CHICAGO(Reuters)-Smoking not only can wrinkle(皱纹)the face and turn it yellow—it can do the same to the whole body，researchers reported on Monday．
The study，published in the Archives of Dermatology，shows that smoking affects the skin all over the body-even skin protected from the sun．
“We examined non-facial skin that was protected from the sun，and found that the total number of packs，of cigarette smoked per day and the total years a person has smoked were linked with the amount of skin damage a person experienced，”Dr．Yolanda，who led the study，said in a statement.
“In participants older than 65 years，smokers had significantly more fine wrinkling than nonsmokers．Similar fmdings were seen in participants aged 45 to 65 years．” Yolanda’s team added in their report．
The researchers tested 82 people，smokers and nonsmokers，taking pictures of the inner right arms．They ranged，in age from 22 to 91 and half were smokers．In dependent judges decided how wrinkled each person’s skin was.
When skin is exposed to sunlight，especially the face，it becomes coarse(粗糙的)．Wrinkled and discolored with a pale yellow tint，Yolanda's team wrote．
Several previous studies have found that cigarette smoking led to premature(过早的)skin aging asmeasured by facial wrinkles，the study said，but little has been done to measure the aging of skin not exposed to light．
The report did not discuss die mechanism involved but previous research has found that cigarette smoke，among other things，causes blood vessels(血管)beneath the skin to constrict(紧缩)，reducing blood supply to the skin．
Smoking can also damage the connective tissue(组织)that supports both die skin and the internal organs.The best title for this passage would be ______________．
| A．The danger of smoking | B．Smoking causes skin aging |
| C．Quit smoking for health | D．A survey of smokers |
It can be inferred from the study _____________．
| A．smoking won’t affect skin protected from the sun |
| B．smoking will do damage to skin rather than other organs |
| C．smokers over 65 usually won’t worry about their skin |
| D．the age of smokers is not connected，with the result of the test |
When your skin is exposed to sunlight long，it becomes all of the following but _________.
| A．flexible | B．coarse |
| C．rough | D．discolored |
According to the passage，how wrinkled a person’s skin is doesn’t relate to ___________．

| D．introduce a new way of avoid skin aging |
Across the world, 1.1 billion people have no access to clean drinking water. More than 2.5 billion people lack basic sanitation.(卫生设备)
The combination proves deadly. Each year, diseases related to inadequate water and sanitation kill between 2 and 5 million people and cause an estimated 80 percent of all sicknesses in the developing world. Safe drinking water is a precondition for health and the fight against child death rate, inequality between men and women, and poverty.
Consider these facts:
●The average distance that women in Africa and Asia walk to collect water is 6 kilometers.
●Only 58 percent of children in sub-Saharan Africa are drinking safe water. and only 37 percent of children in South Asia have access to even a basic toilet.
●Each year in India alone, 73 million working days are lost to water-borne diseases.
Here are three ways you can help:
1)Write Congress
Current U.S. foreign aid for drinking water and sanitation budgets only one dollar per year per American citizen. Few members of Congress have ever received a letter from voters about clean drinking water abroad.
2)Sponsor a project with a faith-based organization
Many U.S. religious groups already sponsor water and sanitation projects, working with partner organizations abroad. Simply put a single project by a U.S. organization can make safe water a reality for thousands of people.
3)Support nonprofit water organizations
Numerous U.S.-based nonprofits work skillfully abroad in community-led projects related to drinking water and sanitation. Like the sample of non-profits noted as follows, some organizations are large, other small-scale, some operate worldwide, others are devoted to certain areas in Africa, Asia, or Latin America. Support them generously.
The three facts presented in the passage are used to illustrate that________.
| A．poverty can result in water-borne diseases |
| B．people have no access to clean drinking water |
| C．women’s rights are denied in some developing countries |
| D．safe drinking water should be a primary concern |
The intended readers of the passage are________.
| A． Americans |
| B．overseas sponsors |
| C． Congressmen |
| D． U.S.-based water organizations |
The main purpose of the passage is to call on people to _________.
| A．get rid of water-related diseases in developing countries |
| B．donate money to people short of water through religious groups |
| C．fight against the worldwide water shortage and sanitation problem |
| D．take joint action in support of some nonprofit water organizations |
What information will probably be provided following the last paragraph?
| A．A variety of companies and their worldwide operation. |
| B．A list of nonprofit water organizations to make contact with. |
| C．Some ways to get financial aids from U.S. Congress. |
| D．A few water resources exploited by some world-famous organizations. |
Although man has known asbestos for many hundreds of years, it was not until 160 years ago that it was mined for the first time on the North American continent. H. W. Johns, owner of a New York City Supply Shop for roofers, was responsible for(对…负责) the opening of that first mine.
