Then mark the corresponding letter with a single line through the center (on Answer Sheet I).Scientists searching for precious metals have turned to the ocean floor, where natural chimneys are spewing out a metal-enriched black dust containing particles of gold, silver and zinc.Scientists 31 these hot springs are recreating the process which, billions of years ago, created 32 metal deposits now found on land.The discovery is giving geologists a 33 into the earth’s early history and fuelling some new theories on origin of life.It also has huge implications for 34 companies.Geologists are just beginning to understand how these chimneys, 35 clusters of sulphur and minerals, are formed, and what makes them spew out the mineralized dust.At present it is not commercially 36 for mining companies to operate beneath the sea, although some scientists believe the “black smokers”, 37 known as active mineralizing systems, will be a major—and renewable —source of metals in the next decade.38 the meantime, mining companies are using the ocean-floor research to locate similar deposits on land.“The hottest thing in the mining research game right now is the39 within the past few years of mineral deposits currently forming—in front of our eyes—on the ocean floor,” said Dr. Joseph Fox, a Montreal (加拿大蒙特利尔) geologist.Canada has mined some of the richest copper, zinc and gold 40 in the world. In the past year, mining companies have used knowledge about where mineral formations 41 on the ocean floor to find the deposits on land.Geologists are excited because, 42 metal deposits on land, which are two or three billion years old, the undersea deposits keep 43 themselves.“It’s really incredible to think that we have a renewable metal resource44 we’ve been taught to think of metal resources as non-renewable,” Fox said.The 30-foot-high (10-metre) chimneys or vents, 45 in 1979, are found along fractures in the ocean’s crust.Scientists believe the deposits form when cold sea-water seeps into the fractures, leaving metals 46 it is drawn down.As the water travels in the direction of the earth’s core, it47 up. Eventually, the hot water rises, carrying with it the hot metal sulphide 48 the ocean floor.When the hot sulphide meets the cold sea water, a thick black smoke-like substance is formed, spewing out of vents in built-up deposits of 49 .The particles in the smoke eventually 50 on the ocean floor, forming vast solid sheets of metal sulphide. 31.

For each of them there are four choices marked A, B, C and D. You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the center (on Answer Sheet I). Passage OneQuestions 51 to 55 are based on the following passage.Professor Smith recently persuaded 35 people, 23 of them women, to keep a diary of all their absent-minded actions for a fortnight. When he came to analyze their embarrassing lapses in a scientific report, he was surprised to find that nearly all of them fell into a few groupings. None did the lapses appear to be entirely random.One of the women, for instance, on leaving her house for work one morning threw her dog her earnings and tried to fix a dog biscuit on her ear. “The explanation for this is that the brain is like a computer,” explains the professor. “People programme themselves to do certain activities regularly. It was the woman’s custom every morning to throw her dog two biscuits and then put on her earrings. But somehow the action got reversed in the programme.” About one in twenty of the incidents the volunteers reported were these “programme assembly failures.”Altogether the volunteers logged 433 unintentional actions that they found themselves doing—an average of twelve each. There appear to be peak periods in the day when we are at our zaniest. These are two hours some time between eight a.m. and noon, between four and six p.m. with a smaller peak between eight and ten p.m. “Among men the peak seems to be when a changeover in brain ‘programmes’ occurs, as for instance between going to and from work.” Women on average reported slightly more lapses—12.5 compared with 10.9 for men probably because they were more reliable reporters.A startling finding of the research is that the absent-minded activity is a hazard of doing things in which we are skilled. Normally, you would expect that skill reduces the number of errors we make. But trying to avoid silly slips by concentrating more could make things a lot worse—even dangerous.51. In this study Professor Smith asked the subjects _______.A. to keep track of people who tend to forget thingsB. to report their embarrassing lapses at randomC. to analyze their awkward experiences scientificallyD. to keep a record of what they did unintentionally52. Professor Smith discovered that _______.A. certain patterns can be indentified in the recorded incidentsB. many people were too embarrassed to admit their absent-mindednessC. men tend to be more absent-minded than womenD. absent-mindedness is an excusable human weakness53. “Programme assembly failures (Sentence 6, Paragraph 2)” refers to the phenomenon thatpeople _______.A. often fail to programme their routines beforehandB. tend to make mistakes when they are in a hurryC. unconsciously change the sequence of doing thingsD. are likely to mess thing up if they are too tired54. We learn from the third paragraph that _______.A. absent-mindedness tends to occur during certain hours of the dayB. women are very careful