批注[微软用户1]:正确答案：C。原文这部分介绍了各种不同的edgesillustratethattheboundariesoftectonictesareneat,thinlines

从两处可以看出应该是要体现其复杂性。A与原文 ，原文并没有对B做出解释，D原文给出的是googaction常发的地方，而不是little~ provideexamplesofareasoftectonicteswherelittlegeologicactionoccursQ2Theword“converge”inthepassage

[微软用户2正确答案：D。这movecloser，一种moveapart。对第三种的描写是neither…nor…既move

theboundaries testhatmost也不，因此应该是与前两种都不Q3Whichofthesentencesbelowbestexpressestheessentialinformationinthehighlightedsentenceinthepassage?IncorrectchoiceschangethemeaninginimportantwaysorleaveoutessentialinformationVolcanicactivityisresponsiblefortheformationofthePacificseafloorintheinteriorofthePacificte.ManyvolcanoesinthePacificOceanarenolongeractiveandhave eislandsthatsupportcoral.TherearemanyislandsinthePacific

断divege是分开，converge是聚合。所以答案为D。批注[微软用户3]:正确答案C．根据这一段的第一句可以看出后面是在举例说内陆平静的excton。，B，D选项都是句子的细节部分，不能表达出其目的。所以不选。becausemanyarenolongeractiveandsomearecompleyovergrownwithclosetclosetinmeaningQ4Theword“instructive”inthepassageQ5Q5Theword“eroded”inthepassageclosestclosestinmeaningwornQ6Inparagraph3,whatisthe

批注[微软用户4]:正确答案：C。instructive是有意义的，教育性的。A只有C是有益的，教育性的，意思吻批注微软用户5正确答案A。这句话说不同的岛屿看起来经历了相似如果经历的时间更长应该会被海水daysofthedevelopmentofthetheoryof“侵蚀”的更厉害。所以答案选betweenthescientificcontributionofJames tetectonics,CanadianDalyandTuzo TuzoWilsonrealizedthatthis

[l6正确答案A。根据两个科Wilson发现……那么肯定是使板块ofislandchainsthat expressionofalong-livedvolcanicsource理论进一步发展了。所以B不对。Daly’s exnationofvolcanicislandformationformulatedbyDalyParagraph3ismarkedwithanQ7Whydoestheauthorprovidetheinformationthat“thedatingoflavasintheHawaii(andother)chainsshowedthattheiragesincreaseawayfromthepresentlyactive

C虽然逻辑关系对，但文中只给了夏威夷岛一个例子。所以C不选。D说使解释流行，之前daly只是给了理确的。选A[l7正确答案：D。这个题很简[l7正确答案：D。这个题很简案啦。JustasDalyhadsuggested。 betweentheHawaiiIsland

[l8]:正确答案：Bmantle首先是于很深的地方，其次活动时间很长。因此A，C，D都不对。所以正确答案为B。[l9正确答案：A。定位到这一段的第二句。D选项虽然也detectchangesinmantlemeasuretherigidityof inwhytheseafloorParagraph5ismarkedwithanQ10Whatcanbeinferredaboutthe
