need如何区分实意动词or情态动词?

Answer 1

need既可作情态动词又可作实意动词1. need做情态动词与其他情态动词"can","may","must"的用法基本相同：肯定句need后面+动词原形；变否定句为needn't +动词原形例如：He needn't worry about it．这件事他无需担心.2. need做实意动词1）+nI need money. 我需要钱2）+to do （注意此时变否定句not要放need前面）You don't need to hurry. 你没必要着急3）+doing=need to be done （主动表被动） My hair needs washing badly. (= My hair needs to be washed badly.) 我的头发非常需要洗一洗.
