Passage Four
Increasingly, over the past ten years, people -- especially young people have become aware of the need to change their eating habits, because much of the food they eat, particularly processed food, is not good for the health. Consequently, there has been a growing interest in natural foods: foods which do not contain chemical additives and which have not been affected by chemical fertilizers, widely used in farming today.
Natural foods, for example, are vegetables, fruit and grain which have been grown in soil that is rich in organic matter. In simple terms, this means that the soil has been nourished by unused vegetable matter, which provides it with essential vitamins and minerals. This in itself is a natural process compared with the use of chemicals and fertilizers, the main purpose of which is to increase the amount-- but not the quality -- of foods grown in commercial farming areas.
Natural foods also include animals which have been allowed to feed and move freely in healthy pastures. Compare this with what happens in the mass production of poultry: there are battery farms, for example, where thousands of chickens live crowded together in one building and are fed on food which is little better than rubbish. Chickens kept in this way are not only tasteless as food; they also produce eggs which lack important vitamins.
There are other aspects of healthy eating which are now receiving increasing attention from experts on diet. It is significant that nowadays fiber is considered to be an important part of a healthy diet. In white bread, for example, the fiber has been removed. But it is presented in unrefined flour and of course in vegetables. It is interesting to note that in countries where the national diet contains large quantities of unrefined flour and vegetables, certain diseases are comparatively rare. Hence emphasis placed on the eating of whole meal bread and more vegetables by modem experts on "healthy eating."

A dolphin(海豚)looks more like a fish than certain fishes do. It is an excellent swimmer. The dolphin seems to flash through the water. Like fish, dolphins are completely at home in the water. There they play, feed, sleep, and give birth to their young. Dolphins live in the sea and can live only in the sea.
Yet they are not fish. A dolphin must come to the surface to breathe. Fish can take oxygen from the water. Dolphins cannot. Like us, they breathe with lung and must take their oxygen from the air. And they are mammals(哺乳动物).
Most mammals are land animals. Dolphins are evolved(进化)from land animals. Long ago, dolphin ancestors(祖先)left the land for the sea. Among the animals was a kind that would become the dolphin we know. No one is sure exactly what kind of animal it was. But there is reason to think it was related to grass-eating animals like the cow. Modern dolphins are fish-eaters.Yet their stomachs are like those of animals that eat plants. The make-up of their blood is also like that of grass-eating animals.
Dolphins are evolved from ______.

A:fish-eating mammals. B:sea animals. grass-eating fish. C:land animals.

Breakfast is not only the most important meal of the day, it is also the most neglected or skipped. Common reasons for not eating breakfast include lack of time, not feeling hungry, traditional dislike for breakfast, and dieting.
Breakfast simply means "break the fast." Your body spends at least six to twelve hours each night in a fasting state. In the morning your body needs energy to rev up (转动起来) into high gear for the day’s work ahead.
If you skip breakfast, you are likely to concentrate less effectively in the late morning, feel irritable, short-tempered (易怒的), tired, or weak.
When you choose not to eat breakfast, your body stays in slow gear. Also, people who skip breakfast often binge (无节制地大吃) later in the day at other meals or eat a high - calorie (高卡路里) snack in the morning. Breakfast eaters tend to eat less fat during the day, have more strength and endurance and better concentration and problem -solving ability.
A good breakfast should provide up to 1/3 of your total calorie needs for the day. On the average, we eat 400 less calories for breakfast than for dinner. If breakfast doesn’t appeal to you in the morning, try eating a lighter dinner earlier in the evening or save half your dinner for breakfast in the morning.
If you still aren’t hungry in the morning, start with something small like juice or toast or have a mid -morning snack later when you are hungry.
Not eating breakfast can also cause you to overeat, since a fall in blood sugar often makes you feel very hungry later. To make matters worse, since your body is in a slowed state, it will not be able to burn those extra calories very efficiently. If you feed your body healthy snacks and meals throughout the day, you are less likely to become extremely hungry and stuff yourself as soon as you begin to eat.
Since breakfast is the first and most important meal of the day, choosing the right fuel is important. The best breakfast foods are fruits, juice, lean meat, and grain products such as breads, rice, noodles, and cereals.
Which of the following is a healthy eating habit

A:Eating as little as possible. B:Eating no breakfast. C:Eating three regular meals a day. D:Eating no lunch.
