I.AWA:

AI: 92. (黄金80题)

“Government should establish regulations to reduce or eliminate any suspected health hazards in the environment, even when the scientific studies of these health hazards are incomplete or contradictory.”

Discuss the extent to which you agree or disagree with the opinion stated above. Support your position with reasons and/or examples from your own experience, observations, or reading.

AA: 34. (黄金80题)

The following appeared as part of a plan proposed by an executive of the Easy Credit Company to the president.

“The Easy Credit Company would gain an advantage over competing credit card services if we were to donate a portion of the proceeds from the use of our cards to a well-known environmental organization in exchange for the use of its symbol or logo on our card. Since a recent poll shows that a large percentage of the public is concerned about environmental issues, this policy would attract new customers, increase use among existing customers, and enable us to charge interest rates that are higher than the lowest ones available.

II. Math

1.3X=5y, x is what percent of Y? (first question)

2.What’s the ratio for C12-6 to C12-5 (third question)

3.JJ23、 一共有12个老师,会法语的6个,剩下的会德语的或者西班牙语。选4个人,至少有1个会法语的组合多少?

4.JJ35、斜率. 问一条线斜率是否等于零? A: 经过点(0,2); B. 此线平行X 轴; I 选 B;

5. 48、2004年第29. ds.x^2 +2qx+ r =0 , ask for the numbers of intersection with X-axis.(重复两次) A: q^2>r B: r^2>q 橙子评价:选A

6. 77、PS;A.B.C三个机器,produce at the same constant rate,两台机器一起工作一个星期生产M个东西用的时间比三台机器一起工作一个星期生产M个东西用的时间多两个小时(不记得单位了),好象是求M,反正记得我当时列的方程就是设速度为a,1/(2a)=1/(3a)+2,求出了a以后就可以求总量了

7. JJ283、K>=1 KX>8-KY?(更正:K的条件不对,我又回忆起来了,原题是说K为不为0的整数)

1) K(X+Y)=10

2)X=5 Y=10(具体数字不确定,但确实是给X和Y的具体数字)

这题看似容易,怕有陷阱,想来想去最后选了个D (I choose D also)

8. 2^(m+1)*3^(z-1)=72, what is for 2^(3-m)*3^(z-2), anyway, answer is 2*3=6,

(the last question for math-50, the easy last question let me nearly cancel

the report)

III.

Sc: one from GWD, (美国劳工部长)的个人强大的影响对罗斯福的作用,注意主语,(The first question in verbal section)不难

Cr: one from Gwd, BF question, sorry can’t remember the concrete question.

RC:

1篇: 欧洲国家建立EU的目的就是为了提高企业的竞争力, 和欧美竞争. 传统观点认为大幅度的减少贸易阻碍, 可以促进企业的合并, 从而产生规模经济效益, 降低成本.但是, 作者认为这样一来, 小企业基本就会大量消亡了. 此外, EU的边境开放对不同工业影响不同.对于某些工业, 如计算机和航空, 它们的规模化已经很大了, 而且也一直在国际合作, 因此EU开放边境的意义不大.而对于另外一些工业, 如制衣业, 大规模生产也不能减少成本.

第3篇:1。池塘生态环境与蝌蚪那一篇,前人机经很详细。

感谢古镯,蓝夕叶子,LES, 感谢前人JJ. 只是提醒大家考前别忽视做英文数学题,否则,考场上有些反应不过来的感觉。Good luck on the coming exam!
