D【解析】这是一篇夹叙夹议类的文章。作者将钱包落在了公共汽车上，Erin捡到了作者的钱包，在寒冷的黑夜亲自登门归还钱包。作者深受感动。文章叙述了事情的来龙去脉和作者的感受。【16题详解】根据前文的“fear seized m
26、e. My wallet was gone.”可以推知，作者将钱包落在了公共汽车上，而汽车正在开往某个作者未知的地方，这使得找回钱包的希望渺茫，因此作者心生“恐惧”。故C选项(unknown)切题。【17题详解】根据上一段中的“fear seized me”可以推知，作者在发现丢了钱包之后的第一感觉是“害怕”。之后，作者开始在内心计算找回钱包里的那些东西所需要的时间和钱数。故该空应和fear表达的意思相近，D选项（heart-stopping）切题：令人心跳停止的，惊心动魄的。【18题详解】该空指下文中提到的“the credit cards， the drivers license, the
27、 cash”，这些都是钱包里装的东西。故选B(content)：所含之物，所容纳之物。【19题详解】两小时后有人敲门，丈夫去应门。B选项（answer）切题：应（门）；接（电话）；应答。20题详解】结合下文的陈述可知，那位女士捡到了作者的钱包，她拾金不昧，将钱包完璧归赵。由此可以推知，该处指“钱包里的钱一分也没有丢失”。故A选项（missing）切题：不见的，丢失的。【21题详解】作者甚至还没有来得及到门口感谢那位女士，她就离开了。该空表示“甚至”，故选D选项（even）：甚至。【22题详解】在网上分享了这个故事之后，作者收到了某个人的来信，这个人确认了那位女士是Erin Smith。C选项(
28、identify)切题：确认，认出，识别。【23题详解】找到了那位拾金不昧的女士，作者当然要“马上，毫不耽搁地”打电话去感谢对方。A选项（delay）切题：耽搁，延迟。【24题详解】作者将钱包落在了公共汽车上，Erin是在一个座位上发现了它。该空表示“发现”，故选D选项(spot)：发现，认出。【25题详解】根据文章最后一段中的“a bitterly cold night”可知，这件事发生在一个寒冷的晚上。同时，Erin又不认识作者。由此推知，该句应指：Erin估计去一个陌生人的家是一个冒险的举动。C选项（calculate）正确：估算，估计，预料。【26题详解】根据下文中的转折词but可知，
29、该句和she decided to take the chance（她决定冒险）是转折关系。那么该句应指去一个陌生人家是一个冒险的举动。故B选项（risky）正确：冒险的。【27题详解】该句叙述的是Erin当时的想法：“如果我处在那种情况下（指丢了钱包这种情形），我希望有个人努力地找到我”。该空表示“情况，情形”，故选C选项（situation）：情况，情形。【28题详解】作者丢了钱包，对于作者来说，这是一个“危机，危难时刻”。故选A选项（crisis）：危机，危难时刻。【29题详解】Erin捡到了作者的钱包，在归还作者之前，钱包在Erin的手里，Erin暂时“拥有，占有”作者的钱包。故D选项
30、正确。take possession of意为“拥有，占有”。【30题详解】Erin把作者的驾照图片发到一个论坛里，想看看是否有人认识作者。该空表示“是否”，故选A选项（if）：是否。【31题详解】根据后面的转折词but可知，该句和后面一句（她们想帮忙）转折关系，由此推知，该句指：除了闲聊，作者和那两位妈妈从来没有说过话，即：从未和她们“交换过词语”。B选项（exchange）正确：交换，互换。【32题详解】作者曾经读到这样的说法：人们比以往更加四分五裂，即：人们不像以前那样团结，不像以前那样互相帮助了。但是，作者遇到的这些人的行为方式不是那样的。上文中提到的Erin，two moms都是作者
31、遇到的人。故A选项（encounter）正确：偶遇，遇到，邂逅。【33题详解】回顾发生的这件事，作者感到很幸运：有人想帮助一个陌生人。C选项（look back）正确：回顾，追忆。【34题详解】根据倒数第二段中提到的“people are more divided”可以推知，一般人在捡到别人的钱包后，都不会像Erin那样亲自归还失主。因此该句指：Erin的所作所为远远超越了其他人的行为。该空表示“超过，超越”，故选D选项（beyond）：超过，超越。【35题详解】Erin在寒冷的黑夜亲自登门归还作者的钱包，作者对此非常感激。D选项（grateful）正确：感激的。第二部分：阅读理解（共20小题
32、；每小题2. 5分，满分50分）阅读下列短文，从每题所给的A、B、C、D国个选项中，选出最佳选项。AHistory Fair CompetitionUnderstanding history is vital to understanding ourselves as a people and as a nation.History is much more than the study of dusty old objects and events long past.

62、 numbers of a single prey（猎物），the two species are strongly linked；when a predator lives on various species，they are weakly linked. Food webs may be dominated by many weak links because that arrangement is more stable over the long term. If a predator can eat several species，it can survive the extinc
