從兩處可以看出應(yīng)該是要體現(xiàn)其復(fù)雜性。A與原文 ，原文并沒有對B做出解釋，D原文給出的是googaction常發(fā)的地方，而不是little~ provideexamplesofareasoftectonicteswherelittlegeologicactionoccursQ2Theword“converge”inthepassage

[微軟用戶2正確答案：D。這movecloser，一種moveapart。對第三種的描寫是neither…nor…既move

斷divege是分開，converge是聚合。所以答案為D。批注[微軟用戶3]:正確答案C．根據(jù)這一段的第一句可以看出后面是在舉例說內(nèi)陸平靜的excton。，B，D選項都是句子的細(xì)節(jié)部分，不能表達(dá)出其目的。所以不選。becausemanyarenolongeractiveandsomearecompleyovergrownwithclosetclosetinmeaningQ4Theword“instructive”inthepassageQ5Q5Theword“eroded”inthepassageclosestclosestinmeaningwornQ6Inparagraph3,whatisthe

批注[微軟用戶4]:正確答案：C。instructive是有意義的，教育性的。A只有C是有益的，教育性的，意思吻批注微軟用戶5正確答案A。這句話說不同的島嶼看起來經(jīng)歷了相似如果經(jīng)歷的時間更長應(yīng)該會被海水daysofthedevelopmentofthetheoryof“侵蝕”的更厲害。所以答案選betweenthescientificcontributionofJames tetectonics,CanadianDalyandTuzo TuzoWilsonrealizedthatthis

[l6正確答案A。根據(jù)兩個科Wilson發(fā)現(xiàn)……那么肯定是使板塊ofislandchainsthat expressionofalong-livedvolcanicsource理論進一步發(fā)展了。所以B不對。Daly’s exnationofvolcanicislandformationformulatedbyDalyParagraph3ismarkedwithanQ7Whydoestheauthorprovidetheinformationthat“thedatingoflavasintheHawaii(andother)chainsshowedthattheiragesincreaseawayfromthepresentlyactive

C雖然邏輯關(guān)系對，但文中只給了夏威夷島一個例子。所以C不選。D說使解釋流行，之前daly只是給了理確的。選A[l7正確答案：D。這個題很簡[l7正確答案：D。這個題很簡案啦。JustasDalyhadsuggested。 betweentheHawaiiIsland

[l8]:正確答案：Bmantle首先是于很深的地方，其次活動時間很長。因此A，C，D都不對。所以正確答案為B。[l9正確答案：A。定位到這一段的第二句。D選項雖然也detectchangesinmantlemeasuretherigidityof inwhytheseafloorParagraph5ismarkedwithanQ10Whatcanbeinferredaboutthe
