2022_2023学年新教材高中语文模块综合质量检测部编版选择性必修下册

模块综合质量检测(时间150分钟 满分150分)一、现代文阅读(35分)(一)现代文阅读Ⅰ(本题共5小题,19分)阅读下面的文字,完成1~5题。

材料一:古代文学上,“文学自觉”指的是文学创作主体意识到文学的独立性和价值性,自觉地对文学的本质和发展规律等进行探讨和认识,促进文学按其自身的规律向前发展。

根据当代学者胡旭的研究,中国文学自觉有以下标志:标志之一是张衡《归田赋》的出现。

张衡曾用十年时间写成《二京赋》。

该赋的主旨是讽谏帝王公侯节俭,但这篇花费巨大精力所作的大赋,于政教却丝毫无补。

面对着朝政日非、江河日下的局面,其道家思想开始抬头。

《归田赋》中表现了隐居生活的恬淡情趣。

赋中分明已有一个抒情主人公在,自我意识加强了,个人价值得到了关注。

此后,抒情小赋不断出现,辞赋成了文人抒情写意的工具,实现了文学的自觉。

标志之二是“古诗十九首”的出现。

大约在桓、灵之世,出现了一批文人五言诗,其代表就是选录于《昭明文选》的“古诗十九首”。

古诗在内容上表现了“人的自觉”。

“十九首”的内容不外游子之歌和思妇之词两个方面,诗人们慨叹人生的短促和前途的渺茫,抒写了羁旅愁怀和离别相思,情调是悲哀而深沉的,这些慨叹正是对人生的执着与重视。

“古诗十九首”的抒情十分真实强烈,作者们对自己的种种情感,毫不掩饰,一寄之于诗。

这说明古诗的作者们不再把文学作政教的附庸,而是为满足自己的抒情需要进行创作;人的主题鲜明了,文学成了表现人生、人的命运、人的心灵的文学。

标志之三是散文创作方面新面貌的出现。

首先是各体散文的长足发展。

以文体而言,碑、铭、诔、箴、书、笺、檄、策、令、议、记、嘲、谒文、连珠等,种类繁多。

其次,东汉中后期散文逐渐趋向整齐华美。

一是在句式、音节、辞藻、用典等方面做文章,着力创造出一种形式美;二是讲究散文风神的飘逸与灵动。

(摘编自“百度百科”,有删改)材料二:鲁迅先生在《魏晋风度及文章与药及酒之关系》的演讲中指出“用近代的文学眼光来看,曹丕的一个时代可说是‘文学的自觉时代’”,其本意为嘲讽新月派与创造社“为艺术而艺术”的文学主张,孰料这一讽喻时事、有感而发的观点竟在传播中异化,“魏晋文学自觉说”在学界影响愈加广泛。

