第3题：
We know a computer is a machine that processes data(stored in main memory)into information, under control of a stored program. We also know that, internally, a computer is a binary machine; thus the data and the program instruictions must be stored in binary form. Characters are represented in(71). Numbers are stored as binary numbers, with each bit's positional value significant. A computer's main memory is divided into bytes, words or both(depending on the system), and each of these basic storage units is assigned an(72). Using this address, the processor can read or write selected bytes or words.
The processor consists of a clock, an instruction control unit, an arithmetic and logic unit, and registers. Once a program is stored in main memory, the processor can begin to execute it. During(73), the instruction control unit fetches an instruction from main memory; during(74), the arithmetic and logic unit executes it.

The Weight Experiment
Nicola Walters has been taking part in experiments in Scotland to discover why humans gain and lose weight. Being locked in a small room called a“calorimeter”（热量测量室）is one way to find out.
1. The signs above the two rooms read simply“Chamber One”and“Chamber Two”.These are the calorimeters:4m by 2m white-walled rooms where human volunteers are locked up in the name of science .Outside these rooms another sign reads“Please do not enter work in progress” and in front of the rooms advanced machinery registers every move the volunteers make.Each day,meals measured to the last gram are passed through a hole in the wall of the calorimeter to the resident volunteer.
2. Nicola Walters is one of twenty volunteers who,over the past eight months,have spent varying periods inside the calorimeter. Tall and slim,Nicola does not have a weight problem,but thought the strict diet might help with her training and fitness programme.As a self-employed community dance worker,she was able to fit the experiment in around her work .She saw an advert for volun- teers at her local gym and as she is interested in the whole area of diet and exercise,she thought she would help out.
3. The experiment on Nicola involved her spending one day on a fixed diet at home and the next in the room.This sequence was repeated four times over six weeks.She arrived at the calorimeter at8:30 am on each of the four mornings and from then on everything she ate or drank was carefully measured.Her every move was noted too,her daily exercise routine,timed to the last second.
At regular intervals,after eating,she filled in forms about how hungry she felt and samples were taken for analysis.
4. The scientists help volunteers impose a kind of order on the long days they face in the room. “The first time,I only took one video and a book,but it was OK because I watched TV the rest of the time,”says Nicola. And twice a day she used the exercise bike. She pedaled（踩踏板） for half an hour,watched by researchers to make sure she didn't go too fast.
5. It seems that some foods encourage you to eat more,while others satisfy you quickly.Volun- teers are already showing that high-fat diets are less likely to make you feel full.Believing that they may now know what encourages people to overeat,the researchers are about to start testing a high-protein weight-loss diet. Volunteers are required and Nicola has signed up for further ses- slons。Volunteers have to get prepared for the time in the calorimeter______.
A: the volunteers do
B: because she does not have a weight problem
C: because the life there can be very boring
D: make people overeat
E: because she was her own boss
F: after passing a high-protein test答案：C解析：本文的主题是体重实验，主要谈哪些活动可以减轻人的体重。实验室里有专门的热量测量室。第一段主要介绍热量测量室的有关情况，选项C的意思是“热量测量室是什么？”作为第一段的小标题最合适，故选C。
第二段主要讲Nicola作为一名志愿者，在热量测量室进行了多次实验，文章说她到这里来的主要目的不是减肥，而是看看这里的饮食和活动对健身如何有益，因为她自己是搞跳舞的，她认为通过参加这里的活动会给自己的工作带来益处。选项F的意思是 “她为什么来参加实验？”正好概括了这段的意思，所以选F。
第三段主要介绍针对Nicola安排的实验的详细情况。与选项B的意思相符，故选B。
第四段主要介绍志愿者接受实验时如何打发自己的时间，主要是看看电视或看书。选项E中的kill the time就是“打发时间”的意思，与第四段意思相符，故选E。
此句的意思是实验室外面的机器都记录了什么？根据第一段的介绍，显然是志愿者所做的各种活动的情况等，故选A。
此句问为什么Nicola有时间来参加实验，文章提到她是自雇的社区跳舞工作者，可以自由安排自己的时间，故选E。
此句问的是为什么志愿者要对在实验室里的时间做好准备，文章也提到了做实验时是很枯燥的，如果接受实验，就要做好如何打发时间的心理准备，选项C补到句子中意思合适，故选C。
题句问的是实验表明，高脂肪的饮食会导致什么？文章最后谈到，志愿者发现实验室里安排的这些高脂肪食物让人感觉吃不饱，所以导致人们吃得过多。因此选D。 -

Auctions
Auctions are public sales of goods,conducted by an officially approved auctioneer. He or she asks the assembled crowd in the auction-room to make offers,or"bids",for the various items on sale.He encourages buyers to bid higher figures,and finally names the highest bidder as the buyer of the goods.This is called"knocking down"the goods,for the bidding ends when the auctioneer bangs a small hammer on a table at which he stands.This is often set on a raised platform called a rostrum.
