14.Have you ever had a panic attack in mid-flight?Those that have will tell you it's not fun.And there are plenty of reasons that make people panic.Some of them focus on the state of the pilot.Are I hey tired?Stressed?Paying enough attention?Would these people feel any better if we could get rid of pilots altogether?
The technology already seems to be there-drones are not a new invention.Armies use drones in war zones,where they are controlled remotely.Even helicopters can be pi lot less,and delivers aid supplies to dangerous locations.
Aircraft accidents are rare today,but when they happen,they are getting harder and harder to solve‘That's why investigations often focus on"human factors",identifying psychological and physiological issues as a probable cause.
At the Consumer Electronics Show in Las Vegas in January.Chinese company Ehang displayed the first-ever passenger drone.To fly,the passenger needs to set up a flight plan,click"take off"and"land on a tablet,and the computer does the rest.There are other similar efforts to develop personal air transport systems in the US
and the UK.But be it a plane that's controlled remotely#or by an artificial intelligence system.whether it's just a passenger pressing a button,or a ground crew pulling the wireless strings,one fundamental question hasn't been answered yet:Would we feel at ease flying it we can't see two smartly dressed pilots inside,calmly providing us with weather updates during a storm?
It appears that people are more comfortable with a pilot directly at the controls,and on the plane.People are of the opinion that being in the vehicle while controlling it is easier than controlling it remotely.
There is also one worry:the risk of the unmanned plane getting hacked (黑客攻击).It would be necessary to have not only preventive but also recovery measure-to stop an attack from happening and"rescue"the aircraft during a hack.
Today,it might be difficult for people to accept unmanned planes because when a plane stops,it falls out of the sky.And of course,many people are already nervous about flying,while not many of us are nervous about riding in a car or on a train.
58.Which does the passage suggest is among the advantages of pi lot less planes?C
A.Passengers'safety will be ensured.
B.We'll have exactly punctual flights.
C.Pilots'conditions can be excluded.
D.They can offer a comfortable flight.
59.The present problem with pilotless planes seems to beD.
A.producing appropriate planes
B.cutting the cost of operation
C.improving current technology
D.getting passengers on board
60.It is obvious that the passage intends toA.
A.throw doubt upon unmanned planes
B.analyze the value of pi lot less planes
C.show us a wonder of new technology
D.teach us how to fly unmanned planes.
分析 本文属于说明文阅读,作者通过这篇文章主要向我们描述了无人驾驶飞机已经研发,然而许多人并不放心,文章旨在鼓励人们相信无人驾驶飞机.
解答 58.C.细节理解题.根据第三段The technology already seems to be there-drones are not a new invention.Armies use drones in war zones,where they are controlled remotely可知这段话说明无人驾驶飞机的优点是排除飞行员的干扰;故选C.
59.D.细节理解题.根据倒数第三段It appears that people are more comfortable with a pilot directly at the controls,and on the plane.People are of the opinion that being in the vehicle while controlling it is easier than controlling it remotely可知用无人驾驶飞机目前的问题是乘客的认同;故选D.
60.A.推理判断题.根据最后一段Today,it might be difficult for people to accept unmanned planes because when a plane stops,it falls out of the sky.And of course,many people are already nervous about flying,while not many of us are nervous about riding in a car or on a train可知作者对于无人驾驶飞机的态度是支持放弃对它的怀疑的;故选A
点评 考察学生的细节理解和推理判断能力,做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确的选择.在做推理判断题不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.
