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(历史学家) 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(学者)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.

1.What is the text mainly about?

2.Watson was angry with Franklin because she .

We were on the way from Hutchinson to Chicago for a short spring break. For many years I had wanted to take my family on the train. We all had been to Chicago four years ago, and the kids loved it. Chicago is one of my favorite cities, too, so the thought struck me again last fall to ride the train to Chicago. Of course, flying would have been faster. But I don’t think flying is easier, especially these days, with all the security and waiting in lines at airports.

Though we were tired in the middle of the night, the kids got on the train with the exhilaration of this adventure. “We’re moving,” my son William shouted happily with big eyes as the train began to pull away from the Hutchinson station.

I removed my shoes and lay down to try to finish my night’s sleep. The sleeper car would have better enabled that, but the ordinary train seats were not too bad. An airline flight is a harder experience for me: not enough room, two hours of pain with my knees almost touching my mouth. On the train I could almost outstretch all of my 6-foot-2-plus body in the generous legroom.

The journey didn’t feel at all as long as it was. We all found the train ride a joy. The car ride would have felt every minute of 13 hours. But on the train you are free to walk around, sit in the observation carriage for a while and enjoy the scenery out the windows, have a nice meal in the dining car, read a book, or play a board game.

In short, the train is all about enjoying the trip, which isn’t something I do so much when traveling by airline or by car, when the trip seems more of a mission (任务) to get there than an experience to enjoy along the way.

Chicago offers much to do for a family. This time, getting there was half the fun.

1.We can learn from the first paragraph that _____.

A. the kids love the train journey

B. it was the first time that the kids were taken on the train

C. the author didn’t enjoy the long train journey

D. Chicago is one of the kid’s favorite cities

2.What does the underlined word “exhilaration” in Paragraph 2 probably mean?

A. Tiredness. B. Relaxation.

C. Excitement. D. Worry.

3.In the third paragraph, an airline flight experience is mentioned to show _____.

A. a train ride is more comfortable

B. a train ride is too long

C. an airline flight is miserable

D. an airline flight is easier

4.Which of the following words best describes the whole family’s feeling about the train journey?

A. Moved. B. Nervous.

C. Disappointed. D. Delighted.
