共用题干Do You Have a Sense of Humor?Humor and laughter are good for us.There is increasing evidence that they can heal us physically, mentally,emotionally,and spiritually.In fact,every system of the body responds to laughter in some positive,healing way.So how can we get more laughter into our lives?______(46)Psychologist and author.Steve Wilson,has some answers.Many people believe that we are born with a sense of humor.They think,"either you've got it,or you don't."Dr.Wilson points out that this is false.______(47)The parts of the brain and central nervous system that control laughing and smiling are mature at brith.______(48)(After all,when a baby laughs,we don't rush over and say,"That kid has a great sense of humor!")A sense of humor is something that you can develop over a lifetime.Sometimes people think that they don"have a good sense of humor because they are not good joke tellers.Dr.Wilson reminds us that telling jokes is only one of many ways to express humor.______(49) Then we will make others laugh, too.A person who has a true sense"'humor is willing and able to see the funny side of everyday life.One of the best definitions of a sense of humor is "the ability to see the nonserious element in a situation." Consider this sign from a store window." Any faulty merchandise will be cheerfully replaced with merchandise of equal quality." The store manager probably placed the sign in the window to impress customers with the store's excellent service.______(50)As Dr.Wilson says,"a good sense of humor means that you don't have to be funny;you just have to see what's funny."______(50)A:What is true,however,is that we are born with the capacity to laugh and smile.B:However,that does not mean that infants have a sense of humor.C:He advises us to lose our inhibitions（抑制）and try to laugh at ourselves.D:Is it possible to develop a sense of humor?E:Everyone experiences this emotion.F:He had a serious purpose,but if you have a sense of humor,you will probably find the sign funny!

共用题干第二篇The next big breakthrough in artificial intelligence could come from giving machines not just more logical capacity,but emotional capacity as well.Feeling aren't usually associated with inanimate（无生命的）machines, but Posalind Picard, a professor of computer technology at MIT,believes emotion may be just the thing computes need to work effectively.Computers need artificial emotion both to understand their human users better and to achieve self-analysis and self-improvement,says Picard."If we want computers to be genuinely intelligent,to adapt to us,and to interact naturally with us,then they will need the ability to recognize and express emotions,to have emotions,and to have what has come to be called emotional intelligence,"Picard says.One way that emotions can help computers,she suggests,is by helping keep them from crashing. Today's computers produce error messages,but they do not have a "gut feeling" of knowing when something is wrong or doesn't make sense.A healthy fear of death could motivate a computer to stop trouble as soon as it starts.On the other hand, self-preservation would need to be subordinate to service to humans.It was fear of its own death that promoted RAL,the fictional computer in the film 2002 :A Space Odyssey, to extermine（消灭）most of its human associates.Similarly,computers that could"read"their users would accumulate a store of highly personal information about us一not just what we said and did,but what we likely thought and felt."Emotion not only contribute to a richer quality of interaction,but they directly impact a person's ability to interact in an intelligent way,"Picard says."Emotional skills,especially the ability to recognize and express emotions,are essential for natural communication with humans." What does the author think about the computers with emotions?A:The author has high expectation for its potential in the future.B:The author worries that it will threaten the security of human beings.C:The author doubts its capacity to interact with human beings.D:The author believes that it will take the place of human beings in many aspects.
共用题干第一篇Almost Human?Scientists are racing to build the world's first thinking robot.This is not science fiction: some say they will have made it by the year 2020.Carol Packer reports.Machines that walk,speak and feel are no longer science fiction.Kismet is the name of an android（机器人）which scientists have built at the Massachusetts Institute of Technology(MIT).Kismet is different from the traditional robot because it can show human emotions.Its eyes,ears and lips move to show when it feels happy,sad or bored. Kismet is one of the first of a new generation of androids一robots that look like human beings一which can imitate human feelings.Cog,another android invented by the MIT, imitates the action of a mother. However,scientists admit that so far Cog has the mental ability of a two-year-old.The optimists（乐观主义者）say that by the year 2020 we will have created humanoids （机器人）with brains similar to those of an adult human being. These robots will be designed to look like people to make them more attractive and easier to sell to the public. What kind of jobs will they do?In the future,robots like Robonaut,a humanoid invented by NASA,Will be doing dangerous jobs,like repairing space stations.They will also be doing more and more of the household work for us.In Japan,scientists are designing androids that will entertain us by dancing and playing the piano.Some people worry about what the future holds:will robots become monsters（怪物）? Will people themselves become increasingly like robots?Experts predict that more and morepeople will be wearing micro-computers,connected to the Internet,in the future.People will have micro-chips in various parts of their body,which will connect them to a wide variety of gadgets（小装置）.Perhaps we should not exaggerate（夸大）the importance of technology,but one wonders whether,in years to come,we will still be falling in love, and whether we will still feel pain.Who knows?In about 1 5 years' time from now,robotsA:will become space designers. B:will look like monsters.C:will behave like animals. D:will think like humans.
When I opened the first "Body Shop" in 1976, what I wanted to do was to earn （挣） enough money to feed my children. Today the "Body Shop" is a great company growing fast all around the world. In the years since we began, I have learned a lot. Much of what I have learned will be found in this book, because I believe that we, as a company, have something worth saying about how to run a successful business without giving up what you really believe in.It's not an ordinary business book. It is not just about my life, either. The message is that to succeed in business you have to be different. Business can be fun, and can be run with love and do good. In business, as in life, I need to enjoy myself, to have a feeling of my family and to feel excited by something unusual. I have always wanted the people who work for the "Body Shop" to feel the same way.Now this book sends these ideas out into the world, and makes them public. I'd like to think there are no limits （界限） to our "family", and no limits to what can be done. I find that an exciting thought. I hope you do, too.How does the writer feel about the business she runs?A. It's the biggest company in the world.B. It will possibly be more successful.C. It's one of the most successful businesses.D. It is the only company that is growing all around the world.

