那题链接的解释很牵强。。。我觉得我的解释是最合理的，如果veterinarian是兽医的意思能被准确的翻译的话。。。呵呵

还是队长强啊！！

感谢顾风 回答数学

另外，我想知道你数学是怎么找到连接的？

tt 的题和xy,gwd编号对应关系是什么？

我没有找，数学只是做tt，错了搞不懂的我就直接提问了。。。偷了下懒。。。不好意思。

5楼的回答很到位啊，D是攻击了CXC得有毒性，是他因削弱。MM有什么问题呢？

btw，mm是怎么做lsat的呢？我曾经尝试去做lsat，但是发现讨论连接很少阿，只能发贴问。觉得这样效率会很低的，后来就放弃了。

看了队长的解释，我现在更明白了，可以睡个安稳觉了。

要不是为了考个750＋，我才懒得做LSAT。

一些比较难的题的讨论还是挺多的。我发现大部分没讨论的题都不难，像我这样的菜鸟都能作对。

有些郁闷难题，我就把他们当脑筋急转弯做，杀一杀多余的脑细胞，练练思维。

顾风

MM多余的脑细胞给我吧。。。

那我为什么直接问就被警告了呢？人品？赫赫

另外，这样不好啊，为什么我给的解释你们都懒得评价对错呢？

这叫我相当郁闷，我都不知道到底是理解对了，还是理解错了

顾风

一般这种情况属于你的解释是对的。。。

如果是错的或者有争议的，就会有评论。。。

我觉得这道题是充分和必要互相颠倒了

essensial 是必要

if 充分

说无关好像不太对

谢谢大家这么热心的回答，这道题我没有疑问，只是go so far as to这个短语

不明白确切的含义，在longman上找到了解释，和顾风说的差不多。

6
go so far/as far as to do something
(spoken) to do or say something extreme
->The government went so far as to try to arrest opposition leaders.

->I wouldn't go so far as to say that we agreed on the subject.

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?

顾风

正是因为太精确，所以错了。

因为600个人是抽样调查，必然涉及到如标准差，方差的概念。通过这个调查，我们不能得到你这样精确的结论，必须要通过多组实验，然后说reduce the average incidence of serious cases of flu by 25 percent。

don't you think so?

顾风

另外 massive是相对于standard的描述，我个人觉得没有问题。
