1The skeleton: intro → body → conclusion

Every academic essay is the same three-part machine. Only the filling changes.

Part 1

Introduction

Hook, context, and the thesis. Names the question and answers it. Roughly 10–12% of the essay.

→
Part 2

Body

One paragraph per reason. Each one proves a different part of the thesis with evidence and analysis. Roughly 75–80%.

→
Part 3

Conclusion

Restates the claim in new words and says why it matters. Adds no new evidence. Roughly 10%.

Introduction
Hook the reader, give just enough context for the question to make sense, then state the thesis — one sentence that takes a position and previews your reasons. Do not summarise the whole text here; save that for the body.
1 paragraph
3–5 sentences
~10–12% of words
Body paragraph
One idea only. It opens with a topic sentence that is a claim, supplies evidence, explains how the evidence proves the claim (at least two sentences of commentary), then links back to the thesis. If a paragraph has two ideas, split it.
3–4 paragraphs
6–9 sentences each
~75–80% of words
Conclusion
Re-state the thesis in fresh words (never copy it), pull the reasons together into one idea, and close with a "so what" — the larger implication. No new evidence, no new argument.
1 paragraph
3–4 sentences
~10% of words
Common mistake
An essay that is all introduction and no body, or a conclusion that simply repeats the introduction word for word. Both signal "I ran out of ideas", not "I am finished".
Fix: count sentences per part before you submit
中文要点(核心)
  • 一篇文章只有三个部件:引言(钩子+背景+论点)、主体(每段一个理由+证据+分析)、结论(换话重述+升华)。
  • 字数比例很固定:引言和结论各约 10%,主体占 75–80%。不要把大量字数花在开头铺垫上。
  • 每段只说一件事,且每段都要等于论点的一个支架;与论点无关的段落直接删。

2Paragraph templates for four essay types

Same skeleton, different job. Tap a type to open its paragraph-by-paragraph plan (what each paragraph does → a sentence frame → an example).

a. Argumentative / Persuasive · you argue a position

The prompt asks whether something should or should not be true, or which side is stronger. Your job is to take a side and defend it — including a fair answer to the other side.

¶1Introduction

Gets attention, frames the debate in one or two sentences, and ends on a thesis that names your claim and your reasons.
Frame
Hook (question / striking fact). Context: "For years, ____ has been debated because ____." Thesis: "Although ____, ____ should ____ because ____, ____, and ____."
Example

In many districts the first bell rings before 7:30 a.m., forcing teenagers onto buses in the dark. Although later start times complicate bus schedules, high schools should begin after 8:30 a.m. because adolescent sleep cycles shift later, early starts depress attendance, and groggy students learn less.

¶2Body 1 — your strongest reason

States the first reason as a claim, proves it with the hardest evidence you have, and explains the link.
Frame
"The strongest reason to ____ is ____. According to ____, ____. This matters because ____."
Example

The strongest reason to delay the first bell is biology: studies of adolescent circadian rhythms show that melatonin release shifts roughly two hours later after puberty. According to the American Academy of Pediatrics, teenagers who start school before 8:30 a.m. accumulate a sleep debt that no weekend can repay.

¶3Body 2 — second reason, different evidence type

Adds a second, independent reason and deliberately uses a different kind of support (a statistic, a case study, an expert) so the essay does not rest on one source.
Frame
"A second consideration is ____. Consider ____. That pattern suggests ____."
Example

A second consideration is attendance. Consider the Fairfax County schools that shifted to 8:10 a.m.: within two years, chronic absenteeism among ninth graders fell by nearly a fifth, even though the curriculum never changed.

¶4Counterargument — concede, then answer

Names the strongest objection honestly, grants whatever part of it is true, then explains why your claim still stands. This paragraph is what separates a 4 from a 6.
Frame
"Critics rightly point out that ____. That concern is real, but it is not decisive: ____. Once ____ is accounted for, ____."
Example

Critics rightly point out that a later bell would collide with elementary bus routes and after-school jobs. That concern is real, but it is not decisive: districts from Seattle to Denver have staggered their routes without cutting services, and the attendance gains outweigh the added scheduling cost.

