J. PENGGUNAAN WHEN DAN IF

When dan if tidak selalu sama.

When

If

Digunakan ketika sesuatu masih merupakan kemungkinan.

If I arrive home early, I will call you.

K. KESALAHAN YANG SERING TERJADI

1. Menggunakan “will” setelah if pada First Conditional

❌ If I will study, I will pass.

✅ If I study, I will pass.

Penjelasan

Setelah if, dalam First Conditional biasanya digunakan Simple Present, bukan will.


2. Salah menggunakan V2

❌ If I will have money, I would buy a car.

✅ If I had money, I would buy a car.

Karena ini Second Conditional:

If + V2 → would + V1


3. Salah menggunakan V2 setelah would

❌ I would went.

✅ I would go.

Setelah would, gunakan:

V1

Contoh:

would go
would study
would buy
would help


4. Salah menggunakan V2 setelah had

❌ If I had went…

✅ If I had gone…

Setelah had, gunakan V3.

Contoh:

V1 V2 V3
go went gone
eat ate eaten
see saw seen
take took taken
write wrote written
buy bought bought

L. CARA MUDAH MEMBEDAKAN CONDITIONAL

ZERO

Fakta / selalu benar

If + V1 → V1

FIRST

Mungkin terjadi

If + V1 → will + V1

SECOND

Khayalan / tidak nyata sekarang
