【正确答案】 A

【答案解析】[解析] 33-35 The United States is full of automobiles. There are still many families without cars, but some families have two or even more. However, cars are used for more than pleasure. They are a necessary part of life. Cars are used for business. They are driven to offices and factories by workers who have no other way to get to their jobs. When salesmen are sent to different parts of the city, they have to drive in order to carry their products. (33) {{U}}Farmers have to drive into the city in order to get supplies{{/U}}. Sometimes small children must be driven to school. In some cities school buses are used only when children live more than a mile from the school. (34) {{U}}When the children are too young to walk that far, their mothers take turns driving them to school{{/U}}. One mother drives on Mondays, taking her own children and neighbors' children as well. Another drives on Tuesdays, another on Wednesdays, and so on. This is called forming a car pool. Men also form car pools, with three or four men taking turns driving to the place where they all work. (35) {{U}}More car pools should be formed in order to put fewer automobiles on the road and to use less gasoline{{/U}}. Parking is a great problem, and so is the traffic in and around cities.
