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 scholar doubt that Franklin was not only robbed of her life by disease but robbed of credit by her competitions.

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 erlationship 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 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 “Franklins 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.

58. 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

59. 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.

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

The rumors had been spreading for months but it still came as a shock when the hospital would be closing. It had served this poor neighborhood for nearly 100 years but it would close because of the health care crisis.
The day after the announcement co-workers found out that pretzels(椒鹽餅干) had been eliminated. Soft pretzels are the lifeblood of this city. So losing access to soft pretzels is no small matter.
I said, “I only have $6. I’m not sure how many pretzels I need. You see, I work at a hospital and it’s closing and they stopped selling pretzels.” The man’s smile disappeared. “What hospital?” “Oh, Northeastern Hospital.”
The guy looked deeply shocked. “I used to sell medical supplies and that was one of my hospitals.” Then he turned around and grabbed a box of 25 pretzels and slid them across the counter.
I was surprised by his generosity and started to reach for my wallet, “Oh I can pay. Please let me …” The guy smiled, “Just tell them Joe Sullivan said to do something nice for someone else.”
And so that day everyone in medical records was treated to a soft pretzel. Word spread fast as people came asking, “Is it really true?” It was as if I’d carried in a box of gold. It mattered to them that a stranger cared.

Does this sound familiar? It’s 3:00 am and you’re still awake and staring at the clock. You can’t sleep , and you’ve already tried all the familiar tricks – taken a warm bath , drunk a glass of heated milk ,tried counting sheep, and read a book –all with no success.

Lack of sleep can hurt your quality of life in so many ways. Short temper, impatience, poor decision-making, and mood swings are common among those with sleeping problems.

Other sleep aids may seem like a quick fix, but it turns out that there are many disadvantages of these drugs. For one thing, they may require expensive, time-consuming trips to your physician. They may also be habit-forming or have unpleasant side effects like dizziness( 眩暈) dry mouth, and next-day sleepiness. Plus , they become less effective over time.

So what is the best sleep aid available on the market today? The answer is Somnapure , a product that represents nature and science coming together.

B．introduce a kind of medicine to help sleep better
