I (Am/Was) (Do/Did) (Have/Had)
She/He/It (Is/was) (Does/Did) (has/Had)
We/You/They (Are/Were) (Do/Did) (Have/Had)

Semua Jenis Modals : Can/could, may/might, must, shall/should, will/would dapat digunakan untuk semua subject, kecuali Modal Shall khusus digunakan untuk Subject I dan We.

Dalam pemakainnya AV Sering disingkat misalnya He's (He Is) demikian untuk AV Not, misalkan isn't (Is Not), penyingkatan ini disebut dengan contraction. Contoh lain I'm (I am)
Tetapi jangan terkecoh, karena tidak semua contraction sama, sebagai contoh

She's belum tentu She Is, bisa juga She was, She Has tergantung tense kalimat sesudahnya.
Berikut ini Contraction yang biasa digunakan:
I'm = Iam
I'll = I Will
She's = She Is
You're = You Are
We've = We Have
The'y=They Would, The Had

Contoh membaca contraction:
He's a doctor : He Is karena Present Tense
He's sick yesterday : He was Karena Past Tense
She's been there : She has karena present perfect tense
