7. I ........ get up early on Wednesday, but I ....... get up early on Sunday.

7. Необходимо выбрать между have to, don't have to, has to, doesn't have to.
Поскольку подлежащее I (я) стоит в единственном числе, то has to, doesn't have to не подходят. Далее, по смыслу: Я должен вставать рано в среду, но я не должен вставать рано в воскресенье.

I have to get up early on Wednesday, but I don't have to get up early on Sunday.

Перевод: Я должен вставать рано в среду, но я не должен вставать рано в воскресенье.

Ответ: I have to get up early on Wednesday, but I don't have to get up early on Sunday.
