今天我們要學的詞是 bluff.

bluff 的意思是虛張聲勢、唬人。 U.S. President Donald Trump appears to be calling North Korea's bluff on its end-of-year deadline for nuclear negotiations, prompting some analysts to worry that Pyongyang's threats should be taken more seriously. 美國總統特朗普似乎對朝鮮提出限于年底前進行核談判這個虛張聲勢的要求不買賬，這讓一些分析人士擔心，是否應更為慎重地對待平壤的威脅。

Before Mexico agreed to take "strong measures" to stop migrants heading toward the U.S., President Donald Trump said he was not bluffing about imposing 5% tariffs on Mexican imports if it did not help. 在墨西哥同意采取“強有力的措施”阻止移民前往美國之前，特朗普總統表示他所說的如果墨西哥不提供幫助，就會對其進口產品征收5％的關稅并不是嚇唬人。
