Penggunaan Past Future Perfect Tense

Karena kedua tensis ini mirip, posting ini menggunakan konsep dan contoh-contoh kalimat pada future perfect tense. Perhatikan dan bandingkan perubahan predikat dan keterangan waktunya. Gunakan analogi pada past future tense jika masih bingung. Are you ready? Let’s get started.

Past Future Perfect Tense digunakan:

1. Untuk menyatakan kembali kejadian/aktivitas yang pernah diprediksi atau direncanakan akan sudah terjadi/sudah selesai dilakukan sebelum atau hingga batas waktu tertentu di masa lampau.

Note: Pada umumnya, tensis ini diawali oleh clause yang mengandung makna prediksi, ekspektasi atau rencana. Verbs yang digunakan antara lain: think, hope, expect, plan, intend, assume, etc.

Contoh:

1. I predicted that by 3 p.m. yesterday, I would have finished reading this book. (Saya berharap bahwa sebelum jam 3 sore kemarin, saya akan sudah selesai membaca buku ini).
2. I thought Barcelona would have scored three goals when the first half was over. Because its opponent was tough, however, it didn’t score even a single goal. (Saya kira Barcelona akan telah cetak 3 goal ketika babak pertama berakhir. Namun karena lawannya tangguh, Barcelona bahkan tidak cetak goal sama sekali).
3. Because of the terrible traffic we knew that dad’s plane would have already arrived by the time we got to the airport yesterday.
4. My dad planned that he would have been home when my mom gave birth last month. He didn’t make it though because he had an immigration documentation problem.
5. I thought I would have already fallen asleep by the time Joni got home last night. I don’t know why I was still awake when he did.

Note: Jika pada future perfect tense, time clause dinyatakan dalam simple present tense, pada tensis ini dinyatakan dengan simple past tense. Misalnya: when the first half was over (pada contoh 2), by the time we got to the airport (pada contoh 3), etc.

2. Untuk menyatakan kembali kegiatan/aktivitas yang pernah diprediksi atau direncanakan akan sudah terjadi/sudah selesai dilakukan sebelum kejadian/aktivitas yang lain di masa lampau.
