4.6 Inappropriate Shifts in Verb Voice and Mood
Key Takeaways
- The official skill is recognizing and correcting inappropriate shifts in verb voice and mood within and between sentences.
- Passive voice is not an error; it becomes a defect only when it shifts inconsistently or hides a needed actor.
- Mood shifts occur most often when a sentence begins as a command and switches to a statement or vice versa.
- The subjunctive uses were for all subjects in contrary-to-fact conditions and the base verb in that-clauses of demand or recommendation.
- Parallel structure and voice consistency interact, so a compound predicate mixing active and passive is usually wrong on both counts.
Two Properties Beyond Tense
Inappropriate shifts in verb voice and mood: The student will recognize and correct inappropriate shifts in verb voice and mood within and between sentences.
Every English verb carries three properties the test examines: tense (when), voice (whether the subject acts or is acted upon), and mood (whether the verb states, commands, or hypothesizes). Tense has its own skill statement; voice and mood share this one.
Voice
Active and Passive
Active: the subject performs the action.
The inspectors reviewed the maintenance logs.
Passive: the subject receives the action. Built from a form of be plus a past participle, optionally with a by phrase.
The maintenance logs were reviewed by the inspectors.
Passive Voice Is Not an Error
This point is worth stating plainly, because many students arrive believing passive constructions are always wrong. They are not, and the test does not treat them as such. Passive voice is the better choice when:
- The actor is unknown. The samples were mislabeled at some point during transport.
- The actor is irrelevant. The specimens were stored at four degrees Celsius.
- The recipient is the topic. In a paragraph about the logs, the logs were reviewed keeps the subject in focus.
- Scientific convention applies. Methods sections routinely use passive constructions.
What the test penalizes is inconsistency and evasion.
The Mid-Sentence Shift
The classic tested error changes voice inside a single sentence, usually across a compound predicate:
✗ The committee reviewed the proposal, and several revisions were requested.
The first clause is active with the committee acting; the second goes passive and drops the actor. Repair:
✓ The committee reviewed the proposal and requested several revisions.
Notice this repair also fixes a parallelism problem — the compound predicate now uses two matching active verbs. Voice consistency and parallel structure frequently travel together, and a single revision resolves both.
Evasive Passive
When a passage identifies who acted, hiding them behind a passive construction is a defect:
✗ Mistakes were made in the calculation of the load tolerances.
If the passage establishes that the engineering firm performed the calculation, the active version is stronger and more informative: The engineering firm miscalculated the load tolerances.
Mood
English has three moods.
| Mood | Function | Example |
|---|---|---|
| Indicative | States facts, asks questions | The valve closes automatically. |
| Imperative | Gives commands or instructions | Close the valve before servicing. |
| Subjunctive | Expresses wishes, hypotheticals, demands | If the valve were open, pressure would drop. |
Imperative-Indicative Shifts
Most mood errors on the test involve instructional writing that cannot decide whether it is issuing commands or describing them:
✗ First, disconnect the power supply. Then the housing should be removed.
The first sentence is imperative; the second switches to indicative passive. Repair by holding one mood:
✓ First, disconnect the power supply. Then remove the housing.
The same shift occurs within a sentence:
✗ Record the ambient temperature, and then you should calibrate the sensor. ✓ Record the ambient temperature, and then calibrate the sensor.
A related error introduces you into an otherwise imperative sequence, which is simultaneously a mood shift and a pronoun person shift.
The Subjunctive
The subjunctive is limited in modern English but reliably tested in two constructions.
1. Contrary-to-fact conditions. Use were for every subject, including singular ones:
✓ If the reservoir were full, the district would not ration water. (it is not full) ✗ If the reservoir was full...
But when the if clause describes something that may actually be true, the indicative is correct:
✓ If the reservoir was full in June, the records will show it. (it may have been)
The distinction is factual, not grammatical: contrary to fact takes were; genuinely uncertain takes was.
The same rule covers wish: I wish the schedule were more flexible.
2. That-clauses after demand, request, or recommendation. Use the base form of the verb, with no -s and no to:
✓ The board recommended that the district hire an independent auditor. (not hires) ✓ Regulations require that each valve be inspected annually. (not is)
Triggering verbs and nouns: demand, insist, require, recommend, request, suggest, propose, ask, move, plus it is essential/necessary/imperative that.
The base form looks wrong to many ears because it disagrees with the subject in the ordinary way — that the district hire rather than hires. That apparent disagreement is exactly what makes it correct here.
Working the Question Type
- Identify the voice and mood of the surrounding sentences.
- Ask whether the underlined portion matches.
- If it does not, ask whether the content justifies the change.
- Check for the two subjunctive triggers, since those override consistency.
As with tense, the error is only visible against context. An underlined should be removed is perfectly grammatical on its own; it is wrong only because the sentence before it issued a command.
