1. Thì hiện tại đơn

- Vbare:

( + ) S + V (s/es) + O

( - ) S + don't/ doesn't + Vbare + O

( ? ) Do/Does + S + Vbare + O?

- Tobe:

( + ) S + am/is/are + O

( - ) S + am/is/are + not + O

( ? ) Am/ Is/ Are + S + O

2. Thì hiện tại tiếp diễn

( + )  S + am/is/are + V_ing + O

( - )  S + am/is/are + not + V_ing + O

( ? )  Am/ Is/ Are + S + V_ing + O?

3. Thì quá khứ đơn

- Vbare:

( + ) S + was/ were + O

( - ) S + was/ were + not + O

( ? ) Was/ Were + S + O?
- Tobe:

( + ) S + PII/ed + O

( - ) S + didn't + Vbare + O

( ? ) Did + S + Vbare + O ?

4. Thì tương lai hoàn thành

( + ) S + will + have been + V_ing + O

( - ) S + won't+ have been + V_ing + O

( ? ) Will + S+ have been + V_ing + O?
