This document discusses using the words "one" and "ones" as substitutes for nouns to avoid repetition. It provides examples of how "one" can replace a singular countable noun and "ones" can replace a plural countable noun. It also explains that "one" and "ones" can be used with demonstratives like "this" and "that" as well as with the definite article "the". The document provides examples of these uses.

1. SUBSTITUTE WORDS ONE AND ONES

2. Sometimes when we don't want to repeat a noun, we
can replace it with one or ones.
Examples
Would you like a sandwich? Yes, I'd like one. (= Yes, I'd like a sandwich.)
Is there a cashpoint near here? Yes, there's one around the corner. (= Yes, there's
a cashpoint round the corner.)
"One" replaces a countable noun in the singular, and "ones" replaces a countable
noun in the plural.

3. this/that + one,
these/those + ones
the + one, the + ones a/an + adjective + one,
some + adjective + ones
We can use one and ones
with the demonstratives —
this, these, that, those.
One and ones can replace a
noun with the definite
article "the". We keep the
article in this case.
Examples
• Which cupcake would
you like to have? This
one or that one? (= this
cake or that cake)
• I don't know which
headphones to buy,
these ones or those
ones. (= these
headphones or those
headphones)
Examples
• — Are you talking about
your old job?
— No, I'm talking about the
new one. (= the new job)
• — Which sneakers are
yours?
— The ones with red
shoelaces. (the sneakers)
Examples:
• A nice car → a nice one
(countable singular)
• Some interesting articles
→ some interesting ones
(countable plural)
