1、在对论点论证的过程中,每一段的首句都是该段的主题句。把握全文论点。弄清论证各段的主题句、理解文章层次,找出中心论点的位置是理解议论文的关键。体裁演练(2017北京卷)Hollywoods theory that machines with evil (邪恶的) minds will drive armies of killer robots is just silly.The real problem relates to the possibility that artificial intelligence (AI) may become extremely good at achievi
2、ng something other than what we really want.In 1960 a wellknown 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 th
3、e 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 inborn,nor is it something introduced by humans;it is
4、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 interfe
5、re 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
6、 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 ordi
7、nary 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
8、 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 t
9、hink 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 neutronind

13、y.DIt will stay for a decade.【能力提升】 AI read somewhere that we spend a full third of our lives waiting.But where are we doing all of this waiting,and what does it mean to an impatient society like ours?To understand the issue,lets take a look at three types of “waits”The very purest form of waiting i
14、s the WatchedPot Wait.It is without doubt the most annoying of all.Take filling up the kitchen sink (洗碗池) as an example.There is absolutely nothing you can do while this is going on but keep both eyes fixed on the sink until its full.During these waits,the brain slips away from the body and wanders
15、about until the water runs over the edge of the counter and onto your socks.This kind of wait makes the waiter helpless and mindless.A cousin to the WatchedPot Wait is the Forced Wait.This one requires a bit of discipline.Properly preparing packaged noodle soup requires a Forced Wait.Directions are
16、very specific.“Bring three cups of water to boil,add mix,simmer three minutes,remove from heat,let stand five minutes.”I have my doubts that anyone has actually followed the procedures strictly.After all,Forced Waiting requires patience.Perhaps the most powerful type of waiting is the LuckyBreak Wai
17、t.This type of wait is unusual in that it is for the most part voluntary.Unlike the Forced Wait,which is also voluntary,waiting for your lucky break does not necessarily mean that it will happen.Turning ones life into a waiting game requires faith and hope,and is strictly for the optimists among us.
18、On the surface it seems as ridiculous as following the directions on soup mixes,but the LuckyBreak Wait well serves those who are willing to do it.As long as one doesnt come to rely on it,wishing for a few good things to happen never hurts anybody.We certainly do spend a good deal of our time waitin
19、g.The next time youre standing at the sink waiting for it to fill while cooking noodle soup that youll have to eat until a large bag of cash falls out of the sky,dont be desperate.Youre probably just as busy as the next guy.1While doing a WatchedPot Wait,we tend to _.Akeep ourselves busy Bget absent

21、kyBreak Wait?AIt is less voluntary than the Forced Wait.BIt doesnt always bring the desired result.CIt is more fruitful than the Forced Wait.DIt doesnt give people faith and hope.4What does the author advise us to do the next time we are waiting?ATake it seriously. BDont rely on others.CDo something
22、 else. DDont lose heart.BI told my friend Graham that I often cycle two miles from my house to the town centre but unfortunately there is a big hill on the route. He replied, “You mean fortunately.” He explained that I should be glad of the extra exercise that the hill provided.My attitude to the hi
23、ll has now changed. I used to complain as I approached it but now I tell myself the following. This hill will exercise my heart and lungs. It will help me to lose weight and get fit. It will mean that I live longer. This hill is my friend. Finally I comfort myself with the thought of all those silly
24、 people who pay money to go to a gym and sit on stationery exercise bicycles when I can get the same value for free. I have a smile of satisfaction as I reach the top of the hill.Problems are there to be faced and overcome. We cannot achieve anything with an easy life. Helen Keller was the first dea
25、f and blind person to gain a university degree. Her activism and writing proved inspirational. She wrote, “Character cannot be developed in ease. Only through experiences of suffering can the soul be strengthened, vision cleared, ambition inspired and success achieved.”One of the main determinants o
26、f success in life is our attitude towards adversity (逆境). From time to time we all face hardships, problems, accidents and difficulties. Some are of our making but many are no fault of our own. While we cannot choose the adversity, we can choose our attitude towards it.Douglas Bader was 21 when in 1
27、931 he had both legs cut off following a flying accident.He was determined to fly again and went on to become one of the leading flying aviators in the Battle of Britain with 22 aerial victories over the Germans.He was an inspiration to others during the war. He said, “Dont listen to anyone who tell
28、s you that you cant do this or that. Thats nonsense. Make up your mind, youll never use crutches (拐杖) or a stick, and then have a go at everything. Go to school, and join in all the games you can. Go anywhere you want to. But never, never let them persuade you that things are too difficult or imposs
29、ible.”The biographies of great people are full of examples of how they took steps to overcome the difficulties they faced. The common thread is that they did not become depressed. They chose their attitude. They chose to be positive. They took on the challenge. They won.Nevertheless, there is still
30、the problem of how you change your attitude towards adversity.5Which of the following is true according to the author of the passage?AGoing to a gym is greatly beneficial to peoples health.BClimbing hills on bicycles is the best way to take exercise. CThose who want to achieve success cant expect to
31、 live an easy life.DPeoples attitude to adversity is the only factor of their success.6By quoting what Douglas Bader said, the author intends to tell us “_”AFailure is the mother of success.BA bad workman quarrels with his tools.CIf you risk nothing, you will have nothing.DNothing is difficult to the man who will try.7Following this passage, the author will further talk about _.Ahow his friend helped him to change
