课时作业(十一)Ⅰ.阅读理解A【语篇解读】本文是一则旅游广告，目的是吸引更多人关注MagicalHistoryTour，让人们在GreaterPortland地区起先探究历史之旅。1．答案与解析：A推理推断题。依据本文第一句话可知，这是探究历史遗迹的旅行，而第一句话中的“GreaterPortlandthatyou'veneverseenormaybedidn'tevenknowexisted”说明这是一个鲜为人知的地方，与A项中的“exploreunfamiliarhistoricsites”吻合。2．答案与解析：B细微环节理解题。在Tickets部分提到，一般成人的票价是35美元，MHS成员的成人票价是25美元，18岁以下的青少年是5美元。题干里的“acouple(oneisMHSMember)andakid”是指一对夫妇和一个孩子，夫妇中有一个人是MHS成员，所以票价为“25＋35＋5＝65”，故选择B项。3．答案与解析：D细微环节理解题。依据Volunteering部分其次句话中的“Volunteers...aregivenafreetickettothetour”可知，志愿者可以获得一张免费旅游票，与D项表述吻合。由第一段中的“begreetedbyguidesateachlocation”可知B项错误。依据Tickets部分的“Getyourticketsonline...at489CongressStreet”可知，可以网上订票，可以打电话订票，也可以在博物馆商店购票，但是并未提及是否能通过电子邮箱订票。依据其次段中的“presentinganexcitingmixofbothnewsitesandfavoritesfromthepastfouryears”可知，并不是只有新景点可以选择，还有一些老景点以供参观。B【语篇解读】本文是一篇说明文。探讨发觉，火蚁群体的生产力高，在挖洞窟通道过程中，只有极少部分的火蚁参与完成大部分的工作，而其他火蚁不作为。这一发觉可以应用于机器人技术。4．答案与解析：D细微环节理解题。依据第一段中的“Fireantstunnelsgotdugefficientlybyonlyasmallpercentageofthegroupdoingmostofthework.Freeloaders,theyjustsitaroundwhiletheirhard­workingcolleaguesgetthingsdone”可知，火蚁的大部分挖洞窟通道工作都是由一小部分蚁群来完成的，且挖掘效率很高；其他的火蚁却什么都不做，故D项正确。5．答案与解析：B词义揣测题。依据第三段第三句中的“whichwouldmaketheconstructionprocessstop”可知，这样的状况可能会使工作停止；结合画线词后的“withinsecttraffic”可知，使工作停止的状况可能是交通堵塞，故B项正确。6．答案与解析：C细微环节理解题。依据第四段第一句“Andwhenthescientistsremovedthefivehardest­workingantsfromthetunnel,othersimmediatelyjumpedintocompensate(补偿)—withnoreductioninthegroup'sproductivity.”可知，当科学家们把五只工作最勤奋的蚂蚁移开时，其他蚂蚁就会立即来补上，组织的生产力没有削减，故C项正确。7．答案与解析：A细微环节理解题。依据尾段的内容尤其是第一句“Thestudycouldprovidesuggestionsfortherobotics.”可知，这一探讨成果可以应用于机器人技术，故A项正确。Ⅱ.完形填空【语篇解读】本文讲了Jane和同伴志愿捡垃圾的活动，告知我们要酷爱环境1．答案与解析：B当她的“想法”在准备生活和晚餐安排间摇摆不定时，可知选B。thought“想法”。2．答案与解析：D意外地被妹妹紧急的电话声“打断”了，可知选D。blame“责怪”；frighten“惊吓”；move“移动”；interrupt“打断”。3．答案与解析：A简“发觉”自己和8位生疏人坐在一辆公交车上，可知选A。find“发觉”。4．答案与解析：B捡拾垃圾并且“提升”人