火灾自动报警系统模块调试检测检验批质量验收记录

火灾自动报警系统模块调试检测检验批质量验收记录

火灾自动报警系统模块调试检测检验批质量验收记录首先,进行模块调试。

模块调试是指对各个模块进行功能和效果的检验,以确保系统的正常运行。

调试工作一般分为硬件调试和软件调试两部分。

在硬件调试中,需要检查模块的电源供应是否正常,连线是否稳固,传感器是否正确接入等。

在软件调试中,需要检查模块的程序是否正确,是否能正常触发报警等。

模块调试的结果应记录在调试记录表中,包括调试的时间、人员、过程和结果等。

接着,进行检测。

检测是指对整个系统进行全面的检查和测试,以确保系统的性能和可靠性。

检测工作包括系统的基本功能测试、故障测试和稳定性测试等。

基本功能测试是检查系统的各个模块是否按照设计要求工作,例如报警器是否正常响铃,信息是否正确显示等。

故障测试是模拟各种故障情况,包括传感器故障、电源故障等,检验系统是否能够正确响应和处理。

稳定性测试是对系统进行长时间的运行测试,检验系统在长期使用中是否稳定可靠。

检测的结果也应记录在检测记录表中,包括时间、人员、过程和结果等。

最后,进行检验批质量验收记录。

检验批质量验收是对整个系统的质量进行评估,以确定系统是否符合相关标准和规范要求。

质量验收包括设备外观检查、安装位置划定、电气连接检查等。

设备外观检查是对设备的外观进行检查,包括外壳是否完好、显示器是否清晰等。

安装位置划定是对设备的安装位置进行检查,包括是否符合设计要求、是否方便维修等。

电气连接检查是对设备的电气连接进行检查,包括接线是否正确、接点是否稳定等。

检验批质量验收记录应包括验收的时间、人员、过程和结果等。

综上所述,火灾自动报警系统模块调试、检测和检验批质量验收记录是确保系统正常运行的重要工作。

通过这些工作,可以提高系统的性能和可靠性,保障人民的生命和财产安全。

(1)求f(x)的解析式,并讨论f(1)和f(-1)是函数f(x)的极大值还是极小值; (2)试求函数f(x)在x =-2处的切线方程. 解析: (1)f ′(x)=6ax 2+2bx -6, 因为f(x)在x =±1处取得极值,所以x =±1是方程3ax 2+bx -3=0的两个实根.所以⎩⎪⎨⎪⎧-b3a =0,-33a =-1,解得⎩⎪⎨⎪⎧a =1,b =0.所以f(x)=2x 3-6x ,f ′(x)=6x 2-6.令f ′(x)>0,得x >1或x <-1; 令f ′(x)<0,得-1<x <1.所以f(-1)是函数f(x)的极大值,f(1)是函数f(x)的极小值.(2)由(1)得f(-2)=-4,f ′(-2)=18,即f(x)在x =-2处的切线的斜率为18. 所以所求切线方程为y -(-4)=18[x -(-2)], 即18x -y +32=0. 21.(12分)设函数f(x)=x 3-92x 2+6x -a. (1)对于任意实数x ,f ′(x)≥m 恒成立,求m 的最大值; (2)若方程f(x)=0有且仅有一个实根,求a 的取值范围. 解析: (1)f ′(x)=3x 2-9x +6=3(x -1)(x -2).因为x ∈(-∞,+∞),f ′(x)≥m ,即3x 2-9x +(6-m)≥0恒成立,所以Δ=81-12(6-m)≤0,解得m ≤-34,即m 的最大值为-34.(2)因为当x <1时,f ′(x)>0;当1<x <2时,f ′(x)<0; 当x >2时,f ′(x)>0.所以当x =1时,f(x)取极大值f(1)=52-a ;当x =2时,f(x)取极小值f(2)=2-a ,故当f(2)>0或f(1)<0时,f(x)=0仅有一个实根. 解得a <2或a >52.22.(14分)某椭圆的中心是原点,它的短轴长为22,一个焦点为F(c,0)(c >0),x轴上有一点A ⎝ ⎛⎭⎪⎫a 2c ,0且满足|OF|=2|FA|,其中a 为长半轴长,过点A 的直线与该椭圆相交于P ,Q 两点.求:(1)该椭圆的方程及离心率;(2)若OP →·OQ →=0,求直线PQ 的方程.解析: (1)依题意可设椭圆的方程为x 2a 2+y 22=1(a >2),由已知得⎩⎪⎨⎪⎧a 2-c 2=2,c =2⎝ ⎛⎭⎪⎫a 2c -c ,解得⎩⎪⎨⎪⎧a =6,c =2.所以椭圆的方程为x 26+y 22=1,离心率e =63.(2)由(1)可得点A(3,0),由题意知直线PQ 的斜率存在,设为k , 则直线PQ 的方程为y =k(x -3),由方程组⎩⎪⎨⎪⎧x 26+y22=1,y =k (x -3),得(3k 2+1)x 2-18k 2x +27k 2-6=0,依题意知,Δ=12(2-3k 2)>0,得-63<k <63. 设P(x 1,y 1),Q(x 2,y 2),则x 1+x 2=18k 23k 2+1,x 1x 2=27k 2-63k 2+1,从而得y 1=k(x 1-3),y 2=k(x 2-3), 于是y 1y 2=k 2(x 1-3)(x 2-3).因为OP →·OQ →=0,所以x 1x 2+y 1y 2=0, 解得5k 2=1,从而k =±55∈⎝ ⎛⎭⎪⎪⎫-63,63,所以直线PQ 的方程为x -5y -3=0或x +5y -3=0.。

用万用表来检测电子元器件的好坏

用万用表来检测电子元器件的好坏

用万用表来检测电子元器件的好坏变频器故障处理--电子元器件的维修在变频器维修过程中,根据故障情况要用万用表来检测电子元器件的好坏,如测量方法不正确就很可能导致误判断,这将给维修工作造成困难,甚至造成不必要的经济损失。

测量方法分为元器件测试和线路板在路测试两种方式。

在路测试:断开变频器电源,在不拆动线路板元器件的条件下,测量线路板上的元器件。

对于元器件击穿、短路、开路性故障,这种检测方法可以方便快捷的查找出损坏的元器件,但还应考虑线路板上所测元器件与其并联的元器件对测量结果所产生的影响,以免造成误判断错误。

