Active and Passive Sentence in Present Form

Kata kerja transitif mempunyai dua voice (ragam gramatikal), aktif dan pasif.
1) Bentuk aktif adalah orang, binatang, atau benda yang ditunjukkan oleh subjek dikatakan
melakukan sesuatu pada yang lain.
Contoh: Karim killed a tiger. Karim membunuh seekor harimau

2) Bentuk pasif adalah orang, binatang atau benda dikatakan menderita sesuatu dari sesuatu yang lain.
Contoh: A tiger was killed by Karim. Seekor harimau dibunuh oleh Karim
Bentuk pasif :

Aturan-aturan :
a) Kata kerja transitif tidak digunakan dalam bentuk pasif, kecuali kalau kata kerja itu menggunakan cognate object dalam bentuk aktif.
Aktif : She sang a fine song. Ia menyanyikan sebuah nyanyian yang merdu
Pasif : A fine song was sung by her. Sebuah nyanyian yang merdu dinyanyikan olehnya
b) Bilamana kalimat diubah dari bentuk aktif ke pasif, objek untuk kata kerja aktif menjadi subjek untuk kalimat kerja pasif.
objek untuk kata kerja aktif :
Aktif: Linda can make tarts. Linda dapat membuat kue tart
Subjek untuk kata kerja pasif :
Pasif: Tarts can be made by Linda
c) Retained object (objek yang tetap dipakai/dipertahankan dalam pasif)
Dua buah objek dalam kalimat aktif, ketika diubah menjadi kalimat pasif, masih tetap ada sebuah objek dipertahankan, objek ini dinamakan retained object. Objek ini mungkin objek tak langsung dari kata kerja aktif atau objek langsung dari kata kerja aktif.
Objek tak langsung dari kata kerja aktif 
Kata Kerja aktif Kata kerja pasif

Objek langsung dari kata kerja aktif
Kata Kerja aktif Kata kerja pasif
We gave him a prize He was given a prize by us
