This is one of the most powerful moves in the verb system. English has many tenses, present, past, future, and their combinations, and most courses ask you to memorise a confusing feeling for each. We'll do something far better: read the time and the voice of a verb straight from the chain of small helping words in front of it. The Boot you already know does most of the work, and the scary tense system turns into something you simply read off the page.
1. The big idea: read the helping verbs, don't "feel" the tense
Most learners try to feel whether a sentence is past, present, or future. That's slow and unreliable. This method does something smarter:
The small helping words in front of the main verb tell you everything, the time and the voice. You just read the chain.
What's a "chain"? It's the sequence of little helping verbs that sit before the main verb. For example, in has been repaired, the chain is has + been in front of repaired. Each link in the chain adds a specific piece of meaning. Once you learn what each link means, you can read any verb's tense and voice like reading a code.
And here's the wonderful part: the most important links in these chains are Boot words, be, been, being, was, were, is, are, which you already know cold from The Boot: The Most Powerful Tool in This Whole Series. So you've already done most of the learning!
Quick recap: Don't "feel" the tense, READ the chain of helping verbs before the main verb. Each helping word adds meaning. Most of these helping words are Boot words you already know.
2. Three things the chain tells you: tense, aspect, voice
The chain of helping verbs encodes three pieces of information. Let me explain each gently.
Tense = WHEN (the time). Is the action in the present, the past, or the future?
- writes (present), wrote (past), will write (future)
Aspect = HOW the action is viewed. Is it simple, ongoing (continuous), or completed-and-connected (perfect)?
- writes (simple, just a fact), is writing (continuous, happening right now), has written (perfect: done, and connected to now)
Voice = WHO is in the subject position. Does the subject do the action (active) or receive it (passive)?
- She repaired the car (active, she does it), The car was repaired (passive, it receives it)
So when you read a verb chain, you're reading three things at once: when (tense), how viewed (aspect), and who's in the subject seat (voice). Don't worry; you don't have to name all three every time. Mostly, you just read the chain and the meaning appears.
Worth repeating: The verb chain tells you three things: TENSE (when, past/present/future), ASPECT (how viewed, simple/continuous/perfect), and VOICE (who's in the subject seat, active/passive).
3. The building blocks of the chain
Before the tables, let's learn the small set of building blocks. Every verb chain is made from these:
-
the main verb's forms:
- base form: write, repair
- -s form: writes, repairs (present, for he/she/it)
- past form: wrote, repaired
- -ing form (present participle): writing, repairing
- past participle (P.P.): written, repaired (the "done-to" form)
-
helping words:
- will (for the future)
-
have / has / had (for "perfect", completed and connected)
-
the Boot words: am, is, are, was, were, be, been, being
The two participle forms matter most:
- the -ing form signals continuous (ongoing) action.
- the past participle (P.P.) signals either perfect (with have) or passive (with be).
A quick note on the past participle: for regular verbs it's just the -ed form (repaired, worked). For irregular verbs you memorize it (write → written, break → broken, see → seen). There's a short irregular-verb list in section 9.
Lock this in: Chain building blocks: the main verb's forms (base, -s, past, -ing, past participle), plus helping words will, have/has/had, and the Boot words. The -ing form = continuous; the past participle = perfect (with have) or passive (with be).
4. The ACTIVE tenses (the subject does the action)
Here's the table of active tenses, the subject does the action. Read each formula as a chain. Notice how the building blocks combine:
| Tense | Formula (the chain) | Example |
|---|---|---|
| present simple | base / -s | I read. / She reads. |
| past simple | past form | She wrote it. |
| future simple | will + base | I will read. |
| present continuous | am/is/are + -ing | I am reading. |
| past continuous | was/were + -ing | She was reading. |
| future continuous | will + be + -ing | They will be reading. |
| present perfect | have/has + P.P. | I have read. |
| past perfect | had + P.P. | She had read. |
| future perfect | will + have + P.P. | They will have read. |
| present perfect continuous | have/has + been + -ing | I have been reading. |
Look at the patterns:
- continuous (ongoing) = a Boot word (am/is/are/was/were/be) + the -ing form.
- perfect (completed/connected) = have/has/had + the past participle.
- future = will + (whatever follows).
You don't need to memorize the names perfectly. What matters is reading the chain: see have + read → "completed, connected to now" (present perfect). See was + reading → "ongoing in the past" (past continuous). The chain is the evidence.
A quick reminder: Active tenses: continuous = Boot + -ing (is reading); perfect = have/has/had + past participle (has read); future = will + ... Read the chain to get the meaning; you don't have to name it.
