"Have to" 是一个情态动词短语,用于表示必须要做某事或者不得不接受某种情况,也可以表示义务、责任或建议意味。它通常在英语中用来表达强制性的、必须要遵守的规则、约定和法律等方面。
例如:
I have to go to work today.(我今天必须去工作。)
You have to follow the rules.(你必须遵守规定。)
They have to wear a mask in public places.(他们必须在公共场所戴口罩。)
We have to be at the airport by 6 pm.(我们必须在下午6点前到达机场。)
注意:在口语中,have to可以缩写成 "have got to" 或 "gotta"。

have to的用法如下:have to 后接动词原形。
Have to是情态动词 ,意思是“必须、 不得不”。have to的三单形式是 has to 。
