Passage Two

　　Before the 20th century,the horse provided day to day transportation in the United State.

　　Trains were used only for long-distance transportation.

　　Today the car is the most popular sort of transportation in all of the United State.

　　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 car.

　　The average price of a recently made car was $2,050 in 1950,

　　$2,740 in 1960 and up to $ 4,750 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 car.

　　For this reason purchasing a new car takes a smaller part of a family's total earnings today.
