9. "I am going to invite you." a. He says that b. He said that

Решение:

Преобразуем прямую речь в косвенную. Прямая речь содержит конструкцию "am going to" (Present Continuous, будущее время). Вводная конструкция "He says" – Present Simple, "He said" – Past Simple. При переходе в косвенную речь, если вводная конструкция в Past Simple, время глагола изменяется на Past Simple (am/is/are going to -> was/were going to).

• 9.a. He says that he is going to invite you.
• 9.b. He said that he was going to invite you.

Ответ:

• 9.a. He says that he is going to invite you.
• 9.b. He said that he was going to invite you.
