“be supposed to” 是一个英语短语动词,其含义和用法需结合语境判断。以下是详细解析:
一、核心含义
“be supposed to” 的核心逻辑是表达预期、义务或假设,强调“根据规则、惯例或普遍看法,某事应当发生或某人应当做某事”,但实际情况可能与之不符。具体可分为以下三类:
-
义务或责任(Obligation)
- 解释:表示按照约定、规定或社会规范应履行的义务,但语气比should 更弱,常隐含“但实际未必做到”的潜台词。
- 例句:
- You’resupposed to wear a suit and tie to the meeting. (你应该穿西装打领带参加会议。)
- Children aresupposed to get 60 minutes of exercise daily. (儿童应该每天进行60分钟的锻炼。)
-
普遍看法或假设(Assumption)
- 解释:描述被广泛接受的观点或未经证实的假设,相当于“据说”“被认为”。
- 例句:
- The building issupposed to be one of the most secure in the country. (这座建筑据说是全国最安全的之一。)
- The entry code issupposed to be known only by the guard. (入口密码本应该只有保安知道。)
-
预期或计划(Expectation)
- 解释:表示对某事发生的预期,但实际结果可能与预期不同。
- 例句:
- I wassupposed to finish the report yesterday. (我本应昨天完成报告。→ 暗示未完成)
- The train issupposed to arrive at 5 p.m. (火车应该5点到。→ 可能晚点)
二、语法与搭配
-
结构形式
- 肯定句:主语 + be动词(根据时态变化) + supposed to + 动词原形

- 否定句:主语 + be动词 +not + supposed to + 动词原形
- 例:Youaren’t supposed to smoke here. (此处禁止吸烟。)
- 疑问句:Be动词 + 主语 + supposed to + 动词原形
- 例:Am I supposed to wear formal clothes? (我需要穿正装吗?)
-
时态变化

- 例:Sheis supposed to know the rules. (她理应知道规则。)
- 过去时:was/were supposed to
- 例:Theywere supposed to call me back. (他们本应回电话给我。)

- 物作主语:强调普遍看法或假设。
- 例:This medicineis supposed to relieve pain. (这种药据说能缓解疼痛。)
三、常见误用与辨析

- 例:Youshould apologize. (你应该道歉。→ 个人建议)
- Be supposed to:侧重客观规则或他人预期,隐含不确定性。

- Be supposed to:暗示规则可能被打破或存在例外。
- 例:Youare supposed to wear a seatbelt. (按规定应系安全带。→ 但有人可能不系)
-
与 be expected to 的区别
- Be expected to:强调他人对某事的期望或要求。
- 例:Studentsare expected to study hard. (学生被期望努力学习。)
- Be supposed to:更侧重规则或假设,不一定涉及他人直接期望。
四、使用场景
-
日常对话
- 提醒责任:
- “You’resupposed to clean your room today!” (你今天应该打扫房间!)
- 表达失望:
- “I wassupposed to get a promotion, but it didn’t happen.” (我本应升职,但没成。)
-
正式写作
- 说明规则:
- Employeesare supposed to report any safety issues immediately. (员工应立即报告安全隐患。)
- 学术假设:
- The theoryis supposed to explain the origins of the universe. (该理论被认为能解释宇宙起源。)
-
否定句的委婉表达
- 避免直接指责:
- “Youaren’t supposed to park here.” (此处不应停车。→ 比“You can’t park here”更礼貌)
五、总结
“be supposed to” 的核心意义是在规则、惯例或普遍看法下某事应发生,但实际结果可能偏离预期。其用法灵活,需注意:
- 表达义务时,隐含“可能未完成”的潜台词。
- 描述假设时,常用于转述他人观点或未经证实的信息。
- 否定形式可委婉表达禁止或规则。
通过结合具体语境,可以更准确地理解其含义。例如:
- “The hero issupposed to save the world.” (英雄本应拯救世界。→ 可能成功或失败)
- “We’resupposed to meet at 8, but she’s always late.” (我们约好8点见,但她总迟到。→ 预期与实际不符)
