7.Ladies and gentlemen,say hello to PIBOT.Developed in South Korea,this little machine is about the size of a child's toy,and has a head that kind of looks like a toaster (烤箱).It's also able to fly a plane.
      The researchers responsible for the robot's development have actually managed to program it with all the knowledge and skills necessary to operate a standard airplane.Through a built-in webcam (网络摄像机),PIBOT is able to gather information about its surroundings-such as location,airspeed,and weather conditions.
       With all of this information,it's able to make decisions in much the same way as a human pilot would.It's already completed one successful test flight-sort of.In the video presented at IROS 2014 in Chicago,PIBOT was seen guiding the airplane through a short test flight in a flight simulator (模拟器)-a process which included both takeoff and landing.
       It's super cool.
      Now,it's worth mentioning that-even as impressive as PIBOT is-we aren't going to be seeing it in any real airplanes at any point in the near future.Although the little robot is certainly able to operate a plane,it doesn't quite have the skills necessary to address some of the real world situations met by pilots-such as bad weather or mix-ups on the runway.It doesn't meet the government's rules,either.
      The inventors aren't terribly discouraged,however.They expect that it's only a matter of time before they manage to get PIBOT up to the necessary standards.When the day comes,we might see airlines put to work a whole new type of pilot; one who never tires,never gets hungry,and never makes mistakes.
      So…if you've a career in aviation (航空),it might soon be time to start planning for retirement (退休).
28.We know from the text that PIBOTA.
A.is designed to operate a plane      
B.can serve as a toaster
C.was developed in Chicago            
D.is very large  
29.In the presented video,PIBOTD.
A.competed with a human pilot
B.completed several test flights
C.made decisions totally like humans
D.successfully guided a plane to take off and land
30.Why won't PIBOT be put into use?C
A.It can't predict weather conditions.
B.It doesn't have the skills to operate a plane.
C.It can't deal with real world situations.
D.It can't gather information abo ut its surroundings.
31.It can be learned from the text thatB.
A.PIBOT won't make any mistake in a flight
B.the inventors are confident about the future of PIBO.
C.the researchers will have to abandon the plan
D.PIBOT will surely replace human pilots one day.
