English uses verb tenses to show when an action happens. The present tense describes actions happening now, the past tense refers to actions that have already happened, and the future tense indicates actions that will happen later. All three are used in everyday speech and writing and are part of the school syllabus.

Of the three, the past and present tenses are the ones most students often find difficult. It is not the concept that trips them up. Students generally understand that 'I eat' is present and 'I ate' is past. The difficulty lies in the four forms each tense takes and in knowing which form applies to a specific sentence.

The difference between an AL1 and an AL3 often comes down to mastering the four forms of each tense. The present perfect and the simple past, for instance, both refer to past actions but are not interchangeable, and confusing them is a common and heavily penalised error in the PSLE English examination.

Clear distinction between past and present tenses ensures accuracy, avoids mistakes, and improves clarity in communication.

What is Verb Tense and Why Does It Matter for Primary Students?

Verb tense signals when an action takes place by changing the form of the verb. A single verb can communicate whether something happened yesterday, is happening now, or has yet to occur, simply by how it is written.

For primary school students, getting tense right matters for several specific reasons:

• Meeting PSLE examination requirements: Tense and subject-verb agreement are among the most heavily tested grammar areas in the PSLE. Questions in grammar MCQs and editing regularly require students to identify the correct verb form based on the subject and the sentence's time frame.
• Ensuring clarity in communication: The correct tense indicates when events occur. Without it, the sequence of a story or the meaning of a sentence becomes unclear.
• Maintaining consistency in composition: Tense switching within a composition is one of the most common errors that markers flag. A narrative written in the past tense must remain in the same tense throughout.
• Avoiding common grammatical errors: Many students mix up regular and irregular verb forms, apply 's' or 'es' endings inconsistently in the present tense, or confuse tenses that look similar in structure.

The 8 Forms of Present and Past Tense at a Glance

A clear overview of the four forms within both present and past tenses provides a useful foundation for accurate usage.

What is the Present Tense?

The present tense describes actions or states that are happening now, that are generally true, or that are relevant to the current moment. It is the most commonly used tense in everyday communication and forms the foundation from which the other tenses can be understood by comparison.

There are four forms of the present tense, each used in a different context.

1. Simple Present Tense

The simple present tense describes actions that happen regularly, universal truths, or habits that occur on a consistent basis.

Signals: every day, always, usually, often, sometimes, never

How it is formed:

• For most subjects: base form of the verb. Example: 'I walk', 'They listen'.
• For third person singular (he, she, it): add 's' or 'es' to the base verb. Example: 'She walks', 'He watches'.

When to use it:

• Habits and routines: 'He brushes his teeth every morning.'
• General truths and facts: 'The Earth revolves around the Sun.'
• Permanent states: 'She lives in Tampines.'
• Instructions and directions: 'You turn left at the traffic light.'

The Trap: Forgetting the Third Person ‘s’

One of the most common errors is forgetting to add “s” or “es” for third person singular subjects. Writing “She walk to school” instead of “She walks to school” is a frequent mistake that can cost marks in the PSLE.

2. Present Continuous Tense

The present continuous tense describes an action that is in progress at the moment of speaking, or one that is happening around the current period of time.

Signals: now, at the moment, currently, at present, look!, listen!

How it is formed: am/is/are + -ing

• First person singular: 'I am reading.'
• Third person singular: 'She is cooking.'
• Plural subjects: 'They are practising.'

When to use it:

• Actions happening right now: 'He is writing a letter.'
• Ongoing actions around the present time: 'She is preparing for her examinations this month.'
• Planned future arrangements: 'We are visiting Grandma this weekend.'

The Trap: Using the Wrong ‘Be’ Verb or Missing ‘-ing’

Students often mix up “am”, “is”, and “are”, or forget to add “-ing” to the verb. Writing “She are cook” or “He is write a letter” instead of “She is cooking” and “He is writing a letter” are common errors that can lead to lost marks.

