mom waiting patiently.Tears of happiness blurring my eyes,I took her hand tightly,headinghome【A篇】【本文介绍了Queenztown的四个值得去的条点，】2l.C细节理解题，根据介绍Queenstown Gardens的段落可知，“The Queenstown Gardens Trailis a wheelchair-accessible trail just a few minutes from central Queenstown.”,可知，此景点轮椅可以进入，因此对于残疾人而言，是最佳选择。故选C。22.D细节理解题。根据介绍Arrow River Trail的段落可知l,此处可了解当地历史。但鸟瞰Qucenstown是在Tiki Trail,嗅玫瑰花香是在Qucenstown Gardens,.亲历极限登山是在Ben Lomond Track。故答案为D。23.B主旨题。根据文章首段内容可知，本文主要介绍四个景点相关信息，故答案为B。【B篇】【文章简单介绍了一本书Li,书中作者将人与锡罐、游泳池、蹈菇和服狗等进行比较，揭示出作为“人”的我们，具有独有的特征。】24.C猜词题。根据第一段“The opening spread establishes a somewhat odd yet matter--of-facttoC.”,可知，书的开头一章，叙述方式有些不寻常，结合本句后面作者将人与锡罐比较，以此说明人的本性。所以推测本句意为，“在接下来的章节，事情变得更加不寻常”，所以C选项正确。25.A细节理解题。文章将锡罐、游泳池、落菇和鼠狗与人类逐个比较。锡罐能盛东西，而人脑不能。人体与游泳池有着类似的内容，但人体内没有人在游泳。蹈菇是活的，更像人类，但没有嘴巴和大脑。鬣狗有嘴巴和大脑，最像人类，所以A选项正确。26.B推理判断题。文章将锡罐、游泳池、落菇和酸狗与人类进行比较，做比较是作者表达的主要方式，所以B选项正确。27.D推理判断题。根据文章第一段和最后一段，再结合下文内容可知，本文是对一本书进行简要介绍和评述，所以D选项正确。·【C篇】【本文主要介绍农业生态旅游，该旅游方式为城市生活的人们提供了独特的乡村体验，孩子们可以从其中体验到从农场到餐桌背后的世界，不仅培养了他们的劳动观念，更使他们认识到粮食的来之不易。】28.A目的意图题。通读第一段可知，该段主要描述了孩子和大人们在农场收集鸡蛋的情景：接着第二段首句The egg harvest is a brief,carefully designed agritourism experience.提出本文主题：农业生态旅游。据此可知，第一段描述大人孩子检鸡蛋是为了引出本文农业生态旅游的主题，故A项正确。29.B细节理解题。根据第二段第二句“Snatching a few eggs and uprooting a few vegetables onthe Farm tour don't constitute a full day's work,but it is also a useful reminder that fooddoesn't just magically appear on restaurant plates and grocery store shelves..”可知孩子们可以做一些简单而有意义的农活。所以选B。干扰项C,可从第二段最后一句“Visitors cantake those eggs home or bring them to the on-farm restaurant,Clay,where a chef will usethem to prepare breakfast”,可知，游客将鸡蛋带到农场餐饮，厨师会用这些鸡蛋准备食物，而不是游客们自已做饭。30.D细节推断题。根据倒数第二段第二句“.enterprising farmers have found plenty ofopportunities to sell their rural lifestyle along with their crops.”可知有远见的农民在出售农作物时也在宣传他们的生活方式。故D符合文意。

2024年河南省普通高中招生考试模拟试卷物理（导向一）参考答案1.欧姆电阻2.响度声源3.引力变短做功4.电磁感应现象机械5.大2000126.升华B面，金属升华成气体向外喷出，即产生一个向前的力，物体间力的作用是相互的，所以气体会给卫星一个向后的力，使卫星减速。7.B8.D9.B10.C11,D【解析】A.图中A点为火线，测电笔接触A点，氖管会发光，故A不正确，不符合题意；B.铜丝的电阻率小，熔点高，在电流过大时不易熔断，不能用铜丝代替保险丝，故B不正确，不符合题意；C.闭合开关时，保险丝未烧断，不可能是电灯短路，若灯泡短路电路的电流过大，保险丝会烧断，所以应该是灯泡断路，故C错误，不符合题意；D.若在三孔插座中接入空调后，空调不工作，测电笔测试三孔插座左右两孔氖管都亮，则可能是某处零线断路。故选D。12.A【解析】A.“刷脸”时的成像原理与照相机相同，C选项错误。因此，物体应距镜头2倍焦距以外，故A正确。B.摄像头成像利用的是光的折射，B选项错误。D.“刷脸”时，面部经摄像头应成倒立缩小的实像。D选项错误。13.BD【解析】A.潜水艇是通过改变自身重力实现沉浮的，而水母是通过改变浮力实现沉浮的，原理不同，故A错误；B.水母漂浮时，浮力等于其重力，水母沉在水底时，浮力小于其重力，所以水母漂浮时受到的浮力大于其沉在水底时受到的浮力，由阿基米德原理可知，水母漂浮时比沉在水底时排开水的重力大，故B正确；C.水母在下沉过程中，深度增大，根据液体压强公式可知，受到水的压强变大，故C错误；D.水母悬浮时，浮力等于其重力；若体积变大时，其排开水的体积变大，根据阿基米德原理可知，浮力变大，浮力大于重力，则水母会上浮，故D正确。故选BD。14.BD【解析】C.由串联电路的电流特点可知，将它们串联在3V的电源上时通过它们的电流相等，由图像可知，当通过它们的电流为0.4A时，甲两端的电压为2V,乙两端的电压为1V,由串联电路的电压特点可知，此时电源电压=U+U2=2V+1V=3V,符合题意，即此时电路中的电流为0.4A,故A、C不符合题意；B.由欧姆定律可知，电路的总电阻R=号0=1.5Q,故B符合题意；D.电路的总功率P=I=3V×0.4A=1.2W,故D符合题意。故选BD15.16.个F滑道上段bB支架底座物理试卷（导向一）参考答案第1页共2页
