一．中古英语时期 ?Beowulf is the oldest poem in the English language, and the most important specimen (范例、典范)of Anglo-Saxon literature, and also the oldest surviving epic in the English language. ?The romance is a popular literary form in the medieval period（中世纪）. It uses verse or prose to sing knightly adventures or other heroic deeds. ?Geoffrey Chaucer, one of the greatest English poets, whose masterpiece, The Canterbury Tales（《坎特伯雷故事集》）,was one of the most important influences on the development of English literature. ?Chaucer is considered as the father of English poetry and the founder of English realism. 二．文艺复兴Renaissance ?Renaissance refers to the period between the 14th and mid-17th centuries. It marks a transition(过渡) from the medieval to the modern world. ?It started in Italy with the flowering of painting, sculpture（雕塑）and literature, and then spread to the rest of Europe. ?Humanism is the essence of Renaissance -----Man is the measure of all things. ?This was England’s Golden Age in literature. Queen Elizabeth reigned over the country in this period. The real mainstream of the English Renaissance is the Elizabethan drama. The most famous dramatists in the Renaissance England ? ?“Of Studies” is the most popular of Bacon’s 58 essays. ?Thomas More ——Utopia ?Edmund Spenser——The Faerie Queene 相关练习 ? 1.

Shakespeare understood people more than any other writers. He could create characters that have
第二单元环境工程 这本书主要关于什么？ 这本书的目标是使工程和科学的学生了解学科间的研究环境问题：它们的起因，为什么它们被关注，我们怎么控制它们。这本书包括： ●描述环境和环境系统意味着什么 ●关于环境破坏基础原因的信息 ●理解环境问题本质和能够定量计算它们所必要的基本科学知识 ●目前运用在水,空气,污染问题的环境控制技术的状况 ●我们目前在很多关于理解和控制人类活动、自然之间复杂相互作用的科学知识上存在着相当大的空白 ●很多环境问题能运用目前的技术消除或减少，但因为社会缺少意愿这么做或在很多例子中因为缺乏资源去这样做，这些环境问题没有被处理 一些重要的定义： 在这本书中，它们第一次被使用，定义被以大写或印刷成黑体字的形式展示 环境是围绕在我们周围的物质生命的栖息地，在这儿我们能看到,听到,触摸,闻到,和品尝到 系统依据韦氏字典,被定义为“一组或一系列能形成一个整体或者有机整体的相互关联的事物”，例如，太阳系统，灌溉系统，供应系统，世界和宇宙。 污染被定义为“在大气，水或土地中的物质的，化学的或生物的特性的不合意的改变，这一改变有害地影响人类或其它生物的健康，生存，或活动”。 当改进环境质量的目标被用来改进人类福利，“环境”一词扩展成包括所有的社会，经济和文化方面的内容。这一扩展在许多真实情况下是不可行的以及在一本被设计为一学期课程的教科书中也是不实际的。我们对环境问题的考察因此限于我们对“环境”的定义。 系统的相互作用 许多不同的环境问题都与水，空气或土地系统有关联。许多这些问题都只适用于这些系统中的一个，这为这些种类中的细目分类提供了充分的理由。这样的分类也更有用于及易于理解一个系统内的相关问题。而且，这样做是明智的，这是因为由于管理上的和行政上的原因，这些有关空气污染，水供应，废水处理和固体废物处理的子域通常由政府机构分别处理。 很遗憾的是，很多重要的环境问题不仅仅限制于空气，水或土地系统，还包括系统间的相互作用。现在举个例子，酸雨问题起源于从发电站烟囱，冶炼厂和汽车尾气中向大气排放的含硫二氧化物和氮氧化物。接着这些气体由气流运输到广阔的区域，降雨“将它们洗去”，产生了有害于水生生命，森林和农作物的酸雨。两个有关于系统间相互作用引起的环境问题有：空气中的二氧化碳的增加的全球问题，及通常具有地域性质的酸雨问题。 环境问题 许多对我们生活标准的主要改进能被归因于科学和技术的运用。这里举一些例子，你能想出其它例子吗？ ●生产更多及更好质量的食物 ●创造能避免极端环境的保护所和生存空间 ●快速和可靠的运输方法的建立 ●各种交流系统的发明 ●代替人类和动物体力的机器的发明 ●安全水的供应和废物处理 ●对很多传染疾病的消除

