Choose the correct phrase to complete the narrator's description of Captain Pajamas.
Despite the city being under attack by giant mutant hamsters, the sleepy hero was quite reluctant ___ his cozy blankets.
The correct answer is to leave.
Adjectives that describe a person's willingness, readiness, or hesitation (like reluctant, eager, willing, or hesitant) take a to-infinitive to show what action they are (or aren't) prepared to do.
Adjective
If you've ever written a French nice old wooden table and felt something was wrong without knowing why, you've hit the adjective-order rule. English insists on a particular sequence — opinion, size, age, shape, colour, origin, material — and rearranging the words makes a sentence sound non-native even when every individual choice is correct.
An adjective describes a noun or pronoun: a tall building, the soup is hot. Most adjectives also take comparative and superlative forms (taller, tallest), which is how you compare things — another core piece you need from day one.
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).
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.
B1 | Intermediate
If you can hold a conversation about your weekend, explain why you're late, and follow a short news story without panicking — but still feel lost in fast or technical English — you're probably operating at B1. Knowing this matters: study material at the wrong level either bores you or burns you out, and B1 is the typical target for travel, casual work, and most everyday social English.
B1 is the intermediate level in the CEFR framework, where you handle everyday English independently and start combining ideas with complex sentences, passive voice, and modal verbs.
Difficulty: Medium
If easy questions feel too obvious but hard questions leave you guessing, you're probably ready for Medium — the level where most real learning happens. It pushes just enough to expose the rules you don't quite have yet, without burying you in edge cases. This is where steady fluency is built, one well-aimed challenge at a time.
The Medium difficulty tag marks middle-range challenges — typically A2 to B1. One rule per question, realistic distractors, and contexts that require active thought rather than instant recognition.
