English. Как сказать: "Подсади меня, чтобы я смог залезь на крышу."

В английском такого рода действия строятся по модели help + адресат + предлог, указывающий направление (up, down, into, out of, onto) + сам объект. Например, помочь кому-то выйти из автобуса - help somebody out of a bus. Здесь та же ситуация. Help me onto the roof или Will/Would/Could you get me onto the roof? Вовсе необязателен второй глагол (хотя он подразумевается), так как для разговорной речи такие команды редко отличаются полносоставными предложениями. Например, подсадить кого-то на велосипед: (a) to help sb on to the bicycle и (b) to help sb (to) mount the bicycle. Другой пример с лошадью: A trainer helped the actor onto the horse right before filming began and waited just off-camera.
