Passage 12

(2009 浙江 E)

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 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 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 to 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.

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.

2. Watson was angry with Franklin because she ______.

A. took the lead in the competition

B. kept her results from him

C. proved some of his findings wrong

D. shared her data with other scientists

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.

4. What is the writer’s attitude toward Wilkins, Watson and Crick?

A. Disapproving.

B. Respectful.

C. Admiring.

D. Doubtful.

rob of 抢劫

bend v . 弄弯,使屈从,压服

contribute to 归功于,有助于,促成

【疑难长句】

1. But three of these people won the Nobel prize for figuring out what the photo really showed—the shape of DNA.

本句结构比较清晰,won为主句谓语,for figuring out为介词短语充当状语,what引导的从句为figuring out的宾语。win...for...表示“因为……而赢得……”,figure out的意思是“弄清楚,发现”。

(参考译文) 但这些人当中有三位因为发现了照片显示的真正内容,即DNA的形态,而赢得了诺贝尔奖。

2. What she did was to produce X-ray pictures that told Watson and Crick that one of their early models was inside out.

What引导主语从句,第一个that引导定语从句,修饰pictures,第二个that引导宾语从句,充当told的宾语。inside out的意思是“把里外弄反了”,类似的用法还有upside down,即“上下颠倒”。

(参考译文) 她所做的就是制作出X光照片,向沃特森和克里克表明,他们早期的模型有误,把里外弄反了。 3PpwZ/epTNYBtXKYJHtk4G9towaOlFYd2qEWCcvAEjN349sn0EBzbkCPr7SeCtwL
