“你是我最致命的弱点”常见的英语表述有：“You are my most fatal weakness.” 或者 “You are my deadliest weakness.”
“fatal” 意思是“致命的；毁灭性的”，“most fatal” 强调“最致命的”。“weakness” 指“弱点；缺点”。
例如：This mistake was his most fatal weakness in the competition.（这个错误是他在比赛中最致命的弱点。）
“deadliest” 是“deadly”的最高级形式，“deadly” 有“致命的；极度的”之意。
例如：The di a is one of the deadliest in the world.（这种疾病是世界上最致命的疾病之一。）
所以，用“You are my most fatal weakness.” 或者 “You are my deadliest weakness.” 来表达“你是我最致命的弱点”是比较准确和常见的。
