Rules for changing Tense in Passive Voice

Active    voice  کو   Passive    voice   میں تبدیل کرنے کے مندرجہ ذیل اُصول ہیں۔
        subject     اور    object  کی جگہوں کو آپس میں تبدیل کیا جاتاہے۔    subject   جملہ میں    object   کی جگہ پر چلا جاتا ہے، اور      object   جملہ میں   subject      کی جگہ پر آجاتا ہے
        Passive    voice    میں ہمیشہ   verb    کی تیسری فارم کا استعمال کیا جاتاہے، مثلاً   written,     eaten,۔
        Passive    voice  میں   subject   سے پہلےہمیشہ لفظ   “by”   کا استعمال کیا جاتا ہے۔
        اُوپر دئیےگئے تین بنیادی اُصول سارے   Tenses   کے لیے ایک جیسے ہیں۔ لیکن   Passive    voice   میں   auxiliary     verb  یعنی       is,     was,     will,     had   کو تبدیل کرنے کے    rules   مختلف   Tenses   کے لیے مختلف ہیں، جِس کی وضاحت نیچے کی گئی ہے۔
