2.New technologies often begin by (i) ________ what has gone before, and they change the world later. Think how long it took power-using companies to recognize that with electricity they did not need to cluster their machinery around the power source, as in the days of steam. Instead, power could be (ii) ________ their processes. In that sense, many of today‘s computer networks are still in the steam age. Their full potential remains unrealized.（摘自新GRE样题第15题）

此题正确选项为mimicking和transmitted to。限于篇幅这里不作详解。
在样卷中这样的题有9道，空格数从1个到3个不等，于每个空格所对应的选项数目也是从3个到5个不（单空题对应5个选项，多空题每空对应3个选项），这样的题型灵活性大大提高，与现行的考试形式相比，每个空格的选择相对独立，阅读量增大。

另一变化是对于“列表选择题”没有ABCD之类的选项，机考将在电脑屏幕上直接点选，这也更加符合ETS的改革目标，即更多的采用计算机功能来方便考试。
从ETS所提供的样题来看，数学部分所考察的数学知识范围、运算复杂程度基本没有变化，而主要是在题目数量和比例、题型方面做了一些改动。下面针对样题中出现的一些新题型做一简单分析：
1.出现了无选项计算题，即要求考生根据题目条件直接计算答案，而不能从已有选项中排除。这意味着对于考生解题思路的要求更高了，对于有些比较复杂的题目如果采取这种形式，考生将无法从选项中获得提示。
例1：The total amount of Judy's water bill for the last quarter of the year was $40.50. The bill consisted of a fixed charge of $13.50 plus a charge of $0.0075 per gallon for the water used in the quarter. For how many gallons of water was Judy charged for the quarter?
从数学知识来说，本题基本相当于中国小学高年级数学应用题的难度，在阅读理解准确的前提下解题应该没有太大难度。本题可以看作是ETS提出的“增加日常真实背景问题”的一个例子。
例2：The average (arithmetic mean) of the 11 numbers in a list is 14. If the average of 9 of the numbers in the list is 9, what is the average of the other 2 numbers?
11个数的算术平均是14，若其中9个数的算术平均为9，则剩下的2个数的平均数是多少？本题考察的是考生对算术平均值这一概念的认识。如果N个数的算术平均是X，则这N个数之和为N×X。只要掌握了这一点对于那些考察算术平均值的题目就应该迎刃而解了。从这里我们也可以看出在改革后的GRE数学中，对于一些统计学数值（比如算术平均、极差、标准方差、中数等）的理解要求提高了。
我们再看这样一道比较大小的题目：
例3：
Quantity A: The standard deviation of a set of 5 different integers each of which is between 0-10
Quantity B: The standard deviation of a set of 5 different integers each of which is between 10-20
A. Quantity A is greater. B. Quantity B is greater. C. The two quantities are equal.
