Yeah, same as my need.... And my suggestion is.... create environment such as listen music, watch movie, news and etc in English. And...choose one DVD movie that you like it and play in your native language at the first time. Then re-run in your native language and English Subtitle at second time. And re-run in English and subtitle in your native language at third time and the last one is only English language. Test it and let me know..... !!! It's great!!

Hi...!!! I try to explain but I'm not good in English :) But If you still don't understand..... I'll try to explain more... ;-p ไม่ means NO.... It uses for decline or disagree or deny in the sentense. ใช่ไหม means Right? (question word) It uses when you tell something and need someone to confirm the thing that you tell is correct...An answer is yes or no รึเปล่า means Or not? or correct or what ? (question word) It looks like the ใช่ไหม but an answer normally express their opinion...Ex... The world is flat or what?.. Oh..no... It's circle like an orange. หรือ means OR.......to choose one....this or that...., right or wrong, correct or what..etc. I hope you can understand my answer....!!! ;-D