3. Present Perfect Tense

The present perfect tense describes an action that has been completed at some point before now, or an action that began in the past and continues into the present.

Signals: already, just, yet, ever, never, since, for, recently

How it is formed: has/have + past participle of the verb

• Third person singular: 'She has finished her homework.'
• All other subjects: 'They have visited the zoo.'

When to use it:

• Completed actions with no specific time mentioned: 'He has eaten breakfast.'
• Actions that started in the past and continue to the present: 'She has lived in Singapore for ten years.'
• Life experiences: 'They have never tried durian.'
• Recent actions with present relevance: 'I have just submitted my project.'

The Trap: Using It with Specific Past Time

Students often use the present perfect tense with specific past time markers like “yesterday” or “last week”. Writing “He has eaten breakfast yesterday” is incorrect. The present perfect should not be used with a definite past time, and the correct form would be “He ate breakfast yesterday.”

4. Present Perfect Continuous Tense

The present perfect continuous tense describes an action that began in the past, has been ongoing, and either continues into the present or has just recently stopped.

Signals: for, since, all morning, all week, how long

How it is formed: has/have been + verb-ing

• Third person singular: 'She has been studying for three hours.'
• Plural subjects: 'They have been waiting since morning.'

When to use it:

• Actions that started in the past and are still happening: 'He has been learning piano since Primary 1.'
• Actions that recently stopped but have a visible result: 'She has been crying; her eyes are red.'

The Trap: Confusing It with Present Perfect Tense

Students often confuse this tense with the present perfect tense. Writing “She has studied for three hours” instead of “She has been studying for three hours” changes the meaning. The continuous form emphasises the ongoing nature or duration of the action, which is often required in context.

What is the Past Tense?

The past tense describes actions, events, or states that have already occurred before the current moment. Like the present tense, it has four forms, each of which adds a different layer of meaning about whether the action was completed, ongoing, or connected to another past event.

1. Simple Past Tense

The simple past tense describes actions or events that were completed in the past.

Signals: yesterday, last week, ago, in 2020, at that time, then

How it is formed:

• Regular verbs: add 'ed' to the root form. 'Walk' becomes 'walked', 'listen' becomes 'listened'.
• Irregular verbs: the past tense form must be memorised individually. 'Go' becomes 'went', 'speak' becomes 'spoke', 'buy' becomes 'bought'.

When to use it:

• Completed actions at a specific time in the past: 'She visited her grandmother last Sunday.'
• A sequence of completed past actions: 'He woke up, got dressed, and ate breakfast.'
• Past habits or states no longer true: 'He walked to school when he was younger.'

The Trap: Using the Wrong Verb Form

Students often mix up regular and irregular verb forms or use the base form instead of the past tense. Writing “He go to school yesterday” instead of “He went to school yesterday” is a common error that can cost marks in the PSLE.

2. Past Continuous Tense

The past continuous tense describes an action that was in progress at a specific point in the past.

Signals: while, when, as, at that moment, at [specific time]

How it is formed: was/were + -ing

• Singular subjects: 'She was reading when the phone rang.'
• Plural subjects: 'They were playing football when it started to rain.'

When to use it:

• An ongoing action interrupted by another: 'I was doing my homework when Mum called me for dinner.'
• Two actions happening at the same time in the past: 'She was studying while he was sleeping.'
• Setting the scene in a story: 'The children were laughing, and the birds were singing.'

The Trap: Confusing It with Simple Past Tense

Students often use the simple past instead of the continuous form. Writing “I did my homework when Mum called” instead of “I was doing my homework when Mum called” loses the sense of an ongoing action being interrupted, which is required in such contexts.

3. Past Perfect Tense

The past perfect tense, sometimes called the pluperfect, describes an action that was completed before

another action in the past.

Signals: before, already, by the time, after, just, never (before another past event)

How it is formed: had + past participle of the verb

• 'He had already left by the time she arrived.'

