This, That, These, Those
Demonstratives are used to point out a particular item. They are as follows:
This (indicates something close to the speaker)
That (indicates something away from the speaker)
These (indicates some things close to the speaker)
Those (indicates some things away from the speaker)
A: What is this? (pointing to something held in the speaker's hand or near the speaker)
B: A pencil.
A: What is that? (pointing to something at a distance from the speaker)
B: A tree.
Remember that demonstratives are used in reference to the speaker. (What is near "you" may not be near "me" and vice versa.)
A: What's that you're holding?
B: This is an egg. Here, catch!
B: That's a mess.
A: What are these (holding up a pair of slippers)
B: Those are slippers.
Be sure to use this/that with singular and non-count nouns and these/those with count nouns.
Sometimes demonstratives can be used as pronouns (to refer to a particular noun.)
This and that can also be used with one. However, these and those are more commonly used alone.
On the telephone, this and that are used differently in British and American English to identify callers.
