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 Wilkins. 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 photos 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 scholars doubt that Franklin was not only robbed of her life by disease but robbed of credit by her competitors
At Cambridge University in the 1950s, Watson and Click 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 reflection 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 “Franklin 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.

Driving to a store after a busy day at work, I saw a man standing near the store holding a sign that said, “Will work for food.” I knew at that moment that I was going into the store and 36 him something to eat.
As I 37 the car park, I saw in my car mirror a lady come out from a hairdresser’s and 38 the man. I thought she must be going to give him some 39 or something to help him out. In the store I was 40 to get the things I needed and also the chicken dinner and a soda that I wanted to give the man outside. I hurried out to my car and 41 that I was going to be able to hopefully help this man.
When I drove out of the car park, I couldn’t see the 42 . As I turned the corner I saw the man sitting in a 43 area away from the hairdresser’s and still 44 up the sign. I immediately 45 over and gave the man the dinner and soda and said, “ 46 this will get you through today.” He looked at me and said, “Thank you so much!”
As I got back into my car, I looked in the 47 and saw the man swallowing the dinner as if he hadn’t eaten for days.
I was so 48 that I was able to help him and at the same time I was so sad that the woman from the hairdresser’s, 49 , had asked the man to 50 from her shop. It’s sad to say that 51 I live in a small city where homeless is not as 52 as in larger cities, people are uncomfortable with these people in 53 . All they need to do is lend a helping hand 54 and it could make a huge 55 in their lives.

On the first day of the new term, I met my new headmaster at the school gate. “Follow me, please!” he said. He had a quiet, kind voice. He took me into my new classroom and left. In front of me, thirty pairs of eyes looked at me. I knew he had told the students that I was blind. I could almost feel the question behind their eyes: Blind? I felt the answer too: If she’s blind, this should be good! I heard quiet voices in a corner of the classroom. For a moment, I felt afraid. I knew at once that I had to be strong.
“Class,” I said as loudly as I could. “I may be blind. But I am not foolish. Take those naughty smiles off your faces, and stop talking, please!” Of course, I could not see their faces; I just guessed that some of them were smiling. The class were quiet. They were very surprised. I knew that I had done the right thing.
As the days went by, the students had more surprises. I could smell when the children were eating sweets. I could easily hear combs going through hair, students passing messages, and so on. Once I found a girl passing a message to a friend. I took the message to the teachers’ room. A teacher read it to me. On one side it said, “Do you think she can see?” on the other it said, “I think so. She always knows what we’re doing.”
Soon the students stopped being naughty, and started to work hard. Before long, they brought in photos of their families for me to look at; I knew then they were my friends. I also knew they had forgotten that I could not see.
