Verb tense

Verb tense shows when something happens. Pick the tense that matches the time, then keep it steady: do not switch between past and present unless the time really changes. Use the perfect tenses to show order or connection: had left means it happened before another past event, and has lived means it started in the past and still matters now. When writing about a novel or poem, use the present tense.

Worked examples

Example 1: which happened first?

Problem By the time we (arrived / had arrived), the movie (started / had started).

  1. Put the events in order: the movie started first, then we arrived.
  2. The earlier past event takes the past perfect: had started. The later one is simple past: arrived.

Answer By the time we arrived, the movie had started.

Example 2: fix a tense shift in a paragraph

Problem Last summer our team traveled to Ohio. We play four games and win three. On the last day, we visited a science museum.

  1. The paragraph is about last summer, so the story is in the past.
  2. Play and win shift to the present for no reason. Change them to played and won.

Answer Last summer our team traveled to Ohio. We played four games and won three. On the last day, we visited a science museum.

Practice

Five verb tense questions

  1. Yesterday, I walked to the store and ___ some milk.

    1. buy
    2. have bought
    3. will buy
    4. bought
    Show answer

    Answer: bought

    Yesterday and walked set a finished past time, so the second verb is simple past too. Buy is present, will buy is future, and have bought does not fit a specific past time like yesterday.

  2. By the time we arrived, the movie ___.

    1. starts
    2. will start
    3. had started
    4. has started
    Show answer

    Answer: had started

    The movie started before another past event (we arrived), so use the past perfect had started. The other choices put the start in the present or the future.

  3. She ___ in this town since 2019.

    1. lives
    2. has lived
    3. lived
    4. will live
    Show answer

    Answer: has lived

    Since 2019 means it began in the past and is still true, which calls for the present perfect has lived. The simple present, simple past and future do not fit with since.

  4. In a literature essay: In the novel, the main character ___ the letter and decides to leave home.

    1. read
    2. had read
    3. reads
    4. will read
    Show answer

    Answer: reads

    Essays about literature use the present tense for events in the story, and decides is already present. Reads matches it. The others shift the tense.

  5. The bell had already ___ when I got to class.

    1. rang
    2. ringed
    3. rung
    4. ring
    Show answer

    Answer: rung

    After had, use the past participle. For ring, that is rung. Rang is the simple past, ringed is not the standard form for a bell, and ring is the base form.

Frequently asked questions

Should I write my essay in past or present tense?

For essays about a novel, poem or film, use the present tense for what happens in the work. For a personal story, past tense is most natural. For a research paper, follow your style guide: APA, for example, recommends past tense or present perfect when describing other researchers' work.

What is the difference between I ate and I have eaten?

I ate points to a finished time: I ate at noon. I have eaten connects the past to now without a specific time: I have eaten, so I am not hungry. If you name a finished time like yesterday, use the simple past.

Does the SAT test verb tense?

Yes. College Board lists Verb Tense and Aspect as part of the Form, Structure, and Sense skill. Questions give a short passage and ask which verb form fits the timeline set by the other verbs and dates. See SAT Form, Structure, and Sense.
