13．US scientists have performed an important reversal（逆转） of the ageing process in animal studies．They used a chemical to rejuvenate（使年轻） muscle in mice and said it was the equivalent（等同于） of transforming a 60-year-old's muscle to that of a 20-year-old-but muscle strength did not improve．Their study，in the journal Cell，identified an entirely new mechanism（原理） of ageing and then reversed it．Other researchers said it was an"exciting finding"．
Ageing is considered a one-way street，but now researchers at Harvard Medical School have shown that some aspects can be reversed．Their research focused on a chemical called NAD．Its levels naturally drop in all cells of the body with age．The team showed this damaged the function of the cell's in-built power-stations，leading to lower energy production and ageing．
Experiments showed that increasing NAD levels，by giving mice a chemical which they naturally change into NAD，could reverse the sands of time．One week of youth-medication in two-year-old mice meant their muscles became similar to those of a six-month-old．
Dr Ana Gomes，from the department of genetics at Harvard Medical School，said："We believe this is quite an important finding．"She argues muscle strength may return with a longer course of treatment．However，this could never be a cure-all for ageing．Other aspects such as shortening of telomeres or damage to DNA would not be reversed．
Dr Gomes told the BBC："Ageing is multi-factorial，it's not just one component（成分） we can fix，so it's hard to target the whole thing．I believe there is a lot of cross-talk in cells and energy is very important in a cell and likely to be a very big component of ageing that might cause some of the other things that happen with ageing．"

 2．只允许修改10处．
My father walked into my room to let me know that dinner was ready．It was 6o'clock in a Saturday evening，and I was studying as usually．Suddenly，we hear the horrible screams．Rushing outside，we saw a person who running away and our neighbor，Miss Slade，lay on the ground in front of her garden．His continuous cries made me worried．My father tried talking to her while I went to get some bandage．I did my best to wrap her wounds and slowed the bleeding．When ambulance arrived and took over，we started to relax．The doctor said it was our fast response and the Life Saving class I had taken earlier that year had saved her life．
15．The Mona Lisa，one of the world's most famous paintings，has been recreated with 3，604cups of coffee-and 564pints of milk．The different colors were created by adding no，little or lots of milk to each cup of black coffee．
The recreated Mona Lisa measured 20 feet long and 13 feet wide．It took a team of eight people three hours to complete the work．It was created for The Rocks Aroma Festival in Sydney，Australia，and seen by 130，000people who attended the one-day coffee-lovers event．
Elaine Kelly，one of the organizers from the Sydney Harbor Foreshore Authority，was delighted with the result．She said，"Each coffee cup was filled with varying amounts of milk to create the different shades（色度） of the painting．We wanted to create an element of surprise and a sense of fun in the way we communicated with the public．"
"Once we had the idea of creating an image（像） out of coffee cups we searched for something iconic（有代表性的）to reproduce（复制）．And after some time we chose the most iconic painting in history．The Mona Lisa has been reproduced so many times in so many different mediums but，as far as we know，never out of coffee，"Kelly continued．"Besides，the idea is practical．"
"It was fantastic．It really looked like the famous painting-the Mona Lisa．It was wonderful，"said one visitor．
After much planning it was great to see it coming together so well and the 130，000people who attended the event certainly enjoyed it and were deeply attracted by it，"said Kelly．

12．Every week in China，millions of people will sit in front of their TVs watching teenagers compete for the title Character Hero，which is a Chinese-style spelling bee（拼写大赛）．In this challenge，young competitors must write Chinese characters by hand．To prepare for the competition，the competitors usually spend months studying dictionaries．
Perhaps the show's popularity should not be a surprise．Along with gunpowder and paper，many Chinese people consider the creation of Chinese calligraphy（书法）to be one of their primary contributions to civilization．Unfortunately，all over the country，Chinese people are forgetting how to write their own language without computerized help．Software on smart phones and computers allows users to type in the basic sound of the word using the Latin alphabet．The correct character is chosen from a list．The result？It's possible to recognize characters without remembering how to write them．
But there's still hope for the paint brush．China's Education Ministry wants children to spend more time learning how to write．
In one Beijing primary school we visited，students practice calligraphy every day inside a specially decorated classroom with traditional Chinese paintings hanging on the walls．Soft music plays as a group of six-year-olds dip brush pens into black ink．They look up at the blackboard often to study their teacher's examples before carefully attempting to reproduce those characters on thin rice paper．"If adults can survive without using handwriting，why bother to teach it now？"we ask the calligraphy teacher，Shen Bin．"The ability to write characters is part of Chinese tradition and culture，"she reasons．"Students must learn now so they don't forget when they grow up．"says the teacher．
25．What can we learn about the Character Hero？D
A．It's open to people of all ages and all walks．
B．It's the most-viewed TV programs in China．
C．It aims to spread Chinese culture to the world．
D．It draws great public attention across the country．
26．Why are Chinese people forgetting how to write the characters？D
A．Chinese people don't refer to dictionaries very often．
B．Chinese people no longer use brush pens or practice calligraphy．
C．Chinese people are using the Latin alphabet instead of the characters．
D．Chinese people needn't write by hand as often with the help of technology．
27．According to Shen Bin，being able to write characters by hand isC．
A．necessary for adults to survive in China
B．a requirement made by the Education Ministry
C．helpful to keep Chinese tradition and culture alive
D．an ability to be developed only when you are students
28．Where does this text probably come from？A
A．A news report．
B．A science report．
C．An advertisement．
D．Children's literature．
13．After obtaining a specific college degree，a job applicant can be competitive for ____ unavailable jobs．（　　）
