一个冬季的早晨开始下雪,且以恒定的速度不停地下.一台扫雪机从上午8点开始在公路上扫雪,到9点前进了2km,到10点前进了3km.假定扫雪机每个小时扫去积雪的体积为常数,问何时开始下雪

Some people ought to defend the workaholic.These people are unjustly accused, abused, and defamed -- often termed sick or morbid or on the border of pathology. About 30% of American business and commerce is carried on the shoulders of workaholics. The ratio might exist in art and science too.Workaholics are the achievers, the excelers. There is a national conspiracy against excellence and undue admiration of commonness and mediocrity. It is as if we are against those who make uncommon sacrifices because they enjoy doing something.Some famous psychologists say that the workaholic has an inferiority complex which leads to overcompensation. This is certainly not the case. Inferiority, or low esteem, describes laziness more accurately than it describes dedication.We do not seem to realize that very little excellence is achieved by living a well-balanced life. Edison, Ford, Einstein, Freud all had single-minded devotion to work whereby they sacrificed many things, including family and friendship. The accusation is made that workaholics bear guilt by not being good parents or spouses. But guilt can exist in the balanced life also. Think how many "normal" people and middle-ages who have never done anything well -- they are going to settle for less than what they could have become. According to the author, one can hardly achieve excellence unless one().