英语原文 NUMERICAL CONTROL Numerical control(N/C)is a form of programmable automation in which the processing equipment is controlled by means of numbers, letters, and other symbols, The numbers, letters, and symbols are coded in an appropriate format to define a program of instructions for a particular work part or job. When the job changes, the program of instructions is changed. The capability to change the program is what makes N/C suitable for low-and medium-volume production. It is much easier to write programs than to make major alterations of the processing equipment. There are two basic types of numerically controlled machine tools：point—to—point and continuous—path(also called contouring).Point—to—point machines use unsynchronized motors, with the result that the position of the machining head Can be assured only upon completion of a movement, or while only one motor is running. Machines of this type are principally used for straight—line cuts or for drilling or boring. The N/C system consists of the following components：data input, the tape reader with the control unit, feedback devices, and the metal—cutting machine tool or other type of N/C equipment. Data input, also called “man—to—control link”,may be provided to the machine tool manually, or entirely by automatic means. Manual methods when used as the sole source of input data are restricted to a relatively small number of inputs. Examples of manually operated devices are keyboard dials, pushbuttons, switches, or thumbwheel selectors. These are located on a console near the machine. Dials ale analog devices usually connected to a syn-chro-type resolver or potentiometer. In most cases, pushbuttons, switches, and other similar types of selectors are digital input devices. Manual input requires that the operator set the controls for each operation. It is a slow and tedious process and is seldom justified except in elementary machining applications or in special cases. In practically all cases, information is automatically supplied to the control unit and the machine tool by cards, punched tapes, or by magnetic tape. Eight—channel punched paper tape is the most commonly used form of data input for conventional N/C systems. The coded instructions on the tape consist of sections of punched holes called blocks. Each block represents a machine function, a machining operation, or a combination of the two. The entire N/C program on a tape is made up of an accumulation of these successive data blocks. Programs resulting in long tapes all wound on reels like motion-picture film. Programs on relatively short tapes may be continuously repeated by joining the two ends of the tape to form a loop. Once installed, the tape is used again and again without further handling. In this case, the operator simply loads and

机械制造专业英语文章 篇一：机械专业英语文章中英文对照 Types of Materials 材料的类型 Materials may be grouped in several ways. Scientists often classify materials by their state: solid, liquid, or gas. They also separate them into organic (once living) and inorganic (never living) materials. 材料可以按多种方法分类。科学家常根据状态将材料分为：固体、液体或气体。他们也把材料分为有机材料(曾经有生命的)和无机材料(从未有生命的)。 For industrial purposes, materials are divided into engineering materials or nonengineering materials. Engineering materials are those used in manufacture and become parts of products. 就工业效用而言，材料被分为工程材料和非工程材料。那些用于加工制造并成为产品组成部分的就是工程材料。 Nonengineering materials are the chemicals, fuels, lubricants, and other materials used in the manufacturing process, which do not become part of the product. 非工程材料则是化学品、燃料、润滑剂以及其它用于加工制造过程但不成为产品组成部分的材料。 Engineering materials may be further subdivided into: ①Metal ②Ceramics ③Composite ④Polymers, etc. 工程材料还能进一步细分为：①金属材料②陶瓷材料③复合材料④聚合材料，等等。 Metals and Metal Alloys 金属和金属合金 Metals are elements that generally have good electrical and thermal conductivity. Many metals have high strength, high stiffness, and have good ductility. 金属就是通常具有良好导电性和导热性的元素。许多金属具有高强度、高硬度以及良好的延展性。 Some metals, such as iron, cobalt and nickel, are magnetic. At low temperatures, some metals and intermetallic compounds become superconductors. 某些金属能被磁化，例如铁、钴和镍。在极低的温度下，某些金属和金属化合物能转变成超导体。 What is the difference between an alloy and a pure metal? Pure metals are elements which come from a particular area of the periodic table. Examples of pure metals include copper in electrical wires and aluminum in cooking foil and beverage cans. 合金与纯金属的区别是什么？纯金属是在元素周期表中占据特定位置的元素。 例如电线中的铜和制造烹饪箔及饮料罐的铝。 Alloys contain more than one metallic element. Their properties can be changed by changing the elements present in the alloy. Examples of metal alloys include stainless steel which is an alloy of iron, nickel, and chromium; and gold jewelry which usually contains an alloy of gold
