听力原文： A good way to see the USA is by car. Americans love their automobiles and in the past fifty years they have developed a vast network of roads and freeways to help them reach their destinations.

As few visitors have their own cars, renting one is the next best thing. You will need a valid driver's license and either international credit cards, or a deposit.

You should start out with a working knowledge of the road. Regulations vary from state to state and this can be very confusing to a newcomer. For example, in some states it is legal to turn right at a red light if there is no approaching traffic, while in other states you will be fined for this action. Throughout the country it is forbidden to pass a school bus when it has stopped to let off children.

The size of the country may startle you at first and you may be surprised at the spectacular physical beauty. When the first pioneers began to expand west into the wildness, the natural resources of the land seemed inexhaustible. Nearly 1,000 million acres of land was covered by virgin forest. Much of this was burnt off for farmland and it soon became apparent that the government would have to take action or the natural beauty of the land would be lost forever.
