Past participles can modify nouns in much the same way as adjectives.For example

1. I am told = I am a told man.

2. You are invited = You are a invited man.

3. He is questioned = He is a questioned man.

Are these sentences correct in adjective sense? If all past participles are used as adjectives then how can we identify which are in passive sense or adjective sense(be forms+past participles) without "an object" and "by" phrase??
