Tell Ss how to pronounce them correctly and then ask Ss to repeat two times. - Read the words once for Ss to hear then ask Ss to read in chorus a few times. - Let Ss practice reading these words individually. - Call some to read aloud to check. Practising sentences containing the target sounds: - Ask Ss to work in pairs and read aloud the given sentences. - Go around to listen and take notes of the typical errors. - Call some to read the sentences to check. II. Grammar: 1. Review of relative clauses: - Give some sentences using relative pronouns and then direct Ss how to omit these pronouns. Examples: 1. The man who lives next door is a doctor. 2.
