Hi! I want to propose for all foreiners this task.
Try to find and correct mistake in each sentences, and maybe you find it funny... (:
У слова "нет" нету форм изменения.
Коллеги обращения надо как-то выделять.
Кое-кто стали забывать правила согласования главных членов предложения.
If you find it intresting i will add more difficult sentences. And if it is clear for you please don't give your direct answers (lets other people to play)
