His brother went away and has never been heard____.from ever
His brother went away and has never been heard____.from ever since ,为什么不能用since then A since then B from ever since C after that time D from then on 说A不和句意
答案B是对的,因为hear from 固定词组‘ 收到……的来信’ 句子意思是:他哥哥走了杳无音信.( 意思是家人从没被收到他的来信) 变被动语态时不要把介词去掉,又如 He takes good care of his younger brother .-> His younger brother is taken good care of by him
