THIS, THAT, THESE, THOSE
DEMONSTRATIVES are used to point out or identify a particular item, as follows:
THIS - Indicates something located close to the speaker
THAT - Indicates something located at a distance from the speaker
THESE - Indicates several things located close to the speaker
THOSE - Indicates several things located at a distance from the speaker.
NOTE: The location of the speaker, not the listener, is important here. It is sometimes possible to cause confusion if the listener is unable to see which object is being referred to. In which case a further clarification will be required, such as "over there", "on the counter", or "the blue one".
EXAMPLES:
JANET (Pointing to a object held in her other hand): "What is this?"
JOHN (Standing across the other side of the room): "That is a pencil."
JANET (Pointing at the window to an object in the garden outside): "What is that?"
JOHN (Looking through the window towards the object indicated): "That is a tree."
Remember that DEMONSTRATIVES are used in reference to the speaker. [What is near to one person may not be near the other]
JANET: "What's that you're holding?"
JOHN: "This is an egg. Here, catch!"
JANET: "Oops!"
JOHN: "That's a mess!
JANET holds up a garish pair of shorts. "What are these?"
JOHN replies, "Those are my shorts."
Make certain that you use "this" or "that" with SINGULAR and NON-COUNT NOUNS and "these" or "those" with COUNT NOUNS -
NON-COUNT COUNT
THIS orange is sweet. THESE oranges are bitter.
THAT truck is full. THOSE trucks are empty.
THIS milk is sour. THAT milk is fine.
Sometimes DEMONSTRATIVES can be used as PRONOUNS (referring to a particular NOUN.)
"Give me that!" (= Give me that book.)
"Whose are these?" (= Whose are these dirty socks?)
"This" and "that" can also be used with "one". "These" and "those" are more commonly used on their own.
"I want this one, not this one."
"I want these, not those."
"May I have that one, please?"
"May I have those instead, please?"
"This" and "that" are used differently by the British and Americans when Identifying callers on the telephone:
