My favorite character is Harry Potter. When I was younger I didn’t want to read the book. I was curious about classical literature or some adventure stories. Later my friends invited me to the cinema. I was not busy and so that was the evening when I first met Harry Potter and his brave friends.
I can not say that I have become a Potter’s fan. He is little bit strange, but at the same time he is brave and very smart. He knows how to act, how to communicate with people and how to be a good friend. Sometime we have good and bad days, but we have to be strong and still trust people.

1)I was listening to the radio when the phone rang.

.2) ... Tom and Mary were walking

3) Grandma arrived last Sunday.

4) Ben was dancing while his sister was singing.

5. The children had breakfast and then they went to school.

Объяснение: Past Continuous используется, чтобы описать действие в процессе в то есть в какой-то определённый момент в кто-то или что-то было в процессе выполнения какого-либо действия. Например, вчера в 5 часов вечера я делал уроки - Yesterday at 5 I was doing homework. Или когда одно длительное действие прерывается другим действием в Например, я смотрел телевизор, когда ты позвонил - I was watching TV when you called. Ещё МОМЕНТ, слово while всегда указывает на Continuous в любом времени, не только Past.

Past Simple же описывает обычное, завершенное действие в НАПРИМЕР, Он посмотрел этот фильм на той неделе. He watched this movie last week.
