Directions: there are 2 passages in this section. each passage is followed by some questions or unfinished statements for each of them there are four choices marked a, b, c)and D) You should decide on the best choice and mark the corresponding letter on Answer sheet 2 with a single line through the centre.
Questions 46 to 50 are based on the following passage.
In the beginning of the movie, robot, a robot has to decide whom to save after two cars plunge into the water-del spooner or a child. even though spooner screams"save her save her! "the robot rescues him because it calculates that he has a 45 percent chance of survival compared to sarah's 11 percent. the robot's decision and its calculated approach raise an important question:
would humans make the same choice? and which choice would we want our robotic counterparts to make?
Isaac asimov evaded the whole notion of morality in devising his three laws of robotics, which hold that 1. robots cannot harm humans or allow humans to come to harm; 2. robots must obey humans, except where the order would conflict with law i; and 3. robots must act in self-preservation, unless doing so conflicts with laws i or 2. these laws are programmed into asimov's robots-they don' t have to think, judge, or value. they don't have to like humans or believe that wrong or bad. they simply don't do it.
The robot who rescues spooner s life in / robot follows asimov's zeroth law: robots cannot harm humanity(as opposed to individual humansor allow humanity to come to harm--an expansion of the first law that allows robots to determine what's in the greater good. under the first law,a robot could not harm a dangerous gunman, but under the zeroth law, a robot could kill the gunman to save others.
Whether it's possible to program a robot with safeguards such as asimov's laws is debatable a word such as"harm"is vague (what about emotional harm is replacing a human employ harm), and abstract concepts present coding problems. the robots in asimov's fiction expose complications and loopholes in the three laws, and even when the laws work, robots still have to assess situation.
Assessing situations can be complicated. a robot has to identify the players, conditions, and possibe outcomes for various scenarios,Its doubtful that a computer program can do that-aleast, not without some undesirable results. a roboticist at the bristol robotics laboratory programmed a robot to save hur
oxies(5) called""from danger. when one h-boheaded for danger, the robot successfully pushed it out of the way. but when two h-bots became percent of the time, unable to decide which to save and letting them both"die. "the experiment highlights the importance of morality without it, how can a robot
decide whom to save or what's best for humanity, especially if it can't calculate survival odds?
46. what question does the example in the movie raise?
a) whether robots can reach better decisions
b) whether robots follow asimov's zero"
d) how robots should be programmed.
47. what does the author think of asimovs three laws of robotics?
a) they are apparently divorced from reality.
b)they did not follow the coding system of robotics.
c)they laid a solid foundation for robotics.
d) they did not take moral issues into consideration.
48. what does the author say about asimov's robots?
a they know what is good or bad for human beings
b)they are programmed not to hurt human begings
c)they perform duties in their owners'best interest.
d)they stop working when a moral issue is involved.
49. what does the author want to say by mentioning the word"harm"in asimov's laws?
a)abstract concepts are hard to program.
b) it is hard for robots to make decisions
c) robots may do harm in certain situations
d) asimov's laws use too many vague terms
50. what has the roboticist at the bristol robotics laboratory found in his experiment.
a)robots can be made as intelligent as human begings some day
b) robots can have moral issues encoded into their program
c)robots can have trouble making decisions in complex scenarion.
d)robots can be programmed to perceive potential perils.
Questions 5i to 55 are based on the following passage.
Our world now moves so fast that we seldom stop to see just how fast we seldom stop to see just how far wu have come in just a few year.The latest iPone 6s,for example,has a dual-core proccssor and fite nicely into your pocket. by comparison, you would expect to find a technological specification like this on your tandard laptop in an office anywhere in the world.
its no wonder shat new applications for the internet of things are moving ahcad fast when almost every new decice we buy has a plup on the eng of it or a wireless connection to the internet. Soon, our current smartphone lifestyle wil
ate our own smart home lifestyle too.
All researches agree that close to 25 billion devices,things and sensors will be connected by 2020 which incidentally is also the moment that millennials(千禧一代) are expected to make up of our overall workforce, and the fully connected home . become a reality for large umbers of people worldwide.
However this is just the tip of the proverbial iceberg as smart buildings and even cities increasingly become the norm as leaders and business owners begin to wake up to the massive savings that technology can deliver through connected sensors and new forms of automation coupled with ligent energy and facilities managemen.
Online security cameras, intelligent lighting and a wealth of sensors that control both temperature and air quality are offering an unprecedented level of control, efficiency, and improvements to hat were once classed necessary costs when running a business or managing a large building.
We can expect that the ever-growing list of devices, systems and environments remain connected,always online and talking to each other. the big benefit will not only be in the housing of this enormous and rapidly growing amount of data, but will also be in the ability to run real time data analytics to extract actionable and ongoing knowledge.
The biggest and most exciting challenge of this technology is how to creatively leverage this ever-growing amount of data to deliver cost savings, improvements and tangible benefits to both businesses and citizens of these smart cities
The good news is that most of this technology is already invented. let's face it, it wasn't too long ago that the idea of working from anywhere and at anytime was some form of a distant utopim(乌托邦式的) dream, and yet now we can perform almost any office-based task from any location in the world as long as we have access to the internet.
it's time to wake up to the fact that making smart buildings, cities and homes will dramatically improve our quality of life in the years ahead.
