单选题 The ______ of gifted children into accelerated classes will start next week according to their academic performance.
A. segregation B. specification C. spectrum D. subscription

【正确答案】 A
【答案解析】[解析] 本句空格处意为将有天分的儿童分到提高班，segregation的意思是“分开，分离”，与句意相符。specification“详述，规范”，spectrum“光谱，频谱”，subscription“捐献，订阅，同意”都不正确。
