Нужно перевести предложения из Active в Passive. We invite war veterans

Необходимо перевести предложения из Active в Passive. We invite war veterans to watch the parade, the fireworks and take part in celebrations. We also invited them to attend school meetings. Last year we celebrated the 66 anniversary of the Victory. It is unfair, but every year we see fewer and fewer veterans. But we are sure that we will always remember their heroism. Помогите пожалуйста. очень надобно!!!!!
