car=car 車；to run跑來源於拉丁文carrus/currere,"car/to run".車上的貨物->cargo;用車搬運->carry。而單詞career
，vocation，occupation，job都指“工作”。區別是：car+-er 原意是“車走的跑道”，沿著特定
軌道一直走下去，不會改變。所以career指長期或終身的，需特殊技能的工作。vocation中字根voc
，指“呼喚的聲音，召喚”，這份工作是上天的召喚，你特別適合，有天分。occupation來源於
occupy，占據你時間的工作，指為了謀生而規律地工作。job指普通工作，學生打工叫part-time
job。
