Though the place was not pleasant or disagreeable, my father was deeply attracted to it precisely because of its unexplored, uncultivated natural state, and the challenge.2.H rm afraid the day f s going to catch us/1 I explained, wondering what great disaster might befall us if it did.As a little girl, I believed my father's words, and was genuinely afraid of the possible disaster—if we didn't hurry up, the day would catch us and terrible things might happen.3....from time to time he was halfheartedly sought for trial, though few crimes seemed to lead directly to his door.In this place, though the police wound make some effort without real earnest to investigate Watson and bring him to court, there seemed to be little concrete evidence to prove that he was responsible for certain illegal activities.4.The stranglehold Watson had over this section of Florida was not dissimilar to the unscrupulous activities of certain lawmen, other legal crooks, and even governors that our state was to suffer through its history.The control Watson had over this part of Florida was much similar to the dishonest or illegal activities of the law-enforcing officials and governors which Florida witnessed in the 20th century.5.There was the little shack, not the most gracious of living quarters, and there was a murderer for our nearest and only neighbor, about thirty miles away.Before the family built their own house, they lived in a shabby cabin at Gopher Key, close to the merciless Watson.6.King Richard in his gluttony never sat at a table more sumptuous than ours was three times a day…We had abundant food on the island, and even the meals enjoyed by King Richard, who was famous for his love of food, couldn^t possibly compare with ours.7.Despite the unrelenting heat, we were happy to be let off from our hours of school indoors, sessions which our mother kept every day, rain or shine.Although it was very hot outside in the sun, we were happy to be dismissed from my mothers sessions indoors, we would have to read and write with her every day no matter what the weather was like.Unit3l....even droughts, floods, and heat waves may become unwitting acts of man.What people do may unintentionally cause droughts, floods, and heat waves.2.But this image, now repeatedly thrust before us in photographs, posters, and advertisements, is misleading.The Earth we see in photos, posters, and ads, which appears so beautiful, is not the true reflection of the world we live in, such image lulls us into complacency.3.The technosphere has become sufficiently large and intense to alter the natural processes that govern the ecosphere.Human activities have taken place over such large areas and with such intensity that they have already caused disastrous effects on ecology.4....which could establish itself only because it fitted properly into the preexisting system.The fish could play its role because it became a necessary link with the processes preceding it and the processes following it in the ecological system.5.Defined so narrowly, it is no surprise that cars have properties that are hostile to their environment.When cars are produced to serve such narrow purposes, it is not surprising that some of their characteristic qualities are harmful to the environment.6.Yields rose, but not in proportion to the rate of fertilizer application...The farmer applied more and more fertilizer, and the production did rise but did notincrease at the same rate of the fertilize匚7...their waste is flushed into the sewer system altered in composition but not in amount at treatment plant…People eat plants and animals, and their waste is flushed into the sewer system. After being processed, the waste is still waste, the residue will go into rivers, oceans, and will have harmful effect on the aquatic ecosystem.8.Left to their own devices, ecosystems are conservative...If the ecosystems are not upset by outside intrusion, they will remain the same with very little change9.In contrast to the ecosphere, the technosphere is composed of objects and materials that reflect a rapid and relentless process of change and variation.The characteristics of the objects and materials in the technosphere are rapid change and great variety.10.But this is done only at the cost of understanding.If we take side in the war of the two words, we are doing so at the risk of failing to have a clear understanding of the nature and cause of the war, thus, we lose the chance to really solve the grave environmental crisis.Unit 4 Nettles1.How all my own territory would be altered, ad if a landslide had gone through it and skimmed off all meaning except loss of Mike.The impact of Mike's leaving on my life was beyond my imagination.

All my thoughts were about loss of Mike.2.During that time of life that is supposed to be a reproductive daze, with the woman's mind all swamped by maternal juices, we were still compelled to discuss Simone de Beauvoir and Arthur Koestler and "The Cocktail Party11.At that time, we were young mothers, and we were supposed to lead a terribly busy life full of confusion and bewilderment caused by giving birth to and raising babies, and our minds were supposed to be fully occupied by how to feed the babies and things like that. However, in the midst of all this we still felt the need to discuss some of the important thinkers of our time like Simone de Beauvoir and Arthur Koestler and T. S. Eliots sophisticated work "The Cocktail Party n.3•…I would be frightened, not of any hostility but of a kind of nonexistence.I would be frightened, and my fear was not caused by my neighbor's visibly hostile and violent way of life, but by a kind of formless and hidden emptiness and meaninglessness of human existence.

Writing Practicel. l) Computers are advanced machines that can store and recall information at very high speed. Computers are easy and interesting to use; however, some people are afraid of computers. I used to be afraid of computers, too, because of the fear of failure and because I knew nothing about Programming. But actually I have learned that the procedures of working on computers are very easy.2) When we were very young, we believed that parents could do no wrong. Indeed, they seemed to us to be perfect human beings who knew all the answers to our problems and who cou1d solve any problems that we had. However, as we grow older, we find that parents can make mistakes, too.3) Today's children are our future men and women. They will become the dominant force one day. If they receive proper guidance and have a nice childhood, they will contribute immeasurably to our society after they have grown up. In other words, today's children are going tohave a significant impact on our society in the future; therefore, parents should not neglect the proper conditions that children need during their childhood.2.(略)Key to supplementary readingA l.D 2.D 3.C 4.B 5.D 6.B 7.A 8.DB l.F 2.F 3.T 4.F 5.F 6.T 7.T 8.F 9.T l0.T参考译文社会服务经历时大学生的影响琳达J 萨克斯大学期间，参加社会服务的学生比不参加社会服务的学生更能提高自己的领导能力和社交方面的自信。

