所谓proposition主旨题，顾名思义，就是考察文章段落或全篇内容的主旨大意的题目。大学路小编给大家带来了SAT考试写作主旨中的美式价值观文法介绍相关文章，一起来看一下吧。
OG中(P136)将proposition做了如下定义：
Proposition questions require you to think about the “big ideas” in the passage and how they can be refined to better clarify and structure the writer’s message.
主旨题的提问形式主要有以下几种：
Which choice most effectively establishes the central claim of the passage?
Which sentence most effectively establishes the main topic of the paragraph?
在做此类题目的时候，我们需要注意的是以下几点信息：
Thesis statement expresses the main idea of the overall passage.
Topic sentences are used to help structure and clarify the focus of the paragraphs. (常规段落分论点出现在段首或段末，非常规段分论点出现在段中。)
Claims and counterclaims are features specific to arguments.
新SAT文法部分的文章，仅就文本而言(遣词造句，修辞手法甚至标点符号)，经过了深思熟虑，精心布局，字斟句酌，其传达的理念也是我们需要去把握的，本文将从题目中(文章体裁以argumentative, informative , narrative为例)对新SAT想传达的美式价值观进行一个简要的分析。
Argument
Passage typeStyle
ArgumentativePresents opinions and facts, includes analysis of evidence, can include more forceful language
KH：Judithe Hernandez and the Chicana Artistic Voice
Judithe Hernandez’s art career began in Los Angeles during the socially and politically turbulent 1960s. While enrolled as a graduate student at the Otis Art Institute in Los Angeles, Hernandez met fellow student Carlos Almaraz, one of the founding members of the Chicano artist collective known as “Los Four.” At Almarez’s request, Hernandez joined “Los Four” as its fifth, and only female, member. Hernandez became well known for her work with this revolutionary group of artists, who are credited with establishing Chicano art as its own distinctive school of (US) American art. 3 Less known but equally important, however, is the role Hernandez played in providing a female voice within what was at that time a predominantly male Chicano art movement.
Question 3
Which choice most effectively establishes the central claim of the passage?
(A)NO CHANGE
(B)The Chicano Movement, also known as “EI Movimiento,” began in the 1940s with the explicit goat of empowering Mexican-Americans.
(C)Judithe Hernandez was born to progressive Mexican-American in Los Angeles that encouraged her involvement in the arts from any early age.

这个选项肯定了政府，非盈利组织和市民合作在防止蝙蝠受到进一步杀害方面起到的关键作用。这也和恩格斯所说的“历史合力”是一个概念：要充分调动包括社区、家庭、学校、公司、NGO组织等在内的各种社会资源来形成蔚然成风的合力。至于提及动物的文本，基本上都会向考生传递保护濒危动物的正能量。
Narrative
Passage typeStyle

KH： Personal Anthropology
Ethnographers work anywhere from communities in small villages to bustling cities, but their work is always the same: listening to someone else’s story. A subfield of anthropology, ethnography is the study of people and the cultures in which they live. While an objective approach to collecting and sharing information is traditionally encouraged, 3 anthropology professor Ruth Behar believes that integrating her personal experience into her work is not only inevitable but valuable. Doing so, Behar argues, allows readers to better connect with her work.
Which choice most effectively states the central idea developed throughout the passage?
A)NO CHANGE
B)some anthropologists believe that a level-headed, detached observation is the best way to approach ethnography.
C)some anthropologists believe that information about anthropological subjects should not be catalogued traditionally.
D)anthropology professor Ruth Behar believes in working directly with people when studying
正确选项：A
这里题提及的露丝·贝哈(Ruth Behar，1956— )，是犹太古巴裔美国作家，密歇根大学人类学系教授。露丝·贝哈的书，有一个共同的他点，就是会评估自身情感和经验对研究及写作的影响。选项中提及将个人经验融入作品中不仅是不可避免的，而且是大有价值的。这里传递出来的也是美国教育体系中知识和实践(融合社会实践和知情意行各个维度)。
这些文本，有的是美国最重要的历史文献，有的是人物传记，有的是科学的普及文章。上承古希腊文明，下启工业文明和信息文明，涵盖极为广博。这些文献阐释的公平、正义、平等、权利、自由、民主、法治、尊严、幸福、信仰、道德等等，从不同的角度，集合或定义的是美国文明的概念、程序、规则和本质等，也是人类共有的精神养分，无论是对跨进美国名校门槛，还是为人处事，都是不可或缺的。
