2.14. Look at “-ing” words in bold type in Text B. Do they function like nouns?
Do you know that…?
A Verb + “-ing” that functions like a noun is a gerund.
Some verbs that can be followed by a gerund:
Admit avoid consider deny enjoy finish start continue miss practise suggest (dis)like keep mind miss recommend resist understand
Gerund is also follows after prepositions (like a noun). (e.g. He’s interested in working with students.)
A gerund can be the subject of a sentence. (e.g. Working too long on a computer is bad for your eyes.)
A gerund can also be the object of certain verbs. (e.g. I enjoy surfing the Web).
It is possible to turn a verb (phrase) into the object of certain other verbs by putting it into the –ing form words (e.g. instead of ‘Sarah reads a lot; she likes it’ we can say ‘Sarah likes reading’ and instead of ‘Jack plays a lot of computer games; he enjoys it’ we can say ‘Jack enjoys playing computer games’).
