Once upon a time there 1) ................ (be) two mice: the Town Mouse and the Country Mouse. The Country Mouse 2) ................ (visit) the Town Mouse. The Town Mouse 3) ................ (cook) burgers and chips for his friend but the Country Mouse 4) ................ (not/like) it there. The dog 5) ................ (want) to eat him.

Смотри, тут всё просто: нужно раскрыть скобки, поставив глаголы в прошедшем времени. Поехали!

1) was - в прошедшем времени глагол "to be" в форме для единственного числа.

2) visited - правильный глагол, поэтому добавляем окончание -ed.

3) cooked - правильный глагол, добавляем окончание -ed.

4) didn't like - в прошедшем времени отрицание образуется с помощью did not (didn't) + глагол в начальной форме.

5) wanted - правильный глагол, добавляем окончание -ed.

Получаем:

Once upon a time there was two mice: the Town Mouse and the Country Mouse. The Country Mouse visited the Town Mouse. The Town Mouse cooked burgers and chips for his friend but the Country Mouse didn't like it there. The dog wanted to eat him.

Ответ:
