Passive Voice (Kalimat Pasif)

To begin with, Let me say that all passive sentences in English have verb 3 in them.
Examples: 1. The computer is being repaired now. (Komputer itu sedang di perbaiki sekarang).
2. That tv is watched everyday. (Televisi itu di lihat setiap hari).
3. That question has been answered. (Pertanyaan itu telah di jawab).
All passive sentences in English, if translated(di terjemahkan) in Indonesian language will be -di... . For example, -di pukul..., -sedang di baca...,-akan di bersihkan..., etc. so, here are the four basic types of passive sentences in English I have formulated.
1. -di...
...is/ am/ are + V3 (Present/ Masa sekarang)
...was/were + V3 ( Past/ Masa lampau)
The pool is cleaned(V3) every day. ( Kolam itu di bersihkan setiap hari).
My cat was kicked(V3) by Joko yesterday. (Kucing saya di tendang oleh Joko kemarin).

2. -sedang di...
...is/ am/ are + being + V3 (present)
...was/ were + being + V3 (Past)
The wall is being painted(V3) by father now. tembok itu sedang di cat oleh ayah sekarang).
The newspaper was being read(V3) by my brother when I came home last night. (Koran sedang di baca oleh saudara laki-laki saya ketika saya pulang tadi malam).

3. -telah di...
...Have/has + been + V3 (Present)
...Had + been + V3 (Past)
The question has been answered. (Pertanyaan itu telah di jawab).
Or, we can say, the question has already been answered; The question has been answered already is also possible.

4. -akan di...
