Text3 In the past several years,as the nascent medium of virtual reality has come into its own,scientists and creators have begun to explore its potential effects on the human mind.Some are undoubtedly positive-as,for instance,when the technology is used to help war veterans overcome posttraumatic stress disorder,or as a means to expand a person's capacity for compassion.But the immediacy of virtual reality has a dark side,too.Several months ago,Michael Madary and Thomas K.Metzinger,researchers from the Johannes Gutenberg University of Mainz,in Germany,published a series of recommendations on the ethical design and implementation of virtual reality.Their appraisal of the medium's psychological force is both studious and foreboding."The power of virtual reality to induce particular kinds of emotions could be used deliberately to cause suffering,"they write."Conceivably,the suffering could be so extreme as to be considered torture."In filmmaking,the director must perform a kind of seduction of dread,leading viewers through an escalating series of psychological states.In the immersive world of virtual reality,no such dance is required.Part of the power of virtual reality-based horror comes from the fact that the director knows exactly where the viewer is looking."With that knowledge,we can play mind tricks or trigger events based on the gaze,"Jon Hibbins,the director of Psytec Games,a London-based virtual reality studio,said.For instance,he said,in Psytec's most recent fantasy-horror title,Crystal RiR,"a monster can appear in a vent only when the player looks at the vent."Hibbins claims that,as viewers'brains are tricked into believing that they are physically present in a reality,the memories they form are much stronger than those made when watching so-called flat-screen media.To soften these memories,Hibbins and his team have introduced a slider into their game that allows players to control the intensity of the horror."'Normal'will be an average scare experience,"he said."You'Il hear voices in the distance,ghosts in the corridors,sound from the voids,and snakes in the corridors.'Extreme'introduces jump scares,such as ghost figures that run through your body.It really does offer everyone an option."Stephan said,"Long-term,perhaps it's a case of building literacy in players and viewers so they understand when the scares are coming.For now,I think that means taking it slow."35.Which of the following would be the best title ofthe text?

Passage 2
Reality television is a genre of television programming which, it is claimed, presents unscripted dramatic or humorous situations, documents actual events, and features ordinary people rather than professional actors. It could be described as a form of artificial or "heightened"documentary. Although the genre has existed in some form or another since the early years of television, the current explosion of popularity dates from around 2000.
Reality television covers a wide range of television programming formats, from game or quiz shows which resemble the frantic, often demeaning programmes produced in Japan in the 1980s and 1990s (a modern example is Gaki No Tsukai), to surveillance-or voyeurism-focused productions such as Big Brother.
Critics say that the term "reality television" is somewhat of a misnomer and that such shows frequently portray a modified and highly influenced form of reality, with participants put in exotic locations or abnormal situations, sometimes coached to act in certain ways by off-screen handlers,and with events on screen manipulated through editing and other post-production techniques.
Part of reality television's appeal is due to its ability to place ordinary people in extraordinary situations. For example, on the ABC show, The Bachelor, an eligible male dates a dozen women simultaneously, travelling on extraordinary" dates to scenic locales. Reality television also has the potential to turn its participants into national celebrities, outwardly in talent and performance programs such as Pop Idol, though frequently Survivor and Big Brother participants also reach some degree of celebrity.
Some commentators have said that the name "reality television" is an inaccurate description for several styles of program included in the genre. In competition-based programs such as Big Brother and Survivor, and other special-living-environment shows like The Real World, the producers design the format of the show and control the day-to-day activities and the environment,creating a completely fabricated world in which the competition plays out. Producers specifically select the participants, and use carefully designed scenarios, challenges, events, and settings to encourage particular behaviours and conflicts. Mark Burnett, creator of Survivor and other reality shows, has agreed with this assessment, and avoids the word "reality" to describe his shows; he has said, "I tell good stories. It really is not reality TV. It really is unscripted drama."
Pop Idol__________.

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.

To Survive or to Vanish1.Over 3.6 billion years ago,the first creature was born in the world.Since then,the earth started its era with life.The history of life on earth has been a history of interaction between living things and their surroundings.To a large extent,the physical form and the habits of the earth's vegetation and its animal life have been molded by the environment. Considering the whole span of earthly time,the opposite effect,in which life actually modifies its surroundings,has been relatively slight. Only in the present century has one species一man acquired significant power to alter the nature of his world.2.During the past 25 years,this power has not only become increasingly great but it has changed in character. The most alarming of all man's assaults upon the environment is the contamination of air,earth,rivers,and sea with dangerous and even lethal materials. This pollution is for the most part irrecoverable.In this now universal contamination of the environment,chemicals are the sinister partners of radiation in changing the very nature of the world the very nature of its life. Chemicals sprayed on croplands or forests or gardens lie long in soil,entering into living organisms, passing from one to another in a chain of poisoning and death.Or they pass mysteriously by underground streams until they emerge and combine into new forms that kill vegetation,sicken cattle,and work unknown harm on those who drink from once pure wells."Man can hardly even recognize the devils of his own creation,"as a scientist has said.3.Hundreds of millions of years have passed before the globe produced the life that now inhabits the earth.Given time not in years but in millennia life adjusts,and a balance has been reached.But in the modern world there is no time.4.The quick steps of change follows the impetuous pace of man rather than the deliberate pace of nature.Radiation is now the unnatural creation of man's tampering with the atom.The chemicals are the synthetic creations of man's inventive mind,having no counterparts in nature.5.To survive these chemicals would require not merely the years of one man's life but the life of generations.And even this,were it by some miracle possible,would be futile,for the new chemicals come from our laboratories in an endless stream;almost five hundred annually find their way into actual use in the United States alone.Among them are many that are used in man's war against nature.Since the mid l940's over 200 basic chemicals have been created for use in killing insects,weeds,and other organisms described as"pests".6.It is not my contention that chemical insecticides must never he used.I do contend that we have put poisonous and biologically potent chemicals indiscriminately into the hands of persons largely or wholly ignorant of their potentials for harm. We have subjected enormous numbers of people to contact with these poisons,without their consent and often without their knowledge.I contend,furthermore,that we have allowed these chemicals to be used with little or no advance investigation of their effect on soil,water,wildlife,and man himself. Future generations are unlikely to forgive our lack of concern for the integrity of the natural world that supports all life.Paragraph 1_______A:Man should be cautious in chemical use.B:It takes generations for mankind to adapt themselves to the chemicals.C:Chemicals are human's inventionD:Human's power increases and has changed its character in the past quarter century.E:The new change in the relationship between earth and its creature一human's power playing a greater role in changing the worldF: Modern world gives no time for nature to adjust to human.

