Infinitive of purpose

For + a noun or object pronoun often precedes the infinitive as its subject.

Not is used before the infinitive to form the negative

Infinitive or -ing form?

Verb + to-infinitive

We usually use to-infinitive after verbs which express plans, decisions, expectations and commitments (ideas about actions which follow).

Arrange, forget, learn, plan, ask, help, manage, promise, decide, hope, offer, refuse, expect, intend, prepare, want

E.g.: He asked to leave the class early. We are learning to use a new program. My brother promised to help me with my homework.

Other verbs which take to-infinitive are those connected with the idea of making people think something: pretend, appear and seem.



Verb + -ing form (gerund)

We use an -ing form after some common verbs:

Avoid, feel, like, mind*, risk, delay, give up, miss, spend time / money, dislike, practice, suggest, enjoy, keep, put off, understand

E.g. Please avoid arriving late for class tomorrow. My tutor suggested revising for the exam. How much time do you spend watching TV every day?

(*) We use mind in questions and negative sentences.

E.g.: Did he mind lending you his notes? I don't mind being alone when I'm busy.

Exercise 1 Put the verb in the right form: -ing or infinitive (with or without to).

1 She doesn't allow smoking in the house, (smoke)

2 I've never been to Iceland but I'd like _____ there (go)

3 I'm in a difficult position. What do you advise me _____ ? (do)

4 She said the letter was personal and wouldn't let me ______ it. (read)

5 We were kept at the police station for two hours and then we were allowed _______ (go)

6 Where would you recommend me ______ for my holidays? (go)

7 I wouldn't recommend _______ in that restaurant. The food is awful, (eat)

8 The film was very sad. It made me ______ (cry)

9 Carol's parents always encouraged her _______ hard at school, (study)

 

Present Perfect

When we use the present perfect there is always a connection with now. The action in the past has a result now:

E.g.: 'Where's your key?' 'I don't know. I've lost it.' (I haven't got it now)

We often use the present perfect to give new information or to announce a recent happening:

E.g.: Ow! I've cut my finger.

You can use the present perfect with just, already and yet: Just = 'a short time ago':

E.g.: 'Would you like something to eat?' 'No, thanks. I've just had lunch.'

We use already to say that something happened sooner than expected

E.g.: 'Don't forget to post the letter, will you?' 'I've already posted it.'

'What time is Mark leaving?' 'He's already gone.'

Yet = 'until now' and shows that the speaker is expecting something to happen. Use yet only in questions and negative sentences (see also Unit 110C):

E.g.: Has it stopped raining yet?

E.g.: I've written the letter but I haven't posted it yet.
