奇奇狗狗 原始回忆

紫苏月白

今天考完，实在杯具，就把一些记得的题目分享一下吧~

坐稳：AA是那个要不要approve新的ice cream outlet的Loan，我记得是提到Forgid Cow和Kool Kone的那个~
AI是employer要不要禁止employee的unhealthy behaviors的。

输血：记得不是很清了，印象就是一大堆计算，还有各种估算，算的吐血...

噢噢，记起几道，有一道是给了个油罐车的图（圆柱体）说油罐车空罐重50kg，每立方米的油重xkg，然后给出了diameter和油罐的宽度（就是相当于圆柱的高），然后让你算满油的时候油罐车重大约多少...本来不难的，不过我不认识那个diameter的意思啊！！！所以悲了。。。

还有一个club的member参加gym 或者swimming的人数是90%，然后好像是问只参加swimming的人数是百分之多少。。。是DS题，选项记得不是很清了，但很确定答案是E，就是两个statement都不足以推出。因为statement1和statement2是等价的，都不够条件。

还有。。。题中要判断是否x>y，DS题，选项一是xz>yz，选项二是xyz=0。貌似题是这样的，记不太清了。。。

要求2^51的因子与另一个数的因子一样。具体哪个数我没记住，不过方法就是x^a X y^b X z^c的因子数就是(a+1)(b+1)(c+1)。

月读：有一篇是biofuel的，是讲现在可以使各种植物转化成biofuel，然后转化过程中有一些附加产物可以做成助燃剂（就是和石油一起提炼出来的那种= =）有题此处；这篇阅读一共三段，第一段介绍biofuel，第二段讲biofuel的优点（用处多，可吸收CO2，各种各种）有道考第三段的作用的。这篇印象最清楚，是最后一篇阅读，当时还happy终于有一篇看的懂了，现在看来是等级低阿Orz...这篇月读的植物名词我实在没记住，keyword就是这个biofuel。= =杯具的记忆力= =

噢噢，终于又想起一篇，一屏半的天文阅读文，秒杀我。。。原谅我，那个X星的名称没记住。好像是讲一种星星因为发光需要燃烧，燃烧自己内部的物质，所以会越变越小，so 现在宇宙中的X星都是很young的。但有一种同类型的“变种星”old，因为它所在的环境里一般周围会有另一种星星，“变种星”burn的时候可以用旁边星星的物质什么的。。。然后又说这种看法得到证实什么的。。。blablablabla

啊啊啊！！又回忆到了一篇啦~~是US manufacturer为调查他们的销量（差不多是这个目的）改用了一种新的online的问卷形式，因为原来的现场问卷很受retailer的抵制，而且还会影响真实存货什么的。。。文章主要介绍了这种新形势的优点。我印象中好像考题主要出在后两段，就是manufacturer的改变过程和新方法的优势那里。

裸机：有一道是见过的，忘记在哪见了~是讲一个地方为降低孩子体内的铅含量，禁止含铅的室内壁画，但20年中这个地方的孩子的lead-level并没有显著降低。问哪个可以解释原因。选项我当时看觉得木有符合的= =有一个选项是children 数量减少了；还有一个是因为禁止了含铅汽油的汽车。感觉看到的都是反面解释的- -
还有一个是海里的一种生物在hot weather的数量比cold weather数量多很多，这种creature生活在海底，但海底的温度比海面的温度要稳定（好像是这个意思），问原因。答案我比较确定是creature 的食物在海面生活受到低温影响的那个~

呃，一直以来记忆力就超烂，想起来以后慢慢补充吧~桑心呐，看到最后的成绩瞬间崩溃...祝各位CDer都能取得好成绩！

噢对了，今天那个补充的30分钟的题是把verbal和输血混排，就是给一篇超长的文章，据说是来源于某某document的。。。一般还有一两个图表，然后列出来让你做题。和现在的考法完全不一样~GMAC要是这么改革我一定会死翘翘~啊~~

另外提醒一下，休息时间很短的，基本上8分钟去下洗手间喝口水就6分钟左右了，多休息的时间要从做题的时间扣~所以要注意把握时间啊~

还有（原谅我的间歇性回忆）注意pace！我的verbal挂掉就是pace没掌握好，当然可能也有不熟悉和水平的原因吧，前面第一题就被难住，想了很久才做掉，结果前二十题做完还剩20分钟，杯具的预兆啊（举头望青天）攒信心和能力准备二战了= =

Biofuels

Unlike other renewable energy sources, biomass can be converted directly into liquid fuels, called "biofuels," to help meet transportation fuel needs. The two most common types of biofuels in use today are ethanol and biodiesel.

Ethanol is an alcohol, the same as in beer and wine (although ethanol used as a fuel is modified to make it undrinkable). It is most commonly made by fermenting any biomass high in carbohydrates through a process similar to beer brewing. Today, ethanol is made from starches and sugars, but NREL scientists are developing technology to allow it to be made from cellulose and hemicellulose, the fibrous material that makes up the bulk of most plant matter.

Ethanol can also be produced by a process called gasification. Gasification systems use high temperatures and a low-oxygen environment to convert biomass into synthesis gas, a mixture of hydrogen and carbon monoxide. The synthesis gas, or "syngas," can then be chemically converted into ethanol and other fuels.

Ethanol is mostly used as blending agent with gasoline to increase octane and cut down carbon monoxide and other smog-causing emissions. Some vehicles, called Flexible Fuel Vehicles, are designed to run on E85, an alternative fuel with much higher ethanol content than regular gasoline.

Biodiesel is made by combining alcohol (usually methanol) with vegetable oil, animal fat, or recycled cooking grease. It can be used as an additive (typically 20%) to reduce vehicle emissions or in its pure form as a renewable alternative fuel for diesel engines.

Research into the production of liquid transportation fuels from microscopic algae, or microalgae, is reemerging at NREL. These microorganisms use the sun's energy to combine carbon dioxide with water to create biomass more efficiently and rapidly than terrestrial plants. Oil-rich microalgae strains are capable of producing the feedstock for a number of transportation fuels—biodiesel, "green" diesel and gasoline, and jet fuel—while mitigating the effects of carbon dioxide released from sources such as power plants.

You can learn more about NREL's biomass research and biodiesel research.

呵呵，终于从打击中恢复过来啦，希望各位七月战斗的CDers杀到自己满意的G!

多谢多谢，LZ再接再厉

我也是今天一战牺牲了。我觉得这次比较难，跟GWD差不多了。不过没借口，挂了就是挂了````````

LZ Verbal的情况和我一战很像。再接再厉吧！
谢谢寂静分享！