¶5Body 3 — third reason or synthesis

Either adds a third reason or shows how the first two combine into a bigger point. Keep it, drop it, or expand it — but never leave a reason that the thesis promised unwritten.
Frame
"Beyond ____, ____. Taken together, ____ and ____ point to ____."
Example

Beyond health and attendance, there is the classroom itself: a rested first-period class argues more, writes more, and gives up less easily, which is exactly the behaviour schools say they want.

¶6Conclusion

Restates the thesis in new words, compresses the reasons into one idea, and closes on the implication.
Frame
"____ is not a scheduling detail; it is ____. If schools ____, then ____."
Example

A start time is not a logistical footnote; it is a decision about what schools actually value. If a district will not move the bell by thirty minutes, it should stop pretending that student health is its first priority.

b. Rhetorical Analysis · you explain how a text persuades

The prompt hands you a speech, essay, or letter and asks how the author convinces the audience. You do not agree or disagree with the author — you explain the machinery (ethos, pathos, logos, diction, syntax, imagery, structure).

¶1Introduction

Names author, title, occasion, and audience in one or two sentences, then states a thesis that names two or three strategies and the effect each produces.
Frame
"In ____ (year), ____ addressed ____ in order to ____. By ____, ____, and ____, the author ____."
Example

In her 1851 speech in Akron, Sojourner Truth addresses a hostile convention in order to redefine who counts as a woman. By turning the audience's own religious language against its assumptions, by repeating a plain rhetorical question, and by reasoning from lived evidence, she reframes the debate as one about truth rather than tenderness.

¶2Body 1 — strategy one

Names the device, quotes a short phrase as proof, and then spends most of the paragraph explaining the effect on the audience. The quote is evidence, never the whole paragraph.
Frame
"The author first appeals to ____. When she writes '____', she ____. This choice presses the audience to ____."
Example

The author first appeals to ethos by borrowing the audience's own moral vocabulary. When she asks whether she is "not a woman," she forces the listeners to test their definition against a person standing in front of them, so that denying her womanhood now requires denying their own stated beliefs.

¶3Body 2 — strategy two

Names a second device that works differently (pathos or logic), quotes it, and analyses how it moves the audience rather than restating the first paragraph.
Frame
"The argument then shifts to ____. The phrase '____' does emotional work: ____. Because the audience already ____, this lands as ____."
Example

The argument then shifts to logos, reasoning from the plain facts of her own body and labour. Her catalogue of agricultural work is not self-pity; it is an audit, and it leaves the convention with no counter-example to answer.

¶4Body 3 — strategy three, or how the parts build

Either introduces a third strategy or shows how the first two depend on each other to reach the author's purpose.
Frame
"Finally, the author's ____ reinforces this. The repetition of '____' functions as ____, and together the strategies ____."
Example

Finally, the repeated question "Ar'n't I a woman?" works as a refrain: each repetition raises the cost of the audience's silence, until refusing her claim means refusing the meeting's own stated values out loud.

¶5Conclusion

States the overall effect of the strategies and why the text still matters. No new device, no new quote.
Frame
"Taken together, these choices ____. What the audience hears is not ____ but ____; that is why ____."
Example

Taken together, these choices convert a hostile room's assumptions into her own argument. What the audience hears is not a plea for protection but a demand for recognition, which is why the speech is quoted whenever a group is told it does not count.

c. Literary Analysis · you interpret a text

The prompt asks what a story, poem, or play means and how you know. The cardinal rule: no plot summary for its own sake. Every detail you mention must be doing interpretive work. Write about literature in the present tense.

¶1Introduction

Names title and author, and states an interpretive claim — not "this story is about loss" but "this story argues that loss is ____, shown through ____".
Frame
"In ____, ____ uses ____ to argue that ____. Through ____ and ____, the text ____."
Example

In "The Tell-Tale Heart," Poe uses the narrator's defensive voice to argue that guilt speaks loudest when it insists on its own innocence. Through the narrator's insistence on his sanity and his fixation on a pale blue eye, the story turns a murder into a study of self-deception.

