4、商路上；Teotihuacn谷本身的黑曜石資源；山谷的大量灌溉的潛力。要想說清楚其他因素所扮演的角色就難的多了——比如，Teotihuacn作為圣地的宗教意義；墨西哥谷及周邊直到公元前第一個(gè)千年的歷史情況；Teotihuacn精英階層的3遠(yuǎn)見；最后還有自然災(zāi)害的影響，諸如公元前一千年的火山噴發(fā)。Whichofthefollowingcanbeinferredfromparagraphs23abouttheVolcaniceruption

9、anwasthecenterthatdidariseasthepredominantfceintheareabythefirstcenturyA.D.最后一個(gè)因素至少從環(huán)境上與Teotihuacn古城的崛起有牽連。在公元前200年之前，有很多相對的小的中心共存于墨西哥谷及附近。大約在此時(shí)，這些中心中的最大者，Cuicuilco，受到了一次火山噴發(fā)的嚴(yán)重影響，它的大部分耕地被火山熔巖所覆蓋。伴隨著Cuicuilco作為一個(gè)潛在對手的消失，

10、任何一個(gè)相對較小的城鎮(zhèn)都有可能在中央墨西哥形成領(lǐng)導(dǎo)性的經(jīng)濟(jì)政治力量。盡管考古學(xué)證據(jù)清晰地表明Teotiluacan確實(shí)在公元1世紀(jì)成長為這一地區(qū)的主要力量。【TPO8(1)6#7#】Whatcanbeinferredfromparagraph3aboutCuicuilcoprito200B.C.○Itwasafairlysmallcityuntilthatdate.○ItwaslocatedoutsidetheValleyofMexic

15、與其說問題是它們?yōu)槭裁磿?huì)在冬天很冷的時(shí)候離開，不如說是它們是如何找到路的。許多年來，人們一直為這個(gè)問題所困惑，直到1950年代，一個(gè)叫GustaveKramer的科學(xué)家提供了答案，在這個(gè)過程中也提出了新的問題。【TPO11(2)1#】Whichofthefollowingcanbeinferredaboutbirdmigrationfromparagraph1○B(yǎng)irdswilltakethemostdirectmigratyroute

16、totheirnewhabitat.○Thepurposeofmigrationistojoinwithlargergroupsofbirds.○B(yǎng)irdmigrationgenerallyinvolvesmovingbackfthbetweennthsouth.○Thedestinationofbirdsmigrationcanchangefromyeartoyear.這道題的關(guān)鍵詞明顯不是很好找，而且排除法的話答案又太長，所以看本段

17、的開頭，說南美的鳥春天飛去北方，而北美的鳥冬天飛去南方，所以答案是C，betweennthsouth，其他的選項(xiàng)都沒有相關(guān)信息5SoinanothersetofexperimentsKramerputidenticalfoodboxesaroundthecagewithfoodinonlyoneoftheboxes.Theboxeswerestationarytheonecontainingfoodwasalwaysatthesamep
