Final answer:
No specific sentences using 'want', 'would like (to)', or 'would rather ('d rather)' were provided in the excerpts. The instructions mainly discuss proper email composition and proofreading techniques.
Step-by-step explanation:
From the provided excerpts, there do not appear to be any sentences that explicitly use the phrases want, would like (to), or would rather ('d rather). However, it is clear from the context that the focus of these excerpts is on the proper construction and proofreading of emails. To be more specific, sentences discussing wanting the email to be well-received, or ensuring the correct spelling and grammar, indirectly refer to the writer's desires or preferences when composing an email, which could be associated with the concept of want. To address the student's question directly, one would need the full content of Ben's email to identify specific sentences containing these expressions.
