hear sb do sth和hear sb doing sth.
hear sb do sth表示“聽到某人做了某事”,hear sb doing sth.表示“聽到某人正在做某事”,一些感觀動詞如hear,see,feel,watch等后面既可以接賓語+do sth,也可接賓語+動詞-ing形式構成復合賓語.根據(jù)情景及句意的需要許多時候只能用一種,但有時兩者都可用而意義沒多大區(qū)別.
例如：
1、He once heard someone talk about it/ talking about it.
他有一次聽到有人談到過這件事/正在談論這件事.
2、I like to hear you play the music.
我喜歡聽你彈這首曲子.（不用playing）
3、He heard someone playing his Sonata in F.
他聽到有人正彈奏他的F調奏鳴曲.
4、I didn’t see you come in.我沒見到你進來.
5、But I didn’t feel the train moving.
但我沒有感到火車在移動.
