I know English Grammar but not fluently.Sometimes I can"t choose the difference beetwen Past Particiiple and Passive Voice{ in interrogative se ntences}

This is possibly because the past participle is used with the verb "be" to form the passive voice in English.

be + past participle = passive voice

Examples:

The work "is finished"

His house "was made" of brick

The city "will be destroyed"

It would be helpful if you could give some examples showing what confuses you.

Where several languages use both "be" and "have" to form their past and present perfect tenses (Ich bin gekommen, je suis venu; ich habe gemacht, j'ai fait, etc.) English only uses "have"+past participle. Except in archaic usages, it is safe to assume that the structure "be"+past participle puts the sentence in the passive voice.
