　　考试形式

　　The Analytical Writing Assessment (AWA) consists of one 30-minute writing task called the Analysis of an Argument. In this section, you must read a brief argument, analyze the reasoning behind it, and then write a critique of the argument.

　　审题要求

　　The following appeared as part of an article in a daily newspaper：

　　"The computerized on-board warning system that will be installed in commercial airliners will virtually solve the problem of midair plane collisions. One plane’s warning system can receive signals from another’s transponder—a radio set that signals a plane’s course—in order to determine the likelihood of a collision and recommend evasive action. "

　　Discuss how well reasoned you find this argument. In your discussion, be sure to analyze the line of reasoning and the use of evidence in the argument. For example, you may need to consider what questionable assumptions underlie the thinking and what alternative explanations or counterexamples might weaken the conclusion. You can also discuss what sort of evidence would strengthen or refute the argument, what changes in the argument would make it more logically sound, and what, if anything, would help you better evaluate its conclusion.

　　审题步骤

　　1. 整理题目逻辑链：找到文章的结论和前提

　　→结论：第1句;前提：第2句

　　2. 找到题目逻辑错误：默认前提对，找到结论不成立的原因

　　(为达到均分4-4.5分需要至少找到2个逻辑错误)

　　→1)有可能飞机碰撞事故由飞行员操控失误导致

　　2)warning system只装在了商用飞机上，而没有装在其他种类的飞机上，从而导致了碰撞事故

　　3)可能是天气因素导致飞机失控从而发生事故，与warning system无关

　　GMAT写作解题策略

　　开头段模板

　　Merely based on unfounded assumptions and dubious (suspicious) evidence, the statement draws a conclusion that_____. To substantiate (support) the conclusion, the arguer points out evidence that_____. In addition, he indicates that_____. (Furthermore, he cites the result of a survey in support of his recommendation). At first glance, the author’s argument appears to be convincing, but further reflection reveals that it omits some essential concerns that should be addressed to substantiate the argument. From my point of view, this argument suffers from 2/3 major logical flaws.

　　结尾段：再次指出文章逻辑有严重缺陷

　　结尾段模板

　　To sum up, this arguer fails to substantiate his claim that_____, because the evidence cited in the analysis does not lend strong support to what the arguer maintains. Therefore, if the argument had included the given factors discussed above, it would have been more thorough and logically acceptable.
