How does it happen that children learn their mother tongue SO well?When we pare them
With adults learning a foreign language，we often find this interesting fact．A little child without
knowledge or experience often succeeds in a plete mastery of the language．A grown—up person with fully developed mental powers，in most cases，may end up with a faulty and inexact corflllland．What accounts for tllis difference?
Despite other explanations。tlle real answer in my opinion hes partly in the child himself，partly in the  behaviour of the people around him．In the first place，the time of learning the mother tongue  in the most favorable of all，namely，the first years of hfe．A child hears it spoken from morning till night and，what is more important，always in its genuine form，with the right pronunciation，rightIntonation，right use of words and right structure．He drinksin all the words and expressions which e  to him in a hsh．ever—bubbhng spring．There is no resistance：there is perfect assimilation．
Then the child has，as it were，private lessons all the year round，while an adult language—
student has each week a limited number of hours which he generally shares with others．The child
has another advantage：he hears the language in all possible situations，always acpanied by the
right kind of gestures and facial expressions．Here there is nothing unnatural，such as is often found
In  language lessons in schools，when one talks about ice and snow in June or scorching heat in January  And what a child hears is generally what immediately interests him．Again and again，when his attempts at speech a聪successful，his desires are understood and fulfilled．
Finally，though a child’S“teachers”may not have been trained in language teaching，their re-
lations with him are always close and personal．ney take great pains to Inske their lessons easy．
