Reading and listening to whole books, not simply extracts, helps you to increase your vocabulary and grammatical knowledge, including your knowledge of the vocabulary and grammar of Standard English. These activities also help you to understand how different types of writing, including narratives, are structured. All these can be drawn on for your writing.
You should understand, through being shown, the skills and processes essential to writing: that is, thinking aloud as you collect ideas, drafting, and re-reading to check the meaning is clear
Drama and role-play can help improve your writing by providing opportunities for you to develop and order your ideas by playing roles and improvising scenes in various settings.
You might draw on and use new vocabulary from your reading, your discussions about it (one-to-one and as a whole class) and from your wider experiences.
