What is a Past Participle?
A past participle is a form of a verb. It is used in different ways in English grammar.
For regular verbs, the past participle looks the same as the simple past form. You just add -ed to the base verb.
- work → worked
- finish → finished
- play → played
What Makes Irregular Past Participles Different?
Irregular verbs do not follow the -ed rule for their past participle form. They have special forms that you need to learn by heart.
These forms can be very different from the base verb or the simple past verb.
- eat (base) → ate (simple past) → eaten (past participle)
- go (base) → went (simple past) → gone (past participle)
- see (base) → saw (simple past) → seen (past participle)
When Do We Use Irregular Past Participles?
Irregular past participles are very important. We use them in several common grammar structures:
In Perfect Tenses
We use past participles with have, has, 或 had to form perfect tenses. The most common is the Present Perfect.
- I have never seen that movie.
- She has written many books.
- They had already eaten when I arrived.
In the Passive Voice
We use past participles with forms of the verb to be (is, are, was, were) to make passive sentences.
- The window was broken by the ball.
- English is spoken all over the world.
- These shoes were made in Italy.
As Adjectives
Sometimes, a past participle can act like an adjective to describe a noun.
- I found a broken chair. (The chair is broken.)
- He likes fried chicken. (The chicken is fried.)
- The stolen car was found. (The car was stolen.)
| Base Form | Simple Past | Past Participle |
|---|---|---|
| be | was/were | been |
| break | broke | broken |
| come | came | come |
| do | did | done |
| eat | ate | eaten |
| go | went | gone |
| have | had | had |
| make | made | made |
| read | read | read |
| see | saw | seen |
| speak | spoke | spoken |
| write | wrote | written |
示例
- Have you ever flown in an airplane?
- My keys have been taken.
- She has read that book three times.
- The song was sung beautifully.
- I haven’t eaten breakfast yet.

常见问题
What is the difference between the simple past and the past participle?
"(《世界人权宣言》) simple past describes an action that finished in the past (e.g., I ate pizza yesterday.). The past participle is a verb form used with auxiliary verbs like have 或 be to form perfect tenses or the passive voice (e.g., I have eaten pizza. 或 Pizza was eaten.).
How can I learn irregular past participles?
The best way is to learn them in groups or categories, practice using them in sentences, and review them regularly. Many people find it helpful to memorize the three forms together: base form – simple past – past participle (e.g., go – went – gone).
Why are they called ‘irregular’?
They are called ‘irregular’ because their past participle form does not follow the standard rule of adding -ed to the base verb. Each irregular verb has its own unique form, or sometimes the form is the same as the base or simple past, but not with -ed.
What kind of exercise helps with irregular past participles?
Exercises like ‘Drag the Words’ or ‘Multiple Choice’ where you select the correct past participle form for a given sentence are very effective. They help you practice recognizing and using the correct forms in context.