下面介绍元器件好坏的判断方法:一、普通二极管的检测用MF47型万用表测量,将红、黑表笔分别接在二极管的两端,读取读数,再将表笔对调测量。

根据两次测量结果判断,通常小功率锗二极管的正向电阻值为300-500Ω,硅二极管约为1kΩ或更大些。

锗管反相电阻为几十千欧,硅管反向电阻在500kΩ以上(大功率二极管的数值要小的多)。

好的二极管正向电阻较低,反向电阻较大,正反向电阻差值越大越好。

如果测得正、反向电阻很小均接近于零,说明二极管内部已短路;若正、反向电阻很大或趋于无穷大,则说明管子内部已断路。

在这两种情况下二极管就需报废。

在路测试:测试二极管PN结正反向电阻,比较容易判断出二极管是击穿短路还是断路。

二、三极管检测将数字万用表拨到二极管档,用表笔测PN结,如果正向导通,则显示的数字即为PN结的正向压降。

先确定集电极和发射极;用表笔测出两个PN结的正向压降,压降大的是发射极e,压降小的是集电极c。

在测试两个结时,红表笔接的是公共极,则被测三极管为NPN型,且红表笔所接为基极b;如果黑表笔接的是公共极,则被测三极管是PNP型,且此极为基极b。

三极管损坏后PN结有击穿短路和开路两种情况。

在路测试:在路测试三极管,实际上是通过测试PN结的正、反向电阻,来达到判断三极管是否损坏。

支路电阻大于PN结正向电阻,正常时所测得正、反向电阻应有明显区别,否则PN结损坏了。

装配式建筑施工中的模块精度检测与控制方法

装配式建筑施工中的模块精度检测与控制方法

装配式建筑施工中的模块精度检测与控制方法一、引言装配式建筑作为现代建筑领域的重要发展方向,在提高施工效率和减少环境污染方面具有显著优势。

而在装配式建筑施工过程中,模块精度的检测与控制是确保建筑质量和整体稳定性的关键。

二、模块精度检测方法1. 模块尺寸测量技术模块尺寸测量是模块精度检测中的一项基础工作。

常用的方法包括激光扫描仪、全站仪等。

激光扫描仪可以快速、准确地获取模块表面的三维数据,并通过比对设计图纸进行误差分析。

全站仪则通过自动定位和测量功能,实现对模块尺寸的高精度测量。

2. 模块平整度测试方法模块平整度是指模块表面的水平或垂直偏差程度。

常用的测试方法包括水平仪、电子水平仪和全站仪等。

通过将测试设备放置在不同位置,对模块表面进行连续采样并进行数据分析,可以得出模块表面平整度的指标。

3. 模块垂直度检测方法模块垂直度是指模块表面与竖直方向的夹角。

常用的检测方法包括全站仪和电子水平仪等。

通过对模块上不同位置进行连续测量,并计算出角度误差,可以评估模块的垂直度。

4. 模块间接缝尺寸控制方法模块间接缝尺寸的控制对于确保装配式建筑整体结构的稳定性和连续性至关重要。

常用的控制方法包括龙骨加固、调整螺栓等。

通过合理设置龙骨和调整螺栓的位置,可以达到对模块间接缝尺寸进行精确定位和调整的目的。

5. 模块连接力测试方法模块连接处力学性能的测试是确保装配式建筑结构强度和稳定性的重要环节。

常用的测试方法包括拉伸试验、剪切试验和扭转试验等。

通过在连接处施加相应力量并进行测试分析,可以评估连接条件是否符合设计要求。

三、模块精度控制方法1. 模块前期工程准备在开始装配式建筑施工之前,需要进行充分的前期工程准备。

包括制定详细的装配方案和施工计划、确定模块尺寸标准、选择合适的模块制造厂家等。

2. 模块制造过程质量控制模块制造过程中的质量控制是保证装配式建筑精度的重要环节。

需要确保原材料符合设计要求,制定严格的生产工艺规范,并进行全程监控和抽样检测。

高中物理(新人教版)选择性必修一课后习题:第四章模块检测题(一)(课后习题)【含答案及解析】

模块检测题(一)(时间:60分钟满分:100分)一、单项选择题(本题共7小题,每小题4分,共28分,每小题只有一个选项符合题目要求)1.(2021浙江绍兴诸暨中学高二期中)下列说法不符合两列波相遇时的情形的是()A.相遇之后,振幅小的一列波将减弱,振幅大的一列波将加强B.相遇之后,两列波的振动情况与相遇前完全相同C.在相遇区域,任一点的总位移等于两列波分别引起的位移的矢量和D.几个人在同一房间说话,相互间能分辨出来,是因为声波在相遇时互不干扰,每一列波引起的振动情况都保持不变,而质点的振动则是两列波共同作用的结果,选项A错误,选项B、C正确;几个人在同一房间说话,声音振动发出的声波在空间中相互叠加后,并不改变每列波的振幅、频率,所以声波传到人的耳朵后,仍能分辨出不同的人所说的话,故选项D正确。

