1. Simple Past Tense

The Simple Past Tense is one of the most commonly used English tenses. We use it to talk about actions, events, or situations that started and finished in the past.

Main Use of the Simple Past

Use the Simple Past when an action was completed at a particular time in the past.

Examples:

• I visited Angkor Wat five years ago.
• She went to school yesterday.
• We watched a movie last night.
• Tom finished his homework two hours ago.
• They traveled to Phnom Penh last month.

The action is finished, and the time is either stated or understood.

Common Time Expressions

The Simple Past is often used with past-time expressions such as:

• yesterday
• yesterday morning
• last night
• last week
• last month
• last year
• two days ago
• five years ago
• a minute ago
• in 2000
• in April
• in the 1990s

Simple Past Formula

Positive:

Subject + past verb (V2) + ...

• I visited my friend yesterday.
• She studied English last night.
• They went to the market.

For regular verbs, we usually add -ed:

• work → worked
• play → played
• visit → visited

Some verbs are irregular:

• go → went
• eat → ate
• drink → drank
• see → saw
• take → took

Negative Form

Subject + did not (didn't) + base verb

• She didn't go to school yesterday.
• I didn't watch television last night.
• They didn't finish their homework.

Important: After didn't, use the base form of the verb.

Incorrect: She didn't went to school.
Correct: She didn't go to school.

Yes/No Questions

Did + subject + base verb...?

• Did you watch TV last night?
• Did she visit her grandmother?
• Did they finish the project?

WH-Questions

WH-word + did + subject + base verb...?

• What did you do yesterday?
• Where did you go last weekend?
• When did she arrive?
• Why did they leave early?

Example Analysis

I drank a cup of coffee this morning.

The verb drank is in the Simple Past. The action happened and finished in the past.

Simple Past for a Series of Actions

We can also use the Simple Past to describe several completed actions that happened one after another.

This morning, I got up at 5:30. Then, I brushed my teeth, took a shower, ate breakfast, and went to school.

All the actions happened in sequence and were completed in the past.

---

2. Past Continuous Tense

The Past Continuous Tense describes an action that was happening or was in progress at a particular time in the past.

It is especially useful when we want to show what was happening around a specific moment.

Main Uses of the Past Continuous

There are several common situations in which we use the Past Continuous.

Use 1: An Action in Progress at a Specific Past Time

Use the Past Continuous for an action that was happening at a particular moment in the past.

Examples:

• Roza was doing her homework at 9:00 last night.
• They were playing soccer at 2:00 yesterday afternoon.
• I was studying English at 7:30 last night.
• My mother was cooking dinner at 6:00 p.m.

The focus is on the action in progress, rather than simply saying that it happened.

Use 2: Two or More Actions Happening at the Same Time

We can use the Past Continuous when several actions were happening simultaneously.

When I got up this morning, my mom was cooking breakfast, my dad was exercising, my brother was taking a shower, and the birds were singing.

Several actions were in progress at approximately the same time.

Use 3: An Interrupted Action

The Past Continuous and Simple Past are often used together when one action interrupts another.

The Past Continuous describes the longer action that was already happening.

The Simple Past describes the shorter action or event that happened during it.

Examples:

• I was sleeping when the phone rang.
• She was cooking when her friend arrived.
• We were watching TV when the electricity went out.
• While the teacher was writing on the whiteboard, his marker fell.

A useful pattern is:

Past Continuous + when + Simple Past

or

While + Past Continuous, Simple Past

Past Continuous Formula

Positive:

Subject + was/were + V-ing

• I was sleeping at 11:00 last night.
• She was studying English.
• They were playing soccer.

Use:

• was with I, he, she, and it
• were with you, we, and they

Negative Form

Subject + was not/were not + V-ing

• I wasn't sleeping.
• She wasn't studying.
• They weren't playing soccer at this time yesterday.

Yes/No Questions

Was/Were + subject + V-ing...?

• Was your dad watching TV at nine last night?
• Were they playing soccer?
• Was she studying English?

WH-Questions

WH-word + was/were + subject + V-ing...?

• What was your mom doing at 6:00 this morning?
• Where were they going?
• Why was he crying?

3. Past Perfect Tense

The Past Perfect Tense is used when we are talking about the past and want to show that one action happened before another past action or before a particular time in the past.

Think of it as the earlier past.

Main Use of the Past Perfect

Use the Past Perfect for the action that happened first.

She had locked the door before she left her house.

There are two past actions:

1. She had locked the door. → happened first
2. She left the house. → happened later

The Past Perfect makes the order of events clear.

