英汉词典

Need sometimes behaves like an ordinary verb, for example 'She needs to know' and 'She doesn't need to know' and sometimes like a modal, for example 'She need know', 'She needn't know', or, in more formal English, 'She need not know.' need
有时用作普通动词，例如：She needs to know (她需要知道)，She doesn't need to know (她不需要知道)。有时 need 用作情态动词，例如：She need know, She needn't know 或更为正式的说法：She need not know。
