听力原文： Before the 20th century, the horse provided day to day transportation in the United States. Trains were used only for long-distance transportation.
Today the car is the most popular sort of transportation in all of the United States. It has completely replaced the horse as a means of everyday transportation. Americans use their car for nearly 90 percent of all personal trips.
Most Americans are able to buy cars. The average price of a recently made car was $ 2050 in 1950, $ 2740 in 1960 and up to $ 4750 in 1975. During this period American car manufacturers set about improving their products and work efficiency. As a result, the yearly income of the average family increased from 1950 to 1975 faster than the price of cars. For this reason purchasing a new car takes a smaller part of a family's total earnings today.
What was the only use of trains before the 20th century？
A．The use for short-distance transportation.
B．The use for day to day transportation.
C．The use for long-distance transportation.
D．The use for transportation of precious things.

The physical distribution of products has two primary aspects: transportation and storage.Both aspects are highly developed and specialized phases of marketing.The costs of both trans-porting and storing are built into the prices of products.Transportation can be by truck, rail-way, ship, or barge.For some items, such as exotic plants and flowers, or when rapid delivery is essential, air freight may be used.
Storage, or warehousing, is a necessary function because production and consumption of goods rarely match: items generally are not sold as quickly as they are made.Inventories build up,both in warehouses and at retail establishments, before the foods are sold.The transporta-tion function is involved in bringing goods to a warehouse and taking them from it to retail stores.
Storage performs the service of stabilizing market price.If, for example, no agricultural product could be stored, all food would have to be put on the market immediately.This would, of course, create a glut and lower prices drastically.There would be an immediate benefit to consumers, but in the long run they would suffer.Farmers, because of low prices, would be forced off the land, and the amount of food produced would decrease.This, in turn, would raise consumer prices.
Warehouses for storage are of several types.Private warehouses are owned by manufactur-ers.Public warehouses, in spite of their name, are privately owned facilities, but they are in-dependent of manufacturer ownership.General-merchandise warehouses store a great variety of products.Cold-storage warehouses store perishable goods, especially food products.Grain ele-vators are a kind of warehouse used to keep wheat and other grains from spoiling.A bonded warehouse is one that stores foods, frequently imported, on which taxes must be paid before theyare sold.Cigarettes and alcoholic beverages are common examples.
The distribution center is a more recently developed kind of warehouse.Many large com- panics have several manufacturing plants, sometimes located outside the country.Each plant doesnot make every company product but specializes in one or more of them.The distribution center allows a manufacturer to bring together all product lines in one place.Its purpose is to minimize storage and to ease the flow of goods from manufacturers to retailers rather than build up extensive inventories.It reduces costs by speeding up product turnover.Very large corporations will have several distribution centers regionally or internationally based
