Pada prinsipnya, past future tense mirip dengan
simple future tense dan ketentuan-ketentuan yang berlaku pada simple future
tense umumnya juga berlaku pada past future tense. Tetapi, karena bergulirnya
waktu, simple future tense bergeser dari future time ke past time menjadi past
future tense. Untuk menjelaskan ini, di sini akan digunakan konsep dan
contoh-contoh pada future tense.
Adapun rumus dari
present perfect continuous tense adalah sebagai berikut :
S + Would +
Verb 1 + O + Modifier
|
S + To Be
(Was/Were) + Going To + Verb 1 + O + Modifier
|
Contoh :
1) Farmers in Jati Bali would grow rice crops last month.
2) Some students would conduct research on vegetative plant propagations last
semester.
3) Transpiration would start to increase at 8 a.m. this morning.
Past Future Tense, seperti halnya simple future
tense, dapat digunakan dalam 5 kategori, yaitu:
1. Untuk
menyatakan kembali kejadian/aktivitas yang pernah diprediksi akan
terjadi/dilakukan pada saat tertentu di masa lampau.
Untuk memahami perbedaann past future tense dengan
simple future tense, mari kita perhatikan
contoh-contoh kalimat yang diberikan pada simple
future tense berikut ini:
1) According to the weather forecast, it will rain tomorrow
2) None of us have done the homework the teacher
told us to do. He will be very
disappointed when he finds out.
3) Ronny is going
to come to my house at 7 o’clock tonight. I think Jeny, Ronny’s girlfriend,will
come too.
2. Untuk
menyatakan kembali kejadian/aktivitas yang direncanakan akan terjadi/dilakukan
pada saat tertentu di masa lampau.
Dengan menggunakan analogi pada kategori 1, kalimat
dalam simple future tense berikut:
1) Ronny is going
to come to my house at 7 o’clock tonight.
2) He has an appointment. He is going to meet his business partner at noon.
3) I am going
to go to the shopping. Do you want to go with me?
Seiring dengan berulirnya waktu akan dinyatakan
dalam past future tense menjadi:
1) Ronny was
going to come to my house at 7 p.m. two days ago but he couldn’t come
because of the pouring rain. Atau, Ronny would come to my house at 7 p.m. two
days ago but he couldn’t come because of the pouring rain.
2) He was
going to meet his business partner at noon two days ago but he suddenly got
sick
just half an hour before the meeting. Atau, He would
meet his business partner at noon two
days ago but he suddenly got sick just half an hour
before the meeting.
3) I was
going to go to the shopping mall when I asked whether you wanted to go with
me two
days ago. Atau, I would go to the shopping mall when
I asked whether you wanted to go with
me two days ago.
3. Untuk membuat
main clause unreal conditionals tipe 1, yaitu conditional yang faktanya dalam
simple present tense atau simple future tense.
Contoh :
1) If I were
you, I would study harder.
2) The crops would
not fail to produce if the rain fell.
3) They would
not need to lime the soil if it were
not acidic
4. Untuk membuat
kalimat tak langsung (indirect speech), jika kalimat langsungnya menggunakan
simple future tense.
Contoh :
1) My friend told
me that he would teach me.
2) An agronomist said that the soil would be
more productive if we fertilized it.
3) Dean made
an announcement that the final exams would
be started in two weeks.
5. Untuk membuat
request atau command menjadi lebih formal atau lebih sopan.
Note: would lebih formal/sopan dibandingkan
will.
1) Would
you turn down the TV volume, please! It’s too loud.
2) I didn’t go to school yesterday, so would you please lend me your note?
3) If you’re free, would you go to see a movie with me tonight?
Note : Untuk kalimat negative cukup menambahkan
“not” setelah would atau setelah was/were.
