Basics. Past Simple and Past Continuous/Progressive Tenses.
Past Simple (I did)
Explanation and Examples
The Past Simple tense is used to describe actions or events that happened in the past and are now completed. These actions or events can be specific or general, with a definite beginning and end.
Examples:
- I worked at a bookstore last year.
- She visited Paris two months ago.
Formation
To form the Past Simple tense, we use the past form of the main verb. For regular verbs, we add -ed to the base form. For example:
| Base Form | Past Simple |
|---|---|
| work | worked |
| study | studied |
However, some verbs are irregular and have a different past form. For example:
| Base Form | Past Simple |
|---|---|
| go | went |
| be | was / were |
Past Simple is different from Present Simple, which describes habits or facts in the present. It also differs from Past Continuous, which describes ongoing actions in the past.
Negative Sentences
To form negative sentences in Past Simple, we use did not (or didn't) followed by the base form of the verb.
| Past Simple | Negative Past Simple |
|---|---|
| worked | didn't work |
| visited | didn't visit |
Questions
To form questions in Past Simple, we use did followed by the subject and the base form of the verb.
| Past Simple | Question Past Simple |
|---|---|
| worked | Did you work? |
| visited | Did she visit? |
Past Continuous (I was doing)
Explanation and Examples
The Past Continuous tense is used to describe actions or events that were ongoing or in progress at a specific time in the past. This tense emphasizes the duration or continuity of the action.
Examples:
- I was working at a bookstore when you called.
- She was visiting Paris when it started raining.
Formation
To form the Past Continuous tense, we use the past form of the verb to be (was/were) followed by the -ing form of the main verb.
Examples:
| Subject | Past Continuous |
|---|---|
| I | was working |
| They | were studying |
Past Continuous is different from Past Simple, which describes completed actions in the past. It also differs from Present Continuous, which describes ongoing actions in the present.
Negative Sentences
To form negative sentences in Past Continuous, we add not after the past form of the verb to be (was/were).
| Past Continuous | Negative Past Continuous |
|---|---|
| was working | wasn't working |
| were studying | weren't studying |
Questions
To form questions in Past Continuous, we invert the subject and the past form of the verb to be (was/were), followed by the -ing form of the main verb.
| Past Continuous | Question Past Continuous |
|---|---|
| was working | Was I working? |
| were studying | Were they studying? |
Verb
A verb is a word that expresses an action, a state, or an occurrence — the engine of every English sentence. Most verbs have five forms: base (go), -s form (goes), past tense (went), past participle (gone), and -ing form (going). The verb be is the major exception with eight forms; modal verbs like can and must have fewer.
Verbs carry tense (when), aspect (how it unfolds), mood (the speaker's attitude), and voice (active vs passive). Mastering them is foundational — virtually every other grammar topic depends on getting verbs right.
Past tense
The past tense is how English talks about events finished before now. It comes in four flavours: simple past (I walked) for completed events, past progressive (I was walking) for actions ongoing at a past time, past perfect (I had walked) for events before another past event, and past perfect progressive (I had been walking) for ongoing events leading up to a past point.
Choosing the right one is what makes past narratives clear instead of murky. When I arrived, she ate dinner is technically grammatical but means something different than had eaten (already done) or was eating (in progress when you arrived).
Progressive tense
The progressive aspect (also called continuous) marks an action as ongoing at the time of reference, formed with be + present participle (-ing): I am working, She was reading, They will be travelling. It signals temporary or in-progress events — the contrast with the simple aspect (I work = habit; I'm working = right now) is one of the most-used distinctions in English.
Some verbs (stative verbs like know, believe, own, belong) don't normally take the progressive — I'm knowing the answer sounds wrong. Recognising stative vs dynamic verbs is what stops you from over-applying the rule.
Simple tense
The simple aspect is the unmarked verb form — no progressive -ing, no have + past participle. I go, I went, I will go are simple; I am going, I have gone, I had gone are not. The simple aspect typically marks a single completed action (Brutus killed Caesar), a repeated/habitual action (I go to school every day), or a permanent state (We live in Dallas).
The simple aspect is the foundation everything else builds on. Once it's automatic, switching into progressive (ongoing) or perfect (completed-relative-to-now) becomes a small adjustment rather than a fresh decision.
Grammatical number
Grammatical number is the singular vs plural distinction marked on nouns, pronouns, and verbs. Most English nouns add -s or -es to form plurals (book → books, box → boxes), but a handful keep older patterns: child → children, foot → feet, mouse → mice, sheep → sheep. Pronouns swap forms entirely (I → we, he → they).
Number governs subject-verb agreement: He goes but They go. Mismatching subject and verb (The team are/is winning) is one of the most common slips in writing — and one that catches the attention of any careful reader.
Negation
Negation in English usually places not after the auxiliary or modal verb: I am not going, She does not know, You must not go. When there's no auxiliary, you add do-support: I go → I do not go. Most combinations contract: don't, can't, won't, isn't.
The trickiest rule for many learners: double negatives are not standard English. I didn't see nothing is non-standard; the standard forms are I saw nothing or I didn't see anything. Negative words like never, nobody, nothing already carry the negation — adding not on top doubles up.
Questions
Questions in English are typically formed by inverting the subject and an auxiliary verb: She can dance → Can she dance?. When there's no auxiliary present, English adds do-support: The milk goes in the fridge → Does the milk go in the fridge?. The same pattern handles wh-questions (Where do you live?) and negative questions (Doesn't he know?).
The trickiest variant is indirect questions — I wonder where he is, not where is he. The inversion drops because the question is embedded inside another clause. Getting this right is one of the bigger jumps from A2 to B1 fluency.
English Grammar Basics
The English Grammar Basics tag marks quizzes and explainers covering the foundations of English grammar — nouns, verbs, adjectives, adverbs, prepositions, conjunctions, tenses, voice, mood, and basic sentence structure.
If you're starting out or rebuilding from scratch, this is the tag to follow: every challenge under it is designed to land the core rules without burying you in exceptions. Get the basics solid here and the more advanced topics — conditionals, reported speech, inversion — stop looking like a wall of new rules and start looking like extensions of what you already know.
A1 | Elementary | Beginners
A1 is the starting level of the CEFR framework — the entry point into English. At A1 you can introduce yourself, ask and answer simple personal questions, recognise common signs and instructions, and have short slow-paced conversations on very familiar topics.
Grammatically, A1 covers the building blocks: present-tense forms of be, have, and do; basic word order; simple questions; and the most common determiners, pronouns, and prepositions. Knowing your level matters — A1 material teaches the foundations every later level builds on, while a B1 textbook will overwhelm you. Start here and progress is fast.
A2 | Elementary | Pre-intermediate
A2 is the elementary level in the CEFR framework, sitting between A1 and B1. At A2 you can handle routine exchanges — ordering food, asking directions, making small talk — and describe your immediate environment in simple sentences.
Grammatically, A2 introduces past simple and past continuous, present perfect for experiences, basic modal verbs, and the first conditional. You're also picking up collocations and learning which verbs take gerunds vs. infinitives. Knowing your level here is the difference between confident progress and frustration: A2 material consolidates the basics; B1 will overwhelm you.
Difficulty: Easy
The Easy difficulty tag marks questions and challenges aimed at beginners — typically A1 or early A2 level. Expect single-rule focus, short sentences, common everyday vocabulary, and one clear correct answer. Distractors usually rule themselves out quickly.
Filter by Easy when you're rebuilding fundamentals, warming up before harder material, or testing whether you've truly internalised a basic rule before moving on. Easy doesn't mean trivial — it means the rule itself is unambiguous and the context doesn't pile on extra complications.
