Four people in England, back in 1953, stared at photo 51. it wasn’t much –a picture showing a black X. But three of these people won the Nobel prize for figuring out what the photo really showed—the shape of DNA. The discovery brought fame and fortune to scientists James Watson, Francis crick, and Maurice Willkins. The fourth, the one who actually made the picture, was left out.
Her name was Rosalind Franklin. “She should have been up there,” says historian Mary Bowden. ”if her photo hadn’t been there, the others couldn’t have come up with the structure.” one reason Franklin was missing was that she had died of cancer four years before the Nobel decision. But now scholar doubt that Franklin was not only robbed of her life by disease but robbed of credit by her competitions.
At Cambridge University in the 1950s, Watson and Crick tried to make models by cutting up shapes of DNA’s parts and then putting them together. In the meantime, at king’s college in London, Franklin and Wilkins shone X-rays at the molecule(分子). The rays produced patterns reflecting the shape.
But Wilkins and Franklin’s relationship was a lot rockier than the celebrated teamwork of Watson and Crick. Wilkins thought Franklin was hired to be his assistant. But the college actually employed her to take over the DNA. project.
What she did was produce X-ray pictures that told Watson and Crick that one of their early models was inside out. And she was not shy about saying so. That angered Watson, who attacked her in return,” Mere inspection suggested that she would not easily bend. Clearly she had to go or be put in her place.
As Franklin’s competitors, Wilkins, Watson and Crick had much to gain by cutting her out of the little group of researchers, says historian Pnina Abir-Am. In 1962 at the Nobel prize awarding ceremony, Wilkins thanked 13 colleagues by name before he mentioned Franklin. Watson wrote his book laughing at her. Crick wrote in 1974 that “Franklins was only two steps away from the solution.”
No, Franklin was the solution.” She contributed more than any other player to solving the structure of DNA. She must be considered a co-discoverer,” Abir-Am says. This was backed up by Aaron Klug, who worked with Franklin and later won a Nobel Prize himself. Once described as the “Dark Lady of DNA”, Franklin is finally coming into the light.
1.What is the text mainly about?

The wedding between Prince William and Kate Middleton on April 29 has focused the world’s camera lenses(镜头)on the UK.
In Britain, there is a constant debate about the relevance of the royal family to modern British society. However, Windsor (the family name of the British Royal Family) and Middleton have been seen to represent a more modern, forward-looking nation.
Nigel Baker, the British ambassador to Bolivia, believes that the royal wedding is “about modern Britain”. “The estimated 2 billion spectators across the world will see that Britain is one of the most culturally and ethnically diverse nations in the world, home to 270 nationalities speaking 300 different languages, founded on tolerance and respect for difference,” wrote Baker on his blog.
According to Baker, the wedding could help viewers to see “why Britain is one of the most dynamic and creative countries in the world”: The television on which most people watched the event was invented by John Logie Baird, a Briton, and the World Wide Web that broadcast the event to millions more was invented by another Briton, Tim Berners-Lee.
The guests who attended the wedding ceremony gave more than a few clues as to the nature of modern Britain. David and Victoria Beckham represent Britain’s obsession(着迷)with football and celebrity.
Leaders from different religious backgrounds supported Baker’s comments on the multicultural nature of modern British society.
Before the wedding, David Elliott, arts director of the British Council China, agreed that the wedding would be a showcase for modern Britain: “I think, and hope, that it (modern British influence) would be values like openness, multiculturalism, creativity, sense of humor and the traditional British sense of fair play,” he said.
Furthermore, events such as the Olympics in London in 2012 may also increase people’s sense of Britishness.
According to a poll published in Daily Telegraph, more than a third of people in the UK admitted they felt “very British” when watching the Olympics.

D. Britons are obsessed with football due to the influence of David Beckham.
3.Why is the inventor of the World Wide Web mentioned?

Photos that you might have found down the back of your sofa are now big business!
In 2005,the American artist Richard Prince’s photograph of a photograph,Untitled (Cowboy),was sold for $1 248 000.
Prince is certainly not the only contemporary artist to have worked with so-called “found photographs”—a loose term given to everything from discarded(丢弃的)prints discovered in a junk shop to old advertisements or amateur photographs from a stranger’s family album.The German artist Joachim Schmid,who believes “basically everything is worth looking at”,has gathered discarded photographs,postcards and newspaper images since 1982.In his on-going project,Archiv,he groups photographs of family life according to themes:people with dogs;teams;new cars;dinner with the family;and so on.
Like Schmid,the editors of several self-published art magazines also champion(捍卫)found photographs.One of them,called simply Found,was born one snowy night in Chicago,when Davy Rothbard returned to his car to find under his wiper(雨刷)an angry note intended for someone else:“Why’s your car HERE at HER place?”The note became the starting point for Rothbard’s addictive publication,which features found photographs sent in by readers,such as a poster discovered in your drawer.
The whole found-photograph phenomenon has raised some questions.Perhaps one of the most difficult is:can these images really be considered as art?And,if so,whose art?Yet found photographs produced by artists,such as Richard Prince,may raise endless possibilities.What was the cowboy in Prince’s Untitled doing?Was he riding his horse hurriedly to meet someone?Or how did Prince create this photograph?It’s anyone’s guess.In addition,as we imagine the back-story to the people in the found photographs artists,like Schmid,have collated(整理),we also turn toward our own photographic albums.Why is memory so important to us?Why do we all seek to freeze in time the faces of our children,our parents,our lovers,and ourselves?Will they mean anything to anyone after we’ve gone?
In the absence of established facts,the vast collections of found photographs give our minds an opportunity to wander freely.That,above all,is why they are so fascinating.
