Another modal verb that we often use is 'has to' or 'have got to.' This is a slightly different kind of modal verb, called a phrasal verb. Although we use it in the same way we would use the other modal verbs, it does change depending on the subject.
| Subject | have got to OR have to | Verb | |
|---|---|---|---|
| I | have to | run | 10 km for gym class next Monday. |
| You | have to | run | 10 km for gym class next Monday. |
| She | has to | run | 10 km for gym class next Monday. |
| He | has to | run | 10 km for gym class next Monday. |
| It | has to | run | 10 km for gym class next Monday. |
| We | have to | run | 10 km for gym class next Monday. |
| You | have to | run | 10 km for gym class next Monday. |
| They | have to | run | 10 km for gym class next Monday. |
When we use the phrase 'have got to' we usually use contractions:
| I have got to | I've got to |
| You have got to | You've got to |
| She has got to | She's got to |
| He has got to | He's got to |
| It has got to | It's got to |
| We have got to | We've got to |
| You have got to | You've got to |
| They have got to | They've got to |
Remember that we never use contractions when using the phrase 'has to.' We always use the full form.
We can also use 'have to' to make negative sentences.
| Subject | do not | have to | Verb | |
| I, You, We, You, They | don't | have to | bring | books to school next week. |
| He, She, It | doesn't | have to | bring | books to school next week. |
