听力原文:W: Is there such a thing as a typical shoplifter?
M: Uh, not really... But there are certain types most shoplifters fall into. Three types, I would say.
W: Tell me more about these three types.
M: Well... uh... people in the first type are what I call "the sudden impulse type". Doctors and psychologists call such people kleptomaniacs. They see something and just can't ... uh... help stealing it. The strange thing about this first type is that the people in it are often well off and could easily afford to buy the thing. Sometimes they don't even need it... and often they're emotionally disturbed in some way.., middle-aged women, for example, whose husbands have left them, or perhaps older men whose wives have recently died.
W: What about the second type?
M: Well, those are people who are really... "little thieves" They work alone, and know exactly what they want before they go into the store. These days a lot of them, but by no means all, are teenagers who steal things they can't afford. Leather jackets, watches, expensive cosmetics, things like that.
W: And the third type.'? What kind of people do you find in the third type?
M: Ah, yes, they're what I call "the experts".
W: Why?
M: Well, first of all, because they're highly organized. And secondly because they do it for a living. They usually operate in groups of three or sometimes four, and they're extremely difficult to catch.
W: Can they make a lot of money that way?
M: Oh, yes. They're very well off, believe me... much better off than a store detective..., or even a journalist!

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.
