没想到verbal那么烂……平时基本上是38的水平…… 能想起来的题目实在有限，先贡献几道吧…… AWA AA： 70. The following appeared in a memorandum from the president of a company that makes shampoo. “A widely publicized study claims that HR2, a chemical compound in our shampoo, can contribute to hair loss after prolonged use. This study, however, involved only 500 subjects. Furthermore, we have received no complaints from our customers during the past year, and some of our competitors actually use more HR2 per bottle of shampoo than we do. Therefore, we do not need to consider replacing the HR2 in our shampoo with a more expensive alternative.” AI： 131. “We can learn more about a society by observing how its people spend their leisure time than by observing them at work.” Discuss the extent to which you agree or disagree with the opinion stated above. Support your views with reasons and/or examples from your own experience, observations, or reading. 数学： 1。DS：一个正八边形，求a的长度（图1） （1）b=200cm （2）c=根号下20000cm 答案A，因为把正八边形看作园的内接八边形，则已知（1）就想当与知道了直径，又因为一个边对应的圆心角是45度，很容易求出边长 2。如图2，求k的度数 解：设出A和B，如图所示 则2x=50+B 2y=50+A A+B+50=180 （*） 把A，B分别用x，y表示带入（*）式，可得x+y=115，则k=180-（x+y）=65 数字记不太清楚了，方法就是这样。 3。已知一个班，学A的占a%，学B的占b%,学C的占c%,学A且学B的占d%,则只学C而不学A且不学B的人最多占多少？
