CHICAGO （Reuters） - Smoking not only can wrinkle （起皱纹） the face and tarn 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 cigarettes smoked per day and the total years a person has smoked were linked with the amount of skin damage a person experienced," Dr．Yolanda Helfrich of the University of Michigan, who led the study, said in a statement．
"In p
articipants older than 65 years, smokers had significantly more fine wrinkling than nonsmokers．Similar findings were seen in participants aged 45 to 65 years," Helfrich "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．Independent judges decided how wrinkled each person' s skin was．
When skin is exposed to sunlight, notably the face, it becomes coarse, wrinkled and discolored with a pale yellow tint, Helfrich ' s team wrote．
Several previous studies have found that cigarette smoking contributes to premature（过早的）skin aging as measured 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 that supports both die skin and the internal organs,．When your skin is exposed to sunlight long, it-becomes all of the following but _____．
| A．flexible | B．coarse | C．rough | D．discolored |
How wrinkled a person's skin is doesn't relate to _____．
| A．the number of cigarettes a person smokes． |
| B．the kind and characteristics of skin |
| C．how long a person smokes |
| D．how long skin is under sunlight |
From the passage smoking results in skin aging mainly because _____.
| A．it will lower blood supply to skin |
| B．it can make you feel tired |
| C．it can make skin come off |
| D．it can make blood run faster |
The main purpose of the passage is to _____．

| B．advise people how to protect skin |
| C．warn people not to smoke again |
| D．introduce a new way of avoid skin aging |
LONDON (Reuters)—New faces given to a Chinese man after a bear tore off part of his face and a FrenchCaribbean man disfigured by a rare tumor show that such transplants can work and are not medical oddities (怪异)，researchers said.
The findings give hope to some people with severe facial disfigurement and suggest the transplants could prove longlasting without major problems.Despite the tissue rejection in the first year after their transplants，neither men had psychological problems accepting their new faces and have been able to rejoin society，they reported.
Only three people have received face transplants.The world’s first was carried out on French woman Isabelle Dinoire in November 2005 after she was disfigured in an attack by her dog.In 2007，her doctors reported that she had recovered slowly and steadily，overcoming two periods of rejection.
In 2006，Chinese doctors performed a face transplant on a 30yearold hit by a bear.While there were some complications with tissue rejection following the operation，two years later the man was doing well，his doctors said.“This case suggests that facial transplantation might be an option for restoring a severely disfigured face，and could enable patients to bring themselves back into society，” Shuzhong Guo and colleagues at Xijing Hospital in China wrote.
A French team described their work on a 29yearold man who suffered from Von Recklinghausen disease，an illness that changes the shape of his face.“The man，who was not named，was given a new nose，mouth and chin in a 2007 operation.He began to work 13 months after the transplant has more function in his face and has not rejected the new tissue，” his doctors said.
“Our case confirms that face transplantation is practical and effective for the correction of specific disfigurement，” Dr.Laurent Lantieri and colleagues at the HenriMondor hospital outside Paris wrote.What’s the main idea of this passage?

Although April did not bring us the rains we all hoped for, and although the Central Valley doesn’t generally experience the sound and lightning that can go with those rains, it’s still important for parents to be able to answer the youthful questions about thunder and lightning.
The reason these two wonders of nature are so difficult for many adults to explain to children is that they are not very well understood by adults themselves. For example, did you know that the lightning we see flashing down to the earth from a cloud is actually flashing up to a cloud from the earth? Our eyes trick us into thinking we see a downward motion when it’s actually the other way around. But then, if we believed only what we think and we see, we’d still insist that the sun rises in the morning and sets at night.
Most lightning flashes take place inside a cloud, and only a relative few can be seen jumping between two clouds or between earth and a cloud. But, with about 2,000 thunderstorms taking place above the earth every minute of the day and night, there’s enough activity to produce about 100 lightning strikes on earth every second.
Parents can use thunder and lightning to help their children learn more about the world around them. When children understand that the light of the lightning flashing reaches their eyes almost at the same moment, but the sound of the thunder takes about 5 seconds to travel just one mile, they can begin to time the interval (间隔) between the flash and the crash to learn how lose they were to the actual spark (闪光).According to the author, in the area of the Central Valley____.
| A．rains usually come without thunder and lightning. |
| B．it is usually dry in April |
| C．children pay no attention to the two natural wonders. |
| D．parents are not interested in thunder and lightning. |

What is TRUE about lightning according to the passage?
| A．Only a small number of lightning flashes occur on earth. |
| B．Lightning flashes usually jump from one cloud to another. |
| C．Lightning travels 5 times faster than thunder. |
| D．There are far more lightning strikes occurring on earth than we can imagine. |
The underlined word “activity” is most closely related to the word (s) _____.
| A．cloud | B．lightning strikes | C．lightning flashes | D．thunderstorms |
It can be concluded from the passage that _______.
| A．we should not believe what we see or hear. |
| B．things moving downward are more noticeable. |
| C．people sometimes may have wrong ideas about ordinary phenomena. |
| D．adults are not as good as children in observing certain natural phenomena. |

"Children should not be left unsupervised (无人监督的) to play with a dog." say experts in this week's British Medical Journal. Their advice is part of a review aimed at doctors who deal with dog bites.
"Dog bites and maulings are a worldwide problem, particularly in children." write Marina Morgan and John Palmer. Every year 250,000 people who have been bitten by dogs attend minor injuries and emergency units in the United Kingdom, and half of all children are reportedly bitten by dogs at some time, boys more than girls.
Accurate death figures are difficult to obtain, but in the past five years, two to three cases a year have made news headlines.
Based on the latest medical evidence, they advise doctors how to examine and treat a patient presenting with a dog bite. They discuss the risk of infection and when to refer to specialist care. For travelers bitten abroad, they suggest assessing the risk of rabies(狂犬病).
In terms of prevention, they suggest that children should be taught to treat dogs with respect, avoid direct eye contact, and not tease them. They should be taught not to approach an unfamiliar dog; play with any dog unless under close supervision; run or scream in the presence of a dog; pet a dog without first letting it sniff you; or disturb a dog that is eating, sleeping, or caring for its babies.
"Dog owners also need to change their behavior", says Rachel Besser, a children's doctor and lifetime dog owner, in an article.
"It is clear that not all dog owners appreciate that children should not be left unsupervised with a dog", she says. Just as some parents are obliged to take parenting classes, she would like to see compulsive classes for expectant dog owners to teach them about the responsibilities of dog ownership. Educational programs are also needed to teach children about some precautionary （预防的) behaviors around dogs.
Finally, she would like to see animal doctors advising dog owners about bite prevention, and doctors promoting bite prevention when treating patients who have been bitten by dogs.Dog biting is a problem which _____.
| A．only happens to a few children | B．should be paid attention to |
| C．only boys may meet with | D．has made news headlines |
The underlined word "they" in Paragraph 4 refers to "________" .
A. doctors B. parents C. experts D dog owners To avoid dog bites, a child should be taught to_____.
| A．have direct eye contact | B．approach an unfamiliar dog |
| C．run or scream in the presence of a dog | D．leave a dog feeding itself |
What are Rachel Besser's words mainly about?
| A．It's necessary to teach children how to raise dogs. |
| B．Children should be taught not to play with dogs. |
| C．All the dog owners would like to attend classes on caring for dogs. |
| D．Some dog owners would like children to be left unsupervised with a dog. |
Which of the following can be the best title for the passage?
| A．Dogs, Dangerous To Children |
| B．Children Should Know Behaviors Around Dogs |
