  A rccent study of anclent and modern clcphants has come up with the uncxpeclcd conclusion that the african elcphant is dividcd into two disinct(不同的)species

  The discovery was made by researchers at yod and haycard yniwersities when they were examining the genetid relinship between the ancient woolly manmmth and mastodon to modern ckephants ins asoan alepnant a feoan forest elephant and afcican sannna clephant

  Once they obfantcd DNA sequences{序列}from two fossils{化石},mammothd and mastodons the team comparcd them with dna form ,modcrn eleohants they found to their amazement that modern forest and sabanna elephants are as distinct from cach other as asian elephants and manmoths he scientists used detailed genetic anatysis to proce that the african savanna clelhants hace been distinct species for several million years the divcrgonce of the ttwo species took place around the time of the of the dicergcncc of asian clephants and woolly mammoths this result amazed all the scienitsts

  There has long been debate in the scientific community that the two might be separespecies but this is the most convincing scientinfic evidence so far that they are anded difforent species

  Preci many naluralists believed that afrjcan savanna elephants and airican forest were two plpulations of the same apecies despite the clcphants signigice\ant sizw differences the sac\vanna elelphant has an average shouldcr height of 3.5metres while the forest slsphant has an average shouldcr height of 2.5metres the sacanna laphant welghs belween six anp secedn tons roughly double the weight of the forest elephant but the fact that they look so different does not neccssarily mean they are different species howecer the prooflay in the analysis of th DNA

  Alfred roca allisant professor in the dcoamment of animal scienccs at the unicerstiu of said “wu now nave to reat the forest and savanna elephants at two diffcrcnt units for consrrbation pucpooses since 1950 all african ele[hants are two cery distinctice animals the forest ele[hant shoule become a bigger prioity(优先)for conscrvation puruose”

According to the dictionary definition of “create”,ordinary people are creative every day. To create means”to bring into being, to cause to exist”---something each of us does daily.

  We are creative whenever we look at or think about something in a new way. First this involves an awareness of our surroundings. It means using all of our sense to become aware of our world. This nmay be as simple as being aware of colour and texture, as well as taste, when we plan a meal. Above all, it is the ability to notice things that others might miss.

  A second part of creativity is an ability to see realationships among things. If we believe the expression,” There is nothing new under the sun, ” the creativity is remaking or recombining the old in new ways. For example, we might do this by finding a more effective way is the camera lenses and filters to create an unusual photograph. A third part of creativity is the courage and drive to make use of our new ideas, to apply them to achieve some new results,.To think up a new concept is one thing; to put idea to work is another.

The Peales were a famous family of American artists. Charles Willson Peale is best remembered for his portraits of leading figures of the American Revolution. He painted portraits of Franklin and Jefferson and over a dozen of George Washington. His life-size portrait of his sons Raphaelle and Titian was so realistic that George Washington reportedly once tipped his hat to the figures in the picture.
Charles Willson Peale gave up painting in his middle age and devoted his life to the Peale museum, which he founded in Philadelphia. The world’s first popular museum of art and natural science mainly covered paintings by Peale and his family as well as displays of animals in their natural settings. Peale found the animals himself and found a method to make the exhibits more lifelike. The museum’s most popular display was the skeleton (骷髅) of a huge, extinct(灭绝的)elephant, which Peale unearthed on a New York farm in 1801.
Three of Peale’s seventeen children were also famous artists. Paphaelle Peale often painted still lives of flowers, fruit, and cheese. His brother Rembrandt studied under his father and painted portraits of many noted people, including one of George Washington. Another brother, Rubens Peale, painted mostly landscapes and portraits.
James Peale, the brother of Charles Willson Peale, specialized in miniatures (小画像). His daughter Sarah Miriam Peale was probably the first professional female portrait painter in America.

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  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.
【小题1】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.
【小题2】Watson was angry with Franklin because she     .

A.took the lead in the competitionB.kept her results from him
C.proved some of his findings wrongD.shared her data with other scientists
【小题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 DNA.
C. Her name was forgotten after her death.
D. Her contribution was unknown to the public.
【小题4】What is the writer’s attitude toward Wilkins, Watson and Crick?
A.Disapproving.B.Respectful.C. Admiring.D.Doubtful.
