One and ones exercises
Practise substitute words “one” and “ones”.
Sometimes we use the word “one” when we don’t want to repeat the noun. For example: Would you like a sandwich? I’d like one. “One” replaces a singular countable noun. “Ones” replaces a plural noun. We can use one and ones with the demonstratives: this one, that one, these ones, those ones. We can also say “the one” and “a + adjective + one”. The online exercises on this page will help you practise substitute words “one” and “ones” in sentences. Recommended for beginners.
