2、家，同時他也是一名偉大的建筑師。Part of what made Bucky so special was his concernfor the pla and humanity.他如此特別的部分原因是他很關(guān)心地球和人類。When you have a shortage of resources, he said, you get war.他說當(dāng)缺乏資時，就會發(fā)生戰(zhàn)爭。Thus, he developed an idea called prehensiveAnticipatory Design Science.所以，他創(chuàng)始了一種觀念，叫作“全面預(yù)期設(shè)計科學(xué)”。Its a mouthful,

3、but what it entails is his belief that to solve humanitysmajor problems.這個名字有點(diǎn)拗口，但它需要巴基的信念來解決人類主要問題。We have to look forward to the future; we have to anticipate what will beeproblems asresources diminish, etc.我們必須展望將來;我們必須預(yù)期會出現(xiàn)的問題，比方資減少等等。His goal?

5、rms of onions-cooked, raw, dehydrated-containsulfurpounds.要知道，新穎的、脫水的、烹飪的洋蔥，無一例外含有硫化物。When your pet ingests onions, thesepounds are broken down into what are known asdisulphidepounds;寵物攝食洋蔥，化合物就分解成二硫化物，紅細(xì)胞膜“中毒”，形成海恩茨氏小體的突起小泡。These bubbles make the red blood cell more rigid, and weaken its outermembr

6、ane, whichmeans not only that the cell cant flex and twist as it circulates in the body,but that it is morelikely to rupture.海恩茨氏小體使紅細(xì)胞僵硬，外膜受損。紅細(xì)胞在體內(nèi)循環(huán)，無法彎曲和改變，更易破裂。Now, the main function of red blood cells is to circulate oxygen throughout the body.紅細(xì)胞的主要功能是循環(huán)體內(nèi)的氧氣。Withoutenough of these, the anima

7、l bees anemic, andif the bone marrow isnt givenenough timeto regenerate new red blood cells-it may even die.紅細(xì)胞的缺失誘發(fā)動物貧血;假設(shè)骨髓沒有及時更新紅細(xì)胞，動物就會喪命。This also explains why the effects of oniontoxicity can take a few days to show up, and why evenvery small amounts of onions can stillhave a cumulative damagi

9、ponsible for flexiblelearning andreasoning.人類和其他哺乳動物的前腦頂層已經(jīng)進(jìn)化為大腦皮層，這一構(gòu)造主管彈性學(xué)習(xí)和推理才能。Early neuroanatomists thought that the forebrainroof was small and simple in birds, with itsforebraininstead being dominated by structures in its base, called the basal ganglia.早期的神經(jīng)系統(tǒng)科學(xué)家認(rèn)為鳥類的前腦頂層在大腦中面積小，構(gòu)造簡單，且并非由大腦基底

10、部名為基底神經(jīng)節(jié)的構(gòu)造組成。Without anelaborate forebrain roof, it seemed that birds couldnt be very smart.因此，鳥類并不擁有復(fù)雜精妙的前腦頂層，這似乎決定了鳥類智商有限。Recent research shows that birds are a lot smarter than scientists once thought.最近的研究說明鳥類要比科學(xué)家想象的聰明得多。To give just afew exles, the New Caledonian crow can manufacture and use

11、tools.例如，新喀里多尼亞烏鴉會制作和使用工具。The African grey parrotcan learn to classify objects into categories, and the Florida scrub jaystores food in dozens ofcaches and can remember their locations for future use.非洲灰鸚鵡能學(xué)會對東西進(jìn)展分類，佛羅里達(dá)灌叢鴉會將食物存儲在不同的地方，并且能記住位置，以備將來之需。It turns out that neuroanatomists had it all wrong about bird forebrains.結(jié)果是神經(jīng)解剖
