| | | 到2035年,我国要发展成为体育强国.北京市曾在2008年和2022年分别举办了第29届夏季奥运会和第24届冬季奥运会, |
| | | 因此成为世界上第一个既举办过夏季奥运会又举办过冬季奥运会的城市.现在用集合的观点来分析这个问题,如图1-8所示,我们用集合U表示世界上所有的城市,用集合A表示到2022年年底举办过夏季奥运会的城市,用集合B表示到2022年年底举办过冬季奥运会的城市. |
| | | </p> |
| | | |
| | | <p> |
| | | (1) 图中哪部分表示既举办过夏季奥运会又举办过冬季奥运会的城市? |

| | | 再如,集合M={1,2},集合P={1,2,3},集合Q={1,2,5,6},则集合M中的元素既是集合P中的元素,又是集合Q中的元素.集合M是集合P和集合Q中的所有公共元素组成的集合,如图1-10所示. |
