    優(yōu)質(zhì)解答
    B was to be heard
    be heard to drop 應(yīng)該沒有問題吧?
    hear sth/sb.do 的被動語態(tài).
    could be heard to drop 也是對的.
    但沒有,
    be to do 是表示"注定,能夠"的意思
    與be heard to drop結(jié)合就是B了
    was to be heard to drop .
    太靜,針掉地下都沒聽到.
    C 是用的虛擬,本能聽到卻沒聽到,意思錯了,
    D 一定,意思不好,說的是能不能的問題,或許真有人就沒聽到.
    我來回答
