have,have got,have to的否定形式一共有几种？

Question

have既可作实义动词“有”，也可作助动词，如have been, have gone, have done，还可做情态动词，have to,不同用法的陈述句变否定句、疑问句，都有哪些变化？规则是什么？

Answer 1

做助动词:
疑问句：把have提前，如Have you been there before? Have you done your homework?
否定句，变have为haven't 。

情态动词
疑问句：用Do提问，如Do you have to do this right now? Does Tom have to go to school?
否定句：加don't，如I don't have to do it now. Tom doesn't have to go to school today.

做“有”讲的时候，和一般动词用法相同。
我知道的就是这些，希望能对你有帮助。

Answer 2

呃，这个直接在have后面加not虽然是它的否定性是，但似乎不地道啊
have
got
to的意思是“不得不”，相应的否定短语就是“不必要”
如果语境要求不严格的话don't
need
to
或needn't
都可以吧。
话说我读了这么多英文还没见过have
not
got
to
的用法。如果你在写作文的话不推荐这种用法。
