The incriminating financial records were ordered to be destroyed just hours before the auditors arrived. Now, the former CEO is reported to have been arrested while trying to flee to a tropical island.
The incriminating financial records were ordered to be destroyed just hours before the auditors arrived. Now, the former CEO is reported to have been arrested while trying to flee to a tropical island.
In the first sentence, the records did not issue an order or destroy anything themselves; they received the action. Therefore, both verbs must be passive: were ordered (main verb) and to be destroyed (infinitive).
In the second sentence, the CEO is the subject of the passive reporting verb is reported. Because the arrest already happened, we use the perfect passive infinitive to have been arrested. Using the active "to have arrested" would incorrectly imply the CEO arrested someone else!
Passive voice
If your writing has been called "weak" or "evasive" — Mistakes were made, It was decided that... — you've hit the passive voice's main pitfall. Used deliberately, the passive is precise and useful: it foregrounds the action when the doer doesn't matter. Used by default, it makes prose feel like nobody's responsible for anything.
The passive voice is formed with be + past participle and turns the object into the subject: The chef cooked the meal → The meal was cooked (by the chef). Useful when the action matters more than the doer; overused, it makes writing feel evasive.
Infinitive
If you've ever written I enjoy to swim or He let me to go and only later learned why both are wrong — you've hit the infinitive's main puzzle. English is fussy: some verbs demand the to-infinitive, some demand the bare infinitive, some demand the gerund, and a few accept multiple options with different meanings (remember to lock vs remember locking).
The infinitive is the basic form of a verb, used non-finitely. The to-infinitive (to go) follows verbs like want, decide, plan; the bare infinitive (go) follows modal verbs (can, will) and causatives (Let him go).
Perfect tense
If you've ever written I am living here for ten years (should be have lived or have been living) — you've hit the perfect tense's main puzzle. English insists that "started in the past, still true now" lives in the present perfect, not the simple present. Get this clear and a whole class of common errors disappears.
The perfect aspect marks completion relative to a point in time, formed with have + past participle: I have eaten (present perfect), She had finished (past perfect), They will have arrived (future perfect). Combinable with progressive aspect (I have been working).
Verb
If grammar feels overwhelming, the fix is almost always to focus on verbs first. They carry the action, the time, the mood, and the voice — a single verb form decides whether your sentence reads as past or present, fact or hypothetical, active or passive. Get verbs solid and the rest of grammar suddenly looks much smaller.
A verb expresses action, state, or occurrence — the engine of every English sentence. Most verbs have five forms (base, -s, past tense, past participle, -ing); be has eight; modal verbs have fewer. Verbs carry tense, aspect, mood, and voice.
Phrase
If you've ever read a long sentence in English and felt lost in the middle, you've hit a sentence with too many phrases stacked together. Learning to spot phrases — on the table, the man with the hat, very quickly — turns dense prose into something you can parse: each phrase is one chunk of meaning, not a string of unrelated words.
A phrase is a group of words functioning as a single unit in a sentence, without a subject + verb pair (which would make it a clause). Types include noun phrase (the red car), verb phrase (has been running), prepositional phrase (on the table), and adjective/adverb phrases.
C2 | Proficiency
If you can argue a point in English, then switch register to comfort someone, then crack a joke that lands — without thinking about which words to choose — you're operating in C2 territory. Most learners don't need to reach this level. The reason it matters is the opposite: knowing C2 exists stops you from setting it as the bar when B2 or C1 is more than enough for what you actually want to do.
C2 is the proficiency level — the highest on the CEFR scale. It means near-native control of idiomatic range, register-switching, irony, and complex written argument across any subject.
Difficulty: Hard
If easy and medium questions are clicking but you still feel exposed in real conversation or formal writing, you've outgrown the basics. Hard material is where the gaps you didn't know you had show up: the distractor that "sounds right", the rule that interacts with another rule, the case where context changes the answer. It's where genuine fluency is built.
The Hard difficulty tag marks upper-intermediate to advanced challenges — typically B2 and above. Interacting rules, edge cases, plausible distractors, and contexts that require genuine understanding rather than surface pattern-matching.
