2 Read about Lindas winter holidays. And write about her last winter holidays.

Every winter I go to the mountains. I stay in a beautiful hotel. The rooms in it are very comfortable! I take my skis and sledges. It is frosty and snowy in the mountains. My friends and I can sledge and ski. In the evenings we come to our rooms and have a rest. We watch TV, play in the snow, make snowmen or read books. We go to bed late in the evenings.
пример ( Last winter Linda went to the mountains. She staved. )
