The whole body is covered with skin.The surface of the skin is dead(like the hair and the nails),but it is made from a living layer(层)just under the surface.The outside dead layers wear off(磨损)all the time,with new ones replacing them,and the body forms a totally new skin every three weeks.
The skin protects the body from the outside world and it passes information from the outside.It helps to keep water in the body and to keep the body at the same temperature.Becteria(细菌)can’t get in through the skin unless it is damaged.
If the weather is cold,the blood vessels(血管)in the skin squeeze down,or contract(收缩),so that as little blood as possible comes near the surface.This means that less warmth is lost to the outside.This makes the skin look pale,or even “blue”.At the same time,the hairs on the skin are pulled upright by tiny muscles.
When it is hot,the blood vessels expand(扩大),or get wider again,to allow plenty of blood to run near the surface of the skin.This helps the body to lose heat,and the skin may look red.At the same time,the sweat glands(汗腺)produce more sweat,which cools the skin.
If your skin has ever been numb(麻木的),you will realize how important the feeling from the skin is.Nerves(神经)in the skin are sensitive(敏感的)to heat and cold,sharpness,hardness and softness,wetness and dryness and pain.If one is not able to feel these things,which can act as warnings,he is likely to be burned,cut or hurt in other ways.
The colour of the skin depends on special colour cells(细胞).These are just below the top layers of the skin.They are needed as protection from some harmful ray of the sun.The stronger the sun is,the more important it is to have a dark skin.People with pale skins may “tan”(晒黑)in the sun.This happens when the body produces extra colour cells in the skin for protection.In the sun,the skin produces a vitamin(vitamin D)which is needed for strong bones.

Reading to oneself is a modern activity which was almost unknown to the learned in the early days of the history, while during the fifteenth century the term “reading” undoubtedly meant reading aloud. Only during the nineteenth century did silent reading become popular.
One should be careful, however, of supposing that silent reading came about simply because reading aloud is distraction（分散注意力）to others. Examination of reasons connected with the historical development of silent reading shows that it became the usual mode of reading for most adult reading tasks mainly because the tasks themselves changed in character.
The last century saw a gradual increase in literacy（读写能力）and thus in the number of readers. As readers increased, so the number of listeners dropped, and thus there was some reduction in the need to read aloud. As reading for the benefit of listeners grew less common, so came the popularity of reading as a private activity in such public places as libraries, trains and offices, where reading aloud would disturb other readers in a way.
Towards the end of the century there was still heated argument over whether books should be used for information or treated respectfully, and over whether the reading of material such as newspapers was in some way mentally weakening. Indeed this argument remains with us still in education. However, whatever its advantages are, the old shared literacy culture had gone and was replaced by the printed mass media on the one hand and by books and magazines for a specialized readership on the other.
By the end of the century students were being advised to have some new ideas of books and to use skills in reading them which were not proper, if not impossible, for the oral reader. The social, cultural, and technological developments in the century had greatly changed what the term “reading” referred to.Why was reading aloud common before the nineteenth century?
| A．Because silent reading had not been discovered. |
| B．Because there were few places for private reading. |
| C．Because few people could read for themselves. |
| D．Because people depended on reading for enjoyment. |
The development of silent reading during the nineteenth century showed_______.
| A．a change in the position of literate people |
| B．a change in the nature of reading |
| C．an increase in the number of books |
| D．an increase in the average age of readers |
Educationalists are still arguing about__________.
| A．the importance of silent reading |
| B．the amount of information provided by books and newspapers |
| C．the effects of reading on health |
| D．the value of different types of reading material |

In modern society there is a great deal of argument about competition . Some value it highly , believing that it is responsible for social progress and prosperity . Others say that competition is bad ; that it sets one person against another ; that it leads to unfriendly relationship between people .
I have taught many children who held the belief that their self-worth relied (依赖)on how well they performed at tennis and other skills . For them, playing well and winning are often life-and-death affairs. In their single-minded pursuit ( 追求)of success , the development of many other human qualities is sadly forgotten .
However ，while some seem to be lost in the desire to succeed , others take an opposite attitude .In a culture which values only the winner and pays no attention to the ordinary players , they strongly blame competition . Among the most vocal are youngsters who have suffered under competitive pressures from their parents or society . Teaching these young people . I often observe in them a desire to fail . They seem to seek failure by not trying to win or achieve success . By not trying , they always have an excuse : “I may have lost . but it doesn’t matter because I really didn’t try . “What is not usually admitted by themselves is the belief that if they had really tried and lost, that would mean a lot . Such a loss would be a measure of their worth . Clearly, this belief is the same as that of the true competitors who try to prove themselves . Both are based on the mistaken belief that one’s self-respect relies on how well one performs in comparison with others . Both are afraid of not being valued . Only as this basic and often troublesome fear begins to dissolve (缓解) can we discover a new meaning in competition .What does this passage mainly talk about ?

LONDON—Archaeologists have discovered a smaller prehistoric(史前) site near Britain’s famous circle of standing stones at Stonehenge.
Researchers have named the site “Bluehenge” after the color of the 27 Welsh stones that were laid to make up a path. The stones have disappeared, but the path of holes remains.
The new circle, unearthed over the summer by researchers from Sheffield University, represents an important find, researchers said Saturday. The site is about a mile away from Stonehenge.
Bluehenge, about 80 miles southwest of London, is believed to date back to about the time Stonehenge was built, about 5,000 years ago.
Mike Parker Pearson of Sheffield University said he believed the path and stonehenge itself were linked to rituals(仪式) of life and death.
Mike Parker suggested that the ancient funerary rituals began at a different circle site known as “Wood-henge”, which represented the world of the living. The bodies of the dead were then brought down the River Avon to Bluehenge, which represented death, and were finally carried along a ceremonial route known as the Avenue to Stonehenge.
Bournemouth University Professor Tim Darvill, an expert on Stonehenge, told Britain’s Dail Mail that Bluehenge “adds to the richness” of the ancient site’s story.
“This henge is very important because it forms part of the picture of ceremonial monuments in the area and puts Stonehenge into context,” Darvill was quoted(引述) as saying. “It’s no longer Stonehenge standing alone, but it has to be seen in context with the landscape.”How many henges are mentioned in this passage?
| A．Two | B．Three | C．Four | D．Five |
Who believed the Stonehenge is related to ancient ritual of death?
| A．Archaeologists from London | B．Welsh researchers |
| C．Mike Parker Pearson | D．Professor Tim Darvill |
What does the underlined sentence “It’s no longer Stonehenge standing alone, but it has to be seen in context with the landscape.” in the last paragraph mean?
| A．Stonehenge has noting to do with Bluehenge |
| B．Woodhenge represented the world of living in ancient times. |
| C．Bluehenge represented death |
| D．Stonehenge, Woodhenge and Bluehenge should be studied together |
From the passage we can learn that ______.
| A．researchers have named the site “Bluehenge,” because they have found blue huge stones there |
| B．funerary rituals were carried out along the path starting from Woodhenge, River Avon to Bluehenge, finally Stonehenge. |
| C．Bluehenge is 1 mile away from London |
| D．Bluehenge dates back to 2000 BC |
