have done
固定搭配,使某事被做

我想知道你为什么会觉得要用cuts。

have...cut 是固定用法。

全部展开

这里have是使役动词，使役动词的用法见下：
　　使役动词 (例子）Causative verb 　
1.使役动词是表示使、令、让、帮、叫等意义的不完全及物动词,主要有leave.get.keep.make(使,令), let(让), help(帮助), have(有；让；从事；允许；拿)等。　　
2.使役动词后接受词,再接原形不定词作受词补语。　　接宾语时，人称代词用宾格。
He made me(宾格) laugh. 　　他使我发笑。　
let him go. 　　我让他走开。
I helped him repair the car. 　　我帮他修理汽车。
Please have him come here. 　　请叫他到这里来。
3.使役动词还可以接过去分词作受词补语。　
I have my hair cut every month. 　　我每个月理发。

have sth do...固定搭配，语言这东西是人们长期生活中约定俗成，没有什么为什么的。

这里是个句型：have sth. done 指请某人做某事 cut这里是cut的过去分词

你觉得前面有个it，所以以为它是要加s是吧，学英语有时候思维固定了就会这样，没事的，多看就能灵活一些啦，加油噢

这儿的cut是过去分词，不是一般现在时。。。所以构成have。。。done的结构。因为it表示my hair，my hair 和cut是一种被动的关系
