问答题
每个美国家庭平均拥有1.8辆车，也就是说，这一人口26800万的国家有14700万辆车；平均每辆车每年以每小时50英里的速度开1万英里。大多数车都用于日常交通；乘公共交通工具上班的美国人还不到6%。现在一些非常好的高速公路上，每天的汽车流量是其设计流量的三倍甚至更多，而且每天两次，高速公路会变得宛如停车场。旧金山和华盛顿这两个城市荣膺最差城市交通奖。[听力原文]According to government statistics in 2001, the average American household has 1.8 vehicles, that is, 147 million vehicles in a country of 268 million people; each vehicle is driven an average of 10,000 miles per year at an average highway speed of 59 miles per hour. Most cars are used for daily commuting; less than 6% of the American workforce uses public transportation to get to work. Some of the country’s wonderful high-speed highways now carry three or more times the intended amount of traffic and twice a day turn into parking lots. San Francisco and Washington D. C win the prize for the two cities with the worst congestion.
