如东高级中学2018-2019学年高一上学期10月月考物理试卷一、选择题1.下列情况中的运动物体,能被看成质点的是()A. 在冰面上旋转的花样滑冰运动员B. 研究飞往火星的宇宙飞船最佳运行轨道C. 研究飞行中直升飞机上的螺旋桨的转动情况D. 研究子弹头射穿木板经历的时间【答案】B【解析】【详解】点没有大小,谈自转无意义;故研究在冰面上旋转的花样滑冰运动员动作时,运动员不可以简化为点,故A错误;研究飞往火星的宇宙飞船最佳运行轨道时,宇宙飞船的大小可忽略不计,可看做质点,选项B正确;研究飞行中直升飞机上的螺旋桨的转动情况时,不能忽略螺旋桨的大小,不能看做质点,选项C 错误;研究子弹头射穿木板的时间时,要考虑子弹的长度,不能简化为质点;故D 错误;故选B.【点睛】物体能否看成质点,不是看物体绝对质量或体积,而是看物体的大小和形状对所研究的问题影响能否忽略不计.2.关于伽利略对自由落体的研究,下列说法正确的是()A. 伽利略认为,在同一地点重的物体和轻的物体下落的快慢不同B. 伽利略猜想运动的速度与下落时间成正比,并直接用实验进行了验证C. 伽利略通过数学推演并用小球在斜面上的运动验证了位移与时间的平方成正比D. 伽利略用小球在斜面上的运动验证了速度与位移成正比【答案】C【解析】【详解】亚里士多德认为在同一地点重的物体和轻的物体下落快慢不同,故A错误;伽利略猜想自由落体的运动速度与下落时间成正比,并未直接进行验证,只是验证了位移与时间的平方成正比,然后在斜面实验的基础上的理想化推理,故BD错误,C正确。

故选C。

【点睛】伽利略的“理想斜面实验”是建立在可靠的事实基础之上的,它来源于实践,而又高于实践,它是实践和思维的结晶.3.在交警处理某次交通事故时,通过监控仪器扫描,输入计算机后得到该汽车在水平路面上刹车过程中的位移随时间变化的规律为(的单位是,单位是).则该汽车在路面上留下的刹车痕迹长度为()A.B.C.D.【答案】B【解析】【详解】根据位移时间公式和比较系数可得:v0=20m/s,a=-4m/s2,则根据匀变速直线运动的速度位移公式v2-v2=2ax,代入数据可得:x=50m,故B正确,ACD错误。

①真正的教养不追求任何具体的目的,一如所有为了自我完善而作出的努力,本身便有意义。

对“教养”(即精神和心灵完善)的追求,并非朝向某些狭隘目标的艰难跋涉,而是自我意识的增强和扩展,它使我们的生活更加丰富多彩,享受更多更大的幸福。

因此,真正的教养一如真正的体育,既是完成又是激励,随处都可到达终点却从不停歇,永远都在半道上,都在与宇宙共振,生存于永恒之中。

它的目的不在于提高这种或那种能力和本领,而在于帮助我们找到生活的意义,正确认识过去,以大无畏的精神迎接未来。

②为获得真正的教养可以走不同的道路。

最重要的途径之一,就是研读世界文学,就是逐渐熟悉和掌握各国作家与思想家的作品,以及他们在作品中留给我们的思想、经验、象征、幻象和理想的巨大财富。

这条路永无止境,任何人也不可能在什么时候将它走到头;任何人也不可能在什么时候将哪怕仅仅是一个文化发达的民族的全部文学通通读完并有所了解,更不用说整个人类的文学了。

然而对思想家或作家的每一部杰作的深入理解,都会使你感到满足和幸福——不是因为获得了僵死的知识,而是因为有了鲜活的意识和理解。

对于我们来说,问题不在于尽可能地多读和多知道,而在于自由地选择我们个人闲暇时能完全沉浸其中的杰作,领略人类所思、所求的广阔和丰盈,从而在自己与整个人类之间,建立起息息相通的生动联系,使自己的心脏随着人类心脏的跳动而跳动。

这,归根到底是一切生活的意义,如果活着不仅仅为着满足那些赤裸裸的需要的话。

读书绝不是要使我们“散心消遣”,倒是要使我们集中心智;不是要用虚假的慰藉来麻痹我们,使我们对无意义的人生视而不见,而是正好相反,要帮助我们将自己的人生变得越来越充实、高尚,越来越有意义。

