turf最基础的意思，是指"（铺草坪用的）草皮块"，——
【释义】n. 草皮；（铺草坪用的）草皮块
牛津：[UC] short grass and the surface layer of soil that is held together by its roots; a piece of this that has been cut from the ground and is used especially for making lawns
思维发散一下，自家的草皮，通常是在房屋的外沿，圈出来的区域，就是自己的“地盘”、“势力范围”，这是turf的第二个用法。
【释义】（自己的）地盘，势力范围
牛津：sb's ~( informal ) ( especially NAmE ) the place where sb lives and/or works, especially when they think of it as their own
【例句】
He feels more confident on home turf. 他在主场感到更有信心。
那turf是地盘，turf war自然可以表示为了争夺地盘的战争，也就是——
【释义】（地盘、势力范围等的）争夺战；地盘之争
牛津：a violent disagreement between two groups of people about who should control a particular area, activity, or business
【例句】a vicious turf war between rival gangs of drug dealers 对立贩毒团伙之间的猛烈火并
【BEC真题原句】
Such turf wars make a mockery of companies' effort to present a single face to the customer. (参考翻译：这样的地盘之争使公司向客户呈现单一面孔的努力成为笑柄。）（出处：美森密卷BEC-Higher，H147 Part2 D)
保持好奇心，每日，每月，每年，以求寸进。
