WHICH ONE类：题干中明确要求考生做二选一的选择，比如：
In any realm of lifewhether academic, social, business, or political-the only way to succeed is to take a practical, rather than an idealistic point of view. PraGMATic behavior guarantees survival, whereas idealistic views tend to be superceded by simpler, more immediate options.
由于是二选一，因而作文者有三种回应倾向：选A，选B或A，B中和。那么我们可以提炼出两种基本模式：
1、单选：1、选A的基本理由;2、选A的`好处;3、相较之A，选B有什么坏处。
2、双选：1、选A的基本理由和好处;2、选B的基本理由和好处;3、A和B同时兼备的好处。
由于GRE作文开放式的话题，很少有东西全坏或全好，所以奉劝考生尽量学会使用双选模式，但是有志于创新的同学可以尝试用单选，它往往让你的作文另类而出彩，前面已有范文作过示范，请予以参照。下面的范文选用重点掌握的双选模式，读者注意其论证构思的过程。
As one of the famous philosophers ever writes,the dream leads our sights toward the future, and the practice make our sense recognize how far away we still have to strive for.During the recent decades, experts gradually have been divided into two opposite cults respectively holds their own belief of idealism and empiricism, and through thousands of fervid controversies the latter seems having dominated the optimal status after showing the corroborative evidence stems from the practical exemplar in the process of society constructions. But, in my point of view, in this practical and competitive world, being practical is essential to ones survival, yet ideals give us a direction in our pursuit of success.
