need有2种词性
1,情态动词 就是你说的need do
2, 实意动词 就是need to do和need doing
need doing表示被动 我的头发需要被剪了.就是说主语和need 的关系式被动.A就不能表现被动的意思了

因为need本身已经是谓语动词了,你不能再放个动词原形在它后面做宾语。
一个句子里,在没有连词连接的情况下,只能有一个谓语动词的。

need doing=need to be done 头发是被剪的,所以要用被动

need to to done/ need doing
所以C need 已经是动词了啊 不会在用动词cut的~

need doing意思是需要被做,用被动
