Tenses: Present, Past and Future

🟢 Lite — Quick Review (1h–1d)

Rapid summary for last-minute revision before your exam.

A tense is the verb form that locates an action or state in time relative to the moment of speaking. English has three time frames — Present, Past, Future — and four aspects (Simple, Continuous/Progressive, Perfect, Perfect Continuous), producing 12 tense forms in total. The auxiliary verb (am/is/are, was/were, have/has, had, will, shall) does the time-marking; the main verb carries the meaning.

Simple Present = habit/truth: The sun rises in the east.
Past forms need V2 (regular) or irregular past forms: She went / They ate.
Perfect tenses combine have/has/had + V3 (past participle): I have written the letter.
Continuous tenses add verb-ing after the auxiliary: They were playing when it rained.

Standard content for students with a few days to months.

The Three Tense Groups and Their Four Aspects

Each of the three time frames (Present, Past, Future) carries four aspects, giving 12 forms. Knowing the structure makes gap-fill and “choose the correct option” items mechanical.

Aspect	Form	Function
Simple	base verb / V2 / will + base	Habit, fact, completed action, prediction
Continuous	be + verb-ing	Action in progress at a stated time
Perfect	have + V3	Action completed before a reference point
Perfect Continuous	have + been + verb-ing	Duration of an action up to a reference point

Time-Marker Cues for NCEE

Examiners test recognition by planting adverbs and adverbials. Identify the marker first, then select the tense.

Simple Present: always, usually, often, every day, twice a week
Present Continuous: now, at the moment, right now, Look!
Present Perfect: just, ever, never, already, yet, since, for, recently, so far
Simple Past: yesterday, ago, last week/month/year, in 2020, when I was young
Past Continuous: while, when + past action, at 8 o’clock yesterday
Past Perfect: before, after, by the time, already (in past narrative)
Future forms: tomorrow, next week, in 2030, by next year, by the time

Trap alert: since (point of time) pairs with Perfect Continuous, but for (duration) can pair with both Perfect and Perfect Continuous depending on whether duration or completion is emphasised.

High-Yield Distinctions Tested in NCEE Objective Items

Simple Past vs. Present Perfect: I have seen him yesterday is wrong because yesterday is a finished-time adverb that demands Simple Past (I saw him yesterday). Conversely, I have known her for ten years is correct while I knew her for ten years implies the knowing ended.
will vs. be going to: will = spontaneous decision, prediction based on opinion (It will rain tonight); be going to = pre-existing plan or evidence-based prediction (Look at those clouds — it is going to rain).
Past Simple vs. Past Continuous: A longer background action takes the Past Continuous; the shorter interrupting action takes the Simple Past (I was reading when the phone rang).

Common Errors in Candidate Scripts

Error	Wrong	Correct
Past participle confusion	I have broke it	I have broken it
Subject-verb agreement	He go to school	He goes to school
Wrong aspect in past narrative	While she was cooked, the bell rang	While she was cooking, the bell rang
Double auxiliary	He will can come	He will be able to come

Worked Example

By the time the match ______ (start), the crowd ______ (wait) for an hour.

Answer: starts … will have been waiting. The first blank is a present-tense subordinate clause triggered by by the time + future reference; the second is Future Perfect Continuous because the waiting extends up to a future point.

Practice Prompts

Fill in: She ______ (read) this novel since Monday. (Expected: has been reading — duration marker since + ongoing action.)
Identify the tense and rewrite in Simple Past: They have been building the bridge for two years. (Expected: They built the bridge / They were building the bridge for two years — though the continuous nuance is lost.)
