Muscles are stringly bundles of fibers varying from one five - thousand of an inch to about three inches. They have three unique characteristics, they can become shorter and thicker; they can stretch; and they can retract to their original positions. Under a high -powered microscope, muscle tissue is seen as long, slender cells with a grainy texture like wood.
More than half of a person' s body is composed of muscle fibers, most of which are involuntary, in other words, work without conscious direction. The voluntary muscles, those that we move consciously to perform. particular actions, number more than five hundred. Women have only 60 to 70 percent as much muscle as men for their body mass. That is why an average woman can' t lift as much, throw as far, or hit as hard as an average man.
According to the selection, the muscular sense is responsible for ______ .
A.the efficiency of our muscles
B.the normal breathing function
C.directing our muscles intelligently
D.the work of only our involuntary muscles
Archimedes is most well-known for one specific idea that he came up with. "Archimede's Principle" states that a solid object which is immersed in a liquid is pushed up by a force which is equal to the weight of the water that the object moves. For example, if you put a piece of wood and a piece of gold the same size in water, only the wood will float. Both the wood and gold move the same amount of water, but the wood weighs less than this water, while the gold weighs more.
It is believed that Archimedes discovered this principle when the king of Syracuse asked him to solve a problem. The king wanted to know if his crown was pure gold or a mixture of gold and silver. The king, of course, did not melt his crown to find out. The idea came to Archimedes as he lowered himself into his bath. He noticed how the water spilled out of the tub. He decided to use the same idea for the crown. He knew that a gold crown immersed in water would weigh more than one made of silver. The experiment was done and the goldsmith was proved guilty of trying to cheat the king.
A good title for the selection is ______.
A.Archimedes
B.Archimedes' Principle
C.A gold and silver crown
D.The king of Syracuse
People who are near-sighted can only see things that are very close to their eyes.' Everything else is not so clear. Many people who do a lot of close work, such as writing, reading and sewing, become near sighted. Then they have to wear glasses in order to see distant (远处的) things clearly.
People who are far-sighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm's length. If they want to do much reading, they must get glasses, too.
Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism (散光). This, too, can be corrected by glasses. Some people's eyes become cloudy because of cataracts (白内障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them."
Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle (角度). To prove this to yourself, look at an object out of one eye; then look at the same object out of the other eye. You will find the object's relation to the background (背景) and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distance as people with two eyes.
We should take good care of our eyes ______.
A.only when we cannot see perfectly
B.only when we can see well
C.even if we can see well
D.only when we realize how important our eyes are
When we see well, we do not think about our eyes very often. (79) It is only when we cannot see perfectly that we realize how important our eyes are.
People who are nearsighted can only see things that are very close to their eyes. Everything else seems blurry (模糊的). Many people who do a lot of close work, such as writing, reading and sewing, become nearsighted. Then they have to wear glasses in order to see distant objects clearly.
People who are farsighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm's length. If they want to do much reading, they must get glasses, too.

We're a nation of laws. Our courts are honest and they are independent. The President -- me -- I can't tell the courts how to rule, and neither can any other member of the government. Under our law, everyone stands equal. No one is above the law, and no one is beneath it.
All political power in America is limited and only given by the free vote of the people. We have a Constitution, now two centuries old, which limits and balances the power of the three branches of our government, the judicial(法庭的)branch, the legislative(立法的)branch, and the executive branch, of which I'm a part.
Many of the values that guide our life in America are first shaped in our families, just as they are in your country.American moms and dads love their children and work hard and sacrifice for them, because we believe life can always be better for the next generation. In our families, we find love and learn responsibility and character.
America is a nation guided by faith. Someone once called us "a nation with the soul of a church." This may interest you -- 95 percent of Americans say they believe in God, and I'm one of them.
