There are some common expressions we use:
yesterday,

last week,
yesterday afternoon, etc
Most verbs ( + ed)
walk→walked play →played
Verbs ending in e (+d)
live →lived use →used
Verbs ending in a consonant (輔音) + y
(-y + ied) (consonant: p, t, r, etc)
cry →cried carry →carried
Short verbs ending in a vowel (元音) + a consonant (vowel: a, e, i, o, u)
(double the consonant + y)
stop →stoppedshop →shopped
No change
cost →costput →put
Change the vowel (元音) or the consonant (輔音)
come →camering →rang
make →madesit →sat
Change the whole word

We add “did not” before the main verb to
form negative sentence. (did not = didn’t)
