TIP
We often use these time expressions when we talk about the past.
ago just now yesterday the day before yesterday
yesterday morning / afternoon / evening
last night / week / month / year
We form the simple past tense by adding -ed to regular verbs.
Most verbs +ed walk → walked
Verbs ending in -e +d live → lived
Verbs ending in a consonant+y -y+ied cry → cried
Short verbs ending in a vowel +a consonant double the consonant +ed stop →stopped
TIP
Verbs ending in a vowel+y form the simple past tense by adding -ed.
stay→stayed
We form the simple past tense of irregular verbs differently. We do not add -ed.
No change cost → cost
put → put
Change the vowel write → wrote
know → knew
Change the consonant make → made
spend → spent
Change the vowel(s) and the consonant(s) leave → left
teach → taught
Others is → was
am → was
are → were
have → had
TIP
Turn to pages 106 and 107 for more changes of irregular verbs.
