- Common mistakes ESL students make
- Simple practice examples with answers
When Do We Use the Simple Past Tense?
We use the past tense to talk about:
- a single action completed in the past
- a longer action completed in the past
- repeated actions completed in the past
A Single Action Completed in the Past
- I ate pizza last night.
- She made a cup of coffee at 7:00 am.
- We studied grammar at the library yesterday.
- The students turned in their homework on Monday.
A Longer Action Completed in the Past
- We stayed with my family for two weeks last December.
- I lived in Coyoacán last summer.
- The students spoke English with each other for two hours.
- The flight to Bogotá took four hours.
Repeated Actions Completed in the Past
- Alejandra cooked bacon and eggs three times last week.
- We visited Querétaro twice in 2018.
- The grammar class completed seven homework assignments.
- I played golf four times last week.
The Simple Past Tense: Affirmative Statements
We use affirmative statements in the simple past to say that an action happened and finished in the past.
Structure
Subject + past tense verb
The verb form is the same for all subjects.
Examples:
- I drank two cups of tea last night.
- She drank three cups of tea last night.
- Diego and I drank one cup of tea last night.
There is no auxiliary verb (do / does / did) in affirmative past statements
Do NOT add ‘did’ to affirmative past tense sentences.
❌ I did worked yesterday.
✅ I worked yesterday.
Why?
In affirmative sentences, the past time is shown by the past form of the main verb.
The auxiliary ‘did’ is only used in negatives and questions.
The Simple Past Tense: Negative Sentences
We use a negative sentence in the simple past to say that an action did not happen or was not true in the past.
Structure:
Subject + did not + base form of the verb
Examples:
- I didn’t work yesterday.
- He didn’t go to class.
- We didn’t travel to Mexico last summer.
Do NOT use the past form of the main verb after didn’t.
❌ We didn’t studied yesterday.
✅ We didn’t study yesterday.
Why?
The word ‘didn’t’ already shows past time, so the main verb must stay in the base form.
The Simple Past Tense: Questions
We use questions in the simple past to ask if an action happened or did not happen in the past.
Structure:
Did + subject + base form of the verb
Examples:
- Did you finish the homework?
- Did she call you last night?
- Did they arrive on time?
📌 The main verb always stays in the base form.
Do NOT use the past form of the main verb after did.
❌ Did Frida painted a picture yesterday?
✅ Did Frida paint a picture yesterday?
Why?
The word ‘did’ already shows past time, so the main verb must stay in its base form.
Spelling Rules in the Simple Past Tense
Before looking at the rules, remember:
Most regular verbs form the simple past by adding -ed to the base form of the verb, but small spelling changes are sometimes needed to make the word easier to read and pronounce.
Regular Verbs in the Simple Past Tense
Most Verbs in English verbs are regular.
1. For most regular verbs
Simply add -ed to the base form of the verb
| Base Form of the Verb | Past Tense |
| work | worked |
| play | played |
| watch | watched |
| clean | cleaned |
Most verbs form the past tense by adding -ed, but there are exceptions to this rule.
2. Regular Verbs Ending in -e
If a verb already ends in -e, add -d (not -ed).
- live → lived
- like → liked
- arrive → arrived
3. Regular Verbs Ending in Consonant + –y
If a verb ends in a consonant + y, change y to i, then add -ed.
- study → studied
- carry → carried
- try → tried
📌 If the verb ends in vowel + y, just add -ed:
- play → played
- enjoy → enjoyed
4. One-Syllable Regular Verbs Ending in a Consonant + Vowel + Consonant
If a one-syllable verb ends in:
- consonant + vowel + consonant
👉 double the final consonant and add -ed.
- stop → stopped
- plan → planned
- drop → dropped
Stress Rule
Some two-syllable verbs follow the same doubling rule only if the stress is on the final syllable.
- prefer → preferred
- admit → admitted
❌ studed → ✅ studied
❌ stoped → ✅ stopped
❌ planed → ✅ planned
❌ liveed → ✅ lived
Tip:
Always check the verb ending before adding -ed. Some verbs need a spelling change to make the past tense clear and easy to read.
Spelling the past tense is only part of the challenge. Regular verbs ending in -ed have three different pronunciations, depending on the final sound of the verb.

Irregular Verbs in the Simple Past Tense
Some verbs do not follow the -ed rule. These are called irregular verbs, and they must be memorized.
| Base Verb | Past Tense |
| go | went |
| eat | ate |
| see | saw |
| have | had |
| do | did |
📌 There is no rule for irregular verbs—practice and repetition are key.
