sure
★★★★★
🇺🇸 /ʃˈʊɹ/
🇬🇧 /ʃoː/
sure 的核心意思是“确定、可靠、没有疑问”，也可表示“肯定地”以及口语中的“当然、好的”。
💡 记忆钩子
把 sure 想成一块稳固的地面：站在上面很安全，所以事情“可靠”；心里站得稳，所以“确定”；说话时把这种确定直接说出来，就是“肯定地”或“当然”。
📝 学习建议
- 先掌握形容词的“确定、可靠”和口语答语“当然、好的”，再学习副词用法。
- 不要把 sure 只理解成“安全”；它常表示对事实或判断有把握。
📖 中文释义
adj
-
core 可靠的；稳妥的📖 指某件事很可靠，结果有把握，不容易失效或出问题。重点不是人的主观相信，而是事情本身值得依靠。💡 常见搭配是“a sure way”或“a sure thing”，表示稳妥的方法或十拿九稳的事情。用于人时通常说某人可靠，但不要把它机械地当作“安全”的同义词。语气可以很日常，也可以用于正式说明。This is a sure way to save time.这是节省时间的稳妥办法。Her quick judgment is a sure guide in difficult situations.遇到困难时，她的快速判断是可靠的指引。
-
core 确信的；确定的📖 指人对某个事实或判断没有疑问，心里很有把握。这里强调的是主观上的确信，而不是事情本身必然可靠。💡 常见结构是“be sure of something”和“be sure that...” 。否定形式“not sure”很常用，表示“不确定”，并不一定表示完全反对。不要把“be sure”误译成只表示“保证安全”。I am sure that we have met before.我确定我们以前见过面。Are you sure about this decision?你确定要做这个决定吗？
-
common 必定会；务必📖 表示某人或某事确定会按所说的方式发生；用于祈使或提醒时，也表示“务必做某事”。它把“确定”延伸到了行动和结果上。💡 最常见结构是“be sure to do something”，例如提醒别人务必做某事；也可用“be sure that...”说明确定的结果。这个结构通常不是“对做某事有把握”，而是“记得一定要做”。Be sure to bring your keys.务必带上你的钥匙。
-
rare 安全的📖 这是较旧的用法，表示没有危险、处于安全状态，可看作“可靠地受到保护”的延伸。💡 这一义项在现代普通英语中基本不用，现代表达通常用 safe 或 secure。阅读古旧文学时可能遇到“be sure”表示安全，但不要在日常会话中主动采用。obsolete
-
rare 订婚的📖 这是过时的婚姻用语，表示已经订婚或许诺结婚，与现代常见的“确定、可靠”不是同一常用义项。💡 该义项只在历史文本或古旧语境中出现。现代英语应使用 engaged to someone 表示“与某人订婚”，不要用 sure 表达这个意思。obsolete
surer
comparative
surest
superlative
adv
-
common 当然；肯定地📖 表示说话者毫不怀疑某事是真的或会发生，相当于把“我确定”直接放进句子里。💡 常见结构是“Sure, 主语 + 谓语”，用于口语中加强肯定语气。句首的 sure 也可能是感叹词“当然、好的”，要根据后面是否有完整句子判断。正式写作中可根据语境改用 certainly 或 surely。modalSure he knows the answer.他肯定知道答案。
-
rare 必定；无疑📖 表示某事必然发生或必然产生某种结果，是“确定地”的较旧、较文学化用法。💡 现代英语中这一义项较少见，通常用 certainly、surely 或 definitely。学习时先掌握形容词和感叹词用法，不要把这种旧式副词用法当作日常首选。archaic
more sure
comparative
most sure
superlative
intj
-
common 当然；好的📖 用来直接答应请求或表示同意，意思接近“当然可以”或“好的”。它来自“我确定、我愿意”的肯定语气。💡 常见模式是“Sure, +答复”，也可以单独回答请求。根据语调，它有时只是礼貌而不十分热情的同意；不要在所有“是”或“对”的场合都机械使用它。"Could you open the window?" "Sure."“你能开一下窗吗？”“当然可以。”
-
common 嗯，可以吧📖 表示勉强或不十分明确的肯定，相当于“可以这么说”或“嗯，算是吧”。它的把握和热情通常比明确的 yes 弱。💡 常用作简短答语，尤其是在对方提出看法或偏好时。语调很重要：平淡的 sure 可能显得敷衍，重读则可能表示强烈同意。需要明确承诺时，最好补充完整答复。"Do you enjoy cooking?" "Sure, sometimes."“你喜欢做饭吗？”“嗯，偶尔喜欢。”
-
common 不客气📖 回应感谢时表示愿意帮忙、不必客气，是日常对话中的简短礼貌答语。💡 通常放在对方说 thank you 之后单独使用，或接上表示愿意继续帮忙的话。语气轻松友好，正式场合可使用更完整的礼貌表达。不要把这里的 sure 理解成对某个事实作判断。"Thanks for carrying that." "Sure, anytime."“谢谢你帮我拿那个。”“不客气，随时都可以。”

🌳 词源
源自中古英语和古法语，最终来自拉丁语，字面含有“没有忧虑、放心”的意思；与 secure 同源。
From Middle English sure, seur, sur, from Middle French sur or Old French seür, from Latin sēcūrus (“secure”, literally “carefree”), from sē- (“apart”) + cūra (“care”) (compare Old English orsorg (“carefree”), from or- (“without”) + sorg (“care”)). See cure. Doublet of secure and the now obsolete or dialectal sicker (“certain, safe”).
Displaced native Middle English wis, iwis (“certain, sure”) (from Old English ġewis, ġewiss (“certain, sure”)), as well as Middle English siker (“sure, secure”) (from Old English sicor (“secure, sure”)) with which it was cognate.
