Verbs with Gerunds and Infinitives: Meaning Changes
In English, some verbs can be followed by either a gerund (an -ing word) or an infinitive (to + verb). While verbs like "start" or "continue" mean the same thing either way, a special group of verbs completely changes meaning depending on which form you choose. For example, "I stopped to drink coffee" means you paused your journey in order to have a drink, but "I stopped drinking coffee" means you quit the habit entirely.
Inside this challenge, you will practice navigating these tricky double-meaning verbs. You'll help a detective review witness statements, advise an office worker battling a broken printer, and complete an astronaut's diary by choosing the correct forms for the verbs stop, remember, forget, try, and regret.
This challenge features 10 questions in a mix of single-choice, multi-choice, drop-down, and drag-and-drop formats. Try the quiz to check your knowledge!
Gerund
A gerund is the -ing form of a verb used as a noun: swimming, reading, being late. It can sit in any position a noun can: as the subject (Swimming is fun), as the object of a verb (I enjoy swimming), or as the complement of a preposition (She's good at swimming).
Gerunds matter because dozens of common English verbs and almost every preposition force you into the -ing form. Pick the wrong shape (I enjoy to swim, good at to swim) and the sentence sounds clearly off to a native speaker. Knowing which contexts demand a gerund (vs. an infinitive) is what makes verb patterns click.
Infinitive
The infinitive is the basic, unmarked form of a verb, used when no tense or subject agreement is needed. English has two flavors: the to-infinitive (to swim, to read) and the bare infinitive (swim, read). The to-infinitive follows verbs like want, decide, hope, plan (I want to swim); the bare infinitive follows modal verbs (I can swim) and certain causative verbs (Let him go).
Knowing which form to use after which verb is one of the trickiest distinctions in English, closely tied to the parallel choice of gerund (-ing form). I want to swim but I enjoy swimming aren't interchangeable.
Past tense
The past tense is how English talks about events finished before now. It comes in four flavors: simple past (I walked) for completed events, past progressive (I was walking) for actions ongoing at a past time, past perfect (I had walked) for events before another past event, and past perfect progressive (I had been walking) for ongoing events leading up to a past point.
Choosing the right one is what makes past narratives clear instead of murky. When I arrived, she ate dinner is technically grammatical but means something different than had eaten (already done) or was eating (in progress when you arrived).
Verb
A verb is a word that expresses an action, a state, or an occurrence: the engine of every English sentence. Most verbs have five forms: base (go), -s form (goes), past tense (went), past participle (gone), and -ing form (going). The verb be is the major exception with eight forms; modal verbs like can and must have fewer.
Verbs carry tense (when), aspect (how it unfolds), mood (the speaker's attitude), and voice (active vs passive). Mastering them is foundational: virtually every other grammar topic depends on getting verbs right.
Simple tense
The simple aspect is the unmarked verb form: no progressive -ing, no have + past participle. I go, I went, I will go are simple; I am going, I have gone, I had gone are not. The simple aspect typically marks a single completed action (Brutus killed Caesar), a repeated/habitual action (I go to school every day), or a permanent state (We live in Dallas).
The simple aspect is the foundation everything else builds on. Once it's automatic, switching into progressive (ongoing) or perfect (completed-relative-to-now) becomes a small adjustment rather than a fresh decision.
B1 | Intermediate
B1 is the intermediate level in the CEFR framework, the point where you stop relying on memorized phrases and start handling everyday English independently. At B1 you can describe experiences, explain opinions, and follow most clear standard speech on familiar topics like work, travel, and hobbies.
Grammatically, B1 means combining tenses with precision, building complex sentences, and starting to use passive voice, modal verbs for necessity and possibility, and verb patterns (gerund vs. infinitive). Knowing your level shapes what you study next: pushing too far ahead frustrates you; staying below your level wastes time.
Difficulty: Medium
The Medium difficulty tag marks questions and challenges in the middle of the difficulty range, typically suitable for A2 to B1 learners. Expect a single rule with realistic distractors, longer sentences, and contexts where you have to think before answering rather than reading off the obvious choice.
Filter by Medium when you're past the absolute basics and ready to consolidate. It's the level where most lasting progress happens: easy enough that you can finish without exhausting concentration, hard enough that getting it right means you've actually understood.
