SECTION B ENGLISH TO CHINESEDirections: Translate the following text into Chinese.It was not hot that day, but many were sweltering.Julius Streicher, the Jew - baiter of Nuremberg, was there. This sadist and pornographer, whom I had once seen striding through the streets of the old town brandishing a whip, seemed to have Wilted. A bald, decrepit- looking old man, he sat perspiring profusely, glaring at the .judges and convincing himself--so a guard later told me--that they were all Jew. There was Fritz Sauckel, the boss of slave labor in the Third Reich, his narrow little slit eyes giving him a porcine appearance. He seemed nervous, swaying to and fro. Next to him was Boldur von Schacht, the first Hitler Youth Leader and later Gauleiter of Vienna, more American by birth than German and looking like a country college boy who has been kicked out of school for some folly. There was Wahher Funk, the shifty - eyed nonentity who had succeeded Schacht. And there was Dr. Schacht himself, who had spent the last months of the Third Reich as a prisoner of his once revered Fuehrer in a concentration camp, fearing execution any day, and who now bristled with indignation that the Allies should try him as a war criminal. Franz yon Papen, more responsible than any other individual in Germany for Hitler’s coming to power, had been rounded up and made a defendant. He seemed much aged, but the look of the old fox, who had escaped from so many tight fixes, was still imprinted on his wizened face. There were still others who once had their days were nervous, fearing to be put to death some day.
