Перевести 1.она долго работала в саду.она не знала что происходит в доме. 2.не возвращайся пока не найдешь его. 3.вы давно знаете друг друга?

She was working at the garden. She didn't know what is happened at home. 2 don't come here till you find him 3 do you know each other for a while?

Я не уверенна в правильности, возможно как то так:
She worked in the garden for a long time.
she didnt know what happening in the house.
Dont come back until you find him,
how long you known each other?
