Question

frontier n.边界；边境；尖端；边缘 (1) 我们在边界那儿被赶了回来。(2) 边界从北部山地一直延伸到南部海岸。(3) 边境上一切安静。(4) 这个新的边境事件可能导致战争。(5) 我们少数人在该专业尖端领域面临困难。(6) 医学知识的新领域正随着时间向前推进。(7) 他来自遥远的边疆。 The noun frontier has several meanings. It can refer to the wilderness at the edge of a settled area (picture covered wagons pushing westward) or it can mean a field of study that has not yet been explored (picture genetically engineering pet dinosaurs). Deriving from "the front line of an army," a frontier can be thought of as an offensive line in a battle — always pushing forward, trying to conquer new territory.