There is no creature that does not need sleep or complete rest every day.If you want to know why,just try going without sleep for a long period of time.You will discover that your mind and body would become too tired to work properly.You would become irritable and find it hard to think clearly or concentrate on your work.So sleep is quite simply the time when the ceils of?your body recover from the work of the day and build up supplies of energy for the next period of activity.One of the things we all know about sleep is that we are Unconscious in sleep,We do not know what is going on around us.But that do.esn′t mean the body stops all activity.The important organs continue to work during sleep,but most of the body functions are slowed down.For example,our breathing becomes slower and deeper.The heart beats more slowly,and the blood pressure is lower.Our arms and legs become limp(柔软的)and muscles are at rest.It would be impossible for our body to relax to such an extent if we were awake.So sleep does for us what the?most quiet rest can not do.Your body temperature becomes lower when you are asleep,which is the reason people go to sleep under some kind of covers.And even though you are unconscious,many of your reflexes(反射动作)still work.For instance,if someone tickles(使觉得痒)your foot,you will put it away in your sleep,or even brush a fly from your forehead.You do these things without knowing it.When you are sleeping,A.all of you reflexes stop workingB.most of your reflexes stop workingC.many of your reflexes still workD.all of your reflexes still work

共用题干Do You Have a Sense of Humor?Humor and laughter are good for us.There is increasing evidence that they can heal us physically mentally,emotionally,and spiritually.In fact,every system of the body responds to laughter in some positive healing way.So how can we get more laughter into our lives?_______(46)Psychologist and author Steve Wilson,has some answers.Many people believe that we are born with a sense of humor.They think,"either you've got it,or you don't."Dr.Wilson points out that this is false._________(47)The parts of the brain and central nervous system that control laughing and smiling are mature at birth.______(48)(After all,when a baby laughs,we don't rush over and say,"That kid has a great sens(of humor!")A sense of humor is something that you can develop over a lifetime.Sometimes people think that they don't have a good sense of humor because they are not good joke tellers Dr.Wilson reminds us that telling jokes is only one of many ways to express humor._______(49)Then we will make others laugh,too.A person who has a true sense of humor is willing and able to see the funny side of everyday life.On of the best definitions of a sense of humor is"the ability to see the nonserious element in a situation".Consider this sign from a store window:"Any faulty merchanJise will be cheerfully replaced with merchandise of equal quality."The store manager probably placed the sign in the window to impress customers with the store's excellent service.________(50)As Dr.Wilson says,"a good sense of humormeans that you don't have to be funny,you just have to see what's funny."_______(47)A:Everyone experiences this emotion.B:Is it possible to develop a sense of humor?C:He advises us to lose our inhibitions（抑制）and try to laugh at ourselves.D:However,that does not mean that infants have a sense of humor.E:What is true,however,is that we are born with the capacity to laugh and smile.F:He had a serious purpose,but if you have a sense of humor,you will probably find the sign funny!
共用题干Nuclear Power and Its DangerNuclear power's danger to health,safety,and even life itself can be summed up in one word:radiation.Nuclear radiation has a certain mystery about it,partly because it cannot be detected by human senses.lt can't be seen or heard,or touched,or tasted,even though it may be all around us.There are other things like that.For example,radio waves are all around us but we can't detect them,sense them,without a radio receiver.Similarly,we can't sense radioactivity without a radiation detector.But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.At very high levels,radiation can kill an animal or human being outright by killing masses of cells in vital organs.But even the lowest level of radiation can do serious damage.There is no level of radiation that is completely safe.If the radiation does not hit anything important,the damage may not be significant．This is the case when only a few cells are hit,and if they are killed outnght.Your body will replace the dead cells with healthy ones.But if the few cells are only damaged,and if they reproduce themselves,you may be in trouble.They reproduce themselves in a deformed way.They can grow into cancer.Sometimes this does not show up for many years.This is another reason for some of the mystery about nuclear radiation.Serious damage can be done without the victim being aware at the time that damage has occurred.A person can be irradiated and feel fine,then die of cancer five,ten,or twenty years later as a result.Or a child can be born weak or liable to serious illness as a result of radiation absorbed by its grandparents.Radiation can hurt us.We must know the truth.The underlined word"significant"in Paragraph 3 most probably means______.A:fatal B:meaningfulC:remarkableD:harmful

