考研數(shù)學(xué)考前復(fù)習(xí)策略，有人說學(xué)習(xí)數(shù)學(xué)需要天賦，這是毋庸置疑的，但是客觀的說學(xué)習(xí)數(shù)學(xué)和復(fù)習(xí)考研數(shù)學(xué)是兩回事，可以說考研數(shù)學(xué)復(fù)習(xí)中天賦和智力所起的作用沒有那么大，如果你的天賦不夠，對數(shù)學(xué)概念公式定理的表達(dá)很難理解，只有一個(gè)辦法，反復(fù)閱讀，所謂書讀百遍其義自見正是這個(gè)道理，有不少天賦不夠甚至說覺得不適合學(xué)習(xí)數(shù)學(xué)的同學(xué)最后取得了好成績，并非只靠努力，其不斷的閱讀，從基本定義開始最后真的培養(yǎng)出了嚴(yán)謹(jǐn)?shù)倪壿嬎季S。

　　引言考研英語做為一門考研公共課，盡管大家都學(xué)了英文十幾，卻仍常常有總成績壓線掛在英語上的狀況，因此英語備考不僅僅是英語單詞、刷題。閱讀文章做為考研英語的高比例，只是做考研真題也許無法滿足你的閱讀量，因而以后會(huì)不定時(shí)執(zhí)行發(fā)布一篇英文美文，這種文章內(nèi)容都和考研英語閱讀文章同宗，多讀必有益處。 　　?Baby giraffes inherit aspects of their mothers’ patterning—which could give them a survival advantage if good camouflage runs in the family. 　　小長頸鹿能夠基因遺傳媽媽長頸鹿的身上的花紋遍布，假如這類花紋是長頸鹿家極致的的掩藏專用工具，那麼小長頸鹿便獲得了不可或缺的寶物。 　　Just like humans have virtually unique sets of fingerprints， every giraffe has a unique set of spots. 　　如同大家人們擁有 獨(dú)一無二指紋識(shí)別，每只長頸鹿也是有其獨(dú)一無二的花紋。 　　Not that those spot patterns really help wildlife biologists identify their study subjects in real time. 　　但在現(xiàn)實(shí)生活中，長頸鹿分別特有的花紋遍布卻給科學(xué)家鑒別其研究對象產(chǎn)生了艱難。 　　"We have more than individuals. … I have a hard time keeping track of that many humans so I have that problem with giraffes as well." Derek Lee is a wildlife biologist and population ecologist at Penn State， and with the Wild Nature Institute， a research consultancy group. 　　“大家有著多的不一樣長頸鹿人，叫我追蹤科學(xué)研究多本人我還感覺十分困難，更不要說那么雙頭長頸鹿了。”德里克.李是賓夕法尼亞州的人口數(shù)量生物學(xué)家和天然的生物學(xué)家，另外他也在天然的與當(dāng)然研究室工作中，該所是一所科學(xué)研究咨詢顧問型組織。 　　He and his collaborators have been tracking giraffes for seven years， throughout square miles in Tanzania. 　　德里克和他的朋友早已追蹤科學(xué)研究長頸鹿有七多的時(shí)間，蹤跡遍及坦桑尼亞萬平方英里的農(nóng)田。 　　And they’ve amassed a library of ， giraffe photos along the way. Photographing the animals isn’t that hard， he says. "The hard part is the tsetse flies constantly biting us on our face and hands while we’re trying to take pictures." 　　在研究過程中，她們也總計(jì)拍攝儲(chǔ)存了萬多相片的影象庫。“為長頸鹿拍攝相片并不會(huì)太難， 最痛楚的是，在我們拍攝時(shí)，蚊子一直搔擾大家，咬后大家的手和臉”他說道到。 　　Now， they’ve used image analysis software to study the spots of mothers and their calves. 　　現(xiàn)如今，德里克和他的朋友早已用圖型分析系統(tǒng)對長頸鹿媽媽和小長頸鹿的的身上花紋進(jìn)行科學(xué)研究。 　　And they found that baby giraffes inherit at least some particular elements of their patterning from their mothers. 　　她們發(fā)覺小長頸鹿會(huì)從她們媽媽的身上多多少少基因遺傳一些特殊花紋紋理。 　　Like how circular the spots are， and how jagged the edges are. 　　比如花紋的彎折水平，或是紋理邊沿的鋸齒形水平。 　　They also found that calves with larger spots were more likely to survive their first months on the savannah， perhaps because the spots better mimic the dappled sunlight in the bushes where calves like to hide from hungry lions and hyenas. 　　她們另外也發(fā)覺，的身上花紋很大的幼鹿在其剛生沒多久時(shí)更非常容易在草原地區(qū)生存，這也許是由于這種大花紋與太陽光灑進(jìn)灌叢落下來的朦朧身影類似，而幼鹿則喜愛躲藏在其中以避開饑火燒腸的獅子座和流浪狗。 　　The results—and a lot of giraffe patterns—are in the journal PeerJ. 　　此項(xiàng)發(fā)覺和很多長頸鹿照片在同刊雜志期刊中皆可查看。 　　It’s perhaps not surprising that a physical characteristic that protects an individual from being eaten passes the test of Darwinian natural selection—and get passed along to offspring. 　　維護(hù)人存活的生理學(xué)特點(diǎn)被愛因斯坦適者生存規(guī)律選定并代代相傳這或許并不使大家覺得詫異。 　　"The fact these things are heritable and they did affect juvenile survival makes us feel like evolution is acting on these spot traits." So if mom’s camouflage is good， her babies， too， might have the spots that make them harder to spot. 　　“這一客觀事實(shí)——即長頸鹿的花紋能夠基因遺傳并且事關(guān)幼鹿的生死攸關(guān)——我們一起意識(shí)到進(jìn)化論已經(jīng)這種花紋紋理上開演。”因此假如媽媽的花紋掩藏是切實(shí)可行的，她的幼鹿便會(huì)基因遺傳這種紋理讓自身無法被捕食者發(fā)覺。 　　 　　 ?
