世界史上最早的舞谱是哪一部？

"Extra? Extra！Gasoline hits four dollars a gallon!”

No one will really be shocked一except, perhaps, the old-timers who tell about the good old days when gas was three gallons for a dollar, and people drove around "just for the fun of it".

As a matter of fact; the price of gas has been rising fast and steadily for several years, and many adjustments have already been made.

There was, for a time, considerable unemployment in the auto industry, and three quarters of the garages and service stations have gone out of business. However; the bicycle and motor-scooter business has flourished（兴旺); and many people have found employment there: Now that Federal Motors has brought out its new Lilliput, which travels forty miles on a gallon, the auto business is picking up again. The factories that haven't switched over to two-wheel transportation are working on their new smaller models. There is talk, too, about bringing out new steam and electric automobiles that will be just as economical as the old cars.

In the meantime, streetcars are gradually replacing buses all over the country because of the greater economy of electric power. And many people who have seldom used public transportation are now riding the streetcars while their automobiles rust（生锈）in their garages. There's no market at all for their big, luxurious cars, for only the wealthy can now afford to operate them. Many people are now shopping in their own neighborhood, and small businesses are thriving.

Ministers, educators, and editorial writers are pointing out that there has been a great improvement in family life. Families now stay at home more for their fun, and children and parents are becoming better acquainted. The stores report a booming business in parlor games, hobby materials, books, musical instruments and albums.

People have lost their pale indoor look. The revival of the lost art of walking has brought a healthy pink back to many a cheek. This return to the heels has revolutionized the clothing styles; people now need to be ready for all kinds of weather:

These conditions, however, may not last. Already our clever chemists are at work on new synthetic fuels which, they say, will put us right back where we were一on wheels. Shall w e wish them success or not?

小题1:Which of the following is NOT a result of the gas price rising?

A．More people prefer to travel on public transportation which costs less than driving cars.

B．People return to the traditional exercise of walking, which helps them to look healthier.

C．People shop in nearby stores without having to drive, so small businesses are declining.

D．The auto industry has been forced to develop new models which are more economical.小题2:The purpose of writing this passage is＿．

A．to show the chain reaction of the rising gas price

B．to discuss whether it's necessary to work on new fuels

C．to warn people not to use too much gasoline

D．to picture what life will be like if gas runs out小题3:What is the best title for this passage?

A．New fuels on the way

B．Cars or bicycles, that is a question

C．End of the good old days

D．From wheels to heels