③世界文学的辉煌殿堂对每一位有志者都敞开着,谁也不必对它收藏之丰富望洋兴叹,因为问题不在于数量。

江苏省南通市如东县2017~2018学年第一学期期末试卷高三数学一、填空题(本大题共14小题,每小题5分,共计70分.不需要写出解答过程,请将答案填写在答题卡相应的位置上..........)1.设全集U={0,1,2,3},集合A={1,2},B={1,3},则=_______.【答案】【解析】【分析】根据补集的概念得到{0,3},再由交集的概念得到结果.【详解】全集U={0,1,2,3},集合A={1,2},{0,3},则.故答案为:.【点睛】与集合元素有关问题的思路:(1)确定集合的元素是什么,即确定这个集合是数集还是点集.(2)看这些元素满足什么限制条件.(3)根据限制条件列式求参数的值或确定集合元素的个数,但要注意检验集合是否满足元素的互异性.2.已知点A(﹣1,2),B(1,3),则向量的坐标为_______.【答案】【解析】【分析】根据向量的坐标运算得到结果即可.【详解】已知点A(﹣1,2),B(1,3),则向量=(2,1).故答案为:.【点睛】本题考查了向量的坐标运算,较为简单.3.函数的定义域是_______.【答案】【解析】【分析】根据函数f(x)的解析式,列出使解析式有意义的不等式组,求出解集即可.【详解】函数f(x)=,∴∴f(x)的定义域为{x|0<x≤2且x≠1}.故答案为:{x|0<x≤2且x≠1}.【点睛】本题考查了根据函数的解析式求定义域的应用问题,是基础题目.求函数定义域的注意点:(1)不要对解析式进行化简变形,以免定义域变化。

(2)当一个函数由有限个基本初等函数的和、差、积、商的形式构成时,定义域一般是各个基本初等函数定义域的交集。

(3)定义域是一个集合,要用集合或区间表示,若用区间表示,不能用“或”连接,而应该用并集符号“∪”连接。

4.函数的最小正周期为_______.【答案】【解析】【分析】利用两角差的正切公式化简函数的解析式,再利用正切函数的周期性,得出结论.【详解】函数f(x)==tan(﹣x)=﹣tan(x﹣)的最小正周期为π,故答案为:π.【点睛】本题主要考查两角差的正切公式,正切函数的周期性,属于基础题.5.已知幂函数,其中{﹣1,0,,1,2,3},则使为偶函数,且在区间(0,)上是单调增函数的的值为_______.【答案】【解析】【分析】根据幂函数(x)=xα,f(x)为偶函数,则a为偶函数,在区间(0,+∞)上是单调增,则a>0,可得答案.【详解】由题意α∈{﹣1,0,,1,2,3},幂函数(x)=xα,f(x)为偶函数,则a为偶函数,在区间(0,+∞)上是单调增,则a>0,综上可得a=2.故答案为:2.【点睛】本题考查了幂函数的单调性和奇偶性的应用.属于基础题.在上,幂函数中指数越大,函数图象越靠近x轴(简记为“指大图低”),在(1,+∞)上,幂函数中指数越大,函数图象越远离x轴.幂函数的图象一定会出现在第一象限内,一定不会出现在第四象限内,至于是否出现在第二、三象限内,要看函数的奇偶性;幂函数的图象最多只能同时出现在两个象限内;如果幂函数的图象与坐标轴相交,则交点一定是原点.6.已知函数,其中e为自然对数的底数,则=_______.【答案】【解析】【分析】根据题意,由函数的解析式先求出f()的值,结合函数的解析式计算可得答案.【详解】根据题意,函数,则f()=ln()=﹣1,则f(f())=f(﹣1)=e﹣1=,故答案为:.【点睛】本题考查分段函数的求值,注意分段函数分段讨论,属于基础题.求分段函数的函数值,要先确定要求值的自变量属于哪一段区间,然后代入该段的解析式求值,当出现的形式时,应从内到外依次求值;求某条件下自变量的值,先假设所求的值在分段函数定义区间的各段上,然后求出相应自变量的值,切记代入检验,看所求的自变量的值是否满足相应段自变量的取值范围.7.已知函数,将函数图像向右平移个单位后与函数图像重合,则函数在区间[0,]上的单调减区间为_______.【答案】【解析】【分析】利用倍角公式降幂,再由辅助角公式化积,再由平移变换得到g(x),由复合函数的单调性求函数y=g(x)在区间[0,π]上的单调减区间.【详解】f(x)=2cos2x+sin2x﹣1=sin2x+cos2x=,将函数y=f(x)图象向右平移个单位后,得y=则g(x)=.由可得取k=0,可得函数y=g(x)在区间[0,π]上的单调减区间为.故答案为:【点睛】本题考查三角函数的恒等变换应用,考查y=Asin(ωx+φ)型函数的图象和性质,是基础题.考查了三角函数的平移问题,首先保证三角函数同名,不是同名通过诱导公式化为同名,在平移中符合左加右减的原则,在写解析式时保证要将x的系数提出来,针对x本身进行加减和伸缩.8.已知函数是定义在[﹣2,2]上的奇函数,且在区间[0,2]上是单调减函数,若,则x的取值范围是_______.【答案】【解析】【分析】由函数f(x)是奇函数,可得f(2x+1)<f(﹣1).根据单调性脱去“f”,求解即可.【详解】函数f(x)是定义在[﹣2,2]上的奇函数,且在区间[0,2]上是单调减函数.∴[﹣2,0]上单调减函数;由f(2x+1)+f(1)<0,即f(2x+1)<﹣f(1).∴f(2x+1)<f(﹣1).则解得:.则x的取值范围是故答案为:.【点睛】本题考查函数的单调性与奇偶性的综合应用,注意奇函数的在对称区间上的单调性的性质;对于解抽象函数的不等式问题或者有解析式,但是直接解不等式非常麻烦的问题,可以考虑研究函数的单调性和奇偶性等,以及函数零点等,直接根据这些性质得到不等式的解集。
