数学专业英语一次函数专题
“数学专业英语一次函数专题”教学设计 1. 教学内容及解析 教学内容：与直角坐标系及一次函数相关的英语文献资料 内容解析：本节内容应从两个方面去考虑. 一方面，从数学知识的角度，本节所涉及的是从平面直角坐标系到一次函数的数学知识，都是学生学过的基础知识及其应用，是对于这些知识的拉练式复习，并作为后面用英语叙述解答相关问题知识基础；另一方面，从语言的角度，学生会接触到大量没有接触过，但他们却很熟悉的英语词汇及短语，主动学习的学生可以在老师的指导下快速理解其含义并加入到自己的知识体系中，但需要花时间巩固，是需要读、写、说来巩固的内容. 这也正是本节的重点和难点所在. 2. 教学目标及解析 教学目标：①能根据已有的数学知识和给出的单词对照表，将给出的相关数学定理及结论的英语版本翻译为中文；②能理解并解答用英语表述的相关数学问题；③能将解决数学问题的过程用英语进行书面表述；④初步了解用英语表达与直角坐标系及一次函数相关数学理论的范式. 目标解析：学生掌握基本词汇，并能阅读与本节内容相关的英语文献，是学习和使用数学专业英语的最基本要求，学生需要在学习的过程中逐渐由接受，即阅读或聆听，逐渐向输出，即书面和口头表达的方向发展. 为达到此目标，学生需要在课前独立完成对于本节需要的单词的学习，并阅读一系列简短的相关数学文献，并在这个过程中初步体会数学专业英语的表达范式；在课堂上，在教师的指导下对自己的认知进一步补充，并进行一定量的练习，暴露自己的问题，在教师的帮助下修正问题，完善认知. 3. 教学问题诊断分析 学生在进行语言表达时，往往受到母语的限制，对于非母语的表达方式的接受能力一时难以习惯，而数学对于表达能力则有更高的要求，要求叙述简洁、逻辑清晰，因此本教学设计强调学生在有相当阅读量的积累后，通过自主练习，逐渐感受用英语表达数学理论的基本范式. 教师在教学过程中的主要任务在于为学生提供合适的学习资料，在学生学习的过程中给予提示与指导，及时指出学生的问题并予以纠正. 对于语言的学习，阅读量的积累是至关重要的，教师在课堂上的讲解、学生在课堂上的练习，都只是学习的一部分环节，如果需要帮助学生正确掌握表达数学理论的范式，尽量不留死角，就必须保证课前预习和课后复习的有效性，预习复习材料的充足性，这对教师的教学资料的积累和学生自主学习能力，都是一个挑战. 4. 教学支持条件分析 学情条件：初二8班是实验班，学生有较强的学习热情和好奇心，也知道课前预习、课上参与学习活动、课后复习的重要性，在曾经的数学课程教学中，也有一定的课前预习，课堂讨论的传统，对于本教学设计的各个环节，是可以理解教师的用意，并遵循教师的指导进行学习活动. 在知识层面上，学生已经系统学习过一次函数相关的知识，课程中提供的学习资料都是学生熟悉的数学知识；学生在英语学习上，已经有多年的积累，对于英语语法的学

专业英语课后习题答案
Lesson2 Exercises 1. Put the following into Chinese. （1）Ohm’s law states that the voltage across a resistor is directly proportional to the current flowing through the resistor. The constant of proportionality is the resistance value of the resistor in ohms. 流过电路里电阻的电流，与加在电阻两端的电压成正比，与电阻的阻值成反比。这就是欧姆定律。 （2）Many materials, however, closely approximate an ideal linear resistor over a desired operating region. 不过，许多材料在规定的工作范围内非常接近理想线性电阻。 （3）It should be noted that an ideal voltage source (dependent or independent ) will produce any current required to ensure that the terminal voltage is as stated, whereas an ideal current source will produce the necessary voltage to ensure the stated current flow. 应该注意：一个理想电压源（独立或受控）可向电路提供任意电流以保证其端电压为规定值，而电流源可向电路提供任意电压以保证其规定电流。 （4）A different class of relationship occurs because of the restriction that some specific type of network element places on the variables. Still another class of relationship is one between several variable of the same type which occurs as the result of the network configuration, i. e., the manner in which the various element of the network are interconnected. 一种不同类型的关系是由于网络元件的某种特定类型的连接对变量的约束。另一类关系由于网络结构，即网络的不同元件互相连接的方式所产生的相同形式的一些变量间的关系。 （5）The thermal conductivity of metals is as much as several hundred times that of glass. 金属的导热率比玻璃高几百倍。 （6）Magnetic line of force will，whenever passible, travel through iron or other magnetic materials. 磁力线只要有可能就会通过铁或其它磁性材料。 （7）Actually, 0 o C is indeed the lower limit to temperatures capable of being attained. 事实上绝对零度确是所能达到的温度的最低限度。 2. Translate the following into English. （1）电路元件吸收或释放的功率为元件两端的电压与流过该元件电流的乘积。 The power absorbed or supplied by a circuit element is the product of the voltage across the element and the current through it. （2）理想独立电源是一个有源元件，它所提供的电压或电流不依赖于电路中其他变量。 An ideal independent source is an active element that provides a specified voltage or current that is completely independent of other circuit variables. （3）受控电源是一个有源元件，它所提供的电压或电流受电路中某部分电压或电流控制。 An ideal dependent (or controlled) source is an active element in which the source quantity is controlled by another voltage or current. （4）叠加定理为：线性电路中，任一电压或电流都是电路中各个独立电源单独作用时，在该处产生的电压或电流的叠加。 The superposition principle states that the voltage across (or current through) an element in a linear circuit is the algebraic sum of the voltages across (or current through) that element due to each independent source acting alone. （5）计算机可分为模拟计算机和数字计算机两种。Computers may be classfied as analog and digital．（6）新型晶体管的开关时间缩短了三分之二。The switching time of the new-type transistor is shortened three times． （7）超导体在电气应用上的重要性不能被估计过高。The importance of superconductor in the uses of electricity cannot be overestimated.
