"The guests are arriving in twenty minutes! Has Mark cleaned the living room yet?"
We use the Present Perfect to ask if a recent action is finished. Because "Mark" is a singular third-person subject (he), we use Has, followed by the past participle cleaned.
Perfect tense
The perfect aspect marks an action as complete relative to a point in time. It's formed with have + past participle: I have eaten (present perfect), She had finished (past perfect), They will have arrived (future perfect). The perfect doesn't just say when — it says the action's completion is relevant to the time of reference.
The trickiest English-specific use is the present perfect: I have lived in Paris connects the past to now (you may still live there), while I lived in Paris doesn't. This connection is one of the biggest jumps for learners whose native language doesn't make the same distinction.
Present tense
The present tense in English has four forms: simple present (I work) for habits, general truths, and stative descriptions; present progressive (I am working) for actions happening right now or temporary situations; present perfect (I have worked) for past actions with present relevance; and present perfect progressive (I have been working) for ongoing actions continuing into the present.
The simple/progressive distinction is one of the trickiest jumps for learners — I work in Paris (habitual) and I'm working in Paris (temporary, right now) feel almost identical but signal different things. Pick wrong and your meaning subtly shifts.
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.
Habits and routines
The Habits and routines tag covers questions about regular actions and daily routines: I brush my teeth every morning, She usually has coffee at 8am, We always go to the gym on Saturdays. The grammar core is the present simple for habits, adverbs of frequency (always, usually, sometimes, never), and time expressions (every day, on Mondays, twice a week).
For past habits, English uses used to and would (I used to live in Berlin; Every summer we would go to the lake). Getting these right is the difference between describing your life clearly and stumbling through every introduction.
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.
