数学正常发挥 语文 实在是太令我伤心了 prep三次了 从来没有过这种分数 不知道怎么回事 做题的时候感觉特别陌生 所以就不误导大家了 贡献少量作文和数学机经 希望后来的同学加油 AA ：The following appeared in the editorial section of a local newspaper. “In the first four years that Montoya has served as mayor of the city of San Perdito, the population has decreased and the unemployment rate has increased. Two businesses have closed for each new business that has opened. Under Varro, who served as mayor for four years before Montoya, the unemployment rate decreased and the population increased. Clearly, the residents of San Perdito would be best served if they voted Montoya out of office and reelected Varro.” AI ：就是前面有网友提到过的科技是吧人们分开多一点还是为人们服务多一点 数学只记得 有一题是等差数列 1开始到n 差是1 求S(2n)-S(n) 答案我算的是S(n)+n^2 其它的暂时想不起来了 心情不好 等想起来再发吧 |
