ответ:I would like to tell you about my weekend. My last weekend was not monotonous. On Friday, I was staying at home and watching TV. My friend arrived and we were watching a film on the computer in the evening. This movie was called " Fast Five 8" and it was very interesting. On Sunday, I was relaxing all day at home. In the morning, I remembered that I had homework; so I did it. In the evening, I was watching TV and afterwards I went to bed.

I think my rest depends on the season, because in winter I walk less than in summer. In summer there are a lot of entertainments!

I prefer to spend my weekends with my parents and friends because I have a lot of fun with them. I love my weekend and my family!

Перевод:Я хотел бы рассказать тебе о моих выходных. Мой последний уик-энд не был однообразный. В пятницу я остался дома и смотрел телевизор. Пришел мой друг и мы вечером смотрели фильм на компьютере. Этот фильм назывался «Форсаж - 8", и это было очень интересно. В воскресенье я отдыхал весь день дома. Утром я вспомнил, что у меня было домашнее задание, поэтому я сделал его. Вечером смотрел телевизор, а потом пошел спать.

Я думаю, что мой отдых зависит от сезона, потому что зимой я меньше гуляю на улице, чем летом. Летом есть много развлечений!

Я предпочитаю проводить свои выходные со своими родителями и друзьями, потому что мы с ними много веселимся. Я люблю свои выходные и свою семью!
