Centuries ago, man discovered that removing moisture(潮湿)from food helps to store it, and that the easiest way to do this is to expose the food to sun and wind. In this way the North American Indians produce pemmican(dried meat ground into powder and made into cakes), the Scandinavians make stockfish and the Arabs dried dates.
All foods include water—cabbage and other leaf vegetables contains as much as 93% water, potatoes and other root vegetables 80%, lean meat 75% and fish, anything from 80% to 60%, depending on how fatty it is. If this water is removed, the activity of the bacteria(细菌)which cause food to go bad is checked.
Fruit is sun-dried in Asia Minor, Greece, Spain and other Mediterranean countries, and also in California, South Africa and Australia. Various methods are used, but in general, the fruit is spread out on trays in drying yards in the hot sun.
Nowadays most foods are dried mechanically. The method of such dehydration(脱水)is to put food in chambers through which hot air is blown at temperatures of about 110℃ at entry to about 43℃ at exit. This is the usual method for drying such things as vegetables, minced(切碎的)meat, and fish.
Dried foods take up less room and weigh less than the same food packed in cans or frozen, and they do not need to be stored in special conditions. For these reasons they are invaluable to the climbers, explorers and soldiers in battle, who have little storage space. They are also popular with housewives because it takes so little time to cook them. Usually it is just a case of replacing the dried-out moisture with boiling water.According to the text, the open-air method of drying food .

Friends play a very important part in everyone’s life. Friendship usually develops during childhood. New friends are made when you progress through school. Those friends that you make as a student can usually last long. Friends influence your development, maturity (成熟) and sense of responsibility. A familiar expression is “you can tell a lot about a person by knowing who his friends are.” Friendship is based on common interests. If you like sports, most of your friends are likely to be athletic. If you enjoy reading and shopping, most of your friends do the same.
Some people call you their friends for the wrong reason. These people are not really friends. They are only “friends” on the outside, not the inside where it counts. They only want to be your friends if it is to their advantage. True friends are there whether you are rich or poor. It is easy to have many so-called “friends” if you are rich. By this time you should be able to separate your friends into the real or the “false”.
True friends are most special. They are also difficult to find. You can consider yourself very lucky if you have one true friend. This friend is eager to help you whenever necessary. He or she knows you would do the same for them. A true friend is someone you can talk to about any subject or problem. You and your true friend have good understanding of each other. True friends support you, take your side, and build up your confidence.. “So-called” friends refer to .
