need to do里面，need是行为动词，如果是否定句，要说don't/doesn't need to do.疑问句要说do/does sb. need to do....

need do里面，need是情态动词，如果是否定句，要说needn't do。如果是疑问句，要说need sb. do....

need to 此时need为实意动词主语是人
need do 此时need为情态动词

need do和need to do need 是不是加 to do need to do 和need do 的区别 need to do 和need do意思有什么区别? need to do sth 和need do sth的区别 need to do和need doing的区别 need doing 和 need to do 有什么区别？ need to do sth和need doing sth 的区别 no need doing 还是no need to do ? “need doing sth”“need to do sth”哪里不同？
