今天换裤子了。 数学,Q50。有道题3^x/9^2Y=?,a, x-2Y=6, b, x-4y=0,我选的A。 还有一道题说有个正方体,里面嵌入了一个球,球面和立方体相切,然后球的直径是6,问“正方体内最长的两点的长度”,我选的6*根号3. 还有一题是说,有个group要凑钱开派对,然后,有X个人,总共需要D数目的钱,但是后来这X个淫中有12个人不交了,但是剩下的人还非要凑齐D数目的钱,就是问,现在每个人多交多少。唔,很简单哈。 作文:AI physical activities are as important as academics. AA 是说,有个投资公司,在网上做了一个调查说,越来越多的人再网上读书,并且还读Classics books。然后这个公司就说啦,我们要投资出版Classic books的书店。 “Currently more and morebooks are becoming available in electronic form — either free of charge on theInternet or for a very low price per book on CD-ROM.* People who would not paybookstore prices will now have access to whatever book they want from theirhome or work computers. Consequently, literary classics are likely to be readmore widely than ever before: 72 percent of those responding to a recent onlinesurvey said they would read books in electronic form, and 81 percent said theybelieved that reading classic works was important. Given this newly developingmarket, we should invest in E-Classics, a new company that sells electronicversions of literary classics.
阅读,第四篇是说蒸汽机,说18** 年的时候在英国,有人提议说要改进蒸汽机,从而节约煤炭的使用量。但是有个叫J的人说,more energy-efficient 的蒸汽机会使得用的煤更多,因为这种蒸汽机使得用煤变得便宜。。。问题是,1 main idea. 2. 一开始英国人主张什么,我选的是主张改进蒸汽机。3,为什么改良后的蒸汽机反而用的多了?
剩下的有待补充。。。。实在抱歉了。。。现在什么都记不住了。。。 |
