（3）在验证机械能守恒定律的实验中，质量为m的重锤从高处由静止开始落下，重锤上拖着的纸带通过打点计时器打出一系列的点，对纸带上的点的痕迹进行测量，就可验证机械能守恒定律。
1如图所示，选取纸带上打出的连续五个点A、B、C、D、E，测出A点距起始点O的距离为SO，点A、C间的距离为S1，点C、E间的距离为S2，使用的交流电的频率为f，则C点的速度为 ，打点计时器在打C点时重锤的动能为 ，打点计时器在打O点和C点的这段时间内重锤的重力势能减少量为 。利用这个装置也可以测量重锤下落的加速度，则加速度a的表达式为a= 。
②在验证机械能守恒定律的实验中发现，重锤减小的重力势能总是约大于重锤增加的动能，其原因主要是因为在重锤带着纸带下落过程中存在着阻力作用，若已知当地重力加速的值为g，用第1小题给出的已知量表示重锤在下落过程中受到的平均阻力大小为F= 。

Don’t worry,You just hove to put your finger near a special scanner,. The grocery bill will be taken out of your bank accout
We are not joking，
A new system that scans customers’ fingerprints and subtracts（除去）the grocery bill from their bank accouts has taken supermarkets in Germany by storm. Stores, school canteens and even bars are picking it up.
The Edeka suwww.ks5u.compermarket chain is the first retail(零售)business in Germany to use the new system . “Almost a quarter of our customers pay with their fingers,”said an employee at the headquarters.
Edeka has tried the system at 70 of its supermarkets．It says it will introduce it at 200 others because customers like it
“At first we thought that only the young who really keep up with the latest technology would be interested，but we were wrong,”said Stenfan Sewoester from IT Werke.
“Almost two-thirds of the people who use the system are 40 and older，”he said．
IT Werke.,a computer company, is
one of the pioneers of fingerprint payment software in
To sign up for the service，customers must have their fingerprints taken and 1eave，her addresses and banking details with the shop．The shop then takes the cost of goods directly out of the customer’s bank account。
“It is especially a good thing for elderly people。Now they do not have to remember their pin(密码)to pay with their bank cards，or to look around for their glasses cash.” Sewoester sald． ．

Blunt comes to
Blunt,34，took an unusual path to stardom．His father was a soldier and so was his grandfather。
“The only music he heard growing up was‘Happy Birthday’and‘Silent Night”. His father considered all music，even classical，to be unnecessary noise，”reads Biunt’s official website．
Even though Bhmt did not want to join the military(军队)，he eventually followed his father’s wishes，and served as a soldier in Kosovo on peacekeeping duty。
“Like any parents，mine wanted me to have a secure job with a regular wage and career prospects，”Blunt said．“And the one job my father knew of，that he’d had experience of himself，was the army，so he could help me in that direction．’’
Blunt eventually became a Captain．One of his final duties in the army before retirement was carrying the coffin(棺材)at the funeral of the Queen Mother of England in 2002．
But Blunt couldn’t escape his love for music．So，after leaving the British Army he moved to Los Angeles and worked on his first album．While in LA，Blunt lived with the actress Carrie
Fisher，who played the lead female role in the Start,Wars movies．He recorded his song，Goodbye My Love,in her bathroom，where she kept a piano．
Blunt took his new albura back to England where it was not very successful．But he kept performing and eventually his song，You’re Beautiful，became a number one hit．

South Korea，the country that created the world’s first cloned dog，plans to use duplicated(复制)dogs to sniff out(闻出)drugs and explosives(炸药)．
The Korean Customs Service uncovered last Thursday seven cloned Labrador retrievers(拉布拉多猎狗)．They are trained near lncbeon International Airport，west ot Seoul。The dogs were born five to six months ago after being separately cloned from a skilled drug-sniffing dog．Officials said using cloned dogs could help reduce costs ,due to the difficulties in finding dogs that are qualified for the jobs．
The cloning work was carried out by a team of Seoul National University scientists?In 2005 they successfully created the world’s first known dog clone，an Afghan hound(猎犬)namad，Snuppy．The team is led by Professor Lee Byeong-chun
The seven new cloned male dogs are all healthy．For now，they share the same name：“Toppy”。一a combination of the words“tomorrow”and“puppy”．
“They are active and excel in accepting the training，”said Kim Nak―seung，a trainer at
the Customs Service’s dog training center．
In February，aII seven dogs passed a behavior test aimed at finding whether they ate geneticaliy qualified to work as sninffing dogs． Only 10 percent to 15 percent of naturally born dogs typically pass the test．
If the cloned dogs succeed in other tests for physical strength，concentration and sniffing ability，they wi|ll be put to work by July next year at airports and harbors accros South Korea．according to the training center． Officials say the cloned dogs could also save money?
“We came up with the idea of dog cloning after thinking about how we can have a superior
breed(品种)at a cheaper cost，”said Hur Yong―suk，head of tlie training center?
Normally，only about three out of every 10 naturally born dogs it trains--at a cost of abotlt $ 40，140 each―ends up qualitying for the job．

