Adults are often surprised by how well they remember something they learned as children but have never practised in the meantime. A man who has not had an opportunity to go swimming for years can ___21___ swim as well as ever when he gets back in the water. He can get on a bicycle after several decades and still    22    away. A mother who has not    23   the words for years can teach her daughter the poem that begins "Twinkle, twinkle, little star" or recite the story of Cinderella or Snow White.

　　One explanation is the    24     of over learning, which can be stated as following: Once we have learned something, additional learning increases the    25    of time we will remember it.

　　In childhood, we usually continue to practise such skills as swimming, bicycle riding long after we have learned them. We continue to listen to and    26    ourselves of poems such as "Twinkle, twinkle, little star" and childhood tales such as Cinderella or Snow White. We not only learn but  __27   .

　　The law of over learning explains why cramming (突击学习) for an examination, though it may result in a(an)    28     grade, is not a    29    way to learn a school course. By cramming, a student may learn the subject well enough to get by on the examination, but he is likely soon to forget almost everything he learned. A little over learning,    30   , is usually a good investment toward the future.

We find that bright children are rarely held back by mixed-ability teaching. On the contrary, both their knowledge and experience are enriched. We feel that there are many disadvantages in streaming（把…按能力分班）pupils. It does not take into account the fact that children develop at different rates. It can have a bad effect on both the bright and the not-so-bright child. After all, it can be quite discouraging to be at the bottom of the top grade!

　　Besides, it is rather unreal to grade people just according to their intellectual (智力的) abilities. This is only one aspect of their total personality. We are concerned to develop the abilities of all our pupils to the full, not just their academic ability. We also value personal qualities and social skills, and we find that mixed-ability teaching contributes to all these aspects of learning.

　　In our classrooms, we work in various ways. The pupils often work in groups: this gives them the opportunity to learn to co-operate, to share, and to develop leadership skills. They also learn how to cope with personal problems as well as how to think, to make decisions, to analyze and evaluate, and to communicate effectively. The pupils learn from each other as well as from the teacher.

　　Sometimes the pupils work in pairs; sometimes they work on individual tasks and assignments, and they can do this at their own speed. They also have some library, and we teach them the skills they need in order to do this effectively. And expect our pupils to do their best, not their least, and we give them every encouragement to attain this goal.
