`2,` were you doing ( at this time yesterday - QKTD )

`3,` Did you go ( last night - QKĐ )

`4,` were you driving - happened

`5,` took - wasn't looking

`6,` didn't know - did

`7,` saw - was trying

`8,` was walking - heard - was following - started

`9,` wanted - changed ( Sự việc xảy ra nối tiếp nhau trong quá khứ ~ QKĐ )

`10,` dropped - was doing - wasn't broken

* Thì quá khứ đơn :

`( + )` S + V2/ed

`( - )` S + didn't + V (bare)

`( ? )` Did + S + V (bare) ?

* Thì quá khứ tiếp diễn :

`( + )` S + was/were + V-ing

`( - )` S + was/were + not + V-ing

`( ? )` Was/Were + S + V-ing ?

- Hành động đang xảy ra, hành động nền chia quá khứ tiếp diễn

- Hành động quá khứ xen vào chia quá khứ đơn
