AI：关于电脑是否改善人们的生活的话题
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 since 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.”
数学：
1. 一个椭圆内切于一个长方形，椭圆面积公式已给出，好像是area=∏r^2, 长方形的面积是12，对角线的长度是5，求此椭圆的面积。
2. 在数抽上，x 在y z的左侧，问：xyz>0?
① Xy>0
② Xz>0
3. 三个人做一件事分别要x y z 分钟，问：三个人一起做要几分钟？
4. 一条抛物线，在横轴上交于-3，5，最高点的纵坐标是**（不记得了，呜）问：与Y轴交点正还是负？
5. （3！4！）！有几个连续的0？
CR:
1． 养狗可以让人们经常溜狗，增加运动，从而减轻精神压力和降血压，一地区有很多人养狗，为什么那个地区人的压力很大血压很高？
我选的是：养狗只有对那些会经常溜狗，增加运动的人才有减轻精神压力和降血压的效果。

1．有一篇是GWD里《学者对印地安部落社会结构的假设》那篇，题目不太一样而已
In the fourteenth and fifteenth centuries, many Western Pueblo settlements in what is now the southwestern United States may have possessed distinctly hierarchical organizational structures. These communities’ agricultural systems ―which were “intensive” in the use of labor rather than “extensive” in area ―may have given rise to political leadership that managed both labor and food resources. That formal management of food resources was needed is suggested by the large size of storage spaces located around some communal Great Kivas (underground ceremonial chambers). Though no direct evidence exists that such spaces were used to store food, Western Pueblo communities lacking sufficient arable land to support their populations could have preserved the necessary extra food, including imported foodstuffs, in such apparently communal spaces.
Moreover, evidence of specialization in producing raw materials and in manufacturing ceramics and textiles indicates differentiation of labor within and between communities. The organizational and managerial demands of such specialization strengthen the possibility that a decision making elite existed, an elite whose control over labor, the use of community surpluses, and the acquisition of imported goods would have led to a concentration of economic resources in their own hands. Evidence for differential distribution of wealth is found in burials of the period: some include large quantities of pottery, jewelry, and other artifacts, whereas others from the same sites lack any such materials.
2．还有一篇是说两种binding的优缺点，主要侧重写第二种比第一种好，具体是什么记不太清了
