在gmat備考之中，大家都會(huì)遇到gmat寫(xiě)作中的一些問(wèn)題，經(jīng)過(guò)網(wǎng)友的分析總結(jié)，下面就來(lái)看看AA中的“七宗罪”可以按照論證的原因、結(jié)果、論證過(guò)程三部分，歸為三個(gè)類別：因、果、證，接著就來(lái)看看具體情況。

　　1、因
　　就是原因上的問(wèn)題，有以下三個(gè)：
　　可疑調(diào)查
　　樣本不足
　　結(jié)論無(wú)據(jù)

　　2、果
　　就是結(jié)論上的問(wèn)題，有以下兩個(gè)：
　　無(wú)因果聯(lián)系
　　二者擇一

　　3、證
　　就是論證過(guò)程上的問(wèn)題，有以下兩個(gè)，縱向橫向各一個(gè)：
　　錯(cuò)誤類比(橫向)
　　時(shí)地全等(縱向)
　　這樣，只要記住了三字訣：因、果、證，就很容易記牢全部七宗罪了。


　　順便分析一下本月JJ的一篇AA：
　　“Our total sales have increased this year by 20 percent since we added a pharmacy section to our
　　grocery store. Clearly, the customer’s main concern is the convenience afforded by one-stop
　　shopping. // 無(wú)因果聯(lián)系，可能另有他因。 The surest way to increase our profits over the next couple
　　of years, therefore, is to add a clothing department along with an automotive supplies and repair
　　shop. We should also plan to continue adding new departments and services, such as a restaurant
　　and a garden shop, in subsequent years. // 時(shí)地全等 Being the only store in the area that offers such a range of services will give us a competitive advantage over other local stores.” // 結(jié)論無(wú)據(jù)
