6. "I have lunch at school." a. Pete says that b. Pete said that

Решение:

Преобразуем прямую речь в косвенную. Прямая речь содержит глагол "have" (Present Simple). Вводная конструкция "Pete says" – Present Simple, "Pete said" – Past Simple. При переходе в косвенную речь, если вводная конструкция в Past Simple, время глагола изменяется на Past Simple (Present Simple -> Past Simple).

• 6.a. Pete says that he has lunch at school.
• 6.b. Pete said that he had lunch at school.

Ответ:

• 6.a. Pete says that he has lunch at school.
• 6.b. Pete said that he had lunch at school.
