hear sb. do sth.
听见某人做某事 用原型
hear sb. doing sth.
听见某人正在做某事 用ing形式
本句中有often一词 表示经常听见某人做某事 并非听见某人正在做某事 所以用第一种形式
感官动词hear后面的动词可以用原形或-ing形式,本句中有频率副词“often”,只能用原形。
hear 有两个短语
一个是hear sb. doing(具体某一次听到)
一个是hear sb do (经常听到)
(100% 对)
因为有 often “经常”
表示经常性的东西的时候要用动词原型
这里的sing是名词歌声的意思,不是动词唱歌的意思,所以不用ing形式..
hear sb. do 是固定用法.
