Introduction of GerundThe -ing form of the verb may bea present participle or a gerund.The form is identical, the difference is in the function, or the job the word does in the sentence.
The gerund:This always has the same function as a noun (although it looks like a verb), so it can be used:• as the subject of the sentence: e.g. Eating people is wrong.• after prepositions: e.g. She is good at painting.• after certain verbs, e.g. like, hate, admit, imagine• in compound nouns, e.g. a driving lesson, a swimming pool, bird- watching, train-spotting
THE GERUNDThis looks exactly the same as a present participle,and for this reason it is now common to call bothforms the -ing form. However it is useful tounderstand the difference between the two. Thegerund always has the same function as a noun(although it looks like a verb), so it can be used:a. as the subject of the sentence:- Eating people is wrong. Hunting elephants isdangerous.- Flying makes me nervous.
b. as the complement of the verb to be:- One of his duties is attending meetings.- The hardest thing about learning English isunderstanding the gerund.- One of lifes pleasures is having breakfast inbed
c. after prepositions. The gerund must be usedwhen a verb comes after a preposition:- Can you sneeze without opening your mouth?- She is good at painting.- Theyre keen on windsurfing.- She avoided him by walking on the opposite sideof the road.- We arrived in Madrid after driving all night.- My father decided against postponing his trip toHungary.
This is also true of certain expressions endingin a preposition, e.g. in spite of, theres nopoint in..:- Theres no point in waiting.- In spite of missing the train, we arrived ontime time.
d. after a number of phrasal verbs whichare composed of a verb +preposition/adverbExample: to look forward to, to give up, to be for/against, to take to, to put off, to keep on:- I look forward to hearing from you soon. (at the end of a letter)- When are you going to give up smoking?- She always puts off going to the dentist.- He kept on asking for money.
NOTE:There are some phrasal verbs and otherexpressions that include the word to as apreposition, not as part of a to-infinitive:- to look forward to, to take to, to be accustomed to, tobe used to. It is important to recognise that to is apreposition in these cases, as it must be followed by agerund: - We are looking forward to seeing you. - I am used to waiting for buses. - She didnt really take to studying English.
e. in compound nouns Example: - a driving lesson, a swimming pool, bird- watching, train-spotting It is clear that the meaning is that of a noun, not of a continuous verb. Example: - the pool is not swimming, it is a pool for swimming in.
f. after the expressions:cant help, cant stand, its no use/good, and the adjective worth: - The elephant couldnt help falling in love with the mouse. - I cant stand being stuck in traffic jams. - Its no use/good trying to escape. - It might be worth phoning the station to check the time of the train.
GERUND OR INFINITIVE?The two groups of verbs below can be followed eitherby the gerund or by the infinitive.
