Penjelasan:

- Dalam sebuah kalimat passive, tidak peduli tense kalimatnya dalam tense apa, verb harus dalam bentuk verb-3.

Dalam sebuah kalimat passive, sebelum verb-3 selalu kita temukan auxilliary verb (sering disebut auxilliary saja). In adalah kata kerja pembantu (jadi bukan kata kerja utama kalimat itu),

Jadi dalam kalimat passive, struktur utamanya selalu begini:

subjek + auxilliary verb + verb 3

Auxilliary verb ini berbeda-beda tergantung tense kalimatnya.

Dalam kalimat simple present kita pakai is/am/are (lihat jawaban soal 5)

Dalam kalimat simple past kita pakai was/were (lihat jawaban soal 2)

Dalam kalimat future atau kalimat dengan modal verb kita pakai modal + be (will be, shall be, should be, can be, may be, dll, lihat jawaban soal 3 dan 4)

Dalam kalimat perfect tense kita pakai have been, has been, had been (lihat jawaban soal 1)

Dalam kalimat present continuous kita pakai: is being/ are being atau am being (tidak ada di soal)

Contoh:

I am throwing the ball (present continuous tense, active)

The ball is being thrown by me (present continuous tense, passive)
