Verb tense: stay consistent and know irregular forms
⏱️ "She walked in and starts the IV" jumps from past to present mid-sentence. Readers notice, and so does the TEAS.
💡 Key idea
Hold one time frame unless the meaning changes, and use the participle form after has, have or had.
🧠 The idea
TENSE tells when an action happens. Simple tenses: past (charted), present (charts), future (will chart). Perfect tenses link two times: present perfect (has charted) for an action that began in the past and continues or matters now; past perfect (had charted) for an action finished before another past action. Keep TENSE CONSISTENCY: do not switch tenses within a sentence or paragraph unless the time really changes. Many common verbs are IRREGULAR VERBS that do not add -ed: begin, began, begun; write, wrote, written; take, took, taken; go, went, gone; see, saw, seen; lie (recline), lay, lain; lay (put down), laid, laid. The past participle (begun, written, taken) follows a helping verb such as has, have or had. The simple past (began, wrote, took) stands alone. Mixing these up, as in "I seen" or "she had wrote," is a common error.
✏️ Worked example
"By the time the doctor arrived, the nurse (already gave / had already given) the medication." Step 1: two past actions; the giving happened first. Step 2: the earlier past action takes past perfect: had + past participle. Step 3: the participle of give is given. Answer: "the nurse had already given the medication."
📌 Takeaways
- Match tenses in a sentence unless the time really changes.
- Had + participle = the earlier of two past actions.
- Simple past stands alone (wrote); participle needs a helper (has written).

Question 1 of 3
Which sentence keeps verb tense consistent?
- Kim opened the textbook and finds the chapter on cells.
- Kim opens the textbook and found the chapter on cells.
- Kim will open the textbook and found the chapter on cells.
- Kim opened the textbook and found the chapter on cells.
Show the answer and rationale
Answer: D
Opened and found are both simple past, so the time frame stays consistent. The other sentences switch between present and past or between future and past for two actions that happen at the same time.
Question 2 of 3
Which verb correctly completes the sentence? "The students have ___ three practice tests this month."
- taked
- take
- took
- taken
Show the answer and rationale
Answer: D
After the helping verb have, use the past participle, which for take is taken. Took is the simple past and cannot follow have, taked is not a word, and take is the base form.
Question 3 of 3
Which sentence uses the past perfect correctly?
- Rosa had finish her shift before the storm began.
- Rosa had finished her shift before the storm has begun.
- Rosa has finished her shift before the storm had began.
- Rosa had finished her shift before the storm began.
Show the answer and rationale
Answer: D
Finishing came first, so had finished (past perfect) is correct, and began is the right simple past. Had began uses the wrong form after had, has begun shifts into present perfect for a past event, and had finish needs the participle finished.
