Overview
Verb Tense, Voice, and Mood questions test whether students can select the correct verb form to maintain tense consistency, use the appropriate verb tense to sequence events, apply the correct voice (active or passive), and recognize when the subjunctive mood is required. These questions fall under Form, Structure, and Sense. The most commonly tested issues are tense consistency, past perfect vs. simple past, and subjunctive mood in contrary-to-fact conditions. Students must scan the passage for time markers, signal words, and context to determine the required form.
Key Points
1. Tense Consistency
The tense of a verb must match the established timeline of the passage. Only shift tense when the content signals a genuine change in time.
Wrong: “The researcher collected the samples and then examines them under a microscope.” Correct: “The researcher collected the samples and then examined them under a microscope.”
Exception — general truths: Even in a past-tense passage, use present tense for facts that are still true today. “Newton demonstrated that gravity pulls objects toward the Earth.” (“pulls” = present, because gravity still operates now)
| Signal Word/Phrase | Expected Tense |
|---|---|
| ”yesterday,” “last year,” “in 1990” | Simple past |
| ”currently,” “now,” “today,” “always” | Simple present |
| ”before [past event]“ | Past perfect (had + past participle) |
| “by the time,” “after” (with past events) | Past perfect |
| ”will,” “next year,” “in the future” | Future or future perfect |
2. Simple Past vs. Past Perfect
Use simple past for a past action. Use past perfect (had + past participle) for a past action that occurred BEFORE another past action.
Sequence rule: Earlier event → past perfect; Later event → simple past.
“By the time the results arrived, the team had already submitted its report.” (Submitting happened first → past perfect; arriving happened second → simple past)
“The archaeologist found an artifact that had been buried for centuries.” (Being buried happened first → past perfect; finding happened second → simple past)
3. Active vs. Passive Voice
Active voice: Subject performs the action. (Subject → Verb → Object) Passive voice: Subject receives the action. (Subject → “to be” + past participle)
| Voice | Example |
|---|---|
| Active | ”The team analyzed the data.” |
| Passive | ”The data was analyzed by the team.” |
The SAT prefers active voice for clarity and concision. Choose active when:
- The actor (agent) is known
- The active version is more direct and concise
Passive voice is acceptable when:
- The actor is unknown: “The artifact was discovered in 1975.”
- The actor is unimportant: “The samples were processed overnight.”
4. Subjunctive Mood
The subjunctive mood expresses hypothetical, contrary-to-fact, wished-for, or recommended situations.
Two main contexts:
A. Contrary-to-fact conditions (if-clauses): Use “were” (not “was”) for ALL subjects in hypothetical conditions.
| Wrong | Correct |
|---|---|
| ”If she was the director…" | "If she were the director…" |
| "If I was taller…" | "If I were taller…" |
| "He acts as if he was the boss." | "He acts as if he were the boss.” |
B. After verbs of recommendation (recommend, suggest, advise, require, insist, demand, propose) + “that”: Use the base form of the verb (infinitive without “to”) — no -s ending, no -ed, no auxiliary.
| Wrong | Correct |
|---|---|
| ”She recommended that he studies." | "She recommended that he study." |
| "The rules require that she attends." | "The rules require that she attend." |
| "I suggest that he is more careful." | "I suggest that he be more careful.” |
5. Gerunds vs. Infinitives
A gerund is a verb form ending in -ing used as a noun (studying, running). An infinitive is “to + base verb” (to study, to run).
Certain verbs demand one form or the other:
| Verb type | Examples | Required form |
|---|---|---|
| Followed by gerund only | enjoy, avoid, consider, finish, practice, admit, deny | ”She enjoys reading.” |
| Followed by infinitive only | want, hope, plan, decide, agree, refuse, expect | ”She decided to read.” |
| Followed by either (similar meaning) | like, love, hate, begin, start, continue, prefer | ”She likes to read.” / “She likes reading.” |
Pitfalls and Common Mistakes
Pitfall 1: Tense Shift in the Middle of a Narrative
Description: A passage written consistently in the past tense contains a verb that unexpectedly shifts to present tense without a time-signal justification.
Wrong: “The explorer traveled for months, navigates difficult terrain, and finally discovers the ancient city.” Correct: “The explorer traveled for months, navigated difficult terrain, and finally discovered the ancient city.” Fix: Identify the dominant tense of the passage. Align all verbs to that tense unless a general truth or explicit time signal demands a different tense.
Pitfall 2: “If…Would Have” Past Subjunctive Error
Description: Students use “if…would have” thinking it correctly expresses a past hypothetical. This construction is always wrong on the SAT.
Wrong: “If she would have trained harder, she would have won.” Correct: “If she had trained harder, she would have won.” Fix: In the “if” clause of a past hypothetical, always use “had + past participle.” The “would have” belongs in the result clause only.
Pitfall 3: Forgetting “Were” in Contrary-to-Fact Conditions
Description: Students use “was” instead of “were” in subjunctive if-clauses because “were” sounds odd with singular subjects.
Wrong: “If the experiment was successful, we would publish immediately.” Correct: “If the experiment were successful, we would publish immediately.” (hypothetical, not yet done) Fix: The signal is counterfactual or hypothetical meaning. Any condition that is contrary to fact, doubtful, or wished-for takes “were” for all persons and numbers.
Pitfall 4: Missing Past Perfect for Sequence of Events
Description: Two past events are described, but both use simple past — failing to indicate which happened first.
Wrong: “She submitted the report before the editor reviewed the draft.” Correct: “She had submitted the report before the editor reviewed the draft.” (submission came first) Fix: When describing two past events, the earlier one takes past perfect. Signal words: “before,” “after,” “by the time,” “already,” “when.”
Pitfall 5: Passive Voice When Active Is Available and Clearer
Description: Passive voice is used when an active construction is available, making the sentence wordy or unclear.
Wrong: “The discovery was made by the research team in 2022, and the data was published by them.” Correct: “The research team made the discovery in 2022 and published the data.” Fix: If the actor is known and relevant, rewrite as active voice. Active voice is shorter and usually preferred on the SAT.

Quick Reference Card
| Concept | Rule | Example |
|---|---|---|
| Tense consistency | Match established passage tense | Past passage → past verbs throughout |
| General truth | Use present even in past-tense passage | ”Newton showed that gravity pulls…” |
| Past perfect | Earlier of two past events | ”She had left before he arrived.” |
| Subjunctive (if-clause) | Use “were” not “was" | "If I were you…” |
| Subjunctive (recommend that) | Use base verb, no -s | ”I recommend that she attend.” |
| If…would have | ALWAYS WRONG | Correct: “If she had studied, she would have passed.” |
| Active vs. passive | Prefer active when actor is known | ”The team analyzed the data.” |
