7．[1]Adults are often astonished 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．
[2]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．
[3]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．
[4]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．
[5]The law of overlearning explains why cramming（突击学习）for an examination，though it mayresult in/lead to/contribute to/bring/bring about 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．

3．The computer makes doing schoolwork easier for me than it was for my mom and dad．For example，when writing book reports and stories，I use Microsoft Word instead of a pen and paper．That way，after my teacher checks my work，I can go back and make revisions without having to rewrite the whole thing．And Microsoft Word has a spell check!I use it all the time．
For English class，we are reading The Outsiders by S．E．Hinton．As pre-reading homework，my teacher asked us to research teenage groups on the Internet．I tried Google，Encarta，and Yahoo first，and finally found an article on Time．com．
For geography homework on the United States，I used Encarta to learn about the Mississippi River．I needed to find out how deep the river is，how its widths and depths are different，what states it runs through，and what kinds of fish live in it．I used the information to show how the geography of a country influences its economy．For example，the river's trade paths，the number of fish caught in it and the tourists it attracts directly affect Southerners'jobs and incomes．
I never go to the library to do research．It takes too much time．Since I live in New York City and both my parents work，getting to the library isn't always easy．For a big task or research project，I used to stay at the library to read，or sign out whatever books or magazines I needed．Now being able to find the information in my own living room makes everything a lot simpler．Online dictionaries and encyclopedias （百科全书） also save time．
Sometimes，I think the computer spoils my generation because it is so easy---at least physically．But computers are not like television，which does the thinking for you．You still have to use your mind．I prefer using a computer，easy，fun，and fast．
