Complete the tired roommate's text message about their new living situation.

"I read online that ___ sleep for 15 hours a day, but mine just runs around at 3 AM knocking things off the counter!"

The correct answer is cats.

When talking about things in general using plural nouns, English uses the zero article (no article). Romance languages usually use the definite article for general statements (like Los gatos... or Les chats...), but in English, we just say cats.

Article

  • an hour — ❌ a hour (vowel soundan)
  • a university — ❌ an university (consonant sound /j/ → a)
  • I love coffee — ❌ I love the coffee (generic uncountable → zero article)
  • the sun — ❌ a sun (unique referent → the)

Articles (a/an, the, and the zero article) signal whether a noun is specific or general. A/an introduces something new; the points to something already known or unique.

Pattern: a/an = "one of many, first mention." The = "you know which one." Zero article = generic or uncountable.

Noun

  • The cat sat on the mat. — concrete nouns (things you can touch)
  • Happiness is important. — abstract noun (idea/quality)
  • London is beautiful. — proper noun (specific name, capitalised)
  • I need some information.uncountable noun (no a/an, no plural)

A noun names a person, place, thing, idea, or quality. Nouns determine article choice, verb agreement, and pronoun reference. Types: common/proper, concrete/abstract, countable/uncountable.

Test: can you put the or a before it? Can you make it plural? If yes to either → it's functioning as a noun.

Determiner

  • The cat sat on a mat. — articles as determiners
  • My sister has three dogs. — possessive + numeral as determiners
  • I went to the home. — wrong (idiomatic: I went home — no determiner)
  • She is a good student. ✅ vs She is good student. ❌ — missing determiner

A determiner sits before a noun to specify which, how many, or whose. Types include articles, demonstratives, possessives, and quantifiers.

Rule: most singular countable nouns in English require a determiner — a cat, the cat, my cat, this cat. Dropping it (cat sat on mat) breaks the sentence.

Countable and uncountable

  • some advice — ❌ an advice / advices (uncountable → no article, no plural)
  • a piece of furniture — ❌ a furniture / furnitures
  • How much water? — ❌ How many water? (uncountable → much)
  • fewer people — ❌ less people (countable plural → fewer)

English nouns are either countable (take a/an, form plurals, use many/few) or uncountable (no plural, use much/little). The choice is partly arbitrary and must be memorised.

Test: can you put a number in front? Three chairs → countable. Three furnitures ❌ → uncountable. Use a unit phrase instead: three pieces of furniture.

B1 | Intermediate

  • If I had more time, I would travel more. — second conditional
  • The bridge was built in 1920. — passive voice
  • She said she was tired. — reported speech with backshift
  • Although it rained, we enjoyed the trip. — complex sentence with concession

These are B1 patterns — the CEFR intermediate level. At B1 you link ideas, use passive voice, handle reported speech, and manage second conditional — enough for travel, work basics, and everyday independence.

Marker: if you can explain why something happened and follow a news story, you're B1.

Medium

  • If I were you, I would apologise. — one rule (second conditional), but distractors like was tempt you
  • Answers require active thought, not instant pattern recognition
  • Vocabulary and context are realistic, not artificially simplified
  • Usually tests one rule, but the wrong answers are plausible

Medium marks middle-difficulty challenges: A2B1, one rule tested, but with realistic distractors that require genuine understanding.

Use "Medium" when Easy feels too obvious but Hard feels overwhelming. This is where most productive learning happens — the sweet spot of difficulty.
