Unit 36. Regular and irregular verbs
- Past Simple and Past Participle
clean → cleaned live → lived paint → painted
Past Simple (see Unit 9):
I cleaned my shoes yesterday.
Charlie studied engineering at university.
We use the Past Participle for the Present Perfect and the Passive.
Present Perfect = have/has + Past Participle (see Unit 15, see Unit 16, see Unit 17):
- I have cleaned my shoes.
- Joan has lived in London for ten years.
Passive = be (am/is/are/was/were) + Past Participle (see Unit 20):
- These rooms are cleaned every day.
- My car was repaired last week.
- Irregular verbs
Sometimes the Past Simple and Past Participle are the same. For example:
- I made a cake yesterday. (Past Simple)
- I have made some coffee. (Past Participle - Present Perfect)
- Butter is made from milk. (Past Participle - Present Passive)
Sometimes the past simple and past participle are different. For example:
- Somebody broke this window last night. (Past Simple)
- Somebody has broken this window. (Past Participle - Present Perfect)
- This window was broken last night. (Past Participle - Past Passive)
