• need在做情态动词和实义动词的问题need在做情态动词和实义动词时是不是虽然用法不同,但表示的意义和意思相同?比如说He needs to have a rest .He need have a rest.意思和表达的意思是不是相同?如果相同那我是不是在用的时候He needs to have a rest .和 He need have a rest.可以通用?实义动词时的 need变否定时 not 是加在 need 前面还是加在不定式中?He doesn't need to have a rest.He needs not to have a rest.是不是一般有宾语重句的句子中,都要否定前移.（即把重句谓语的否定移到主句的谓语上）?我的意思是need在做情态动词和实义动词时的意思是不是相同,意思是不是一样,是不是可以通用,也就是用哪个都行.He needs to have a rest .He need have a rest.
