D
　　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.

大人经常惊讶于他们如何记住的东西,他们的孩子知道但从不自从.一个人没有机会去游泳年仍然可以游泳以及曾当他回到水里.他可以骑上自行车经过多年,仍然走.他可以打球和击球以及他的儿子.一个母亲谁也没有想过的话可以教导她的女儿诗开头“一闪,一闪,小星星”或记得灰姑娘的故事或金发姑娘和三只熊.
