PERFECT TENSES
PRESENT PERFECT
We make present perfect verbs with have/has + past participle (worked, seen, known): I have worked in a bank for ten years. She has broken a cup.
Verbs ending in –y:
- vowel (a, e, o) + -y= yed (played, enjoyed)
- consonant (d,l,r..)+ -y = ied (tried, studied)
Doubling:
- one vowel + one consonant: stop- stopped
- two vowels- don't double: seem- seemed
- two consonants- don't double: want-wanted
- double in stressed syllables: preFER- preffered
- Irregular verbs have a special form: eaten, made, forgotten
