Jem was the product of their first year of marriage; four years later I was born, and two years later our mother died from a sudden heart attack. They said it ran in her family.
杰姆是他们结婚第一年的产物，四年之后我出生了，又过了两年，我们的母亲忽然心脏病发作去世了。人们说这是她家族的遗传。
这是《杀死一只知更鸟》里的一段话，把这段话摘录下来，是为了更好地结合语境理解单词的意思。我们知道 “run”这个单词主要意思是“跑”，与不同的单词组合意思有所不同，但它还有一层意思，是我们平常很少用到和接触到的： If something such as a quality, disease, or skill runs in the family, many people in that family have it.“家族遗传（某种品质、疾病、技能等），家族共有”，例如：
Diabetes appears to run in families.
糖尿病似乎是有家族史的。
