Audience, Thesis, and Supporting Evidence

In August 1588 England feared invasion: a huge Spanish fleet, the Armada, had sailed up the English Channel, and a Spanish army waited across the sea in the Netherlands. Queen Elizabeth I rode out to her soldiers at Tilbury, near London. Many of them had never seen a woman lead an army, and she knew it. In the version of her speech that has come down to us, she said: "I know I have the body of a weak and feeble woman; but I have the heart and stomach of a king, and of a king of England too." She named her audience's doubt before they could, and turned it into a reason to trust her. Every choice in that sentence starts from what she believed her listeners were thinking.

Unit 1 established that a text has an audience. Unit 2 makes that audience the engine of every choice a writer makes.

• Writers' perceptions 看法 of an audience's values 价值观, beliefs 信念, needs, and background guide the choices they make. Note the word perceptions: what steers the writing is the writer's picture of the audience, which may be accurate or not.
• To achieve a purpose, writers make choices in an attempt to relate to an intended audience 目标受众's emotions and values.
• Arguments seek to persuade or motivate action through appeals 诉求 - the modes of persuasion 说服方式.

Worked example: the audience at Tilbury.

A scoring sentence: "By naming the soldiers' doubt about a woman commander before they can voice it, Elizabeth turns a weakness into proof of her honesty, so the claim to a king's heart that follows sounds earned rather than boastful."

The same three statements now become a writing instruction. Before drafting, decide:

• What does this audience already believe about the subject?
• What do they need - information, reassurance, a reason to act?
• What do they value, and which of those values can honestly be connected to my position?

Compare drafts for different audiences: which needs and values does each address? The same wording can sometimes serve overlapping audiences; similarity alone does not prove that no audience was considered.

Unit 2 deepens Unit 1's treatment of evidence with three claims about how evidence works:

• Writers use evidence strategically and purposefully to illustrate, clarify, set a mood, exemplify, associate, or amplify. Evidence does a job, and naming that job is analysis.
• Strategically selected evidence strengthens the validity 有效性 and reasoning of the argument, relates to an audience's emotions and values, and helps establish the writer's credibility 可信度.
• An effective argument contains sufficient evidence 充分的证据 - sufficient when its quantity and quality provide apt support for the line of reasoning.

That third point is often misread as "more is better". Sufficiency is quantity and quality together: relevant, reliable 可靠的 evidence with explained connections is more useful than a larger pile of loosely related material. No fixed count guarantees sufficiency.

Applying the above to your own writing, choose each piece of evidence for a stated reason. In practice this means being able to finish the sentence: I am using this piece because it ...

• ... illustrates a claim that would otherwise stay abstract;
• ... establishes my credibility on a subject where readers may doubt it;
• ... connects my position to a value the audience already holds.

Selecting evidence for a reason helps you plan commentary, but you must still explain how it supports the claim and acknowledge what it cannot establish.

• A thesis 论点 is the main, overarching 总体的 claim a writer seeks to defend or prove by using reasoning supported by evidence.
• A writer's thesis is not necessarily a single sentence or an explicit 明确的 statement, and may require a thorough reading to identify.

That second point matters for the reading side of the exam. On a rhetorical-analysis passage, the thesis may be distributed across the text or implied 隐含的 by its structure. Do not assume the first sentence of the second paragraph is the thesis because that is where you would put yours.

The writing objective is precise: write a thesis statement that requires proof or defence and that may preview the structure of the argument.

Two independent requirements sit in that sentence:

• It must require defence. Apply the Unit 1 test again: could a reasonable person disagree? A topic or uncontested observation alone may leave the position unstated; factual claims can themselves require evidence. State the position the task asks you to defend.
• It may preview the structure - optional, but useful, because a thesis that names the lines of reasoning it will pursue gives the essay its shape.

A defensible thesis responds to the actual task and states a position requiring support. Restating a prompt alone does not supply that position. A weak thesis does not by itself determine all other parts of an essay's assessment; do not claim a guaranteed total from one sentence.

Original practice source pack: an evening library trial

This prompt, evidence and letter are fictional teaching material, not an authentic AP question or real school survey. The task is to recommend whether a principal should try one evening library session each week for four weeks. The principal must consider access, staffing and cost.

Original model letter. “Please trial one evening library session a week for four weeks, subject to confirmed staffing and safe travel arrangements. In our practice survey, 18 of 30 volunteer respondents said they would attend; one explained that sharing a room makes quiet study difficult. Those responses suggest a reason to test access, not a guarantee of attendance. Record visits and costs during the trial before deciding whether to continue.”

Worked analysis. The letter connects a concrete need to access, acknowledges the principal's staffing concern, and uses survey results as a reason for a limited test rather than permanent opening. The respondent's situation illustrates the need; the numbers describe this sample; the qualification 限定 limits the conclusion. Transparent limits can support credibility, but do not prove that the principal will be persuaded.

Practice. Revise the recommendation for students who want a quiet study space. Then state one reason the principal might still decline. Keep the underlying evidence and its limits honest.

Thesis comparison. “There are arguments for and against opening the library” names a topic without deciding. “The school should test one evening session for four weeks, because the responses suggest an access need while uncertain attendance and costs make permanent opening premature” states a specific, arguable position and previews its reasoning. It still needs support.

Answer each before reading the model answers below.

1. A writer arguing for longer school holidays addresses parents who both work. What need of this audience must the argument meet?
2. Is this thesis defensible? "Many students use phones." Explain.
3. Write a defensible thesis about school start times.
4. A writer addresses an audience that strongly disagrees. Should the thesis come first or later? Explain.
5. A student says: "A thesis is just the topic of my essay." Correct the student.

1. Childcare: an argument for longer holidays must answer who will look after the children, or these parents will reject it.
2. No. It is a fact nobody disputes, so there is nothing to argue.
3. For example: "Secondary schools should start at 9:00 rather than 7:30, because teenagers' sleep patterns make early lessons the least productive of the day."
4. Often later: a hostile 敌对的 audience may stop listening after a direct claim, so writers first build common ground 共同点 with shared values or facts.
5. A topic names a subject ("school start times"); a thesis takes a defensible 可辩护的 position on it, one a reasonable reader could dispute.

• Consider the audience’s needs and values alongside purpose, context and evidence. Similar wording may serve overlapping audiences.
• Name what evidence does - illustrate, clarify, associate, amplify. That is analysis; listing evidence is not.
• Sufficiency is quantity and quality, not volume. Explain relevance and reliability; no fixed number guarantees enough support.
• A thesis in a passage may be implied or distributed. Read the whole text before deciding.
• Your own thesis must be arguable. Restating the prompt alone leaves the position unstated; it does not determine the whole essay’s assessment.
• Previewing your line of reasoning in the thesis is optional but makes the rest of the essay easier to organise.
