As many as 60,000 people worldwide die each year from too much sun, but simple safety steps could prevent many deaths, according to a World Health Organization report.
The report, released on Wednesday, was treated as the first overall look at the global health burden from UV radiation, which is linked to up to 90 percent of melanoma（恶性黑色素瘤） and other skin cancers. UV radiation can also cause sunburn, more rapid skin aging, eye diseases, and reactivation of the herpes（疱疹） virus that causes cold sores, and pterygium, a fleshy growth on the surface of the eye.
“We all need some sun, but too much sun can be dangerous—and even deadly,” said Dr Maria Neira, the director of WHO’s agency of public health and the environment, who released the report.
To prevent cancer and other diseases linked to UV radiation, the agency recommends that people:
— Limit time in the midday sun.
— Use shade wisely and seek shade when UV rays are most intense.
— Wear protective clothing, hats and sunglasses.
— Use sunscreen with a sun protection factor 15+.
— Avoid sunlamps and tanning parlours.
People under age 18 should not use them at all.
“The application of sunscreens should not be used to prolong sun exposure but rather to protect the skin when exposure is unavoidable,” the report warned.
The report also noted that the ground’s surface can make a difference:
— Fresh snow reflects as much as 80 percent of ultraviolet light.
— Sea foam reflects about 25 percent.
— Dry beach sand reflects about 15 percent.
Small amounts of exposure to the sun help the skin to produce vitamin D.
48. The report was highly spoken of mainly because ____.
A. it had listed up to 60,000 deaths from UV radiation
B. it related the deaths to UV radiation
C. it showed the advantages and disadvantages of UV
D. it found out the approaches to preventing deaths from UV radiation
49. According to Dr Maria Neira, which of the following is TRUE?
A. In fact we need only a small amount of sunlight.
B. Receiving large amounts of sunlight will cause deaths.
C. Midday sunlight has stronger UV radiation.
D. Melanoma will disappear if we follow the report’s advice.
50. As a construction worker, it is strongly recommended that ____.
A. he should stay inside the building B. he spread sunscreen on the face
C. he should wear good sunglasses D. he be equipped with sun protection
51. Which of the following can be the headline of the passage?
A. UV—A Deadly Killer From The Sun B. Melanoma Can Be Prevented Today
C. UV—A Great Need For Vitamin D D. Teenagers Mustn’t Stay Outside
Watercolor is the oldest paints known. It dates back to the early cave men who discovered they could add lifelike qualities to drawings of animals and other figures on the walls of caves by mixing the natural colors found in the earth with water.
Fresco(壁画), one of the greatest of all art forms, is done with watercolor. It is created by mixing paints and water and applying these to wet plaster(灰泥). Of the thousands of people who stand under Michelangelo's heroic ceiling in the Sistine Chapel, very few know that they are looking at perhaps the greatest watercolor painting in the world.
The invention of oil painting by the Flemish masters in the fifteenth century made fresco painting go down-hill, and for the next several centuries watercolor was used mainly for doing sketches(素描) or as a tool for study. It was not until the eighteenth and nineteenth centuries that English painters put back watercolor as a serious art form. The English have a widely-known love for the outdoors and also small, private pictures. The softness of watercolor had a remarkably strong attraction for them.
The popularity of watercolor continued to grow until in the twentieth century. The United States passed England as the center for watercolor, producing such well-known watercolor artists as Thomas Eakins and Andrew Wyeth.What is the passage mainly about?

“BANG!” the door caused a reverberation(回声).It was just standing there, with father standing on one side , and I on the other side.
We were both in great anger” Never set foot in this house again!” stormed father．With tears welling up in my eyes, I rushed out of the flat and ran along the street.
The street lights were shining rather desolately(凄凉的).I wandered aimlessly.
A young father who held a child in his arms walked past me．I felt as if I saw my childhood from another space: happy and harmonious.
But now..．I don’t know whether it is because I have grown up or because dad is getting old．We differ in our ways of thinking．He always imposes his opinions and codes of behavior on me．Whenever I do something wrong, he never admits it．We are just like two people coming from two different worlds．It feels like there is an iron door between us that can never be opened.
I wandered the streets, without a destination in mind．My heart was frozen on this hot summer night．As I walked on there were fewer and fewer people on the streets, until I had only the street lights to keep me company．When I finally reached the high-rise apartment block in which I lived ,I saw that the light was still on.
I thought to myself: “Is father waiting for me, or is he still angry with me?”
In fact, it was nothing．Perhaps, dad was throwing away some of his old stamps．Perhaps he thought they were useless．I never had the courage to tell him that I liked collecting stamps．I can’t stand his outrageous(蛮横的)words: “I can’t throw you away, let alone these old papers ?”
All the lights were off except father’s.
Dad was always like this．Maybe he didn’t know how to express himself．After shouting at me, he never showed any mercy or any moments of regret．After an argument he has the habit of creeping up in my sleep and then tucking me underneath the covers.
This was how he always was．He has been a leader for so long that telling everyone else what to do has become his second nature.
The light was still on．“Am I wrong?” I whispered ,maybe...With the key in hand, I was as nervous as I had ever been．At last, I decided to open the door．As soon as I opened the door tears ran down my cheeks．I suddenly realized that the iron door that I had imagined between us did not exist at all．Love—it second to none.Decide which is the best order of the following according to what happened in the passage.
a．I opened the door and entered the house.
b．Sadly I ran out into the street.
c．I reached the place where I lived and saw my house still brightly lit.
d．I thought of my father’s kindness towards me.
e．I walked about in the street without any aim.
| A．b,e,d,c,a | B．b,e,c,d,a | C．b,e,a,c,d | D．b,e,c,a,d |
What made the writer think of his childhood ?
| A．The sight of the desolate street lights. |
| B．The sight of the empty street. |
| C．The sight of a father with a child in his arms. |
| D．The sight of light in his own house. |
Why do you think the father often shouts at his son ?
| A．perhaps the father is getting older and older. |
| B．perhaps the son has already grown up. |
| C．perhaps they never agree with each other. |
| D．perhaps the father has got used to doing that. |
What conclusion can you draw after reading the passage ?

