-driving cars will do.For example,if a driverless car is yielding,it will flash two white lights side to side.A rapidly flashing light tells passers-by that the car is about to speed up.
   Service Robots also show you how powerful AI is.Imagine this—you come back home from school and your robot housekeeper is waiting for you at the door.After dinner he teaches you to play the piano,just like a real music teacher.Such thoughts will soon happen in the real world.In the future,more and more service robots will become good home helpers.
  AI is so powerful that it can help human beings and even replace us in many jobs.
