本周机警

2003-02-13 16:29:55

本周考的，verbal部分分数低的我都想跳楼。对大家的告诫就是，阅读一定要搞上去，现在verbal前15道肯定会有2篇阅读。如果阅读不好，可想而知成绩会如何？我亏就亏在平时阅读练的少，且不稳定，时好时坏。而且心理承受力不强，考试时文章怎么就读不进脑子。所以对于心理承受力不强的，建议有12分把握再去考。
verbal虽然记得，但由于成绩不好就不误人子弟了。
下面是数学机警。我这会quantity和verbal都没碰到机警。*_*.
(1)square root(cube root(3^48))
(2)which of the following line can go through only one point whose (x,y) x,y are all intergrate number?
(A)y=2x (B)y=1/2(x)+5 (c) y=cube root(3)x
I choose C
(4) DS a company,whose business is to help others to prepare party with 50 to 100 participants,charge how much to such kind of party
i, charge totally 300n-n^2 to the whole party
ii,the company charge $160/person
I choose C
(5) (4/5-16/5)/(4/5+16/5)
(6) a factory produce A and mail product to customors, mail fee is 19.xx. Sale price is 29.xx/each. (具体数计不清了）ask: how many the factory sell its product to customor this time?
i, its total revenue this time is between 280 and 315
ii, its total revenue this time is between 300 and 335
I choose A. (因为根据当时的数据i可得1解，ii可得2解。思路是：280-mail fee=N*price）
(7) a person walk to target place 40miles from here. he use 50miles/hour to finish first 20 miles and use another speed to finish rest. Average speed for whole 40miles is 60miles/hour.Ask:how fast he walk during the last 20 miles
(8) 这体有图是一圆柱切成一半。（就是延圆面，将圆面对半切），问体积？以告知高和直径
就这些，实在想不起来了，不好意思。
在这，我要感谢mba8和G域给我的帮助。
还有妈妈，爸爸，姐姐及男友在我失败后给我的鼓励。我也想告诉所有的朋友，这次的失败是下次成功的基础，其意义有可能远大于成功。希望所有考试的朋友都上750。
