Напишите 3 предложения в непрерывном времени; превратить их в отрицательные и вопросительные формы​

Если я правильно помню, то так строится непрерывное (Past Continuous):

I was running to school. I wasn't running to school. Was I running to school?

I was eating. I wasn't eating. Was I eating?

I was swimming. I wasn't swimming. Was I swimming?

Могу ошибаться, за ошибки не бить.
