15、的计算题量为两道，计算难度较大，多考查的是基本公式和基本规律的简单应用。计算繁杂。注重物理知识的应用，如第 21 题考查了全自动米糊机工作原理，结合工作过程中电热管和电动机交替工作 P-t 图象，通过公式 W=Pt计算电能，联系比热容的计算对加热效率相关内容的考查。三、学生答题情况分析 1基础知识和基本技能掌握的不好 试卷中的大部分题是考查基础知识和基本技能的，其中有些题得分率偏低甚至一部分同学综合应用题得 0 分或直接白卷，表明一些学生在基础知识方面尚有欠缺。2不能灵活应用物理知识分析和解决实际问题 试卷中很多题目从日常生活、科学技术和学生实验探究中设置情景，让学生发现问题，应用物理的基本概
16、念和基本规律解决问题，但学生将物理知识与生活实际脱离，知识与现象之间仍处于相对游离状态，不能很好的解决。3学生对学科交叉与综合方面的知识认识、掌握不够，科学素养不高，利用各学科综合知识解决物理问题的能力相对较差，通过阅卷发现学生的计算能力普遍较差，很多时候物理公式能写对，相关数据也能代对，就是最后的计算结果容易出现问题，因此在以后的教育教学中必须继续加强学生数学计算能力的培养。4学生的思维方法，语言文字表达，解题过程缺乏规范训练，严格要求。（如：计算题不写解、答，不写原始公式，不写文字叙述，乱套公式，乱用字母，不注意单位及换算等。）四、具体的试卷内容分析（识图与作图）本次试卷中识图与作图题共有

24、电流的变化，从而判断滑片的移动情况。解答：小磁针静止时 N极向左，则有磁极间的相互作用可知，通电螺线管右端为 S 极，则左端为 N 极，根据安培定则则可以判断电源的右端为正极，左端为负极；为使通电螺线管的磁性增强，需正大电路中电流，由欧姆定律可知要减小电路中的电阻，故滑片向右移动即向 b 端移动。点评：通电螺线管磁极的判定要利用安培定则，安培定则中涉及三个方向：电流方向与线圈绕向即四指的指向：磁场方向即大拇指的指向。在关于安培定则的考查中，往往是知二求一。2第 14“题开瓶起子”主要考查杠杆五要素（支点 O、动力 F1、动力臂 L1、阻力 F2、阻力臂 L2）的掌握，力臂的画法，在使用杠杆时分
25、清楚动力和阻力。解析：（1）知道力臂是从支点到力的作用线的距离，由支点向力的作用线引垂线，垂线段的长度即为力臂；（2）掌握动力和阻力的概念，在此题中盖子对起子的力即为阻力。解答：（1）首先在 F1 的方向上做出力 F1 的作用线，然后从支点 O 向 F1 的作用线引垂线，垂线段的长度即为力臂 L1。（2）F1 使起子逆时针转动，其中盖子对起子的力阻碍了起子的转动，所以是阻力 F2，方向竖直向下。点评:考查杠杆中力臂的画法，关键是正确的理解掌握力臂的概念，找到支点和力的作用线。3第 15 题“木球静止在水面上”考查的知识点力的示意图，二力平衡条件（等大、反向、同体、共线）的应用。解析：木球在水中
26、受到重力和浮力的作用，重力的方向竖直向下，浮力的方向竖直向上，由于木球漂浮，因此受到的力是平衡力，重力和浮力相等。解答:木球漂浮在水面上，重力和浮力是一对平衡力，二者大小相等，方向相反，作用在同一直线上。点评:作力的示意图，要用一条带箭头的线段表示力，线段的长度表示力的大小，箭头表示力的方向，起点或终点表示力的作用点。本题考查重力的方向，注意漂浮在水面上的物体其重力方向也是竖直向下的。4第 16 题“平面镜成像”考查的知识点平面镜成像的相关作图。解析：根据平面镜成像特点，像与物关于平面镜对称（等大、等距、连线垂直、虚像）可以先作出物体 A、B 端点 AB 的像点 A1、B1，连接 A1、B1
27、即为物体 AB 在平面镜中所成的像。解答：根据数学中作对称图形的基本方法，作出物体 AB 两个端点 A、B 的对称点 A1、B1，连接 A1、B1 即为物体 AB 在平面镜中所成的像。文档编码:CX5G2R5R10A1 HJ6D9T8S4I9 ZL10I1Z6C8Y6文档编码:CX5G2R5R10A1 HJ6D9T8S4I9 ZL10I1Z6C8Y6文档编码:CX5G2R5R10A1 HJ6D9T8S4I9 ZL10I1Z6C8Y6文档编码:CX5G2R5R10A1 HJ6D9T8S4I9 ZL10I1Z6C8Y6文档编码:CX5G2R5R10A1 HJ6D9T8S4I9 ZL10I1Z6C8

