1.George Ashmore Fitch was born in Soochow,China in 1883,the son of Presbyterian missionaries George F.and Mary McLllan Fitch.After receiving his B.A.from Wooster College in 1906,Fitch attended Union Theological Seminary in New York.He was made a priest in 1909 and returned to work in Shanghai.When the Nanking Massacre occurred,Fitch was one of the witnesses of the crime.He quickly became active in assisting the Internatinal Committen for the Nanking Safety Zone.Fitch's diary of events of Nanking was carried to Shanghai by the first person able to leave the Nanking after its occupation by the Japanese on December 13,1937.As Fitch has written,"My story created a sensation in Shanghai,for it was the first news of what had happened in the capital since its evacuation,and it was copied and mimeographed and widely distributed there."Fitch's Nanking diary has been published previously but the version of his diary available in the Yale collection differs slightly from the well-publicized version,so excerpts from it have been included in this volume.In 1938 Fitch traveled throughout the United States giving talks about the Nanking Massacre and showing films to document it.He returned to work first in China and then in Korea and China's Taiwan until his retirement in 1961. 问题：Fitch's story created a sensation in Shanghai because ( )
