　　You probably know the food pyramid (金字塔) well enough. It is a food pyramid with horizontal stripes (水平线). Carbohydrates (碳水化合物) , such as bread, rice and potatoes, are on the base of the pyramid. They are most of our everyday food. The fats and oils (脂油) are at the top of the pyramid. We should eat the least of them.

　　Well, the food pyramid has been built again and it looks a lot better. It is a food pyramid with vertical stripes (垂直线). Instead of the horizontal stripes, the vertical stripes mean the five food groups and fats and oils. Another change is that the stripes get thinner at the top of the pyramid. This is because not all foods in a food group give us the same health benefltS (好处). A fresh apple, for example, would be on the base of the pyramid, while an apple pie would be at the top. This shows that we can eat more fresh apples than apples in an apple pie. Another big change is the steps (阶梯) going up the side. This shows us how important exercise is. It also shows us that we will be healthier and healthier if we take exercise every day.

　　So why did some American experts change the pyramid? They did this to do a better job of telling people how to be healthy. The new pyramid tells us to have balanced (平衡的) food from each food group every day, and it shows us that we need less of some kinds of food than others. For example, you need less meat or fish than rice or fruit. It also shows us that not all foods in a group give us the same health benefits, and that exercise is quite important in our everyday life.

　　Careful and careless are as different as fire and water. But it is strange that quite a few scientists have both these qualities (品质). They are both careful and careless. Newton, the famous English scientist, was such a person.

　　Once Newton invited a friend to dinner at home. When they were ready to eat, Newton left to get a bottle of wine. But after his friend had waited for a long time, Newton still didn't come back. At last his friend found Newton was in the lab. When Newton was going to get the bottle of wine, he suddenly had a new idea for his experiment (实验) . So he forgot his friend and the dinner. Another time, Newton was leading a horse up a mountain, and held the rein (缰绳) in his hand. While he was walking, he kept thinking about problems. When he got to the top of the mountain, he found the rein was not in his hand and that the horse was missing.

　　Einstein was another example. Once he was waiting for a friend at a bridge. While waiting, he became lost in thought. It started to rain. The rain kept on for some time. When he took out a piece of paper to write something down, the paper was wet and then he knew that it was raining. But after he put the paper into his pocket, he again forgot he was standing in the rain.