¶2Body 1 — one element, one claim

Makes a claim about a single literary element (character, symbol, structure, tone), gives a short quotation or detail as evidence, and interprets it in the text's terms.
Frame
"The narrator's ____ reveals ____. When he says '____', the phrasing ____, which suggests that ____."
Example

The narrator's self-serving memory reveals how easily guilt rewrites itself as fate. He insists that "pride is a wonderful, terrible thing," a sentence that admits his motive and excuses it in the same breath, so the reader sees the confession and the cover-up at once.

¶3Body 2 — second element, building on the first

Examines a different element that strengthens or complicates the first, again quoting and interpreting rather than retelling.
Frame
"The story's use of ____ deepens this. The image of '____' echoes ____, and because ____, it ____."
Example

The story's imagery deepens the pattern. The ibis, red and out of place after the storm, echoes Doodle's red body and his refusal to fit a normal shape; when the bird falls, the text has already taught us how to read the boy's fate.

¶4Body 3 (optional) — a counter-reading, answered

Names the reading a careful classmate might offer, then shows why your reading accounts for more of the text. Use it when the prompt rewards nuance.
Frame
"It could be argued that ____. Yet ____, and only ____ explains why ____."
Example

It could be argued that the story simply mourns a lost child. Yet the narrator's adult voice returns on the last page to blame himself, not the storm, and only the pride reading explains why the final image is a memory rather than an accident.

¶5Conclusion

Names the theme in one sentence, reads one detail in that light, and steps back to the larger idea. Do not introduce a new symbol here.
Frame
"____ is therefore less about ____ than about ____. Read this way, the closing scene ____."
Example

The story is therefore less about a brother's accident than about the stories we tell to survive one. Read this way, the closing scene is not grief but evidence — the moment the narrator finally tells the truth about his own pride.

d. Research / Synthesis · you build one argument from several sources

The prompt gives you two or more sources and asks you to take a position that uses them. Quoting is not the point: the point is showing how the sources relate — where they agree, where they clash, and what you conclude from the difference.

¶1Introduction

Frames the conversation the sources are having, not just the topic, and states a thesis that takes a position across them.
Frame
"Researchers disagree about whether ____, but the evidence points to ____. Although ____ (Source A), ____ (Source B) shows that ____."
Example

Researchers disagree about whether school phone bans improve learning, but the evidence points to a narrower answer. Although Ford (2021) finds no average test-score gain, Liu (2022) shows that the gains concentrate among the lowest-performing students, which is exactly the group the policy was meant to help.

¶2Body 1 — what one source establishes

Presents a source's finding accurately, with attribution, and explains what it contributes to your claim. Never drop a quotation without introducing and then interpreting it.
Frame
"____ (Source A) establishes that ____. Because ____, this matters for ____: ____."
Example

Ford (2021) establishes that a school-wide phone ban did not raise average scores across a 4,000-student district. Because the average hides the distribution, this finding matters for policy design: a rule can look useless in aggregate while still helping the students at the bottom.

¶3Body 2 — what another source adds or challenges

Brings in a second source specifically against the first, and does the synthesis work: states the relationship in one sentence, then explains it.
Frame
"Yet ____ (Source B) complicates this. Where ____ finds ____, ____ finds ____. The difference comes from ____."
Example

Yet Liu (2022) complicates this picture. Where Ford measured every student, Liu separated the cohort by prior achievement and found that gains were real for the lowest quartile, whose average rose by a full letter grade. The difference comes from who the study counted, not from where it was conducted.

¶4Body 3 — your synthesis

Puts the sources into one idea of your own. This is the paragraph a grader reads to find out whether you actually thought about the sources or just lined them up.
Frame
"Read together, the sources suggest that ____. No single study supports this alone, but the pattern ____."
Example

Read together, the sources suggest that phone bans should be judged by who benefits, not by whether the average moves. No single study supports that claim alone, but the pattern — a flat mean and a rising floor — is exactly what a targeted rule would produce.

