既可以做情态动词又可以作为实义动词。
1）情态动词：
need + do sth
need not do sth/needn't do sth (否定）
例子：I need go to my father's factory now.
I needn't go to my father's factory now.
用法如can, must, may, might等一样。
如果实在想不出就把need想成can，慢慢就会了。
2）实义动词：
need + to do sth
don't/doesn't need to do sth (否定）
例子：I need to go to my father's factory now.
I don't need to go to my father's factory now.
情态和实义间基本没有太大区别。关键看他怎么问你。这种题目多数在选择题中比较多。看问题时候找找句子中有没有" to " " don't/doesn't" 这类比较明显的暗示来作出回答。
PS: 口语中need作为情态动词多一些。
