How to Be a Winner

 Sir Steven Redgrave

 Winner of 5 Olympic Gold Medals

 “In 1997 I was found to have developed diabetes(糖尿病). Believing my career(职业生涯) was over, I felt extremely low. Then one of the specialists said there was to no reason why I should stop training and competing. That was it -the encouragement I needed. I could still be a winner if I believed in myself. I am not saying that it isn’t difficult sometimes. But I wanted to prove to myself that I wasn't finished yet. Nothing is to stand in my way.”

 Karen Pickering

 Swimming World Champion

 “I swim 4 hours a day, 6 days a week. I manage that sort of workload by putting it on top of my diary. This is the key to success-you can’t follow a career in any field without being well-organized. List what you believe you can achieve. Trust yourself, write down your goals for the day, however small they are, and you’ll be a step closer to achieving them.”

 Kirsten Best

 Poet & Writer

“When things are getting hard, a voice inside my head tells me that I can’t achieve something. Then, there are other distractions, such as family or hobbies. The key is to concentrate. When I feel tense, it helps a lot to repeat words such as ‘calm’, ‘peace’ or ‘focus’, either out loud or silently in my mind. It makes me feel more in control and increases my confidence. This is a habit that can become second nature quite easily and is a powerful psychological(心理的) tool”

Passage 1

(09·浙江E篇)

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.

57. 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.
