Finish the pet owner's funny text message to their friend. Select the grammatically correct option.
My dog Buster loves playing in the mud all day, but he is absolutely afraid of _____ a bath.
The correct answer is taking.
When we use the adjective "afraid" followed by the preposition "of", any verb that comes next must be a gerund (the "-ing" form). So, "afraid of taking" is the correct choice!
Gerund
- ✅ I enjoy reading. — ❌ I enjoy to read.
- ✅ She's good at swimming. — ❌ She's good at to swim.
- ✅ He avoids making eye contact. — gerund after avoid
- ✅ Running is good exercise. — gerund as subject
A gerund is the -ing form of a verb functioning as a noun. It follows verbs like enjoy, avoid, finish, mind and ALL prepositions. Never use an infinitive where a gerund is required.
Rule: after a preposition (at, in, of, about, without) → always gerund. After enjoy, avoid, finish, mind, suggest, deny → always gerund.
Preposition
- ✅ interested in — ❌ interested on
- ✅ good at football — ❌ good in football
- ✅ depend on — ❌ depend of
- ✅ arrive at the station — ❌ arrive to the station
Prepositions link nouns to the rest of the sentence: time (at 5pm), place (in London), manner (with care), abstract (afraid of). Most are idiomatic — the "correct" preposition must be memorised with each verb/adjective combination.
Rule: there is no universal rule. English prepositions are learned by combination: interested IN, good AT, depend ON, afraid OF. Your native language's equivalent will often mislead.
Adjective
- ✅ a tall building — ❌ a tally building
- ✅ The soup is hot — ❌ The soup is hotly
- ✅ a lovely small old table — ❌ a small lovely old table
- ✅ She seems tired — ❌ She seems tiredly
These bolded words are adjectives — words that describe nouns or pronouns. They sit before a noun (a tall building) or after a linking verb (The soup is hot).
Pattern: if a word can slot between a/the and a noun (a ___ thing) and can take -er/-est, it's almost certainly an adjective.
Collocations
- ✅ make a decision — ❌ do a decision
- ✅ strong coffee — ❌ powerful coffee
- ✅ heavy rain — ❌ strong rain
- ✅ highly unlikely — ❌ very unlikely (grammatical, but less natural)
Collocations are word pairs that English habitually puts together. Both options may be grammatically valid, but one sounds native and the other doesn't.
Pattern: there's no logic to predict them — you make decisions but do homework, you have strong coffee but heavy rain. They must be learned as chunks, not deduced from rules.
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.
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: A2–B1, 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.
