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 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 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.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.Watson was angry with Franklin because she .

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

Dear Earthmen,
I have enjoyed my stay on your interesting unusual planet. I think I understand the life on earth now and I would like to give you my impressions.
First of all you live in boxes. Every morning you leave your big boxes and get into smaller boxes on wheels. All these small boxes race around and around, and finally stop to rest. You then leave these boxes on wheels and go to very large tall boxes.
After testing all days you get back in your little boxes and return to your big boxes. There you sit and stare at tiny glowing boxes with moving pictures on the front.
Only one thing puzzles me. One day, I went to a football game. A bunch of angry boys fought over a little round ball. Everyone yelled for them to stop but they kept on fighting. They were angry, I suppose, about being cooped up(被关起来)in boxes all day.
Thank you earthmen for this chance to get to know you.
Gratefully,
The man from the Mars(火星)

Every people(民族)uses its own special(特殊的)words to show its ideas and feelings. Some expressions are commonly used for many years. Others are popular for just a short time. One such American expression is“Where’s the beef?”It is used when something is not as good as it is said to be In the early 1980s “Where’s the beef?”was one of the most popular expressions in the United States. It seemed as if everyone was using it at the time.
Beef, of course, is the meat from a cow, and no food is more popular in America than a hamburger(汉堡包)made from beef. In the 1960s a businessman named Ray Kroc began building small restaurants that sold hamburgers at a low price. Kroc called his restaurants“McDonald’s”. Ray Kroc became one of the richest businessmen in America.
Other business people watched his success. Some of them opened their own hamburger restaurants. One company(公司)called“Wendy’s”said its hamburgers were bigger than those sold by McDonald’s or anyone else’s .The Wendy’s Company began to use the expression“Where’s the beef?”to make people know that Wendy’s hamburgers were the biggest. The Wendy’s television advertisement(广告)showed three old women eating hamburgers. The bread that covered the meat was very big, but inside there was only a bit of meat. One of the women said she would not eat a hamburger with such a little piece of beef.“Where’s the beef?”she shouted in a funny way. The advertisement for Wendy’s hamburger restaurants was a success.
