一位科学家做了一个实验:他让一个身强力壮的工人搬运生铁,一连8小时不让这个工人有片刻的休息。等到下班时,这个工人只搬运了12.5吨的生铁,并且已累得精疲力竭。第二天,他让这个工人做同样的事情,不过他改变了一下方法,即这个工人每搬运26分钟后,他便让这个工人休息34分钟。奇迹发生了,同样8小时这个工人竟然搬运生铁47吨,且疲劳的感觉并不十分明显。有人问科学家是怎样想到要做这一实验的?科学家说自己是因为受到
One scientist did an experiment: He let a capable worker carry pig iron for eight hours without letting the worker take a moment’s break.

Miracles happened, the same 8 hours this worker even handling 47 tons of pig iron, and the feeling of fatigue is not very obvious. Someone asked how scientists think about doing this experiment? Scientists say that because of
