You play to win,and the game has little meaning unless you do your utmost to win.为什么这么写

你打球（任何运动）是为了要赢的,但是如果你不尽力去赢,这个比赛就没有意义了.the game has little meaning unless you do your utmost to win.意思我知道这是什么写法是条件状语从句。The game has little meaning unless you do your utmost to win.==The game has little meaning if you don't do your utmost to win.The game has little meaning 是主句，unless you do your utmost to win是条件句 希望对你有启发，如对你有帮助，请记得及时采纳
