The first postal service in North America began in New England in the 17th Century. All mail arriving in Massachusetts colony was sent to the home of an appointed official in Boston. In turn, he would deliver the mail from Boston on horseback to its destination, receiving one penny for each good article of mail. Later in the century postal services were established between Philadephia and Delaware. In 1691, the British crown appointed the first postmaster general to have charge of the mail for all the colonies in North America. Later, Benjamin Franklin served as the postmaster by the newly formed United States government.Franklin was responsible for establishing the Unite States postal system on a permanent basis. He increased the number of post offices, introduced the use of stagecoaches to carry mail, and started a package service system. Later in the 19th century, as railroad and steam boats appeared, they were used to carry mail into the towns.Some communities, especially those out west, were far from the services of transportation. To serve them, the post offices developed a system called “star routes”. Private contractors were paid to deliver mail to the communities from horse and wagon.The postal service, which started over three centuries ago, had developed into an extensive government service with post offices in every city, town, and villages in the United States.86.What is the subject of the passage?A. The U.S. postal system. B. The history of the U. S mailC. A history of Benjamin Franklin. D. Letter writing 87. When was the first North American postal service started? A. Two centuries ago B. Over 300 years agoC. In 1691 D. In the 16th century 88. For what did Benjamin Franklin deserve credit? A. He was the first postmaster general in North America. B. He established a government postal service for Britain. C. He served both British and American government. D. He governs the postal system in the U.S 89.Why were “star routes” started? A. Because the horse and wagon were slow in carrying mails. B. Because the trains were too fast. C. Because transportation was difficult for some towns. D. Because the communities didn’t like ordinary post offices. 90. What eventually happened to the postal service?A. It failed to serve the people in remote places.B. It developed a transport systemC.

Under proper conditions, sound waves will be reflected from a hillside or other such obstruction. Sound travels at the rate of about one-fifth of a mile per second. If the hill is eleven hundred feet away, it takes two seconds for the sound to travel to the hill and back. Thus, by timing the interval between a sound and its reflection(the echo), you van estimate the distance to an obstruction.During World War II the British used a practical application of this principle to detect German planes on their way to bomb London long before the enemy was near the target. They used radio waves instead of sound waves, since radio waves can penetrate fog and clouds. The outnumbered Royal Air Force (RAF) always seemed to the puzzled Germans to be lying in wait at the right time and never to be surprised. It was radio echoes more than anything else that won the Battle of Britain.Since the radio weaves were used to tell the direction in which to send the RAF planes and the distance to send them (their range of flight, in other words), the device was called radio detecting and ranging, and from the initials the word radar was coined.81. Sound waves reflected from a hill can be used to estimate the_______.A. intensity of sound B. distance to the hillC. speed of sound D. height of the hill82. Which of the following can be resulted from by practical application of this principle?A. a radio directing and ranging device. B. an electronic detecting device C. new electronic instruments for planes D. new radio sets for RAF bombers83. Radar enabled the English to_____ A. confuse German bomber pilots B. direct the outnumbered RAF planes effectivelyC. detect German planes on their way to London. D. both A and B84. Why did the British use radio waves?A. Because they were more exact than sound waves.B. Because they could not be detected.C. Because they were easier to use than sound waves.D. Because they could penetrate fog and clouds.85. What can you infer from the passage?A. Radar was a practical application of a well-known principle.B. Light waves could be used in a device similar to radar.C. Radar greatly increased the effectiveness of the REAF.D. Sound waves are reflected from a hillside under all conditions.

