robots is just silly.The real problem relates to the possibility that artificial intelligence(AI) may become extremely good at achieving something other than what we really want.In 1960 a well-known mathematician Norbert Wiener,who founded the field of cybernetics(控制论),put it this way:“If we use,to achieve our purposes,a mechanical agency with whose operation we cannot effectively interfere(干预),we had better be quite sure that the purpose put into the machine is the purpose which we really desire.”A machine with a specific purpose has another quality,one that we usually associate with living things:a wish to preserve its own existence.For the machine,this quality is not in-born,nor is it something introduced by humans;it is a logical consequence of the simple fact that the machine cannot achieve its original purpose if it is dead.So if we send out a robot with the single instruction of fetching coffee,it will have a strong desire to secure success by disabling its own off switch or even killing anyone who might interfere with its task.If we are not careful,then,we could face a kind of global chess match against very determined,super intelligent machines whose objectives conflict with our own,with the real world as the chessboard.The possibility of entering into and losing such a match should concentrate the minds of computer scientists.Some researchers argue that we can seal the machines inside a kind of firewall,using them to answer difficult questions but never allowing them to affect the real world.Unfortunately,that plan seems unlikely to work:we have yet to invent a firewall that is secure against ordinary humans,let alone super intelligent machines.Solving the safety problem well enough to move forward in AI seems to be possible but not easy.There are probably decades in which to plan for the arrival of super intelligent machines.But the problem should not be dismissed out of hand,as it has been by some AI researchers.Some argue that humans and machines can coexist as long as they work in teamsyet that is not possible unless machines share the goals of humans.Others say we can just “switch them off” as if super intelligent machines are too stupid to think of that possibility.Still others think that super intelligent AI will never happen.On September 11,1933,famous physicist Ernest Rutherford stated,with confidence,“Anyone who expects a source of power in the transformation of these atoms is talking moonshine.” However,on September 12,1933,physicist Leo Szilard invented the neutron-induced(中子诱导) nuclear chain reaction.1.Paragraph 1 mainly tells us that artificial intelligence may .A.run out of human controlB.satisfy humans real desiresC.command armies of killer robotsD.work faster than a mathematician2.Machines with specific purposes are associated with living things partly because they might be able to .A.prevent themselves from being destroyedB achieve their original goals independentlyC.do anything successfully with given ordersD.beat humans in international chess matches3.According to some researchers,we can use firewalls to .A.help super intelligent machines work betterB.be secure against evil human beingsC.keep machines from being harmedD.avoid robots affecting the world4.What does the author think of the safety problem of super intelligent machines?A.It will disappear with the development of AI.B.It will get worse with human interference.C.It will be solved but with difficulty.D.It will stay for a decade.B(2017天津重点中学4月八校联考)The weather affects many aspects of peoples daily life.Knowing and understanding what the weather is doing is useful.However,the weather is also one of the most unpredictable elements in the world.Although many people watch the morning news and gather the information about the weather,this is often wrong.Whole days can be ruined by believing that the weather will be one thing,when it turns out to be another.However,owning wireless weather stations allows the owners to monitor the weather for themselves.Not only will these weather stations allow the owners to see what the weather is doing,but it is personalized to them and their area.Wireless weather stations are specifically prepared for the immediate neighborhood.Plans will be able to be made,and important decisions will no longer be ruined by bad weather.Although these weather stations are typically seen in homes,they can also be used very easily on farms and fishing boats.Both farmers and fishermen rely on the weather for their business and using up-to-date weather information is quite indispensable.By using the wireless weather stations,it can determine for them when to harvest crops and head back to the shore.Due to the size of the weather stations,they can be moved very easily and used wherever is necessary for people.The wireless weather stations are great for all homes,especially for areas that suffer from extreme weather conditions.The up-to-date,instant weather reports will allow a person to monitor what the weather is doing and if the bad weather is heading in their direction.Extreme weather tends to come very quickly;therefore,any information that is received is helpful.The weather stations are very simple to set up and are run by solar panels (太阳能电池板),ensuring they will work even if there is a power cut.They are far smaller than those in previous years and give a couple of very simple read-outs for the owner.They are easy to use and fascinating to understand.5.From Paragraph 2,the author intends to .A.show us how unpredictable the weather used to beB.explain the value of having wireless weather stationsC.make it clear how popular the morning news isD.show how people got weather information in the past6.What does the underlined word “indispensable” in Paragraph 4 mean?A.Essential.B.Indifferent.C.Attractive.D.Impossible.7.What can we learn about a wireless weather station?A.The information it provides is slow but more specific.B.It is hard to set up but can be moved from one place to another.C.It is economical and saves money in the long run.D.It can continue to work even if there is a power failure.8.Whats the main idea of the text?A.The weather and its effects on peoples daily life.B.The weatherthe most unpredictable element in the world.C.Good reasons for having wireless weather stations.D.The importance of knowing and understanding the weather.导学号07020014.七选五(2017安徽四校联考)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。Avoid
