   For can express the function of something. It can also be equivalent to an "as-clause" or a "because-clause". Compare this section with section 11. See also unit 27, section 3.

21 Examples:
   Swimming is very good for the human body.
   It's very good for the human body to swim.
   It would be better for you to stay here.

   Formerly, it was common for an infinitive to be the subject of a sentence41. This is not very usual nowadays. Instead, we use a gerund or an introductory "it" plus an infinitive. All the same, the gerund is not possible when referring to a specific action, as in the last example above. Note also:
     It is vital to read.
     Reading is vital.
     It is vital reading

a  It would be a good thing (keep) watch for possible dangers.

22 Examples:

   It's pointless to try/trying to convince her. She will always do it her own way.

   I took the opportunity of riding/to ride a horse when I visited her ranch.
   When I was there, I had a lot of opportunities/I didn't have much opportunity of meeting/for meeting people/to meet people.
   You won't have another chance to talk/of talking to him.
(You will not have another opportunity.)
   We don't have much chance to watch the telly. (We do not have much opportunity (or time) to watch the telly; We don't have much chance of watching the telly is just possible, but the infinitive construction is much better.)
   You don't have much chance of getting another week off. There's a lot of work at the office, and you have had a month off already. (This is not very likely.)
   I broke my neck finishing/to finish this report for today, and now you say you don't need it.

   It's so good to talk/talking to you after such a long time.
   I can't bear45/stand46/endure to see/seeing people ill-treating animals.
   I intend/propose/purpose to climb/climbing the Alps next summer.
   It began/started to snow/snowing47.

   As seen above, after some verbs or expressions, it does not usually matter whether we use an infinitive or a gerund.

a  "Mr Johnson, this is my wife."
   "Nice (meet) you."
b  She began (get) off the point.
c  The government intends (abolish) capital punishment.
d  He can't endure (see) a woman weeping.

23 Examples:
   She likes cooking. (= She enjoys cooking.)

   She would like to go out tonight.
   He prefers studying/to study at night.
   He would prefer not to go to his wedding.
   I hate to tell you this, but I have to.
   I hate taking/to take exams.
   I'd hate not to be invited to your birthday party.
   They love humming/to hum Frank Sinatra's songs.
   She'd love to see that film.

   Like is normally followed by a gerund when it means "enjoy". After hate, love and prefer, we can have either a gerund or an infinitive, but the gerund is more usual in British English. When we use "would" or when we refer to a particular occasion, only the infinitive is possible.

a  "Would you like (come) to the opera with me tonight."
   "Oh, I'd love to, but I can't."
b  I like (take) one of these tablets every day. They make me feel better.

d  I hate (disturb) you now, but I have something important to tell you.
e  "If you want, I can go with you."
   "No, thanks. I prefer (go) alone."

24 Examples:
   I remember going for long walks along the shore when I was young. (Remember + a gerund refers to an action that occurred earlier.)
   Remember to phone him this afternoon. (= Do not forget to phone him this afternoon; that is, a later action.)
   I'll never forget48 visiting that man. (= I'll always remember visiting that man.)
   I forgot to tell him. (= I did not remember to tell him.)

e  I'm sorry (arrive) home so late last night, but I had a very important business meal.

28 Example:
   I am looking forward to hearing from you soon.

   When to is a preposition, it must be followed by a gerund. After a preposition, we can only use a gerund, a noun or a pronoun. So, we could also have said I am looking forward to my summer holidays.

y  I never (go) (climb). I'm afraid (fall).
z  He introduced himself to the audience and then went on (say) that he was going (build) a new hospital in the town.

35  Continuous passive infinitives have not been included here because they are unusual.
36  In this particular case, we could also have said We would have liked to go sightseeing or We would have liked to have gone sightseeing. This is also possible with the verbs hate, love and prefer.
37  Perfect infinitives refer to the past. See unit 22, section 17, footnote 21.
38  The perfect gerund after verbs which are already in a past form is not usually necessary, unless there is ambiguity if we do not use it:
     He admitted having wished to marry her. (= He admitted he had wished to marry her. When he admitted this, he probably did not want to marry her any longer.)
     He admitted wishing to marry her. (= He admitted he wished to marry her. He still wanted to marry her when he admitted this.)

