作文：  志愿者救护车和商业救护车那道

            学校应该多花时间教科学技术还是艺术人文。

CR：

In polluted environments, dolphins gradually accumulated toxins in their body fat, and the larger the dolphin the more accumulated toxin it can tolerate.  Nearly 80 percent of the toxins a female dolphin has accumulated pass into the fat-rich milk her nursing calf ingests.  Therefore, the unusually high mortality rate among dolphin calves in the industrially contaminated waters along Florida’s Gulf
                Coast is probably the result of their being poisoned by their mother’s milk.

Which of the following, if true, most strengthens the argument?

1. The survival rate of firstborn dolphin calves in the area along Florida’s Gulf
                       Coast is highest for those whose mothers were killed before they were weaned.

2. The rate at which adult dolphins living in the waters along Florida’s Gulf
                       Coast accumulate toxins is no higher than that of adult dolphins in comparably polluted waters elsewhere.

3. Among dolphin calves born in the area along Florida’s Gulf
                       Coast, the mortality rate is highest among those with living siblings.

4. As dolphins age, they accumulate toxins from the environment more slowly than when they were young.

5. Dolphins, like other marine mammals, have a higher proportion of body fat than do most land mammals.

选A，没妈的海豚成活率高

专业杂志期刊很贵，学校图书馆要买的话太贵，所以就建议本学校的专家把他们原先发表在期刊上的论文放在网上供免费浏览．这样可以解决学校图书馆钱不够的问题．　问假设　答案确实都很绕，我碰道这个，但原文比这复杂（是原作者没记清，还有有变化，不知道）我的是：专家出版作品在专业杂志期刊，得到financial benefit。学校图书馆要买的话太贵，所以就建议本学校的专家把他们原先发表在期刊上的论文放在网上供免费浏览．这样可以解决学校图书馆钱不够的问题题目   我选的是，专家不会因为把他们原先发表在期刊上的论文放在网上供免费浏览而得不到financial benefit。

RC： 建筑师和客户的冲突 美国究竟是债务国还是债权国 陨石的成分假说（这篇短，但狠难，建议事先查查相关单词。否则狠影响答题，光看jj基本不行）还一个想死我了，想不起来了。应该不是jj。

math： jj的内容基本涵盖了，我碰到大约5个吧。也许更多，我没记了，我记的多是计算量大，剩下的30道自己搞的。 没满分，有点遗憾。

补充一句，我觉得gmat阅读的题库相对小，逻辑和语法太大了，所以光依赖jj搞cr和sc很不够。 一定通过阅读来提高！！

sofa...

看来这道专业杂志期刊的CR题干还是很难的嘛,三个人给了三个不同题干.

教授通过在这些高级期刊上发表文章赢得声誉,而期刊也通过这些文章赢得自己的声誉.但学校图书馆为了支持教授的研究必须购买这些昂贵的期刊,而这使得期刊的价格更加昂贵,形成了恶性循环, 所以就建议本学校的专家把他们原先发表在期刊上的论文放在网上供免费浏览．(这样既可以解决学校图书馆钱不够的问题，又能为学校和教授赢得生育)。
            问假设 

 可爱橙子给的版本,括号中的内容是我认为原题干所要达到的目标,同时她给的选项:

有了可以免费浏览的论文以后,图书馆就不必购买这些期刊了.还有几个答案是:1.教授会上网浏览这些文章.2.有了这么免费论文后,这些期刊就不再出版了.3.在网上发表可以给教授提供新的赢得声誉的方式. 

个人倾向于答案3

这道题很复杂，看起来不同的jj题干和答案都有变..

谢谢楼主分享！
