昨天数学答得比较顺手，提前15分钟就做完了，但是作语文一直无法集中精神，之前最有把握的逻辑题居然没有一道题读明白，好可怕的说，读了两三遍后全靠感觉蒙选项，整个状态完全被搞砸了，全凭数学来撑上七百。考完一直觉得有点遗憾，但是还是开始准备申请下一步吧。

AWA

AA NO9: on average, middle-aged consumers devate 39 percent of their retail expenditure to department store products and services, .... these stroes should begine to replace some of those products intended to attract the younger consumer with products intended to attract the middle-aged consumer.

AI NO13: responsibility for preserving the natural environment ultimately belongs to each individual person, not to government.

(1)    f(-1)=5

(2)    pqr<0

2.       in 1984 one dollar could buy 252 Japanese Yen, in 1995 one dollar could buy 89 Japanese Yen, how much more dollar need to buy 10000 Japanese Yen in 1995 than in 1984?

3.       k and m are consecutive even number, does k > m?

(1)    k+2 and m-2 are non-consecutive even number

(2)    k-1 and m+3 are consecutive odd number

4.       Set S are all integers of multiple of 2, set T are all integers of multiple of 4, does the integer m have the property of in set S but not in set T?

(1)    m is an even number

(2)    m/2 is an odd number

5.       一个长方形的屋子地面有两块圆形污渍，面积均为pie/100，污渍圆心离最近的墙的距离大于3，问一个圆形地毯是否可以遮盖住两块污渍？

(1)    地毯的面积是9pie

(2)    两块污渍的圆心相距4

6.       这道题我看到已经有人写过了，就是一个圆分成八份，弧对应的分别是10、20、30、40、50、60、70、80，问八个点连接起来的八边形最大角度数？

7.       x and y are integers, 8^x < 4^(y+1)?

(1)    x < y+1

(2)    3x < 2y+2

8.       k is an integer, what is the remainder of (k^2)/8?

(1)    k divided by 2, the remainder is 1

(2)    k divided by 3, the remainder is 2

9. 330 is the factor of the product of first n consecutive positive integers, what is the least possible n?

实在不好意思，语文完全记不起来任何东西，大家见谅。

 简单说说我的答案吧

1.a  2. 比较简单，选项也都是近似数

3.d   4.b    5.c    6. 165   7.b   8. a   9. 11

 5.我的理解离墙距离这个条件只是为了考虑地毯放得下

11.这道题之前条件说的有遗漏，十分抱歉，我记得我读完题的理解是从1开始正整数之和，

可能自己在表达上给大家造成了困扰。

2.       in 1984 one dollar could buy 252 Japanese Yen, in 1995 one dollar could buy 89 Japanese Yen, how much more dollar need to buy 10000 Japanese Yen in 1995 than in 1984?

(10000/89)-(10000/252)=73(约等于)

3.       k and m are consecutive even number, does k > m?

(1)    k+2 and m-2 are non-consecutive even number

(2)    k-1 and m+3 are consecutive odd number

D

4.       Set S are all integers of multiple of 2, set T are all integers of multiple of 4, does the integer m have the property of in set T but not in set S?

(1)    m is an even number

(2)    m/2 is an odd number

估计LZ有可能记错，应该是问在S却不在T吧？！如果是这样就B，如果没记错就E吧。。。

5.       一个长方形的屋子地面有两块圆形污渍，面积均为pie/100，污渍圆心离最近的墙的距离大于3，问一个圆形地毯是否可以遮盖住两块污渍？

(1)    地毯的面积是9pie

(2)    两块污渍的圆心相距4

C

（想请教一下“污渍圆心离最近的墙的距离大于3”这个条件是不是用来保证那两个污渍不会贴着墙，不能被遮盖的可能啊？谢谢）

6.       这道题我看到已经有人写过了，就是一个圆分成八份，弧对应的分别是10、20、30、40、50、60、70、80，问八个点连接起来的八边形最大角度数？

165

7.       x and y are integers, 8^x < 4^(y+1)?

(1)    x < y+1

(2)    3x < 2y+2

B

8.       k is an integer, what is the remainder of (k^2)/8?

(1)    k divided by 2, the remainder is 1

(2)    k divided by 3, the remainder is 2

A

9. 330 is the factor of the product of n consecutive positive integers, what is the least possible n?

11

请指教！！

坐沙发啦！亲爱的，我们该开始申请啦~

xj，你的数学回忆的好清楚啊！难怪满分！！！

其实是语文太烂了，一片空白，只有回忆数学了。

我现在开始愁ps了。

我觉得第九题应该是7.

5*6*11=330 => 5,6,7,8,9,10,11 共7个连续整数.

请讨论.

我怎么觉得应该是3呀：

9 10 11这3个连续的整数的乘积，就有一个因子是330了呀。

请指教！

第4题“如果没记错的”答案应该是D吧。因为1、2都可以推出the integer m doesn't have the property of in set T but not in set S
