But i think watching mother tongue DVD’s with english subtitles gives a better grip over english as we r accoustomed to speak our mother tongue . when we speak english we do tend to put our ideas and if we couldn’t find a word with a simillar meaning to the word we use in our mother tongue then we pause and think’s of a word closely related to it and this thing makes us to speak like freak. So watch DVD’d and these inturn help us in building grammer and makes us comfortable and confident with english .
