1、如图,一家公司生产3种型号的手机,h,n,p,每部手机卖$80, 求x,使得total profits是total cost的40%; A 5 B 10 C 15 D 20 E 25(选A) types numbers per type cost per telephone h 20 60 n 10 55 p x 50 这个题遇到的是原题,不是变体;
第二篇wine这篇,JJ上的英文原文就是文章的来源,只是经过了些许编辑。比如最后一段提到,对于喝grand wine的Connoisseurs drinker来说, 用橡木塞的玻璃瓶装葡萄酒仍然是最佳选择。 有个题就是问为什么Connoisseurs drinker还是要喝玻璃瓶装的葡萄酒? LZ选的答案是因为carton的包装会让氧气渗入(oxygen permeable,这个单词还是靠才出来的);还有个triky的答案是Connoisseurs drinker will not be convinced by the research(指carton也有它的好处,就是能去除那些不受欢迎的气味)
LZ选的答案是progressive weakening eliminate some of the neuro connections;还有以一个选项比较混淆的是 people long thrived from sleep experience stronger weakening of synapses
阅读暂且就记得这些了
语法补充一道:
African American association's internal audit raised a concern about (the rate of management expenses rising at 5 percent annually). (括号里是划线部分)
Lz 选的答案是 the rate, at which management expenses rise, 5 percent annually. 还有一个答案比较混淆,management expenses, rising at a rate of 5 percent annually.
