Writing the second half of a biography about Darwin and his theory of evolution

In a biography, we write using a formal tone in the third person; our writing is mostly, but not all, in the past tense. We use a range of cohesive devices to connect ideas together. We orally rehearse our sentences before we write, using our notes. We can include parenthesis to add extra details to a sentence, including using brackets and relative clauses. We give a title for the biography as a whole and subheadings for each paragraph. Each paragraph is indented.
