Choose the correct adverb to complete the art student's critique of a modern painting.
The artist’s late geometric period was _____ influenced by the architecture of the industrial cities she visited in her youth.
The correct answer is heavily.
"Heavily" is the natural adverb to use with "influenced" or "reliant" when describing a strong effect or impact. While words like "strictly" or "fiercely" are valid adverbs, they do not form a natural collocation with "influenced."
Adjective and adverb
- ✅ a quick response — ❌ a quickly response
- ✅ she spoke quietly — ❌ she spoke quiet
- ✅ the food tastes good — ❌ the food tastes well
- ✅ he runs fast — ✅ a fast car (same word, both roles)
Adjectives modify nouns; adverbs modify verbs, adjectives, or other adverbs. Most adverbs add -ly to the adjective (slow → slowly), but some words — fast, hard, late — serve as both without changing form.
Rule: if the word describes a noun → adjective. If it describes an action or degree → adverb.
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.
Passive voice
- ✅ The meal was cooked by the chef. — passive (action matters)
- ✅ Mistakes were made. — passive, agent hidden (evasive)
- ✅ Active: The chef cooked the meal. — stronger, clearer
- ❌ The report was being been written. — malformed passive
The passive = be + past participle. Object becomes subject. Use it when the doer is unknown, irrelevant, or obvious. Avoid when it hides responsibility or weakens prose.
Formula: find the active object → make it the subject → use be (matching tense) + past participle → optionally add by + agent.
Participle
- ✅ a broken window — past participle as adjective
- ✅ the running water — present participle as adjective
- ✅ I have eaten. — past participle in perfect tense
- ✅ She is sleeping. — present participle in progressive tense
- ❌ I have went. — wrong (past tense, not past participle: use gone)
A participle is a verb form that also works as an adjective. Present (-ing): running, sleeping. Past (-ed or irregular): broken, written, gone. Used in progressive tenses, perfect tenses, passive voice, and as modifiers.
Trap: don't confuse past tense (went) with past participle (gone). After have/has/had → always past participle.
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.
Vocabulary for B2/Upper Intermediate
- Register precision: big → substantial, considerable, significant
- Hedging: tend to, somewhat, arguably, to some extent
- Reporting verbs: claim, argue, suggest, acknowledge, deny
- Idiomatic: break the ice, out of the blue, get the hang of
B2 vocabulary = ~4,000–6,000 words. Register awareness, hedging, reporting verbs, idioms, figurative expressions. Grammar is no longer the limit — precision of word choice is.
Focus: synonyms with different registers (begin/commence/start), hedging language for academic writing, and the reporting verbs that distinguish said from claimed/argued/insisted.
B2 | Upper Intermediate
- ✅ If I had studied harder, I would have passed. — third conditional
- ✅ The report is being reviewed by the committee. — passive progressive
- ✅ Having finished the exam, she left. — participle clause
- ✅ He denied having taken the money. — complex verb pattern
These are B2 patterns — the CEFR upper-intermediate level. At B2 you handle mixed conditionals, all passive forms, participle clauses, and can argue a point clearly. This is the level most universities and employers require.
Marker: if you can write a structured essay and debate an abstract topic, you're B2.
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.