35、规律弄不清，相似的概念或规律不能辨析。2生活知识贫乏 现在的学生不注意观察和体验生活，生活常识缺乏，在联系生活生产实际、运用物理知识解决实际问题等方面的能力较弱。3实验技能薄弱 主要表现在物理知识与物理现象混淆不清，不关注实验过程，不明确实验过程中各操作步骤的目的和实验方法的应用，不注意观察实验现象，不会正确分析实验数据，答不出实验现象及实验结论。4灵活应用不够 许多学生还是习惯于背概念、代公式，对题意的理解、方法的选择不灵活，或不能用所学的物理知识解决生活中的实际问题。5综合计算题解答较差，说明教学中对培养学生综合分析、概括能力和应用物理知识解决问题的能力注意不够。六、教学及中考复习备考建议
36、 针对今年中考中出现的各种情况，在今后的教学中应积极做到以下几点：1不代替学生审题：在教学过程中，无论是讲例题还是做习题，都要引导学生自己读题，找出关键词，明确已知条件，逐步培养学生的审题能力 2加强规范训练：一方面，教学时教师要用规范语言教学，注意从物理基本原文档编码:CX5G2R5R10A1 HJ6D9T8S4I9 ZL10I1Z6C8Y6文档编码:CX5G2R5R10A1 HJ6D9T8S4I9 ZL10I1Z6C8Y6文档编码:CX5G2R5R10A1 HJ6D9T8S4I9 ZL10I1Z6C8Y6文档编码:CX5G2R5R10A1 HJ6D9T8S4I9 ZL10I1Z6C8Y6文

44、答题情况看，部分学生的基础知识掌握得不够牢固，对物理概念掌握似是而非，不能灵活应用物理知识分析问题。在今后教学中要强调重视基础知识、基本概念的教学，除了让学生知道概念、规律外，还要让他们知道概念的形成和规律的发现过程；对于重要的概念和规律，要让学生从不同角度、不同层次去理解和应用，以便提高学生的知识应用能力。5加强实验教学，培养科学探究能力：物理是一门以观察、实验为基础的科学。许多物理知识是通过观察和实验认真地总结和思索得来的。因此，加强实验教学，实施探究式课堂的教学模式，是提高学生综合实验能力的必经之路。教学中教师要根据教材的内容多做演示实验或随堂实验，有步骤、有计划地对科学探究的七个要素进
45、行全面的培养，但不论采用什么方式，都要让学生经历探究过程，理解实际探究过程中每一个要素的具体步骤和方法；培养学生的动手动脑、观察、分析归纳、抽象概括等分析问题、解决问题的能力。6密切联系实际，关注知识的应用：从生活走向物理，从物理走向社会，是物理新课程的重要理念之一。回顾几年来的中考物理试题可以看到，许多题目的情境都能在生活生产中找到类似的原型。因此，在教学中要找准教学内容与实用技术间的最佳结合点，强化物理与实际的结合，要紧密联系生活和生产中的实际问题引导学生思维，多分析应用实例，让学生的头脑中不再是枯燥的公式、概念和规律，而是具备能将复杂问题简单化，让学生通过参与应用物理知识解决实际问题的过
