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.
【小题1】What is the text mainly about?
A. The disagreements among DNA researchers.
B. The unfair treatment of Franklin.
C. The process of discovering DNA.
D. The race between two teams of scientists.
【小题2】Watson was angry with Franklin because she     .

A.took the lead in the competitionB.kept her results from him
C.proved some of his findings wrongD.shared her data with other scientists
【小题3】Why is Franklin described as  “Dark Lady of DNA”?
A. She developed pictures in dark labs.
B. She discovered the  black X-the shape of DNA.
C. Her name was forgotten after her death.
D. Her contribution was unknown to the public.
【小题4】What is the writer’s attitude toward Wilkins, Watson and Crick?

B
I am a person who does not like to wait in line. However, I realize anger will get me nowhere. Considering this, I have decided to turn my frustration(沮丧) to productive ends. In short, I am constantly hunting around for what I call “waiting in line books”, especially those that are designed for being read in snippets(文摘), so there is no extended story line to lose track of. Another requirement is that they be small enough to slip neatly into my back pocket.
The other day I went to the supermarket and was surprised to see that the place was crowded with shoppers, but no worries. I parked my cart behind five others and pulled out my vocabulary builder. Within a few seconds I was totally absorbed, and rather than seething at the 15 minutes it took to advance to the cashier, I learned that nankeen is “a yellow cotton cloth”, or, in the plural, “trousers made of it”. The acquisition of new words led me into a place where I would otherwise not have enjoyed myself so much.
Once, at a yard sale, I found two small pocket books titled Sidelights on American History (copyright 1919). The seller approached as I looked through the pages. “You want them?”
“First I need to see if they fit,” I told him. He watched as I slipped Volume 1 into my back pocket. “Perfect. I’ll take them.”
10 minutes later, I was at the carwash, where the waiting line was six vehicles long. Thank goodness for my books! By the time my car was being soaped and power sprayed, I had learned about the Annapolis Convention, the early life of Aaron Bur.
The more the world demands that I wait, the more I learn from my waiting library. In fact, I have become so fond of my “waiting” books that my spirits actually rise when I see a long line I must stand in. It is most likely I would be regarded as a bookish, lonely soul. But little would they realize that I was enjoying the company of those “waiting” books. And just as Disraeli said, “Everything comes if a man will only wait”.
60. When buying a book the writer _____.
A. has his own rules                        B. prefers books of small size
C. chooses books by famous writers            D. has no particular appetite
61. The truth behind the story is that the writer wants to tell us _____.
A. reading is not only important but also practical
B. one is expected to learn to adjust oneself rather than complain
C. reading is the best way to kill time
D. knowledge is power and wisdom is fortune
62. The underlined expression in paragraph 3 “seething at” probably means _____.
A. angry at                   B. delighted at              C. surprised at        D. excited at
63. The sentence in Paragraph 2 “there is no extended story line to lose track of” shows that _____.
A. what the writer reads is not difficult to understand
B. the writer likes to read interesting stories while waiting in line
C. the writer can stop wherever needed with no plot to leave out
D. the writer does not necessarily reach his understanding