¶5Conclusion

States what a reader should now believe, acknowledges the limit of the evidence, and stops. No new source appears here.
Frame
"The evidence does not prove ____, but it does show ____. Schools weighing a ban should therefore ____."
Example

The evidence does not prove that phones should be banned everywhere, but it does show that the students a ban is meant to protect are the ones who gain. Schools weighing the policy should therefore measure the floor, not only the average.

中文要点(四类文体)
  • 议论文:一个立场,三条理由,必须有一段处理反方论点(先承认再反驳)。
  • 修辞分析:要参不要评。只说作者用了什么手法、对读者产生了什么效果,不表达你同意或反对。
  • 文学分析:用现在时态,绝不能复述故事情节;每个细节都要服务于你的解读。
  • 综合写作:不是把材料排队,而是说清两个来源的关系(一致、冲突、互补),最后给出你自己的结论。

3The thesis: formulas and good/bad models

One sentence that a reasonable person could disagree with, that names your reasons, and that tells the reader how the essay will be organised.

X. Although Y, Z because A, B, and C. Because A, B, and C, Z, although Y.

X = the situation or topic, in a few words. Y = the strongest opposing view, conceded. Z = your claim — the part someone could argue with. A, B, C = the reasons that become your body paragraphs, in the order they appear. If you can delete "although Y" and lose nothing, your thesis was not really arguable.

Prompt 1. Many districts start high school before 7:30 a.m. Should they start later?

✗ Weak thesis
School start times are a topic that many people have different opinions about, and it is important to look at both sides.
✓ Strong thesis
Although later start times complicate bus schedules, high schools should begin after 8:30 a.m. because adolescent sleep cycles shift later, early starts depress attendance, and groggy students learn less.

The weak version states no position and previews no structure — a grader learns nothing about the essay to come. The strong version concedes a real cost (Y), takes a side (Z), and lists three reasons (A, B, C) that will each become a body paragraph.

Prompt 2. Is social media harmful to teenagers?

✗ Weak thesis
Social media has good and bad effects on teenagers.
✓ Strong thesis
Although social media can connect isolated teenagers, it does more harm than good because platform algorithms reward outrage over accuracy, comparison culture erodes self-image, and late-night use steals the sleep that adolescent brains need.

Notice that the weak version could not be wrong. A thesis you cannot disagree with is a summary, not an argument.

Prompt 3. Analyse how a writer builds a case for civic responsibility in a public letter.

✗ Weak thesis
The author uses many rhetorical devices to make the letter persuasive and effective for the reader.
✓ Strong thesis
By naming the reader's own small choices before he names any duty, by shifting from "I" to "we" in the middle of the letter, and by closing on a question rather than a command, the author turns civic responsibility from an obligation into a shared identity the reader wants to accept.

In an analysis thesis, the "reasons" are strategies and the "claim" is their effect. Naming the strategies in order gives the reader the skeleton of your three body paragraphs.

中文要点(论点公式)
  • 标准公式:X. Although Y, Z because A, B, and C.(背景 + 让步反方 + 主张 + 三条理由)。
  • 好论点三条标准:有争议、具体、预示结构;能被反驳的才叫论点,不能被反驳的叫事实罗列。
  • “Although Y”这一句是关键:它证明你看到了反方,但还是选择站边。

4Inside a paragraph: TS → E → C → L

Every body paragraph runs the same four moves. Learn the engine and you can write one in any subject, under any time limit.

TS — Topic sentence
A claim, not a fact and not a summary. It tells the reader which piece of the thesis this paragraph will prove. If it could be true of any essay, it is too vague.
1 sentence
the paragraph's job in miniature
E — Evidence
The proof: a quotation, a statistic, an expert, an event. Always attributed (who said it, where). Keep it short — a phrase or a line, not a block.
1–2 sentences
no analysis here yet
C — Commentary
The most important sentences in the essay. Explain how the evidence proves the topic sentence — the reasoning, the "so what". Rule of thumb: at least two sentences of commentary for every one sentence of evidence.
2–3 sentences
the reasoning, not a repeat of the evidence
L — Link
Ties the paragraph back to the thesis and, if there is a next paragraph, points to it. One sentence is enough; do not summarise the paragraph again.
1 sentence
backs out to the thesis

Two annotated model paragraphs

TSTopic sentence EEvidence CCommentary LLink

Model 1 · Argumentative body paragraph (school start times)

TSLater start times would also change how much a first-period class actually learns, because a rested brain is a working brain.