Mr. Johns was given a piece of asbestos which had been found in Italy. He experimented with the material and then showed its surprising powers to his customers. After putting on a pair of asbestos gloves, which looked much like ordinary work gloves, he took red-hot coals from the fireplace and played with them in his hands. How astonished the customers were to discover that he was not burned at all. You can well imagine that he had increasing business in asbestos roofing materials. However, because it was very expensive to transport (carry) them from Italy to the United States, Mr. Johns sent out a young scientist to seek a source nearer home. This young man found great vein(岩脉), in the province of Quebec in Canada.
Ever since 1881 Quebec has led the world in the production of this unusual mineral, which is made up of magnesium, silicon, iron, and oxygen. When it is mined, the asbestos is heavy, just as you would expect a mineral to be. When it is separated, a strange thing happens; the rock breaks down into fine, soft, soapy fibres(纤维).
Scientists do not know why the rock can be separated easily into threads(线), but they have found thousands of uses of this fireproof material, of the so-called “cloth of stone”.Which title best expresses the main idea of this passage?
| A．Asbestos mined in Canada | B．Fireproof matter |
| C．A “wonder” mineral | D．A new roofing material |
Johns proved his ability as a salesman by_______.
| A．going into roofing business | B．carrying asbestos from Italy |
| C．sending a trained scientist | D．showing the use of asbestos gloves |
Which is the most important character of asbestos that the author wants to show us?
| A．It is like thread. | B．It feels soapy. |
| C．It burns easily. | D．It is unusually heavy. |
The author’s main purpose in writing this passage was to _______.
| A．show the need for more scientists |
| B．compare asbestos with other minerals |
| C．increase the sales of asbestos |
| D．present facts about asbestos |
The blue tits(山雀) have been inspecting the nest-box again this year. The male is the house-hunter but the female will make the final choice. He lands at the hole and turns his head to expose his white cheeks as a signal to attract the female from where she has been feeding.
Among many birds that nest in holes, the male has a light-coloured patch on its plumage(鸟羽) which acts as signal for drawing the female’s attention to a suitable nesting-place. Unlike the blue tit, the redstart(红尾鸲) may be only the male that strikingly coloured and the female is not beautiful.
A few years ago I was lucky enough to spot a pair of redstarts in action in a Walsh wood. The male was leading an interested female to holes that he had previously(先前) checked out. He sat at the entrance of each hole and put his head on to show off his white forehead, or his head in to reveal(显露) his tail.
If the female failed to react to his visual signals, the male sometimes sang for extra effect, while gliding towards her on spread wings and tail. Once the female accepts by following the male through the hole the displays stop, you must be at the right place at the right time to watch them. How do the blue tits choose their nest?
| A．They choose their nest together. |
| B．The male chooses their nest. |
| C．The house-hunter chooses their nest. |
| D．The female chooses their nest. |
The writer was lucky to see ________.
| A．how the male made his tricks |
| B．how an interested female played with the male happily |
| C．what the male displayed and won the female |
| D．that the male tried his best but failed to attract the female |
You can spot a pair of redstarts in a Walsh wood ________.
| A．at any time | B．regularly | C．in April | D．occasionally |
The writer is probably ________.
| A．a bird expert | B．a bird-hunter |
| C．a bird raiser | D．a scientist |
When you are in another country, it is important to know the language, but it is equally important to know how to communicate nonverbally(非语言地), before saying anything by making gestures. According to a pioneer in nonverbal communication, only 30 to 35 percent of our communication is verbal. When people don't know the language, the most common way to communicate is through gestures. However, many gestures have different meanings, or no meaning at all, in different parts of the world.
In the United States, for example, nodding your head up and down means “yes”. In some parts of Greece and Turkey, however, this motion can mean “no”. In Southeast Asia, nodding your head is a polite way of saying “I've heard you”.
In ancient Rome, when the emperor wanted to spare someone's life, he would put his thumb up. Today in the United States, when someone puts his / her thumb up, it means “Everything is all right”. However, in Sardinia and Greece, the gesture is insulting and should not be used there.
