Fur peple in England back in 1953, stared at Pht 51,It wasn’t much—a picture shwing a black X. But three f these peple wn the Nbel Prize fr figuring ut what the pht really shwed –the shape f DNA The discvery brught fame and frtune t scientists James Watsn, Francis Crick, and Maurice Wilkins. The furth, the ne wh actually made the picture, was left ut.
Her name was Rsalind Franklin.”She shuld have been up there,” says histrian Mary Bwden.” If her phts hadn’t been there, the thers culdn’t have cme up with the structure.” One reasn Franklin was missing was that she had died f cancer fur years befre the Nbel decisin. But nw schlars dubt that Franklin was nt nly rbbed f her life by disease but rbbed f credit by her cmpetitrs
At Cambridge University in the 1950s, Watsn and Click tried t make mdels by cutting up shapes f DNA’s parts and then putting them tgether. In the meantime, at King’s Cllege in Lndn, Franklin and Wilkins shne X-rays at the mlecule(分子). The rays prduced patterns reflectin the shape.
But Wilkins and Franklin’s relatinship was a lt rckier than the celebrated teamwrk f Watsn and Crick, Wilkins thught Franklin was hired t be his assistant .But the cllege actually emplyed her t take ver the DNA prject.
What she did was prduce X-ray pictures that tld Watsn and Crick that ne f their early mdels was inside ut. And she was nt shy abut saying s. That angered Watsn, wh attacked her in return, “Mere inspectin suggested that she wuld nt easily bend. Clearly she had t t g r be put in her place.”
As Franklin’s cmpetitrs, Wilkins, Watsn and Crick had much t gain by cutting her ut f the little grup f researchers, says histrian Pnina Abir-Am. In 1962 at the Nbel Prize awarding ceremny, Wilkins thanked 13 clleagues by name befre he mentined Franklin, Watsn wrte his bk laughing at her. Crick wrte in 1974 that “Franklin was nly tw steps away frm the slutin.”
N, Franklin was the slutin. “She cntributed mre than any ther player t slving the structure f DNA . She must be cnsidered a c-discverer,” Abir-Am says. This was backed up by Aarn Klug, wh wrked with Franklin and later wn a Nbel Prize himself. Once described as the “Dark Lady f DNA”, Franklin is finally cming int the light.
57. What is the text mainly abut?
A. The disagreements amng DNA researchers. B. The unfair treatment f Franklin.
C. The prcess f discvering DNA. D. The race between tw teams f scientists.

A. tk the lead in the cmpetitin B. kept her results frm him
C. prved sme f his findings wrng D. shared her data with ther scientists

C. Her name was frgtten after her death. D. Her cntributin was unknwn t the public.
