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,.

The new policy asked 800,000 employees to replace their former working schedule of 8:30 am to 5:30 pm with the new working hours of 9 am to 6 pm.
This is just one part of the Beijing municipal government’s plan to fight traffic jams. Starting April 1, daytime parking fees in 13 downtown areas were raised to encourage less driving. On April 2, the government announced limitations launched after the Beijing Olympics would be extended until April 2012. These ban Beijing’s 5.8 million drivers from driving one workday each week. The ban is based on the last number of the car license plate.
A multi-billion yuan fund has also been set up to build more underground ring roads in heavily populated areas. Major roads above ground will also be expanded.
According to Beijing’s traffic authorities, key projects include repairing major ring roads and expanding the subway network. The city will also create more taxi stops and bike rental stations, probably under the hundreds of overpasses (天桥) citywide.
Beijing’s fight against traffic jams is a smaller example of what is happening all around China. The central government is now supporting new ideas that will change the future of Chinese roads.
Bus rapid transit (BRT,快速公交系统) is one such idea. Special bus lanes carry almost as many passengers as a subway system. They cost less and are becoming popular in many big cities. Now Beijing has five BRT lines
Shanghai is dealing with traffic problems by charging higher fees for license plates(牌照). The city is also controlling the total number of plates sold. Now, it is considering a plan to charge cars for entering the central business district, as London does.
Meanwhile, there are signs that Chinese are more aware of the serious problem of traffic. For example, there has been a sharp increase in the number of posts looking for carpooling (拼车) partners on major websites.
By the end of March, 2010, China had 192 million cars, according to the Ministry of Public Security.
小题1: The article is mainly about___________.
A.the fight against traffic jams all around the world |
B.the increase of daytime parking fees in 13 downtown areas in Beijing |
C.the Beijing municipal government’s measures to reduce traffic jams |
D.news ideas that are likely to change the future of Chinese roads |
A.from 8:00 am to 5:00 pm | B.from 9 am to 6 pm |
C.from 8:30 am to 5:30 pm | D.from 7:30 am to 4: 30 pm |
A.adjustments to office hours | B.increases in daytime parking fees |
C.the extension of the limitations launched after the Beijing Olympics | |
D.charging higher fees for license plates |
A.the BRT system will become common China’s rural areas |
B.the Chinese government is aiming at changing the future of Chinese roads |
C.the Shanghai government has charged cars for entering the central business district |
D.here are enough ways to deal with traffic jams in Beijing |
Dios says it is the world’s first jumbo (unusually large) jet hostel, an actual jet-plane at Sweden’s main airport outside Stockholm which has been changed into a 25- room guesthouse that sleeps as many as 72 people.
“I learned about this plane that was standing deserted at Arlanda airport and I’ve been trying the concept of hostels in many different houses and buildings,” he told Reuters. “I thought, ‘Why not a plane?’”
Jumbo Hostels opened for business on Thursday, giving customers the chance to check in and sleep in a room that can best be described as comfortable.”
“The most challenging part with this project is trying to build something inside a metal hull(壳) – it’s just really, really tight.”
The jet, which was originally produced for Singapore Airlines, was taken out of service in 2002. It is held on a concrete foundation with the landing gear secured in steel cradles.
One feature of the hostel is its price – a room starts at 350 Swedish crowns (about $ 41), which is a lot less than hotel rooms outside of major airports.
Another feature is that customers can get married on the wing of the plane and stay in the plane’s more luxurious honeymoon suite (套房).
Instead of walking down the aisle in the church, lovebirds can take what Jumbo Hostels calls the “wing walk,” where they can be joined in great happiness at the wing tip. The hostel has someone ready to perform the ceremony.
But in some respects this hostel remains a plane – most customers have to share the jet’s nine bathrooms and the staff only wear air host and hostess outfits. The only room that has its own bathroom is the honeymoon suite.
小题1:Which of the following is not true?
A.The jet plane was out of use for over eight years |
B.The hostel provides ten bathrooms for customers |
C.The rooms in the hotel are comfortable |
D.The hostel lies at Arlanda airport in Stockholm |
A.air hostesses can offer good service |
B.a wedding ceremony can be held on the wing |
C.customers can sleep in comfortable rooms |
D.the staff can have a “wing walk” |
A.Because he is fond of plane very much. |
B.Because he is very curious |
C.Because he wants to earn more money. |
D.Because he likes trying the concept of hotel in many different things. |
A.call on people to make use of the deserted things |
B.describe a wonderful place for weddings |
C.introduce a new kind of hostel |
D.prove people can sleep on a plane |

With leatherbacks threatened with extinction, Playa Grande’s turtle museum was abandoned (抛弃)three years ago and now sits among a sea of weeds. And the beachside ticket office for turtle tours was washed away by a high tide in September. “We do not promote that as a turtle tourism destination any more because we realize there are far too few turtles to please,” said Alvaro Fonseca, a park ranger.(管理员)
Even before scientists found temperatures going up over the past decade, sea turtles were threatened by beach development, drift net fishing and Costa Ricans’ interest in eating turtle eggs. But climate change may cause the most serious harm to an animal that has lived in the Pacific for 150 million years.
Sea turtles are sensitive to numerous effects of warming. They feed on reefs, which are dying in hotter seas. They lay eggs on beaches that are being covered by rising seas and more violent waves.
More uniquely(独特地), their gender is determined not by genes but by the egg’s temperature during development. Small rises in beach temperatures can result in all-female populations, obviously problematic for survival. If the sand around the eggs hits 30 degrees Celsius, the gender balance shifts to female; at about 32 degrees they are all female. Above 34, you get boiled eggs.
On some nesting beaches, scientists are artificially cooling nests with shade or irrigation and trying to protect broader areas of coastal property from development to ensure that turtles have a place to nest as the seas rise.

B.Tourists have lost interest in watching turtles. | |
C.There are only very few turtles now. | D.The turtle museum was destroyed by a high tide. |

C.are protecting turtles’ nests | D.are going rid of sea weeds |
A.introduce a special kind of sea turtle | B.explain the mystery of turtles’ eggs |

D.attract more visitors to a sea turtle museum |
