集合是研究高中数学问题的基础和工具,高考中对集合的考查主要集中在集合关系与集合运算上,重点是以下几类典型问题.此类试题一般是给出两个集合,判断它们之间的包含(或真包含)关系,在多数情况下,须对给出的集合进行化简,使集合的元素更明确.

The collection is the foundation and tool for the study of math problems in high school. The examination of the collection in the college entrance examination mainly focuses on the collection relations and the collection operations, with emphasis on the following types of typical problems. Such questions generally give two sets, Contains (or really contains) the relationship, in most cases, the collection must be reduced to make the elements of the collection more specific.
