Help the suspicious human interrogate their strange new neighbor by dragging the correct words into the blanks.

Human: "Excuse me, how long has your spaceship been parked in my driveway?"

Neighbor: "Spaceship? Oh, you mean my car! Anyway, how long have you worn that ridiculous fake mustache?"

Human: "It's real! And I have had it for five days!"

Human: "Excuse me, how long has your spaceship been parked in my driveway?"

"Your spaceship" is a singular subject (it), so we use "has" along with the past participle "been".

Neighbor: "...how long have you worn that ridiculous fake mustache?"

Use "have" with "you," followed by the past participle "worn".

Human: "It's real! And I have had it for five days!"

Use "for" to describe a period or length of time (five days).

Perfect tense

  • I have lived here for ten years. — present perfect (started past, still true)
  • I live here for ten years. — wrong (simple present can't bridge past→now)
  • She had finished before I arrived. — past perfect (earlier past)
  • They will have left by noon. — future perfect (completed before future point)

The perfect = have + past participle. Connects an action to a reference point in time. Present perfect bridges past→now. Past perfect marks "earlier past." Future perfect marks "done before a future deadline."

Rule: if the action started in the past and is still relevant now → present perfect (have done). If two past events and you need the earlier one → past perfect (had done).

Questions

  • Do you like coffee? — do-support (no existing auxiliary)
  • Can she swim? — inversion (auxiliary before subject)
  • Where does he live? — wh-question
  • You're coming, aren't you? — tag question

Questions require inversion (auxiliary before subject) or do-support (add do/does/did). Types: yes/no (Do you…?), wh- (What/Where/When…?), negative (Don't you…?), tag (…isn't it?).

Rule: find the auxiliary. Move it before the subject. No auxiliary? Add do/does/did. Never use just intonation in written English (You like coffee? is not standard).

A2 | Elementary | Pre-intermediate

  • I went to the cinema yesterday. — past simple
  • I have visited Paris twice. — present perfect (life experience)
  • If it rains, I'll take an umbrella. — first conditional
  • You should see a doctor. — modal for advice

These patterns are A2 — the second CEFR level. At A2 you move past survival phrases into real grammar: past tenses, the present perfect, basic conditionals, and modals for advice/obligation.

Marker: if you can describe yesterday and give simple advice, but struggle with abstractions or nuance, you're at A2.

Easy

  • She is a teacher. — one verb form, one rule
  • I have two cats. — basic possession, short sentence
  • He doesn't like coffee. — simple negation with do-support
  • Only one answer is clearly correct; distractors are obviously wrong.

Easy marks beginner-level challenges: A1–early A2, one rule at a time, everyday vocabulary, no trick questions.

Use "Easy" when you want to build confidence on a specific rule without interference from other grammar or tricky contexts.
