We use demonstrative adjectives to point out specific people or things.
This and that modify singular nouns.
This is used to point out something that is near by:
"This book I'm holding is very old."
That is used to point out something that is farther away:
"That mountain looks small because it is so far away."
These and those are used for plural nouns.
These is similar to this, but it is used for nearby plurals:
"These keys are all the wrong size for this door."
Those is similar to that, but it is used for far away plurals:
"Those taxi drivers we had on holiday were dangerous drivers."
