Women also worked in textile and garment factories. By the 1990s , the percent of employed women rose 28 , to about 20%. Occupations that were opening up to women at this time included secretary, telephone operator, and sales clerk.During the Great Depression in 1903s , money and jobs were 29 ,and many people became unemployed . Women had an especially hard time finding work. In the 1940s the United States was fighting World War II. As more and more men were 30 up to fight, many jobs opened up to women. For the first time in U.S. history, many women worked in 31 industry. By now , about 45% of women were employed.After the war, many people 32 women to give up their jobs .They felt that the jobs should go to the men returning from war . So, by the 1950s , there were fewer women working , and fewer jobs women. In the 1950s women were encouraged to stay at home and keep house.33 open to Beginning in the 1960s, the 34 of women working gradually rose. In the 1960s, 35% of women had jobs. In the 1970s, 44% had jobs. Women now worked as stockbrokers, doctors, and lawyers in addition to the more 35 jobs.Section BDirections: In this section, you are going to read a passage with ten statements attached to it. 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.Highways[A] Early in the 20th century, most of the streets and roads in the U.S. were made of dirt, brick, and cedar wood blocks. Built for horse, carriage, and foot traffic, they were usually poorly cared for and too narrow to accommodate (容纳) automobiles.[B] With the increase in auto production, private turnpike ( 收费公路) companies under local authorities began to spring up, and by 1921 there were 387,000 miles of paved roads. Many were built using specifications of 19th century Scottish engineers Thomas Telford and John MacAdam （for whom the macadam surface is named ）, whose specifications stressed the importance of adequate drainage. Beyond that, there were no national standards for size, weight restrictions, or commercial signs, During World War I, roads throughout the country were nearly destroyed by the weight of trucks. When General Eisenhower returned from Germany in 1919, after serving in theU.S. Army’s first transcontinental motor convoy ( 车队) ，he noted : “The old convoy had started me thinking about good, two-lane highways ,but Germany’s Autobahn or motorway had made me see the wisdo m of broader ribbons across the land.”[C]It would take another war before the federal government would act on a national highway system. During World War II, a tremendous increase in trucks and new roads were required. The war demonstrated how critical highways were to the defense effort. Thirteen percent of defense plants received all their supplies by truck, and almost all other plants shipped more than half of their products by vehicle. The war also revealed that local control of highways had led to confusing variety of design standards. Even federal and state highways did not follow basic standards. Some states allowed trucks up to 36,000 pounds, while others restricted anything over 7,000 pounds. A government study recommended a national highway system of 33,920 miles and Congress soon passed the Federal-Aid Highway Act of 1944, which called for strict, centrally controlled design criteria.[D]The interstate highway system was finally launched in 1956 and has been hailed as one of the greatest public works projects of the century. To build its 44,000-mile wed of highways, bridges and tunnels, hundreds of unique engineering designs and solutions had to be worked out. Consider the many geographic features of the country : mountains, steep grades, wetlands, rivers, deserts, and plains. Variables included the slope of the land, the ability of the pavement to support the load, the intensity of road use, and the nature of the underlying soil , Urban areas were another problem. Innovative designs of roadways, tunnels , bridges, overpasses, and interchanges that could run through or bypass urban areas soon began to weave their way across the country, forever altering the face of America.[E]Long-span, segmented-concrete, cable-stayed bridges such as Hale Boggs in Louisiana and the Sunshine Skyway in Florida, and remarkable tunnels like Fort McHenry in Maryland and Mt. Baker in Washington, met many of the nation’s physical challenges. Traffic control systems and methods of construction developed under the interstate program soon influenced highway construction around the world , and were invaluable in improving the condition of urban streets and traffic patterns.[F]Today, the interstate system links every major city in the U.S. and the U.S. with Canada and Mexico. Built with safety in mind, the highways have wide lanes and shoulders, dividing medians or barriers, long entry and exit lanes, curves engineered for safe turns, and limited access. The death rate on highways is half that of all other U.S. roads (0.86 deaths per 100 million passenger miles compared to 1.99 deaths per 100 million on all other roads ).[G]By opening the North American continent, highways have enabled consumer goods and services to reach people in remote and rural areas of the country, spurred the growth of suburbs, and provided people with greater options in terms of jobs, access to cultural programs, health care, and other benefits. Above all, the interstate system provides individuals with what they cherish most : personal freedom of mobility.[H]The interstate system has been an essential element of the nation’s economic growth in terms of shipping and job creation : more than 75 percent of the nation’s freight deliveries arriv e by truck ; and most products that arrive by rail or air use interstates for the last leg of the journey by vehicle. Not only has the highway system affected the American economy by providing shipping routes, it has led to the growth of spin-off industries like service stations, motels, restaurants and shopping enters. It has allowed the relocation of manufacturing plants and other industries from urban areas to rural.[I]By the en of the century there was an immense network of paved roads, residential streets, expressways, and freeways built to support millions of vehicles. The highway system was officially renamed for Eisenhower to honor his vision and leadership. The year construction began he said : “ Together , the united forces of our communication and transportation systems are dynamic elements in the very name we bear-United States, Without them, we would be a mere alliance of many separate parts.”36.Trucks using the interstate highways deliver more than half of the nation’s freight deliveries.37.It was in the 1950s that the American government finally took action to build a national highway s ystem.38.The interstate highway system provides access between major cities in America.39.National standards for paved roads were not in place by 1921.40.The greatest benefit brought about by the interstate system was personal freedom of mobility.41.Many of the problems presented by the country’s geographical features found solutions in innovativeengineering projects.42.The death rate on interstate highways is lower that that of other American roads.43.The interstate highway system promoted the development of service stations, motels and restaurants.44.The interstate system was renamed after Eisenhower in recognition of his vision and leadership.45.General Eisenhower felt that the broad German motorways made more sense than the two-lane highways ofAmerica.Section CDirections: There are 2 passages in this section. 