你好~我也是一个学汉语的留学生~ 在hsk考试用的语法上解释（跟中国人想法有一点不一样，可是考试的时候我说的对） 我学汉语学了三个月（你以前学过三个月的汉语，现在不学。） 我学韩语学了三个月了（你学了三个月汉语，到现在一直学） 这是在hsk语法书上发现的

我学汉语学了三个月了表示你现在还在学习 正在进行时 而我学汉语学了三个月表示你之前的行为 过去式

我学汉语学了三个月了 = I've been learning Chinese for three years now. 我学汉语学了三个月 = I learned Chinese for three years (when I was at high school). 1. 学了 = completed action 了 (I did it) 2. 三个月了 = new situation 了 (It has been) A very good text book will explain all that.

“我学汉语学了三个月了”means “I have studied Chinese for three months” “我学汉语学了三个月”means "I studied Chinese for three months"

Haha!! That's my impression too... But the below answers really help! Thanks everyone! ;-)