第二篇Where Have All the Frogs Gone?In the 1980s,scientists around the world began to notice something strange:Frogs were disappearing. More recent research has shown that many kinds of amphibians（两栖动物）are declining or have become extinct. They have been around for a long time一over 350 million years.Why are they dying out now?Scientists are seriously concerned about this question.First of all,amphibians are an important source of scientific and medical knowledge.By studying amphibians,scientists have learned about new substances that could be very useful for treating human diseases. Further research could lead to many more discoveries,but that will be impossible if the amphibians disappear.The most serious aspect of amphibian loss,however,goes beyond the amphibians themselves.Scientists are beginning to think about what amphibian decline means for the planet as a whole.If the earth is becoming unlivable for amphibians,is it also becoming unlivable for other kinds of animals and human beings as well?Scientists now believe that amphibian decline is due to several environmental factors. One of these factors is the destruction of habitat,the natural area where an animal lives. Amphibians are very sensitive to changes in their habitat.If they cannot find the right conditions,they will not lay their eggs一These days,as wild areas are covered with houses,roads,farms,or factories,many kinds of amphibians are no longer laying eggs. For example,the arroyo toad（蟾蜍）of southern California will only lay its eggs on the sandy bottom of a slow-moving stream.There are very few streams left in southern California,and those streams are often muddy because of building projects. Not surprisingily,the arrovo toad is now in danaer of extinction.There are a number of other factors in amphibian decline.Pollution is one of them.In many industrial areas,air pollution has poisoned the rain,which then falls on ponds and kills the frogs and toads that live there,In farming areas,the heavy use of chemicals oncrops has also killed off arrtphibians.Another factor is that air pollution has led to increasedlevels of ultraviolet (UV) light. This endangers amphibians, which seem to be especiallysensitive to UV light. And finally, scientists have discovered a new disease that seems tobe killing many species of arnpttibians in different parts of the world.All these reasons for the disappearance of amphibians are also good reasons for moregeneral concern. The destrriction of land, the pollcition of the air and the water, thechanges in our atmosphere, the spread of diseases-these factors affect human beings,too. Amphibians are especially sensitive to environmental change. Perhaps they are likethe canary （金丝雀）bird that coal miners once used to take down into the mines to detectpoisonous gases. When the canary became ill or died,the miners knew that dangerous gases were near and their own lives were in danger.The arroyo toad is disappearing becauseA:it has been threatened by frogs. B:it is losing its habitat.C:a disease has been killing its eggs. D:it can't bear the cold of winter.

A Star Is Born1 The VLT (Very Large Telescope) is the world's largest telescope（望远镜）and is taking astronomers（天文学家） further back to the Big Bang than they ever thoughtpossible.Located 2,600 metres up in the Chilean Andes,it has four huge mirrors,each about the size of a London bus.The VLT is so powerful it can spot a burning match 10,000 kilometres away.2 This astonishing power will allow astronomers to see events in space from the birth of stars to the collision（碰撞）of galaxies（星系）on the edge of the cosmos（宇宙）.The VLT is giving astronomers their best-ever view of the cosmos.The power of the VLT to see the smallest detail at the furthest distances makes its designers amazed.3 Take the case of Eta Carinae,one of the most explosive stars in the universe.This star produces ultraviolet laser rays（紫外线）and it will destroy itself in a few million years' time. It is five times brighter than the sun and when it explodes it is going to be a sight worth waiting for!4 But it is at distances of millions,even billions,of light years that the VLT really shows its power. The VLT can detect light that set out on its journey before the earth even existed. This gives astronomers their first-ever detailed views of events that took place in the earliest days of the cosmos.5 In other words,the VLT is a kind of a time machine.It takes astronomers back to a time when complete galaxies crashed into each other. The effects of these past collisionscan now be seen by scientists,and astronomers believe the telescope will reveal more about these exciting' events in the years to come.One day,we might be able to say we have traveled back to the beginning of time,and we will have a much clearer picture of how our planet was born.Scientists believe the VLT will tell us more about_________.A:its detecting powerB:millions of light years away in spaceC:the location of the VLTD:as an exampleE:the birth of the earthF:the rotation of the earth

问答题The Importance of being Interested 1) Now I have recalled these beginnings of the careers of Franklin, Darwin and Mozart because they strikingly illustrate a profound psychological truth the significance of which can scarcely be overestimated. 2) It is fl truth, to be sure, that has long been partially recognized. 3)But its full meaning has not been--and could not be—appreciated until quite recently. 4)Only within the past few years has scientific research effected various discoveries which make its complete recognition possible and of supreme importance—of such importance that practical application of the principles involved would make for an immediate and stupendous increase in human happiness, efficiency, and welfare. 5)Stated briefly, the truth in question is that success in life, meaning thereby t he accomplishment of results of real value to the individual and to society, depends chiefly on sustained endeavor springing out of a deep and ardent interest in the tasks of one's chosen occupation.
