What I had learnt in the English lessons in the last week(from 19-11-2007 to 23-11-2007)(26-11-2007)

I had learnt the grammar of 'to'infinitives' and 'bare infinitive'.
To-infinitives can be followed by objects of other words. It called infinitive phrases.
We can use a to-infinitive to say why someone does something.
We can also use a to-infinitive to say why someone needs or uses something.
The bare infinitive is the infintive form without the word to. Bare infinitives, like to-infinitives have no tense or singular/plural ending. You do not change them at all. After the verbs let and make you can use a verb+indirect object+bare infinitive pattern.
