Help the frustrated roommate complete their complaint.

My roommate ___ the pizza when he cooks dinner.

The correct answer is often burns.

Adverbs of frequency like often belong before the main verb (burns). Because "roommate" is a singular subject (he/she), we must use the verb form ending in "s" (burns).

To ChallengesPreviousNext

Adverb

  • She sings beautifully — ❌ She sings beautiful
  • He drives carefully — ❌ He drives careful
  • They arrived late — ✅ a late train (same form, both roles)
  • She works hard — ❌ She works hardly (different meaning!)

The -ly words are adverbs — they modify verbs, adjectives, or other adverbs, telling you how, when, where, or to what degree.

Pattern: most adjectives become adverbs by adding -ly, but watch the exceptions — fast, hard, late, well — that keep the same shape or change meaning entirely.

Word order

  • She (S) eats (V) cake (O). — standard SVO
  • Cake eats she. — SOV (not English)
  • a lovely little old rectangular green French silver whittling knife — adjective order (opinion→size→age→shape→colour→origin→material→purpose)
  • Never have I seen…inversion after negative adverb

English word order = SVO (subject-verb-object) as default. Adjectives follow a fixed sequence (opinion→size→age→shape→colour→origin→material). Adverb placement varies by type. Deviations signal questions, emphasis, or literary style.

Rule: when in doubt, default to SVO. English position = meaning. Move a word and you change the grammar or the emphasis.

Present tense

  • I work here. — simple present (habit/permanent)
  • I am working now. — present progressive (happening right now)
  • I have lived here for 10 years. — present perfect (started past, still true)
  • I have been waiting for an hour. — present perfect progressive (duration up to now)

Four present tense forms: simple (habits/facts), progressive (now/temporary), perfect (past → present relevance), perfect progressive (ongoing duration). Each encodes a different relationship between the action and the present moment.

Trap: "I am living here for 10 years" ❌ — started in the past + still true = present PERFECT (have lived/have been living), not progressive.

Simple tense

  • I go to work every day. — present simple (habit)
  • She went home yesterday. — past simple (completed action)
  • I will call you later. — future simple (promise/decision)
  • Water boils at 100°C. — present simple (general truth)

The simple aspect is the default, unmarked verb form. Present simple = habits, facts, schedules. Past simple = completed actions. Future simple = predictions, promises, decisions. No auxiliary needed (except will for future and do for questions/negatives).

Rule: if the action is a fact, habit, completed event, or scheduled future — and you don't need to emphasise it being in-progress or connected to now → simple tense.

Subject

  • The list of items is wrong. — subject = list (singular), not items
  • The list of items are wrong. — trapped by nearest noun
  • Running is good exercise. — gerund as subject
  • What he said surprised me. — clause as subject

The subject is the noun/pronoun/phrase before the verb that controls its number and person. Finding the true subject — especially through prepositional phrases — is the key to subject-verb agreement.

Rule: strip away prepositional phrases between subject and verb. Whatever's left is the true subject. The list (of items) is wrong.

A1 | Elementary | Beginners

  • My name is Anna. — present simple of be
  • Where is the station? — basic *wh-*question
  • I have two brothers. — possession with have
  • She likes coffee. — third-person -s

These are A1 sentences — the starting level of the CEFR framework. At A1 you can introduce yourself, ask and answer simple personal questions, and handle basic everyday transactions using present tense, be/have/do, and core vocabulary.

If you can say these but freeze at normal speaking speed, you're solidly A1 — and that's exactly where to start.

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.
