For thousands of years, man has enjoyed the taste of apples. Apples, which are about 85 percent of water, grow almost everywhere in the world but the hottest and coldest areas. Among the leading countries in apple production are China, France and the United States.
There’re various kinds of apples, but a very few make up the majority of those grown for sale. The three most common kinds grown in the United States are Delicious, Golden Delicious, and McIntosh.
Apples are different in color, size, and taste. The color of the skin maybe red, green, or yellow. They have various sizes, with Delicious apples being among the largest. The taste may be sweet or tart (酸). Generally, sweet apples are eaten fresh while tart apples are used to make applesauce (苹果酱).
Apple trees may grow as tall as twelve metres. They do best in areas that have very cold winters. Although no fruit is yielded during the winter, the cold period is good for the tree.

| Thousands of years ago man used handy
rocks for his surgical operations. Later he used sharp bone or horn, metal
knives and, more recently, rubber and plastic. And that was where we stuck, in
surgical instrument terms, for many years. In the 1960s a new tool was
developed, one which was, first of all, to be of great practical use to the
armed forces and industry, but which was also, in time, to revolutionize the art
and science of surgery. The tool is the laser and it is, being used by more and more surgeons all over the world, for a very large number of different complaints. The word laser means: Light Amplification by Stimulated Emission of Radiation. As we all know, light is hot; any source of light--from the sun itself down to a humble match burning--will give warmth.
