九年级英语上学期期末考试试卷分析 一、试题评价 本次试卷是120分的。试卷总体来说，难度适中。本次命题在考察学生英语基础知识的前提下，注重了对学生语言综合能力和知识迁移的考察,注重语言环境及文化背景的设置，减少了词汇、语法等单纯知识性的试题，增加了试题的灵活性、开放性、探究性及综合性。试题以听、读、写的形式，全面地检查了学生应掌握的英语基础知识和基本能力。 总体来说本套试题能够较全面地考核本册书的知识点，既考学生的基础知识，又考学生的能力，尤其是灵活的应变能力。从下面的数据分析看，本次考试成绩不是很理想。 二、数据统计分析： 三、学生对各题得分情况分析： 1.听力部分：此题考察学生是否能正确理解所听的内容，并具备用英语进行释义的能力，用英语回答问题的能力，在特定的语境中进行交际的能力。听力部分共六小节，设计由浅入深,由易到难,循序渐进,从知识到能力,具有一定的梯度,对于基础较好的学生来说，此套听力题略显简单，大部分都在20-28分之间。对有一定英语基础，但掌握不扎实的学生来说，听力还存在薄弱的环节。另外学生除了对听力的训练不够，答题的方法和技巧也掌握的不是很好。对于英语学习吃力的学生来说，听力是相当难的，成绩也很不理想。 2.笔试部分的基础知识题占三分之一以上，能力题占三分之二左右。此题注重考察词的辨析、语法以及习语等语言知识，在特定的语境中运用语言知识进行交际能力。此题知识覆盖面较广，重点、难点比较突出。 3.笔试中的补全对话共两段，这是由对话组成的两篇短文，对话语境不完整，试题要求学生在通读对话和掌握大意的基础上，用完整的语言补全对话，使其意思完整。题中的第一个对话，语境相对完整一些，学生答的相对较好。但第二个对话，语境虽然清晰,但学生不注意时态,语态的变化,失分较多。 4.笔试中的阅读理解，此题考察学生是否具备根据上下文猜测词意进行推理等思维活动，识别选择归纳所提供的信息，探索语篇中的表层含义和深层含义的阅读能力，从而达到获得正确的语言信息的目的。 5.笔试中的书面表达：第一篇内容比较简单，学生完成的较好。第二篇作文所涉及内容和学生的日常生活有着极大的关系,学生写的时候不觉的费力。但个别同学在语言的灵活应用上欠功夫，不能够把书上的语言恰当的运用到自己的作文中去,且中式英语较重, 语言表达不地道,语法错误较多。这说明学生在日常写作教学中我们还存在着问题，没能在很好的驾御教材的同时注重学生能力的培养。 四、今后教学方法方式及其建议

江西省南昌市2021届新高考物理一模试卷 一、单项选择题：本题共6小题，每小题5分，共30分．在每小题给出的四个选项中，只有一项是符合题目要求的 1．如图所示，质量为2kg 的物体A 静止于动摩擦因数为0.25的足够长的水平桌而上，左边通过劲度系数为100N/m 的轻质弹簧与固定的竖直板P 拴接，右边物体A 由细线绕过光滑的定滑轮与质量为2.5kg 物体B 相连。开始时用手托住B ，让细线恰好伸直，弹簧处于原长，然后放开手静止释放B ，直至B 获得最大速度已知弹簧的惮性势能为2 12 P E kx =（其中x 为弹簧的形变量）、重力加速度g=10m/s 2.下列说法正确的是（ ） A ．A 、 B 和弹簧构成的系统机械能守恒 B ．物体B 机械能的减少量等于它所受的重力与拉力的合力做的功 C ．当物体B 获得最大速度时，弹簧伸长了25cm D ．当物体B 获得最大速度时，物体B 速度为22 3 m/s 【答案】D 【解析】 【分析】 【详解】 A.由于在物体B 下落的过程中摩擦力做负功，所以系统的机械能不守恒，故A 错误； B.对物体B 分析，受到重力和拉力作用，W 拉力=△E 机，物体B 机械能的减少量等于所受拉力做的功，故B 错误； C.A 与B 为连接体，物体B 速度达到最大时，物体A 速度也最大，此时A 和B 的加速度为零，所受合力也为零，对物体B 受力分析，绳子的拉力 T B F m g = 对物体A 受力分析 A T F m g F μ+= 弹簧弹力 F kx = 则弹簧伸长了
