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 life―whether academic, ocial, buine, or political-the only way to ucceed i to take a practical, rather than an idealitic point of view. PraGMATic behavior guarantee urvival, wherea idealitic view tend to be uperceded by impler, more immediate option.
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。
