为了帮助大家高效备考,小编为大家带来考试难点解析,希望对大家
GRE备考有所帮助。
1.无选项计算题 例: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个数的算术平均数是14。若其中9个数的算术平均数为9,则剩下的2个数的平均数是多少? GRE数学样题新题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NX。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。

2.多项选择题 例:In triangle ABC,the measure of angle A is 25 and the measure of angle B is greater than 90. Which of the following could be the measure of angle C? Indicate all possible values. A. 12 B. 15C. 45 D. 50 E.70 本题考察的是三角形的基本性质:内角和等于180度。由题意可知角A角B之和大于115度,由此可以得出A、B、C、D为正确答案。 由于GRE数学本身考察的数学知识并没有变难,所以这种题型仅仅是增加了考生思维的复杂性,并要求考生更加细心。
3.判断题 例:The symbol ? represents one of the four operations of addition, subtraction, multiplication, and division, and 3 ? 1 = 3. For each of the following equations, indicate whether the equation must be true, must be false, or could be either true or false. Equation Must Be True Must Be False Could Be True or False 6 ? 2 = 3 6 ? 2 = 4 6 ? 2 = 12 Click on your choices. Click on the answer box, then type in a number. Backspace to erase.
