钱博士pre向前+cipit=capit，头+ation动名词后缀→头向前运动→一头栽下→猛地落下⇒沉淀，沉淀物；沉降，降落，降水
词根capit-头来自拉丁语。它和日耳曼单词head头最终都源自原始印欧语词根*kaput-头，辅音k-h相通。pre向前+cipit=capit，头+ation动名词后缀→头向前运动→一头栽下→猛地落下⇒沉淀，沉淀物；沉降，降落，降水。GRE难词记忆precipitation→precipitate v.向前猛冲+ion→急促GRE红宝书precipitate 冲出去掉下去 + tion名词指下降的东西词根记忆pre+cipit头=ation=落在前头=降落,下降近义词 rain雨snow雪hail冰雹haste急速speed速度sleet雨雪hurry匆忙moisture水分rashness轻率rainfall降雨downfall垮台hastiness火急drizzle下毛毛雨hurriedness仓促condensation浓缩impulsiveness冲动impetuousness激烈迅疾
