What is the Past Simple and When Do We Use It?
The Past Simple tense describes actions or events that happened at a specific time in the past and are now finished. It’s like telling a story about something that is already over.
We use the Past Simple for:
- Completed actions in the past: She finished her homework an hour ago.
- A series of completed actions: He woke up, ate breakfast, and left for work.
- Past habits or routines: When I was a child, I played outside every day.
Common time expressions used with the Past Simple include:
- Yesterday
- Last week/month/year
- Two days ago
- In 2020
- When I was young
How Do We Form the Past Simple? (Regular Verbs)
Most verbs in English are regular. To form the Past Simple for these verbs, we simply add -ed to the base form of the verb.
- Walk → walked
- Play → played
- Start → started
There are a few spelling rules to remember:
- Verbs ending in -e: Add only -d. Live → lived, Arrive → arrived.
- Verbs ending in consonant + -y: Change -y to -i and add -ed. Study → studied, Try → tried.
- Verbs ending in vowel + -y: Just add -ed. Play → played, Enjoy → enjoyed.
- Verbs ending in CVC (consonant-vowel-consonant) with a stressed short vowel: Double the last consonant and add -ed. Stop → stopped, Plan → planned.
What About Irregular Verbs?
Many common verbs in English are irregular. This means they do not follow the -ed rule for the Past Simple. Their forms change in different ways.
You need to learn these irregular verbs by heart. There are no simple rules for them, but many are used very often.
- Go → went
- See → saw
- Have → had
- Eat → ate
- Read → read (same spelling, different pronunciation)
The more you read and listen to English, the easier it will be to remember these forms.
How Do We Make Questions and Negatives in the Past Simple?
To make questions and negative sentences in the Past Simple, we use the auxiliary verb did （或 didn't for negatives) and the base form of the main verb.
- Positive: I played football yesterday.
- Negative: I didn't play football yesterday. (NOT I didn't played)
- Question: Did you play football yesterday? (NOT Did you played)
Remember, the main verb always returns to its base form after did 或 didn't.
| Base Form | Past Simple |
|---|---|
| be | was / were |
| go | went |
| see | saw |
| have | had |
| do | did |
| eat | ate |
| read | read |
| take | took |
| begin | began |
示例
- We visited London last summer.
- She didn't like the movie.
- Did you finish your homework?
- They went to the beach two days ago.
- I saw my friend at the park.
- He didn't eat breakfast this morning.

西班牙语母语者常犯的错误
Spanish speakers sometimes make specific mistakes with the Past Simple:
- 使用 was/were with main verbs: Do not say I was went to the shop. The correct form is I went to the shop. Remember, was/were is only for the verb 'to be' or continuous tenses.
- Not using the base form after did/didn't: 错误： Did you saw him? 正确： Did you see him? The auxiliary did carries the past tense, so the main verb stays in its base form.
- Confusing regular and irregular verbs: Avoid saying I goed to the party. The correct irregular form is I went to the party.
- Over-using the Past Simple for actions that continue: If an action started in the past and continues now, use the Present Perfect, not the Past Simple. Incorrect: I lived here for five years (and I still live here). 正确： I have lived here for five years.
