问题    Of all the foods we know, fruit is one of the most healthful. It is also one of the most tasty foods. Almost everyone enjoys fruit. Fruit is grown in almost every part of the world. There are hundreds of different kinds of fruits. And there are thousands of different varieties. In the United States alone, there are several hundred types of apples.
   In general, though, there are three separate groups. There are tropical fruits. These are most important. In this group, we have bananas and pineapples. They are shipped from tropical countries and are eaten all over the world.
   Next come the subtropical fruits. The most important of these are the citrus fruits. Oranges, tangerines, limes, and grapefruit are favorites. Other fruits in this class are figs, dates, and olives.
   The last group comes from the temperate zone. In this group are pears, apples, grapes, and plums. Many kinds of berries fit this group, too.
   Fruits are very important to the human diet.  Besides being tasty, they provide important acids, salts, and vitamins. Also, they are easy to digest. Nutrition experts say that the more fruit people eat, the healthier they become.
   Down through the centuries fruit has played a part in tales and history. In a Greek myth, Hercules sent Atlas to pick "golden apples" to pay for a crime. Today we believe these golden apples were oranges. During the 1700’s, British ships began to carry limes. It was found that sailors who drank the lime juice did not get sick. Since that time, British sailors have been called "limeys."
   The peach also has an exciting history. It has been a world traveler. Its journey began many, many centuries ago. Peaches were first grown in China. From China, traders of long ago carried peach trees to Persia. From there, Alexander the Great brought the fruit to Europe. From Europe, Spanish ships carried peaches to the New World.
   Through the years, fruit trees and plants have been improved. Today’s fruits are bigger. They also taste better. Different kinds of fruits are often being bred. We now have fruit that can travel to all parts of the world and still stay fresh. Even after traveling for some time, these new fruits keep the vitamins and minerals that are so good for our diet. Fruit will always be prized as a basic food that now can be enjoyed the whole year round.
