need后面加to吗
当做实义动词时加to，need to do sth。做情态动词时不加to，needn’t do。情态动词本身有一定的词义，表示语气的单词。但是不能独立作谓语，只能和动词原形一起构成谓语。
need作情态动词的用法
（1）need用作情态动词时表“必须、必要”，后直接跟动词原型，need+do，否定needn’t +do
（2）need无人称、数的变化（第三人称单数不加s），也没有非谓语形式（不定式、分词）
（3）注意：need用作情态动词时常用于否定句和疑问句中
（4）must引导的一般疑问句的否定回答必须使用needn't，肯定回答用must。
need作实义动词的用法
1、need + something(名词） 需要某物
2、need to do something 需要做某事
3、need doing = need to be done 需要……
4、need somebody to do something 需要某人做某事
