英特尔、高通和英伟达3大芯片巨头的CEO即将赶赴华盛顿，游说拜登政府放弃推出新的对华芯片出口限制。请看本报昨日的报道：

Major U.S. semiconductor companies are embarking on a last-ditch effort to head off new curbs on their sales to China, with senior executives planning to visit Washington this week to discuss China policy with administration officials and lawmakers.

报道中的last-ditch effort就是“最后的努力”，last ditch的说法源自过去战争中挖壕沟的做法，译为“最后一道防线”，用以形容“一系列失败后的最后一搏”。
