2.13 放狗

vilanyu

虽然不知道放狗是什么意思，但是大家都在考完后分享那我也尽力回忆一下好了。在职，考得很不好，但是努力回忆一下希望对别的同学有用啦。

作文1.The director of MegaBurger restaurant wrote a letter to the owner of Cindy's which have 2 restaurant in B city，大致内容如下：加入MEGA大家庭你们可以节省运营费用、广告费用，还可以在人们都很爱逛的national cloth store开店，people都喜欢在store附近吃，而且吃store menu上有的店，你们加入我们之后，就可以吸引客户来你们店里吃高质量的食物。。

2.Nations should cooperate together issue regulations limit children's access to adult's materials on internet.

数学：
1.JJ：一列白鸟蓝鸟，先是1蓝1白，然后两蓝两白。。。可以对照机经看一摸一样
2.JJ：1hand-4inches， horse的变体，看JJ
3.the largest prime factor of 3^100+3^102+3^104, 选项：A3 Bx Cx D13
LZ这么算的是没有答案，请教大牛。 3^100（1+3^2+3^4）=91*31^100，可是没有91可以选啊。。。
4.几何题，四个同心圆，半径分别是1、2、3、4， 求最大圆减第二大圆和第三大圆比最小圆的面积的比。
5.几何题，图形是卷筒纸内核那样的圆柱体，求某条弧线。。。这题求的值是生词，和组成圆柱体的形式没看懂。
6.图标题，共有两条line，line1 line2， 分别有两个plan，planA planB，题目没看懂。

阅读：都是JJ的，女黑人化妆品、撞地球形成continent、鸟的叫声、梦~

惨痛的教训告诉我就算再忙也要认真复习，好好利用大好资源。并且，奋斗的同学保重身体，LZ周末重感冒，睡了两天，为了考试不敢吃药结果昨晚失眠到3点，考V的时候基本脑袋是懵的。工作人员连纸巾都不让我带。TAT。。。

Happy valentine‘s day

同考的一个战友说她阅读遇见了一道JJ，土星木星什么的。其他都不是，反正看个遍有不放过就好啦。我是运气好可是没有把握住机会。悔恨呐。。

Our need for sleep is somehow tied to our ability to remember. Slumber is known to improve recall in creatures from fruit flies to humans, and the reigning theory among neuroscientists has been that the waves of brain activity during deep sleep reactivate neurons that were triggered during the day, strengthening neuronal connections and cementing them into solid memories. Now Giulio Tononi, a neuroscientist at the University of Wisconsin, says sleep scientists have it all wrong: We don't sleep to remember, we sleep to forget.
About 1,000 times a night, billions of neurons undergo a synchronous one-second burst of non-REM electrical activity. The longer a person has been sleep-deprived, the bigger the initial burst. Throughout the night the bursts become progressively smaller, until they finally disappear completely just before waking. Most researchers interpret this activity as the brain slowly reinforcing synaptic connections that already exist, but Tononi noticed that after each wave, the brain goes completely silent, which never happens when we're awake.
As we sleep, says Tononi, the brain isn't building but rather downscaling, and these silences between waves play a key role. "Going up and down, up and down, basically all the neurons fire and then all are silent—it's a wonderful way for the brain to tell the synapses to get weaker," Tononi explains. He suspects the progressive weakening allows only the strong connections to survive.

The theory is unorthodox, but it does make a certain amount of sense. Without the ability to pare away unneeded information as we sleep, our brains would face a serious energy shortage as well as a space crunch: Stronger synapses are typically bigger, and real estate in the brain is precious. By proportionally weakening synapses, the brain ensures that they retain the same strength relative to each other. So when we wake up each morning, all of our synapses are weaker, and some have vanished. With them, our smallest memories from each day may be lost forever.

楼主考到的梦是这篇吗？求确认！谢谢
