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 participants 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,.
小题1:When your skin is exposed to sunlight long, it-becomes all of the following but _____.
A.flexibleB.coarseC.roughD.discolored
小题2:How wrinkled a person's skin is doesn't relate to _____.
A.the number of cigarettes a person smokes.

Iodine (碘)– rich salt was the hottest item on Chinese shelves Thursday, being snapped up (抢购) by shoppers after rumors spread that iodine intake could help protect one’s body from radiation damage, although the authorities have confirmed that the nuclear crisis in Japan had not affected China.
Rumors also spread about radioactive substances being leaked into ocean water that could pollute Chinese coasts.
The crazy buying has occurred nationwide, from the supposedly easily – harmed eastern coastal provinces to regions far – inland such as Xinjiang.
Supermarkets and convenience stores began reporting the lack of salt stocks from early Wednesday, with all salt sold out at many Carrefour and Wal – Mart stores. Some online clothes stores have begun offering salt as a bonus to customers.
Relevant government departments were trying hard to stop this round of panic – buying.
The Ministry of Health deniedthe rumor that eating more iodine – rich salt could repair damage from radiation, saying that it is technically impossible to absorb enough iodine for radiation prevention from eating salt.
The government urges the local market authorities to keep all salt sellers in check and to prevent storing and overpricing.
Also the spokesman of the government said that China’s seawater, as a source of salt, would not be affected by the nuclear crisis, as it would be impossible for radioactive substances to reach Chinese waters via the eastward ocean current.
“Reasons behind the salt rush include unclear information on the development of the nuclear crisis and terrifying media reports of the severity of a possible complete meltdown. If the fear of a Chernobyl – like catastrophe cannot be ended, the crazy buying will likely continue,” said a professor from Beijing University.
Beijing urged Tokyo Thursday to better release information at the Fukushima plant.
小题1:What caused the crazy buying of iodine – rich salt?
A.The rumor caused by the unclear information.
B.The shortage of iodine – rich salt in stores.

小题2:Some online clothes stores began offering salt as a bonus to customers because _______.

C.the customers prefer to buy salt on line       D.the salt from the on-line store is free
小题3:It’s quite clear that some sellers want to store iodine-rich salt is to _______.
A.increase the sales of related productsB.raise the price of products online
C.make more money from itD.meet the needs of the market
小题4:Why is it impossible for radioactive substances to reach Chinese waters?
A.The ocean is really too large.B.The distance from Japan is too far.

Angry survivors(幸存者)demanded answers on Sunday after a terrible accident at “Love Parade 2010”, a music festival in Germany, killed 19 people and left hundreds hurt.
The German Chancellor Angela Merkel expressed her shock over Saturday’s tragedy in the western city of Duisburg., “This was a very sad day,” Merkel said.
Witnesses(目击者)said that people pushed into the narrow tunnel, the only entrance to the Love Parade festival, from both sides until it was dangerously overcrowded. The panic began as festival-goers began to lose consciousness(意识)as they were crushed against the walls and each other. The dead included eight foreigners, from Australia, Italy, the Netherlands, China, Bosnia and Spain. More than 340 people were injured.

“The event was a real mess,” Patrick Guenter, a 22-year-old baker, said. “Although the festival was full, they kept letting people in,” he added. “It seems the organizers didn’t plan the route. And no one knew what was going on.” said Taggart Bowen-Gaddy, 20, an American from Philadelphia.
Officials said 4,000 police officers and 1,000 security guards provided security for the event, which attracted up to 1.4 million people.
“I warned one year ago that Duisburg was not a suitable place for the Love Parade. The city is too small and narrow for such events. It is a pity that…” German police union chief Rainer Wendt said.

