If you want some further practice on formal writing, you can work with these sections from the workbook:
- Reading and Writing Portfolio 3: Holiday arrangements (pages 74-75).
- Reading and Writing Portfolio 9: A letter of application (pages 86-87).
- Reading and Writing Portfolio Plus 3: Asking for information (pages 98-99). Be careful with this one, as the register in the model is more informal because contractions are used.
