托福听力official10 The word “evolved” in the passage is closest in meaning to 答案解析

evolve: 进化，演化。A是分裂；B是延长；C是发展；D是是销声匿迹。所以C的develop正确。对应原文：Whitewares produced in Hebei and Henan provinces from the seventh to the tenth centuries evolved into the highly prized porcelains of the Song dynasty (AD. 960-1279), long regarded as one of the high points in the history of China's ceramic industry. 原文说七到十世纪的白瓷怎么样成了宋代的很好的瓷，无论从时间上还是后面说的highly prized都证明后面的比前面的好，所以应该是变好的意思，A分开B延伸D消失都没有变好之意。
