Dear Ben, Thanks for your last letter. I am very glad to get it. Yesterday I go to the cinema with my best friend. We watch an interesting film about pirates. The story was very exciting and the actors plays great. After the cinema we eated ice cream in a cafe. It were so tasty! My mom ask me to help her at home yesterday, but I forget. I feel very guilty now. What you do last weekend? Please tell me in your next letter.

Решение:

• Yesterday I went to the cinema with my best friend. We watched an interesting film about pirates. (Вместо 'go' нужно использовать 'went' (прошедшее время), вместо 'watch' - 'watched').
• The story was very exciting and the actors played great. (Вместо 'plays' нужно использовать 'played').
• After the cinema we ate ice cream in a cafe. It was so tasty! (Вместо 'eated' нужно использовать 'ate', вместо 'were' - 'was').
• My mom asked me to help her at home yesterday, but I forget. (Вместо 'ask' нужно использовать 'asked').
• What did you do last weekend? (Необходимо добавить вспомогательный глагол 'did').
