Infinitive form

Here is the form you're very often tempted to use instead of gerunds: the infinitive form.  

It is composed of the base verb preceded by TO, which indicates the infinitive form. 

Infinitive has its own uses that you must know...  

1) INFINITIVE is normally preceded by TO: 

- I asked him to tidy up his room before school.

- I want to have a tidy home every day. 

2) IN THE  NEGATIVE FORM,  be aware of the WORD ORDER:  NOT TO, NEVER TO.

- I hope not to be late! 

- She'd like him never to lie again!

3) TO + infinitive may also be translated as: 'à + infinitif'/ 'de+ infinitif' and express a purpose:

- It was easy to understand. 

4) After ENOUGH and TOO, it is translated by 'pour + infinitif ' and  expresses an AIM.  

- You're not old enough to go to a bar with your friends.

- I'm too hungry to refuse this piece of cake. 

5) Infinitive isn't used to give instructions : use IMPERATIVE. 

- Do not enter beyond this point. 

- Knock before entering!  

6) a) TO+ INFINITIVE expresses an aim, a purpose.

- The escaping burglars took the small roads to avoid the police.

   b) In a more formal style 'so as to// in order to' are used.

- I  moved to a new flat so as to be/ in order to be/ near my work.

* For negative sentences: SO AS NOT TO  and IN ORDER NOT TO (mind the word order).

- You should leave earlier so as not to be/ in order not to be late for her arrival.

There you are! I'm sure you'll pass the test easily and won't make the mistakes again!
