如何写论点句

论证 / 政策论文：

由于[具体证据]，[谁]应当[具体行动]，而不是[通常的替代方案]。

文学或来源分析：

在[文本]中，[作者]为了[解释]而[做X]，这之所以重要，是因为[它如何改变我们对作品的读法]。

研究文章（目的，不是课堂论点）：

本研究检验在[总体]中，[变量A]是否[增加 / 减少 / 不影响][变量B]，因为[该设计能填补的空白]。

tells the reader how you will interpret the significance of the subject matter under discussion.

is a road map for the paper; in other words, it tells the reader what to expect from the rest of the paper.

A thesis is an interpretation of a question or subject, not the subject itself. The subject, or topic, of an essay might be World War II or Moby Dick; a thesis must then offer a way to understand the war or the novel.

makes a claim that others might dispute.

Your thesis is the central claim in your essay—your main insight or idea about your source or topic.

A strong thesis is arguable, which means a thoughtful reader could disagree with it and therefore needs your careful analysis of the evidence to understand how you arrived at this claim.

You arrive at your thesis by examining and analyzing the evidence available to you, which might be text or other types of source material.

A strong thesis will be arguable rather than descriptive, and it will be the right scope for the essay you are writing.

Almost all of us—even if we don’t do it consciously—look early in an essay for a one- or two-sentence condensation of the argument or analysis that is to follow.

Almost all assignments, no matter how complicated, can be reduced to a single question.

Every paper requires one. Assignments that ask you to write personal responses or to explore a subject don’t want you to seem to pre-judge the issues. Essays of literary interpretation often want you to be aware of many effects rather than seeming to box yourself into one view of the text.

A thesis statement must come at the end of the first paragraph. This is a natural position for a statement of focus, but it’s not the only one. Some theses can be stated in the opening sentences of an essay; others need a paragraph or two of introduction; others can’t be fully formulated until the end.

A thesis statement must be one sentence in length, no matter how many clauses it contains. Clear writing is more important than rules like these. Use two or three sentences if you need them. A complex argument may require a whole tightly-knit paragraph to make its initial statement of position.

You can’t start writing an essay until you have a perfect thesis statement. It may be advisable to draft a hypothesis or tentative thesis statement near the start of a big project, but changing and refining a thesis is a main task of thinking your way through your ideas as you write a paper. And some essay projects need to explore the question in depth without being locked in before they can provide even a tentative answer.

A thesis statement must give three points of support. It should indicate that the essay will explain and give evidence for its assertion, but points don’t need to come in any specific number.

Do I answer the question?

Have I taken a position that others might challenge or oppose?

Is my thesis statement specific enough?

Does my thesis pass the “So what?” test?

Does my essay support my thesis specifically and without wandering?

Does my thesis pass the “how and why?” test?

Is the thesis truly arguable? Does it speak to a genuine dilemma in the source, or would most readers automatically agree with it?

Is the thesis too obvious? Again, would most or all readers agree with it without needing to see your argument?

Is the thesis complex enough to require a whole essay's worth of argument?

Is the thesis supportable with evidence from the text rather than with generalizations or outside research?

Would anyone want to read a paper in which this thesis was developed? That is, can you explain what this paper is adding to our understanding of a problem, question, or topic?

Social media impacts public awareness in both positive and negative ways.

Because not every voice on social media is reliable, people have become much more critical consumers of information, and thus, more informed voters.

不是论点（欣赏）：

Mark Twain’s Huckleberry Finn is a great American novel.

观察，仍不够可争议：

In Huckleberry Finn, Mark Twain develops a contrast between life on the river and life on the shore.

论点（对该对照的解释）：

Through its contrasting river and shore scenes, Twain’s Huckleberry Finn suggests that to find the true expression of American democratic ideals, one must leave “civilized” society and go back to nature.

描述性（不可争议）：

While Sandel argues that pursuing perfection through genetic engineering would decrease our sense of humility, he claims that the sense of solidarity we would lose is also important.

过宽（可争议，难以支撑）：

Michael Sandel’s arguments about genetic engineering do not take into consideration all the relevant issues.

可争议的分析性主张：

While Sandel argues persuasively that our instinct to “remake” (54) ourselves into something ever more perfect is a problem, his belief that we can always draw a line between what is medically necessary and what makes us simply “better than well” (51) is less convincing.

可争议的规范性主张：

Given Sandel’s argument against genetic enhancement, we should not allow parents to decide on using Human Growth Hormone for their children.

题目，不是论点：

Sugar consumption.

更窄的题目，仍无主张：

Reducing sugar consumption by elementary school children.

含糊立场：

More attention should be paid to the food and beverage choices available to elementary school children.

具体事实，仍不是论点：

Experts estimate that half of elementary school children consume nine times the recommended daily allowance of sugar.

论点（断言加支撑）：

Because half of all American elementary school children consume nine times the recommended daily allowance of sugar, schools should be required to replace the beverages in soda machines with healthy alternatives.

弱（无立场；课堂产品）：

There are some negative and positive aspects to the Banana Herb Tea Supplement.

强（立场+机制）：

Because Banana Herb Tea Supplement promotes rapid weight loss that results in the loss of muscle and lean body mass, it poses a potential danger to customers.

弱（仅观察）：

My family is an extended family.

强（经验对照被广泛接受的看法）：

While most American families would view consanguineal marriage as a threat to the nuclear family structure, many Iranian families, like my own, believe that these marriages help reinforce kinship ties in an extended family.

弱（两个未接合的想法）：

Companies need to exploit the marketing potential of the Internet, and Web pages can provide both advertising and customer support.

强（第二个想法服务于第一个）：

Because the Internet is filled with tremendous marketing potential, companies should exploit this potential by using Web pages that offer both advertising and customer support.

陈词滥调：

Shakespeare was the world’s greatest playwright.

引人好奇：

The success of the last scene in Midsummer Night’s Dream comes from subtle linguistic and theatrical references to Elizabeth’s position as queen.

预告+裁决：

This essay will show that the North American Free Trade agreement was a disaster for the Canadian furniture industry.

主张+方法+日期：

Neither neo-protectionism nor post-industrial theory explains the steep reversal of fortune for the Canadian furniture industry in the period 1988-1994. Data on productivity, profits, and employment, however, can be closely correlated with provisions of the North American Free Trade Agreement that took effect in the same period.

笼统、含糊：

Having an official policy on euthanasia just causes problems, as the Dutch example shows.

足够复杂（Toronto原词，包括“Hamarckian”）：

Dutch laws on euthanasia have been rightly praised for their attention to the principles of self-determination. Recent cases, however, show that they have not been able to deal adequately with issues involving technological intervention of unconscious patients. Hamarckian strategies can solve at least the question of assignation of rights.

过宽：

World hunger has many causes and effects.

IU教学例子（虚构国家）：

Hunger persists in Glandelinia because jobs are scarce and farming in the infertile soil is rarely profitable.

弱（用and连接的两个主旨）：

Healthcare reform must be addressed because so many Americans are uninsured or without adequate coverage, and politicians must work together to ensure new legislation is passed.

强（一个想法）：

Politicians must work together to reform healthcare because too many Americans are without sufficient coverage.

Banning cigarette smoking in public places is an effective intervention to improve the public’s health by helping to reduce the dangers of second-hand smoke on non-smokers, encouraging current smokers to quit, and reducing healthcare costs.