More Examples

• I had finished my homework before I went to bed.
• They had eaten dinner before the guests arrived.
• She had already left when I called her.
• Tom had completed his university degree before 2005.

Quick Rule

When two past events are connected:

Past Perfect = action that happened first

Simple Past = action that happened later

For example:

When I arrived at the station, the train had already left.

The train left first.
I arrived second.

Past Perfect Formula

Positive:

Subject + had + past participle (V3)

• I had done my homework before I went to bed.
• She had finished her work.
• They had already eaten.

The word had is used with all subjects:

• I had
• You had
• He had
• She had
• It had
• We had
• They had

Negative Form

Subject + had not (hadn't) + past participle (V3)

• She hadn't watered the plants before she went to school.
• I hadn't finished my homework.
• They hadn't eaten before the meeting.

Yes/No Questions

Had + subject + past participle (V3)?

• Had you informed her before you visited her?
• Had she finished her homework?
• Had they already left?

WH-Questions

WH-word + had + subject + past participle (V3)?

• What had you done before you left?
• Where had she gone?
• Why had they left early?

4. Past Perfect Continuous Tense

The Past Perfect Continuous Tense describes an action that had been continuing for a period of time before another event or point in the past.

This tense focuses particularly on the duration or ongoing nature of the action.

Main Use of the Past Perfect Continuous

Use it when an activity continued for some time before another past event.

Examples:

• She had been studying for three hours before she went to bed.
• They had been practicing for weeks before the competition.
• I had been waiting for thirty minutes before the bus arrived.
• Roza had been exercising regularly before she became fit and healthy.

The important idea is that the action was ongoing for a period of time before another past event.

Using "For" and "Since"

The Past Perfect Continuous is commonly used with for and since to show duration.

For + period of time

• for two hours
• for three days
• for several weeks
• for many years

Example:

I had been studying for two hours before my friend called.

Since + starting point

• since Monday
• since morning
• since 2020
• since 8:00

Example:

She had been working there since 2020 before she moved to another city.

Past Perfect Continuous Formula

Positive:

Subject + had been + V-ing

• They had been practicing before the match.
• I had been studying for two hours.
• She had been working all morning.

The structure is the same for every subject:

I/You/He/She/It/We/They + had been + V-ing

Negative Form

Subject + had not (hadn't) been + V-ing

• I hadn't been doing anything before I went to bed.
• She hadn't been sleeping well.
• They hadn't been practicing regularly.

Yes/No Questions

Had + subject + been + V-ing?

• Had they been practicing before the match?
• Had she been working all day?
• Had you been waiting for a long time?

WH-Questions

WH-word + had + subject + been + V-ing?

• What had you been doing before you went to bed?
• Where had they been working?
• Why had she been crying?

Simple Past vs. Past Continuous

One of the most important differences to understand is between the Simple Past and Past Continuous.

Simple Past

Use it for a completed action.

I watched TV last night.

The action is viewed as completed.

Past Continuous

Use it for an action that was in progress at a particular past moment.

I was watching TV at 8:00 last night.

The focus is on the action in progress at that specific time.

Compare:

I cooked dinner last night.

This tells us about a completed activity.

I was cooking dinner when my brother arrived.

This shows that cooking was already in progress when another event occurred.

---

Past Perfect vs. Simple Past

The main difference is the order of two past events.

When I arrived, John left.

Depending on context, this can mean John left around the time I arrived.

But:

When I arrived, John had left.

This clearly tells us that John left before I arrived.

Remember:

Past Perfect → earlier past action

Simple Past → later past action

---

Past Perfect vs. Past Perfect Continuous

These two tenses can sometimes look similar, but they emphasize different things.

Past Perfect

Focuses on the completion or result of an action.

She had written three pages before dinner.

The focus is on the completed result: three pages.

Past Perfect Continuous

Focuses on the duration or ongoing activity.

She had been writing for two hours before dinner.

The focus is on how long the activity had continued.

Common Mistakes with Past Tenses

English learners often make a few common mistakes when using past tenses.

Mistake 1: Using V2 after "didn't"

❌ She didn't went to school.

✅ She didn't go to school.

After didn't, always use the base form of the verb.

Mistake 2: Using "did" with the Past Perfect

❌ Did you had finished your homework?

✅ Had you finished your homework?

The Past Perfect uses had, not did.

Mistake 3: Forgetting "been" in the Past Perfect Continuous

❌ I had studying for two hours.

✅ I had been studying for two hours.

The correct structure is:

had + been + V-ing

Mistake 4: Confusing "was" and "were"

❌ They was playing football.

✅ They were playing football.

Use was with I/he/she/it and were with you/we/they.
