概括段落大意和补全句子。

Our Muscles

(1)When we think of muscles, we might often picture a bodybuilder with big arm and leg muscles. But our muscles do not have to look like that to work well.

(2)As a matter of fact, every time we write our name, we use the 20 different muscles in our hand. Every time our heart beats, we use our cardiac muscle(心肌) . When we eat our food, we use our tongue muscles. We even use muscles when we open and close our eyes. In fact, every time we move, we use some of the muscles in our body.

(3)A muscle is made of tiny fibers. Fiber is a type of tissue that feels a little like a rubber band. Thousands of these fibers are packed together to make a single muscle. We all have the same number of muscles----about 700 or so. Men and women with big muscles simply have thicker bundles of fibers.

(4)There are three different types of muscles in our body. Smooth muscles are the ones that we cannot control. They work quietly to keep our body running. Also, they are the ones that help us to absorb our food. The cardiac muscle makes the heart pump blood in and out. Skeletal muscles are the ones that we can control. These are the muscles that we use to raise our hands, or ride our bicycles.

(5)Even our face often uses muscles. But if we want to save our energy, try smiling instead of frowning. Remember that it takes 17 muscles in our face to smile, but 43 muscles to frown!

ver？ If you have, don’t feel alone! It’s a very common, natural wish that has a long history.Spanish explorers of the sixteenth century even tried to find a fountain of youth in what is now the state of Florida.The water the this legendary fountain, which no one has yet found, was believed to restore youth and good health to those who drank it.

Biologists today don’t expect that anyone will find a magical fountain of youth.Growing older is a natural part of the life cycle that can’t be reversed.As human beings grow older, organs such as the heart and lungs may stop functioning properly.Sight and hearing may become weak.And the human body becomes more likely to come down with serious illnesses from which it cannot recover.

Considered together, changes that bring about the decline of an organism are called aging.Because of aging, many biologists believe that there may be a maximum age limit to which even the healthiest organisms can live.For human beings, this maximum age limit is about 110 years.

Perhaps the most important thing that you can learn from your study of human biology is that you have a lot of control over the aging process in your own life.In fact, within our control are many physical and mental factors that have much to do with aging.For example, each of us, as recent research indicates, can do many things to help prevent heart and vessel disease, which causes half the death each year in the United States.We can avoid eating a lot of fatty meat.Eating too much of these types of animal fats can lead to the clogging and hardening of blood vessels.We can cut back on smoking and hopefully quit entirely.We can limit the amount of alcohol we drink and the amount of sugar we eat.We can exercise regularly and strengthen the heart and other organs.And we can remember to take time out each day for ourselves, time just relax.Exercise, recreation and relaxation all reduce stress – inner tension that is hard on all body organs.

One final thing we can do is to try to keep aware of advances made in health education.Information is often available free of charge from health clinics or schools.
