Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.How Should You Build up Your Vocabulary?A.Exactly what do you do during a normal day? How do you spend your time? Paul T. Rankin very muchwanted an answer to that question. To get it, he asked sixty-eight individuals to keep an accurate,detailed record of what they did every minute of their waking hours. When he consolidated (巩固) hisfindings, he discovered that the average individual spent 70 percent of his waking time doing one thingonly—communication. That meant either reading, writing, speaking or listening.B.Put that evidence alongside of the research findings uncovered by the Human Engineering Laboratories.In exploring aptitudes and careers involving, among other things, data from 30,000 vocabulary testsgiven yearly, they discovered that big incomes and big vocabularies go together. V ocabulary, more thanany other factor yet known, predicts financial success.C.And it all fits. Each word you add to your vocabulary makes you a better reader, writer, speaker andlistener. Furthermore, linguistic scientists are quick to point out that we actually think with words. Ifthat is so, new words make us better thinkers as well as communicators. No wonder more words arelikely to mean more money. What better reason for beginning right now to extend your vocabulary? D.Take reading. What exactly do you read? Common sense says you read words. Research confirms thatfact. “V ocabulary in context” contributes 39 percent to comprehension. That’s more than any other factor isolated and studied—even more than intelligence. And “ word discrimination” contributes more to speed of reading than any other factor—28 percent. In short, your efforts to improve vocabulary will payoff in both comprehension and speed.E.Suppose, as you’re reading along, you lumtebs across a strange word. Did you find yourself stoppingfor a closer look at lumtebs? Pardon the spelling slip. That’s actu ally the word stumble (偶然发现). The letter just got mixed around. Obviously you now know that strange words do slow you down—or even stop you completely. Furthermore, strange words hinder (妨碍) comprehension. Which is easier to understand, “eschew garrulity” or “avoiding talking too much”?F.What you need is a vital, dynamic approach to vocabulary building. Hybrid (混合种) corn combines thebest qualities of several varieties to ensure maximum productivity. A hybrid approach to vocabulary should, in the same way, e nsure maximum results. That’s why you should use the CPD formula.Through ContextG.When students in a college class were asked what should be done when they came across an unknownword in their reading, 84 percent said, “Look it up in the dictionary. “ If y ou do, however, you short-circuit the very mental processes needed to make your efforts most productive.H.But there’s another reason. Suppose someone asks you what the word fast means. You answer, “speedyor swift”. But does it mean that in such contexts as“fast color”, “fast woman”, or “ fast friend” ? And ifa horse is fast, is it securely tied or galloping (飞驰) at top speed? It could be either. It all depends. Onthe dictionary? No, on context—on how the word is actually used. After all, there are over twenty different meanings for fast in the dictionary. But the dictionary doesn’t tell you which meaning is intended. That’s why it makes such good sense to begin with context.Through Word PartsI.Now for the next step. Often unfamiliar words contain one or more parts, which, if recognized, providedefin ite help with meaning. Suppose you read that someone “ had a predilection for reading mysteries”.The context certainly isn’t too helpful. But do you see a prefix, suffix or root that you know? Well.there’s th e familiar prefix pre-, meaning “before”. Look back at the context and try inserting “before”.Reading mysteries apparently comes “before” other kinds of reading. Yes, a pre-dilection—or preference—is something put “before” something else. Or take the word monolithic. Try to isolate the parts. There is the prefix mono-, meaning “one”, and the root lith, meaning “ stone”. Finally, there’s the suffix -ic, meaning “consisting of”. Those three parts add up to this definition: “consisting of one stone”.J.To speed up your use of word parts, you will be introduced to the fourteen most important words in the English language. The prefix and root elements in those few words are found in over 14,000 words of desk dictionary size. With those amazingly useful shortcuts, you can build vocabulary, not a snail’s pace, one word at a time, but in giant strides, up to a thousand words at a time. Your second step, then, is to look for familiar word parts. If they do not give you exact meanings, they should at least bring you much closer.Through the DictionaryK.Now you can see why you should consult the