24、ndsBhandsCspiritsDeyes【语篇解读】本文是一篇记叙文。主要讲述了一个六岁的男孩失去父母后通过赠送玩具的方法来收集人们的微笑，使自己和他人摆脱悲伤的故事。1B根据空后“ then last month his mom died unexpectedly, _2_ him an orphan (孤儿)”可知，此处指他四岁时“失去”了爸爸。2B上文提到Jaden Hayes遭遇两次梦魇，父母相继去世，所以此处指“成为”孤儿，“leavesb.宾补”结构中，名词作宾补时，意为“使某人成为”。3D上一句提到“Jaden is understandably heartbroken.”，
25、所以此处指他的“悲伤”，下一句中“he was tired of seeing some people sad all the time”也是提示。4C根据“when he told his friends”可知，此处指“公开的”。5A根据“he was tired of seeing some people sad all the time”可知，他有了“解决”这个问题的计划。6A根据下文他的具体行动可知，此处指他的计划如何“开始”。7B根据下文“Sometimes it simply confuses some people _11_ a sixyearold would give the
26、m a toy.”可知，他请求姑姑给他买一些“玩具”。8C根据“then turns their day around”可知，他的“目标”是那些没有笑容的人，然后改变他们的一天。9D根据“but a smile”可知，Jaden不求什么回报，只想要个微笑。10D根据上文“expecting _9_ in return but a smile”可知，Jaden的目的是想要微笑，所以此处指目前已经“收集”了近500个微笑。11A根据“it simply confuses some people”可知，人们不知道这个六岁的男孩“为什么”要给他们玩具，所以感到困惑。12C根据“They behaved
27、 awkwardly at first: stepping back”可知，人们一开始表现得很拘谨，后退或者露出“生硬的”微笑。13A根据上文内容可知，他厌倦了看到人们悲伤，所以这个计划的目的是让人们微笑，所以此处指“快乐”，文章最后一句“there is always some measure of joy”也是提示。14B根据上文可知，Jaden父母都去世。所以此处指每一天都会“想念”父母。15C根据上文“he was tired of seeing some people sad all the time”并结合本句“He puts smiles back on the face of
28、others”可知，他厌倦看到人们悲伤，让人们重拾微笑，以振奋他们的“精神”。.语法填空As I went through school, I came to understand that life was about 1._(compete). The only thing that mattered was doing 2._(well) than everyone else.

34、哥， 而是坚持做让自己感到快乐的事情。1competition考查词性转化。 句意： 上学的过程中， 我逐渐理解了生活就是竞争。故填名词competition。2better考查比较级。句意： 唯一重要的事情就是比别人做得更好。根据空后than以及句意可知应填比较级better。3awards考查名词的数。句意： 我看着他们一次又一次获奖。award(奖励)是可数名词， 前面没有冠词， 结合后面 “time and time again”可知用复数形式awards。4with考查介词。句意：但是随后我了解到我不能在这件事上与我的兄弟和其他人竞争。 compete with sb. “与某人竞争
35、”。故填with。5thinking考查现在分词。句意：想起为了领先所有人不得不在学习和工作中投入的时间， 我肚子就会疼。分词作状语， 与句子主语“I”为主动关系， 故填thinking。6what考查连接词。句意：我决定去做能给我带来快乐的事。此处为宾语从句， 从句中缺少主语，故填连接词what。7to afford考查不定式。句意： 与此同时， 他们挣了很多钱， 能够买得起昂贵的车， 能够享受似乎愉快的旅行， 但是我决定不拿带给我快乐的工作与豪车、旅行做交易。be able to do是固定搭配。故填to afford。8that/which考查关系代词。此处为限制性定语从句， 先行词是job, 故填which或that。9majored考查谓语动词。句意：我在大学主修英语专业同时专注于创作小说。由语境可知作者在回忆过往， 需用一般过去时， 故填majored。10while/though考查连词。句意： 而且其他出乎预料的方面是： 虽然我从没有挣到很多钱， 但是我也有了自己的车， 而且很幸运有一些非常棒的工作旅行。由语境可知此处表让步，故填while/though。
