чтобы образовать past simple, нужно употребить вторую форму глагола. у большинства глаголов она образуется путем добавления окончания “-ed” к инфинитиву. если глагол заканчивается на “e“, добавляется просто “d“, если глагол заканчивается “y“, то она заменяется на “i” перед).
А отрицательные и вопросительные предложения в Past Simple строятся с добавления формы времени глагола “to do – did” и инфинитива смыслового глагола.
Например:
Did you arrive in time?
Didn’t you eat yet?
We didn’t go to the movies after all.
Глагол “to be” в отрицательном или вопросительном предложении в Past Simple не требует добавления глагола “to do“.
Например:
WasI late?
Was he glad?
Were you all right?
Всё, я надеюсь тебе немного

4) Yes, they often work in dangerous situations. To my mind, they put themselves in danger, because they love their job and they want to save people's lives.
5) If you want to be an emergency worker you should have a good physical form and excellent health. As for me, I don't want to be an emergency worker, because this job is too dangerous.
