像talk,learn等一些词,有时会有talk(learn) sth.,还会有talk(learn) about sth.这两种有什么区别?

像talk,learn等一些词,有时会有talk(learn) sth.,还会有talk(learn) about sth.这两种有什么区别?
像click,doubleclick等词都是及物或不及物动词,为什么点击(双击)它是click(doubleclick) on it?而不是click (doubleclick)it?
尽量快些,

talk 不及物,一般用talk about sth.learn 及物,大多用learn sth.learn about sth.是非专业认真去学,比如学英语是认真用心的,因要考试,与饭碗有关,要learn English,而学煮面条,学吹口哨,就可以learn about sth.
