Penjelasan:

Dalam membentuk passive voice harus diperhatikan:

- verb selalu harus dalam bentuk verb-3

- dalam kalimat dengan modals verb maka rumus umumnya adalah:

a) subjek + modals + be + verb 3 (untuk bentuk tense simple, entah itu simple present, simple past atau simple future tense)

Contoh:

1 ) I will take the book (simple future, active)

   The book will be taken by me (passive)

2)  She can sing that song (simple present, active)

     Thet cong can be sung by her (passive)

3)  She could finally cook the cake yesterday. (simple past, active)

    The cake finally could be cooked by heryesterday. (passive)

b) subjek + modals + have + been + verb 3 (untuk bentuk perfect, entah itu present atau past, atau future perfect)

Contoh:

1) You will have passed the limit by this time tomorrow (future perfect tense, active)

  The limit will have been passed by you by this time tomorrow (passive)

2) He could have finished the work last night at 10 PM (past perfect, active)
