问题描述:

She doesn't have to wear a uniform to school.这句子里have是不是应该换成has?
这是某个网站的例句.she第三人称单数不是应该跟has的吗?是例句错了还是怎样?求解答.

这个句子 是正确的,助动词DOESN‘T 后接动词原形have (不能用 has )
是不是didn't,don't,doesn't这样的否定句后面都跟原型have?对,助动词后接动词原形。如果后面的动词是HAVE, 就是用原形


又如
He went to the park yesterday .
He didn't go to the park yesterday .
