Ответ:

1. Marry had to finish her project yesterday.

2. We sometimes have to wear our uniform to school.

3. Susie will have to get up early tomorrow.

4. Mark has to play the guitar every day.

Объяснение:

В первом предложение ошибка? Там написано his project. Но ведь речь о Мери, проект ее, значит her project.

Have to:

I have to

You have to

We have to

They have to.

Has to используем с третьим лицом в единственном числе настоящее время. Present simple.

He has to.

She has to.

It has to.

В прошедшем времени будет had у всех.

И в будущем времени будет will have to у всех.
