Author'S Purpose, Audience, and Organization
Effective writing begins with three decisions: why the piece is being written (purpose), who will read it (audience), and under what circumstances it will be read (occasion). Together with the specific task (a letter, a report, a speech, a set of directions), these decisions determine the content a writer includes, the format the writer chooses, and the register, or level of formality, the writer uses. Exam questions in this area typically present a writing situation and ask which sentence, revision, or format is most appropriate for it.
Register: Formal and Informal Language
Register is the variety of language a writer selects for a situation. Formal register is used for academic, professional, and public writing: complete sentences, precise vocabulary, third person or a restrained first person, no slang, no contractions in the most formal documents, and an objective tone. Informal register is used with friends, family, and familiar audiences: contractions, conversational phrasing, first and second person, and a relaxed tone. Neither register is incorrect in itself; an error occurs when the register does not match the audience and occasion.
Contractions Avoided in formal documents
Person Third person or restrained first
Sentence style Complete, varied, carefully structured
Typical tasks Reports, essays, business letters, speeches
Formal writing is not the same as wordy or inflated writing. A sentence such as “It is the considered opinion of the undersigned that the aforementioned meeting ought to be postponed” is formal but ineffective. The clearer formal version is “I
recommend postponing the meeting.”
Audience shapes content: a reader who knows little about a topic needs definitions and background, while an expert reader needs specifics and can do without basic explanation. Purpose shapes format: steps in a process call for a numbered list, a comparison calls for a chart or parallel paragraphs, a request to an official calls for a business letter with a clear statement of the request near the beginning, and a persuasive appeal to a community calls for a letter to the editor or a speech. A writer should include only the information the intended reader needs to understand or act on the message.
Worked example: one message, two audiences. A class field trip to a state park has been moved from Thursday to Friday because of a forecast of heavy rain. The facts are identical in both versions below; the register, the details selected, and the format change with the audience.
To families (formal notice)
Dear Families: Because heavy rain is forecast for Thursday, the fifth-grade field trip to the state park has been rescheduled for Friday. Students should arrive at the usual time and bring a packed lunch and a signed permission form. Please contact the front office with any questions.
To classmates (informal message)
Heads up: the park trip moved to Friday because of the rain on Thursday. Same time as always. Don't forget your lunch and the permission slip!
The family notice uses a salutation, complete sentences, and a polite closing that tells readers what to do next. It includes the grade level and the instruction to contact the office because a family audience needs that information. The classmate message uses contractions, an interjection, and an exclamation, and it omits details the classmates already know.
When a question asks for the sentence that is most appropriate for a given audience, first identify the register the situation demands, then eliminate options that are too casual (slang, contractions in a formal letter) or too technical for the reader. The best answer also delivers the information the reader actually needs.
Expository and argumentative writing is organized as a hierarchy. The thesis statement expresses the controlling idea of the entire piece. Each body paragraph develops one part of that idea and is governed by a topic sentence. Each topic sentence is developed with supporting details. Questions on this objective ask candidates to identify a thesis, choose the strongest thesis or topic sentence, and judge whether details adequately support a claim.
A detail that does not support its topic sentence weakens the unity of the paragraph.
Strong and Weak Thesis Statements
A strong thesis is specific, arguable or focused (it states a position or a clear angle rather than a bare fact), and manageable within the length of the piece. It often previews the main points. A weak thesis is a simple fact, an announcement of the topic, a question, or a statement too broad to develop.
This essay is about school Announces the topic only gardens.
School gardens improve students' science learning, nutrition, and cooperation.
Recycling is a process. Bare fact; nothing to develop
A curbside recycling program would reduce our town's landfill costs and litter.
Sports are good. Vague and too broad
Team sports teach middle school students to set goals and resolve conflicts.
Should homework be banned? A question, not a claim
Homework in the primary grades should be limited to short daily reading.
Paragraph Structure and Kinds of Support
A well-built body paragraph contains a topic sentence stating the paragraph's main idea, several supporting sentences that develop it, and often a concluding or transitional sentence that ties the paragraph back to the thesis or leads to the next point. The topic sentence is usually first, but it may appear at the end of a paragraph that builds to its point, or it may be implied in narrative writing.
Facts and statistics: verifiable information from a credible source. Examples and illustrations: specific instances that make a general statement concrete. Reasons: explanations of why a claim is true, used heavily in argument. Expert testimony or quotations: the words of an authority, cited accurately.
Anecdotes: brief accounts of an event that illustrate the point.
Sensory and descriptive details: used mainly in narrative and descriptive writing.
Worked example. Topic sentence: “The town library has become a center of community life.” Relevant support: the library now hosts weekly tutoring for students; local clubs reserve its meeting rooms; a summer reading program draws families from every neighborhood. Irrelevant detail: “The library building was painted gray.” The color of the building does not show that the library is a community center, so it should be deleted.
To choose the best topic sentence for a paragraph, read all the supporting sentences first and ask what single idea they share. The correct option is broad enough to cover every detail but narrow enough to exclude ideas the
