22、nethoughtitwasjustacleverAprilFoolstrick”可知,在刚开始时,人们认为创办这个节目只是一个愚人节玩笑,可见人们没有把它当回事。故选B项。3答案与解析:D细节理解题。根据第三段的“Stocksayshewasinspiredtocreatethespecialprogrammebyhispetdog, Layla.”可知,施托克创建这个节目是源于他在自己的生活经历中受到的启发。故选D项。4答案与解析:A推理判断题。根据最后一段的“theprogrammecanalsobeaccessedonlinehere.Justpresstheplayarrowatth
23、etopofthepageandletthemusicworkitsmagic”可推知,这篇短文最可能来自于网页。故选A项。B【语篇解读】本文是一篇说明文。经过艰难的研究攻关,中国科学院取得重大突破,在国际上首次实现了非人灵长类动物的体细胞克隆。中中和华华成为世界上首对克隆猴。5答案与解析:C细节理解题。由第一段的“ZhongzhongandHuahualookjustthesameasanyothermonkey.Buttheyhappentobetheworldsfirstclonedmonkeys.”可知,中中和华华是世界上首对克隆猴。故选C项。6答案与解析:B细节理解题。由倒数第三段第

25、“Monkeysandhumansarecloselyrelatedandtestingonmonkeysissupposedtobeaseffectiveastestingonhumans”可知猴子和人类比较接近,且人们认为对猴子的实验和对人类的实验一样有效,所以科学家想用猴子做药物实验。故选D项。.完形填空【语篇解读】本文是一篇夹叙夹议文。作者讲述了参加“PeertoPeer”志愿者组织的经历和收获。1答案与解析:D根据下文的“byaposter”可知,一幅海报让作者知道了“PeertoPeer”这个当地志愿者组织,因此该空用introduced“使初次了解”。2答案与解析:B根据第三段的
26、“Thisorganizationsmeetings”可知,此处指作者参加志愿者组织的一次会议(meeting)。3答案与解析:A根据第一段的“PeertoPeer”和空后的“everyoneisconsideredapeer”可知,此处表示正如这个志愿者组织的名字表明的那样,这里的每个人都被认为是同龄人,因此该空用name。4答案与解析:A根据本句中的“bytheirfirstnames”可知,作者他们直呼领导们的名字。address在此是及物动词,表示“称呼(某人)”。5答案与解析:B由句中的“askourleadersforhelp”可知,在生活中有困难时可以向领导们求助,并且领导们从不
27、拒绝,因此该空用difficult。6答案与解析:D参见上题解析。reject表示“拒绝,不予考虑”。7答案与解析:B由句意可知,志愿者组织的会议在图书馆召开,因此该空用takeplace“进行”。carryon“继续,参与”;setdown“制定”;turnup“到达,突然出现”。8答案与解析:C下文谈到的“education,equalityandsafety”是社会热门话题,因此该空用hot“热门的”。9答案与解析:A这种交流帮助作者他们作出正确的选择,开阔他们的眼界,因此该空用broaden“增长(经验、知识)等”。10答案与解析:D根据下文提到的“GiveacigaretteTake
28、acandy”可知,作者参加的是一些有意义的活动,因此该空用meaningful“有意义的”。11答案与解析:C根据活动的主题“GiveacigaretteTakeacandy”可知,用香烟换糖,其目的当然是鼓励人们少吸烟。故C项decrease“减少”符合语境。12答案与解析:B由上文的“Atthisorganizationwearefriendswitheachother”可知,在这里作者他们彼此是朋友,此处应表示他们是一个亲密的团体,因此该空用tight“亲密的,密切的”。13答案与解析:B作者参加的这些志愿者组织确保自己有发展个性的绝好机会,因此该空用guaranteed“确保,保证”。14答案与解析:D根据全文的感情色彩和第一段中的“whichchangedmylife”可知,参加志愿者组织使作者的生活发生了巨大变化,因此此处指“让我的人生好得令人难以置信”。D项“非常好的,令人难以置信的”符合语境。15答案与解析:A作者相信随着年龄的增长,自己会有很多与青春有关的美好回忆(memories)。
