展示給別人看，運氣就會喪失；而另一些人則認(rèn)為，如果將四葉草送給別人，運氣就會加倍。作者相信分享會增加積極性，找到四葉草并和別人分享的那種親密感才是重要的。1．答案與解析：D細(xì)節(jié)理解題。由第四段中Tome,itwassimple.Thedifferencesintheirshapespoppedout,breakingtheprettypatternoftheconventionalcloverwiththeirthreeperfectleaves.可知，它們形狀的差異會突顯出來，打破了傳統(tǒng)三葉草美麗的形狀。所以作者能辨別三葉草和四葉草的形狀的區(qū)別。2．答案與解析：C推理判斷題。由第三段可以看出作者非常樂于收集四葉草；第五段中介紹了作者在機(jī)場看見一片小的四葉草也會夾在護(hù)照里；在作者眼中，四葉草是她的“treasure”并樂于向丈夫、朋友分享。由此可以判斷出作者對四葉草有著特別的愛。3．答案與解析：A細(xì)節(jié)理解題。由最后一段中Idon'tthinktheyinfluencemylifeanymorethanitdoestoshareanythingalittlespecial—thatmomentaryclosenessbetweenyouandafriendorastranger,asyouallleanintowonderatararefind.判斷出作者認(rèn)為四葉草帶來的親密感才是重要的。4．答案與解析：C主旨大意題。作者通過自己的經(jīng)歷，旨在表達(dá)并不只是四葉草能帶來幸運，找到四葉草并和別人分享的那種親密才是最重要的。故C選項“不只是運氣”為短文的最佳標(biāo)題。B【語篇解讀】文章屬于說明文，介紹了一種長途飛行的蜻蜓Pantalaflavescens。這種蜻蜓冒險長途飛行的原因是它的繁殖需要濕潤的氣候。5．答案與解析：D推理判斷題。根據(jù)第二段內(nèi)容可知，領(lǐng)導(dǎo)這項研究的生物學(xué)家說基因就是證據(jù)。Pantalaflavescens蜻蜓在不同的洲有可能留有后代，才會有相似的基因。反過來，在不同的洲有共同的基因，證明了它們曾飛到過那兒，也就證明了這種蜻蜓是長途飛行者。6．答案與解析：B推理判斷題。根據(jù)第三段中的Thesedragonflieshaveadaptationssuchasincreasedsurfaceareasontheirwingsthatenablethemtousethewindtocarrythem.可知這些蜻蜓適應(yīng)性強(qiáng)，比如翅膀上表面積的增加，使它們能夠利用風(fēng)來飛行。故B項(運用風(fēng)飛行的能力)正確。7．答案與解析：A細(xì)節(jié)理解題。根據(jù)第五段首句中的WetnessisamustforPantalatoreproduce可知這種蜻蜓的繁殖必須要濕潤的
