23.                                 Verb + Preposition. Patterns

When we use a preposition, we can follow it with the gerund:

{­verb phrase} + {­preposition} + {­gerund}

With most prepositions this is no problem. However, when we use the preposition to, students often confuse it with the to + infinitive structure.

In the first example, work is a noun and to a preposition; in the second example, work is a verb.

If you do not know whether to is with the infinitive or gerund, try putting a noun after it:

This is acceptable so to is a preposition and must be followed by the gerund.

In the following case, to is not a preposition so we do not follow it with the gerund:

 

We use different patterns when we join two verbs. These are some of the more common patterns:

1) {­verb + {­to} + {­infinitive}

Verbs include: afford, agree, appear, arrange, ask, attempt, be, bear, beg, begin, care, choose, consent, dare, decide, determine, expect, fail, forget, happen, hate, have, help, hesitate, hope, intend, learn, like, love, manage, mean, need, neglect, offer, ought, plan, prefer, prepare, pretend, promise, propose, refuse, regret, remember, seem, start, swear, threaten, trouble, try, used, want, wish.

2) {­verb} + [object] + {­to} + {­infinitive}

Verbs include: advise, allow, ask, bear, beg, cause, command, compel, encourage, expect, forbid, force, get, hate, help, instruct, intend, invite, leave, like, mean, need, oblige, order, permit, persuade, prefer, press, promise, recommend, request, remind, teach, tell, tempt, trouble, want, warn, wish.

3) {­verb} + [object] + {­infinitive}

In the passive, we use the to + infinitive pattern:

In this group we include most (but not all) of the modal auxiliary verbs and verbs of senses. Verbs include: could, feel, hear, help, let, make, may, might, must, notice, see, shall, should, watch, will, would.

 4) {­verb} + {­gerund}

 

5) Some verbs can take either the gerund or the infinitive. There is very little difference between these two:

I like skiing.

I like to ski.

In general, the gerund refers to a general activity while the infinitive refers to a specific case.

There are some important exceptions though:

Remember to visit my mother.

Remember visiting my mother.

In this case, the gerund refers to what happened before the main verb and the infinitive what happened after the main verb.

Remember visiting my mother = you visited her in the past and now I am asking you to remember it.

Remember to visit my mother = you must remember now that you will visit my mother in a while.

Verbs in this category include: advise, allow, attempt, begin, can't bear, continue, forbid, forget, go on, hate, hear, intend, like, love, permit, prefer, propose, regret, remember, see, start, stop, try, watch.
