阅读寂静

wzjfox

一战悲催了，阅读寂静中了两篇，一篇是寂静上免疫系统那篇1）免疫系统：
P1：以前认为压力大让下丘脑（河马体）释放荷尔蒙跟肾上腺素（maybe)，切掉小鼠下丘脑，压力刺激下，其他激素也产生了

P2:stress释放一种化学物质→刺激白细胞活动→白细胞产生化学物质→是白细胞到达伤口处还是化学物质到伤口处？？，增加其它免疫细胞的免疫功能，更surprisely,白细胞还可以进入大脑，神经元什么的(这里没有看懂。。。是白细胞能进入大脑还是白细胞扮演神经元的作用，神经元这后面有出题）还出了一道态度题
P3:过度压力使免疫系统过度反应变得敏感
2）高储蓄率
中了寂静版本二，文章简单，题目变态！！！版本二的第二段长段分析会出一道作者态度题，然而我5个单词就认识一个skeptical。。。记得其它选项是contentional（还是什么记不清了）还有一个是speculative，这次考试speculation出了n多次。。然而并不认识这是什么鬼
3）出了篇寂静上没看到的no-tilling（第一篇阅读。。）
P1:犁地导致(water and wind)，反正各种不好，水土流失什么的
P2:no-tilling各种好，把a（抱歉我忘记了这个长单词，第三段有提示a可以作为动物饲料）这种东西放在地里，可以防止土壤风化，增加营养
P3:为什么notilling这么好，农民不用呢？因为a可以用来做饲料呀！把a放在地里不是浪费了吗！农民缺乏知识，而且很穷买不起机器。。。
问题全都是关于no-tilling的
第四篇阅读记不住啦，逻辑中了一道寂静里蜘蛛和毒蛾子那个，一模一样的
出了很多态度题。至少2道以上。。问作者的态度 contemptuous  inquisitive  speculative  noncommittal？？？
数学DS出了两根棍立在地上求交点离地面高度那道题，PS 2*10^?能被。。一定要去看数讨君大神的解析呀~还有什么样本平均数是1400，抽到1500的标准差是1.6，问抽到1200标准差是多少？
6月再见！

是原文吗？

P1 说耕种农业（till farming)这样那样的，又烧树叶又怎么的来维持Soil的温度之类（大概就是保养土地），对Poor 国家的人来说怎么怎么的（失忆了！）
P2 介绍了un-tilling farming( or no-till farming),说这种农业各种好啊！最后一句话说比起耕种农业需要大量的人力物力，no-till farming reduce cost!( 有点记不清了）
P3 说但是在发展中国家，要人们接受非耕种农业很困难。

No-Till: How Farmers Are Saving the Soil by Parking Their Plows
The age-old practice of turning the soil before planting a new crop is a leading cause of farmland degradation. Many farmers are thus looking to make plowing a thing of the past

By David R. Huggins and John P. Reganold

John Aeschliman turns over a shovelful of topsoil on his 4,000-acre farm in the Palouse region of eastern Washington State. The black earth crumbles easily, revealing a porous structure and an abundance of organic matter that facilitate root growth. Loads of earthworms are visible, too—another healthy sign.
Thirty-four years ago only a few earthworms, if any, could be found in a spadeful of his soil. Back then, Aeschliman would plow the fields before each planting, burying the residues from the previous crop and readying the ground for the next one. The hilly Palouse region had been farmed that way for decades. But the tillage was taking a toll on the Palouse, and its famously fertile soil was eroding at an alarming rate. Convinced that there had to be a better way to work the land, Aeschliman decided to experiment in 1974 with an emerging method known as no-till farming.

Most farmers worldwide plow their land in preparation for sowing crops. The practice of turning the soil before planting buries crop residues, animal manure and troublesome weeds and also aerates and warms the soil. But clearing and disturbing the soil in this way can also leave it vulnerable to erosion by wind and water. Tillage is a root cause of agricultural land degradation—one of the most serious environmental problems worldwide—which poses a threat to food production and rural livelihoods, particularly in poor and densely populated areas of the developing world [see “Pay Dirt,” by David R. Montgomery, on page 76]. By the late 1970s in the Palouse, soil erosion had removed 100 percent of the topsoil from 10 percent of the cropland, along with another 25 to 75 percent of the topsoil from another 60 percent of that land. Furthermore, tillage can promote the run-off of sediment, fertilizers and pesticides into rivers, lakes and oceans. No-till farming, in contrast, seeks to minimize soil disruption. Practitioners leave crop residue on the fi elds after harvest, where it acts as a mulch to protect the soil from erosion and fosters soil productivity. To sow the seeds, farmers use specially designed seeders that penetrate through the residue to the undisturbed soil below, where the seeds can germinate and surface as the new crop.

回复皮卡丘：貌似是的...我是14号考的没换

回复bzy::
跟实战文章很像，尤其是特别长的那一段，重点看长的那一段

我可能把Aeschliman这个人和作物残骸弄混了。。实在是记不住了，附件文章旁边的editor总结,和考试文章框架一样～

想问下楼主中的机经在哪里看的？我没找到....谢谢！
