Verb Forms and Tenses
Verb tense questions test whether you can keep events on a clear timeline. Past, present, future — and the *perfect* tenses that pin one event before another.
| Tense | Form | Use |
|---|---|---|
| Simple past | *walked* | Completed event in the past |
| Past continuous | *was walking* | Action in progress at a past moment |
| Past perfect | *had walked* | Earlier of two past events |
| Simple present | *walks* | Habitual or general truth |
| Present continuous | *is walking* | Action in progress now |
| Present perfect | *has walked* | Started in past, continues / relevant now |
| Simple future | *will walk* | Will happen at some future point |
| Future perfect | *will have walked* | Will be done before some future point |
Read the sentence's timeline. If there are two past events, the earlier one takes past perfect (*had + past participle*). If something started in the past and continues now, use present perfect.

Common pitfalls
"She walked in and buys milk" — switch is unjustified. Stay in one tense unless the timeline genuinely shifts (event happened before another, etc.).
Past perfect (had + past participle) is only for the earlier of two past events. Don't use it for a single past event — that's simple past. "I had eaten breakfast" is wrong on its own; you need a second past event to anchor had.
"I have visited Paris last summer" is wrong — last summer is a specific past time, demanding simple past. Right: "I visited Paris last summer." Or: "I have visited Paris" (without the time).
Lay (transitive: lay-laid-laid) vs lie (intransitive: lie-lay-lain). Bring/brought vs take/took. Swim/swam/swum. The SAT routinely tests these. Memorize the principal parts.
Key takeaways
Stay consistent in tense unless the timeline genuinely shifts within the sentence.
Past perfect (had + past participle) = the earlier of two past events.
Present perfect (has/have + past participle) = action that started in the past and continues / remains relevant.
Don't pair present perfect with a specific past time (yesterday, in 2010) — use simple past instead.
Memorize irregular verbs: lay/laid/laid, lie/lay/lain, swim/swam/swum, go/went/gone.
