1.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 65years,smokers had significantly more fine wrinkling than nonsmokers.Similar findings were seen in participants aged 45to 65years,"Helfrich"s team added in their report.
The researchers tested 82people,smokers and nonsmokers,taking pictures of the inner right arms. They ranged,in age from 22to 91and 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,.

72.When your skin is exposed to sunlight long,it-becomes all of the following butA.
A.flexible  B.coarse      C.rough     D.discolored
73.How wrinkled a person's skin is doesn't relate toB.
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

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
75.The main purpose of the passage is toC.
A.inform people about the result of the study
B.advise people how to protect skin
C.warn people not to smoke again
D.introduce a new way of avoid skin aging.

18.I left home to support my sister in her efforts to present a music festival.She lives on the other side of the world,and I went to visit her,not wanting to leave,and feeling like I was leaving home against my will.But I wanted to show her my support,because she is my only sister.
So I boarded the plane in mid-August,and hated the long flight.I had left my husband of 2years,alone,in our old New Orleans house.
I was all set and ready to perform for my sister for the music festival,on Sunday morning,when I received a call from Chicago.The hurricane was predicted to hit our city,and many had already escaped.But my husband chose to stay behind.He could not get a call to me on the other side of the world,but he could call his cousin in Chicago.He gave his cousin a message for me,that he would be just fine,and not to worry.
As the day wore on,I finally took the stage in front of hundreds of Europeans,and I realized,thanks to CNN,that New Orleans was under water.
I performed,hoping that my husband would survive.And I performed perfectly.The audience stood and cheered for me.I rushed off the stage and straight to the TV.I saw the street sign near my home,of Humanity Street,but nothing below it,except water.
In the days that followed,I found out that my house,my car,my clothes,my furniture,everything that I'd left behind was gone…but not my husband.He survived by riding on the back bumper(保险杠) of a VW bus,holding on to the overhead luggage shelf,in the pouring rain,down the highway from New Orleans,half-way to Baton Rouge.The rest of the journey was a long walk.But he survived.
By the first week of September,I flew back to the Baton Rouge airport,and hugged my husband.Since then,our relationship has grown deeper,we have completely repaired our house,bought a new car,bought new furniture and new clothes and joined an inspirational,spirit-filled church.

9.Legos (乐高玩具)
    Architecture lovers in Washington do not have to travel far to see some of the world's must famous building.Architect Adam Reed Tucker has rearrested fifteen of them using Lego bricks.The exhibit is called"LEGO Architecture:Towering Ambition."It is at the National Building Museum in Washington until early September.
  Lego bricks are small,colorful plastic blocks.They can be snapped together to make any number of objects.They are popular with children of all ages around the world.
  Adam Reed Tucker calls himself an"architectural artist."
  He was a professional architect for ten years.After the terrorist attacks against the United States in two thousand one he decided to do something different.He wanted to express his feelings for the form of the skyscraper while deepening his understanding of architecture,engineering and construction.He chose to use something that most people used as children and could relate to.
  The buildings in the exhibit include the World Trade Center in New York that was destroyed in the terrorist attacks; the Gateway Arch in Saint Louis,Missouri; the famous house called Fallingwater in Pennsylvania,designed by Frank Lloyd Wright; and the Burj Khalifa in Dubai,the tallest building in the world.Tucker used more than four hundred fifty thousand Legos to make his version which is more than five meters tall.
  Tucker does all his work by hand,using only pictures of the buildings.He does not use any computers or drawings to plan his buildings.While the exhibit is going on,Tucker will be working on his latest work,the White House where the American president lives.Visitors can watch him create the famous building brick by brick.
  Anne Bennett visited the Building Museum with her two grandchildren,Dylan and Daisy.She used the Lego exhibit to teach her grandchildren about famous buildings.
"My favorite is probably that tall building because it's made out of Legos.It's really cool because it looks like there's individual little rooms."Said Daisy.
What Daisy was talking about is the Willis Tower,formerly known as the Sears Tower in Chicago,Illinois.The real building is over four hundred forty meters tall.Tucker's model stands six meters tall.
  After walking through Tucker's models,visitors can create their own works at the building station.They can make houses,office buildings,stores or factories.They can then place their models on a large map of a city.As more visitors come,the Lego city will grow.
  To many people,Legos might seem like toys for kids.But Adam Reed Tucker proves that the only limit to what the toy can do is a person's imagination.

6.Walking with long steps on purpose,Barack Obama appears to have arrived to visit an elementary school he attended as a boy.But wait.It's not real Obama.The US president is back in Washington DC.
So who is this guy?He's Ilham Anas,34,a teen-magazine photographer who has taken advantage of his striking resemblance to Obama and turned it into his own brand of celebrity and wealth.
Since his sister told him in 2007that he looked like the then-presidential candidate,Ana's face and big smile have been seen on Southeast Asian TV and the Internet,appearing in the advertisements of medicine and other products.He has also shown up on his nation's television-talk show.Anas'resemblance to the president has turned his life around 180degrees.He's even written an autobiography Because of Obama.
Anas is the first to admit that he's an impostor(冒牌货).But he'll also tell you that he's in incredible demand."I've got so much work I can't handle it all,"he said.
But when his sister first mentioned the resemblance,he dismissed it.Then a colleague at the magazine asked him to pose as Obama in front of a US flag.He also refused."I'm a photographer,not an object for the camera,"he said.
As soon as he accepted the idea,his career took off.The married father of two children is rarely home these days.Recently a group of reporters followed him on a tour of the elementary school Obama once attended.Anas sat in the classroom where the president studied.He spoke a few lines in English.The moment he opened his mouth,however,the differences became apparent."Obama is a baritone(男中音),"Anas said."I'm not.I sound like a little boy."He is also shorter than the president.But he makes up for that by practising Obama's typical actions.Before public appearances,he spends hours in front of the mirror posing,gesturing,flashing that smile.
Anas said he hasn't changed his appearance much for the role.He wears his hair just like he did in high school.But he did shape his eyebrows to look more like those of the president.
He used to dislike looking into the mirror because of his average appearance.Now he no longer considers himself as an average guy,but a superstar.
Now,he hopes that Obama will win a second term in the White House.‘‘The longer he's in office,the longer my fame will last,"he said.
