今天我们要学的词是 pivotal.
pivotal 的意思是关键性的，核心的。U.S. officials believe a recording pivotal to the case of murdered journalist Jamal Khashoggi doesn’t appear to connect the Saudi crown prince to the killing. 美国官员认为，沙特记者卡舒吉遇害一案至关重要的录音似乎没有将沙特王储牵连进来。
Mishaps, protests and litigation are overshadowing the vote recount in Florida’s pivotal races for governor and Senate. 至关重要的佛罗里达州州长和参议员竞选的重新计票由于各种问题、抗议和诉讼而蒙上阴影。
