I'd got a pet few years ago, his name was (имя питомца) I had never eaten any insects.
I'd been studying English (ну или что-то, чем ты занималась раньше долгое время: swimming, playing something и т.д.). Yesterday I had been doing my homework for 2 hours, it was awful. I'd never been in London (или любой другой город, в котором ты ни разу не была). But I'd already been in Moscow (или, опять же, любой другой город в котором ты была:)). I had been doing this exercise about 20 minutes.
