  导语:小编抽取了10个经典GRE数学题型来和大家分享,希望能对大家的学习带来一定的帮助。

  1,l1, l2 and l3 are three lines in space

  The number of points at The number of points at

  which lines l1 and l2 intersect which lines l2 and l3 intersect

  1.三条任意直线,L1和L2的交点的个数与L2和L3的交点的个数没关。

 

  2. The number of 1/4-inch lengths in 1

  a 4-inch length

  2,是问4英尺中有多少个1/4英尺,应该是16个,所以是A

 

  3. The maximun number of solid cubes 治癫痫病好的专科医院是哪家4

  having edges of length 1/2 meter that

  can be placed inside a cubical box

  having inside edges of length 1 meter

  3边长为1的立方体里最多能放下几个边长为1/2的立方体,当然是8个咯

 

  4. Cube C has volume 8 cubic centimeters

  The area of one of the faces of cube C 3 square centimeters

  4立方体体积是8,那一个面的面积当然是4咯

 

  5. Ms.Smith got an 8 percent cost-of-living raise of $20 per week

  Ms.Smith's new weekly salary 癫痫病老发作的原因$260

  5 x*0.08=20,那x+20=270>260

 

  6. On a certain number live, if -7 is a distance of 4 from n and 7 is a distance of 18

  from n then n=

  A.25 B.11 C.3 D.-3 E-11

  6应该是-11

 

  7. For all real numbers a and b. if a·b=a(a+b), then a·(a·b)=

  A. a2+ab B a2+ab+a C a2+a+b D a3+a2b E a3+a2b+a2

  注:a2表示a平方,a3表示a立方

  7新定义的运算a·b=a(a+b), 那a·(a·b)=a·(aa+ab)=a(a+aa+ab)=aa+aaa+aab

  8.secretary typed 6 letters,each of which had either 1 or 2 pages.If the secretary typed 10 pages in all, how many of the letters had 2 pages?

  A 1 B 2 C 3 D 4 E 5

  答案是D,题目我都看不懂,是啥意思呢?

  这是说秘书打六封信,没一封信要1页或者两页。如果秘书总共打了10页,那么有多少封信是两页?

  解答:设有x封,则2x+(6-x)=10,解得x=4.

 

  9 how many of the five numbers above are each equal to the product of an integer and an odd integer that greater than 1?

  这五个数是:2 6 8 14 16

  a.none b.one c.two d.there e.four

  我觉得这道题除了2不可能,其它四个数都有可能.可答案是c,想问大家为什么?

  题目意思是这5个数哪些可以是2个>1的数的积,一个是奇数,一个是整数,只有6和14的因数中有奇数,所以C.

 

  10 这句话大家看该怎样列式子呢?这是一道图表题.

  what was the approximate percent increase in personal income from 1965 to 1970?

  是这样(1970-1965)/1965还是(1970-1965)/1970这样?

  是这样:(1970-1965)/1965

 

  以上即是备考新gre数学易错题型介绍,希望对大家的GRE数学考试有所帮助。GRE数学考试中也有难点,这就需要我们努力攻克,争取把我们的优势发挥到最好。
