You should write no less than 120 words, and your composition should be based on the following information: 近年来,沙尘暴一直困扰着人们的生活。尽管人们已经认识到这一可怕的现象,但似乎也没有什么特别有效
2、的办法来防止它。作为一个公民,你认为哪些是防止沙尘暴的必要方法 ?阐明原因。 二、 Part II Reading Comprehension (Skimming and Scanning) (15 minutes) Directions: In this part, you will have 15 minutes to go over the passage quickly and answer the questions attached to the passage.

4、edar wood blocks. Built for the horse, carriage and foot traffic, they were usually poorly cared for and too narrow to accommodate automobiles. 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
5、 paved roads. Many were built using certifications 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 restriction
6、s, or commercial signs. During World War I, roads thorough the country nearly destroyed by the weight of trucks. When General Eisenhower returned from Germany in 1919, after serving in the U.S. Armys first transcontinental motor convey, he noted “the old convoy had started me thinking about good, tw
7、oline highway, but Germanys autobahn motorways had made me see the wisdom of broader ribbons across the land.“ It would take another war before the federal government would act on a national highway system. During World War II, a tremendous increase in truck and new roads required. The war demonstra
8、ted 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 highways had led to a confusing variety of design s
9、tandards. Even federal and state highways did not follow basic standards. Some states allowed trucks up to 36.000 pounds, while other restricted anything over 7000 pounds. A government study recommended a national highway system of 33,920 miles, and congress passed FederalAid Highway Act of 1944, wh
10、ich called for strict, centrally controlled design criteria. The interstate highway system was finally launched in 1956 and has been hailed as one of the greatest public works projects of century. To build its 44000mile web of highways, bridges and tunnel, hundreds of unique engineering designs and
11、solutions had to be work out. Consider the many geographic features of the country: mountains, steep grades, wetlands, rivers, deserts and plants. Variables included the slope of the land, the ability of the pavement to support the load, the intensity of the road use, and the nature of the underlyin
12、g soil. Urban areas were another problem. Innovative designs of roadways, bridges, overpasses and interchanges that could run through and bypass urban areas soon began to weave their way across the country, forever altering the face of America. Longspan, segmentconcrete, cabstayed bridges such as Ha
13、le boggs in Louisian and the Sunshine Skyway in Florida, and remarkable tunnels like fort McHenry in Maryland and Mr. Baker in Washington, met many of the nations challenges. Traffic control systems and methods of construction developed under the interstate program soon influenced highway constructi
14、on around the world, and were invaluable in improving the condition of urban and streets and traffic patterns. Today, the interstate system links every major city in the U.S., with Canada and Mexico. Build with the safety in mind, the highways have wide lines and shoulders dividing and median or bar
15、rier, long entry and exit lanes, curves engineered for safe turns, and limited success. The death rate on highways is half of all other U.S. road (0.86 deaths per 100 million passengers miles compare to 1.99 death per 100 million on all other roads). By opening the North American continent, highways
16、 have enable consumer goods services to reach people in remote and rural area of the country, spurred the suburbs, and provided people with greater options in terra of jobs, access to cultural programs, health care, and other benefits. Above all, the interstate system provides individuals with what
17、cherish most: personal freedom mobility.

18、or 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 spinoff industries like service stations, motels, restaurants, and shopping centers. It has allowed the relocation of manufacturing plant
19、s and other industries from urban areas to rural. By the end of the century there was an immense network of paved road, 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. T
20、he year construction began he said: “Together, the united forces of our communication and transportation systems are dynamic elements in the very name we bearUnited states. Without them, we would be a mere alliance of many separate parts.“ 2 National standards for paved roads were in placed by 1921.
