Use correct verb tense and verb form; keep tense consistent within a sentence.
Pick the verb tense that matches the time frame and sequence.
核心知识
Pick the verb tense that fits the sentence's time frame, and don't shift tenses without a reason. The SAT tests whether you can match verb forms to context clues — time markers, other verbs, and the logic of the passage.
深入理解
Verb tense errors come in two flavors:
Wrong tense for the context. The passage describes events in the past, but one verb suddenly appears in the present. Or a sentence uses the past perfect ("had written") when simple past ("wrote") is all that's needed.
Inconsistent tense within a sentence. "She opened the door and sees a package" — the shift from past to present has no justification.
To pick the right tense, look for context clues:
- Time markers: "in 1995," "recently," "by the time," "since then"
- Other verbs in the sentence or passage — they set the tense baseline
- Logical sequence: did one event happen before another? That's where past perfect ("had + past participle") earns its place
The key SAT tenses:
- Simple past: completed action — "discovered"
- Present: habitual or ongoing truth — "suggests"
- Past perfect: action completed before another past action — "had published (before she won)"
- Present perfect: past action with present relevance — "has influenced (and still does)"
Rule of thumb: don't change tenses unless the time frame changes.
分步讲解
- Read the full sentence and note any time markers (dates, words like "before," "since," "recently").
- Identify the tense of other verbs in the sentence — this is your baseline.
- Ask: does the blank describe something happening at the same time, before, or after the other actions?
- Match the verb form to that time relationship.
- Eliminate choices that create an unjustified tense shift.
常见误解
- Thinking the past perfect ("had done") should be used whenever something happened in the past. It's only needed when you're marking one past event as happening before another past event.
- Believing tense should never change within a passage. Tense shifts are fine when the time frame genuinely shifts — the error is shifting without reason.
- Confusing verb form errors with tense errors. "The data shows" vs. "the data show" is an agreement issue, not a tense issue.
