答案B是對的,因為hear from 固定詞組‘ 收到……的來信’
句子意思是：他哥哥走了杳無音信.（ 意思是家人從沒被收到他的來信）
變被動語態(tài)時不要把介詞去掉,又如
He takes good care of his younger brother .-> His younger brother is taken good care of by him
His brother went away and has never been heard____.from ever since ,為什么不能用since then
His brother went away and has never been heard____.from ever since ,為什么不能用since then
A since then B from ever since C after that time D from then on 說A不和句意
A since then B from ever since C after that time D from then on 說A不和句意
