40、.”可知，救助受伤、生病的动物有时令人悲伤，因为不能保证救助的动物能活下来，即努力可能会白费。2答案与解析：C细节理解题。根据第二段中的“I got a rescue call from a woman in Muttontown. She had found a young owl on the ground. When I arrived, I saw a 2to 3weekold owl.”可知，有人给作者打电话是因为在地上发现了一只猫头鹰幼雏，作者赶过去看看情况。文中并没有说猫头鹰幼雏是否受伤，所以作者不是去救治幼雏。3答案与解析：B推理判断题。根据文章内容可知，作者为猫头鹰幼雏做了窝
41、，并且帮助它找回了它的父母。猫头鹰幼雏的父母还为它带回了午餐。作者的救助成功了，结局是美好的。再结合第一段的“However, when it works, it is simply beautiful.”可推测，作者对猫头鹰幼雏的救助成功了，因此作者对于这个结果感觉很美好。B【语篇解读】这是一篇说明文。犯罪每天都在发生，但人们并不是非法活动的唯一受害者，还有动物。然而动物不能告诉警察他们遭受了什么，因此这些都是最难解决的案件。偷猎者通过出售肉类、皮毛和其他受保护动物的身体部位可以赚很多钱。如今警方通过检测血液或头发中的DNA可以识别出罪犯和受害动物。4答案与解析：D细节理解题。根据第二段第三
42、句“So poachers earn even greater rewards for their collection of protected species.(偷猎者通过偷猎受保护动物来获取更多的利润。)”可知，作者举出象牙的例子是为了说明偷猎者从他们的非法活动中获得了巨大的利润。故选D项。5答案与解析：D推理判断题。根据最后一段中的“If the worlds poaching victims could talk, they would probably thank these scientists for their work.(如果全世界的偷猎受害动物都能说话，他们可能会感谢这些
43、科学家的工作。)”可知，作者对科学家们的工作是欣赏的。故选D项。6答案与解析：D推理判断题。根据第三段中的“Like fingerprints, DNA is unique to every person. So by examining DNA in blood or hair, the police can recognise criminals and victims.(就像指纹一样，DNA对每个人来说都是独一无二的。因此，通过检测血液或头发中的DNA，警察可以识别罪犯和受害动物。)”可知，第三段主要解释了DNA是如何帮助警方识别罪犯的。故选D项。7答案与解析：C细节理解题。根据第四段第
44、一句“When the police find poached animal parts, such as their fur or bones, it is difficult to know what species the victims are, which is mostly cared about.(当警方发现被偷猎动物的皮毛或骨头等部位时，很难知道受害动物是什么物种，而这是最受关注的部分。)”可知，当警察发现被偷猎动物的身体部位时，他们想知道的第一件事是它们属于什么物种。故选C项。.七选五【语篇解读】这是一篇说明文。文章主要介绍了我们可以从大自然中学到的一些东西，比如享受阳光。1
45、答案与解析：A根据上文“Look at how each plant plays a part in the loving whole.(看看每一株植物是如何在爱的整体中扮演一个角色的。)”可知，此处是将植物比喻成人类，像我们每个人一样。故选A项。2答案与解析：G根据上文“But a huge part of nature is learning how to be uprooted and blossom wherever you are.(但是，大自然的一个重要部分是，无论你身在何处，都要学会如何被连根拔起并开花结果。)”可知，你可以生根一次或多次。故选G项。3答案与解析：C根据下文“Ge
46、t outside and experience all the joys of beautiful sunshine.(走到户外，感受美丽阳光带来的快乐。)”可知，本段强调我们应该像植物一样，每天都得到阳光。故选C项。4答案与解析：E根据下文“Sometimes they may not grow so fast due to lack of nourishment in some form, but they keep on growing.(有时，由于缺乏某种形式的营养，它们可能长得不那么快，但它们会继续生长。)”可知，本段强调不管发生什么，植物都在继续生长。故选E项。5答案与解析：B根
47、据下文“You are beautiful just by being you, too！(你很美，因为你就是你！)”可知，本段强调自然界的一切都是美丽的。故选B项。.语法填空【语篇解读】本文为记叙文。作者叙述了自己在西安旅行的一段经历。作者通过去西安参加一个培训课程的经历，增加了对中国文化的了解，感叹文化是不分国界和种族的。1答案与解析：ladies考查名词复数。由ladies前的数词two，可知，此处是可数名词的复数形式。故填ladies。2答案与解析：felt考查谓语动词的时态。句意：我一下了飞机，就感觉到气氛发生了变化。根据从句时态提示词landed，可知主句也应用一般过去时，故填fe
48、lt。3答案与解析：waiting考查非谓语动词。句意：我看见人们在入境服务台排队等候。此处为“see宾语宾补”复合结构，see sb. doing sth.为固定搭配，意为“看见某人在做某事”，故填waiting。4答案与解析：from考查介词。句意：中国邀请了来自23个发展中国家的代表与他们分享数字电视广播技术。根据语境可知，此处是指“来自”，from意为“来自”，故填介词from。5答案与解析：to observe考查非谓语动词。get an opportunity to do sth.得到一个做某事的机会。6答案与解析：and考查连词。句意：在西安的20天里，我有机会仔细观察中国文化，
49、而且这还给我留下了难忘的印象。分析上下文语境可知，此处是两个并列句，且是递进关系，故填and。7答案与解析：badly考查副词。句意：我一直非常想念西安。分析句子可知，本空格在句中修饰动词miss。修饰动词要用副词，bad为形容词，故填badly。8答案与解析：a考查不定冠词。句意：我在西安的20天是一次很好的经历。experience作“经历”讲时，是可数名词，此处是指一次经历，要用不定冠词a表示数量“一”，也是泛指。故填a。9答案与解析：are tied考查动词。句意：尽管有不同的肤色、身高、种族和宗教，但所有人都被人道的纽带紧紧连在一起。分析句子可知，主语human beings与谓语动词tie之间为被动关系，要用被动语态。根据后一句的时态可知要用一般现在时，且主语是复数，故填are tied。10答案与解析：development考查词性转换。作介词的宾语应当用名词形式。
