42. 以下哪个数可以不能用有穷小数表示(terminated decimal ?),答案分别是2,3,5各次方互相除,我选分母中有3的选项,因为只要分母中有3或3的几次方,肯定是无限循环小数,而2和5都可以有限除尽
虽然没有给出答案,但思路是正确的。
66)超简单的正六边形中的一个正三角形,(其实就是六边形均分成6个等边三角形,)再把该三角形位于正六边形中心的顶点箱底边做垂线,那个顶角就变成30度了,答案就是30度。
67) 矩形的周长28, 可否求面积?
1. 两对角距离给出
2. 一条边长给出 不大确定了SORRY
74) xy<1?
1) x+y>1
2) x^2+y^2=1
想到8个好象没人发过的:
1. x, y, z are numbers on the number line. Is x < y < z ?
a) |y-x| + |y-z| = |z-x|
b) x<z
2. 10 apples, 2 of them weighs 4 ounces each, 3 of them weighs 5 ounces each, and 5 of them wights 6 ounces each, what is the median of the weights of the 10 apples in ounces?
3. the 1st item is 1, the 2nd is 2, from the 3rd item onwards, the item is the obtained by subtracting the item before the item before it from the item before it (我实在想不起来原题是怎么写的了。但就是这个意思。). for instance, the 3rd item is 2-1=1. How many possible values are there for the sum of the first n items?
4. A set {1,2,3,4,5,6}. select 2 numbers from the set, is the sum of the 2 numbers divisible by 4?
a) the larger number selected is 3 times the smaller one
b) both selected numbers are odd numbers
5. telecom charges $0.02 (may not be this value) for each minute of phone call made for the first 300 minutes, and $0.05 for each minute of phone calls exceeding the first 300 minutes. How many minutes of phone call is Henry (just a name) charged for his last month phone bill?

6. n is positive integer. 9^n = 10,000 * x. What is the value of x?

b) 1/10 < x < 1
7. 碰到两个worker题。一个是这样的:machine A can produce x products in 1 hour, machine B can produce x products in 3 hours. If machine A and B work together to produce x products, what is the ratio of the products that the faster machine produce? (选项里给的是分数)
8. 又想到一个条件概率题:a company has 255 employees. If one employee is randomly selected, is the probability that the employee is a woman and has a college degree less than 1/2?
a) 135 employees do not (原题就在not下划了道线) have colleage degree

52. The following editorial appeared in the Elm City paper.
“The construction last year of a shopping mall in downtown Oak City was a mistake. Since the mall has opened, a number of local businesses have closed, and the downtown area suffers from an acute parking shortage, and arrests for crime and vagrancy have increased in the nearby Oak City Park. Elm City should pay attention to the example of the Oak City mall and deny the application to build a shopping mall in Elm City.”

34. “All citizens should be required to perform a specified amount of public service. Such service would benefit not only the country as a whole but also the individual participants.”
Verbal 做得没有感觉,估计能错一半。就不说了。。(但觉得4个RC还都读懂了的。。sigh....)
学理科的对GMAT的数学可能没在太大的问题。Verbal要着重复习。我考完了才发现自己对Verbal掌握得太不好了,尤其是CR和RC。同时,pace,很重要。想了一段时间之后还想不出的题,一定要下决心跳过去(当然是选一个答案再跳过去)。因为既然已经想了这么长时间都不能确定答案,很可能再给你再多的时间你也想不出正确答案。不跳过去的话,你占用了时间,做后面的题的时间就短了。这是非常非常非常不划算的。我犯下了这个很大的错误,最后3道题都没能仔细看,还都是长题,越急呢越看不懂选项是什么意思,分就白白地丢了。朋友们,请不要犯我这样的错误。。
谢谢!