The Norwegian Government is doing its best to keep the oil industry under control. A new law limits exploration to an area south of the southern end of the long coastline; production limits have been laid down (though these have already been raised); and oil companies have not been allowed to employ more than a limited number of foreign workers. But the oil industry has a way of getting over such problems, and few people believe that the Government will be able to hold things back for long. As one Norwegian politician said last week: “We will soon be changed beyond all recognition.”Ever since the war, the Government has been carrying out a program of development in the area north of the Arctic Circle. During the past few years this program has had a great deal of success: Tromso has been built up into a local capital with a university, a large hospital and healthy industry. But the oil industry has already started to draw people south, and within a few years the whole northern policy could be in ruins.The effects of the oil industry would not be limited to the north, however. With nearly 100 percent employment, everyone can see a situation developing in which the service industries and the tourist industry will lose more of their workers to the oil industry. Some smaller industries might even disappear altogether when it becomes cheaper to buy goods from abroad.The real argument over oil is its threat to the Norwegian way of life. Farmers and fishermen do not make up most of the population, but they are an important part of it because Norwegians see in them many of the qualities that they regard with pride as essentially Norwegian. And it is the farmers and the fishermen who are most critical of the oil industry because of the damage that it might cause to the countryside and to the sea.76. The Norwegian Government would prefer the oil industry to ________________A. provide more jobs for foreign workersB. slow down the rate of its developmentC. sell the oil it is producing abroadD. develop more quickly than at present77. The Norwegian Government has tried to______A. encourage the oil companies to discover new oil sourcesB. prevent oil companies employing people from northern NorwayC. help the oil companies solve many of their problemD. keep the oil industry to something near its present size.78.According to the passage, the oil industry might lead in northern Norway to___________.A. the development of industryB. a growth in populationC. the failure of the development programD. the development of new towns79. In the south, one effect of the development of the oil industry might be____A. a large reduction in unemploymentB. a growth in the tourist industryC. a reduction in the number of existing industriesD. the development of a number of service industries80. Norwegian farmers and fishermen have an important influence because _______.A. they form such a large part of Norwegian societyB. their lives and values represent the Norwegian idealC. their work is so useful to the rest of Norwegian societyD. they regard oil as a threat to the Norwegian way of life

People on the MoveThe history of the American people is, in part, the history of the movement of the American people. They moved from the colonies of the East Coast to the open spaces of the West. They moved from the country and the farm to the city. More recently, Americans have been moving from the cities to the suburbs. Open Space: The Move WestPioneer Americans began moving from the East Coast to the West 250 years ago. They moved west for many reasons. One reason was the availability of unlimited open space and land for farming. Americans liked large open spaces, and they also liked the freedom and independence to develop the land in their own way. Some of the land became farms. Important minerals were discovered in some areas, so some of the land became mines. Other large areas became cattle ranches. There seemed to be enough land for everybody. But it was a difficult life---- a life of endless work and hardship.The CitiesAfter 1860, the Industrial Revolution changed the United States. Americans learned how to manufacture steel. They began to produce petroleum. The automobile was invented. Factories of all kinds began to appear, and cities began to grow up around the factories. Farmers and other country people moved to the growing cities in order to find jobs and an easier life. In the early 1900s, the cities were busy, exciting places. However, there was also a lot of poverty and hardship.The cities grew up----the buildings got taller--- and the cities grew out----they spread out from the center. Private houses with yards and porches disappeared. Apartment buildings, each one taller than the next, took their place. More and more people moved to the cities, and the cities got bigger and bigger.Some cities could not spread out because there was no room to do so. These cities, of which New York is the best example, became more and more crowded. More people meant more cars, trucks, and buses, more noise, more pollution, and more crime. Many cities became ugly and dirty. Some people and some businesses began to leave the cities and more to the suburbs outside the cities. The SuburbsThe move to the suburbs is still happening. Americans are looking for a small piece of land that they can call their own. They want a house with a yard. However, they do not want to give up the good jobs they have in the city. In