0.2m 20cm x == 故C 错误； D.以A 和B 整体为研究对象，从静止到A 和B 速度达到最大的过程中，由功能关系可得 22A B B A 11()22 m m v m gx m gx kx μ+=-- 代入数据可得 m/s 3 v = 故D 正确。 故选D 。 2．下列说法正确的是（ ） A ．中子与质子结合成氘核时吸收能量 B ．卢瑟福的α粒子散射实验证明了原子核是由质子和中子组成的 C ．入射光照射到某金属表面发生光电效应，若仅减弱该光的强度，则不可能发生光电效应 D ．根据玻尔理论，氢原子的电子由外层轨道跃迁到内层轨道，原子的能量减少，电子的动能增加 【答案】D 【解析】 【分析】 【详解】 A ．中子与质子结合成氘核的过程中有质量亏损，释放能量，故A 错误； B ．卢瑟福的α粒子散射实验揭示了原子的核式结构模型，故B 错误； C ．根据光电效应方程知 0km E h W ν=- 入射光的频率不变，若仅减弱该光的强度，则仍一定能发生光电效应，故C 错误； D ．电子由外层轨道跃迁到内层轨道时，放出光子，总能量减小；根据 2 2kQq v m r r = 可知半径越小，动能越大，故D 正确。 故选D 。 3．如图所示，劲度系数为k 的轻弹簧的一端固定在墙上，另一端与置于水平面上质量为m 的物体P 接触，但未与物体P 连接，弹簧水平且无形变。现对物体P 施加一个水平向右的瞬间冲量，大小为I 0，测得物体P 向右运动的最大距离为x 0，之后物体P 被弹簧弹回最终停在距离初始位置左侧2x 0处。已知弹簧始终在弹簧弹性限度内，物体P 与水平面间的动摩擦因数为μ，重力加速度为g ，下列说法中正确的是 （ ）

初中英语期中考试试卷分析 目前我市使用了两个版本的初中英语教材：仁爱英语和新目标英语。仁爱英语命题的目的是了解学情；新目标英语命题的目的是进行教学质量调查。两者命题有一个共同点：实现新课程要求的三维目标，传道（情感、态度、价值观）、授业（引导学生掌握知识和技能）、解惑（引起主动学习，学会学习方法）。 一、试卷特点： 1.试卷注重基础，体现灵活运用，难度和区分度恰当无偏题、怪题出现。 试题注重考查学生在一定语境下对语言基础知识的掌握情况和综合运用英语的能力。语言基础知识的考查重点突出、覆盖面广；情景设置合理，避免了纯知识性的死记硬背题；词汇和语法的测试充分注意了语言的真实性、趣味性和实践性；注重语感，灵活性强，突出语言形式向语言意义的转化。 2．试题从知识立意逐渐向能力立意转变。 加大了能力考查的比重。试题突出了语言的交际性，强调在特定的语境中英语知识的灵活运用。适当增加了测试词汇量，加强能力检测。如阅读理解考查的内容注重了对学生在语境中运用语言能力的考查。加大了对语言的熟练程度和深层次能力考查的力度。如“阅读理解”部分注重了对归纳，推断和猜测整个句子等深层次能力的考查。阅读材料贴近生活，同时题材广泛，体裁多样、生动有趣，并富有思想性。淡化语法，强调能力。语法知识的测试充分注意了语言的真实性和实践性。纯知识性的试题的比例减少到最低限度，命题者通过设置不同的语境，把对语言知识的考查中心放到了根据上下文中和一定的语境中，让语法测试试题具有更积极和更现实的意义，能更多地体现语言的交际功能。 3．书面表达难度控制合理。 书面表达给学生留有充分发挥能力的空间，加大了考查学生综合运用语言能力的力度，使试卷更具现实性。书面表达题对初中英语教学有着良好的导向作用，要求学生要充分运用所学语言记录自己的真实情感，进一步体现了英语学科的交际性和工具性。 