Passive voice atau kalimat pasif sangat sering dipakai, terutama dalam tulisan-tulisan teknik, dimana kita lebih banyak membicarakan fakta, proses, maupun kejadian daripada membicarakan orang/pelakunya.

Passive voice disusun dengan menggunakan kata kerja bantu "be" yang sesuai dengan bentuk waktu (tenses) yang digunakan dalam active voice atau kalimat aktif, diikuti oleh kata kerja bentuk ke-3 (the past participle). Subyek dalam active voice akan menjadi "agen" (agent) dalam passive voice. Agen ini seringkali tidak disebutkan, tapi jika disebutkan maka harus didahului oleh "by" dan diletakkan diakhir kalimat.

Dalam tes-tes berbentuk Sentence Completion, seperti TOEFL, TOEIC dan Ujian Nasional, kemampuan untuk menentukan apakah sebuah kalimat memiliki kata kerja aktif atau pasif seringkali diujikan. Peserta ujian harus mampu menganalisa subyek kalimat beserta bentuk waktu (tense) dengan benar.

C. Penggunaan Passive Voice

How to Change an Active Sentence to the Passive VoiceDalam bahasa Inggris, passive voice atau kalimat pasif tidak begitu saja digunakan tanpa alasan tertentu. Ada beberapa alasan mengapa kita sebaiknya menggunakan passive voice, sebagai pengganti active voice.
  1. Jika subyek atau pelaku kata kerja aktif tidak perlu disebutkan, atau jika kita lebih menitikberatkan pembicaraan pada kejadian atau tindakan daripada pelakunya.
  2. Jika kita tidak tahu atau lupa siapa subyek atau pelaku tindakan.
  3. Jika subyek kata kerja aktif bukan merupakan orang tertentu, misal ‘people’, atau kata ganti benda tak tentu (indefinite pronoun) ‘one’.
  4. Untuk menghindari gaya bahasa yang "kaku" atau tidak lazim, atau kalimat yang tidak memiliki tata bahasa yang baik. Passive voice biasanya digunakan untuk menghindari terjadinya pergantian subyek dalam satu kalimat.
    Contoh:
    1. Kalimat "When he arrived home a detective arrested him" sebaiknya disusun menjadi "When he arrived home he was arrested (by a detective)"
    2. Kalimat "When their mother was ill neighbors looked after the children" sebaiknya disusun menjadi "When their mother was ill the children were looked after by neighbors"
Oleh karena itu, passive voice tidak selalu harus menyebutkan "by ...", karena seringkali agen (pelaku) tersebut tidak penting untuk disebutkan, atau bahkan tidak diketahui secara jelas. Jika memang agen (pelaku) penting untuk disebutkan, lebih baik kita menggunakan kalimat aktif (active voice).

D. Exercises

  1. Read the text below, which describes the insurance company’s procedure for dealing with PC-users’ problems. Fill in the gaps using the correct passive form of the verb in brackets.

In the event of a major problem requiring the removal of a user’s PC, a replacement can usually ...(supply)....
