Задача 1
Условие (кратко)
Вставить was, wasn't, were или weren't в четыре мини-диалога: где был Mark вчера вечером, была ли Annie в школе, были ли дети дома, были ли ты и Sophie в торговом центре.
Решение
Was/wasn't — с I, he, she, it и одним человеком; were/weren't — с you, we, they и несколькими людьми.
- Where were you last night, Mark? — I was at the cinema with Peter. (С you — were, с I — was.)
- Annie wasn't at school yesterday. — Yes, I know. She was sick. (Annie не была в школе, потому что болела.)
- Were the children at home yesterday morning? — No, they weren't. They were at the zoo. (The children — они, were; дети были в зоопарке, значит дома их не было.)
- Were you and Sophie at the mall yesterday morning? — Yes. We were in Jenny's clothes shop because there was a sale on. (You and Sophie — двое, were; a sale — одна распродажа, there was.)
Ответ
1 were, was; 2 wasn't, was; 3 Were, weren't, were; 4 Were, were, was
Почему так
Was — для одного (I, he, she, it), were — для you и нескольких; отрицание и вывод о «да/нет» берём из смысла диалога.
