阅读~我遇到那个JJ里面说到的耐用品购买的时候消费者不比较PRICE的那一篇~ 有一个说最新的关于海豹的研究~说两种不同种类的海豹生宝宝的时候采取什么不同的脂肪存储机制balabala~感谢我亲爱的同学大吉！她考古到啦~GWD的~原文如下 Until recently, zoologists believed that all species of phocids (true seals), a pinniped family, use a different maternalstrategy than do otariids (fur seals and sea lions), another pinniped family. Mother otariids use a foraging strategy. They acquire moderate energy stores in the form of blubber before arriving at breeding sites and then fast for 5 to 11 days after birth. Throughout the rest of the lactation (milk production) period, which lasts from 4 months to 3 years depending on the species, mother otariids alternately forage at sea, where they replenish their fat stores, and nurse their young at breeding sites. Zoologists had assumed that females of all phocid species, by contrast, use a fasting strategy in which mother phocids, having accumulated large energy stores before they arrive at breeding sites, fast throughout the entire lactation period, which lasts from 4 to 50 days depending on the species. However, recent studies on harbor seals, a phocid species, found that lactating females commenced foraging approximately 6 days after giving birth and on average made 7 foraging trips during the remainder of their 24-day lactation period. The maternal strategy evolved by harbor seals may have to do with their small size and the large proportion of their fat stores depleted in lactation. Harbor seals are small compared with other phocid species such as grey seals, northern elephant seals, and hooded seals, all of which are known to fast for the entire lactation period. Studies show that mother seals of these species use respectively 84 percent, 58 percent, and 33 percent of their fat stores during lactation. By comparison, harbor seals use 80 percent of their fat stores in just the first 19 days of lactation, even though they occasionally feed during this period. Since such a large proportion of their fat stores is exhausted despite feeding, mother harbor seals clearly cannot support all of lactation using only energy stored before giving birth. Though smaller than many other phocids, harbor seals are similar in size to most otariids. In addition, there is already some evidence suggesting that the ringed seal, a phocid species that is similar in size to the harbor seal, may also use a maternal foraging strategy. 还有一篇阅读说欧洲队美国印第安人的好像是自主权?还是独立权？反正是SOV什么什么的单词....说欧洲人对美国印第安人的这个SOV....又开始是承认的~后来由于欧洲由英国占多数话语权~英国好像对这个SOV....不是很认可....后来由于美国的什么运动又让这个sov....被认可...
数学有那个什么1除以（1-根号二分之一）~ 还有一张长方形的纸上剪掉最大的一个半圆~求长方形的宽还是求什么玩意~条件（1）半圆的半径（2）半圆的弧长 还有~数轴上的三个数~R方小于4小于U方小于v方，问R是不是在UV之间。条件（1）......忘记了....（2）U小于0小于V 还有一个人买东西B,C D B的价格是C的2倍还多三，D的价格比C多2.求D的价格。条件（1）三样花了多少多少钱（2）B比D多花了多少多少钱
CR有一道是说有一种欧洲的什么什么糖浆是添加到葡萄酒里面的~为了让酒甜一点~然后这种糖浆会导致一种C的病~这种糖浆一般是在葡萄种植条件不好导致酒酸的时候调味~还有就是就酒经过长途运输之后改变味道的~问下列哪个选项最没有被文章支持... 还有一道是GWD的原题~说一种皮肤病不能通过肉眼判断~然后原来有一种TEST的方法~现在发明一个仪器~然后问知道下列哪一个条件可以判断这个仪器是不是在以后会使用很多....感谢我亲爱的同学大吉！她考古到啦~原文如下 Because visual inspection cannot reliably distinguish certain skin discolorations from skin cancers, dermatologists at clinics have needed to perform tests of skin tissue taken from patients. At Westville Hospital, dermatological diagnostic costs were reduced by the purchase of a new imaging machine that diagnoses skin cancer in such cases as reliably as the tissue tests do. Consequently, even though the machine is expensive, a dermatological clinic in Westville is considering buying one to reduce diagnostic costs. Which of the following would it be most useful for the clinic to establish in order to make its decision? A. Whether the visits of patients who require diagnosis of skin discolorations tend to be shorter in duration at the clinic than at the hospital B. Whether the principles on which the machine operates have been known to science for a long time C. Whether the machine at the clinic would get significantly less heavy use than the machine at the hospital does D. Whether in certain cases of skin discoloration, visual inspection is sufficient to make a diagnosis of skin cancer E. Whether hospitals in other parts of the country have purchased such imaging machines作者: 救救痘包 时间: 2012-7-13 23:01
还有一个数学题~有图~不会贴~试试附件可以不可以....图就是那么个图~D是15度~求角A和角EFA的和~条件（1）好像是角DGE的度数~反正根据（1）能求出来角DEG~(2)角B是15度~~大概意思哈字母不准~作者: 救救痘包 时间: 2012-7-13 23:02
