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?
A.The disagreements among DNA researchers.
B.The unfair treatment of Franklin.
C.The process of discovering DN
D.The race between two teams of scientists.
(2)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
(3)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
C.Her name was forgotten after her death.
D.Her contribution was unknown to the public.
(4)What is the writer's attitude toward Wilkins, Watson and Crick?
A.Disapproving.
B.Respectful.
C. Admiring.
D.Doubtful.

【答案】

(3)D
(4)A
【解析】本文讲述了主人公Franklin对发现DNA的贡献,但却始终不为人所知的一系列事情。

(1)B主旨大意题。本文讲述了主人公Franklin的一系列事情,第一自然段作者提到"The fourth, ----- was left out ",最后一段也提到"She contributed more than any other player to solving the structure of DNA.She must be considered a co-discoverer,"由此看出命运对她的不公,选B。

(2)C细节理解题。由"What she did was ------- And she was not shy about saying so",可知选C。

(3)D细节理解题。从文中看出作者多次提及Franklin对发现DNA的贡献,但却始终不为人所知,由此理解dark,所以称为"Dark Lady of DNA",选D。

(4)A观点态度题。由倒数第二段"As Franklin's competitors, Wilkins, -----from the solution." 可推出作者是不赞成,选A。

When other nine-year-old kids were playing games, she was working at a petrol station. When other teens were studying or going out, she struggled to find a place to sleep on the street. But she overcame these terrible setbacks to win a highly competitive scholarship and gain entry to Harvard University. And her amazing story has inspired a movie, “ Homeless to Harvard: The Liz Murray Story”, shown in late April.
Liz Murray,a 22-year-old American girl, has been writing a real-life story of willpower and determination. Liz grew up in the shadow of two drug-addicted parents. There was never enough food or warm clothes in the house. Liz was the only member who had a job. Her mother had AIDS and died when Liz was just 15 years old. The effect of that loss became a turning point in her life. Connecting the environment in which she had grown up with how her mother had died, she decided to do something about it.
Liz went back to school. She threw herself into her studies, never telling her teachers that she was homeless. At night, she lived on the streets. “ What drove me to live on had something to do with understanding, by understanding that there was a whole other way of being. I had only experienced a small part of the society,” she wrote in her book Breaking Night.
She admitted that she used envy to drive herself on. She used the benefits that come easily to others such as a safe living environment, to encourage herself that “next to nothing could hold me down”. She finished high school in just two years and won a full scholarship to study at Harvard University. But Liz decided to leave her top university a couple of months earlier this year in order to take care of her father, who has also developed AIDS. “I love my parents so much. They are drug addicts. But I never forget that they loved me all the time.”
Liz wants moviegoers to come away with the idea that changing your life is “as simple as making a decision”.
(1)The main idea of the passage is __________ .
A.how Liz managed to enter Harvard University

【题目】阅读理解。
Many facts suggest that children are overweight (超重的) and the situation is getting worse, according to the doctors. I feel there are a number of reasons for this.
Some people blame the fact that we are surrounded by shops selling unhealthy, fatty foods, such as fried chicken and ice cream, at low prices. This has turned out a whole generation of grown-ups who seldom cook a meal for themselves. If there were fewer of these restaurants, then probably children would buy less take-away food.
There is another argument that blames parents for allowing their children to become overweight. I agree with this, because good eating habits begin early in life, long before children start to visit fast food shops. If children are given fried chicken and chocolate rather than healthy food, or are always allowed to choose what they eat, they will go for sweet and salty foods every time, and this will carry on throughout their lives.
There is a third reason for this situation. Children these days take very little exercise. They do not walk to school. When they get home, they sit in front of the television or their computers and play computer games. Not only is this an unhealthy pastime (消遣), it also gives them time to eat more unhealthy food. What they need is to go outside and play active games or sports.
The above are the main reasons for this problem, and therefore we have to encourage young people to be more active, as well as steering them away from fast food shops and bad eating habits.
(1)According to the text, what kind of children may eat more unhealthy food?
A.Those who often take exercise.
B.Those who often watch television.
C.Those who often have meals at home.
D.Those who often walk to school.
(2)What is one reason that children become overweight?
A.Children can' t choose what to eat.
B.Children are too busy to go out and play.
C.Children's parents often cook meals for them.
D.There are too many fast food shops around.
(3)What does the underlined word “steering” in the last sentence most probably mean?
A.Forcing.
B.Guiding.
C.Driving.
D.Moving.
(4)What' s the main purpose of the text?
A.To tell a story.
B.To provide facts.
C.To give advice.
D.To compare opinions.
