以下是引用lexie在2006-7-11 20:37:00的发言:

我做这道题的时候还真的运算了一番 觉得C项的数据没有错 你看了顾风GG的解释么? 偶觉得他说得在理

C的意思是说 超过日常标准的剂量5倍的Vc剂量 (实际相当于250mg的六倍,文章用的exceed BY 500 percent, =250mg*6=1500mg)能够减少25%重感冒的发病率 用250mg剂量的Vc的发病率是34%, 那么减少25% 为9% 刚好跟文中的叙述相吻合 但是呢:请注意了文章用的是fewer than 9%而不是  exactly equal to 9%...所以这道题 真的很花时间 毕竟要做一下小运算才能把C项排除

 后来经过Gufeng gg的提醒 觉得用模糊的词比较好 massive is preferable.

再次谢谢gufeng gg.


我问你啊,exceed by 500 percent 你用250*6=1500

                  decrease by 25 percent 你 怎么能用 34%-9% 呢??? 不都是用了介词by 了吗?怎么一个乘,另一个减了呢?

不知道你理解我想说什么了没?

已知  r/ (b+w) >w/(b+r)

 

 

r/b+w <      (r+r)/b+w+r

w/b+r  <      (w+w)/b+w+r

能不能得出  r/b+w+r   > w/b+w+r   ???

Allen哥哥不要生气 偶如果没有说清楚 偶apologize

not to worry...

decrease by是减少了多少 如果用介词to是减少到多少 exceed by 超过了的量 超过了500% 就是比原来多5倍 超出量的计算如下:1500-250=1250 1250/250=5=500% 不知道解释清楚了没有?

这里500%跟 25%的基数不一样的 前者对应的是standard recommanded daily allowance

后者的基数是 incidence of serious cases of flu...

其他有好心人愿意帮忙解释一下么? 其实C不是正确答案 用gufeng  gg的模糊逻辑做题 绝对是正路 偶只是想分析一下错误选项为什么错了 没有别的意思 did my post sound offending to you, Allen? I was wondering....

以下是引用lexie在2006-7-11 14:34:00的发言:

14.A nutritionist studying the effects of massive doses of vitamin C found that of a group of 600 people who regularly took 1,500 mg of vitamin C daily for a year, fewer than 9 percent suffered serious cases of flu; of a group of 600 people who took 250 mg of vitamin C (the standard recommended daily allowance) daily for a year, 34 percent suffered at least one serious case of flu; and of a group of 600 people who took no vitamin C for a year (other than that found in the foods in a balanced diet), 32 percent suffered at least one serious case of flu.

Which of the following hypotheses is best supported by the evidence above?

(A) The effectiveness of vitamin C in preventing serious cases of flu increases in direct proportion to the amount of vitamin C taken.

(B) Vitamin C is helpful in preventing disease.

(C) Doses of vitamin C that exceed the standard recommended daily allowance by 500 percent will reduce the incidence of serious cases of flu by 25 percent.

(D) Massive doses of vitamin C can help to prevent serious case of flu.D

(E) A balanced diet contains less than 250 mg of vitamin C.

Hi guys,

I need your help. Why not choose C ? As far as I am concerned, C is more precise than D, because C gave more detailed numbers than D did. As to D, it just gave a very abstract concept " Massive"...but I was wondering...how massive is massive?  Any comments or thoughts on this problem?


我想C是不对的。C过于绝对了。读起来的意思好像指 Vitamin C的量必须到达500倍,才能达到防止重感冒的作用。事实上,或许200, 300,400倍的量就能防止重感冒了呢 ?

但是我们可以肯定的从题目给出的事实说:“大量“的 Vitamin C能防止重感冒。这个hypothesis放回题目中也可以被验证的,因为1500mg/daily大大超出正常推荐量的。所以D的假设是最合适的。

赶紧进入状态:lexie,(C)选项中过于强调只有超额摄取Vitamin C 才能有效prevent flu,这是确实是一个支持选项。可题目需要找一个起支持作用的假设,所以觉得(D)更好些。当拿不准注意时,可以:将选项取非,看其是否削弱。

不是NN,随便说下

请教大家啊

复习了三个多月了,还不用工作,可是现在做模考感觉还那么不好,有时候看到OG就想扔了,哎,你们大家有没有真的很不想坚持的时候呢?

大家有没有什么好办法?被GMAT折磨得很痛苦的时候,你们怎么调整的?真的我发现状态不好的时候,做题很糟糕的.还有GMAT到底是看最高分,还是参考平均分啊?

ETS 蒸题, 大家赶快做!晚上公布答案

The members in Aug. Echelon r mainly discussing problems of CR here. It was said by some NNs that CR r just 4 relaxition, so it will be quite reasonable to induce that members in Aug. echelon will turn out to emerge less NNs than echelons of other months. 

 

Which of following will substantially weaken the argument above?

a. nns' suggestion is sometimes not typical

b.the Cr questions raised here r typically convoluted even to super NN

c.the real nn never raises CR questions

d.there r perhaps more members in Aug. echelon than those in other echelons

e. members in Aug. echelons r stronger in CR than those of other echelons