The ancient Romans probably invented sales by auction,and the English word comes from the Latin auction,meaning"increase".The Romans usually sold in this way the spoils taken in war; these sales were called"sbu hasta",meaning"under the spear",a spear being stuck in the ground as a signal for a crowd to gather. In the eighteenth and nineteenth centuries goods were often sold "by the candle",a short candle was lit by the auctioneer;and bids could be made while it stayed alight.
An auction is usually advertised beforehand with full particulars of the articles to be sold and where and when they can be viewed by possible buyers.If the advertisement cannot give full details, catalogues are printed,and each group of goods to be sold together,called a"lot",is usually given a number. The auctioneer need not begin with Lot 1 and continue in numerical order. He may wait until he registers the fact that certain dealers are in the room and then produce the lots they are likely to be interested in.The auctioneer's services are paid for in the form of a percentage of the price the goods are sold for. The auctioneer therefore has a direct interest in pushing up the bidding as high as possible.
Practically all goods whose qualities vary are sold by auction.Among these are coffee,hides, skins,wool,tea,cocoa,furs,spices,fruit and vegetables and wines.Auction sales are also usual for land and property,antique,furniture,pictures,rare books,old china and similar works of art. The auction rooms at Christie's and Sotheby's in London and New York are world famous.The auctioneer may decide to sell the"lots"out of order.
A:Right
B:Wrong
C:Not mentioned答案：A解析：文章第二段前面提到“The Romans usually sold in this way the spoils taken in war”，他们拍卖过战利品，但是没有详细说明哪些战利品，所以该判断文章没有提到，选C。
第二段的最后一句说到“bids could be made while it stayed alight”。只要蜡烛没有熄灭就仍然可以竞价，即限制出价的时间，所以选A。
该判断正确。第三段第三句提到“The auctioneer need not begin with Lot 1 and continue in numerical order”。不需要按照批次拍卖，拍卖师可以决定拍卖的顺序，所以选A。
该判断错误。第一段的第三句“finally names the highest bidder as the buyer of the goods”。出价最高的买主得到商品，并非最低价，所以选B。
文章最后一段虽然有提到“china”，但是它是小写的单词，意思是“瓷器”，文章其他地方没有涉及中国的拍卖，更无从得知中国什么时候开始有了拍卖行，因此选C。
文章的第一段提到解释了为什么叫“敲定”,"for the bidding ends when the auctioneer bangs a small hammer on a table"，拍卖结束后拍卖师会在桌面敲击一个小锤，以示买卖成交。因此A正确。
第二段的首句“The ancient Romans probably invented sales by auction”，拍卖或许是古罗马人发明的，文章最后一句虽然提到了英国，但只是说到了英国著名的拍卖行，并没有提到英国人发明了拍卖方式。所以选B。 -

问答题Practice 2Thoughts in Westminster Abbey When I am in a serious humour, I very often walk by myself in Westminster Abbey; where the gloominess of the place, and the use which it is applied, with the solemnity of the building, and the condition of the people who lie in it, are apt to fill the mind with a kind of melancholy, or rather thoughtfulness, that is not disagreeable. I yesterday passed a whole afternoon in the churchyard, the cloisters, and the church, amusing myself with the tombstones and inscriptions that I met with in those several regions of the dead. Most of them recorded nothing else of the buried person, but that he was born upon one day, and died upon another：the whole history of his life being comprehended in those two circumstances, that are common to all mankind. I could not but look upon these registers of existence, whether of brass or marble, as a kind of satire upon the departed persons；who had left no other memorial of them, but that they were born and that they died. They put me in mind of several persons mentioned in the battles of heroic poems, who have sounding names given them, for no other reason but that they may be killed, and are celebrated for nothing but being knocked on the head. The life of these men is finely described in holy writ by ‘the path of an arrow’, which is immediately closed up and lost. Upon my going into the church, I entertained myself with the digging of a grave；and saw in every shovelful of it that was thrown