| 释义 | 〔need〕The auxiliary forms ofneed are used primarily in present-tense questions, negations, and conditional clauses. They differ subtly in meaning from the main verb forms in that they always refer to an externally imposed obligation.Hence one might sayYou needn't (or less formally, don't need to ) fill out both forms, but where the sense of necessity is internal to the subject,only the main verb can be used: Need 的助动词形式主要用于现在时态的疑问句、否定句和条件句中。 它们在意思上和用作实义动词的形式有细微的区别，它们总指外部加强的压力。因此我们可以说你没必要 （或不太正规的 don't need to ) 填两份表格 ， 但是对于物体来说需要的意思是内在的，所以只能用实义动词： 〔say〕And there is no need to mention. Used to allude to things that fill out an idea or argument:更不用说：没必要提及。用来暗指证明某种想法或理由是正确的事情：〔worry〕There is nothing to worry about; there is no need to be concerned:没什么可担心的；没必要着急的： |
