词根col(1)来源于拉丁动词colere "to till耕种", 常见的变体形式cult(colere的过去分词形式cultus), from PIE root *kwel-(1) "revolve, move around; sojourn(旅居), dwell", 注意:
1 This conspicuous success has set the stage for a more audacious target: the complete elimination of extreme poverty by 2030.这个引人瞩目的成就为下一个更加大胆的目标做好了铺垫:到2030年完全消除极端贫困。
