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  1  swim
as well as ever when he gets back in the water. He can get on a bicycle after several decades and still  2 
away. A mother who has not  3  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 law of overlearning, which can be stated as follows:  4  we have learned something,
additional learning increases the  5  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  6  ourselves of poems such as "Twinkle, twinkle, little star" and
childhood tales such as Cinderella or Snow White. We not only learn but  7  .
The law of overlearning explains why cramming (突击学习) for an examination,  8  it may result in a
passing grade, is not a  9  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
overlearning; 10 , is usually a good investment toward the future.
