教你个办法,如果你分不清楚就直接加名词.
I used to like music.
这里也可以用
I liked music at that time.
I liked listening to music during that period.
一般like doing表示状态,like to do是一次性的动作。
当表示喜欢某事物,而且以前就喜欢,还可能持续,用like doing
当表示想要,欲做某事,特定时间喜欢做某事用like to do,
“那时”是指具体的某次,应该用 like to do
like doing 是指习惯性的喜欢,指一种爱好。
I liked to listen to music then .
like doing sth. 喜欢做某事
At that time I liked listening to music. / I used to like listening to music.
I liked listenning to music at that time.不加the
