The United States has one of the best highway systems in the world
. Interstate highways connect just about every large and mid-sized city in the country. Did you ever wonder why such a complete system of excellent roads exists? For an answer, you would have to go back to the early 1920s.
In those years, just after World War I , the military wanted to build an American highway system for national defense. Such a system could, if necessary, move troops quickly from one area to another. It could also get people out of cities in danger of being bombed.
So-called roads of national importance were designated, but they were mostly small country roads. In 1944, Congress passed a bill to upgrade the system, but did not fund the plan right away. In the 1950s, the plan began to become a reality. Over $25 billion was appropriated by Congress, and construction began on about 40,000 miles of new roads. The idea was to connect the new system to existing expressways and freeways. And though the system was built mostly to make car travel easier, defense was not forgotten. For instance, highway overpasses had to be high enough to allow trailers carrying military missiles to pass under them.
By 1974, this system was mostly completed
. A few additional roads would come later. Quick and easy travel between all parts of the country was now possible.
19. What does the speaker say about the American highway system?
20. What was the original purpose of building a highway system?
21. When was the interstate highway system mostly completed?
选项
A、To improve transportation in the countryside.
B、To move troops quickly from place to place.
C、To enable people to travel at a higher speed.
D、To speed up the transportation of goods.
答案
B
解析
事实细节题。短文提到,美国的公路建造可追溯到20世纪20年代初,在第一次世界大战后的那些年里,军方想要建立一个公路系统用于国防,这样的一个系统可以在必要时迅速将部队从一个地区转到另一个地区,也可以让人们离开有被轰炸的危险的城市。由此可知,美国建造公路的最初动机是部队的转移需求。
