[转帖]325,北美,些许JJ

robert

终于考完了,M-51,V没上20,总分不到600,

唉....这样的成绩的也就对我这样的人有点儿用

反正够申请我想去的学校了,不重考了.

废话少说,来点正经有用的东西.


作文:

1.AA:

一种杂志宣传一种健身器,问要不要给新的健身房装这种健身器

2.AI:

\\"We can tell the ideas of a nation by its advertisement\\"


数学:

JJ狂多,不记得有几道,边写边算吧:

1.JJ-119. 直线a,b过（16/5, 12/5）,问直线a的斜率 a）两个直线斜率积为-1, b） b直线过原

但是数字好象不太一样,道理一样就行.选C

2.JJ-121. compound interest is 0.08,问存x美金5年，钱是多少，我选x.(1.08)5次方
这道数字都没变

3.JJ-125. 7！/一个整数x＝一个非整数，请问这个x最小为多少 答案有7，9，11，13，15 我选了11

这是我的最后一题.

4.JJ-175，what percent of 10 equal 10percent of 1.
a , 0.01% b, 0.1% c,1% d, 10% e, 100%

我选的是E

5.JJ-187. 2个箱子，一个里有20个purple球，30个yellow，另一个里是15个purple, 35 yellow 随机从两个箱子里拿一个，是purple的概率

记得答案好象是9/20

6.JJ-194.ABCD四个group,分别有10, 10, 10, 20人，从abc中每个组选1人，d中选2人组成一个研究小组，共有多少种？
这是我的第二题,当时有点犯晕,拼命把四种情况加起来,怎么加都找不到答案,后来发现应该是相乘,气吐血,答案是190,000,有一个迷惑答案是19,000,小心点就行.

7.JJ-197. s>t p>r r>s q>p, 问中数

好象字母有点不同,我的题里有个U,反正很简单,不必担心

8.JJ-202. 100个冬冬一个机器完成要5小时，加一个新的要2 小时，求新的每小时做几个？

答案是30, 40+2x=100=>x=30

9.JJ-226 what is the value of (2^p)*(4^-q)?
(a) p=2q b) p=q

我选A

10.JJ-293. 两个人,从A称到B城.第一个人用了四个小时,速度在25和45之间.第二个人用了两个小时,速度在45和60之间(速度的数值不是很准确.)问两个城市之间的距离大约是多少.

我选的是115,可以分别从两个人的速度算出两个范围,可以知道100<路程<120

11.JJ-298. At a fruit stand yesterday, the price of each apple was $0.10 more than the price of each orange. What was the total revenue from the sale of oranges at the fruit stand yesterday.
(1)The number of oranges sold at the fruit stang yesterday was 5 more than the number of apples.
(2)The total revenue from the sale of appples at the fruit stangd yesterday was $15.00
我也选的是E,虽然JJ里有,但这道题我没认真算过,今天仔细算了

好半天,好象应该是选E,不知道JJ讨论里有没有结果.

12.JJ-314、问x的十位数为3，他的个位数大于4吗？1）the digit of the x is greater than the digit of the 2x 2) the ten digit of 2x is greater 7 , my answer ：d
我也是选了D

13.JJ-355.DS:An positive integer, what is the remainder of this integer divided by 10

(1) can be divided by 5 and the reminder is 2

(2) can be divided by 2 and the reminder is 1

Ans: C

可以算出只能是7

14.2004年3月JJ,

127.ps.abcd正方形, 边长为1,DE=1, AE=CE, 求ADE面积(如下图)
此主题相关图片如下：
橙子评价:2^(1/2)/4,延长ED与AC交于0(如下图)因为AE=CE->AO=CO->0是对角线的交点->角ADO=45度->角ADE=135度->SADE=(1/2)*AD*DE*SIN135我的做法是用三角形AOE的面积减掉三角形AOD的面积,O为正方形对角线AC的中点,







以下的题就不知道是不是老JJ了,


15.两个人各有一些COIN,求TOTAL

1)甲的个数是乙的4倍. 2)几倍某人的钱在一个范围里

我选的C,因为好象是通过2)可以算出那人的钱的范围,

又根据1)缩小了范围,可以确定只有一个整数解.

这题记得不清楚,对不起大家.

16.给了摄氏度和华氏度的公式,问华氏度有没有低于50(不确定)

度:

1)摄氏度低于-5度, 2)摄氏度高于-2度

很容易算

其他的一时没想起来,等想起来再来补充吧.

总的感觉是,平时觉得难的JJ都没考,题目比想象中容易.

Verbal部分,

我的水平低,遇到的JJ有限,而且时间仓促,看题都匆忙,更别说

记了,有一点印象的是:

第一题:SC

GWD-3-Q29:

Unlike the conviction held by many of her colleagues that genes were relatively simple and static, Barbara McClintock adhered to her own more complicated ideas about how genes might operate, and in 1983, at the age of 81, was awarded a Nobel Prize for her discovery that the genes in corn are capable of moving from one chromosomal site to another.






Unlike the conviction held by many of her colleagues that genes were relatively simple and static

Although many of her colleagues were of the conviction of genes being relatively simple and static

Contrary to many of her colleagues being convinced that genes were relatively simple and static

Even though many of her colleagues were convinced that genes were relatively simple and static

Even with many of her colleagues convinced of genes being relatively simple and static [D]*

1.GWD1-Q35 to Q37供应商的题

2.爱尔兰妇女的问题

另两篇是没啥印象了


逻辑:

做飞机的公司宣布要裁员,尽有一个航空公司新订了一批飞机,够这家公司做两年的了,这公司还是要裁,问支持:

好象是那家航空公司订货的同时又取消了一批原来的订单,而且原来的比新订的还贵.


其他的也不记得了,真是不好意思......


顺便问一下,俺这样的,要用多久准备托福啊?目标550
