You have waited 45 minutes for the valuable 10 minutes’ break between classes. But when the bell for the next class rings, you can’t   36   how quickly time has passed.

If you are familiar with this   37  , you’ll know how time flies when you are having fun-and  38   when you are bored. Now scientists have   39   a reason why this is the case.

Scans have shown that patterns of activity in the brain   40   according to how we focus on a task. When we are   41  , we concentrate more on how time is passing. And this makes our brains   42   the clock is ticking more slowly.

In an experiment   43   by a French laboratory, 12 volunteers watched an image   44   

researchers monitored their brain activity.

The volunteers were told to   45   concentrate on how long an image appeared for, then

  46   the color of the image, and thirdly, study both duration and color. The results showed that  47   was more active when the volunteers paid   48   subjects.

It is thought that if the brain is   49   focusing on many aspects of a task, it has to  50  its resources, and pays less attention to the clock.  51 , time passes without us really   52   it, and seems to go quickly. If the brain is not so active, it concentrates its   53   energies on monitoring the passing of time.   54  , time seems to drag.

Next time you feel bored   55  , perhaps you should pay more attention to what the teacher is saying!

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?

A. Disapproving

B. Respectful.

C. Admiring

D. Doubtful