共用题干第三篇Almost Human?Scientists are racing to build the world's first thinking robot.This is not science fiction: some say they will have made it by the year 2020.Carol Packer reports.Machines that walk,speak and feel are no longer science fiction.Kismet is the nameof an android（机器人）which scientists have built at the Massachusetts Institute of Technology(MIT).Kismet is different from the traditional robot because it can show human emotions.Its eyes,ears and lips move to show when it feels happy,sad or bored. Kismet is one of the first of a new generation of androids一robots that look like human beings一which can imitate human feelings.Cog,another android invented by the MIT, imitates the action of a mother. However,scientists admit that so far Cog has the mental ability of a two-year-old.The optimists（乐观主义者）say that by the year 2020 we will have created humanoids （机器人）with brains similar to those of an adult human being. These robots will be designed to look like people to make them more attractive and easier to sell to the public. What kind of jobs will they do?In the future,robots like Robonaut,a humanoid invented by NASA,will be doing dangerous jobs,like repairing space stations.They wi}{also be doing more and more of the household work for us.In Japan,scientists are designing androids that will entertain us by dancing and playing the piano.Some people worry about what the future holds:will robots become monsters（怪物）? Will people themselves become increasingly like robots?Experts predict that more and more people will be wearing micro-computers,connected to the Internet,in the future.People will have micro-chips in various parts of their body,which will connect them to a wide variety of gadgets（小装置）.Perhaps we should not exaggerate（夸大）the importance of technology,but one wonders whether,in years to come,we will still be falling in love, and whether we will still feel pain.Who knows?In about 15 years' time from now,robotsA:will become space designers. B:will look like monsters.C:will behave like animals. D:will think like humans.

问答题TechnologyWhen faced with some new and possibly confusing technological change, most people react in one of two ways. They (1)____refuse to accept anything new, claiming that it is unnecessary or too complicated or that it somehow makes life less than human. Or they learn to (2) ada____ to the new invention, and eventually wonder how they could possibly have existed without it. (3)____computers as an example. For many of us, they still represent a (4) thr____ to our freedom, and give us a frightening sense of a future in which all (5)____(decide) will be taken by machines. This may be because they seem mysterious, and difficult to (6) und____. Ask most people what you use a home computer for, and you can usually get vague answers about how “they give you information”. In fact, even those of us who are familiar with computers, and use them in our daily work, have very little idea of how they (7)____. But it does not take long to learn how to operate a business programme, even if things occasionally go (8)____for no apparent reason. Presumably much the same happened when the telephone and the television became widespread. What seems to alarm most people is the speed of (9)____(technology) change, rather than change itself. And the objections that are made to new technology may well have a point to them, (10) si____ change is not always an improvement. As we discover during power cuts, there is a lot to be said for the oil lamp, the coal fire, and forms of entertainment, such as books or board games, that don’t have to be plugged into work.
