解析：4.细节理解题。根据第一段第二句In1846,ThomasHenryHuxleywasappointedanassistantdoctoraboardHMSRattlesnake.可知Huxley航海是因为他在船上当医生。

5.细节理解题。根据第二段最后一句ThomasHenryHuxleyatoncerealizeditsimportanceandhowthetheoryofnaturalselectionprovidedtheworkinghypothesis(假说)wesought.可知，Huxley对自然选择理论评价很高。

6.细节理解题。根据第三段第二、三句In1863,ThomasHenryHuxleypublishedMan'sPlaceinNatureinwhichhecomparedmanandgreatapes(猿).Heclearlyshowedsimilarities.可知，ThomasHenryHuxley的书《人类在自然界的位置》为人类从类人猿进化而来提供了证据，故选D。

7.推理判断题。根据最后一段可知他一直对教育感兴趣，他是生物学教学的先锋，他选择"类群动物"的方法一直沿用至今，他生命的最后十年主要是写有关生物学的论文。由此推断出，Huxley对生物教学做出了很大贡献，故选A。C8-11.BDCA8-11.BDCA

解析：8.细节理解题。根据第三段"ResearchersattheInternationalAgencyforResearchonCancer(IARC)foundevidencethatdrinksattemperaturesabove65degreesCelsius,whenswallowed,cancausecanceroftheesophagus."可知，喝温度在65℃以上的饮料会引发食道癌，故选B项。

9.细节理解题。根据第七段中的"WHOofficialshavesincechangedtheirpositiononthatlisting.Theynowsuggestthatthetemperatureofyourhotdrinkisagreaterriskfactorthantheactualdrinkitself."可知，世界卫生组织将咖啡从“可能致癌”清单上去掉，是因为相比于饮料本身，热饮的温度对健康的影响更大。

10.推理判断题。作者是通过叙述研究结果以及研究者的观点来支撑本文的主题，即过热的饮料会引发食道癌，故选C项。

11.标题判断题。根据第一段第二句"Researcherssaylettingyourhotdrinkscooloffcouldhelpyouavoidsomekindsofcancer."和最后一段中的“itisthetemperature,ratherthanthedrinksthemselves,thatappearstoberesponsible"并结合全文内容可知，本文主要介绍了一项新的研究发现，即过热的饮料会引发食道癌，故选A项。D答案：12-15BADA解析：12.细节理解题。根据第二段中"Itdoesnotmatterasallthepandasarecutetome（这并不重要，因为所有的熊猫对我来说都很可爱）"可知，熊猫对WanYongqing来说很有吸引力。13.细节理解题。根据第四段中"Forcaptivepandas,itisimportantfortheirdailyfeedingschedules,familybackgroundanddatamanagement.（对于被圈养的熊猫来说，这对它们的日常喂养计划、家庭背景和数据管理都很重要）"可知，识别圈养大熊猫个体很重要是因为这有助于进一步的研究和数据管理。14.细节理解题。根据第六段中的"becausewildpandastendtolivealone,deepinthemountains,andtheirlivingenvironmentisvast（因为野生大熊猫往往是独居的，生活在山区，而且它们的生存环境非常广阔）"可知，野生大熊猫往往是独居的，生活在深山，因此难以追踪。15.推理判断题。根据倒数第二段"Usingthedatabank,researchershavestartedafacialrecognitionappthatcanaccuratelyrecognizecaptivepandasbyanalyzingandcomparingtheuniquefeaturesofpandafaces."可知，熊猫数据库是熊猫识别应用程序正常运行的必要条件。第二节答案：16-20BEFCA