When to use it:

• Showing that one past action happened before another: 'She had finished her revision before the examination began.'
• Reported speech referring to an earlier event: 'He said that he had never seen such heavy rain before.'

The Trap: Using It Without a Second Past Action

Students often use the past perfect tense on its own without a clear second past event. Writing “She had finished her homework” without any reference point can be incomplete in context. The past perfect should usually be used to show the sequence between two past actions.

4. Past Perfect Continuous Tense

The past perfect continuous tense describes an action that had been ongoing over a period of time in the past before another action occurred.

Signals: for, since, how long (before another past event), until, when

How it is formed: had been + verb-ing

• 'She had been waiting for two hours before the bus finally arrived.'

When to use it:

• An ongoing past action interrupted or completed by another: 'He had been practising for months before the competition.'
• Showing the duration of a past action: 'They had been travelling for six hours when they reached the campsite.'

The Trap: Confusing It with Past Perfect or Omitting Duration

Students often use the past perfect instead of the continuous form, losing the sense of duration. Writing “He had practised for months” instead of “He had been practising for months” removes the emphasis on the ongoing action. Another common mistake is omitting the time expression (e.g. “for” or “since”), which is key to showing duration in this tense.

Irregular Verbs in the Past Tense: A Key Challenge for Primary Students

Regular verbs follow a predictable pattern in the past tense: add 'ed' to the base form. Irregular verbs do not. Their past tense forms must be learned individually, and they appear frequently in both grammar questions and composition work.

Some irregular verbs change completely in the past tense. Others stay the same. A few change spelling but follow a recognisable pattern.

Some of the common irregular verbs include:

Notes: 'Read' looks identical in all three columns but is pronounced differently: the base form rhymes with 'feed', while the past tense rhymes with 'bed'. Also, the past participle is the form used after 'has/have/had' in perfect tenses. Students should memorise both the simple past and the past participle for each irregular verb, as both are tested.

Tense Questions from the 2025 PSLE English Paper

Practising previous PSLE questions is one of the most effective ways to build accuracy. Here are questions from the 2025 PSLE English Grammar MCQ paper that are directly relevant to the tenses.

Common Present and Past Tense Mistakes to Avoid

Understanding the rules of the past and present tense is one thing, and applying them under exam conditions is another. The following errors are commonly made by students in primary school English and are worth addressing directly.

• Tense switching mid-composition: This is the most common tense error in composition writing. A student begins a story in the past tense and then slips into the present tense mid-paragraph, often without noticing. Once a tense is chosen for a narrative, it must be maintained throughout. Before submitting, students should read their composition specifically to check that the main tense remains consistent from the first sentence to the last.
• Confusing simple past with present perfect: Simple past: 'She went to the library yesterday.' Present perfect: 'She has gone to the library.' The simple past tense is used when the time of the action is specified or implied. The present perfect is used when the exact time is not stated, and the focus is on the connection between the past action and the present moment. Students often use the simple past where the present perfect is required, particularly in grammar MCQs that contain words like 'just', 'already', or 'never'.
• Using the present tense for irregular verbs in past tense sentences: This is especially common for high-frequency irregular verbs. Students write 'He goes to school' instead of 'He went to school', or 'She comes home' instead of 'She came home'. The base form looks like the present tense, and students who are unsure of the irregular form sometimes default to it. Consistent practice with the irregular verbs table above significantly reduces this error.
• Misidentifying the height of the action: Students sometimes use the past continuous tense where the simple past is correct, and vice versa. The past continuous describes something ongoing. The simple past describes something completed. 'She was eating dinner when he called' is correct because eating was in progress when the call interrupted it. 'She ate dinner when he called' changes the meaning entirely: it implies she ate dinner in response to the call.
• Incorrect formation of the past perfect: Students sometimes omit 'had' and write 'She already finished before he arrived' instead of 'She had already finished before he arrived'. The 'had' is not optional; it signals the past perfect and indicates that one action preceded another.
