【答案解析】[听力原文] 29-31
Do you like oranges and bananas? Oranges grow in Florida and California, while bananas grow in Central and South America. Trucks, trains, and ships bring this fruit to you. You can buy oranges and bananas in any market.
It was not always this way. Long ago, to get this fruit, you had to live where it grew as there were no cars then and ships were very slow. So good roads had to be built and cars had to be made. Now people can move about more quickly driving their cars and fast ships can bring fruit to us from far away. When it gets here, the fruit is put on fast trains or trucks. Then it is sent all over the country.
Airplanes also bring us things from faraway places. Right now it costs a lot of money to send things by air. But someday, airplanes may bring us all our fresh fruit, and someday even rockets may bring us fresh fruit still faster.
