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.
it was so quiet in the classroom that a needle—-————to drop onto the floor
