When one verb is followed by another, the second verb is not always in the infinitive. You can say I want to travel but not I enjoy to travel. Enjoy is usually followed by the gerund, and so are quite a number of other verbs. The most common are:
admit appreciate avoid delay deny dislike dread (=dread to think) enjoy escape excuse feel like finish forgive give up hate imagine involve keep (on) like love mind (=object) miss pardon postpone practice prevent prefer put off recollect remember (=recollect) resent resist risk stop (=cease) suggest understand
The gerund is also used after the expressions: can’t help can’t stand to burst out crying/laughing it is no use/good it is useless to spend/waste time/money to be worth to be busy
Examples of verb + gerund sentences:
He admitted taking the money. Avoid over-eating. She dreads getting old. He escaped being eaten by wolves. Putting in a new window involve cutting away part of the roof. He kept complaining. I can’t understand his/him leaving his wife. (See 111) Is there anything worth buying? He was busy packing his things. It’s no good/use arguing.
Note that:
1. Some verbs (e.g. admit, deny, imagine, understand) can also take that-clauses.
2. Some verbs (e.g. remember, stop and others) can be followed by the infinitive with the difference in the meaning.
A. If the verb or verb plus preposition is followed directly by the gerund, the gerund refers to the subject of the verb: Tom insisted on reading the letter. (Tom read it.)
But if we put a possessive adjective or pronoun before the gerund, the gerund refers to the person denoted by the possessive adjective/pronoun: He insisted on my/me reading it. (I had to read it.)
B. The most common verbs and expressions which can take either construction are:
dislike dread fancy involve like (negative) mind propose recollect remember resent save stop suggest understand approve of disapprove of insist on it’s no good/use there’s no point in what’s the point of
He doesn’t like working late.
He doesn’t like me/my working late.
I object to paying twice for the same thing. I object to his/him making private calls on this phone.
C. Excuse, forgive, pardonand prevent are not followed directly by the gerund but take either possessive adjective/pronoun + gerund or pronoun + preposition + gerund: Forgive my/me ringing you up so early. Forgive me for ringing you up so early. You can’t prevent his/him spending his own money. You can’t prevent him from spending his own money.
appreciate usually requires a possessive adjective or passive gerund: I appreciate your giving me so much of your time. I appreciate being given this opportunity.
D. In formal English the possessive adjective is used with the gerund. But in informal English we very often use the pronoun. So, there is a choice of forms but it is recommended to use the pronoun.
In very formal English the possessive case is used: We are quite used to William’s grumbling. But it is much more usual to omit the ‘s: We are quite used to William grumbling. However, the genitive can be used in cases when the gerund is the subject of the sentence: I am sure William’s sitting up so late is bad for his health.
