Have you ever noticed how busy our roads are becoming? Every year more and more cars are using them. Already in such countries as America, almost every family has a car. Many accidents happen because cars are now made to travel very fast. Also, people waste time and money every day as long lines of cars move slowly into towns and cities. In most big towns it is very hard to find parking spaces.
Wide, smooth（平的）, straight（直的） roads must be built now in place of the old and narrow roads. These roads must not pass through towns and cities. They must not be crossed by other roads.
Today such roads are being built in many countries in the world. These roads have at least two lanes, one for slow-moving traffic and the other for fast-moving traffic.
These roads do not pass through towns and cities, horses and bikes are not allowed on them. Accidents do not usually happen. Cars can travel hundreds of miles without having to stop.
But these modern roads often cannot be built in towns and cities. Before a road in a town can be made wider, many buildings have to be pulled down.
Some people feel that more car-parks should be built outside a city, then the drivers should leave their cars and catch a bus or take a taxi to their offices.

(答案→)D 解析：本文叙述了为了解决现在道路的拥挤问题，新的道路将会建设，并阐述了新道路的一些特点。【小题1】细节理解题。根据文中Many accidents happen because cars are now made to travel very fast和in place of the old and narrow roads.以及下文的They must not be crossed by other roads.可知这些都是引起交通事故的原因。故选D。【小题2】细节理解题。根据文中These roads have at least two lanes, 这条路至少有两个车道。故选A。【小题3】判断推理解题。.根据第一段的描述可知，现在的道路很拥挤，每天都有大量的车子，从而造成拥挤和停车困难等问题。所以因为道路破旧，才必须修建新的道路。故选D。【小题4】细节理解题。根据But these modern roads often cannot be built in towns and cities. Before a road in a town can be made wider, many buildings have to be pulled down.可知应选D。【小题5】主旨大意题。这篇文章主要讲述了为了缓解现在旧道路的拥挤问题，新道路将会建设，并阐述了新道路的特点。故选B。
