Basics: Introduction to the Present Perfect
The present perfect tense connects the past to the present. We often use it to talk about life experiences without mentioning exactly when they happened, or to check if an action is complete. For example, you might ask, "Have you ever eaten sushi?" or state, "She has already finished her homework." It is formed using the auxiliary verb have or has combined with the past participle of the main verb.
In this challenge, you will explore everyday situations using the present perfect. You'll ask and answer questions about travel experiences, trying new carnival foods, watching sci-fi and vampire shows, and completing roommate chores. The exercises also cover essential grammar mechanics, including subject-verb agreement, irregular past participles, and forming interrogative (question) sentences for job interviews and airport luggage checklists.
You will work through 15 questions in a variety of formats, including single-choice, multi-choice, drop-down, and drag-and-drop.

"I know it's all over the internet right now, but have you actually seen the new vampire documentary?"
When asking if someone has experienced a piece of media up to the present moment, we use the Present Perfect. The structure is have + you + past participle (seen).
"I know we are at the state fair, but have you ever eaten deep-fried butter? It sounds terrifying!"

Drag the correct words to complete the travel blogger's excited social media post.
Welcome to my new travel blog! I am curious, have you ever flown in a hot air balloon? Or perhaps your family has visited the ancient pyramids in Egypt?
Welcome to my new travel blog! I am curious, have you ever flown in a hot air balloon? Or perhaps your family has visited the ancient pyramids in Egypt?
To ask about life experiences, we use "Have/Has + subject + past participle."
Have pairs with "you" and the irregular past participle flown.
"Family" acts as a singular collective group here, so it takes has along with the regular past participle visited.
Complete the travel agent's exciting question about a client's bucket list.
"Have you ever _____ in a hot air balloon over the mountains?"
The correct answer is flown.
The Present Perfect tense requires a past participle. The verb "fly" is irregular: its past tense is "flew", and its past participle is flown.
The correct answers are Have you ever eaten a deep-fried tarantula? and Have you ever met a famous actor?
When asking about life experiences, we use the present perfect: Have/Has + subject + past participle.
"Has you" is incorrect because "you" takes "have".
"Rode" is the simple past; the past participle of ride is "ridden" (Have you ever ridden...).
Drag the correct words to help the suspicious roommate complete their interrogation.
Tell me the truth, have you eaten my leftover pizza? Also, I want to know if Dave has taken my favorite coffee mug!
Tell me the truth, have you eaten my leftover pizza? Also, I want to know if Dave has taken my favorite coffee mug!
When forming questions in the present perfect, we use the auxiliary verb have for "you" and pair it with a past participle (like eaten).
For a third-person singular subject like "Dave", we use has plus the past participle (like taken).
The correct answers are Have you ordered the pizzas yet? and Have you already cleaned the bathroom?
We often use the present perfect to ask about recent actions or things on a checklist.
"Did you finished" is incorrect because "did" requires the base verb ("finish"), but "yet" usually pairs better with the present perfect anyway (Have you finished...?).
"Has the DJ arrive" is missing the past participle (Has the DJ arrived?).
"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.
The correct answers are Have you ever swum with sharks? and Have you ever slept in an igloo?
The present perfect requires a past participle.
"Flew" is the simple past of fly; the past participle is "flown" (Have you ever flown...?).
"Rode" is the simple past of ride; the past participle is "ridden" (Have you ever ridden...?).
"Swum" and "slept" are correct past participles!
Complete the foodie's curious question to their brave friend.
"_____ ever eaten a deep-fried grasshopper? I hear they taste like chicken!"
The correct answer is Have you.
To ask about someone's life experiences up to the present moment, we use the Present Perfect tense. We form questions with Have + subject + past participle (e.g., Have you eaten...?).
The correct answers are Has the main suspect confessed? and Have the witnesses spoken to the chief?
The auxiliary verb must agree with the subject!
"The security guard" is singular, so it needs "Has" (Has the security guard checked...?).
"The fingerprints" is plural, so it needs "Have" (Have the fingerprints been analyzed?).
Drag the correct words to help the confused interviewer verify the candidate's unusual resume.
Looking at your resume, I must ask: have you really trained a flock of pigeons to deliver mail? Furthermore, has your previous boss actually written this glowing recommendation in invisible ink?
Looking at your resume, I must ask: have you really trained a flock of pigeons to deliver mail? Furthermore, has your previous boss actually written this glowing recommendation in invisible ink?
The present perfect is perfect for checking past experiences with a connection to the present (like a resume!).
We use have with "you" and the regular past participle trained.
For the singular subject "boss", we use has and the irregular past participle written.
Choose the correct response to the coffee shop manager's interview question.
"Have you ever operated a commercial espresso machine before?" "No, _____."
The correct answer is I haven't.
When answering a "Have you...?" question, we use short answers with the same auxiliary verb. The negative short answer for "I" is No, I haven't (have not).
"The flight landed an hour ago! Have your parents found their luggage yet?"
"Parents" is a plural subject (they), so we use the auxiliary verb Have. For the main verb, we need the past participle of "find," which is the irregular verb found.
Help the sci-fi fan ask a very important question.
"_____ a UFO hovering in your backyard?"
The correct answer is Have you ever seen.
In Present Perfect questions, the auxiliary verb Have comes before the subject (you). The word ever (meaning "at any time in your life") goes right before the past participle (seen).
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.
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.
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.
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.
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.
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.
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.
