Jawaban:

• 1. cookies are made by my mother twice in a week. (simple present tense)
• 2. a glass of avocado juice was drunk by the little girl. (simple past tense)

Penjelasan:

• kedua Passive voice diatas menggunakan pola simple present tense dan simple past tense, karena jika present tense, verb diakhiri (S) dan keterangan waktu nya Twice,
• sedangkan simple past tense, verb menggunakan verb 2.

_

→ di Passive voice, subject menerima tindakan, bukan melakukan tindakan, justru objek yang dikenai tindakan (subject menjadi object, object menjadi subjek)

_

pola Passive voice simple present tense

• O + tobe (is/am/are) + verb 3 + by + S

pola Passive voice past tense

• O + tobe (was/were) + verb 3 + by + S
