废话不多说，先上寂静

作文考的是寂静里的，就是把falling profits算到human resources department头上的那个，蛮好写的

IR巨难啊！！这次IR没有碰到寂静里的，好几道都是multi-source。有一道multi-source是说公司里三个人决议用哪个机器什么的。有一个女的只选最便宜的，有一个男的只选最有经验的？？= =然后给了各种机器的价钱什么的。。。很凌乱，碰到要好好看。还有一道是说一个Nation X因为有retirement age的限制，所以接近退休年龄的人employment rate降低，然后给了两张图表让你分析。。。反正很搞就是了。还有一道是说一个公司要防止与项目有benefit关系的人参与到这个项目，所以公司提了两个建议，一个是让有benefit关系的人报告给自己的direct manager，另一个是把有benefit的人给换了，问你两个做法有什么flaw?我选的是1)第一个做法中的employee可能没有direct manager,这样他就不能报告了 2)第二个做法中可能有benefit关系的人在会使这个项目更好。。。。其他的po主忘记了T_T  IR做的我以为都换库了

今天数学也有点难？虽然还是51,和上次一样，但感觉搞脑子的题比较多= =碰到了一道寂静里的 ，分子是13的阶乘，分母是(2^10)*(5^2)*(3^5)*7，答案是11*13，这个可以秒选。有一道DS，说A有a的possibility做一件事C（暂时把这件事记为C好啦），B有b的possibility做C，a和b给的好像其中一个给的是数字？A做C和B做C是独立事件，问可否得知A和B同时做C的概率？条件一忘了，但可以用条件一算出P(A)*P(B)，条件二是已知A不做C或B不做C的概率= =感觉回忆有问题，我选的是A ，大家到时候看看吧= =然后有一道图表题，是10个学生，然后一个柱状图告诉你有多少人分别读了多少书，问你读的书的中位数是什么？数字很简单，答案是2，可秒选。
有一道PS很简单的，问你1meter=30,那么1 cubic meter=?就是三次方嘛。。。答案是27000   另外有一道是寂静里的变体，说A,B,C分别要用3,5,9小时完成一个项目，那么三个人在一起做，用0.5h可以做完多少fraction的项目= =计算满烦得，大家当心。。

语法来了。。。。坑死我了。。。一道SC有好几个选项里都有on par with,好的吧我不认识= =回家有好基友告诉我是平分秋色的意思= =。。。。跪了真是。。还有一道语法是考along在句首的倒装，选项由两个是is,三个是are，应该选are吧，因为along这句话的主语是A and B...更奇葩的是一道题是考this能否指代句子？好像是不行的吧。。。但据说OG16的SC里面出现了可以用this/that指代句子= =而且确实选项里要是没有this指代句子就感觉读着很别扭= =大家斟酌一下吧0.0

逻辑里有一道超搞笑，说一个作家一直被人感觉很严肃，所以大家看待他的作品的方式也是很serious的呀，但是类，这个作家的朋友们却laugh out loud at the 作品，所以我们这么严肃看待他的作品和实际上的情况是个myth，问如何解释？选项有1）有时候laugh不一定是觉得interesting的表现 2）他的朋友们批评还是不喜欢他的作品。。。还有几个我忘了。。。。
还有一道是说多读books的人也会多去concert什么的类似的recreational activity，而少读books的人就不会多去这种activity,所以可以推出读books可以增加这种有益的acitivity的兴趣，问这个arugument有什么flaw= =选项有些迷惑，看着都感觉挺对的咋办= =

阅读碰到了redisual stress,确认以下是原文The average person is likely to feelmildly alarmed on being told that dental fillings contain locked-in stresses.We all have a somewhat hazy不清楚的 understanding that stress leads tofracture and can vaguely recall dramatic instances of stress-related failures.Thus we are likely to feel that all material stresses are without redeeming挽回的 value and should, if possible, be eliminated.

A truer picture of the behavior ofmaterials is both more complicated and more interesting. It turns out that itis difficult to work a rigid material without introducing permanent internalstresses. Most common manufacturing operations, such as turning, grinding, and peening,can set up internal stresses, and many familiar objects are subject to them,including dental fillings, computer chips, and pipelines. Butthese residual stresses can be beneficial as well as harmful. Indeed,manufacturers sometimes go to great lengths to introduce them. Manystress-related effects and recipes for obtaining them have long been known toartisans. What is new is the ability tomeasure the stress fields directly rather than inferring their nature fromwarpage and breakage. Several trends in engineering design make this analyticalcompetence important.

One of the trends is the proliferationof nontraditional materials. The best way to work a sword or to coil绕成圈 a spring弹簧 may be known, but no comparable body oflore知识 exists for ceramic transducers陶瓷转换器 or semiconductor wafers半导体晶片 or compositeairfoils复合材料机翼. Asecond trend is the trimming of safety margins修正安全边际. Bridges andother load-bearing structures have traditionally been built with large safetyfactors, but the lavish过分给予的,大量生产的 use ofmaterials required by this practice is increasingly uneconomic（原文在这里有改动，给了一些比较具体的数字）; in the case of objects that must belofted高高地升到空中 into space, a large safety factor istotally impractical. A third trend is the reduction in scale of many engineeredsystems. Residual stresses play a much more important role in the microscopicmetal微观金属 interconnects on the surface of a chip缺口 than they do in a thick electrical cable电缆.