up, the fragment of a bone or skull intermixt with a kind of fresh mouldering earth, that some time or other had a place in the composition of a human body. Upon this I began to consider with myself what innumerable multitudes of people lay confused together under the pavement of that ancient cathedral；how men and women, friends and enemies, priests and soldiers, monks and prebendaries, were crumbled amongst one another, and blended together in the same common mass；how beauty, strength, and youth, with old age, weakness and deformity, lay undistinguished in the same promiscuous heap of matter.正确答案： 参考译文
威斯敏斯特教堂内的遐想 每当心情沉重的时候,我总是独自一人去威斯敏斯特教堂;那里肃穆的气氛,教堂特有的神圣,庄重的建筑,在那里安息的人们的身份地位,无不给人的心里注满一种忧郁,或不妨说令人沉思,令人欣然。昨天我在教堂草地、回廊和教堂里度过了整整一个下午,在好几个墓区里,打量墓碑和碑文,聊以自娱。大部分的墓碑上只刻着死者姓名和生卒年月:人们对其一生的了解也只在于人类所共有的生死两字。对于那些逝去的人们的生死记录,不管是刻在铜牌上还是刻在大理石碑上,我都不由自主地将它们看作是对死者的一种讽刺;他们没有留下任何别的记录,只是生与死。他们使我想到了英雄诗歌中描写战争时提到的几个人物,他们有响亮的名字,不为别的原因,只是因为他们可能战死,只是因为他们的死亡而为人纪念。圣经中的句子“如箭飞过”恰如其分地描写了这些人的一生:一闪而过,不见踪影。
我走进教堂,观看别人挖一座坟墓;只见挖出来的每一铲新的腐土中,都混杂着骨头或头颅的碎块,曾几何时,这些碎块还是人身体的一部分呢。看见这个情景,我暗自思忖,在这座古老的大教堂的路底下,混埋着何等众多的人啊;男人和女人,朋友和敌人,牧师和士兵,修士和受俸牧师,全都变成了碎块,混在一起;美丽、强壮、年轻的人和年老力衰、畸形的人,毫无区别地杂处在一堆之中。解析： 暂无解析 -

单选题Passage2The way people work has changed. The increasing use of technology presents new and continual challenges to small and large businesses，employees and managers，teachers and students.Everyone，it seems，is being affected by the technological revolution. Store clerks，for example，now use increasingly complex computerized cash registers，while university professors must learn to adapt their teaching skills in order to lead distance learning course.In today's world，training and learning do not stop when we finish school；they must now continue throughout our working lives. The Hong Kong government conducted a survey on the employment concerns，and training needs of its workforce. For many managers and other professionals the biggest challenge，as well as change，in the workplace，was the increased use of computers and computerized machinery or equipment. The need for experienced employees who could use this kind of equipment rose drastically. Many of those in the workplace at this time experienced changes in job requirements and had to attend job-related training or re-training courses.The changing work environment is also affecting education and how we learn. In Finland, a report on strategies for education and training in the information age discussed the changing roles of both teacher and student. With the increased use of technology and the growth of distance learning, the teacher has become more of a tutor who guides a student, rather than a lecturer. In turn, the student has to take more responsibility for his or her learning in the absence of direct teacher contact. The report also stressed that high school and university students should learn computer skills in order to cope with the demands of the future workplace.The Finnish report also highlighted the need for teacher training, and re-training, and suggested that the salaries and job descriptions of teachers be reviewed because of future demands expected in their jobs. Previously university professors may have held lectures between the weekday hours of 9:00A.M. and 5:00 P.M. in large halls filled with students. Now, they may spend part of their day lecturing larger groups of students on campus, and then conduct afternoon or evening classes online, with students in five different countries.As technologies grow and develop, ongoing training will continue to be necessary. To be successful in the workplace, people will not stop learning when they leave school-lifelong learning will become a way of life.How did the changing work environment change the role of the teacher according to the Finnish report?Athe teacher became more of a tutor rather than a lecturer.
Bthe teacher had to learn more strategies for distance teaching.
