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.
During the holidays, the child rests, relaxes and forgets absolutely everything that he learned for a whole year at school.All the same, after each subsequent quarter, it becomes more and more difficult for children to learn. After spring break, when students are supposed to come to their classes fresh and rested, we see tired, tortured children.Regular schools do not provide children with enough knowledge, and some schools operate on an outdated and boring curriculum.So I came to the conclusion that if you shorten the holidays it will not lead to success.
