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 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.

   passage

When I met him, I had a lot of anger inside of me. I’ve lived my whole life in Spanish Harlem, but in my neighborhood, there are shoot-ups all the time. I know kids who have been shot or beaten up. I have friends who ended up in prison. I could have ended up that way, too, but Mr. Clark wouldn’t let that happen.

Mr. Clark worked long hours, making sure I did my work. My grades rose. In fact, the scores of our whole class rose. One day, he took our class to see The Phantom of the Opera, and it was the first time some kids had ever been out of Harlem. Before the show, he treated us to dinner at a restaurant and taught us not to talk with our mouths full. We did not want to let him down

Mr. Clark was selected as Disney’s 2000 Teacher of the Year. He said he would draw three names out of a hat; those students would go with him to Los Angeles to get the award. But when the time came to draw names, Mr. Clark said, “You’re all going.”   

On graduation day, there were a lot of tears. We didn’t want his class to end. In 2001, he moved to Atlanta, but he always kept in touch. He started giving lectures about education, and wrote a bestselling book based on his classroom rules, The Essential 55. In 2003,

Mr. Clark took some of us on a trip to South Africa to deliver school supplies and visit the orphanages(孤儿院). It was the most amazing experience of my life. It’s now my dream to one day start a group of women’s clubs, helping people from all backgrounds.

Without Mr. Clark, the writer         .

A. might have been put into prison

B. might not have won the prize

C. might have joined a women’s club

D. might not have moved to Atlanta

The Essential 55 is_____________

A. a show                                          B. a speech

C. a classroom rule                             D. a book

How many students’ names were finally drawn out of a hat by Mr. Clark?

A. None                B. Three                C. Fifty-five.         D. All.

What can we learn in the short reading?

A. It was in Harlem that we saw The Phantom of the Opera for the first time.

B. Mr. Clark taught us not to talk with our mouths full, and we did.

C. Mr. Clark was selected as Disney’s 2000 Teacher of the Year in Los Angeles.

D. In 2003, Mr. Clark moved to Atlanta, and he always kept in touch with us.

In the passage, the writer intends to tell us that         .

A. Mr. Clark went to South Africa because he liked travelling

B. Mr. Clark helped to set up a group of women’s clubs

C. a good teacher can help raise his or her students’ scores

D. a good teacher has a good influence on his or her students

There are many kinds of friends. Some are always    36   you, but don't understand you. Some say only a few words to you, but understand you. Many people will step in your life, but only   37  friends leave footprints.

　　I shall always recall (回忆) the autumn and the girl with the  38  . She will always bring back the friendship between us. I know she will always be my best friend.

　　It was the golden season. I could see the yellow leaves   39  on the cool  40 . In such a season, I liked walking alone in the leaves,  41   to the sound of them.

　　Autumn is a  42   season and life is uninteresting. The free days always get me   43  . But one day, the sound of a violin   44   into my ears like a stream (小溪) flowing in the mountains. I was so surprised that I jumped to see what it was. A young girl, standing in the wind, was  45   in playing her violin.

　　I had  46  seen her before. The music was so nice that I listened quietly. Lost in the music, I didn't know that I had been   47  there for so long but my existence (存在) did not seem to disturb her.

　　Leaves were still falling. Every day she played the violin in the corner of the building  48  I went downstairs to watch her performance. I was the only listener. The autumn seemed no longer lonely and life became   49  .  50  we didn't know each other, I thought we were already good friends. I believe she also loved me.

Autumn was nearly over. One day, when I was listening carefully, the sound suddenly

   51  . To my astonishment (惊讶), the girl came over to me.

　　“You must like violin.” she said.

　　“Yes. And you play very well. Why did you stop?” I asked.

　　Suddenly, a   52  expression appeared on her face and I could feel something unusual.

　　“I came here to see my grandmother, but now I must leave. I once played very badly. It was your listening every day that   53  me.” she said.

　　“In fact, it was your playing   54  gave me a meaningful autumn,” I answered, “Let's be friends.”

　　The girl smiled, and so did I.

I never heard her play again in my life. I no longer went downstairs to listen like before. Only thick leaves were left behind. But I will always remember the fine figure (身影) of the girl. She is like a   55 —so short, so bright, like a shooting star giving off so much light that it makes the autumn beautiful.
