Modals of necessity - 2

Example Question Answer
I have to study tonight Do I have to study tonight? Yes, I do
She has to study tonight Does she have to study tonight? No, she doesn't

Remember: “have got to” and “have to” are modal verbs and require a simple verb to follow them.
The “to” is part of the modal; it is not an infinitive “to”.

There is only one way to express past time with these modal verbs: HAD TO.
(There is no past tense of must/have got to). Examples:

Present time Past time
We must show our passport at the airport. Last night, we had to show our passport at the airport.
I have got to pay my phone bill soon. I had to pay my phone bill this morning.
They have to go to the meeting today. They had to go to the meeting yesterday.
