53. In ancient Egypt, the pharaoh(法老) treated the poor message runner like a prince when he arrived at the palace, if he brought good news. However, if the exhausted runner had the misfortune to bring the pharaoh unhappy news, his head was cut off. Shades of that spirit spread over today’s conversations. Once a friend and I packed up some peanut butter and sandwiches for an outing. As we walked light-heartedly out the door, picnic basket in hand, a smiling neighbor looked up at the sky and said, “Oh boy, bad day for a picnic. The weatherman says it’s going to rain.” I wanted to strike him on the race with the peanut butter and sandwiches. Not for his stupid weather report, for his smile. Several months ago I was racing to catch a bus. As I breathlessly put my handful of cash across the Greyhound counter, the sales agent said with a broad smile, “Oh that bus left rive minutes ago.” Dreams of head-cutting! It’s not the news that makes someone angry. It’s the unsympathetic attitude with which it’s delivered. Everyone must give bad mews from time to time, and winning professionals do it with the proper attitude. A doctor advising a patient that she needs an operation dose it in a caring way A boss informing an employee he didn’t get the job takes on a sympathetic tone. Big winners know, when delivering any bad news, they should share the feeling of the receiver. Unfortunately, many people are not aware of this. When you’re tired from a long flight, has a hotel clerk cheerfully said that your room isn’t ready ye? When you had your heart set on the toast beef, has your waiter merrily told you that he just served the last piece? It makes you as traveler or diner want to land your fist right on their unsympathetic faces. Had my neighbor told me of the upcoming rainstorm with sympathy, I would have appreciated his warning. Had the Greyhound salesclerk sympathetically informed me that my bus had already left, I probably would have said, “Oh, that‘s all right. I’ll catch the next one.” Big winners, when they bear bad news, deliver bombs with the emotion the bombarded (被轰炸的) person is sure to have . In Paragraph 1, the writer tells the story of the pharaoh to . (A) make a comparison (B) introduce a topic (C) describe a scene (D) offer an argument

55. From “Dreams of head-cutting!”(Paragraph 3), we learn that the writer . (A) was mad at the sales agent. (B) was reminded of the cruel pharaoh (C) wished that the sales agent would have had dreams. (D) dreamed of cutting the sales agent’s head that night.

56. What is the main idea of the text? (A) Delivering bad news properly is important in communication. (B) Helping others sincerely is the key to business success. (C) Receiving bad news requires great courage. (D) Learning ancient traditions can be useful.

57.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 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 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 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. 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 DN(A) (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
