Penjelasan:

Kalimat passive adalah kalimat di mana subjek kalimatlah yang menerima aksi dari kata kerja yang disebutkan dalam kalimat tersebut.

Kalau dalam kalimat aktif, subjek kalimat adalah yang melakukan kata kerja tersebut.

Contoh dalam bahasa Indonesia:

Saya menyapu halaman. (kalimat aktif)

Saya sebagai subjek kalimat adalah pelaku dari kata kerja (menyapu).

Kalau dirubah ke kalimat passive, maka:

Halaman disapu oleh saya.

Di sini subjek kalimat yaitu halaman, adalah pihak yang menerima atau terkena dari aksi "menyapu" itu , bukan pihak yang menyapu.

Dalam bahasa Indonesia biasanya kalimat aktif ditandai dengan kata kerja dengan awalan me- (menyapu, mencuri, memakan, menyiram, memukul dst)

dan kalimat pasif ditandai dengan kata kerja berawalan di- (disapu, dicuri, dimakan, disiram, dipukul dst).

Dalam bahasa Inggris perubahan me- menjadi di- terhadap kata kerja (verb) dilakukan dengan cara:

merubah verb menjadi to be + verb 3

Apa to be nya? Itu tergantung tense kalimat.

Perhatikan satu persatu jawaban di atas, bagaimana to be itu berbeda beda tergantung tense kalimat.

Dalam simple present tense, komposisinya adalah: is/am/are + verb 3

(Is , am atau are dipakai tergantung subjek kalimat, apakah I, you dst, apakah singular atau plural)

Dalam simple past tense, komposisinya adalah: was/were + verb 3

(Was atau were tergantung subjek kalimat, apakah I, you dst, apakah singular atau plural)

Dalam present perfect tense, komposisinya adalah: have/has + been + verb 3

(Have, has  tergantung subjek kalimat, apakah I, you, apakah singular atau plural)

Dalam simple future tense, komposisinya adalah: will  + be + verb 3
