GRE寫作段落核心句的整理

　　第一段：開頭段。主要是歸納論點(diǎn)，說明論點(diǎn)有問題，存在邏輯漏洞，準(zhǔn)備發(fā)起進(jìn)攻

　　第一層：

　　This argument concludes/recommends/argues that…

　　第二層：

　　To support this conclusion the writer cites…/points out that…

　　第三層：

　　However, this argument suffers from several critical flaws and is therefore unconvincing/ unpersuasive as it stands.

　　第二段和第三段甚至第四段：分類別去攻擊各個(gè)邏輯錯(cuò)誤。(以因果關(guān)系類錯(cuò)誤為例)One problem with the argument is that, the editorial observes a correlation between… and…, then concludes that the former is the cause of the latter. However, the editorial fails to rule out other possible explanations for…For example,… Any of these factors, or other social, political or economic factors, might lead to…Without ruling out all other such factors it is unfair to conclude that…

　　第五段：結(jié)尾段

　　作者的結(jié)論似乎是合理的，但是通過論證，不是這樣的。因此作者在做出決定之前，應(yīng)該還要考慮其他情況。我們通過一篇文章作為實(shí)例來介紹Argument的論證步驟和論證方法以及文章結(jié)構(gòu)。

　　In the final analysis, the letter's author fails to adequately support the recommendation that…To bolster the argument, the arguer must provide detailed demographic/statistical evidence showing that…The author must also provide evidence--perhaps by way writer cites…/points out that…
