　　You probably know the food pyramid (金字塔) well enough. It is a food pyramid with horizontal stripes (水平線). 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 (垂直線). 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 (好處). 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 (階梯) 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.

(4) The stripes in the new pyramid become thinner at the top be cause ________.

[　　]

A．you should eat less as you grow older

B．a(chǎn)ll foods in a food group give us different health benefits