to perform actions during peak periodsC. women experience more peak periods of absent-mindednessD. men’s absent-mindedness often results in funny situations55. It can be concluded from the passage that _______.A. people should avoid doing important things during peak periods of lapsesB. hazards can be avoided when people do things they are good atC. people should be careful when programming their actionsD. lapses cannot always be attributed to lack of concentrationPassage TwoQuestions 56 to 60 are based on the following passage.The two claws of the mature American lobster are decidedly different from each other. The crusher claw is short and stout; the cutter claw is long and slender. Such bilateral asymmetry, in which the right side of the body is, in all other respects, a mirror image of the left side, is not unlike handedness in humans. But where the majority of humans are right-handed, in lobsters the crusher claw appears with equal probability on either the right side or left side of the body.Bilateral asymmetry of the claws comes about gradually. In the juvenile fourth and fifth stages of development, the paired claws are symmetrical and cutter like. Asymmetry begins to appear in the juvenile sixth stage of development, and the paired claws farther diverge toward well-defined cutter and crusher claws during succeeding stages. An intriguing aspect of this development was discovered by Victor Emmer. He found that if one of the paired claws is removed during the fourth or fifth stage, the intact claw invariably becomes a crusher, while the regenerated claw becomes a stutter. Removal of a claw during a later juvenile stage or during adulthood, when asymmetry is present, does not alter the asymmetry; the intact and regenerated claws retain their original structures.These observations indicate that the conditions that trigger differentiation must operate in a random manner when the paired claws are intact, but in a nonrandom manner when one of the claws is lost. One possible explanation is that differential use of the claws determines their asymmetry. Perhaps the claw that is used more becomes the crusher. This would explain why, when one of the claws is missing during the fourth or fifth stage, the intact claw always becomes a crusher. With two intact claws, initial use of one claw might prompt the animal to use it more than the other throughout the juvenile fourth and fifth stages, causing it to become a crusher. To test this hypothesis, researchers raised lobsters inthe juvenile fourth and fifth stages of development in a laboratory environment in which the lobster could manipulate oyster chips. (Not coincidentally, at this stage of development lobsters typically change from a habitat where they drift passively, to the ocean floor where they have the opportunity to be more active by borrowing in the substrate.) Under these conditions, the lobsters developed asymmetric claws, half with crusher claws on the left, and half with crusher claws on the right. In contrast, when juvenile lobsters were reared in a smooth tank without the oyster chips, the majority developed two cutter claws. This unusual configuration of symmetrical cutter claws did not change when the lobsters were subsequently placed in a manipulable environment or when they lost and regenerated one or both claws.56. The passage is primarily concerned with _______.A. drawing an analogy between asymmetry in lobsters and handedness in humansB. discussing a possible explanation for the way bilateral asymmetry is determined inlobstersC. explaining differences between lobsters’ crusher claws and cutter clawsD. developing a method for predicating whether crusher claws in lobsters will appear onthe left or right side57. Which of the following experimental result, if observed, would most clearly contradict thefindings of Victor Emmer?A. A left cutter like claw is removed in the fifth stage and a crusher claw develops on theright side.B. A left cutter like claw is removed in the fourth stage and a crusher claw develops on theleft side.C. A left cutter like claw is removed in the sixth stage and a crusher claw develops on theright side.D. A left cutter like claw is removed in the fourth stage and a crusher claw develops on theright side.58. It can be inferred from the passage that one difference between lobsters in the earlier stagesof development and those in the juvenile fourth and fifth stages is that lobsters in the earlystages are _______.A. more likely to regenerate a lost clawB. more likely to replace a crusher claw with a cutter clawC. likely to be less symmetricalD. likely to be less active59. Which of the following conditions does the passage suggest is a possible cause for the failureof a lobster to develop a crusher claw?A. The loss of a claw during the third or earlier stage of development.B. The loss of a claw during the fourth or fifth stage of development.C. The loss of a claw during the sixth stage of development.D. Development in an environment devoid of material that can be manipulated.60. The author regards the idea that differentiation is triggered randomly when paired clawsremain intact as _______.A. irrefutable considering the authoritative nature of Emmer’s observationsB. contradictory to conventional thinking on lobster-claw differentiationC. likely in view of present evidenceD. purely speculative because it is based on scattered research and experimentationPassage