"ought to"是英語中常用的情态動詞短語,主要表達以下三層含義:
道德義務或責任 表示基于道德準則或社會規範應盡的責任,例如:"Citizens ought to obey traffic regulations"(公民應當遵守交通法規)。這種用法強調社會共識的正确行為。
建議或最佳選擇 用于提出建設性意見,如:"You ought to get eight hours of sleep for better health"(為保持健康應該保證八小時睡眠)。此時與"should"相似,但語氣更客觀。
合理推測 表示根據現有信息得出的邏輯結論,例如:"The delivery ought to arrive by noon"(快遞理應在中午前到達)。這種推測基于已知事實的合理預期。
語法結構方面,"ought to"後接動詞原形,否定形式為"ought not to",疑問句需将主語置于情态動詞前。與"should"相比,"ought to"更側重客觀責任而非主觀判斷,例如法律條款中更傾向使用"ought to"表達義務。
權威語言學家Quirk在《英語語法大全》中指出,該短語源自古英語"āgan"(欠債),延伸出"應盡義務"的核心語義,這種曆史演變使其在正式語境中更具約束力意味。
