Final answer:
Standard English is typically required in professional and academic settings to demonstrate education and professionalism, although informal settings often allow for more natural language variations. The choice to use standard or nonstandard English should align with the expectations of the rhetorical situation, including the audience and purpose of the communication.
Step-by-step explanation:
When considering which writing situations require the use of standard English, it is paramount to recognize its importance in various professional and academic settings. For instance, academic writing, formal business correspondence, and professional publications typically expect the writer to employ a standard variety of English that adheres to grammatical norms and formal style guidelines. In such contexts, language serves not only as a means of communication but also as a marker of education and professionalism. Therefore, when writing a lab report, a research paper, or a resume, the use of standard English is necessary to meet the expectations of the academic or professional audience. Furthermore, in maintaining a consistent use of language, it is essential to be mindful of the rhetorical situation, which includes the purpose, audience, and context of the communication.
On the other hand, informal settings may not compel the use of standard English. For example, conversing on social media, texting friends, or participating in community dialogues often allow for more natural and regional linguistic variations. However, when crafting a profile or personal narrative for a class assignment, or when engaging with an audience that values standard English, it is crucial to match the language used to their expectations. In doing so, one may utilize a language variety that conveys authority and knowledge, demonstrating proficiency in both the subject matter and the language itself.
It is crucial to note that variations of English among communities, including regional dialects and language influenced by cultural backgrounds, offer valuable identities and should be respected. While standard English is preferred in certain writing scenarios, it is by no means the only acceptable form of communication, and the choice of language should align with the specific rhetorical situation faced by the writer.
