The Conditional Sentences ( If clause )

Dalam bahasa Indonesia, the conditional sentence adalah kalimat pengandaian. 

The conditional sentences have three type, it used for drawing the conditional, if can be put in the beginning sentence or after comma ( Kalimat pengandaian memiliki tiga tipe, itu digunakan untuk menggambarkan pengandaian, if bisa diletakkan pada awal kalimat atau setelah koma )

Type II ( Improbable Condition ) ( Pengandaian yang Tak Mungkin Terjadi )

The type II is the conditional sentences that impossible happen, used for the event in the present or future ( Tipe II adalah kalimat pengandaian yang tak mungkin terjadi, digunakan untuk peristiwa saat ini atau yang akan datang )

Formula

the real uses simple present tense so the conditional uses simple past tense and the real uses the positive sentence so the conditional uses simple the negative sentence and vice versa ( kenyataan menggunakan simple present tense maka pengandaian menggunakan simple past tense dan kenyataan menggunakan kalimat positif maka pengandaian menggunakan kalimat negatif dan begitu pula sebaliknya )
If + Subject + Simple Past Tense ( positive or negative ) ( special for tobe using were although i / she / he / it / person name ), Subject + modal ( should / would / could / might ) ( positive or negative )

Example

@ I am at home because tomorrow is holiday ( the real )
@ If tomorrow weren't holiday, i wouldn't be at home ( the conditional )
@ I ain't at home because tomorrow isn't holiday ( the real )
@ If tomorrow were holiday, i would be at home ( the conditional )
