Here are a few websites about slang. The firs ones list hundreds of slang terms. Others are slang dictionaries. One of them (Urban Dictionary) is a Wiki project, which means that users contribute to the definitions, and it can have very offensive language. http://www.manythings.org/slang/ http://www.slangsite.com/ http://www.urbandictionary.com/ http://www.peakenglish.com/slang/slangSearch.jsp http://www.alphadictionary.com/slang/ http://www.slang-dictionary.org/

I once recommended the following websites to a friend: http://www.everythingenglish.net/App_UI/InCommon/Pages.aspx?Id=2764 http://www.learnamericanenglishonline.com/American_Slang/American_Slang_A.html http://www.rootsweb.ancestry.com/~genepool/amerispeak.html http://www.world-english.org/slang.html http://www.mylanguageexchange.com/Learn/Native-American.asp http://learnenglish4freeonline.com/index.php?name=Pictures&id=31&cat_id=17&parent=17 http://www.manythings.org/slang/

我是通过看美剧学的。电影也不错，但是往往台词偏少，背景音乐太多。 找一部自己感兴趣的美剧，肥皂剧也行，不过要有一点心理承受能力，有些美剧太瞎掰了。 用最最笨的方法，就是看或者听N遍！！！是N遍哟，反正我就是这么干的。可以在潜意识当中进行模仿。 现在天天开着电脑放波士顿法律，推荐你不妨试试看。 以上是我的个人意见。

Hello Hisun, Beside making good use of the previously recommended websites, you could also mingle with native English speakers, you will find many of them using slang during their speech. You might find those slang expressions weird or incomprehensible for you ,so don't hesitate to ask what they mean. By chatting all the same with natives they do use slang during online conversations and you could learn many of them through your chats. Watching English and American movies will help you as well catch a lot of those expressions. Good luck:)
