2.20 北美，一点感想

sanyejen

考得一般，（栽在CR上了）但申请够用了。

SC:
GWD做过一些题，考前一个星期PREP模考，发现PREP verb题比GWD简单很多。今天真实考试，VERB题感觉跟PREP的很像，比GWD简单。题干很容易理解。划线部分以主谓一致，并行结构，分词修饰为主. 感觉只要好好做完GWD的人，考试时还是很容易看出考点的。

RC:
LOYAL CARD，group interview, LATIN literature .
(有一个关于讲Hispanic的，慌忙中做的已经想不起来了，不好意思）

D.

2. 题干： Pending approval by the united states congress.bla, bla...., the airline said, on January, the growth rate of sth  will be increased..  (整句划线，选项不太记得了）

3. not only, but aslo,

CR:
1. 很多EVALUATION题。（本来这块就差，题干都超长，动不动就搞出五六行，严重走神ING，记不得了，SORRY)

MATH:
遇到7～8道JJ，我数学很差，这次多亏有它也到了50.。在此鞠躬大谢这个月无私奉献汇编JJ的XDJMs.
注意：有一些题有变体：做题时小心。
补充2道：
1，7^(4k+3)×6除以10的remainder是多少？
2，某公司一批货，A的货存量比B的货存量的多20%，同时比C的货存量少20%，问C占总货存量的百分之几？

JJ题：

    

22. 
一个大圆里面切了一个小圆，说小圆的outside diameter is equal to
inside radius of the large circular. And the cross-section area of the large
circular is 49pai, what is the cross-section area of the small circular? （数字不是49PAI, 原体为14PAI)

    

    

18.   
(PS)
        一道路程，跑步的10mile/hr,走路的6mile/hr, 跑步的超过走路的10分钟后到达喷泉，走路的还要多久到？答案： 6又三分之二（即20/3)分钟

56 (DS) p is prime?

A. the only positive factor greater than sqrt(p) is p.

B. the only positive factor less than sqrt(p) is 1.
        

    

    

61. 
.hexagon 的each edge is 80, what is the
diagonal? (考试时：80改为20）

    

268. 1. 一个衣柜里有a, b, c三种衣服，c的数量>7，这三种衣服之比是9：4：5，问题是这个衣柜里共有多少衣服

    

（1）衣服总数less than 30

    

 (2)  a 和b一共是26

    

（D)

267. PS：一个苹果派要三杯剥皮、去核的苹果。剥皮、去核的苹果会比原来轻1/5。两杯剥皮、去核的苹果重1pound。1pound苹果值$1。问做p个pie要多少钱。15P/8

        

233. 40个人，60%的人参加A 30%的人参加B，
            问既a又b的多少，

        

1）一共35（不确定，但不是40）个人参加了ab，改为：只参加B而没有参加A的人数是4人。

        

2）有5个没参加AB

1. All Y chromosomes in existence today are descended from a single ancestor’s who is thought to have lived about 140,000 years ago.

A.      a single ancestor’s who is thought to have lived

B.      a single ancestor’s who was thought to live

C.      a single ancestor whom it is thought had lived

D.      the Y chromosome of a single ancestor who is thought to have lived

Answer is D

so u got over 700?

. 一个衣柜里有a, b, c三种衣服，c的数量>7，这三种衣服之比是9：4：5，问题是这个衣柜里共有多少衣服

（1）衣服总数less than 30

 (2)  a 和b一共是26

有问题，我不太明白。选项1，在这里明明是个假命题。就算加到题设里面变成assumption, 也不能推出来衣柜里衣服的确定数目啊。假名题与假命题推不出真命题的啊。

首先衣服应当是9：4：5的整数倍，（非9，4，5的一倍），衣服不可能比30少啊。

cathyzq

A肯定是对的，9:4:5,可以看作 ，9K:4K:5K,又告诉条件C>7，则5的倍数1，不符合，2则为10，则假设K为2，则A=18，B=8，C=10，则小于总和30的限定条件，则，A可以求出，如果将K=3时，则无法求出。对了想问一下质数那个题目，我觉得是D，可否帮我更正一下我的想法，我还是没有完全想通，谢谢

hexiaoyanyan

A=18，B=8，C=10，则小于总和30? 18+8+10=36 怎么能是小于30呢？A应该不对吧

excellor

请问这道题“7^(4k+3)×6除以10的remainder是多少？” 怎么做啊？

以下是引用sdtifa在2009-2-21 5:42:00的发言：

1. All Y chromosomes in existence today are descended from a single ancestor’s who is thought to have lived about 140,000 years ago.

A.      a single ancestor’s who is thought to have lived

B.      a single ancestor’s who was thought to live

C.      a single ancestor whom it is thought had lived

D.      the Y chromosome of a single ancestor who is thought to have lived

E.       the Y chromosome of a single ancestor whom it was thought had lived

Answer is D?

remainder是8，可以用代数法，无论K等于多少，都是8

268是不是应该选B啊～
