Tenses and Their Usage — JAMB English Study Guide

Present tense uses:

• Present simple: permanent situations, scientific facts, habits, scheduled future events (“The train leaves at 6pm”)
• Present continuous: actions happening now, temporary arrangements, changing situations, with always for annoyance/praise (“He is always complaining”)
• Present perfect: past actions with present results, life experiences, ongoing situations starting in past (“I have lost my keys” = can’t find them now)
• Present perfect continuous: emphasis on duration of ongoing action (“I have been waiting for 2 hours”)

Past tense uses:

• Past simple: completed actions in specific past time (“Yesterday, I went to Lagos”)
• Past continuous: actions in progress at specific past time, or two simultaneous past actions (“I was sleeping when she called”)
• Past perfect: action completed before another past action (“By the time I arrived, she had left”)
• Past perfect continuous: continuous action leading up to past event (“She had been studying for 3 hours when the lights went out”)

Future tense uses:

• Future simple (will): instant decisions, predictions, promises, facts (“It will rain tomorrow”)
• Future continuous: actions in progress at specific future time (“I will be travelling this time tomorrow”)
• Future perfect: action completed by specific future time (“By 2027, I will have graduated”)
• Future perfect continuous: continuous action up to future point (“By June, I will have been working here for 5 years”)

Time expressions:

Time expression	Tense commonly used
yesterday, last week, in 2020	past simple
ago	past simple (with “had” for past perfect)
now, at the moment, currently	present continuous
today, this week	any appropriate tense depending on context
for, since, recently, lately	present perfect
yet, already, just	present perfect
tomorrow, next week, in the future	future simple

Common JAMB mistakes: Using “since” with duration (“since 5 years” — wrong; should be “for 5 years”); using past tense with “this is the first time”; confusing present perfect and past simple when time reference is given.

Tenses and Their Usage — Comprehensive Notes

Advanced tense distinctions:

Present perfect vs Past simple: Use past simple when specific time is given (yesterday, last week, in 2020). Use present perfect when no specific time is given, or when time period is not finished (this year, recently). “I have read that book” (general experience, no specific time) “I read that book yesterday” (specific past time) “I have been to London” (experience, not completed action) “I went to London last year” (completed past action)

Past perfect vs Past simple: Past simple: both actions happened and are presented as equally in the past. Past perfect: one action (the one with past perfect) happened BEFORE the other. “I bought a new car” (both past, no sequence emphasised) “I had bought a new car before I lost my old one” (buying happened first)

Sequence of tenses (subject-verb agreement in clauses): Main clause in present → dependent clause can be any tense that makes sense. Main clause in past → dependent clause typically in past (but would/could/might remain unchanged). “He said he was coming” (not “he is coming”) “She said she will go” → acceptable only if futurity cannot be expressed otherwise.

Conditional sentences: Type 0 (general truth): If + present simple, present simple (“If you heat water, it boils”) Type 1 (real possibility): If + present simple, will + verb (“If it rains, I will stay home”) Type 2 (unreal/imagined): If + past simple, would + verb (“If I had money, I would travel”) Type 3 (past unreal): If + past perfect, would have + past participle (“If I had studied, I would have passed”)

Wishes: Wish + past simple (present unreal): “I wish I knew the answer” Wish + past perfect (past unreal): “I wish I had studied harder” Wish + would (annoyance about stubbornness): “I wish you would stop interrupting”

JAMB exam patterns:

• 2023 JAMB: Choose the correct: “By next month, she ___ in this company for 10 years”

• 2021 JAMB: Select the option that expresses past perfect tense
• 2020 JAMB: Identify the error: “I have seen him yesterday”

Key time markers:

• since (point in time): since 2010, since Monday, since I was a child
• for (duration): for 5 years, for a long time, for two hours
• ago (past marker): 5 years ago, long ago
• before (earlier past): before the lesson, I had left before
• after (later past): after the lesson, I left after eating
