(19) 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, (20) 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. (21) 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.
Questions 19 to 21 are based on the passage you have just heard.
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、Its construction started before World War I.
B、Its construction cost more than $40 billion.
C、It is efficiently used for transport.
D、It is one of the best in the world.
答案
D
解析
浏览四个选项,从选项中的construction,started,cost,used for,best等词可推测,此题与对某物的具体描述有关。题干问的是关于美国的高速公路系统,讲话者说了什么。短文开头提到,美国拥有一套世界上顶尖的高速公路系统,故答案为D。短文前半部分提到,一战后,军队为了国防事业,想要在美国建设一套高速公路系统。由此可知,A项(它于第一次世界大战之前开始动工)与短文意思相反,故排除。短文中间部分提到,国会拨款超过250亿美元用来建设公路,B项(它的建设耗资400多亿美元)与短文内容不符,故排除。C项(它被有效应用在交通运输上)短文未提及,故排除。
