The chemical adenosine is released by brain cells when those cells are active. Adenosine then binds to more and more sites on cells in certain areas of the brain, as the total amount released gradually increases during wakefulness. During sleep, the number of sites to which adenosine is bound decreases. Some researchers have hypothesized that it is the cumulative binding of adenosine to a large number of sites that causes the onset of sleep.

Which of the following, if true, provides the most support for the researchers' hypothesis?

正确答案: B

回馈CD啦~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
第一次考G,刚刚好700,不算太好但也不差~~~~~~~
作文考试之前真的没怎么练,考试的时候有很紧张,打字老错,感觉最后都没有写满字数。。。。汗
argument:一家叫Provincia的航空公司 今年油价上涨 导致飞机运营成本上涨
这家P公司又增加了航线 发现利润降低 而又发现同行业的公司并没有因为油价上涨而导致利润下跌
P公司认为是新增的航线才导致的利润下跌 所以要停止新航线来挽回利润损失
据说这篇作文还是很高频的
issue:
收入的分配是否应该取决于其工作对社会贡献的大小,,,,,
其实我的两篇文章都不难,但是谁让我自己不练呢。。。。。。。。。。。作文觉得准备了模板还不够,还是要练下,打字速度快也很重要喔


数学部分:感觉不难,但是还是没有拿到51.不知道问题出在哪里了。。。。。。
只能记得两题了。。坐标上的三个点(-1,6)(0,0)(2,1)分别是一个平行四边形上的四个点,请问这样的平行四边形有几个?
还有一道是:一个8000多的数字乘以4000多的数字,除以另外3个数字,答案好像是13/7.
其他题真的是记不起来的,但是都不是很难的,

语文部分:
考之前看到CD上有之前考过的同学说感觉语法跟以前做过的不太一样,这个我还真没觉得,感觉跟GWD的很像啊,而且最后一道题还是GWD里的
Charles Darwin observed, natural selection operates whenever individuals of one genetic composition are better at reproducing than that of others
A. that of others
B. the other

C. another
D. those of another
E. that of the next

这题语法题正好是最后一题,呵呵,时间来不及了就正好立马选上
考试过程中觉得最痛苦的是逻辑,,,看不懂,脑袋之间放空啊,最后第二道逻辑题优势GWD里的
The chemical adenosine is released by brain cells when those cells are active.
Adenosine then binds to more and more sites on cells in certain areas of the
brain, as the total amount released gradually increases during wakefulness.
During sleep, the number of sites to which adenosine is bound decreases. Some
researchers have hypothesized that it is the cumulative binding of adenosine to a
large number of sites that causes the onset of sleep.

Which of the following, if true, provides the most support for the researchers'
hypothesis?
答案选B

阅读部分的四篇都是寂静里的,但是问题好像都不一样,第一篇是manufacturer,retailer这篇,有一个问题有点难,是infer的题,选项有顾客以为retailer从manufacturer进货价格都固定的,,,,,汗,,,真的记不住了。第二篇是美国是债务国这篇,第一个问题是主旨大意,第二个是直接投资和portfolio的区别是什么,我选的是有没有这个公司的share之类的。。。第三篇是蟹状星云,JJ上出现过但是问题不一样,这篇很长的,我还是读了两遍。第一问是主旨大意题,我记得选的是,讲了一个最近的研究,并且解释了这个现象。。。其他题目继续记不住。。。。。第四篇是动物在冷的地方血液结成冰块这篇,举了frog的例子,,,题目不难

我能记住的就是这么多了,希望能帮到大家哈!
Even after long periods of sleep when adenosine is at its lowest concentration in the brain, the number of brain cells bound with adenosine remains very large.
Caffeine, which has the effect of making people remain wakeful, is known to interfere with the binding of adenosine to sites on brain cells.
Besides binding to sites in the brain, adenosine is known to be involved in biochemical reactions throughout the body.
Some areas of the brain that are relatively inactive nonetheless release some adenosine.
Stress resulting from a dangerous situation can preserve wakefulness even when brain levels of bound adenosine are high.
