词义辨析

v. (动词)

need, want

• 这组词都有“需要,要求”的意思。其区别是：
• need表示因缺少而需要某物或需要做某事,尤其强调这种需要的迫切性; want表示从一般需要的意向到强烈、迫切的要求以及各种程度不同的愿望。

aux. (助动词)

needn't, mustn't

• 这两个词用在肯定形式中,意思相近,但用在否定形式中时, needn't的意思是“不必,不一定”,表示“没有义务做某事”或含有“允许…不…”的意思; mustn't则表示“一定不要,不能”,表示“禁止做某事”。

lack，need，want，require

• 这些动词均有“缺少、短少”之意。
• lack指完全短缺或数量不足。
• need语气较重，指需要必不可少的东西，强调急需。
• want侧重缺少某种必需之物，或个人渴望得到的东西。
• require使用广泛，语气较轻。强调急需时可与need换用，但有时暗示所需的人或物是完成某一任务必不可少的。

词源解说

• ☆ 直接源自古英语的nied，意为需要，责任，义务；最初源自原始日尔曼语的nauthis，意为暴力，强迫。
