Parents (12)_ that children did not show them proper respect and (13)_, while children complained that their parents did not understand them at all. What had gone wrong? Why had the generation gap suddenly appeared? (14)_, the generation gap has been around for a long time. Many (15)_argue that it is built into the fabric of our society.One important cause of the generation gap is the opportunity that young people have to choose their own life-styles. In more (16)_ societies, when children grow up, they are expected to live in the same area as their parents, to marry people that their parents know and (17)_ of, and often to continue the family occupation.

Part Reading Comprehension (35 minutes)Directions: There are 4 passages it this part. Each passage is followed by some questions or unfinished statements. 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. Passage OneQuestions 21 to 25 are based on the following passage: Chemistry did not emerge as a science until after the scientific revolution in the seventeenth century and then only rather slowly and laboriously. But chemical knowledge is as old as history, being almost entirely concerned with the practical arts of living. Cooking is essentially a chemical process; so is the melting of metals and the administration of drugs and potions. This basic chemical knowledge, which was applied in most cases as a rule of thumb, was nevertheless dependent on previous experiment. It also served to stimulate a fundamental curiosity about the processes themselves. New information was always being gained as artisans improved techniques to gain better results. The development of a scientific approach to chemistry was, however, hampered by several factors. The most serious problem was the vast range of material available and the consequent difficulty of organizing it into some system. In addition, there were social and intellectual difficulties, chemistry is nothing if not practical; those who practice it must use their hands, they must have a certain practical flair. Yet in many ancient civilizations, practical tasks were primarily the province of a slave population. The thinker or philosopher stood apart from this mundane world, where the practical arts appeared to lack any intellectual content or interest. The final problem for early chemical science was the element of secrecy. Experts in specific trades had developed their own techniques and guarded their knowledge to prevent others from stealing their livelihood. Another factor that contributed to secrecy was the esoteric nature of the knowledge of alchemists, who were trying to transform base metals into gold or were concerned with the hunt for the elixir that would bestow the blessing of eternal life. In one sense, the second of these was the more serious impediment because the records of the chemical processes that early alchemists had discovered were often written down in symbolic language intelligible to very few or in symbols that were purposely obscure. 21. What is the passage mainly about? A) The scientific revolution in the seventeenth century.B) Reasons that chemistry developed slowly as a science.C) The practical aspects of chemistry.D) Difficulties of organizing knowledge systematically. 22. According to the passage, how did knowledge about chemical processes increase before the seventeenth century? A) Philosophers devised theories about chemical properties. B) A special symbolic language was developed.C) Experience led workers to revise their techniques. D) Experts shared their discoveries with the public. 23. The bold word hampered in Line 1 Para 2 is closest in meaning to_. A) recognized B) determined C) solved D) hindered 24. The bold word it refers to which of the following? A) Problem. B) Material.C) Difficulty. D) System. 25. Which of the following statements best explains why the second of these was the more serious impediment(Underlined)?A) Chemical knowledge was limited to a small number of people.B) The symbolic language used was very imprecise.C) Very few new discoveries were made by alchemists. D) The records of the chemical processes were not based on experiments.Passage TwoQuestions 26 to 30 are based on the following passage:An important new industry, oil refining, grew after the Civil War. Crude oil, or petroleum a dark, thick ooze from the earth had been known for hundreds of years, but little use had everbeen made of it. In the 1850s Samuel M. Kier, a manufacturer in western Pennsylvania, begancollecting the oil from local scapages and refining it into kerosene. Refining, like smelting, is aprocess of removing impurities from a raw material. Kerosene was used to light lamps. It was a cheap substitute for whale oil, which was becoming harder to get. Soon there was a large demand for kerosene. People began to search fornew supplies of petroleum. The first oil well was drilled by E. L. Drake, are tired railroad conductor. In 1859 he begandrilling in Titusville, Pennsylvania. The whole venture seemed so impractical and foolish thatonlookers called it Drakes Folly. But when he had drilled down about 70 feet(21 meters),Drake struck oil. His well began to yield 20 barrels of crude oil a day. News of Drakes success brought oil prospectors to the scene. By the early 1860s thesewildcatters were drilling for black gold all over western Pennsylvania. The boom rivaled theCalifornia gold rush of 1848 in its excitement and Wild West atmosphere. And it brought farmore wealth to the prospectors than any gold rush. Crude oil could be refined into many products. For some years kerosene continued to be theprincipal one. It was sold in grocery stores and door-to-door. In the 1880s and 1890s refinerslearned how to make other petroleum products such as waxes and lubricating oils. Petroleumwas not then used to make gasoline or heatingoil.26.What is the best title for the passage?A) Oil Refining: A Historical PerspectiveB) The California Gold Rush: Get Rich QuicklyC) Private Property: Trespassers Will Be ProsecutedD) Kerosene Lamps: A Light in the Tunnel27.It can be inferred form the passage that kerosene was preferable to whale oil because whaleoil was too_.A) expensive B) thick C) hot D) polluted28.According to the passage, many people initially thought that E. L. Drake had made a mistakeby_.A) going on a whaling expedition B) moving to PennsylvaniaC) searching for oil D) retiring from his job29.Why does the author mention the California gold rush?A) To explain the need for an increased supply of goldB) To indicate the extent of United States mineral wealthC) To describe the mood when oil was first discoveredD) To argue that gold was more valuable than oil30. Which of the following words could best replace the word one (Underlined)?A) Oil. B) Door. C) Store. D) Product.Passage ThreeQuestions 31 to 35 are based on the following passage:Welcome to the U.S.A.! Major credit cards are accepted!By the millions they are coming no longer the tired, the poor, the wretched masses longing for a better living. These are the wealthy. We dont have a budget, says a biologist from Brazil, as she walks with two companions through New York Citys South Street. We just use our credit cards.The US has long been one of the worlds most popular tourist destinations, but this year has been exceptional. First, there was the World Cup, which drew thousands from every corner of the globe; then came the weakening of the US dollar against major currencies. Now the US, still the worlds superpower, can also claim to be the worlds bargain basement(廉价商品部). Nobody undersells America these days on just about everything, from consumer electronics to fashion clothes to tennis rackets. Bottom retail prices anywhere from 30 % to 70% lower than those in Europe and Asia have attracted some 47 million visitors, who are expected to leave behind $ 79 billion in 1994. Thats up from $74 billion the year before.True, not everyone comes just for bargains. There remains an undeniable fascination in the rest of the world with all things American, nourished by Hollywood films and US television series. But shopping the USA is proving irresistible. Every week thousands arrive with empty suitcases ready to be filled; some even rent an additional hotel room to hold their purchases. The buying binge（无节制）has become as important as watching Old Faithful Fountains erupt in Yellowstone Park or sunbathing on a beach in Florida.The US has come at last to appreciate what other countries learned long ago: the pouring in of foreign tourists may not always be convenient, but it does put money in the bank. And with a trade deficit at about $130 billion and growing for the past 12 months, the US needs all the deposits it can get. Compared with American tourists abroad, visitors to the US stay longer and spend more money at each stop; an average of 12.2 night and $ 1624 a traveler versus the Americans four nights and $298.31. From what the Brazilian biologist says, we know that tourists like her _.A) are reluctant to carry cash with themB) simply don t care how much they spendC) are not good at planning their expenditureD) often spend more money than they can afford32.The reason why 1994 was exceptional is that _.A) it saw an unusually large number of tourists to the USB) it witnessed a drop in the number of tourists to the USC) tourism was hardly
