In this(52)the North American Indians produce dried meat and make it into cakes, the Scandinavians make(53)fish and the Arabs make dried dates.
All foods contain(54), cabbage and other leaf vegetables contain as much as 93% water, potatoes and other root vegetables 80%, lean meat 75%, and fish anything from 80% to 60% depending(55)how fatty it is. If this water is(56), the activity of the bacteria which causes food to go bad is stopped.
Now day most foods are dried mechanically. The most common(57)of such drying is to put food in chambers. This is the usual method for drying such things(58)vegetables, minced meat, and fish.
Liquids such as milk, coffee, tea, soups and eggs may be dried(59)pouring them over a heated horizontal steel cylinder or by spraying them into a chamber through(60)a current of hot air passes. In the first(61),the dried material is scraped off the roller as a thin film which is then broken up into small pieces, though still relatively coarse flakes. In the second process it falls to the bottom of the chamber as a fine powder. Where(62)pieces of meat and vegetables are required, as in soup, the ingredients are dried separately and then mixed.

All foods contain water--cabbage and other leaf vegetables contain 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.
Nowadays most foods are dried mechanically. The conventional method of such dehydration(脱水) is to put food in chambers through which hoi air is blown at temperatures of about 110°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 horizontal steel cylinder or by spraying them into a chamber through which a current of hot air passes. In the first case, the dried material is scraped off the roller as a thin film which is then broken up into small, though still relatively coarse flakes. In the second process it falls to the bottom of the chamber as a fine powder.
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 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.
The chief point of the second paragraph is about ______.
A．the comparison of lean meat and fish
B．the removal of water in food
C．the water content in food
D．the relationship between water and food

Food and Health
The food you eat does more than provide energy. It can have a dramatic effect on your body’s ability to fight off heart disease, cancer, diabetes, high blood pressure, stroke, and weak bones. With remarkable consistency, recent research has found that a diet high in plant-based foods—fruits, vegetables, dried peas and beans, grains, and starchy staples such as potatoes—is the body’s best weapon in thwarting many health-related problems. These foods work against so many diseases that the same healthy ingredients you might use to protect your heart or ward off cancer will also benefit your intestinal tract and bones.
Scientists have recently estimated that approximately 30 to 40 percent of all cancers could be avoided if people ate more fruits, vegetables, and plant-based foods and minimized high-fat, high-calorie edibles that have scant nutritional value. Up to 70 percent of cancers might be eliminated if people also stopped smoking, exercised regularly, and controlled their weight. In the past, researchers had linked fat consumption with the development of cancers, but they currently believe that eating fruits, vegetables, and grains may be more important in preventing the disease than not eating fat. “The evidence about a high-fat diet and cancer seemed a lot stronger several years ago than it does now,” says Melanie Polk, a registered dietitian and director of nutrition education at the American Institute for Cancer Research.
The road to strong bones is paved with calcium-rich food. Leafy green vegetables and low-fat dairy products are excellent sources of calcium, the mineral that puts stiffness into your skeletal system and keeps your bones from turning rubbery and fragile. Your body uses calcium for more than keeping your bones strong. Calcium permits cells to divide, regulates muscle contraction and relaxation, and plays an important role in the movement of protein and nutrients inside cells. If you don’t absorb enough from what you eat to satisfy these requirements, your body will take it from your bones. Because your body doesn’t produce this essential mineral, you must continually replenish the supply. Even though the recommended daily amount is 1,200 mg, most adults don’t eat more than 500 mg. One reason may have been the perception that calcium-rich dairy products were also loaded with calories. “In the past, women, in particular, worried that dairy products were high in calories,” says Letha Y. Griffin, M. D., of Peachtree Orthopaedics in Atlanta. “But today you can get calcium without eating any high-fat or high-calorie foods by choosing skim milk or low-fat yogurt.” Also, low fat dairy products contain phosphorous and magnesium and are generally fortified with vitamin D, all of which help your body absorb and use calcium. If you find it difficult to include enough calcium in your diet, ask your doctor about supplements. They’re a potent way to get calcium as well as vitamin D and other minerals. But if you rely on pills instead of a calcium-rich diet, you won’t benefit from the other nutrients that food provides. Getting the recommended vitamin D may be easy, since your body makes the vitamin when your skin is exposed to the sun’s rays.
Which kind of food is recommended to prevent heart disease, cancer, diabetes, high blood pressure, stroke, and weak bones？______
A．Calcium-rich food.
B．Plant-based and starchy staples food.
C．High-fat, high-calorie food.
D．Vitamin D-rich food.

听力原文： Long ago, people had no way of keeping food from spoiling. So they ate all they possibly could and hoped it wouldn't be too long before the next meal. Mealtime was any time they found food, so they were either stuffed or starved most of the time.
No one knows for sure how people first learned to preserve food. Maybe they accidentally left food in the sun and discovered that the dried food kept longer. Maybe they left food by the fire and found out that cooked food not only kept longer, but tasted better. Somehow someone learned that salt helps preserve meat, fish and even vegetables. For example, pickles are cucumbers that are preserved with salt. Through the years people have continued to learn new and better ways of preserving food from one growing season to another. Today millions of people work in jobs that have something to do with food preservation.
Suppose you were walking up and down the aisles of a modern supermarket. On the shelves you would find food preserved in many different ways. You would see canned tomatoes and peaches in glass jars. These foods were first sealed in airtight containers and then heated to high temperature. If there was a break in the seal, the food would soon spoil You would also see dried and powdered food on the shelves. You would see prunes and raisins. You would see powdered milk and powdered eggs. Some dried foods, such as onions and potatoes, can of course be kept for tong.
If you walked past the dairy counter, you would find many foods that have been treated to kill any harmful germs that might have been in them. Milk is a good example. It may be unsafe to drink ram milk, that is, milk just as it comes from the cow. If the milk is heated and then cooled, the harmful germs are killed. The man who discovered this way of treating milk was a Frenchman named Louis Pasteur. Milk so treated is called pasteurized milk and the process is called pasteurization.
In the supermarket you would also find many frozen foods, frozen fruits, vegetables, meat and fish. Because techniques for freezing food are being improved, more and more frozen foods are appearing on the market, and more and more people are buying them. Fruits and vegetables sold in the supermarket are often frozen as soon as they are picked. The sooner fruits and vegetables are frozen, the better freezing machines can be taken into fields where the food grows, so that little time is lost between picking and freezing.
Many Americans with large families now have their own freezers and freeze their own food. Because fruits and vegetables are cheaper when they are in season, a housewife often buys more than she can use in a few days or even in a week and then freezes the rest. Preparing food for the freezer is a fairly simple process. To prepare strawberries, for example, the housewife simply needs to clean them, put them on a tray in the freezer for a few hours, then put them in plastic bags. Bread, cakes, cooked and uncooked pies can also be kept in a freezer.
With the improvement in methods of food preservation, people no longer have to stuff one day and starve another. They can have a well-balanced diet all year round.
