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

Once upon a time (not so very long ago, either!) industrial goods were made to last forever. If you bought a ear or a stove, it was a once-in-a-lifetime investment(投资). You paid good money for it, and you took care of it. Nowadays industry has persuaded us that products shouldn't last a long time. It's cheaper to throw them away than it is to repair them. This has led directly to the "throw-away society" which is a tremendous waste of the earth's resources.
Just think of the cars that are traded in daily, just because they are out of style. Think of the expensive packaging material that is thrown away every time a new object is bought. And we consumers have to pay for that material! Our industrial society has turned us into spoiled children. This wastefulness has got ten us into the mess (困境) we are in now. When we have no resources left, then we'll start to take care of what we have. But why can't we act before this happens? Why can't we go back to being a society in which the prevention of waste is a virtue?
Products used to be made to last ______.
A.for at least five years
B.for ten years
C.for as long as you take good care of them
D.for your whole life

When a 13-year-old Virginia girl started sneezing, her parents thought it was merely a cold.Butwhen the sneezes continued for hours, they called in a doctor.Nearly two months later the girl wasstill sneezing, thousands of times a day, and her case had attracted worldwide attention.
Hundreds of suggestions, ranging from" put a clothes pin on her nose"to "have her stand on herhead" poured in.But nothing did any good.Finally, she was taken to Johns Hopkins Hospital whereDr.Leo Kanner, one of the world&39;s top authorities on sneezing, solved the baffling (难以理解的)problem with great speed.
He used neither drugs nor surgery, curiously enough, the clue for the treatment was found in anancient superstition about the amazing bodily reaction we call the sneeze.It was all in her mind, hesaid,a view which Aristotle, some 3,000 years earlier, would have agreed with heartily.
Dr.Kanner simply gave a modem psychological interpretation to the ancient belief that too muchsneezing was an indication that the spirit was troubled; and he began to treat the girl accordingly.
"Less than two days in a hospital room,a plan for better scholastic and vocational adjustment,and reassurance about her unreasonable fear of tuberculosis quickly changed her from a sneezer to anex-sneezer," he reported.
Sneezing has always been a subject of wonder, awe and puzzlement.Dr.Kanner has collectedthousands of superstitions concerning it.The most universal one is the custom of begging for theblessing of God when a person sneezes--a practice Dr.Kanner traces back to the ancient belief that asneeze was an indication that the sneezer was possessed of an evil spirit.Strangely, people over theworld still continue the custom with the traditional, "God bless you" or its equivalent.
When scientists look at the sneeze, they see a remarkable mechanism which, without any con-scious help from you, takes on a job that has to be done.When you need to sneeze you sneeze, thisbeing nature&39; s clever way of getting rid of an annoying object from the nose.The object may be justsome dust in the nose which nature is striving to remove.
The girl sneezed continuously because she__________. 查看材料
A.was ill
B.was mentally ill
C.had heavy mental burden
D.had attracted world-wide attention
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.

Another issue: in a True Mirror you seem to have far less control over the figure in the glass than you do in a normal mirror. If you turn to the right in front of a normal mirror, the image turns with you and ends up facing in the same direction, completing the visual palindrome (回文). In a True Mirror the image faces the other way, as if you were about to begin pacing off for a duel with yourself; and when you take a step, the image steps away from you. In a normal mirror your reflected finger comes out to meet your real one until they touch, like Michelangelo's God and Adam. In a True Mirror the reflected finger comes at you from the other side of the glass, as if pointed by the other hand. Ordinarily, you have no difficulty looking at a normal mirror and guiding your hand to an object reflected in it. Try this with a True Mirror, and your grasp will prove errant. Shaving becomes a blood sport. If all the review mirrors in America's cars were suddenly replaced by True Mirrors, there could be a very special episode of ER (美国电视剧《急诊室》).
In an ordinary mirror your right eye stares at your right eye and your left eye at your left eye--the opposite of the right-left, left-right connection we employ for assessing one another in the wild. The image in a True Mirror (which shows what you look like to others) can come as something of a shock. You tend to look the way you do in photographs, which for many people is also a shock. (This is the flip side (反面) of the start you sometimes get when looking at the reflected image of someone you are accustomed to seeing in person.) A newspaper headline held up to a True Mirror doesn't appear backward--it reads just fine. But your own face may seem oddly asymmetrical. Facial mannerisms nurtured in front of a normal mirror may in a True Mirror be revealed in a different light. "It is a wholly new view for many," the True Mirror's promotional literature concedes, "and not surprisingly, some don't like or feel uncomfortable with the new look."
