一、走进生活1、小明有一些邮票,他把邮票的一半多2张送给小红,还剩下50张.他原来有多少张2、小明和小红共有50张邮票,

1、设原来有a张,则 a-（0.5a+2）=50 求得a=104
所以他原来有104张.
2、设小明原来有b张,则小红原来有（50-b）张,依题意有
b-8=50-b+8 求得 b=33 所以小明原来有33张
3.Last weekend,I studyed English on saturday morning.On last saturday afternoon,I played foodball with my friends.And I helped my mother cook dinner.In the evening,I stayed at home.On last Sunday morning,I watched TV.And in the afternoon I went shopping with my mother.I studyed at home all that night.That was my weekend.
再问： 数学那个有简单点的吗
再答： 看来你没学那么深入所以比较难接受哈.. 1、（50+2）×2=104 2、后来两个人邮票数相等，相等后每人有50÷2=25张 小明原有25+8=33 小红原有50-33=17 或 25-8=17张
