Объяснение:
При преобразовании прямой речи в косвенную нужно применять правило согласования времен: например, Present Simple заменяется на Past Simple, Past Simpleв прямой речи заменяется на Past Perfect в косвенной.
Иногда необходимо изменить форму глагола (как в первом предложении, где используется герундий).