The Invention of Hugo Cabret，by Brian Selzniek，is a novel like no other．There are pages of exciting events and then suddenly。wait!A picture with tiny details，then a big piecture that takes up the whole page--and the next page，and the next page，and the next！ The pictures are actually telling the story．It’s like a book and a movie all in one．
I recently had the opportunity to talk with Selzniek about his unique novel．1 wanted to know just how he came up with the concept of writing a novel that reads like a picture book．
“Because the book is so much about movies and the history of cinema，I also wanted to figure
out how to make a book that is also 1ike a movie，”said Selznlek．
Writing and illustrating(作插图)the book was a long and hard process，Selznick said． One of the challenges was figuring not what the story was really about and what happened to the main character，Hugo．Selzniek also had to figure out how to make the narrative and the pictures work together to tell the story．
Selznick has actually spent most of his career as an illustrator and really considers him。 self more of an artist than a writer．‘‘I’ve always drawn，ever since 1 was a little kid．1 was
encourged to draw，and so that’s what I feel most comfortable with，”he said．
He still enjoys many of the things he liked as a kid．That’s why it's not so hard for him to think about what kids would like to read in a book．In fact，sometimes he feels like a kid himself．
But sometimes figuring out what was going to happen in the story was not easy，he told me?He had no idea what the story was going to be about when he started writing．He didn’t know if it was going to be sad，adventurous，or exciting．Selznick turned to friends for advice on the book．For now，Selznick doesn’t plan on writing a sequel(续篇)to the book，but he warns，“You can never say never．”
53．The Invention of Hugo Cabret is
A．a novel on which a movie has been based
B．a novel only using pictures explaining series of events
C．a book which tells children how to draw pictures
D?a book packed with pictures―a combination of words and drawings
54．It can be inferred that the text is
A．an introduction to an unusual novel
B．a summary record of an interview
C．a biography of the novelist Brian Selznick
D．an ad persuading kids into buying the novel
55?According to Paragraph 4，working with pictures is for Selznick．
A．difficult B．embarrassing C．natural D．troublesome
56?What does Selzniek mean by saying“You can nevef say never”?
A?It’s hard to say whether he will continue writing the book．
B。It is such a difficult book that he won’t continue it．
C．He will never give up writing a sequel to the book．
D He will never write a novel like The Invention of Hugo Cabret．

You are only as old as you feel，it is said．But soon scientists will be able to calculate
your real“physiological(生理的)age”．
Researchers studying genes believe they can now ten exact physiological age by looking at a number of clues in DNA．They don’t have to ask people how they feel or look at their appearance．
The breakthrough could solve the mystery of why some 70-year-olds function at the level of those in their 50s，while others become frail(虚弱的)sooner than you would think?
The researchers made the breakthrough by finding the“biomarkers”of aging in tiny worms(虫子)．
The worms they studied had all average lifespan(寿命)of three weeks．Like humans’some remain lively much longer than other similarly-aged worms，while others show signs of premature aging?
By genetieally profiling(基因识别)104 different worms at various ages，the researchers found a group of genes that are involved in the aging process?
“This is a first step;our results were not perfect，but we were able to predict the ages of the animals 70 percent of the time，which is far better than anything that has been done before．”said
Sireon Melov。the lead researcher at Buck Institute for Age Research in california。
Now they want to extend their Stlidles to mice and eventually humans．
“l am confident that at some point there will be a non-subjective(主观的)method of determining how old someone is with a high level of confidence，”said Melov．
The speed at which people age depends on a number of things including genetic inheritanee(遗传)，lifestyle and mental health．
Determining chronological(按时间顺序的)age in both worms and humans is easy-count forward from birth．But determing physiological age has remained subjective－based on how someone looks or functions．
The findings have special meanings for age research in humans．Examining biomarker。Over time would provide a scient．fic basis for anti―aging medicines．The technology would also provide a means of determining whether a person is aging faster or slower than people would normally think．
57．The passage mainly talks about
A。the new finding of gene studying
B．the relationship between genes and the age
C．the breakthrough in mental health
D．biomarkers of ageing,in tiny worms
