Давайте разберем, как превратить утвердительные предложения в отрицательные в прошедшем времени на английском языке. В каждом случае используем вспомогательный глагол "was" или "were" в отрицательной форме "wasn't" или "weren't".
Valya was at the festival last Sunday.
- Valya wasn't at the festival last Sunday.
It was hot last Saturday.
- It wasn't hot last Saturday.
You were at the post office last Monday.
- You weren't at the post office last Monday.
We were at the sports centre last Wednesday.
- We weren't at the sports centre last Wednesday.
They were sick last week.
- They weren't sick last week.
He was at the station last Tuesday.
- He wasn't at the station last Tuesday.
В каждом примере мы просто добавляем "not" после "was" или "were", чтобы сделать предложение отрицательным. Это основной способ образования отрицательных форм в прошедшем времени для глагола "to be".
