The demonstratives
When talk us about of objects usually used forms to referred according how many, where are they, here used us the principals:
THIS: is to objects that are near and singular.
THAT: to objects that are fair and singular.
THESE: is to objects that are near and plural and THOSE to the objects.
The form to use these demonstratives in affirmative sentences are:
This ¬+ are + my + glasses
(Demos) + (to be) + (subj) + (complement)
In the negative sentences are:
That + isn’t ¬+ my pen
(Demos) + (to be -) + (subject) + (complement)
The question sentences are:
Is this pen mine?
Are those desk in the classroom?
(To be) + (Demos) + (object) + (complement)
The demonstratives are the most important because can we used to for many prayers or to indicate in a place the objects that are there and be able to talk about them.
