问题描述：
He was often listened ______ in the next room.A.sing B.sung C.to sing D.to to sing
而我选C为什么不对啊?
答
listened to在这里是作为一个词组存在的。
答
个人感觉D答案不太对，是不是应该是 to singing
He was often listened to singing in the next room.
他经常被听到在隔壁唱歌。(被听到的时候，肯定是正在唱歌，用进行时态）
答
注意这里的被动语态.很多时候做选择题要善于将句子还原 你就能更容易找到答案.
把这里的被动还原：people often listened to him to sing in the next room.
所以改成被动就变成：he was often listened to to sing in the next room
答
listen to 是一个词组 可以理解为一个单词 动词后面连接动词当然要用介词连接所以选D
