“V+过” is to say an experience u had in the past，so it emphasize the experience thing. “了” is to say the thing the behavior happened in the past or is finished. V+了 is declare the verb is finished，sometime in the past. sentence+了 is more like to tell something u have done or have been doing up to now. it can be finished by now or can stil continue. 我学了三个月汉语。（2013年1月~2013年3月 not studying anymore now） 我汉语学（了）三个月了。（2014年3月~今天 minght keep studying or might finish today） wish my explain can help~O(∩_∩)O~

多谢。I actually wrote 学 rather than 学习 the first time round but then changed it!! Good to know the difference now though.

It might help to think of 学习 as verb-object. When there is an object like 汉语 or 中文, you don't need 习. When there isn't an object, 学习 sounds better than just 学.