5. The "voice" idea: active vs. passive
Before the passive table, let's make sure "voice" is crystal clear, because it's the part most learners find new.
Active voice: the subject does the action.
- The technician repaired the machine. → the technician does the repairing. The technician is the doer.
Passive voice: the subject receives the action; it's "done to" the subject. The doer disappears or moves to a by phrase.
- The machine was repaired (by the technician). → the machine didn't do anything; it got repaired. The machine is in the subject seat, but it's the receiver.
Why does English use the passive? When the doer is unknown, unimportant, or obvious, or when we just want to focus on the thing affected. This is extremely common in science and formal writing: The samples were analyzed (we don't care who analyzed them; we care about the samples).
The absolute passive rule (this is the Boot again!)
Here's the rule, and it's the Boot from The Boot: The Most Powerful Tool in This Whole Series doing real work:
Every passive = a Boot word + a past participle. No exceptions. If you see be/is/was/were/been/being + a past participle (-ed/-en word), it's passive.
- was repaired → was (Boot) + repaired (P.P.) = passive ✓
- is reviewed → is + reviewed = passive ✓
- will be cleaned → be (Boot) + cleaned = passive ✓
- has been sold → been (Boot) + sold = passive ✓
And the reverse: if there's no Boot + past participle, it's NOT passive. This single rule lets you spot any passive instantly.
Say it again: Active = subject DOES the action. Passive = subject RECEIVES it (done to it). The absolute rule: every passive = a Boot word + a past participle (was repaired, is reviewed, has been sold). No Boot + P.P. = not passive.
6. The PASSIVE tenses (the subject receives the action)
Now the passive table. Notice every single one contains a Boot word + past participle, exactly as the rule says:
| Tense | Formula (the chain) | Example |
|---|---|---|
| present simple passive | am/is/are + P.P. | Books are sold here. |
| past simple passive | was/were + P.P. | The window was broken. |
| future simple passive | will + be + P.P. | It will be fixed. |
| present continuous passive | am/is/are + being + P.P. | It is being repaired. |
| past continuous passive | was/were + being + P.P. | It was being fixed. |
| present perfect passive | have/has + been + P.P. | It has been sold. |
| past perfect passive | had + been + P.P. | It had been lost. |
See how being appears in the continuous passives (is being repaired) and been appears in the perfect passives (has been sold)? Those are the rarer Boot words from The Boot: The Most Powerful Tool in This Whole Series finally showing their purpose. Every passive, simple or complex, is built on Boot + P.P.
Hold onto this: Every passive tense = Boot + past participle. Continuous passive uses being (is being repaired); perfect passive uses been (has been sold). The Boot word changes with the tense, but it's always there.
7. The crucial contrasts (don't mix these up!)
Two pairs cause the most confusion. Let's nail them with the Boot.
Active perfect vs. passive perfect
- The engineer has repaired the device. → has + repaired (no Boot between them) = active perfect (the engineer did it).
- The device has been repaired. → has + been (Boot!) + repaired = passive perfect (it received the action).
The difference is the little word been (a Boot word). has repaired = active; has been repaired = passive. One word changes everything.
Active continuous vs. passive continuous
- The students are presenting the results. → are + presenting (-ing) = active continuous (they're doing it).
- The results are being presented. → are + being (Boot) + presented (P.P.) = passive continuous (they're receiving it).
Again, the Boot word being + the past participle signals the passive.
So whenever you're unsure if something is active or passive, check for Boot + past participle. If it's there, it's passive. That one test resolves these tricky pairs every time.
One more time: has repaired = active; has BEEN repaired = passive (the word been makes it passive). are presenting = active; are BEING presented = passive. Check for Boot + past participle to decide.
8. The informal "get" passive
A quick bonus. In casual, spoken English, people often use get instead of be for the passive:
- formal: The window was broken. → casual: The window got broken.
- formal: She was promoted. → casual: She got promoted.
- He got fired. / The file got corrupted.
The get-passive follows the same idea (a helping verb + past participle), but uses get/got/getting instead of a Boot word. It often suggests something happened unexpectedly, accidentally, or unfortunately (The cable got cut. He got arrested.).
Reading rule: when you see get/got/getting + a past participle, read it as a passive, not as "get" (the main verb) + an adjective. got damaged = passive of damage, meaning "was damaged."
Check yourself: Casual English uses get for the passive: got broken, got promoted, got fired. It often implies something unexpected or unfortunate. Read got + past participle as a passive.
