A good memory is a great help in learning a language. Everybody learns his own language by remembering what he hears when he is a small child, and some children—like boys and girls who live abroad(国外）with their parents—seem to learn two languages almost as easily as one. In school it is not easy to learn a second language because the pupils have so little time for it, and they are busy with other subjects, too.
Our mind is rather like a camera, but it takes photos not only of what we see but of what we feel, hear, smell and taste. When we take a real photo with a camera, there is much to do before the photo is finished and ready to show to our friends. In the same way, there is much work to be done before we can keep a picture forever in our mind. Memory is the diary that we all carry about with us.
