Conditional sentences

1.    There are three kinds of conditional sentences

b.    Type 2 (improbable condition)

c.    Type 3 (impossible condition)

Conditional sentences have two parts :

a.    If.clause

b.    Main.clause

Rumus :

Probable condition : if S + V1 s/es , S + will + V1 + O

Improbable condition : if S + V2 , S + would + V1 + O

Impossible condition : if S + had + V3 , S + would + have + V3 + O

Note :

Jika “S” orang ketiga tunggal, maka menggunakan s pada verb 1

2.    Type 1 (probable condition)

It means that it is probable that the action in the if.clause happens.

Observe the following example :

3.    Type 2 (improbable condition)

This type states that the action in the if.clause is improbable observe the following example :

If I had enough money, I would buy that book.

It is improbable for me to buy that book.

Note :

The verb in the if.clause is in the past tense, the verb in the main.clause is in the conditional tense.

(tipe kedua menyatakan bahwa kegiatan dalam if clause tidak mungkin terjadi saat ini, oleh karena itu kondisi dalam main clause tidak dapat terpengaruhi)

4.    Type 3 (impossible condition)

This is type indicates that the action in the if.clause did not happen in the past, so the condition cannot be fulfilled.

(tipe ketiga menunjukkan bahwa kegiatan dalam if.clause tidak dapat terjadi pada waktu lampau, oleh karena itu kondisi dalam main.clause mustahil terpenuhi)
