There are different ways in which people try to deal with the problem of energy. One w

oking into garbage cans, the average family wastes at least $150 per year in food.

"Homemakers go out of their way to save pennies at the store and then don't realize that waste of edible (可食用的) foods adds up much more at home," said Dr. Rathji. He was one of about 100 food experts who met in Boise for a conference on food waste and ways to prevent it.

American families throw out between 8% and 20% of edible food at a cost of $4.5 billion per year. That's almost as much as the federal government spends every year for food stamps and child nutrition programs.

He found that food items which are costly and in short supply tend to be wasted more. During the 1973 meat shortage, meat waste increased to 9%, compared with 3% in 1974 and 1975. Sugar and sugar products waste jumped to 19% in 1975, when sugar prices doubled from the previous year.

Dr. Rathji theorizes that high prices force consumers to experiment, sometimes buy in large quantities. In the case of meat, sometimes low-priced cuts for unappetizing varieties are purchased, consumers then tend to waste more.

His theory is that the more variety in food bought, the more wasted. Regular bread is wasted at about a 10% rate, but specialty breads and rolls are wasted at a 20% rate.

If people are eating the same thing every day, they learn how to manage it. But if you're trying to pull something out of the cookbook every night, that's bound to be some waste.

Another finding is that lower income families waste less food than middle and upper income families. And the study found that dog food, which accounts for 8% of a shopping cart, is rarely wasted. Fresh produce and frozen items are more likely to be wasted.

The study also showed people with the most knowledge of safe, edible food waste the least. Much food is tossed out because a homemaker suspects it is spoiled when it is not.

The sea looks very pretty when the sun is shining on it. It can be very rough when there is a strong wind. The sea is very big. It covers three quarters of the globe! The sea is also very deep in some places. There is one spot near the Philippines , where the sea is about 11 kilometers deep. The highest mountain in the world is about 9 kilometers high. If that mountain was put in the sea at that place, there would still be 3 kilometers of water above it! What a deep place! In most parts of the sea, there are plenty of fishes and plants. Some live near the top of the sea. Others live deep down. There are millions of tiny living things that float in the sea. Many fish live by eating them. The sea can be very cold. When the diver goes downwards, the sea becomes colder and colder. When the diver goes deeper, the water exerts greater pressure.

. The tired mind gathers new energy. Once awake, the memory improves, and annoyance and problems are seen in a better perspective.

Some adults require little sleep; others need eight to ten hours in every twenty-four. Infants sleep sixteen to eighteen hours daily and, as they grow older, the amount gradually diminishes. Young students may need twelve hours; university students may need ten. A worker with a physically demanding job may also need ten, whereas an executive worker under great pressure may manage on six to eight. Many famous people are reputed to have required little sleep. Napoleon, Thomas Edison and Charles Darwin apparently averaged only four to six hours a night.

Whatever your individual need, you can be sure that by the age of thirty you will have slept for a total of more than twelve years. By that age you will also have developed a sleep routine: a favorite hour, a favorite bed, a favorite position, and a formula you need to follow in order to rest comfortably. Investigators have tried to find out how long a person can go without sleep. Several people have reached more than 115 hours ?nearly five days, whereas animals kept awake for from five to eight days have died of exhaustion. The limit for human beings is probably about a week.

When we talk about intelligence we do not mean the ability to get good scores on certain kinds of tests or even the ability to do well in school. By intelligence we mean a way of living and behaving, especially in a new situation. If we want to test intelligence, we need to find out how a person acts instead of how much he knows to do.

For example, when in a new situation, an intelligent person thinks about the situation, not about himself or what might happen to him. He tries to find out all he can do, and then he acts immediately and tries to do something about it. He probably isn’t sure how it all works out, but at least he tries. And if he cannot make things work out right, he doesn’t feel ashamed that he failed, he just tries to learn from his mistakes. An intelligent person, even if he is very young, has a special outlook in life, a special feeling about life, and a special way of how he fits into it.

If you look at children, you’ll see a great difference between what we call ”bright” children and “not bright” children. They are actually two different kinds of people, not just the same kind with different amounts of intelligence. For example, the bright child really wants to find out about life—he tries to get in touch with everything around him. But the unintelligent child keeps more to himself and his own dream world; he seems to have a wall between him and life in general
