     Centuries ago, man discovered that removing moisture from food helps to store it, and that the easiest way to do this is to expose the food to sun and wind.

    All foods including water — cabbage and other leaf vegetables contains as much as 93% water, potatoes and other root vegetables 80%, lean (瘦的) 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 which cause food to go bad is controlled.

    Nowadays most foods are dried mechanically. The conventional method of such dehydration (脱水) is to put food in chambers (室) through which hot air is blown at temperature of about ll0'C at entry to about 43'C at exit. This is the usual method for drying such things as vegetables, minced meat, and fish.

    Liquids such as milk, coffee, tea, soups and eggs may be dried by pouring them over a heated steel cylinder (圆筒), then put them into a chamber through which a current of hot air passes. In the first process, the dried material comes off the roller (滚筒) as a thin film which is then broken up into small, though still relatively flakes (薄片). In the second process it falls to the bottom of the chamber as small powder. Where recognizable pieces of meat and vegetables are required, as in soup, the ingredients (成分) are dried separately and then mixed.

    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.

56. It can be inferred from the passage that ________.

  A. the fattier fish contain as much water as the lean one

  B. the fattier the fish is, the more water it may contain

  C. a fatty fish holds less water than a lean one

  D. the water content of fish has nothing to do with the content of their fat

57. The underlined word "conventional" in Paragraph 3 can most probably be replaced by _________.

  A. particular        B. scientific          C. traditional               D. special

58. Which of the following statements is NOT true about drying food?

  A. The removal of water in food helps prevent it from going rotten.

  B. The open-air method of drying food has been known for hundreds of years.

  C. In the course of dehydration, the temperature of hot current coming from entry to exit is gradually going up.

  D. The process of drying liquids is much more complex than that of drying solid food.

59. The last paragraph mainly talks about __________.

  A. the reason why housewives like dried food

  B. the general convenience of dried food

  C. the methods of storing food

  D. the advantages of dried, canned and frozen food

     根据短文内容,从短文后的选项中选出能填入空白出的最佳选项。选项中有两项多余选项。

I was ten when I first sat with my grandmother behind the cashier(收银台)in her general store.   71    I quickly learned the importance of treating customers politely and saying “thank you.”

At first I was paid in candy.    72    I worked every day after school, and during the summer and on weekends and holidays from 8 a.m. to 7 p.m. My father helped me set up a bank account.   73   

By the time I was 12, My grandmother thought I had done such a good job that she promoted me to selling cosmetics(化妆品). I developed the ability to look customers directly in the eye. Even though I was just a kid, women would ask me such things as “ What color do you think I should wear?” I took a real interest in their questions and was able to translate what they wanted into makeup(化妆)ideas.   ___74  

The job taught me a valuable lesson: to be a successful salesperson, you didn’t need to be a Rocket scientist—you needed to be a great listener. __75___ Except they are no longer women purchasing cosmetics from me; instead, they are kids who tell me which toys they would like to see designed and developed.

A. Later I received 50 cents an hour.

B. Before long, she let me sit there by myself.
