After graduating，Franklin worked first in Cambridge and later in the British Coal Utilisation Research Association.During the war，she also served for a period as an Air Raid Warden.After the war，Franklin travelled to Paris to work where she learnt X­ray diffraction techniques (衍射技术)．In 1951，Franklin returned to England.She used her knowledge of X­rays to improve equipment at King's College.This actually enabled her team to produce very meaningful photos of DNA.When James Watson，a scientist working on his own DNA structure in Cambridge，saw these photos，he said，“My jaw (下巴) fell open，and my heartbeat began to race.” In a 1953 edition of Nature，James Watson and Francis Crick published a paper on the structure of DNA，which had been informed by Franklin's photos.In the same edition，Franklin published her data on DNA.Franklin was more careful about publishing a more accurate (精确的) theory of DNA structure.She wished to see more experimental evidence.However，Watson and Crick were more confident and they announced in Feb.，1953 that they had “found the secret of life.” Franklin's data and photos were very important in their DNA theory. In 1953，Franklin left for Birkbeck College，where she found a greater freedom.However，increasing ill health caused her to retire from work.Franklin died of cancer in 1958. 【语篇解读】　本文是一篇说明文。文章主要讲述了英国化学家Rosalind Franklin
