Переведите на английский: его мама готовила ужин на кухне, когда я вошел.

When I entered, his mother was cooking a dinner in the kitchen.

Yesterday I spent my whole day with my friend. We were free from lessons and that was why we had much time for having fun. My friend invited me to his place. He had a big, nice house which I liked very much. When I entered, his mother was cooking a dinner in the kitchen. The smell was wonderful. She told us to seat to have dinner and then to go and play. We had dinner and went upstairs to play computer games. Then, we watched a very interesting film. Late at night I went home.
