首先分析原因，原因有三個：第一可疑調查；第二樣本不足；第三結論無據。

　　然后分析結果，結論上的問題：第一無因果聯系；第二，二者擇一。

　　分析論證，這個是論證過程上的問題，有以下兩個，縱向橫向各一個：錯誤類比 (橫向)，時地全等(縱向)

　　因此，因、果、證這三個要素就成為了GMAT作文的問題了。為了進一步夯實GMAT作文的記憶方法，我們下面講解一篇案例

　　下面是一篇GMAT作文：

　　“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. // 無因果聯系，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.” // 結論無據

　　掌握了GMAT作文問題的三個方面，提高GMAT作文水平也會變得很容易，我們要在大量的實戰中，不斷地總結GMAT作文的經驗，加以分析總結，增強GMAT作文記憶方法。

　　想要真正的通過這些分析掌握GMAT作文成績提高的方法，大家需要更多的實踐練習才能達到。
