Complete the royal historian's dramatic account of the rebellion. Choose the correct verb phrase to show that the knight was the recipient of both the command and the punishment.
To serve as a warning to other traitors, the captured knight _______________ at dawn.
The correct answer is was commanded to be executed.
This is a classic double passive. The knight receives the command (was commanded — simple past passive) and is also the one receiving the punishment (to be executed — passive infinitive).
If we used "was commanded to execute," it would mean the knight was ordered to kill someone else. If we used "commanded to be executed," the sentence would be missing its main auxiliary verb ("was") or it would imply the knight gave the command himself.
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.
Infinitive
- ✅ I want to go. — to-infinitive after want
- ✅ She can swim. — bare infinitive after modal
- ✅ Let me help. — bare infinitive after let
- ❌ I enjoy to read. — wrong (enjoy takes gerund, not infinitive)
The infinitive has two forms: to-infinitive (to go) after verbs like want, decide, plan, hope; bare infinitive (go) after modals and causatives (let, make, help).
Rule: after want, need, decide, plan, hope, expect, agree, refuse → to-infinitive. After can, will, must, let, make → bare infinitive. After enjoy, avoid, finish → gerund, NOT infinitive.
Past tense
- I walked home. — simple past (completed action)
- I was walking when it rained. — past progressive (in progress)
- I had already left when she arrived. — past perfect (earlier past)
- I had been waiting for an hour. — past perfect progressive (duration up to a past point)
Four past tense forms: simple past (done), past progressive (was happening), past perfect (had already happened), past perfect progressive (had been happening). Each encodes different timing relative to other past events.
Pattern: simple past = the story's main timeline. Past progressive = background action. Past perfect = flashback to something even earlier.
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.
Phrase
- the red car — noun phrase (functions as one noun unit)
- on the table — prepositional phrase
- has been running — verb phrase
- very quickly — adverb phrase
A phrase is a group of words that functions as a single unit WITHOUT a subject + verb pair. Types: noun phrase, verb phrase, prepositional phrase, adjective phrase, adverb phrase.
Key distinction: a phrase lacks a subject-verb pair. If it has subject + verb → it's a clause, not a phrase. Phrases are the building blocks clauses are made of.
C2 | Proficiency
- ✅ His was a pyrrhic victory, if ever there was one. — literary allusion + inversion
- ✅ She'd have been none the wiser had he not let slip. — inverted conditional + idiom
- ✅ The proposal, laudable though it may be, fails on pragmatic grounds. — formal concession
- ✅ "Nice weather," he deadpanned, eyeing the hailstones. — irony + narrative register
These are C2 patterns — the highest CEFR level. At C2 you handle literary allusion, irony, any register, and complex written argument with native-like precision across all subjects.
Marker: if your English is indistinguishable from an educated native speaker's across registers, you're C2.
Hard
- Had she not intervened, the situation would have escalated. — inverted conditional
- All distractors are grammatically plausible in other contexts
- Multiple rules interact (e.g., tense + aspect + modality)
- Context determines the answer — no single "rule" is enough
Hard marks upper-intermediate to advanced challenges: B2+, interacting rules, edge cases, plausible distractors, and contexts where pattern-matching fails.
Use "Hard" when Easy/Medium feel trivial and you want to test whether you actually understand a rule versus just recognising surface patterns.