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 Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.What should you think about in trying to find your career? You are probably better at some school subjects than others. These may show strengths that you can use in your work. A boy who is good at mathematics can use that in an engineering career. A girl who spells well and likes English may be good at office work. So it is important to know the subjects you do well in at school. On the other hand , you may not have any specially strong or weak subjects but your records show a general satisfactory standard . Although not all subjects can be used directly in a job, they may have indirect value. A knowledge of history is not required for most jobs but if history is one of your good subjects you will have learned to remember facts and details. This is an ability that can be useful in many jobs.Your school may have taught you skills, such as typing or technical drawing, which you can use in your work . You may be good at metal work or cookery and look for a job where you can improve these skills. If you have had a part-time job on Saturdays or in the summer, think about what you gained from it. If nothing else, you may have learned how to get to work on time, to follow instructions and to get on with older workers. You may have learned to give correct change in a shop, for example, Just as important, you may become interested in a particular industry or career you see from the inside in a pare-time job.Facing your weak points is also part of knowing yourself. You may be all thumbs when you handle tools, perhaps you are a poor speller or cannot add up to a column of figures. It is better to face any weaknesses than to pretend they do not exist. Your school record, for instance, may not be too good, yet it is an important part of your background . You should not be apologetic about it but instead recognize that you will have a chance of a fresh start at work.46.Which of the following can best sum up the first paragraph?A)The importance of doing well at school.B)Using school performance to help to choose a career.C)The importance of being good at all subjects.D)The indirect value of school work.47.The subject which is supposed to have no direct value for job hunting is .A. mathematics B) EnglishC)technical drawing D) history48.The writer thinks that for a student to have a part-time job is probably .A)a waste of time that could have been spent on studyB)useful for his future workC)a good way to earn extra moneyD)a good way to find out his weak points49.According to the passage, if a student’s school record is not good, he .A)will fail in his future workB)will not be able to find a suitable jibC)will regret not having worked harder at schoolD)may do well in his future work50.The whole passage centers on .A)choosing a career according to what one is good atB)acquiring knowledge by working hard at schoolC)finding one’s strong and weak pointsD)developing one’s abilities in school workPassage TwoQuestions 51 to 55 are based on the following passage.Levittown was the name given to three suburban developments constructed in the post World War II decades by Levitt and Sons, the most important private builder of this period .Using new mass production techniques they had learned while building housing for military personnel during the Second World War, they turned home building from a cottage industry into a major manufacturing process.During World War II, they received government contracts to build homes for war workers. Under deadline pressure, they developed mass production methods to build houses quickly . These techniques were carried over to their postwar suburban developments. On May 7, 1947, William Levitt announced his plans to build 2,000 houses in a former potato field in the state of New York. Then , by the time this Levittown was completed in 1951, it had contained 17,450 homes for 75,000 people in New York , Levitt eventually built two more Levittowns, in the states of Pennsylvania and New Jersey . Each contained the same curving streets, community pools, and neighborhood parks, playgrounds as the first development did.Some observers criticized the monotonous uniformity of the Levittowns, charging that they are just the symbol of materialism, but Levittowns were overwhelmingly welcomed by the public. They were cheap, comfortable , efficient, and ideal for young people just starting out in life. Thousands of middle class people, especially some young couples, couples, crowded in city apartments or still living with their parents, rushed to purchase them, Fourteen hundred contracts were signed in one day in 1949.Levittown symbolized the most significant social trend of the postwar era in the United States-the flight to the suburbs. The resulting massive shift in population from the central city to the suburbs was accompanied by a baby “boom” that started after soldiers returned home fr om World War II and got married .By 1960, one-third of the nation’s population lived in the suburbs. The nation underwent its greatest increase in population since 1910.51.What does the passage mainly discuss?A)Levittown was built by William Levitt with the mass-production method.B)Levittown served as an ideal and leading example of social changes in the U.S. after World War II.C)Increases in the population of the United States after the war.D)Why there was a housing shortage after World War II.52.What was the original reason for Levitt to use the method of mass production to build houses？A)In order to reduce the cost of the construction.B)To meet people’s need to own their own houses after the war.C)There was a population shift from central cities to the suburbs.D)He was forced to do so because of the lack of time.53.One of the reasons Levittowns were criticized by some observers was that .A)the land on which the first Levittown was built was previously used for agricultureB)the methods Levitt used for construction were new to themC)the Levittown houses were lack of varietyD)home building shouldn’t be changed from a cottage industry into a major manufacturing process54.Thousands of people rushed to buy Levitt’s houses because of .A)the low pricesB)the convenient transportationC)its location in the suburbsD)the crowded family in the city55.What can be inferred from the passage?A)Levitt’s houses have led to the great shift in population after the Second World War.B)W illiam Levitt had tapped the postwar desire of young Americans to raise their children outside the centralcity.C)L evittown has become the world’s most perfectly planned community.D)The population of the United States increased sharply after the Second World War.Part ⅣTranslation (30 minutes)Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese intoEnglish.
