数学碰到大约10道寂静，做得挺顺的。印象比较深的是一道DS题： M=P[0.005(1.005)n]/(1.005n-1) 某人贷款P元，利率为6%，按月计复利，每个月付M，分n个月付完，M、P、n满足上述等式关系，问M>50？ （1） P=10000 （2） n=48 我根据题干条件自己写了个P、M、n之间的方程就是一个M的等式再与题目给的那个等式联立，结果感觉很复杂，与（1）（2）两个条件没什么关系，其实我觉得如果按照正常的思维来的话n和M 的值都是可以求的，我搞了半天，后来决定只用题目给的那个等式，大概估计了一下，选择了D，不知道错了没有。 其他的题目还好不是很难，所以都忘了，记得的都是寂静里已经有的。 真不好意思，语文想不起来了，慢点想起来再写……
对了，还有AA：是campus housing occupancy rates fall 那道： 38. The following appeared in the editorial section of a campus newspaper.“Because occupancy rates for campus housing fell during the last academic year, so did housing revenues. To solve the problem, campus housing officials should reduce the number of available housing units, thereby increasing the occupancy rates. Also, to keep students from choosing to live off-campus, housing officials should lower the rents, thereby increasing demand.” Discuss how well reasoned... etc. AI： 81. “No one can possibly achieve any real and lasting success or ‘get rich’ in business by conforming to conventional practices or ways of thinking.”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.
