Unit5单元拔尖检测第一部分第一节A【主旨大意】本文主要介绍了长江江豚的相关内容。1.C细节理解题。根据“Scientistssaythatthefinlessfreshwater...forover20millionyears”可知，长江江豚已经在长江中生存了两千多万年。故选C。2.C细节理解题。根据“Dangers:Dredging(挖掘)oftheirhabitat.HeavyboattrafficintheYangtzeRiver.Insecticide(杀虫剂)andmercury(汞).”可知，危险不包含游泳者。故选C。3.A细节理解题。根据“Maindiet”中的“Fish”以及“Shrimp”可知，它主要吃鱼和虾。故选A。B【主旨大意】本文主要介绍了与中国相关的一些地理知识。4.C细节理解题。第一段提到中国的人口数量、面积大小以及地理位置，并未提及世界上最大的国家。故选C。5.B段落大意题。第三段主要介绍了中国最重要的两条河流——黄河和长江的相关内容。故选B。6.C词义猜测题。根据最后一段内容可知，中国有河流、沙漠和雨林，画线单词应表示“多样的”。故选C。7.D细节理解题。根据第三段最后两句可知，黄河对于中国人来说非常特别，因为它是中华文明的发源地。故选D。C【主旨大意】本文主要讲述了JohnMuir对自然的热爱和保护自然环境的行动。8.A推理判断题。根据第二段的“Thehardworklikeplowing(耕)fieldsanddiggingawellmadehimstronginboththemindandthebody.”可知，此处提及辛苦劳作，因此这句话应放在①处，故选A。9.C细节理解题。根据“In1849,whenJohn...UnitedStates.”“Helovedlearning,too,andatnighthestudiedmanysubjects.”“Butatage29,hehad...losthisvision(视力).”“Ayearlater,whenJohn...hefoundhiscallinginlife.”和“In1892,JohnMuirstarted...protecttheenvironment.”可知，正确的顺序是a-b-d-e-c，故选C。10.B细节理解题。根据“Hebuiltclocksanddesignedmachinesthatmadefarmingeasier.”可知，John自己设计机器，而不是购买机器，故选B。11.D词义猜测题。根据“Ayearlater,whenJohnsaw...foundhiscallinginlife.”可知，一年以后，他开始明白自己找到了人生的使命。因此“calling”意为“使命”，选项A、B均是“叫喊”，C项应为“打电话”，故选D。D【主旨大意】本文主要介绍了世界上最大的海啸。12.B推理判断题。根据“The8.3earthquakeshook40millioncubicyards(立方码)...”可知作者列举这些数字说明了海啸造成的危害，表明了海啸的强大威力。故选B。13.B推理判断题。根据“Thesetwounluckypeoplewereonafishingboatinthebaywhenthewavearrived.”可知有两个不幸的人在海啸中去世了，选项B“然而，1958年的海啸造成两人死亡。”符合语境。故选B。14.C细节理解题。根据“mostscientistsnowregardthelandslideasthetruereasonforthewave”可知大多数科学家现在认为滑坡是造成海啸的真正原因。故选C。15.D最佳标题题。本文主要介绍了世界上最大的海啸的相关信息，“世界上最大的浪”作为标题最合适。故选D。第二节【主旨大意】本文主要谈论了保护动物的一些建议。16-20EFADC第二部分第一节【主旨大意】本文主要介绍了森林逐渐减少以至于有一天会消失的问题，告诫人们要保护环境，保护森林。21.A根据“tobuildhouses”可知是需要更多的木材来建造房屋，故选A。22.C根据“manypeoplearecuttingdownthetreesintheforests”以及“Theareasofforestsaregetting...”可知人们在砍树，所以森林的面积越来越小。故选C。23.D【点拨】根据“20or30years”可知是20年或30年后，此处用“in
