odfigure.”（根据女子运动基金会的说法，参加运动的女孩不只是身材好。）同时结合下文讲的是五个原因。所以，设空处和上文为承接关系，是过渡句，可以表述为事实上有五个原因。选项D.“Infact,thereareatleast5morereasons.”（事实上，至少还有5个原因。）切题。5morereasons呼应下文的各个小标题。故选D项。2.根据上文“Girlswhoplaysportsdobetterinschool.Youmightthinkthatplayingsportswilltakeupallyourstudytime.”（做运动的女孩在学校表现更好。你可能认为做运动会占用你所有的学习时间。）下文“Exerciseimproveslearning,memory,andconcentration,whichcangiveactivegirlsanadvantageintheclassroom.”（锻炼可以提高学习能力、记忆力和注意力，这可以让活跃的女孩在课堂上占有优势。）说明了锻炼给女孩带来的好处，所以空白处和上文为转折关系，表明锻炼会给女孩带来好处的。G项“Butresearchshowsgirlswhoplaysportsdobetterinschoolthanthosewhodon’t.”（但研究表明，参加体育运动的女孩比不参加体育运动的女孩在学校表现更好。）该项中的But表示转折关系，故选G项。3.根据本段主题句“Girlswhoplaysportslearnteamworkandgoal-settingskills.”(参加体育运动的女孩能学习团队合作和目标设定技巧。)下文“Whenyouworkwithcoaches,trainers,andteammatestowingamesandachievegoals,you’relearninghowbesuccessful.”（当你与教练和队友一起赢得比赛并实现目标时，你就在学习如何成功。）讲的是体育运动能传授有价值的生活技巧。因而设空处应总说体育运动可以传授一些生活技巧。B项”Sportsteachvaluablelifeskills.”(运动会教会有用的生活技巧。)符合本段文意，故选B项。4.根据上文“Playingsportsimprovesself-confidence.”（做运动可以增强自信。）所以接下来讲述做运动对女孩的好处，E项“Girlswhoplaysportsfeelbetteraboutthemselves.”（喜欢运动的女孩自我感觉更好。）切题。故选E项。5.本句作为段落主题句，结合上文提到的内容，本段同样讲述做运动可以带来好处。根据下文“Playingsportscanreducestressandhelpyoufeelalittlehappier.”（运动可以减少压力，帮助你感觉更快乐。）所以，空白处讲述运动可以减少压力。A项“Exercisecutsthepressure.”（运动减少压力）切题。故选A项。16、C牝17、A牝18、F牝19、G牝20、E【导语】这是一篇说明文。主要介绍了家庭园艺的好处。牝16、上文“Evenbetter,youdon’thavetowaitforyourplantstoflowertoseethebenefits.（更妙的是，你不必等待你的植物开花才能看到好处。）”说明你可以很快看到好处，C项中them指代前句中的benefits，C项“其中一些就在那里让你享受”进一步说明家庭园艺的一些好处不需要等待，符合题意。故选C项。牝17、下文“Gardeningandyardworkarelightexercises（园艺和庭院工作是轻松的运动）”以及“Gardeningcanhelpreducestressforsomefascinatingreasons（由于一些有趣的原因，园艺有助于减轻压力）”可知，家庭园艺可以使身体动起来，还能缓解压力，A项“更多的体育活动和较少的压力”可以作为本段标题句，强调身体活动与较少的压力，符合题意。故选A项。牝18、下文“Andbettersleep,inturn,canimprovekids’behaviorandperformanceatschool.（而更好的睡眠反过来可以改善孩子们在学校的行为和表现。）”说明更好的睡眠的好处，F项moreandbettersleep是关键词，F项“以上好处有助于每个人获得更多更好的睡眠”说明上文提到的好处可以获得更好的睡眠，符合题意。故选F项。牝19、上文“Childrenlikespendingalotoftimeindoors,whichcannegativelyaffecttheirbehaviorandhealth.（孩子们喜欢在室内待很长时间，这会对他们的行为和健康产生负面影响。）”说明长时间待在家里会对孩子产生负面影响，G项“家庭园艺让他们在户外享受和体验自然世界。”说明家庭园艺能让孩子去户外体验自然，符合题意。故选G项。牝20、上文“Gardeninghelpsteachkidsresponsibility.（园艺有助于培养孩子的责任感。）”说明园艺有助于培养孩子的责任感，E项“他们可以为你的家庭花园做很多工作”说明孩子们可以承担的责任，符合题意。故选E项。21、F牝22、A牝23、E牝24、D牝25、G【导语】本文是一篇说明文。文章介绍卡通片的制作过程。牝21、根据上文提示“ToyStory,Cars,FindingNemo,Wall-E,Up—youhaveprobablywatchedallthesefilms.（《玩具总动员》、《汽车总动员》、《海底总动员》、《机器人总动员》、《飞屋环游记》——这些电影你可能都看过）”，再根据下文提示“Let’sgothroughtheprocessofcreatingacartoonfilm.（让我们来看看制作卡通电影的过程）”，可知，根据常识，人们一定想知道这些卡通是怎样制作出来的，接下来空后引出这个话题。所以F项Haveyoueverwonderedhowtheseamazingcartoonfilmsweremade?（你有没有想过这些神奇的卡通电影是如何制作出来的?）符合上下文连贯，该项中的howtheseamazingcartoonfilmsweremade吻合了theprocessofcreatingacartoonfilm。故选F项。牝22、根据上文提示“Thefirststepistowritedownthemainideasofthestory.（第一步是写下故事的主要思想）”，再根据下文提示“Basedonthestoryboard,theartdepartmentcreatesthefirstdraftforthecharacters,theirclothingandemotions,andthedesignsets.（根据故事板，美术部门为角色，他们的服装和情绪，以及设计布景创造了初稿）”，可知，由初稿绘制出故事板。所以A项Fromthat,storyboardsaredrawn.（由此，故事板被绘制出来）符合上下文连贯，该项中的that指代上文中的themainideas，storyboards与下文的Basedonthestoryboard吻合。故选A项。牝23、根据上文提示“Aspecialcomputerprogramisusedtocreate3Dshapesofthecharacters,setsandprops—thisi
