今天我们要学的词是 ambiguity。
ambiguity 的意思是不明确，模棱两可的。Ambiguity over what the Brexit deal might be has pushed investors to protect themselves aginst – or make money from - further falls in the pound. 对于英国脱欧可能达成什么样协议的不确定性让投资者们准备为英镑进一步下跌做出自我保护，或者从中赚钱。
When U.S. Secretary of Defense Jim Mattis was asked about how the Pentagon would respond to an attack on a satellite, he said he preferred to maintain ambiguity. 当美国国防部长被问到如何应对卫星袭击时，他表示更希望对此保持模糊性
