常考释义
For instance, infant mortalitywas high and life expectancy much shorter than today, home tutoring was commonin the families of the nobility and wealthy, bullying and corporal punishmentwere common at the best independent schools and, for the most part, the casesstudied were members of the privileged classes.
例如，从前的婴儿死亡率比现在要高，人均寿命比现今的要短，只有有钱的贵族家庭才有家教，校园暴力和体罚事件在当时最好的私立学校也屡见不鲜，而大部分的研究数据的针对对象都只是特权阶级。
