8.3 Verb Tense, Voice, Agreement & Pronoun Reference

Word classes and clause types give you the skeleton of English. Verb tense, voice, agreement and pronoun reference put that skeleton in motion. ICAS Syntax items may ask which verb form fits a timeline, which sentence is grammatically consistent, or which rewrite removes an unclear they or this. Younger papers often focus on clear present/past choices and simple referents; upper papers add perfect and continuous forms, denser agreement traps, passive constructions and complex referencing across sentences. All passages and tables here are original practice content.

Verb Tense: Staging Events

Tense is not decoration. It tells the reader when something happens and whether it is complete, ongoing or connected to another time.

You do not need every advanced name for ICAS, but you do need to stage events so the order is clear.

Sequencing with perfect forms (original mini-passage)

By the time the judges arrived, the team had stacked the models on the display table. Now the room is quiet, and everyone waits.

• had stacked — completed before the judges arrived (past perfect)
• arrived — later past event (simple past)
• is / waits — present scene (simple present)

Unmotivated tense shift is a common error option: By the time the judges arrived, the team stacks the models… mixes past time signal with present verb without a reason.

Continuous vs simple

• She wrote letters all morning. (whole past activity as a unit)
• She was writing a letter when the courier knocked. (in-progress background)

Choose continuous when the stem emphasises interruption or ongoing action; choose simple when the event is complete or habitual.

Subject–Verb Agreement

The verb must agree with its subject in number (and, for be, person).

Traps that hide the real subject

1. Intervening phrases: The basket of apples is heavy. (subject = basket, not apples)
2. Relative clause distraction: The players who won the final are celebrating. (subject = players)
3. Inverted order with there: There are three reasons. / There is one problem. (true subject follows)
4. Titles and amounts: "Fables and Storms" is her favourite book. / Five dollars is enough for the fare. (often singular as a unit)
5. Collective nouns: stay consistent — The committee has reached its decision (unit) vs The committee have taken their seats (members; more common in some varieties). Match the verb to the intended meaning and keep pronouns consistent.

ICAS strategy: Cross out prepositional phrases temporarily and re-read subject + verb only: The basket … is heavy.

Active and Passive Voice

Active voice: the subject does the action.
The ranger closed the gate.

Passive voice: the subject receives the action; form = be + past participle (optional by-phrase).
The gate was closed by the ranger. / The gate was closed.

Original pairs

• Active: Researchers recorded the bird calls at dawn.
• Passive: The bird calls were recorded at dawn.

ICAS may ask which sentence is passive, which keeps the same meaning in a voice change, or which version is clearer. Meaning can shift slightly if the agent disappears: Mistakes were made hides who made them.

Voice is not tense. was written is past passive; is being written is present continuous passive. Identify tense and voice separately when options mix both.

Pronoun Reference: Clear Antecedents

A pronoun needs a clear antecedent (the noun phrase it stands for). Agreement covers number, person and, where relevant, gender/neutral sense.

Simple reference (early-paper style)

• Leila lost her ticket. → her = Leila
• The dogs chased their shadows. → their = the dogs

Complex reference (upper-paper style)

Original mini-passage:

After the principal met the coaches, she asked them to rewrite the schedule. This delayed the tournament booklet by two days.

Check each pronoun:

• she — must clearly mean the principal (only one singular female noun available here)
• them — the coaches (plural)
• This — risky: does This mean the meeting, the request, or the rewrite? ICAS often flags vague this/that/it that points to a whole event without a clear noun

Safer rewrite: That request delayed the tournament booklet by two days. or Rewriting the schedule delayed the tournament booklet by two days.

Ambiguous pronouns (high-value trap)

Original problem sentence:

When Nadia finally spoke to Priya, she was already late.

Who was late — Nadia or Priya? Both are possible. Strong options either rename the person (Priya was already late) or restructure (Nadia was already late when she finally spoke to Priya).

Another trap:

The committee told the volunteers that they would meet on Friday.

Does they mean the committee or the volunteers? Fix by repeating the noun: … that the volunteers would meet on Friday.

Pronoun–antecedent agreement patterns

Putting It Together: Original Mini-Passage Analysis

Last March the science club built a weather station behind the gym. By April the sensors had already collected enough data for a display, and the results were presented at assembly by two Year 8 students. They explained how rainfall totals rose after the coastal storm. Everyone was listening so carefully that the hall stayed silent until the final slide.

ICAS Multiple-Choice Angles

Expect stems such as:

• "Which verb correctly completes the sentence?"
• "Which sentence keeps a consistent tense?"
• "Which option shows correct subject–verb agreement?"
• "Which sentence is written in the passive voice?"
• "What does the word it refer to in the passage?"
• "Which revision best removes the unclear pronoun?"

Attack plan

1. Find time markers (yesterday, by then, since Monday, now).
2. Locate the grammatical subject — not the nearest noun.
3. Check whether the question wants tense, agreement, voice or reference; do not fix the wrong problem.
4. For pronouns, draw a quick arrow to one antecedent only; if you can draw two, the pronoun is ambiguous.
5. Prefer options that keep meaning while fixing grammar, not options that change the facts of the passage.

Quick Error Clinic

Master these four areas — tense staging, agreement, voice and reference — and you can handle most sentence-level Syntax questions that sit on top of word-class and clause knowledge from the earlier sections of this chapter.
