10月22日 北美 680 AWA/Math/RC

兔子一窝

走出考场时，老外监考看到我眉头紧锁地出来，问我知不知道自己成绩，言下之意应该欢心雀跃才是。殊不知中国人好成绩的标准高出老美好多截，只得应付她“I hope I could be better". Anyway, 只能自我安慰运气不佳，以及不再年轻（脑力不济）等等。准备等工作以后，再读一个Part Time的MBA，据说证书和Full Time没什么区别。希望各位战友考得比我好。

AWA 比较幸运，没有遇到难题。
AA: 108－有关Take Heart Fitness Center那篇
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.
Math 除了一题当时不确定外，其它都简单。
n and X is postive number. What's the value for X?
(1)  9^n=100,000*X
(2) 1/10<X<1
CR 感觉考得最不理想，对不少题没有把握。不过有一题是GMD13-40，和大家分享。

    

In response to viral infection, the immune
systems of mice typically produce antibodies that destroy the virus by binding
to proteins on its surface.  Mice
infected with a herpesvirus generally develop keratitis, a degenerative disease
affecting part of the eye.  Since
proteins on the surface of cells in this part of the eye closely resemble those
on the herpesvirus surface, scientists hypothesize that these cases of
keratitis are caused by antibodies to herpesvirus.

    

 Which of the following, if true, gives the
greatest additional support to the scientists’ hypothesis?
 

    

1. Other types of virus have surface proteins that closely
        resemble proteins found in various organs of mice.
2. There are mice that are unable to form antibodies in response
        to herpes infections, and these mice contract herpes at roughly the same
        rate as other mice.
3. Mice that are infected with a herpesvirus but do not develop
        keratitis produce as many antibodies as infected mice that do develop
        keratitis.
4. There are mice that are unable to form antibodies in response
        to herpes infections, and these mice survive these infections without ever
        developing keratitis.
5. Mice that have never been infected with a herpesvirus can
        sometimes develop keratitis.

答案：D

RC 出现了10月RC总结中的第2和第3篇。

谢谢楼主分享！

n and X is postive number. What's the value for X?
(1)  9^n=100,000*X
(2) 1/10<X<1

答案是c，对吗？

不太记得n的限制条件，如果是正数，则应该有很多解，所以选E；如果是正整数，解为n=5, X= 0.59049,所以选C。

楼主很好的分了，我也在北美。学校要求我有600就够了。680已经很牛了。

LZ有没有碰到阅读JJ？

我过两天就考了，阅读可全靠JJ了，呵呵

至少出现了两篇阅读JJ，看来命中率还是蛮高。只是如何利用JJ做对题，看各人的本事了。
