新SAT考生们都知道，考官要求用事实，论据或修辞来分析文章。从写作的角度来说，按照西方修辞学的理论来说，一篇优秀的文章必须要具备以下三个要素：ethos,logos和pathos。今天我们主要介绍修辞中的三个要素。

　　(1)先看第一种为Ethos。

　　下面一段话是对它的解释，概况下就是指可信度，也就是说演讲者或是作者必须要让自己显得可信。

　　Ethos is appeal based on the character of the speaker. It is your personal credibility, the faith people have in your integrityand competency. It’s the trusts that inspire your emotional Bank Account. An ethos-driven document relies on the reputation of the author.

　　看下面这个例子：

　　原文再现Adapted from E.J. Dionne Jr., “A Call for National Service”? 2013 by Washington Post. Originally published July 03, 2013:

　　Last week,the Aspen Institute gathered a politically diverse group of Americans under the banner of the “Franklin Project,” named after Ben, to declare a commitment tooffering every American between the ages of 18 and 28 a chance to give a yearof service to the country. The opportunities would include service in our armed forces but also time spent educating our fellow citizens, bringing them healthcare and preventive services, working with the least advantaged among us, and conserving our environment.

　　满分段落：

　　Moreover, the author demonstrates a personal anecdote that “last week, the Aspen Institute gathered a politically diverse group of Americans…to declare a commitment to give a year of service to the country”, which provides a baseline for readers to find credence and credibility with the author’s argument.

　　(2)第二种为Logos指的是利用完全的逻辑来说服听众。

　　下面一段是对它的解释:

　　Logos is appeal based on logic or reason，the logic, the reasoning part of the presentation is the only legitimate way to win friends and influence people. So Logos contains not only logic, but also the fact that is not arguable valid able figure, the sufficient reasons reasonable structures and so on.

　　例如：

　　原文再现Adapted from E.J. Dionne Jr., “A Call for National Service”? 2013 by Washington Post. Originally published July 03, 2013：

　　Here is the sentence in the Declaration of Independence we always remember: “We hold thesetruths to be self-evident, that all men are created equal, that they areendowed by their Creator with certain unalienable Rights, that among these areLife, Liberty and the pursuit of Happiness.”

　　满分段落：

　　By referencing to authoritative source, E. J. Donnie Jr. in the first place builds a solid ground for his call for national service. Through quotation from one of the Founding Document, the Declaration of Independence, at the beginning of his argument, the uthor sets forth that the prerequisite of “our rights”, that is “all men are created equal”, is the fulfillment of our obligation to “pledge to each other our Lives, our Fortunes and our Sacred Honor”. It convinces the reader by logic reasoning that all the citizens should contribute to national service.

　　(3)第三种Pathos指的是情感。

　　也就是说作者或是演讲者通过煽动受众情绪来达到目的，即

　　Pathos is appeal based on emotion，the empathic side—it’s the feeling. It means that you are in the emotional that trust another person’s communication.

　　例如下文就完美地展现了pathos这一修辞的应用

　　Adapted from Paul Bogard, “Let There Be Dark.” ?2012 by Los Angeles Times. Originally published December 21, 2012.原文再现

　　In today’s crowded, louder, more fast-paced world, night’s darkness can provide solitude, quiet and stillness, qualities increasingly in short supply. Every religious tradition has considered darkness invaluable for a soulful life, and the chance to witness the universe has inspired artists, philosophers and everyday stargazers since time began. In a world awash with electric light...how would Van Gogh have given the world his “Starry Night”? Who knows what this vision of the night sky might inspire in each of us, in our children or grandchildren?

　　满分段落为：

　　Finally, Bogard makes subtle yet efficient use of rhetorical questioning to persuade his audience that natural darkness preservation is essential. He asks the readers to consider “what the vision of the night sky might inspire in each of us, in our children or grandchildren?” in a way that brutally plays to each of our emotions. By asking this question, Bogard draws out heartfelt ponderance from his readers about the affecting power of an untainted night sky. This rhetorical question tugs at the readers’ heartstrings; while the reader may have seen an unobscured night skyline before, the possibility that their child or grandchild will never get the chance sways them to see as Bogard sees. This strategy is definitively an appeal to pathos, forcing the audience to directly face an emotionally-charged inquiry that will surely spur some kind of response.

　　所以我们今后在分析新SAT写作的阅读文章中，在修辞法这一部分就可以着重观察下这三个要素，如果用到，我们就可以迅速识别并写到自己的作文中。