   This may also be applied to present participles:
     Phoning her, he remembered that he had to ring his parents up. (While he was phoning her, he remembered that he had to ring his parents up.)
     Having phoned her, he remembered that he had to ring his parents up. (Once he had phoned her, he remembered that he had to ring his parents up, that is to say, first he phoned her and then he remembered that he had to ring his parents up.)
     Having seen her/Seeing her, he went to say hello to her. (Ambiguity cannot arise here, so both forms are possible.)
39  Note too:
     There are a lot of windows to clean/to be cleaned.
     There isn't anything to do here.
(We had better go somewhere else.)
     There isn't anything to be done. (We cannot do anything about it.)
40  Use the plain infinitive.
41  The following constructions are possible in modern English, but not very common:
     For the human body to swim is very good. (very formal)
     For you to stay here would be better. (very formal)
42  Note the following: It's worth reading Jane Eyre by Charlotte Brontë.
43  See section 26, footnote 52 in this unit.
44  Observe as well:
     "This is Mr Gibbs and this is Miss Lee."
     "(It's) nice to meet you, Miss Lee."
     "(It's) nice to meet you too, Mr Gibbs."
     Well, I have to go now. (It's been) nice meeting you./(It's) nice to have met you.
     "Mr Fowler, I'd like to introduce you to Mrs Scott."
     "(I'm) pleased to meet you."
     "(I'm) pleased to meet you, too."

45  Notice as well:
     What you have just done doesn't bear thinking about. (You have just done such a terrible thing that it is better not to think about it.)
46  Note the following: I can't bear/stand people ill-treating animals, rather than I can't stand people's ill-treating animals. See section 26, footnote 52.
47  After begin and start, both the infinitive and the gerund are possible. The infinitive being more usual for actions that cannot be controlled by us or are short; the gerund, for long voluntary actions. In the following cases, however, they take the infinitive:
     It's beginning/starting to clear up. (a continuous tense)
     She began/started to see things more clearly after I explain the whole affair to her. ("See" is a verb not used in continuous tenses. See unit 9, sections 5 and 6.)

   When begin and start are preceded by "to", we use a gerund after them:
     I'd like to begin/start taking German lessons next month.

   Cease and continue behave similarly:
     It ceased snowing/to snow.
     He continued dancing/to dance.

48  Especially in the negative.
49  Or I regret having got drunk last night.
50  Mainly before verbs of saying, such as "announce", "inform", "say", "tell".
51  Apart from the expression "I dread to think", dread is usually followed by a gerund:
     I dread to think what might happen if a nuclear war broke out.
     I dread having to die.

52  It is sometimes possible to use a personal object pronoun in place of a genitive or a possessive adjective before a gerund. This usage is quite common in informal English, and is sometimes preferred:
     I don't like his/him telling lies.
     I didn't mind your/you interfering.
     I remember your/you getting ill.
     I remember you looking after me when I was little.
(Rather than I remember your looking after me when I was little.)
     I didn't like my car being left unlocked. ("My car" is an inanimate object. Do not say "my car's".)
53  The infinitive is more usual than the gerund.
54  The infinitive is not possible here. In the example above, we cannot say The streets were so lonely that I was afraid that I might go out alone, unless we wish to imply that we lack willpower, in which case the infinitive would not be possible.

   Another instance: He was so angry with me that I was afraid to talk/of talking to him. The following sentence is not logical: He was so angry with me that I was afraid that I might talk to him. Therefore, we can make a golden rule: When we can use a that-structure, the construction of + a gerund is necessary:
     I didn't tell my parents the truth because I was afraid of being scolded.
     I didn't tell my parents the truth because I was afraid that I might be scolded.

55  Compare these sentences:
     My father agreed to lend me some money. (My father said that he would lend me some money.)
     My father agreed to my arriving home last night. (My father allowed me to arrive home late last night.)
56  In can be removed.
