*76.I heard this song _____ by my students in the next room.

heard sb doing sth.听见某人做某事.
this song,只能被唱,by也是被动句的标志,所以用被动时态,be动词加动词的过去分词形式,sing的过去分词是sung,
强调做了某事,be用being.
所以是being sung

D.being sung
hear sb do/doing sth是固定搭配，所以可排除C，接着根据题意可得是‘这首歌被我的学生们’唱，故选D——被动语态

首先 hear sb. doing sth.
排除A、C
然后，歌曲是被唱男，所以应该是被动形式，排除B
选D
我用的是手机，如果有疑问发消息问我，如果满意就采纳我叭。~O(∩_∩)O
