这是同做“标记”讲的时候的不同用法.给你几个例句对比对比吧~
sign：I'll be waiting for you at the entrance of the pub which has a sign painted with a red lobster.
我将在画着红龙虾招牌的酒吧门口等你.（sign侧重具体的标记、记号等）
mark:Command of the mother tongue is the most distinguishing mark of the educated man or woman.
运用本国语言的能力是受过教育的人最明显的标志.(mark侧重的是抽象意义上的“标志”)
signal:Signals are made with flags or lamps.
用旗或灯传递信号.（signal多指“暗号”“信号”等）
board是首先被排除的,因为它没有“标记”这个意思.
sign
sign是标牌的意思，to the Shanghai-Nanjing Express way 是介词短语作定语修饰sign,即：上海-南京高速公路的标牌。
因为sigh是标志原形,这里就因该填原形.