二、七年级英语试卷分析及教学建议 本次期中考试，七年级英语试卷题量适度、难易适宜，试题大部分都是基础题。从总体上说，试题出题范围很合适，适合七年级学情。对学生来说，只要细心，就会得高分。 第一题听力部分 本题满分为20分，得分率为60%，是本次考试失分最多的一道题，如听力IV,听对话，选答案，共5道小题，大部分学生只能做对一、两道题，究其原因，是学生听力训练少、考试经验不足所致。 第二题单项选择 本题共15分，得分率为86%。本题为基本题型，学生失分较少，不过，学生因语法知识欠缺，导致的问题还是显而易见的。如3. I am from Canada. ____ from the U.S.A. 学生知道应该填I am not,但试卷没有该选项，而是巧妙地提供了I’m not这个选项，学生不知道am和not没有缩写形式，大多选了B这个错误选项。5题中different后应跟名词复数这一点大部分学生也不知道。类似的语法点教师以后应该强调到。 第三题句型转换 本题共5分，学生平均只得了3分。问题多出在助动词do和does没有掌握好。 第四题补全对话 本题共10分，得分率在95%左右。这道题老师指导的不错，学生答的也不错。

2017-2018学年度第一学期期末测试九年级试卷分析洪山镇洪山九年制学校李品艳 一、试卷的基本情况分析 本次考试卷主要考查的是人教版九年级上教学内容，注重考查英语基础知识和基本技能，又强调学生在实际中运用英语的能力，所涉及的知识点的面比较广，题目设计比较灵活。试卷只有有笔试部分，没有停留，共八大题型（单项选择、完形填空、阅读理解、完成句子、短文填空、任务型阅读、补全对话、作文），总分120分，考试时间为120分钟。 本次试卷难度不大，学生各题型大体情况综述如下。 1，单选题注重考查课本所学单词及语法知识，难度不大。 2，完形填空。二篇完形填空难度适宜，和平时所练题型难度相当。 3，阅读，整体难度不大，注重细节考察，主要是考察信息提取能力。 4，完成句子，所考内容都是讲过的，但是学生错误不断。 5，补全对话，特别是第二个补全对话得分率极低，基础不牢。 6，最后是作文，本次作文是描写自己为考试准备，目的在于考察学生对第一单元所学内容的运用，题干中给出了提示句子，相对降低难度，而且此类型是写过讲过练过的，大部分同学都能动笔写，都能得到相应分数，优秀生本次作文写得较好。 7，本次试卷命题有以下几个导向： 8，1.九年级英语课堂教学中应重视基础知识的积累和听、说、读、写技能的训练，紧抓课本知识的学习巩固与训练。 9，2.要注重培养学生学习习惯--课前预习、准备习惯，课中听课、做笔记、合作探究的习惯； 10，3.课堂教学中要面向全体学生，紧抓优等生，不放弃后进生，师徒结对、小组合作互助，整体提高，减少两极分化。 11，二、存在问题及原因分析 12，（一）老师方面 1、重在抓新课学习，没有复习。 2、作业布置到位，督促检查不够到位，还需多加强对学生学习方法的指导. 3，学生的分组合作和师徒结有一定的学习效果，教师还需进一步加强对组长和师傅的指导，积极发挥师傅的带头引导作用。 （二）学生方面 1、学习基础差，学习成绩两极分化严重，学习自信心不足，容易自暴自弃。 2，大部分同学学习缺乏主动性，几乎很少有学生能主动学习英语，英语学习兴趣不足。 3，大部分学生懒惰，不能自主完成学习任务，作业拖拉，爱抄袭作业。 4，大部分学生没有良好的学习习惯，不能很好完成预习、复习任务，课堂中学习注意力不集中，需不断提醒才做笔记，有些人提醒也不动，他们独立完成作业情况更不容乐观。 5、学生晚上睡眠不足，白天爱打瞌睡，学习效率低下。 三、今后英语教学改进措施 １、英语教学应该抓好课本基本知识学习和巩固，加强答题技能训练。
