答案以及解析一、答案：1-3BAC

解析：1.细节理解题。根据Visitanationalpark部分中的“Ifyou’reupforachallenge,youcanclimbtheHalfDomeinYosemiteorracedownthegreatsanddunesinColorado.”可知,如果你准备迎接挑战,你可以去爬约塞米蒂国家公园的半圆山,或者冲下科罗拉多的沙丘。由此可知,寻求刺激的人最可能选择参观国家公园。故选B。

2.细节理解题。根据文章中对四个度假计划中的“affordable;cheap;Itdoesn’tcostmuchmorethancamping.”可知,这四个度假计划都不贵,而Wallet-friendly的意思就是省钱。故选A。

3.细节理解题。根据RentanRV部分中的“UsinganRVforavacationmeansyou'repayingforyourtransportationandlodgingallinone.”可知,用房车度假意味着付一次款可以同时解决交通与住宿两个问题,而killtwobirdswithonestone意思是“一箭双雕”,符合题意。故选C。二、答案：4-7DBAC

三、答案：8-11DABD

解析：8.细节理解题。根据第一段中ForshopaholicsintheUK,theplacetoheadtousedtobethe"highstreet".Thislocationreferstothestreetsinthecentreofatownwherebusinessesandpopularbranchesofretailchainscouldbefound.(对于英国购物狂来说,过去应该去的地方是'highstreet"。这个位置指的是城镇中心的街道,在那里可以找到商业和流行的零售连锁店的分支机构。)可知,"highstreet"是指有许多商业的城镇的主要街道。故选D。

9.词义猜测题。根据画线词后文"Newsaboutshopslosingmoneyandshuttingisnowcommon.Somecity-centredepartmentstoreshaveclosedandevenlong-establishedretailerssuchasMarksandSpencerhavereportedprofitslumps(商店亏损关门的新闻现在很普遍。市中心的一些百货商店已经关闭,甚至像玛莎百货这样历史悠久的零售商也宣布利润下滑)可知画线部分所在句意思为:我们购物习惯的改变已经对英国的商业街造成了不好的影响。画线词意思为"造成不好的影响"。故选A。

10.细节理解题。根据第四段Butthebiggestthreathascomefromonlineshopping.Shesays,"Consumersnowspendoneineveryfivepoundsonline-andifbusinessesareseeing20percentfewersalesontheshopfloor,thenprofitmarginswillbesqueezed.(但最大的威胁来自网购。她说:"消费者现在每五英镑中就有一英镑是在网上消费的如果商家看到商店里的销售额减少20%,那么利润率就会受到挤压。)可知,传统零售业衰落的主要原因是网上购物。故选B。

11.细节理解题。根据最后一段中Meanwhile,backonthehighstreet,someshopsstillexist.Analystshavesaidit'sthosethathavemovedawayfromtraditionalretailingthataresurviving.Theseincludebeautysalons,nailbarsandindependentcoffeeshops-butarethesekindsofshopsenoughtokeeptheBritishhighstreetopenforbusiness?(分析人士表示,那些脱离传统零售业的公司才能生存下来。这些商店包括美容院、美甲店和独立咖啡店但是这些商店足以让英国商业街保持营业吗?)可知,美容院和美甲吧能在商业街上生存下来。故选D。这是一篇日常生活类阅读理解。文章主要介绍了英国的购物现状,因为受到人们购物习惯的改变,许多商业街上的实体店铺亏损关门的新闻变得很普遍。文章介绍了产生这一现象的原因以及影响。四、答案：12-15BBAC

解析：1.细节理解题。根据第一段的第四句Giventherighttools,wecantrainourbrainstoactliketheydidwhenwewereyounger可知,只要有合适的工具,我们就能把大脑训练得像年轻时一样。即我们的大脑可以被训练得敏捷。

2.细节理解题。根据第二段的第三句theprogramstartsaskingyoutodistinguishsounds(between“dog”and“bog”,forinstance)atanincreasinglyfasterrate可知,程序开始要求你以越来越快的速度分辨声音(例如“dog”和“bog”)。这两个词发音接近。

3.细节理解题。根据最后一段的第三句Anditmayspeedupintheprocess可知,大脑的学习过程会变得越来越快。

4.推理判断题。根据最后一段第四句的内容可知,让你的大脑保持年轻,你可以做一百万个用来训练大脑活动中的任何一个:打乒乓球、打牌、做游戏、学习一门新语言或者舞蹈、学钢琴、制作模型飞机、掌握园艺技术、发现啤酒酿造的秘密、还有学习高等数学。五、答案：16-20EFABG解析：这是一篇说明文。不管你有多少经验,在出发前让大家回顾一下划船安全规则总是一个好主意。文章主要介绍了一些可以确保安全的基本的划船安全提示。16.根据上文“Alwayschecklocalweatherconditionsbeforedeparture.(出发前一定要查看当地天气情况)”可知,上文提到出发前查看当地天气情况,可知本句应承接上文列举天气预报的信息来源,故E选项“电视和广播预报是一个很好的信息来源”符合语境,故选E。17.根据后文“Followingapre-departurechecklististhebestwaytomakesurenoboatingsafetyrulesorprecautionshavebeenoverlookedorforgotten.(要确保没有忽视或忘记任何划船安全规则或预防措施,最好的办法是在出发前检查清单)”可知,后文提到了划船前检查清单,即为划船做好准备,F选项中boatingsafety对应后文中boatingsafety。故F选项“正确的划船安全包括为任何水上可能发生的情况做好准备”符合语境,故选F。18.根据上文“Oneofthemostimportantpartsofboatingsafetyistouseyourcommonsense.(划船安全最重要的部分之一就是运用你的常识)”以及后文“Youshouldoperateatasafespeedatalltimes(especiallyincrowdedareas),staycautiousatalltimesandsteerclearoflargevesselsandwatercraftthatcanberestrictedintheirabilitytostoporturn.Also,berespectfulofbuoysandothernavigationalaids,allofwhichhavebeenplacedtheretoensureyourownsafety.(在任何时候都应该以安全的速度操作,特别是在拥挤的地方,时刻保持谨慎,避开大型船只和船只,因为它们可能会限制它们的停车或转弯能力。同时,请尊重浮标和其他导航设备,所有这些都是为了确保您的安全而设置的)”可知,上文提到了运用常识很重要,后文则举出了具体的例子,可知本句承接上文再次强调运用常识的重要性。故A选项“这意义重大”符合语境,故选A。19.根据本段内容“Makesuremorethanonepersononboardisfamiliarwithallaspectsofyourboat'shandling,operations,andgeneralboatingsafety.Iftheprimarynavigatorisinjuredinanyway,it'simportanttomakesuresomeoneelsecanfollowtheproperboatingsafetyrulestogeteveryoneelsebacktoshore.(确保船上至少有一人熟悉船舶的操作和一般划船安全的各个方面。如果主领航员以某种方式受伤,确保其他人能够遵循适当的划船安全规则,将其他人带回到岸上是很重要的)”可知,后文提到确保船上至少有一人熟悉船舶的操作,以及主领航员的情况,说明除了主领航员外,要有一名助理船长辅助。故B选项“选一名助理船长”符合语境,故选B。20.根据上文“Whetheryouchoosetoinformafamilymemberorstaffatyourlocal
