8：my mother likes listen to music——这句话是否有错。

如果是一次性的用like to do sth.
如果是持续的用like doing sth.
象你这个例子，可能用like listening to music比较适合一些

错
my应该大写

应该改成：My mother likes listening to music.

like doing 表示喜欢做某事~

my mother likes to listen to music 这个对
或 my mother likes listening to music

listen--listening
like doing sth. 喜欢做某事

不对。 likes listening

My mother likes listening to music
or
My mother likes to listen to music
