It's best to learn them by practicing using/hearing them in a conversation. That way you can learn them and know how they are used properly. (I know that is how I learned common Chinese phrases.

Learning a new language is no different. Learn English slowly. Start with one or two common sayings, then learn three or four, and more! Write the English words in a notebook and practice each day. Here are some good websites: http://www.languageguide.org/english http://www.omniglot.com/language/phrases/mandarin.php http://www.chinese-tools.com/phrasebook The links go Mandarin to English, but you can go English to Mandarin. Also, listen to lots of American music (slow and fast music) and watch American movies. Good luck! Ask me more questions if you need help.

actually, most the idioms and phrases have their origin from the Bible or some myths, so just have a clear understanding of these stories and naturally you will remeber those idioms, and you do not learn by rote~~~ it is ok for reciting dozens of phrases, but there are thousands of idioms out there, hehe have a nice day~~~
