I think there is no easy way to succeed in teaching a new language.

A good memory is a great help. However, it is not much use learning by

heart long lists of words and its meanings. We must learn by using language.

“Learn through practice” is a piece of good advice for those which are

learning a new language. Practice is very important. We must practise to

speaking and writing the language so much as we can. We learn to swim by

getting onto the water and swim. And we learn to speak a new language by

speaking it and not by being telling about it.
