     Grown-ups are often surprised by how well they remember something they learned as children but

have never practiced ever since. A man who has not had a chance to go swimming for years can still

swim as well as ever when he gets back in the water. He can get on a bicycle after many years and still

ride away. He can play catch and hit a ball as well as his son. A mother who has not thought about the

words for years can teach her daughter the poem that begins "Twinkle, twinkle, little star" or remember

the story of Cinderella or Goldilocks and the Three Bears.

     One explanation is the law of overlearning, which can be stated as follows: Once we have learned

something, additional learning trials increase the length of time we will Remember it

      In childhood we usually continue to practice such skills as swimming, bicycle riding, and

playing baseball long after we have learned them. We continue to listen to and remind

ourselves of words such as "Twinkle, twinkle, little star" and childhood tales such as

     Cinderella and Goldilocks. We not only learn but overlearn.

    The multiplication tables(乘法口诀表)are an exception to the general rule. that we

forget rather quickly the things that we learn in school, because they are another of the things

we overlearn in childhood.

     The law of overleatning explains why crammingJ(突击学习)for an examination, though

it may result in a passing grade, is not a satisfactory way to learn a college 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, on the other hand, is

really necessary for one's future development.