9. A short irregular-verb reference
To read perfect and passive forms, you need the past participle of common irregular verbs. Here's a starter set to memorize over time (base / past / past participle):
| Base | Past | Past participle |
|---|---|---|
| be | was/were | been |
| have | had | had |
| do | did | done |
| go | went | gone |
| see | saw | seen |
| take | took | taken |
| give | gave | given |
| make | made | made |
| write | wrote | written |
| break | broke | broken |
| begin | began | begun |
| know | knew | known |
| run | ran | run |
(Regular verbs are easy, the past and past participle are both just -ed: work → worked → worked.)
10. Back to the core idea
This post is, at heart, the Boot (The Boot: The Most Powerful Tool in This Whole Series) in full bloom. The Boot told you that be forms are special; here you see exactly why; they build every continuous and every passive. When you read a verb chain, you're scanning for Boot words and participles, and their arrangement gives you the tense and voice.
It also connects to the structural mindset (The Structural Mindset: Training Your Eyes to See the Shape): finding the full verb chain (not just one word) is part of finding the main verb. A learner who grabs only repaired might miss that the real verb is has been repaired, a whole chain. Reading the chain as a unit keeps your parsing accurate.
And the absolute passive rule (Boot + P.P.) will be essential for the advanced posts, where you'll separate true passive main verbs (was repaired, Boot present) from squeezed-down describers (repaired, no Boot, an RT2 reduced relative from The M5 Zone: Full Describing Clauses (a Major Milestone)). The Boot keeps drawing that line.
11. Give these a try
Try each yourself first, then check the answers.
Exercise A: Name the tense (and active or passive)
- She is writing a letter now.
- They had arrived before noon.
- The car was repaired last week.
- I will have finished by 5 p.m.
- He has been studying for three hours.
- The report is being written.
Exercise B: Active or passive? (use the Boot + P.P. test)
- The engineer has tested the device.
- The device has been tested.
- The students are presenting the results.
- The results are being presented.
Exercise C, Build the verb chain
- She / present perfect active / write an email
- The book / past simple passive / publish
- They / future continuous / travel
- He / present perfect continuous / work
Exercise D, The "get" passive
Rewrite each formal passive as a casual get-passive.
- The window was broken.
- She was promoted.
Answers (try first, then check!)
Exercise A, Name the tense:
- present continuous (active), is + -ing
- past perfect (active), had + P.P.
- past simple passive, was + P.P.
- future perfect (active), will have + P.P.
- present perfect continuous (active), has been + -ing
- present continuous passive, is being + P.P.
Exercise B: Active or passive?
- has tested → active (no Boot between has and tested)
- has been tested → passive (been + P.P.)
- are presenting → active (are + -ing)
- are being presented → passive (being + P.P.)
Exercise C, Build the verb chain:
- She has written an email. (have/has + P.P.)
- The book was published. (was + P.P.)
- They will be traveling. (will + be + -ing)
- He has been working. (have/has + been + -ing)
Exercise D, The "get" passive:
- The window got broken.
- She got promoted.
How did you do? Exercise B is the crucial one, if you can use the Boot + P.P. test to separate active from passive, you've mastered the heart of the whole tense system.
12. What to hold on to
-
Don't "feel" the tense, read the chain of helping verbs before the main verb. The chain encodes everything.
-
The chain shows three things: tense (when), aspect (simple/continuous/perfect), voice (active/passive).
-
In the chain: continuous = Boot + -ing (is reading); perfect = have/has/had + past participle (has read); future = will + ...
-
Active = subject does the action. Passive = subject receives it (done to it).
-
The absolute passive rule: every passive = a Boot word + a past participle (was repaired, is reviewed, has been sold). No Boot + P.P. = not passive.
-
Crucial contrasts: has repaired (active) vs. has been repaired (passive, note been); are presenting (active) vs. are being presented (passive, note being).
-
Casual English uses the get-passive (got broken, got promoted), often implying something unexpected/unfortunate.
-
This is the Boot in full bloom, Boot words build every continuous and every passive.
13. Closing thought
You've now turned the scary tense system into something you can simply read off the page, by scanning the chain of helping verbs and applying the Boot. That's a huge upgrade in your reading power, and it's the same Boot you learned back in The Boot: The Most Powerful Tool in This Whole Series, finally showing its full strength.
In The -ing Puzzle: One Procedure to Sort Out Every "-ing" Word, we'll bring together everything about the -ing form into one clear system, the "-ing puzzle." That little ending can be a verb, a thing (gerund), a describer, or a squeezed-down clause, and you'll learn one reliable procedure (using the Boot, of course) to sort out which is which, every time.