dictionary last, not first. You’ve looked carefully at the context. You’ve looked for familiar word parts. Now you play Sherlock Holmes—an exciting role. You hypothesize. In light of context or word parts, you try to solve a mystery. What exactly does that strange word mean? Only after you go through the mental gymnastics to come up with a tentative definition should you open the dictionary to see if you’re right.L.After all, those first two steps or approaches spark a stronger than usual interest in that dictionary definition. You’re now personally involved. Did you figure out the word meaning? Your heightened interest will lead to a better memory of both word and meaning. It also encourages your development of the habits needed to accelerate your progress. And when you see in black and white the definition you had expected, what a feeling of accomplishment is yours. In that way, the CPD Formula provides the exact dynamic interplay of approaches for maximum effectiveness.M.Well, there it is, your new formula—Context, Parts, Dictionary. Use it! The exercises that follow will give you specific, step-by-step help in sharpening your awareness of contextual clues, learning the most useful word parts, and using the dictionary with increased accuracy and ease. The results will be like the money in the bank.31. When you refer to a dictionary for the meaning of “fast” in fast color, you will probably not get its exactmeaning.32. You can get the close meaning of an unfamiliar word by looking for the familiar parts in it.33. Performing a Context-Parts-Dictionary Formula exercise will gradually help you sharpen your awarenessof contextual clues.34. It is discovered that vocabularies and incomes are closely related.35. The best approach to vocabulary building is to use a CPD formula.36. You should n’t open the dictionary until you have gone through the mental gymnastics to come up with atentative definition.37. Seventy percent of the waking time of an average individual was spent on communication.38. A majority of students may choose to look up the dictionary if they come across a new word whilereading.39. “Word discrimination” is the biggest influencing factor to one’s reading speed.40. Your heightened interest will not only help you memorize word and meaning, but also develop your habits needed for the acceleration of your progress.Part ⅢReading Comprehension (Reading in Depth)Section ADirections: In this section, there is a passage with ten blanks. You are required to select one world for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please fill in each blank with a letter.You may not use any of the words in the bank more than once.The name Prometheus refers to a wise person who can foresee everything, and the name Epimetheus means the opposite, so he always regretted over what he had done. Prometheus was warm-hearted, who was always willing to__41__ human beings. One time, he ascended to heaven, lighted his torch at the chariot of the sun, and brought down fire. When gods and men were in dispute, Zeus availed himself of this dispute as an excuse for punishing mankind, deprived the race of _42___ but Prometheus regained the treasure, stealing it from heaven in a hollow tube.By Zeus’ order, Prometheus was chained to a rock on Mount Caucasus, and subjected to the attack of an eagle which, for ages, __43___ upon his liver, yet succeeded not in consuming it. In his steadfastness to withstand the ____44__ the Titan was supported by the knowledge that in the thirteenth generation there should arrive a hero, sprung from Zeus himself, to release him. And in fullness of time the hero did arrive: ___45___ other than the mighty Hercules. He killed the eagle and set Prometheus free.Zeus made the first woman and sent her to Prometheus and his brother, to punish them for their caring so much for men. She was made in heaven, every god contributing something to perfect her. Venus gave her beauty, Mercury persuasion, Apollo music, etc. all gods gave her gifts, silvery raiment and a broidered veil, a wonder to behold, and bright garlands of blooming flowers and a crown of gold. Because of what they gave her they called her Pandora, which means “the __46__ of all”.The gods __47__ her with a box into which each had put something harmful, and forbade her ever to _48__ it. Then they sent her to Epimetheus, who took her gladly although Prometheus had warned him never to accept anything from Zeus. He took her, and afterward he understood how good his brother’s __49__ had been. For Pandora, like all women, was possessed of a lively curiosity. She had to know what was in the box. One day she lifted the lid---and out flew plagues innumerable, sorrow and mischief for mankind. In terror Pandora clapped the lid down, but too_50____. One good thing, however, was there---Hope.

Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C), D). You should decide on the best choice. Passage oneQuestions 51 to 55 are based on the following passage.Some pessimistic experts feel that the automobile is bound to fall into disuse. They see a day in the not-too-distant future when all autos will be abandoned and allowed to rust. Other authorities, however, think the auto is here to stay. They hold that the car will remain a leading means of urban travel in the foreseeable future.The motorcar will undoubtedly change significantly over the next 30 years. It should become smaller, safer, and more economical, and should not be powered by the gasoline engine. The car of the future should be far more pollution-free than present types.Regardless of its power source, the auto in the future will still be the main problem in urban traffic congestion. One proposed solution to this problem is the automated highway system.When the auto enters the highway system, a retractable arm will drop from the auto and make contact with a rail, which is similar to those powering subway trains electrically. Once attached to the rail, the car will become electrically powered from the system, and control of the vehicle will pass to a central computer. The computer will then monitor all of the car’s movements.The driver will use a telephone to dial instructions about his destination into the system. The computer will calculate the best route, and reverse space for the car all the way to the correct exit from the highway. The driver will then be free to relax and wait for the buzzer that will warn him of his coming exit. It is estimated that an automated highway will be able to handle 10,000 vehicles per hour, compared with the 1,500 to 2,000 vehicles that can be carried by a present-day highway.51. One significant improvement in the future car will probably be__________.A) its power source B) its driving systemC) its monitoring system D) its seating capacity52. What is the author’s main concern?A) How to render automobiles pollution-free.B) How to make smaller and safer automobiles.C) How to solve the problem of traffic jams.D) How to develop an automated subway system.53. What provides autos with electric power in an automated highway system?A) A rail. B) An engine.C)A retractable arm. D) A computer controller.54. In an automated highway system, all the driver needs to do is________.A) keep in the right laneB) wait to arrive at his destinationC) keep in constant touch with the computer centerD) inform the system of his destination by phone55. What is the author’s attitude toward the future of autos?A) Enthusiastic B) Pessimistic C) Optimistic D) CautiousPassage twoQuestions 56 to 60 are based on the following passage.For an increasing number of students at American universities, Old is suddenly in. The reason is obvious: The graying of America means jobs. Coupled with the aging of the baby boom generation, a longer life span means that the nation’s elderly population is bound to expand significantly over the next 50 years. By 2050, 25 percent of all Americans will be older than 65, up from 14 percent in 1995. The change poses profound questions for government and society, of course. But it also creates career opportunities in medicine and health professions and in law and business as well. “In addition to the doctors, we’re going to need more sociologists, biologists, urban planners and specialized lawyers,”says Professor Edward Schneider of the University of Southern California’s (USC) School of Gerontology.Lawyers can specialize in “elder law”, which covers everything from trusts and estates to nursing-home abuse and age discrimination. Businessmen see huge opportunities in the elder market because the baby boomers, 74 million strong, are likely to be the wealthiest group of retirees in human history. “ Any student who combines an expert knowledge in gerontology with, say, an MBA or law degree will have a license to print money,”one professor says.Mona Armstrong is a 22-year-old senior at USC. She began college as journalism major but found she was “really bored with news”. So she took a class in gerontology and discovered that she liked it. She says, “I did volunteer work in retirement homes and it was very satisfying.”56. The graying of America brings about job opportunities for _______________.A) doctors and nursesB) sociologists and biologistsC) urban planners and specialized lawyersD) all of the above57. According to the passage, which of the following is NOT mentioned?A) There are 74,000,000 baby boomers in America.B) Baby boomers in America are usually in possession of a large fortune.C) One fourth of American population will be older than 65 in the middle of the 21st century.D) Most college students are interested in gerontology rather than other majors.58. Why can businessmen make money in the emerging elder market?A) Retirees are more generous in spending money.B) They can employ more gerontologists.C) The elderly possess an enormous purchasing power.D) There are more elderly people working than before.59. Who can make big money in the new century according to the passage?A) Retirees who are business-minded.B) The volunteer workers in retirement homes.C) College graduates with an MBA or law degree.D) Professionals with a good knowledge of gerontology.60. It can be seen from the passage that the expansion of America’s elderly population_________.A) will provide good job opportunities in many areasB) will impose an unbearable burden on societyC) may lead to nursing-home abuse and age discriminationD) will create new fields of study in universitiesPart Ⅳ VocabularyDirections: Choose the ONE that best completes each sentence from the four choices marked A),B),C) and D).61.
