听力原文： The use of illegal drugs by U.S. teenagers has increased in the past two years, according to the latest survey by University of Michigan researchers. The increase reverses a downward trend in drug use among teenagers that began in the late 1970s.

Results of a survey of 50,000 eighth, tenth and twelfth graders throughout the United States indicated a sharp rise in the use of drugs. The researchers also noted an increase in the percentage of students who smoke cigarettes, a drop in the percentage of students who drink alcohol, and no change in cocaine use, which remained at a low level.

Although the general rise in the use of drugs is disturbing, the numbers are still far below the recorded high level of drug use in the 1970s.

A consistent drop in drug use, such as the one that occurred be- fore the recent rise, can't be taken for granted, because each generation of American youth has almost no knowledge of drugs and has to learn the same hard lessons.

(26)

A．A slight drop in the use of cocaine.

B．A drop in the use of cigarettes.

C．A sharp rise in the use of drugs.

D．A rise in the use of alcohol.

amily paid $ 1, 311. That was a price increase of nearly one third. Every family has had this sort of experience. Everyone a-grees that the cost of feeding a family has risen sharply. But there is less agreement when reasons for the rise are being discussed. Who is really responsible？

Many blame the farmers who produce the vegetables, fruit, meat, eggs, and cheese mat are stored for sale. According to the U. S. Department of Agriculture, the farmer' s share of the $ 1, 311 spent by the family in 1972 was $ 521. This was thirty-one percent more than the farmer had received in 1959. But farmers claim that this increase was very small compared to the increase in their cost of living. Fanners tend to blame others for the sharp rise in food prices. They particularly blame those who process the farm products after the products leave the farm. These include truck drivers, meat packers, manufacturers of packages and other food containers, and the owners of stores where food is sold. They are among the " middlemen" who stand between the farmer and the people who buy and eat the food. Are middlemen the ones to blame for rising food prices？

Of the $ 1, 311 family food bill in 1972, middlemen received $ 790, which was thirty-three percent more than they had received in 1959. It appears that the middlemen' s profit has increased more than the farmer' s. But some e-conomists claim that the middlemen' s actual profit was very low. According to economists at the First National City Bank, the profit for meat packers and food stores amounted to less than one percent. During the same period all other manufacturers were making a profit of more than five percent. By comparison with other members of the economic system, both farmers and middlemen have profited surprisingly little from the rise in food prices.

Who then is actually responsible for the size of the bill a housewife must pay before she carries the food from the store？ The economists at First National City Bank have an answer to give housewives, but many people will not like it. These economists blame the housewife herself for the jump in food prices. They say that food costs more now because women don't want to spend much time in the kitchen. Women prefer to buy food which has already been prepared before it reaches the market.