China Daily Oct. 11----The ministry of Health has called for more awareness from the public on the mental health of the young, as part of efforts to make World Mental Health Day which fell on Friday.
More than 15 percent of Chinese youths have been found with mental problems, and about 30 million young people under 17 are suffering from depression, the Shang-based Wenhui Daily reported. The World Health Organization estimates that before 2020, the rate of children with mental problems will increase to 50 percent, and mental problems will become a major factor behind deaths and illness in the young worldwide.
Deng  Xiaohong, the spokesperson for the Beijing Municipal Health Bureau, said rapid changes are one of the reasons behind the rising number of youngsters with psychological problems. If these mental diseases are not addressed on time, occurrence of crimes, drug-taking and other dangerous behavior are expected to rise. Experts said mental diseases could be caused by many factors, such as the inability to handle interpersonal relations well, unstable emotions and pressures from an overload of studies. A number of experts have also said the one-child policy is another reason leading to poor mental health in the young. Children are said to be too “ spoiled” and “selfish” in a one-child family.
It’s reported  schools in many cities are rolling out measures to help students maintain their mental well-being. Yin Jingmiao, a teacher of the Beijing No.105 Middle School, told China Daily that the school invites psychologists to provide counseling to students three times a month.”  Students can be arranged to have 40-minute counseling sessions,” Yin said. The school also gives lectures on mental health to senior grade students before they take the national college entrance exams to help ease any anxiety arising from the tests.
小题1:Which of the following can be the best title for the passage?
A.Efforts to Mark World Mental Health Day
B.Seriousness of Youngsters’ Mental Health Problems
C.How to Maintain Mental Well-being
D.Public Awareness on Youngsters’ Mental Disease Expected
小题2:The writer intends to tell us in the second paragraph that________
A.mental health problems of the young are becoming a popular problem.
B.only young people are suffering from mental health problems.
C.mental problems will become as serious as deaths and illness.
D.the rate of children with mental problems will increase to 50 percent.
小题3:Which could be the consequence if the problem is left untreated?
A.Inability to handle interpersonal relations.B.Unstable emotions
C.Drug-taking and other dangerous behaviorD.Rapid social changes
小题4:Why is the Beijing No.105 Middle School mentioned in the passage?
A.To provide the students with counseling sessions.
B.To give an example showing how mental problems are dealt with.
C.To help ease the anxiety arising from the national college entrance exams
D.To call on other schools to learn from the No.105 Middle School

This is the VOA Special English Education Report. A few weeks ago, we talked about the Test of English as a Foreign Language, or TOEFL. A listener in Cambodia named Thida asks if American colleges and universities also accept the IELTS exam. IELTS is the International English Language Testing System. It was developed by the University of Cambridge ESOL examiners.
Cambridge ESOL says the test measures true-to-life ability to communicate in English for education, immigration or employment. The IELTS tests listening, reading, writing and speaking skills. It uses a mixture of accents and spellings, including British English and American English.
The test is used by government agencies, schools and professional organizations in one hundred and twenty countries. And, yes, that includes the United States. The many American schools that accepted the IELTS can be found on the Web at felts.org.
Some schools accept both the TOEFL and the IELTS, but the graduate school at Duke University in Durham, North Carolina, for example, says it prefers the IEITS.
The listening and speaking parts are the same for everyone who takes the IELTS, but people have a choice of reading and writing tests -- either academic or general training.
The listening test takes thirty minutes. There are forty questions based on a recording. The reading test takes sixty minutes. Students answer forty questions based on three written passages.
The writing test also takes sixty minutes. Students have to write two essays. One essay has to be at least one hundred and fifty words long and the other at least two hundred and fifty words. The shorter one is description of something; the longer one has to support and argument.
The speaking test takes less than fifteen minutes. The score is based on a recorded talk between the student and a test examiner.
And that's the VOA Special English Education Report, written by Nancy Steinbach. If you have a general question for our series, write to special@voanews.com. I'm Barbara Klein.
小题1:What does TOEFL stand for?
A.The Voice of AmericaB.The International English Language Testing System

A survey by an international temporary service agency found that U. S. managers believe that people with a sense of humour do better at their jobs, compared with those who have little or no sense of humour. In fact, about 96 percent of those surveyed said people with a sense of humour do better.
The survey went on to point out that the results suggest that a sense of humour may help light-hearted employees keep their jobs during tough times. And, what's more, it may push them up the corporate ladder past their humourless colleagues. Why? It seems that those with a sense of humour are better communicators and better team players.
Studies have shown that happy workers are more productive. In fact, a researcher at California State University found that humour could help the employees to release tension.
Research done by psychologist Dr. Ashton Trice at Mary Baldwin College in Virginia showed that humour helps us think. When people feel stuck on important projects, they tend to feel angry or depressed.  According to Dr. Trice's research, taking time out to laugh can help us to get rid of negative feelings and allow us to return to a task or move on to another project unaffected by past defeat.
If humour is really this important, then why don't we use it more often on the job? Most likely, the main reason is that many people are unaware of the positive effects of humour in the workplace. However, it is important to realize that some humour is not suitable for the workplace, and that it is often used at wrong times.
小题1: Most people think a sense of humour can ________.
A.help you to do your work better
B.make you have a rich life
C.make you pleased with your work
D.help you to make more friends
小题2:Many people don't use humour more in the workplace because __________.
A.they like keeping silent when working
B.they don't know the positive effects of humour
C.they think they should obey the rules
D.they don't like joking or laughing
小题3: A person without a sense of humour is easier __________.
A.to feel surprised
B.to get along with
C.to be worried
D.to be successful
小题4:What is probably the best title for the article?
A.People with a Sense of Humour.
B.Humour Is Important in the Workplace.
C.Humour and Humourless.
D.Everyone Likes Humour.
