2011-11-16 05:04:10
2011新gre考试实施以来,不仅对写作部分茫然不知所措,就连我们所擅长的数学也甚是担忧,相信这其中的原因还是由于考生在新gre数学复习时没有把基础打牢。如果新版gre数学基本考点都没有复习到,如何能拿到分数呢?所以说,想要新版gre数学考好,复习的时候一定要把基本概念和重要考点都弄扎实。

  Set

  A set is a collection of objects or things. Each object in a set a member or element of that set.Size of a set is the number of members in the set.

  Example:

  The set of even numbers between 2 and 10 is of size 5:{2,4,6,8,10}.

  The set of primes between 2 and 10 is of size 4:{2,3,5,7}.

  Remember:

  Each member of set A belongs to A or is in the set A.

  A set can not have repeating member:{1,3,1,2}is not a set.

  Rearranging the order of the members does not change the set:{1,2,3}is same as{3,2,1}.

  由于美国数学基础教育的难度增加导致数学考试越来越难,但新gre数学复习考点都是高中时候学到的知识点,考生不要过于紧张,把基本概念弄明白,再记住一些新版gre数学必备的词汇,那么相信新版gre数学应该没有问题。
