现在才发JJ,不好意思哈! AI: the best teachers are those who expect students to challenge popular ideas rather than accept them. AA: the more efficiency employees are, the more profitable a firm is. we should invest in the information technology hardware and software to improve the efficiency of the employees. The strategy that enhance the information technology will help us to maximize the profits.(貌似记得有点不全,大家见谅) Math:碰到了几道JJ。 1.a1,a2,a3,a4,a5是一个数列中的,数列是a(n)=a(n-1)*q。q is positive,问q=? (1)a1=1 (2)a5=1/16 2.537的20次方,问展开后个位是多少? 3. In the store of a car dealer, less than 10 cars are equiped with fog light, and 40% of the cars that equiped with fog light have **window, Is the dealer has more car with fog light than those with **window? (1)80% cars have fog light and window (2)52 cars have fog light or window or both(红色是我补充的,我选的A) 4.一个数列64,66,67,……, Xn=8+Xn-3, n>4,问以下哪个选项可能是数列中Xn的值? 5.半圆里面套一个大正方形,旁边再套一个小正方形,问小正方形面积,圆半径是2根号5 补充下JJ中没有的,尽量回忆,大家做题的时候还是要看清楚题! 1.10个小孩捐了28件衣服,每个人都捐了,range为2,问以下哪几个可能是捐了3件衣服的小孩人数?有0,5,9三个,我选的0和9可以 2.有道DS题比较tricky,题目记不太清了,反正给了你一个S percent,一个t percent, 求t percent。两个条件可以列出两个方程,但算出来后是等价方程,所以选E。 3.给了个数轴,上面标了0,1,说y is left of 0, x is left of y, 问以下哪几个正确?第一个说xy is left of 0, 第二个说xy is right of x, 第三个说xy is right of y, 选二三。 4. we call a number perfect square that is square of a interger. n is a perfect square, which one is the least perfect square that is larger than n? 选项记不太清了,大家看哪个可以化成整数的平方就行(利用根号n是整数就行) 数学跟prep差不多,大家细心点就可以! verbal: 这部分做的一般,语法感觉和prep很接近,不是单纯的平行啥的,蛮考逻辑的! RC:第一篇挺短的,两段,讲company director influence the choose of CEO,是选outsider还是insider。比较简单,也没什么生词。题目有个主题题,其他定位就行。 第二篇是热带雨林多样性那篇,JJ已经很清楚了 第三篇很长,三段,而且第三段长度跟一二段加起来差不多。讲supernova的。第一段说explosion之后的supernova会radiation,evolve越来slow,寿命不长,然后不radiation了。第二段说不是所有的都这样,有种P(记不清了)它寿命比正常的长。说它是从supernova发展来的,也会经历evolve越来slow,寿命不长,然后不radiation的阶段,但后来它会找到一个star来给予它物质,然后evolve quickly,and radiation,第三段就是解释,说科学家发现了四个现象可以证实有neutron star为它提供materials.这篇主要是有好多名词,大家分清楚就可以了,然后做题的时候定位,题目有这种star与normal star的不同,其他记不太清了,不好意思哈! CR:记忆不行,怕误导大家! 以后想起来了再补,祝大家都取得好成绩哈!
