3、e information given in the passage;N (for NO)if statement contradicts the information given in the passage;NG (for NOT GIVEN)if the information is not given in the passage.For question 8-10, complete the sentences with the information given in the passage.HighwaysEarly in the 20th century, most of t
4、he 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.With the increase in auto production, private turnpike (收费公路) companies under local authori
5、ties 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 tha
6、t, 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 the U.S. armys first transcontinental motor
7、convoy (车队), he noted: “The old convoy had started me thinking about good, two-lane highways, but Germanys Autobahn or motorway 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
8、War II, a tremendous increase in trucks and new roads were required. The war demonstrated how critical highways were to the defense effort. Thirteen per cent of defense plants received all their supplies by truck, and almost all other plants shipped more than half of their products by vehicle. The w
9、ar also revealed that local control of highways had led to a 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 nati
10、onal 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.The interstate highway system was finally launched in 1956 and has been hailed as one of the greatest public works projects of the century.
11、 To build its 44,000-mile web of highways, bridge, 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, th
12、e 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
13、 across the country, forever altering the face of America.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 engi
14、neered 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).By opening the North American continent, highways have enabled consumer goods and servic
15、es to reach people in remote and rural areas of the country, spurred the growth of suburbs, and provided people with greater options in term of jobs, access to cultural programs, health care, and other benefits. Above all, the interstate system provides individuals with what they cherish most: perso
16、nal freedom of mobility.The interstate system has been an essential element of the nations economic growth in terms of shipping and job creation: more than 75 percent of the nations freight deliveries arrive 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 s