many cases, companies in the suburbs give them jobs. In other cases, Americans tend to commute to and from the cities where their jobs are. In recent years, more and more businesses are moving to the suburbs. They are attracting many people and the suburbs are becoming crowded. What Next? Americans have watched their big cities fall slowly into disrepair and die. Many middle-class people have left the cities, and only the very rich and the very poor are staying behind.Concerned Americans are trying to solve the problems of noise, dirt, crime, and pollution in the big cities. They are trying to rebuild bad sections of the cities in order to attract and keep business people. They are trying to make their cities beautiful. Now many Americans are thinking of moving back to the cities.Other Americans are finding that even the suburbs have become too crowded. They are looking for unpolluted open spaces and for an independent way of life. They are ready to move from the suburbs to the country.Perhaps Americans will always be on the move.71. We learn from the passage that Americans first_____________. A. moved from the East to the West, then the country people moved to the city and later city people moved to the suburbs. B. moved from the East to the West, then the country people moved to the city and later people in the West moved back to the East. C. moved from the crowded cities in the East to the open spaces in the West, and later people in the West moved back to the East. D. flocked to the city and later the city people moved to the suburbs or to the open spaces in the West.72. According to the passage, Americans moved to the West because_____________. A. moving west represented and adventurous spirit that Americans cherish. B. life there was tougher but more attractive. C. there was more land available in the West.D. gold mines were discovered in the West.73. Private houses with yards and porches in the city____ A. disappeared because living in the city was no longer convenient fort their owners. B. took up too much space and had to make way for high-rising buildings. C. were left empty because their owners wanted to avoid the crimes in the city. D. were torn down because they became too ugly and dirty for their owners to live in74.Nowadays, in the suburbs of American cities,______________.A. crime is on the increase B. people find it hard to get a job. C. there is an increase of people and businesses. D. a new commuting system has been put into use.75. Many Americans nowadays__.A. are thinking of moving back to the city.

Oceanography has been defined as ‘The application of all sciences to the study of the sea.’ Before the nineteenth century, scientists with an interest in the sea were few and far between. Certainly Newton considered some theoretical aspects of it in his writings. But he was reluctant to go to sea to further his work. For most people the sea was remote, and with the exception of early intercontinental travelers or others who earned a living from the sea, there was little reason to ask many questions about it, let alone to ask what lay beneath the surface. The first time that the question ‘What is at the bottom of the oceans?’ had to be answered with any commercial consequence was when the laying of a telegraph cable from Europe to America was proposed. The engineers had to know the depth profile of the route to estimate the length of cable that had to be manufactured.It was to Maury of the US Navy that the Atlantic Telegraph Company turned, in 1853,for information on this matter. In the 1840s, Maury had been responsible for encouraging voyages during which soundings were taken to investigate the depths of the North Atlantic and Pacific Oceans. Later, some of his findings aroused much popular interest in his book The Physical Geography of the Sea. The cable was laid, but not until 1866 was the connection made permanent and reliable. At the early attempts, the cable failed and when it was taken out for repairs it was found to be covered in living growths, a fact which defied contemporary scientific opinion that there was no life in the deeper parts of the sea. Within a few years oceanography was under way. In 1872 Thomson led a scientific expedition, which lasted for four years and brought home thousands of samples from the sea. Their classification and analysis occupied scientists for years and led to a five-volume report, the last volume being published in 1895.66. The proposal to lay a telegraph cable from Europe to America made oceanographic studies take on_____.A.an academic aspect B. a military aspect C. a business aspect D. an international aspect67. It was _____ that asked Maury for help in oceanographic studies.A. the American Navy B. some early intercontinental travelersC. those who earned a living from the sea D. the company which proposed to lay an undersea cable68. The aim of the voyages Maury was responsible for in the 1840s was _____. A. to make some sounding experiments in the oceans B. to collect samples of sea plants and animals C. to estimate the length of cable that was needed D. to measure the depths of the two oceans69. ‘ Defied ’ in the 5th paragraph probably means ___ .A. ‘doubted ’ B. ‘ gave proof to’C. ‘ challenged ’ D. ‘ agreed to’70. This passage is mainly about ___A. the beginnings of oceanographyB. the laying of the first undersea cableC. the investigation of ocean depths D. the early intercontinental communications
