Talk about “What is your favourite colour?” 2. Show a picture of a yellow coat and say, “The rulers in ancient Chinaliked wearing yellow.” Show the sentences and lead in the object clauses. We know that it is a yellow coat. I hear that the rulers in ancientChina like to wear yellow. Step 2 Grammar A 1. Give them some explanations about object clausesintroduced by that. T:An object clause functions as the object of a sentence. We use that to introduce an object clause that is a statement.