题目

1, What does the “analytical competence”refer to?

1.   A) The ability to measure the stress field.

2.   B) The ability to infer from warpage and breakage.

2, Which of the follow is a benefit ofthe improved measurement?

1.   A) Allow structures to be built more economically.

2.   B) 忘了

3, Which of the following about residualstress is supported by the argument?

1.   A) Dental filling is beneficial

2.   B) 忘了

生词：

residual stress：残余应力

dental filling：牙齿填充物，填充蛀牙的材料

peening：锤打（金属表面）

artisan：工匠

lore: 学问、知识、传说

warpage是warp的名词：翘曲、扭曲

breakage是break的名词：断裂

proliferation：普遍出现、扩散

还碰到了一篇carbon market的，也确认是原文Cap and carbon markets are used in somecountries as mechanisms to control carbon emission. For the mechanisms to work,governments sell a certain amount of carbon emission permits to the public, andallow corporations to freely trade the permits through carbon markets. Thisway, the heavily polluting corporates, those who would incur more cost toreduce the emission than to pay for the permit for equal amount of emission,can buy the permits from the ones who can easily reduce carbon at a lower cost.Therefore carbon markets are considered effective in that it encourages thecorporates collectively to reduce carbon at the lowest cost.

It happens that due to corporates’lobbying, sometimes governments give unknown amounts of free permits to themarket. This behavior can cause confusion in the market as corporates no longerknow what the total amount of permits available in the market is. As a result,corporates cannot accurately predict the cost of getting permits and thuscannot accurately decide which the most cost-efficient way to pay for carbonemission is.

Carbon tax is a more effective way tosolve this problem. (注意有题：为什么tax比carbon market好？) Governments can utilize tax collected to takemeasurements, such as developing new technologies blah blah blah.…

另外有一片species diversity寂静里差不多，但题目出得好难= =我也是醉了。。。。还有一篇甲壳虫化石的，也和寂静差不多，认真看看没什么问题的啦。。。。

最后附上一篇蜂蜜颜色的考古原文蜂蜜颜色的确定方法原文

OPENERS: THE GOODS; The Color Of Honey: No More Bickering

THE honey sold inthose squeezable, bear-shaped bottles is always the same golden-brown color.But the raw honey gathered by beekeepers can be as white as snow or as dark asa Budweiser bottle, and it must be blended in order to produce the consistentversions familiar to shoppers. Bees, it seems, don't concern themselves toomuch with the aesthetic preferences of human consumers.

But forbeekeepers, honey hues are a primary concern. Paler honeys can be sold toproducers at a premium, on the theory that their flavors are subtler and theirtints more appealing to gourmet shoppers -- that is, those who buy their honeyin glass jars rather than plastic, ursine bottles.

A classic industrytiff, then, has found the beekeeper who contends that his honey is virtuallywhite arguing with the middleman who sniffs that it's merely a light amber.

Hanna Instrumentsinvented the C 221 Honey Color Analyzer to end such quarrels. This laptop-sizedgadget automatically grades a honey sample's color and settles once and for allwhether a beekeeper's haul merits an extra few cents a pound.

Honey colorassessment has typically been done with the help of a tool called a Pfundgrader, a black box with a thin, see-through opening and a color chart thatruns from white to brown. The sample is placed in front of the opening, and anobserver matches the honey's color to a spot on the chart. The Pfund grade isdetermined by how many millimeters that spot deviates from the far left of thechart: zero to eight millimeters is known as ''water white,'' 8 to 17millimeters is ''extra white,'' and so on. The darkest, at more than 114millimeters to the right, is dark amber.

Any system thatrelies on eyeball judgments, of course, is doomed to create bickering.

''What I see andwhat you see might be two different things,'' said Michael Bogolawski, anapplications engineer for Hanna, based in Woonsocket, R.I. ''I might say it'sthis grade, and you might say, 'No, it's closer to this grade.' With this meter,we've eliminated the subjectivity.''

The Hanna analyzeris similar to several of the company's other testing devices, which are usedwidely in the wine industry to measure pH levels and in the water industry tocheck for chlorine.

The honey gradingmachine is basically a photometer, which measures the amount of light absorbedby a substance. A tungsten lamp floods the sample with light, and a sensormeasures precisely how much is reflected. The darker the honey, the fewer therebounding photons.

The analyzer'ssoftware correlates the amount of returned light with the Pfund scale and givesa readout on a digital screen. Hanna says the analyzer's Pfund grades areaccurate within two millimeters.

Though there areabout 2.5 million commercial bee colonies in the nation, according to theAgriculture Department, Hanna understands that the market for its Honey ColorAnalyzer is somewhat narrow. Since the device made its debut in January 2004,the company's sales team has focused on attending trade shows, like theAmerican Beekeeping Federation's annual convention, and traveling ruralhighways in search of professional beekeepers. Lou Niewiecki, a Hanna salesman,estimated that the company has sold ''a few hundred'' of the analyzers, at $500apiece.

The Hanna machine,unfortunately, can't solve a more pressing problem in the industry: theinvasion of the Varroa mite, a parasitic Asian insect that feasts on beelarvae. According to the National Honey Board, this ravenous mite has alreadydestroyed up to 50 percent of the hives in California, the nation's largesthoney producer.

If the situationpersists, beekeepers may soon feel nostalgic for the days when their biggestheadache was arguing over Pfund grades.
