Kiến thức cần nhớ:

Thì QKD:

(+) S + V2/ed + O

(-) S + did + not + V-inf

(?) Did + S + V-inf?

Thì QKTD:

(+) S + was/were + Ving

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

(?) Was/Were + S + Ving?

Thì QKHT:

(+) S + had + VpII

(-) S + had + not + VpII

(?) Had + S + VpII?

Hành động đang xảy ra thì có hành động khác cắt ngang

+ Hành động đang xảy ra `->` QKTD: S + was/were + Ving

+ Hành động cắt ngang `->` QKD: S + V2/ed

Hành động xảy ra trước 1 hành động khác trong QK

- Before + S + V2/ed, S + had + VpII: Trước khi
