[标题判断题。通读文章可知，在星期二墨西哥发生强烈地震后，并不是只有救援人员和成千上万的志愿者参与了救援行动，来自海军犬队的十五条狗也参与了救援工作。故选D项。]5．WhatmakesFridaasocialmediastar?A．Herrescuerecordsandtirelesswork.B．Hercooperationwiththerescueteam.C．Hercoolappearancewithsomespecialdevices.\nD．Herabilitytosearchspacesbeyondhumans'reach.A

[词义猜测题。根据“thepresenceofasurvivor”和转折连词“but”可推断画线单词corpse与survivor意义相反，其意思为“尸体”，故选C项。]7．Itcanbeinferredfromthelastparagraphthat________.A．FridawillachievenothingB．FridawillprobablyworkmiraclesC．moredogswillbesenttotheareaD．therestoftherescuewillbedonebydogsB

[推理判断题。根据第一段的“thevaccine(疫苗)—withitsexcellent36percenteffectiveness—wouldnotpreventeveryonefromgettinginfectedwiththeannoyingvirus”可知，疫苗的有效率为36%，所以并非所有的疫苗都有效，故A项正确。]9．Whydomanypartsofyourbodysufferwhileyou'rerecoveringfromtheflu?A．Becauserecoveryfromillnessispainful.B．Becauseyourimmunesystemisworkingagainstyourdefensesystem.C．Becauseyourbodyisfightinghardagainsttheflu.D．Becausetheinfluenzavirusattacksyournose,throatandotherparts.C [细节理解题。根据第二段最后两句可知，几乎所有的流感症状与病毒本身关系不大，它们主要是免疫系统对病毒的反应造成的，对病毒的清除是你感觉疼痛的原因，因此身体不舒服是因为身体在清除病毒，故C项正确。]\n10．Theunderlinedword“fun”inParagraph4canbereplacedby________.A．joy B．battle C．action D．programB [词义猜测题。根据fight可判断battle符合要求。免疫系统开始工作意味着真正的战斗的开始。]11．What'sthemainideaofParagraph4?A．Thefightbetweentheinnateimmunesystemandtheadaptive.B．Thecategoriesoftheimmunesystem.C．Thewaytheimmunesystemworks.D．Theprocessofthedevelopmentoftheimmunesystem.C

[根据空前“Iwaswokenbythealarmclockat6a．m.(早上6点钟我被闹钟叫醒了)”和空后“ThenIcheckedmyphoneformessages，turnedontheTVformymorningnews，startedmakingmycoffeeandfinallyhittheshower.(然后我查看了手机中的消息，打开电视听早间新闻，开始煮咖啡，最后洗了澡)”可知，B项Severalminuteslater，Iturnedoffthealarmclock.(几分钟后，我关闭了闹钟)能够承接上文并且与下文连接通顺。该选项中的thealarmclock为原词复现。故选B项。]\n4．A [根据空前“Luckily，thehumanbodyhasamazingdefenseagainstharmfulgerms.(幸运的是，人体对有害细菌具有惊人的防御能力)”和空后“Ourwhitebloodcellsarelikesoldierscomingtotherescue.(我们的白细胞就像士兵一样来营救我们)”可知，A项Ourskinisthefirstlineofdefense.(我们的皮肤是第一道防线)能够承接上文并且与下文连接通顺。故选A项。]5．E [根据空后“Ifyouhavechildren，itisevenmoreimportanttosettheexamplebecausechildrenareknowntolearnfromadults.(如果你有孩子，树立榜样就更重要了，因为众所周知，孩子向成年人学习)”可知，E项Mostimportantly，itisourdutytosettherightexampleforfriendsandfamily.(最重要的是，为朋友和家人树立正确的榜样是我们的责任)是本段的主题句。该选项中的settheexample在下一句中出现了。故选E项。]
