作文狗狗：
AA:
The following appeared as part of an annual report sent to stockholders by Olympic Foods, a processor of frozen foods.
“Over time, the costs of processing go down because as organizations learn how to do things better, they become more efficient. In color film processing, for example, the cost of a 3-by-5-inch print fell from 50 cents for five-day service in 1970 to 20 cents for one-day service in 1984. The same principle applies to the processing of food. And 40since Olympic Foods will soon celebrate its twenty-fifth birthday, we can expect that our long experience will enable us to minimize costs and thus maximize profits.”

Employers should prohibit employees from engaging in unhealthy behaviors, both at work place and in their personal lives.

LZ好厉害 拜一个

数学第二题 三角形高交于一点的题 我想选B.
最后一个 韦恩图题 应该是 7人吧..

根据 AUBUC=A+B+C-AB-AC-BC+ABC

所以AB+BC+AC=A+B+C-ABC-AUBUC=21+1-15=7

同学们纠正我~~~~~~

三角形这个同意你~我也觉得是B，用两边之和大于第三边，而A反而退不出~

、DS：某人有3种钱（或者票子，忘记了），面值分别是1,5,10。某人一共有60（90？）元钱，问你能否确定三种面值的钱各有多少？
1）5元纸币有6张。
2）1元纸币的张数是10元纸币的2倍


应该是90元吧 不然B推不出的...
