本文是一篇科普说明文。文章讲述了欧洲科学家研究了作为哺乳动物的蝙蝠寿命长的原因。同时列举了几种不同蝙蝠寿命长的原因。1.C推理判断题。根据短文内容“Scientistsbelievethisshorteningprocesscausescellstobreakdown.”可知,这个缩短的流程会引起细胞破损,会对寿命造成影响。故选C。2.B细节理解题。根据倒数第二段中“Thescientistsfindingssuggestthatthesebatscellshavetheabilitytokeepandrepairtheirtelomeres.”可知,这些蝙蝠长寿的原因是因为它们的细胞能保持和修复它们的端粒。故选B。3.A代词指代题。根据倒数第二段中“Basedonitsbodysize,abatlikethegreatermouse-earedbatwouldbeexpectedtolivefouryears.”可知,此处that指fouryears。故选A。4.C标题归纳题。本文主要讲述的是科学家研究蝙蝠长寿的原因,C项符合文章主题。故选C。.主旨大意 本文是一篇记叙文,文章主要讲述了一位名叫KyleSchwartz的老师采取措施教育学生的故事。KyleSchwartz为了更好地掌握学生的情况,让学生写出自己想让老师知道的事情,结果导致班风出奇的好,这让她非常惊喜。由此告诉我们:认真聆听别人的心声,才能更好地了解他人。5.C考查形容词辨析。根据第三段中的“Idontwantthemtobepoorforever”可知,KyleSchwartz所教的班级里的大部分学生都来自贫困家庭。故选C。6.B考查名词辨析。根据第三段第一句中的“Somenotesarereallyheartbreaking”可知,KyleSchwartz让每名学生写一张便条。故选B。7.A考查形容词辨析。根据本句中的“gavetheteacherachancetounderstandherstudentsdifficulties.”可知,学生们都实事求是地写出了他们各自的心声,即他们的回答很诚实。honest意为“诚实的”,符合语境。故选A。8.D考查动词辨析。根据下句中的“wroteanother”可推知,“IwishmyteacherknewIhavenopencilstodomyhomework”是其中一个孩子在便条上写的内容。故选D。9.A考查形容词辨析。根据本句中的“sometimesmyreadinghomeworkisnotsigned”可推知,有时候妈妈之所以没有在阅读作业上面签名,是因为她没有空。故选A。10.D考查名词辨析。根据下句“IwishmyteacherknewthatIwanttogotocollege.”可知,上大学是将来的事情,所以此处是在谈论“对未来的希望”。故选D。11.B考查副词词义辨析。根据本句中的“Idontwantthemtobepoorforever”及下句“IhopedtoknowIcouldbettersupportthem.”可推知,KyleSchwartz不想让孩子们永远贫穷,所以她深深地关心着每一个孩子。故选B。12.C考查特殊疑问词辨析。句意:我想知道自己怎样才能更好地支持他们。how意为“如何”。故选C。13.A考查动词辨析。根据上句“Ihopedtoknow Icouldbettersupportthem.”可推知,KyleSchwartz正在寻找帮助并支持孩子们日后发展的方法,所以她决定让孩子们对她说出他们的种种困难。decidetodosth.意为“决定做某事”。故选A。14.B考查连词辨析。“wereallowedtoansweranonymously”与“mostwantedtoincludenames”之间构成了逻辑上的转折关系,所以本句应是让步状语从句。though意为“虽然;尽管”,引导让步状语从句。故选B。15.A考查介词辨析。分析句子结构可知,“oneshygirlwhobravelysaidthatshewaslonely”在此是具体的例子,指这位腼腆的女孩是众多情绪激动的孩子中的一员。like意为“像”,符合语境。故选A。16.D考查动词短语辨析。根据上句中的“shewaslonely”及下文中的“Theyinvitedhertoplay”可推知,这位腼腆的女孩平时很孤独,她没有可以一起玩的朋友。故选D。17.C考查代词辨析。根据下句“Theyinvitedhertoplayatbreakandsitwiththematlunch.”可推知,其他的孩子邀请这位腼腆的女孩和他们一起玩,说明“其他的孩子主动为她提供了许多支持”。此处指代的是shygirl,应用her。故选C。18.A考查名词辨析。结合语境可知,孩子们乐于为他人提供帮助,他们拥有不同寻常的表达同情的能力。故选A。19.B考查形容词辨析。根据第四段内容可知,班里的孩子开始相互提供帮助,他们学会了同情并帮助别人,这种变化出乎KyleSchwartz的意料,让她感到很惊讶。故选B。.20.died21.tosend22.himself23.at24.musicians25.until26.the27.leader28.in29.greatest.30.people31.hundred32.practice33.minutes34.relax35.us36.leave37.follow38.fight39.strict.Onepossibleversion:DearAlice,Asateenager,Imetthesameproblemasyou.ButnowIcangetalongwithmymother.Herearesomeideasforyou.Yourmothertalksmuch,becauseshecaresaboutyou.Maybeitsnotagoodway,butitshowsyourmotherslove.SoIthinkyoushouldlistentoher.Ifyouropinionsaredifferentfromyourmothers,youcanmunicatewithher,andtellherwhatyourethinkingabout.Ifyourmotherdoesnttakeyouradvice,justkeepsilentandgiveherasmile.IhopewhatIsayherecanhelpyou.Yours,Linda
