This second gerund or infinitive exercise includes several pairs of sentences using the same verb — once requiring the gerund, once requiring the infinitive — to help you feel the difference in context. Start with exercise 1 if you haven't already.
Fill in each space with either the gerund ("-ing") or the infinitive form of the verb in parentheses.
Example: "Reading in the dark is difficult. (to read)" OR
"Don't forget to brush your teeth." (to brush)
This exercise features several sentence pairs that show the same verb used with both a gerund and an infinitive. Understanding why each form is correct is more useful than just memorizing lists.
When the same verb triggers both forms with the same meaning:
Some verbs — like, love, hate, start, begin, continue — take either form without a change in meaning: I've always wanted to visit Australia. (want + infinitive) I've always dreamed of visiting Australia. (preposition of + gerund)
The preposition rule — the most reliable rule in this area:
After any preposition, always use the gerund. No exceptions. interested in moving / good at drawing / think about leaving / plan on buying / dream of visiting
Watch out for "forget" and "don't forget": Don't forget to clean the kitchen. → infinitive (reminder about a future action) Don't forget about cleaning the kitchen. → gerund after preposition about
Both are correct — the structure before the verb determines the form.
DID YOU KNOW? Gerunds vs. infinitives across languages
Most languages don't have a gerund/infinitive distinction the way English does — which is a big part of why it's so difficult for ESL learners. In Spanish, French, Italian, and Portuguese, the infinitive does most of the work that both forms do in English: J'aime nager (French) and Me gusta nadar (Spanish) both use the infinitive to say "I enjoy swimming" — so speakers of these languages often default to the infinitive in English even when the gerund is required.
In contrast, German has a strong gerund-like construction and speakers often over-apply the -ing form. Mandarin Chinese handles verbal nouns completely differently and has no direct equivalent of either form, making both equally unfamiliar.
The good news: research in second language acquisition suggests that verb-by-verb exposure — exactly what exercises like this provide — is the most effective way to internalize these patterns. Trying to memorize rules alone rarely works; seeing the verbs in natural context is what makes them stick.