community where Rogers lived. Nobody knew who had committed it, but the police suspected Rogers, because his history of violating the law and committing crimes could be checked in the country court. Besides, in the police's eyes, Rogers ranked as one of the most dangerous figures in the country, and must be carefully dealt with. So he was summoned to appear in court the next Friday. He had been out of employment for several months. Needless to say, he could not afford to ask for a lawyer, but he hoped that someone was willing to provide him with free legal consulting service through telephone, so that he could defend himself in court.7Vocabulary work11.die down2.licked3.shrewd4.choked5.In Brief6.for one7.a dispatch8.facilities9.publicity 10.earn a living 11.enterprise 12.agent 13.accusation 14.transport15.as far as16.rumor21.bound up with2.proportion3.elapsed4.first and last5.going through6.rescued7.substantialarre9.illegal 10.scheme 11.foresee 12.expand 13.slips 14.be caught in31.The sudden disappearance of their guide puzzled the tourists.2.He was a lively and interesting speaker,but his last remarks apparenty had no connection with the begining of his speech.3.The accusation against the candidate was that he broke his promises even before he was in office.4.She had intended to spend only one year studying in Germany,but four years elapsed before she returned home.5.The young entrepreneur was too shrewd to get involved in that risky business venture.41.played up2.played upon3.played off4.played down5.played at6.playing around7.played with8.play back 9.played out 10.was dying for 11.way dying off 12.died out 13.died down14.died away15.from diedCLoze1.residing2.uncle3.enough4.waste5.money6.as7.answer8.deep-freeze9.undertook10.until 11.defrost 12.when 13.which 14.his 15.in 16.left 17.more 18.rest19.paying20.to 21.but 22.next 23.only.Error Correction1.intentions --whose intentions2.himself--herself3.entitling--entitled4.only--only to5.Any--Every6.down--/7.was--were8.As--If9.Of--Upon10.baffling--baffledTranslation1.In brief, these lab facilities are too expensive.

But if we take some decisive action in this aspect, the prospect that we long for will appear before us. In other words, our future is in our own hand's to a great extent; our future is in fact the product of the joint decisions we make today. Needless to say, our present action will make certain prospect more likely to come true compared with some other prospects.Some scholars noticed that science fiction writers devoted their lives to showing what kind of future world would result from certain actions of human genius. They studied the excellent science fictions published in recent years, and got the conclusion that science fiction could reveal to us what would happen in the future and help us from a future world that we long for,What's interesting is that science fiction courses are offered in many colleges and universities on the grounds that science fiction is the bridge between science and art.9Vocabulary work11.submerged2.eased off3. enlarged4. burnt out5.make room for6.spit7.suck8.overdue9.at hand10.wreck11.vogue 12.rust 13.terror 14.digest 15.flash 16.turn back21.gets through2.but then3.transient4.at hand5.surrender6.pedestrian7. looked up to8.riddled with9.played a part 10.run out of time11.enlarge 12.vogue 13.optimist or a paragon 14.terror31.Overwork left him a wrech and his doctor ordered him to take a vacation.2.Ruth has every reason to think that her promotion is overdue.3.The heavy fog kept the plane from langding and it was how running out of fuel.4.Lst year's bad weather played a great part in the food prices which were pushed higher.5.Why don't you wait until traffic eases off.41.run out2.were run down3.running through4.is running out5.ran across6.run after7.run down8.are running out of9.ran away 10.be run away11.ran into 12.ran 13.run for 14.falling apart 15.fell away 16.fall back on17.am falling behind 18.falls for 19.falling in 20.fell off21.have fallen out22.fell out 23.has fallen throughCloze1.about2.going3.how4.what5.nothing6.Yet7.else8.spending9.too 10.off 11.on 12.do 13.More 14.less 15.like 16.thoughts 17.says 18.in19.if 20.failing 21.down 22.vision 23.claiming 24.sounds 25.far e 27.which 28.health 29.who 30 soError Corrention1.as -/2.attracting -distracting3.task-task in4.when-before5.them-it6.processions-processes7.nevertheless-instead8.and - yet9.Other -Another10.quick-quicklyTranslation1.James removed the books on the small stable to make room for the TV set.2.It is reported that the fire had burned out before firemen arrived there.3.Bob sat down and get ready to write.

But in fact teachers seldom mention the main controversial issues in the contemporary academic field even though they will teach them some scientific controversies in the past. This is concerned with the science teachers who are unwilling to introduce the current debates to students, for fear that students can't readily grasp the significance of the current academic debates if they don't first master the "fundamental knowledge."However things are different.College students are able to think over these controversies and understand what they are about by capitalizing on the knowledge they have acquired. Then what can college students learn from the current controversies concerned with the unknown world?First, it can stimulate their interest and attract their attention to watch those wise and imaginative scientists debating about the future world.Second, they will come to know that many important questions concerning our knowledge on nature are still a mystery. This will lead to the recognition of ignorance which will, in turn, urge them to make greater efforts in the scientific research.。
