Relative clauses – Part One
Relative clauses provide additional information about a subject or object in a sentence.
A relative clause usually comes directly after the subject or object it refers to.
This is the man who stole my cat. - subject
He stole the cat that I bought last week. - object
Relative clauses usually begin with a relative pronoun or adverb.
|Relative Pronoun||Relative Adverb|
The number of cars.
The number of cars that were sold in June.
This relative clause defines (or distinguishes) the exact type of car sales the writer is referring to. So, the writer is not talking about all cars sold, only those sold in June. For this reason this is a defining relative clause.
The questions provided with IELTS diagrams often contain a noun that can be changed into a verb to help paraphrase (see here). This is usually easiest when combined with a quantifier and relative clause.