Threephysical chemist who divides his time between the University of California, Berkeley, and the Lawrence Berkeley National Lab, has a goal to create a computer model of how the cell works so that someday he’ll be able to design his own cells from scratch.It’s a daunting task. A single enzyme in a liver c ell may be controlled by as many as 14 different regulatory processes. Multiply that by thousands of interconnected chemical reactions operating simultaneously in billions of cells, and you’ve got one incredibly complex system.Enter a computer program called SPICE (Simulation Program for Integrated Circuit Evaluation), developed at the University of California, Berkeley, in the 1970s. SPICE allowed engineers to analyze their electronic circuits and predict, more or less accurately, how they would work before they were actually built. There would always be problems to iron out, but at least the program pointed chip designers in the right direction.Arkin is developing a similar program he calls bio/SPICE that he hopes will do for the cell what SPICE did for the chip. His first targets are simple bacteria. “They’re still complicated enough that we get depressed,” Arkin admits with a laugh. But he has already had some success grouping reactions together by the kinds of jobs they do. And, sure enough, some of them bear a remarkable resemblance to the gates and switches of an electronic circuit.Of course, no one knows for sure whether Arkin or anyone else will be able to develop a working computer model of the cell. But it’s the sort of project that could keep sc ientists busy for another 100 years.61. In the first paragraph, “… what makes them tick …” means _______.A. why something operates as it doesB. what makes cells thick and then block in blood streamsC. what cells consist ofD. how cells are born and die62. What do we learn from the passage?A. What Arkin intends to achieve is unprecedented.B. Arkin has just followed the past biologists’ footprints and nothing newC. Arkin, based on the work of others, wants to build a computer model of his ownD. To de sign one’s own cells is what biologists have dreamed of for almost a century.63. Which of the following adjectives can best describe the task Arkin is engaged in?A. Challenging.B. Delicate.C. Simple.D. Depressing.64. How is Arkin getting on with his work?A. Getting nowhere.B. Getting somewhere.C. There is a bigger breakthrough.D. There is a remarkable resemblance found in his research.65. What is the author’s attitude towards Arkin’s research?A. Suspicious.B. Positive.C. Negative.D. Indifferent.Passage FourGetting ready to go back to school in the good old days of, say, 1998 meant a few trips to the mall and a quick check of the bus route. This year, for many parents, there are some new things to remember: The teacher’s e-mail address, the school’s website and which night online homework helps chat will be offered. “The 1999-2000 school year will be the one when the majority of parents really feel the Internet’s influence on their children’s education at the everyday level,” says Jonathan Carson, chairman of the Family Education Co., which offers a parenting website at and a framework for local schools to create and maintain their own sites.This year promises to show a quantum leap in the spread of school technology: Parents in many districts can expect to be able to check the school lunch menu, read class notes, see activity calendar and view nightly homework assignments—all online. “The schools are wired,” says Carson. “A majority of parents now have access and the educators are ready to go.”Over the summer, parents of high school German students in Ithaca, N.Y. got to be part of a class to Europe, through their home computers. The class brought a digital camera and laptop with them to Germany and documented their visit on their web page. Hazy Ash, father of 16-year-old traveler Bria n, found it reassuring to see his son’s smiling face from half a world away. Before their kids left, parents had checked the site for scheduling information, a list of activities and advice on cultural differences.When it’s designed well, a district, school or classroom website can change the relationship between the parents and the school, says Cynthia Lapier, Ithaca’s director of information and instructional technology. “The more you can involve parents in school, the better,” Lapier says. “The technology gives us another way to reach them, especially parents of secondary school students, who tend to be less involved.”Ithaca High School physics teacher, Stever Wirt, gets e-mail from parents regularly, some from the parents he believes might otherwise not pick up the phone with a concern. Using software called Blackboard Course Info, Wirt conducts online chats with his students often reviewing for a quiz or discussing homework problems.The way things are going, by the end of this year, many parents may be fully converted—and in fact dependent upon their school’s technological capabilities. At a recently wired school in Novi, Michigan, the school webmaster was just a few hours late posting the lunch-menu calendar on the website. In that time, more than a dozen parents called him by telephone to request the information. “A year ago, it never would have been there,” says Carson. And now parents are finding it’s tough to get by without it.在像1998年那样经济繁荣的岁月里，父母为孩子开学返校需要做的准备工作包括去逛几次商场和文具店, 快速核实一下校车路线。
