Help the stressed-out wedding planner complete her frantic text messages to her assistant by dragging the correct verb forms into the gaps.
I finally managed to get the stubborn caterer to change the menu, but it took an hour of arguing! Now, we need to have the backup floral arrangements delivered to the reception hall by noon, or the bride will absolutely panic. Also, please check on the best man—if he keeps arguing with the DJ, he's going to get himself kicked out of the venue before the ceremony even starts!
I finally managed to get the stubborn caterer to change the menu...
The active causative with "get" follows the pattern get + object + to-infinitive (meaning to persuade or convince someone to do something).
...we need to have the backup floral arrangements delivered to the reception hall...
The causative passive with "have" follows the pattern have + object + past participle (meaning to arrange for a service to be done to an object).
...he's going to get himself kicked out of the venue...
The reflexive get-passive uses get + oneself + past participle to describe a situation where a person's own actions cause something (usually negative) to happen to them.
Passive voice
Active vs passive: active puts the doer first (The dog bit the man). Passive puts the receiver first (The man was bitten by the dog). Neither is inherently wrong — choice depends on what you want to foreground. Scientific/formal writing uses passive deliberately; vague writing uses it accidentally.
Passive voice = be + past participle. Promotes the object to subject. Good for foregrounding the action/result; bad when it hides who's responsible.
Diagnostic: who's doing the action? If unnamed and that matters → bad passive. If unnamed because it's obvious or irrelevant (The building was constructed in 1920) → good passive.
Infinitive
Infinitive vs gerund: the #1 verb-pattern confusion. Some verbs take only infinitive (want to go ✅), some only gerund (enjoy going ✅), some both with different meanings (stop to smoke ≠ stop smoking). No logical rule exists — learn by verb.
The infinitive = base verb form used non-finitely. To-infinitive (to go) after certain verbs. Bare infinitive (go) after modals and causatives.
Diagnostic: what's the main verb? Check whether it takes to-infinitive, bare infinitive, or gerund. If unsure, try both and see which sounds natural to native speakers.
Participle
Present participle vs gerund: both are -ing forms, but a participle acts as an adjective/adverb (the running water, She sat reading), while a gerund acts as a noun (Running is fun). Same form, different grammatical job.
A participle = verb form used as modifier or in compound tenses. Present (-ing): progressive + adjective. Past (-ed/irregular): perfect + passive + adjective.
Diagnostic: is the -ing word describing a noun or modifying a verb? → participle. Is it being a noun (subject, object)? → gerund.
Verb
Verb vs noun vs adjective: nouns name things. Adjectives describe. Verbs express what happens or what IS. The test: can it take tense (walked, will walk)? Can it take -ing? Can it follow to as an infinitive (to walk)? Yes to any → verb. English often converts freely between classes (run = noun or verb), so context decides.
A verb = action/state/occurrence word. 5 forms (base, -s, past, past participle, -ing). Carries tense, aspect, mood, voice. The one required element in every sentence.
Diagnostic: does it change for tense (walk → walked)? Can you put to before it (to walk)? Does it take -ing (walking)? → verb.
C1 | Advanced
C1 vs C2: C1 means fluent and flexible use with occasional gaps in very unfamiliar domains. C2 means native-like command of idiom, irony, and register across any subject. If you can handle advanced grammar but still miss cultural nuance or very rare idioms, you're C1.
C1 is the advanced CEFR level: inversion, cleft sentences, subjunctive mood, advanced conditionals, and precise register control in professional and academic contexts.
Diagnostic: can you write persuasively in different registers and catch subtle irony? Consistently → C2. Sometimes → C1.
Hard
Hard vs Medium: Medium tests one rule with realistic distractors. Hard tests interacting rules, edge cases, or context-dependent answers where multiple options seem correct until you think deeply. If you're scoring 80%+ on Medium, try Hard to find your real gaps.
The Hard tag filters for B2+ challenges with layered difficulty: rule interactions, subtle distractors, and contexts that demand genuine grammatical reasoning.
Diagnostic: if Hard questions feel impossible, drop to Medium and master the individual rules first. Hard assumes you already know each rule — it tests whether you can apply them together.