| B．The father is actually kind to his son. |
| C．The father is neither kind nor cruel to his son. |

Without most people realizing it, there has been a revolution in office work over the last ten years．Before that time, large computers were only, used by large, rich companies that could afford the investment．With the advancement of technology, small computers have come onto the market, which are capable of doing the work which used to be done by much larger and expensive computers, so now most smaller companies can use them
The main development in small computers has been in the field of word processors (处理器) , or WPS as they are often called．40% of British offices are now estimated to have a word processor and this percentage is growing fast．
There are many advantages in using a word processor for both secretary and manager．The secretary is freed from a lot of daily work, such as re-typing letters and storing papers．He or she can use this time to do other more interesting work for the boss．From a manager's point of view, secretarial time is being made better use of and money can be saved by doing daily jobs automatically outside office hors．
But is it all good? If a lot of daily secretarial work can be done automatically, surely this will mean that fewer secretaries will be needed．Another worry is the increasing medical problems related to work with visual display units (显示器)．The case of a slow loss of sight among people using word processors seems to have risen greatly．It is also feared that if a woman works at a VDU for long hours, the unborn child in her body might be killed．Safety screens to put over a VDU have been invented but few companies in England bother to buy them．
Whatever the arguments for and against word processor, they are a key feature (特征) of this revolution in office practice．
Then years ago, smaller companies did not use large computers because_________．
| A．these companies had not enough money to buy such expensive computers |
| B．these computers could not do the work that small computers can do today |
| C．these computers did not come onto the market |

over the last ten years is __________．
| A．the saving of time and money | B．the use of computers in small companies |
| C．the wide use of word processors | D．the decreasing number of secretaries |
It is implied but not directly stated in the passage that with the use of word
processors _________．
| A．some secretaries will lose their jobs |
| B．daily jobs can be done automatically outside office hours |
| C．medical problems related to work with a VDU have increased |
| D．the British companies will make less money |
Which of the following statements is NOT true?
| A．There are both advantages and disadvantages in using a word processor |
| B．The British companies care much for the health of the people using word processors． |
| C．The technology in the field of computers has been greatly advanced over the last ten years． |
| D．Using word processors , secretaries can get more time to do more interesting work for their bosses． |
It can be concluded from the passage that ________．
| A．safety screens are of poor quality |
| B．working at a VDU for a long time is good for one's health |
| C．more and more British offices will use word processors |
| D．British companies will need fewer and fewer manages |
Making an advertisement for television often costs more than a move．For example, a two-hour movie costs $ 6 million to make．A TV commercial can cost more than $ 6 000 a second．And that does not include cost of paying for air time(电视节目开始的时间)．Which is more valuable, the program or the ad? In terms of money--and making money is what television is all about the commercial is by far the more important．
Research, market testing, talent, time and money--all come together to make us want to buy a product．No matter how bad we think a commercial is, it works．The sales of Charm went up once the ads began．TV commercials actually buy their way into our head．We, in turn, buy the product．
And the ads work because so much time an attention are given them．Here are some rules of commercial ad making．If you want to get the low middle-class buyer, make sure the announcer has a tough, manly voice．Put some people in the ad who work with their hands．If you want to sell to upper-class audience, make sure that the house, the furniture, and the hair style are the types that the group identifies (识别) with．If you want the buyer feel superior to the character selling the product, then make that person so stupid or silly that everyone will feel great about himself or herself
We laugh at commercials．We don't think we pay that much attention them．But evidence shows we are kidding ourselves．The making of a commercial that costs so much money is not kid stuff．It's big, big business．And it's telling us what to think, what we need, and what to buy．To put simply, the TV commercial is a form of brainwashing．TV commercials are more important than other programs to television because _______．

Criticism is judgement．A critic is a judge．A judgement study and think about the material presented to him, accept it, correct it, or reject it after thinking over what he has read, watched or heard.
Another word for criticism is appreciation．When I criticize or appreciate some objector another, I look for its good points and bad points．In reading any printed or written matter, I always have a pencil in hand and put any comments in the book or on a separate paper．In other words, I always talk back to the writer.
That sort of critical reading might well be called creative reading because I am thinking along with the author, asking him questions, seeing whether he answers the questions and how well he answers them．I mark the good passages to store them in my memory piece of writing; where, how and why could or should I improve upon it?
You might think that doing what I suggested is work．Yes, it is, but the work is a pleasure because I can feel my brain expanding, my emotion reacting and my way of living change.
Reading exercises is a great influence on a person．If pictures, still or moving, accompany the reading, the memory will retain the material for a long time.
Just as evil books can corrupt, so also can good books gradually work a change on a corrupt person.