本题选错误的选项,故选A。

2.(2020湖南边城高级中学高二开学考试)下列几种物理现象的解释中,正确的是()A.跳远时在沙坑里填沙,是为了减小冲量B.在推车时推不动是因为推力的冲量为零C.砸钉子时不用橡皮锤,只是因为橡皮锤太轻D.船舷常常悬挂旧轮胎,是为了延长作用时间,减小作用力,运动员动量变化量一定,受到的冲量一定,在沙坑里填沙,是为了延长力的作用时间,减小运动员受到的力,故A错误;在推车时推不动是因为推力小于最大静摩擦力,推力的冲量Ft不为零,故B错误;砸钉子时不用橡皮锤,是由于橡皮锤有弹性,作用时间长,根据动量定理Ft=Δp,产生的力小,故C错误;船舷常常悬挂旧轮胎,是因为轮胎能延长作用时间,减小作用力,故D正确。

3.如图所示为一显示薄膜干涉现象的实验装置,P是附有肥皂膜的铁丝圈,S是一点燃的酒精灯。

在图示的情况下()A.从肥皂薄膜的右面观察时,在薄膜上可看到水平条纹B.从肥皂薄膜的右面观察时,在薄膜上可看到竖直条纹C.从肥皂薄膜的左面观察时,在薄膜上可看到水平条纹D.从肥皂薄膜的左面观察时,在薄膜上可看到竖直条纹,所以应该从肥皂薄膜的右面观察;路程差(膜的厚度的两倍)是半波长的偶数倍时,振动加强,为亮条纹,路程差是半波长的奇数倍时,振动减弱,为暗条纹,肥皂薄膜越往下越厚,故条纹水平排列。

模块质量检测

模块质量检测

模块质量检测(时间:90分钟满分:100分)一、选择题(每小题2分,共36分)1.改革是人类历史发展的一曲不朽旋律。

下列关于改革的说法和认识正确的是()①改革就是要彻底革除旧的、传统的一切东西②改革所采用的是一种自上而下的、和平的方式③改革是统治者希望通过和平的、没有暴力的方式来完善社会制度并巩固自己的统治④改革中也充满了复杂性、多样性与艰巨性A.①②③B.②③④C.①②③④D.②③解析:改革属于和风细雨式的,“彻底革除”更多地属于革命的范畴,故①不正确。

答案:B2.平民的境况是极其艰苦的,借了财主的债若还不清,财主就在借债者的土地上竖起债务碑石。

借债者为财主做工,收成的六分之五给财主,自己只有六分之一。

如果收成不够缴纳利息,财主便有权在一年后把欠债的平民及其妻、子变卖为奴。

这种状况盛行于() A.公元前6世纪初之前的雅典B.梭伦改革后的雅典C.克里斯提尼统治时期的雅典D.伯里克利时期的雅典解析:材料反映的史实是债务奴隶制。

此制度在梭伦改革中被废除,故其盛行应该在梭伦改革前。

答案:A3.《管子·乘马》载:“是故夜寝早起,父子兄弟不忘其功,为而不倦,民不惮劳苦。

”对该材料的理解与表述,不正确的是()A.该现象与管仲改革赋税制度有关B.该现象的发生根源是铁器牛耕的使用C.该现象导致私田越来越多D.该现象推动封建制度在齐国确立解析:材料反映的是人民的积极劳作,这在井田制占主导的时期是很难出现的。

故该时期属于井田制逐渐瓦解的阶段,这一时期应该属于春秋后期,封建制度逐渐确立是在战国时期。

答案:D4.“画野分民乱井田,百王礼乐散寒烟”反映了春秋战国时期的时代特征是() A.生产力的发展B.争霸战争频繁C.思想文化繁荣D.社会动荡变革解析:诗句的含义是井田制逐渐瓦解,分封制逐渐崩溃,它反映了春秋战国时期社会的动荡与变革。

答案:D5.针对商鞅变法,大夫杜挚曰:“臣闻之,利不百,不变法;功不十,不易器。
