Robert had a book in his hand but he ............................................ it.

Решение:

Используем Past Simple для действия, которое не произошло в прошлом. Отрицательная форма — 'did not' + инфинитив без 'to'. Глагол 'read' в Past Simple — 'read' (не читается как 'red').

1. Robert had a book in his hand but he did not read it.

Ответ: did not read