In the United States, raising your clasped hands above your head means “I’m the champion” or “I’m the winner”. It is the sign prizefighters make when they win a fight. When a leading Russian statesman(政治家) made this gesture after a White House meeting, Americans misunderstood and thought he meant he was a winner. In Russia, however, it is a sign of friendship.
In the United States, holding your hand up with the thumb and index finger in a circle and the other three fingers spread out means “Everything is O.K.” and is frequently used by astronauts and politicians. In France and Belgium, it can mean “You’re worth nothing.”
There are other nonverbal signals that people should be aware of when they go to another country, such as the distance to maintain between speakers. Americans usually feel comfortable when speaking with someone if the distance between them is about eighteen inches to arm’s length. Anything closer makes them feel uncomfortable.
When talking to Americans, it is also important to make eye contact. If you look down when talking to an American, he / she may feel that you are embarrassed, afraid, or trying to hide something.
In addition to knowing how to communicate nonverbally in a country, it is important to know what you and he cannot discuss. In the United States, there are certain topics to avoid when you first meet someone, For example, don’t ask people their age, weight, religion, marital status(婚姻状况), how much money they earn, or how much something costs. You can talk about work, the weather, traffic problems, sports, food, news of the day, where one lives, consumer subjects (computers, car repairs, and so forth), and travel or vacation plans.
These few examples illustrate that your actions can speak louder than your words. In a particular cultural contest, what you say and what you don’t say are equally important. Which of the following is true?
| A．People all over the world only communicate verbally. |
| B．Most of our gestures have no meaning at all. |
| C．Some people think that 65 to 70 percent of our communication is nonverbal. |
| D．Gestures are the most common way to common way to communicate. |
As we can see from the passage there are ______ kinds of nonverbal communication signals.
| A．four | B．five | C．six | D．seven |
Please paraphrase the clause“…your actions can speak louder than your words.
| A．Your deeds are better than your words |
| B．What you do is better than what you say |
| C．You try to show your best manners |
| D．you are better understood by your gestures than through your words |
The main idea of the passage is that when you are in another country, ______.
| A．it is unimportant to know the language |
| B．it is important to know what you can talk about to a foreigner |
| C．to know how to communicate nonverbally is as important as to know the language |
| D．to communicate the rough gestures is more important than to know the language |
I came to live here where I am now between Wounded Knee Greek and Grass Greek. Others came too, and we made these little grey houses of logs that you see, and they are square, It is a bad way to live, for there can be no power in a square.
You have noticed that everything an Indian does is in a circle, and that is because the Power of the World always works in circles, and everything tries to be round. In the old days when we were a strong and happy people, all our power came to us from the respectful circle of the nation, and so long as the circle was unbroken, the people were getting rich. The flowering tree was the living center of the circle, and the circle of the four quarters nursed it. The east gave peace and light, the south gave warmth, the west gave rain, and the north with its cold and strong wind gave strength and continuous power. This knowledge came to us from the outer world with our brief. Everything the Power of the World does is done in a circle. The sky is round, and I have heard that the earth is round like a ball, and so are all the stars. Birds make their nests in circle, for theirs are the same as ours. The sun comes forth and goes down again in a circle. The moon does the same, and both are round. Even the seasons form a great circle in their changing, and always come back again to where they were. The life of a man is a circle from childhood to childhood, and so it is in everything where power moves. Our places were like the nests of birds, and these were always set in a circle, the nation’s circle, a nest of many nests, where the Great Spirit meant for us to nurse our children.
But the Wasichus (Indian word for “white people”) have put us in these square boxes. Our power is gone and we are dying, for the power is not in us any more. You can look at our boys and see how it is with us. Where we were living by the power of the circle in the way we should, boys were men at twelve or thirteen years of age. But now it takes them very much longer to be bull - grown. According to the passage, the Indians _______.
| A．don’t have modern instruments in their homes |
| B．refused to move from round places |
| C．lived in round places, but were forced to live in square houses |
| D．lived in round places, but then decided to move into square houses |
Two things being compared in the passage are _______.
| A．the Indians’ past and present living conditions |
| B．the Indians’ past and modern beliefs |
| C．the Indians’ old and new power |
| D．people and nature |
In the second paragraph “the four quarters” refers to _______.
| A．the four rooms of the Indian’s house |
| B．the four kinds of natural power |
| C．the four seasons |
| D．the four directions |
According to the author, once the Indians moved into square houses, _______.
| A．they had to move to other houses |
