作文：AI：constant innovations and changes will do harm to the organizations as well as hlep them
         AA:  “Currently, more professional accountants use SmartPro accounting software than any other brand. However, in the market for personal accounting software for non-professionals to use in preparing their income tax returns, many of our competitors are outselling us. In surveys, our professional customers repeatedly say that they have chosen SmartPro Software because our most sophisticated software products include more advanced special features than competing brands. Therefore, the most effective way for us to increase sales of our personal accounting software for home users would clearly be to add the advanced special features that our professional software products currently offer.”

数学：大半都是JJ的，补充下新的
1。 f(x)=（x-1)(x+2)[(1-k)x+(k+2)], k是一个常数，问K 的值
条件1：f(x)=0 有2个解
条件2：(x+2)^2是f(x)的一个factor
答案：选B，从1可得K=1or 0, 从2可得k=0 .

语文：阅读：有一篇讲对是否要在北美引入大型动物（已灭绝，如猛犸，剑齿虎等）的讨论。一屏半，说大型动物能很有效的控制其他物种来平衡生态，还有能通过这个提议来增加ecotourism（考点）来增加收入。
但有人也质疑这个提议的可行性，毕竟气候等已经早今非昔比等。

阅读： ROI　和　market share,请参考JJ
阅读： 鸭子那篇（讲动物体型和home range size的关系），虽然我看到了，但是觉得还是有点难，有时间大家再多看看。

逻辑和语法我估计错很多。。。导致700分的悲剧。。。不堪回首，不回忆了，大家加油！
