Question

英语问题，很简单的求助

You need to come today. 你今天需要来。
You don't need come today. 你今天不需要来。
有区别吗？为什么一个加to另一个不加？

Answer 1

严格来说，第二句应该有错误！
need的用法是
1.实意动词。need sth
need to do sth (主语为人)
need doing sth(主语为物，表达一种被动含义)
eg. She needs to pay 30 dollars for the dress.
2.情态动词。后跟动词原形，无人称与时态的变化。
eg.She need pay 30 dolars for the dress.
