I just saw them.I spent my childhood collecting and pressing fourleaf clovers into books at my mothers house. I started with big cloth and leatherbound books. Whe
3、n I ran out of romantically bound volumes, I began to put my treasures into anything I could find: fiction paperbacks and cookbooks. The same is true in my house today. Shake a book, and a papery treasure just might fall into your hand.A few years ago, in Nova Scotia, my husband and I pulled off the
4、 road for a picnic. The ground was thick with clover. Some shoots had four, five, even six leaves. I lined them up on the picnic table to admire as my husband, never yet having found one fourleaf clover, looked on in awe. To me, it was simple. The differences in their shapes popped out, breaking the
5、 pretty pattern of the conventional clover with their three perfect leaves.Two summers back, while waiting for an airport shuttle in Munich, I found a tiny fourleaf clover in a traffic circle and put it into my passport. On the way home, my husband and I were upgraded to business class. Friends attr
6、ibuted our good luck to the clover. I think, its more likely that we were upgraded because a kind customer service officer took pity on us.People disagree about whether the luck lies in the finding or in the possession of a fourleaf clover. Some believe that the luck is lost if the fourleaf clover i
7、s even shown to somebody else, while others think the luck doubles if it is given away. I believe that positivity is increased by sharing. I feel lucky to find the clovers so often, but I dont think they influence my life any more than it does to share anything a little specialthat momentary closene

11、e travelerflying thousands of miles over oceans as it migrates from continent to continentaccording to a newly published research.Biologists who led the study say the evidence is in the genes. They found that populations of this dragonfly, called Pantala flavescens, in Texas, eastern Canada, Japan,
12、Korea, India, and South America, have genes so similar that there is only one likely explanation. Apparentlysomehowthese insects are traveling distances that are extraordinarily long for their small size, breeding (繁殖) with each other, and creating a common worldwide gene pool.But how do insects fro
13、m different continents manage to meet and hook up? Ware says it appears to be the way their bodies have evolved. “These dragonflies have adaptations such as increased surface areas on their wings that enable them to use the wind to carry them.”Dragonflies, in fact, have already been observed crossin

15、duce, and that , says Ware, is why these insects would be driven to even attempt such a dangerous trip, which she calls a “kind of suicide.” The species depends on it. While many will die on the route, as long as enough make it, the species survives.For the moment, the details of this extraordinary
16、insect travel are a best educated guess. Much more work is needed to bring many loose ends together. Ware and Troast hope that scientists can work on plotting those routes.5What proves Pantala flavescens are the worlds longestdistance flyers?AScientists have tracked the dragonfly across the world.BT

24、集四叶草，并能够比别人更容易地找出四叶草。有些人认为，如果四叶草被展示给别人看，运气就会丧失；而另一些人则认为，如果将四叶草送给别人，运气就会加倍。作者相信分享会增加积极性，找到四叶草并和别人分享的那种亲密感才是重要的。1答案与解析：D细节理解题。由第四段中To me, it was simple. The differences in their shapes popped out, breaking the pretty pattern of the conventional clover with their three perfect leaves.可知，它们形状的差异会突显出来，打破
25、了传统三叶草美丽的形状。所以作者能辨别三叶草和四叶草的形状的区别。2答案与解析：C推理判断题。由第三段可以看出作者非常乐于收集四叶草；第五段中介绍了作者在机场看见一片小的四叶草也会夹在护照里；在作者眼中，四叶草是她的“treasure”并乐于向丈夫、朋友分享。由此可以判断出作者对四叶草有着特别的爱。3答案与解析：A细节理解题。由最后一段中I dont think they influence my life any more than it does to share anything a little specialthat momentary closeness between you a
26、nd a friend or a stranger, as you all lean in to wonder at a rare find.判断出作者认为四叶草带来的亲密感才是重要的。4答案与解析：C主旨大意题。作者通过自己的经历，旨在表达并不只是四叶草能带来幸运，找到四叶草并和别人分享的那种亲密才是最重要的。故C选项“不只是运气”为短文的最佳标题。B【语篇解读】文章属于说明文，介绍了一种长途飞行的蜻蜓Pantala flavescens。这种蜻蜓冒险长途飞行的原因是它的繁殖需要湿润的气候。5答案与解析：D推理判断题。根据第二段内容可知，领导这项研究的生物学家说基因就是证据。Pantala
27、flavescens蜻蜓在不同的洲有可能留有后代，才会有相似的基因。反过来，在不同的洲有共同的基因，证明了它们曾飞到过那儿，也就证明了这种蜻蜓是长途飞行者。6答案与解析：B推理判断题。根据第三段中的These dragonflies have adaptations such as increased surface areas on their wings that enable them to use the wind to carry them.可知这些蜻蜓适应性强，比如翅膀上表面积的增加，使它们能够利用风来飞行。故B项(运用风飞行的能力)正确。7答案与解析：A细节理解题。根据第五段首句
28、中的Wetness is a must for Pantala to reproduce可知这种蜻蜓的繁殖必须要湿润的气候。10答案与解析：D推理判断题。根据第五段内容可知，对于这种昆虫来说，这种危险的旅行是自杀式行为。虽然许多昆虫会死在途中，但这种物种依靠这种旅行生存下来。从后面一句While many will die on the route, as long as enough make it, the species survives.可知，it指的是上文的危险旅行。.七选五【语篇解读】文章属于说明文。介绍了一本美国畅销书谁动了我的奶酪。1答案与解析：D前文提到“谁动了我的奶酪讲述了
29、一个发生在老鼠和人之间的故事。”是该书的内容简介，D选项“该书的作者斯宾塞约翰逊专为青少年写了这本书。”为作者的介绍，与前文对应。故选D项。2答案与解析：B前文提到“这本书告诉我们，当我们面对生活中的变化时，比如新学校或新朋友，不要害怕”，B项“相反，利用这些变化来创造更好的生活。”与前文的内容衔接自然，“changes”与前文呼应。故选B项。3答案与解析：F前文提到“在这里，奶酪意味着生活中重要的事情，比如搬到一个新的班级或进入大学。”指生活中出现了新变化，奶酪自然就不见了，后文又提到“必须找到更多的奶酪”。F项“但是他们发现奶酪不见了。”承上启下。故选F项。4答案与解析：G上句提到“小矮人做不到这个”，G项“他们害怕变化，所以找不到奶酪。”解释前句小矮人找不到奶酪的原因。故选G项。5答案与解析：E根据设空处前文可知，此处总结文章主旨，结合全文的启示，在生活中遇到变化时，我们需要快速融入环境。E项“为了得到更多的奶酪，快速地朝新的方向前进。”与文章的主旨相对应。故选E项。
