Directions:For cach blank in the following passage there are four words or phrases marked A,B,C-|||-and D.Fill in each blank with the word or phrase that best fits the context.-|||-While the full picture has yet to emerge, it appears that the reason for in (log )_(2)5 of AirAsia flight-|||-QZ8501is different from the losses of MH370 and MH17earlier this year.MH17,shot down in-|||-Ukraine,was clearly a man-made disaster;QZ8SO1's disappearance ap to be weather -related-|||-MH370°sloss remains a mystery.-|||-Even though cloud d-computing(云计算)could help advance the status(状态)of the black box in-|||-terms of the in vestigation after such incidents,as we are only too aware,nature-in the form of-|||-bad weather-often plays a significant role in airline disasters.Is there anything we can do,on the-|||-ground,to lower the 51 of these weather related incidents?-|||-Recently,Microsoft Rescar illustrated that by combi real-time data from nearby flights, it i-|||-possible to 52 the wind speed to an accuracy 10 times better than the weather-|||-simulations(模拟)by supercomputers.Augment data collected from real-time sensors from-|||-the cloud,one can create a better simulation, 53 the advances in the intemet of flying things-|||-The internet of flying things refers to the technology that is ready for adoption by agencies on the-|||-ground that want to get a bird's-eye view of weather conditions.The basic technology is already-|||- 54 for less than f500:equipping a drone(无入机)or unmanned airborne vehide with a GoPro-|||-quality camera, enthusias fans can already survey the neighborhood from the air.-|||-If we look at the air crash incidents caused by bad weather conditions can the killer technology of-|||-cloud computing and augmented reality be used as a life saver?-|||-When you fly into such wind speeds, is it not difficult to change one's actions 55 ?Isn't the-|||-flight simply doomed?Not necessarily.In this case, had nearby flying objects logged(记录)the-|||-abnormal wind speeds earlier,they would have been able to inform air traffic control in time to-|||- 56 a waming to flight QZ8501.In these situations,often timely interventions(干预)can save-|||-lives.-|||-But before this idea can 57 be realized,there are at least three obstacles to overcome if we-|||-want to use the power of the internet of flying objects.-|||-The first thing to note is that these flying objects shouldn't be 58 to aircraft.We could be-|||-talking about weather balloons,drones-anything in the air,in short,but these objects need to be-|||-identifibbl.Onle.through 59 can messages from these flying objects be recognized and-|||-trusted by authorities such as FAA.So,for example,the drones that -it is imagined -will be-|||-carrying goods to households must be 60 and their call signs logged by the authorities-|||-before they can be of any practical help.At present they are not.In other words, the-|||-autonomous(非政府的)flying objects are required to collaborate with air traffic controllers if we-|||-want to build a picture that will deliver a secure and trustworthy solution-|||- 61 ,these regulated and registered flying objects need to be effectively networked,so that-|||-through the 62 of real-time data the crowd-sourced(基于大众资源的)information-|||-delivers as accurate a picture as possible.Resolving any conflicts arising from information coming-|||-in from multiple sources requires a good computational mode that can assign appropriate weight-|||-to the 63 sources.-|||-And this collected data needs to depict a physical truth to decision makers -whether they are in-|||-front of the desk in the air traffic control center,on the flight deck of a nearby aircraft or in-|||-command of the rescue team.The task of confinming available 64 .against any possible-|||-intemal flaws or extemal tampering(干扰) would require that network security levels are brought-|||-to another level-|||-These three 65 are basic,but if they can be overcome, they might offer us a better-|||-opportunity to use today's technology to provide safer air transport in the future.-|||------ddapted from a magazine article in 2014-|||-51.A.risk B.disturbance C.uncertainty D.threat-|||-52.A.check B.follow C.predict D.monitor-|||-53.A.thanks to B.in spite of C.with reference to D.other than-|||-54.A.feasible B.possible C.profitable D.available-|||-55.A.secretly B.accordingly C.ambitiously D.unexpectedly-|||-56.A.ignore B.withdraw C.issue D.reserve-|||-57.A.
