It has often been said that there's no better teacher than experience. So how does a student of English
learn the language through experience? Obviously,to "experience" English, you'll have to use it as often as
possible. That is why more and more teachers use role plays, dramas and field trips to teach English. What
you see, hear and feel will more likely stick in your mind than what you read in a book.
    Should you have the opportunity to take part in a school drama one day,you will probably try to memorize
your lines to perfection. If you are anything of an actor,you will probably say your lines with emotion. In
other words,you may "experience" the use of the language as it is really used in everyday life. So if I were
you, I would let experience be the teacher.
