What you'll learn
Tense consistency and the correct use of verb forms are essential to clear, accurate writing and are tested throughout the CSEC English A examination — in Paper 1 multiple-choice items and in the expression marks for every piece of Paper 2 writing. Tense tells the reader when an action happens; consistency means not switching between past, present and future without reason. In this guide you will learn the main tenses, how to keep tense consistent within a passage, how to choose the correct verb form (including irregular verbs and participles), and when a deliberate change of tense is correct. Strong control of tense makes your narratives, reports and letters read fluently and prevents a common, easily avoided error.
Key terms and definitions
Tense — the form of a verb showing the time of an action (past, present, future).
Tense consistency — keeping the same tense throughout a passage unless the meaning requires a change.
Regular verb — a verb forming its past tense with -ed (walk → walked).
Irregular verb — a verb with an unpredictable past form (go → went, write → wrote).
Participle — a verb form used with helpers: present participle (-ing) and past participle (written, gone).
Auxiliary (helping) verb — a verb such as have, has, had, is, was, used to form tenses.
Core concepts
The main tenses
The present tense describes what happens now or generally ("She writes every day"). The past tense describes what already happened ("She wrote yesterday"). The future tense describes what will happen ("She will write tomorrow"). Each also has continuous forms (is writing, was writing) for ongoing actions and perfect forms (has written, had written) for completed actions linked to another time.
Keeping tense consistent
Within a single passage, choose a main tense and stay in it. If you begin a story in the past tense, continue in the past: "She walked to the market and bought mangoes," not "She walked to the market and buys mangoes." Unnecessary shifts confuse the reader about the order of events and are penalised in expression marks.
When a change of tense is correct
Tense should change when the time genuinely changes. A narrative set in the past may include a general truth in the present ("She realised that water boils at 100°C"), or refer forward to the future ("She knew she would return"). The test is meaning: change tense only when the timing of the action actually differs.
Correct verb forms: regular and irregular
Regular verbs add -ed for the past (jump → jumped). Irregular verbs must be learned individually (begin → began → begun; see → saw → seen; bring → brought → brought). A frequent error is mixing the simple past with the past participle: "I saw him" (simple past) versus "I have seen him" (participle with have). Never write "I have saw" or "I seen him."
Participles and auxiliaries
The past participle is used with have/has/had (perfect tenses) and in the passive voice (the letter was written). The present participle (-ing) is used with is/was/are/were for continuous tenses (she is reading). Choosing the right participle and the right auxiliary keeps the tense correct.
Sequence of tenses in reported speech
When you report what someone said, the tense usually shifts back: "I am tired" becomes "She said she was tired." Keeping this sequence consistent is important in summaries and comprehension answers.
Worked examples
Example 1: Fixing an inconsistent shift (Paper 2 expression)
Correct: "As the rain fell, the children run for shelter and were laughing."
The passage is in the past tense, so run should be ran: "As the rain fell, the children ran for shelter and were laughing." All verbs now sit in the past.
Example 2: Simple past vs past participle (Paper 1 style)
Choose the correct form: "By the time we arrived, the bus had already (went / gone)."
The auxiliary had requires the past participle, which is gone. So: "…the bus had already gone." ("Went" is the simple past and cannot follow had.)
Example 3: Justified tense change (Paper 2)
Explain why this sentence is correct: "The teacher explained that the Earth orbits the Sun."
The reporting verb explained is past, but orbits is present because it states a general scientific truth that is always true. The change of tense is meaningful and therefore correct.
Common mistakes and how to avoid them
Drifting between past and present. Decide on a main tense before you write and keep to it; check by skimming your verbs at the end.
"Have saw / had went / I seen". With have/has/had use the past participle (seen, gone, done), never the simple past or the bare verb.
Confusing -ing and -ed forms. Use -ing with is/was (continuous) and the past participle with have/has/had (perfect).
Changing tense for no reason. Only switch when the timing of the action genuinely differs.
Forgetting the tense shift in reported speech. "She said she was coming," not "She said she is coming."
Exam technique for Tense Consistency
Choose a dominant tense. Narratives are usually in the past; reports and articles often in the present. Set it early and hold it.
Learn the key irregular verbs. Memorise the three forms (begin/began/begun, etc.) so participles come automatically.
Match auxiliary to participle. have/has/had → past participle; is/was → -ing form.
Proofread your verbs. In Paper 2, a final pass checking only the verbs catches most tense slips quickly.
Justify any change. If you switch tense, be sure the time really changes; otherwise correct it.
Quick revision summary
Tense shows when an action happens — present, past or future — with continuous (-ing) and perfect (have/had + participle) forms for ongoing and completed actions. Tense consistency means choosing a main tense and keeping it throughout a passage; a story begun in the past stays in the past. Change tense only when the timing genuinely changes, such as stating a general truth in the present or referring to the future. Use the correct verb forms: regular verbs add -ed, while irregular verbs (go/went/gone, see/saw/seen) must be learned. Crucially, use the past participle (not the simple past) after have/has/had and in the passive — "I have seen", never "I have saw" — and use the -ing form after is/was. In reported speech, shift the tense back ("She said she was tired"). Choose a dominant tense, master the irregular verbs, match auxiliaries to participles, and proofread your verbs to secure expression marks.
