今天我们要学的词是 hindrance. hindrance 的意思是阻力，障碍。The U.S. said it will scale back military exercises with South Korea next year, so the war games are not a hindrance to diplomacy over ending North Korea's nuclear weapons program. 美国表示将在明年缩减与韩国的军事演习，这样军演就不会阻碍为结束朝鲜核武计划而进行的外交努力。One of the touchy issues in Brexit talks is whether Ireland and Northern Ireland will again be separated by a so-called “hard border” or the Irish will be able to move themselves and their goods across the border without hindrance. 英国脱欧谈判中一个棘手的问题是，爱尔兰和北爱尔兰是否会被所谓的“硬边界”再次分开，还是他们能够畅通无阻地跨越两地边境往返和运输货物。
