Activity 1: Warm-up · 5 minutes
Who or Which?
a) Aims
Ss recall how to describe people and things using relative pronouns, and get ready for the lesson focus on defining relative clauses.
b) Content
T writes two incomplete sentences on the board: 'A teacher ___ teaches English is kind.' and 'A book ___ is on the desk is new.' Ss choose who or which for each gap and say why. T then asks: 'Do we use a comma before the relative clause in these sentences?'
c) Expected outcomes
Ss answer: 'A teacher who teaches English is kind.' (who refers to a person and is the subject of teaches) and 'A book which is on the desk is new.' (which refers to a thing and is the subject of is). Ss note that the clauses identify a specific teacher and a specific book, with no commas. Ss write the title 'Defining relative clauses' in their notebooks.

Step 3: Report and discussion
T asks: 'Why who here? Why which here? Is there a comma before who or which?' T calls on two volunteers.
Students
Ss answer: 'Who is for people, and which is for things.' 'No, there is no comma, because the clause tells us which teacher and which book we mean.'

Step 4: Conclusion and assessment
T praises correct answers and writes on the board: 'who / that = people, which / that = things; no commas in a defining clause.' T announces the lesson topic: defining relative clauses.
Students