EIn a 2019 study of 30,000 students published in Science Advances, schools that pushed the first bell to 8:45 a.m. reported a 4.5% rise in attendance and a measurable jump in the grades of students who had been struggling most.

CThe detail that matters is not the average gain but who gained: the students closest to failing improved furthest.

CThat pattern tells us the early bell was not merely inconvenient; it was quietly sorting students by how well their bodies happened to match the schedule. A bell that penalises sleep is, in effect, a rule that rewards one biology over another.

LIf learning is the point, then, a start time that suppresses it is the cheapest fix on the table.

Note the ratio: one sentence of evidence earns two sentences of commentary. The paragraph never quotes and runs — it explains why the number matters.

Model 2 · Literary-analysis body paragraph ("The Tell-Tale Heart")

TSThe narrator insists he is sane exactly where his own words confess the opposite.

EHe opens by asking "why will you say that I am mad?" and then calmly explains that a "pale blue eye, with a film over it" was reason enough to kill.

CThe question is answered by the explanation that follows it: a mind that treats an eye as a sufficient motive has already stopped reasoning the way sanity requires.

CHe is not lying so much as rehearsing — every clause re-argues a verdict he has already heard, which is why the story reads like a closing statement rather than a confession.

LRead this way, the story's real subject is not the murder but a mind's need to be believed.

Both paragraphs use present tense, both quote a short phrase, and both spend more words on the quotation's meaning than on the quotation itself.

中文要点(段落四步)
  • 段落公式:TS 主题句 → E 证据 → C 分析 → L 回扣,每段四步一次,五段文就是这个引擎重复使用。
  • 证据与分析比例至少 1 : 2。只引用不分析是全文最常见的失分点。
  • TS 必须是“主张”而不是“事实”;C 是解释“为什么这个证据能证明你的主张”,不是把证据换个说法重说一遍。

5Transition word bank

Transitions do one job: they tell the reader the logical relationship between two sentences. Pick by function, not by habit — "also" is not a substitute for thinking.

Illustration / Example · 举例

  • for example
  • for instance
  • to illustrate
  • namely
  • specifically
  • in particular
  • such as
  • as demonstrated by
  • consider
  • take the case of

Contrast · 对比

  • however
  • nevertheless
  • in contrast
  • on the contrary
  • conversely
  • whereas
  • yet
  • even so
  • unlike
  • instead

Cause & Effect · 因果

  • therefore
  • consequently
  • as a result
  • thus
  • hence
  • accordingly
  • for this reason
  • due to
  • leads to
  • it follows that

Addition / Sequence · 递进

  • furthermore
  • moreover
  • in addition
  • additionally
  • likewise
  • similarly
  • equally important
  • not only … but also
  • first / second / third
  • next

Concession · 让步

  • although
  • even though
  • though
  • despite
  • in spite of
  • admittedly
  • granted that
  • while it is true that
  • of course
  • even if

Conclusion · 结论

  • in conclusion
  • to conclude
  • in summary
  • ultimately
  • in the end
  • overall
  • in short
  • in sum
  • all things considered
  • on the whole

Two cautions. First, do not open every paragraph with a transition — a paragraph whose first word is "Furthermore" usually has a weak topic sentence. Second, transitions cannot repair a missing logical link: if the two sentences are not actually in that relationship, the word will read as decoration.

中文要点(过渡词)
  • 过渡词按“功能”选:举例用 for example,对比用 however,因果用 therefore,递进用 moreover,让步用 although,结论用 ultimately。
  • 段落开头不要每次都用过渡词;真正的连接靠的是主题句与论点的逻辑关系。
  • 过渡词不能掩盖逻辑缺口:如果两句本来就没有那种关系,硬加上去反而暢眼。
