? “Materials science" involves investigating the relationships that exist between the structures and properties of materials. In contrast, “Materials engineering” is, on the basis of these structure-property correlations, designing or engineering the structure of a material to produce a predetermined set of properties.

“材料科学”涉及到材料的结构和性能之间的关系研究。相比之下,“材料工程”是在这些结构性能的相关的基础上,设计材料的结构以生产预定的一组属性。? “ Virtually” all important properties of solid materials may be grouped into s ix different categories: mechanical, electrical, thermal, magnetic, optical. and deteriorative.

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

一 我认为总结一下英语学习的经验是值得一试的。这里,我想谈谈三个相关的问题。 首先,大量阅读应被视作学习过程中的重点,因为我们是通过阅读获取最大量语言输入(language input)的。其次,尽可能多背一些好文章也十分重要。一方面,死记硬背(rote learning)确实无甚裨益,但另一方面,在真正理解基础上的熟记肯定对我们有好处。大脑中存储了大量很好的文章,我们在用英语表达自己思想的时候,就会觉得容易多了。最后,我们应该把所学到的东西用到实践中去,这是至关重要的。通过多读、多写、多听、多说,我们就能完成提高英语水平的任务。 I consider it worthwhile trying to summarize our experience in learning English. Here I would like to make three relevant points. First, wide reading should be taken as a priority in the learning progress, because it is through reading that we get the most language input. Next, learning by heart as many well-written essays as possible is also very important. On the one hand, rote learning/learning by rote is indeed of little help, but on the other hand, memorization/learning by heart with a good understanding will certainly be of benefit /do good to us. With an enormous store of excellent essays in our heads, we will find it much easier to express us in English. Finally, it's critical that we should put what we have learned into practice. By doing more reading, writing, listening and speaking, we will be able to the task of perfecting our English. 自从他加盟以来,乔治从早忙到晚。他总是乐呵呵的,一直全身心地扑在工作上。由于表现出色,他被提升为执行总裁(CEO=CHIEF EXECUTIVE OFFICER).从那以后,他尽力和工人打成一片,从不盛气凌人。另外,他制定了一些奖励制度,鼓励工人们努力工作。他相信忠诚和勤劳会大大促使公司获得成功。人们都说他是位出色的执行总裁。 George was on the run since the moment he came aboard. He was always cheerful and devoted himself heart and soul to his work. Because of his excellent performance he was promoted to CEO. From then on he tried hard to blend in with other workers and never threw his weight around. He also laid down/introduced a reward system to encourage the workers to work hard. He believed that loyalty and hard work would greatly contribute to the success of the company. By all accounts he was an outstanding chief executive officer. 也许你羡慕我,因为我可以借助计算机在家里工作。我也这么想,互联网使我的工作方便多了。我可以通过电子邮件撰写、编辑并交出我的文章,在网上与我的同事聊天,与老板讨论工作。我用鼠标一击,马上就能拿到我要的一切资料,获得最新的消息。可是,另一方面,用网络通信有时也令人沮丧。系统有可能瘫痪,更糟的是,因为没有面对面交谈的情感提示,键出的词有时候似乎很难理解。 Perhaps you envy me for being able to work from home on the computer . I agree that the Internet has made my job a lot easier. I can write, write and edit articles via email, chat with my colleagues on line and discuss work with my boss. With a click of
