Supposed
“Supposed” 来自 suppose（假定、认为）。作形容词时，be supposed to 表示“应该（做某事）”或“被期望”；也可表示“所谓的、据说的”，有时带怀疑语气，例如 “You’re supposed to be here at nine.”（你应该九点到这里。）
- “The train is supposed to arrive at noon.” (火车预定中午到达。)
- “You’re not supposed to use your phone in class.” (课堂上你不该用手机。)
- “This is the supposed reason for the delay.” (这据说是延误的原因。)
“Suppose” 源自拉丁语 supponere（放在下面、假设），由 sub-（在下）与 ponere（放置）构成。
“Supposed” 在 suppose 后加 -d 形成过去分词；副词形式为 supposedly。
be supposed to 在英语口语中极高频，用于规则、计划或社会期待；supposed 单独修饰名词时，常暗示“名不副实”或“未经证实”。
- 原形: suppose
- 过去式/过去分词: supposed
- 副词: supposedly
- 固定搭配: “be supposed to” (应该), “supposed expert” (所谓的专家)
把 suppose 想成“先假定是这样”，supposed 就是“被假定/被认为应该如此”。
“We were supposed to meet at the café, but the rain changed everyone’s plans.” (我们本该在咖啡馆见面，但大雨改变了大家的计划。)
