как я понимаю, там надо писать формы глаголов в Past Perfect, просто на одной строчке везде слово had, а на второй past participle, то есть
be - had been
do - had done (пример)
see - had seen
know - had known
take - had taken
write - had written
Past Perfect-нижняя строчка
had been,
had done,
had seen,
had known,
had taken,
had written
Верхняя строчка всё правильно
