passive

Dear native speakers,

In a grammar book I read that three tenses do not have passive forms. These tenses are: present perfect progressive, simple future progressive, and past perfect progressive. Is it true that we can't make the following tenses into passive?

Thanks.

Try it and see.

What do you mean? I'm not a native speaker and may not be able to understand it!

You say you are an English teacher, you must be able to construct sentences using passive voice.
