没法看的成绩,记得一点awa jj AA.B8. The following appeared in a presentation by the chief production manager of a machine parts manufacturing company at a management meeting: “Our factory in Cookville is our most advanced and efficient. It is capable of producing ten drill bits for each dollar of production costs, whereas none of our other factories can produce more than seven drill bits per dollar of production costs. Therefore, we can reduce our overall drill bit production costs by devoting the Cookville factory entirely to drill bit production. Since reducing the production costs of individual machine parts is the only way to achieve our larger goal of reducing our overall production costs, dedicating the Cookville factory entirely to drill bit production and shifting all other machine part production to our other factories will help us to attain that larger goal.” AI没找到但很简单:有人认为我们太依赖计算机了,而另一些人认为计算机在不断地改善这人们的生活。 V 在低分区,有个长文章好像是讲南北战争时期,林肯对于黑人解放起的作用,有一个组织(叫AA×××什么的)的观点,另一个人提出黑人才是推动黑人解放的原动力……不误导了。见到它还以为进了高分区结果成绩一出就傻了! 想起些数学: 在平面直角坐标系中一条直线斜率是否为证:1)与y=-x交于一点 2)y=x没有交点 。个人认为是B。 有一些男人和女人,人数分别是三千多和5千多,求女比男多的数与男人数的比最接近哪个数。是个近似题,保险些是具体按数作除法,不过好像考察的是合理估算和近似。 一群高中生,学A课的必学B课,学C课的必不学A课,给了学B的人数和同时学C与B的人数,好像还有个条件(可能是没学A的B的人数),求至少学一门的人数。想不起来了。 又记起个数学: DS:X、Y、Z、是(正)整数,问x+y是不是偶数? 1)x+z是偶数 2)y+z是偶数 我的答案:C,由1)x、z同偶或同奇,2)y、z同偶或同奇,单独都不能判断x+y奇偶性。但联立时:若z为偶则x偶且y也偶,得x+y为偶,若z为奇数,则x与y同是奇数,x+y为偶数。故选c。