Cthe teacher had to learn how to teach students without direct contact.
DThe teacher should learn computer skills to cope with the demands of the future workplace.

In recent years, one of the more popular topics for panel discussions at computer conferences and trade(61)has been the "RISC versus CISC" debate.RISC processors feature a small number of instructions that each executes in(62)machine cycle.

第23题：
问答题Research published in May 1998 by the Department of the Environment, Transport and the Regions (DETR) showed that reducing coastal and river pollution and ensuring a reliable water supply were among the top environmental priorities for the public. All discharges to water in the UK require the consent of the appropriate regulatory authority. In England and Wales the Environment Agency’s principal method of controlling water pollution is through the regulation of all effluent discharges, including sewage, into groundwater, and inland and coastal waters. The Agency maintains public registers containing information about water quality, discharge consents, authorizations and monitoring. Applicants for consents to discharge have the right of appeal if they are dissatisfied with the Agency’s decision; most of these appeals are dealt with by the Planning Inspectorate, an executive agency of the DETR. In Scotland control is the responsibility of the Scottish Environment Protection Agency (SEPA), and most appeals are dealt with by the Scottish Office. In Northern Ireland the Environment and Heritage Service is responsible for controlling water pollution. In 1997, there were 4,717 cases in England and Wales of discharges exceeding their consented limits, including a number of offences by water companies discharging insufficiently treated sewage. The majority of these breaches did not cause any significant environmental damage. However, the Environment Agency did bring 65 cases to court, of which 61 were successful, resulting in fines ranging from ￡ 440 to ￡ 12,000 and one prison sentence of two months. In Scotland, there were 2,734 pollution incidents in 1997; SEPA seeks prosecution in all significant cases. In 1997 and 1998, the Government introduced statutory Environmental Quality Standards (EQSs) for 33 substances in water. The new regulations give legal force for the first time to standards for some of the most dangerous pollutants found in the aquatic environment. In the UK, 96 percent of the population live in properties connected to a sewer, and sewage treatment works serve over 80 percent of the population. In England and Wales, the water industry is committed to an investment programme of some ￡ 11,000 million over ten years for improvements to water quality. Progressively higher treatment standards for industrial waste effluents and new measures to combat pollution from agriculture are expected to bring further improvements in water quality. In Scotland, responsibility for the provision of all water and sewerage services lies with three Water and Sewerage Authorities, covering the north, east and west of the country.正确答案： 【参考译文】
根据英国环境交通部于l998年5月公布的研究报告,减少沿海水域与河流的污染,保证供应安全用水,乃是广大公众在环保方面的当务之急。
在英国,向水中倾倒任何东西,都需征得有关管理部门的同意。在英格兰和威尔士,环境署控制水污染的主要方法是监控一切流入地下水及内陆和沿海水域的废水,包括污水。环境署存有公开的记录,记载着水质、排放许可、授权单位、监督情况等事项。申请排放许可者如对环境署的决定不满,有权上诉,大多由计划督察团接受处理——督察团是部属的一个执行机构。在苏格兰,是由苏格兰环保署(SEPA)负责监控,上诉大多由驻苏格兰办事处接受处理。在北爱尔兰,水污染由环境与遗产局负责监控。
1997年,在英格兰和威尔士共发生4717起超过许可限度的排污事件,其中有一些是水公司的过错,这些公司排放了未经充分处理的污水。这些违规行为绝大部分都没有对环境造成重大危害。然而,环境署也的确将65起违规事件送上法庭,其中61起环境署胜诉,判处的罚款自440镑至12000镑不等,还有一起判处败诉方两个月徒刑。在苏格兰,1997年共发生污染事件2734起;苏格兰环境保护署对情节严重者均予起诉。
1997和1998年,政府实行法定环境质量标准,涉及水中33种物质。新规定使得关于在水中发现的几种最危险的污染物的标准第一次具有法律效力。
在英国,96%人口的住宅与下水道系统相连,污水处理厂能为80%以上的人口服务。在英格兰和威尔士,水工业承诺在十年间将投资约110亿英镑,以改善水质。逐步提高工业废水处理标准,采取新措施以治理农业造成的污染,预计将会进一步提高水质。在苏格兰,三个给水排污管理局负责给水和排污的事宜,分管全国的北部、东部和西部地区。解析： 暂无解析 -
