(完整版)医学专业英语翻译及答案
Chapter 1 Passage 1 Human Body In this passage you will learn: 1. Classification of organ systems 2. Structure and function of each organ system 3. Associated medical terms To understand the human body it is necessary to understand how its parts are put together and how they function. The study of the body's structure is called anatomy; the study of the body's function is known as physiology. Other studies of human body include biology, cytology, embryology, histology, endocrinology, hematology, immunology, psychology etc. 了解人体各部分的组成及其功能，对于认识人体是必需的。研究人体结构的科学叫解剖学；研究人体功能的科学叫生理学。其他研究人体的科学包括生物学、细胞学、胚胎学、组织学、内分泌学、血液学、遗传学、免疫学、心理学等等。 Anatomists find it useful to divide the human body into ten systems, that is, the skeletal system, the muscular system, the circulatory system, the respiratory system, the digestive system, the urinary system, the endocrine system, the nervous system, the reproductive system and the skin. The principal parts of each of these systems are described in this article. 解剖学家发现把整个人体分成骨骼、肌肉、循环、呼吸、消化、泌尿、内分泌、神经、生殖系统以及感觉器官的做法是很有帮助的。本文描绘并阐述了各系统的主要部分。 The skeletal system is made of bones, joints between bones, and cartilage. Its function is to provide support and protection for the soft tissues and the organs of the body and to provide points of attachment for the muscles that move the body. There are 206 bones in the human skeleton. They have various shapes - long, short, cube - shaped, flat, and irregular. Many of the long bones have an interior space that is filled with bone marrow, where blood cells are made. 骨骼系统由骨、关节以及软骨组成。它对软组织及人体器官起到支持和保护作用，并牵动骨胳肌，引起各种运动。人体有206根骨头。骨形态不一，有长的、短、立方的、扁的及不规则的。许多长骨里有一个内层间隙，里面充填着骨髓，这即是血细胞的制造场所。 A joint is where bones are joined together. The connection can be so close that no movement is possible, as is the case in the skull. Other kinds of joints permit movement: either back and forth in one plane - as with the hinge joint of the elbow - or movement around a single axis - as with the pivot joint that permits the head to rotate. A wide range of movement is possible when the ball - shaped end of one bone fits into a socket at the end of another bone, as they do in the shoulder and hip joints. 关节把骨与骨连接起来。颅骨不能运动，是由于骨与骨之间的连接太紧密。但其它的关节可允许活动，如一个平面上的前后屈伸运动，如肘关节；或是绕轴心旋转运动，如枢轴点允许头部转动。如果一根骨的球形末端插入另一根骨的臼槽里，大辐度的运动（如肩关节、髋关节）即成为可能。 Cartilage is a more flexible material than bone. It serves as a protective, cushioning layer where bones come together. It also connects the ribs to the breastbone and provides a structural base for the nose and the external ear. An infant's skeleton is made of cartilage that is gradually replaced by bone as the infant grows into an adult. 软骨是一种比一般骨更具韧性的物质。它是骨连结的保护、缓冲层。它把肋骨与胸骨连结起来，也是鼻腔与内耳的结构基础。一个婴儿的骨骼就是由软骨组成，然后不断生长、

Lesson One: The Time Message Elwood N, Chapman 新的学习任务开始之际，千头万绪，最重要的是安排好时间，做时间的主人。本文作者提出了7点具体建议，或许对你有所启迪。 1 Time is tricky. It is difficult to control and easy to waste. When you look a head, you think you have more time than you need. For Example,at the beginning of a semester, you may feel that you have plenty of time on your hands, but toward the end of the term you may suddenly find that time is running out. You don't have enough time to cover all your duties (duty), so you get worried. What is the answer? Control! 译：时间真是不好对付，既难以控制好，又很容易浪费掉，当你向前看时，你觉得你的时间用不完。例如，在一个学期的开始，你或许觉得你有许多时间，但到学期快要结束时，你会突然发现时间快用光了，你甚至找不出时间把所有你必须干的事情干完，这样你就紧张了。答案是什么呢？控制。 2 Time is dangerous. If you don't control it, it will control you. I f you don't make it work fo r you, it will work against you. So you must become the master of time, not its servant. As a first-year college student, time management will be your number one Problem. 译：时间是危险的，如果你控制不了时间，时间就会控制你，如果你不能让时间为你服务，它就会起反作用。所以，你必须成为时间的主人，而不是它的奴仆，作为刚入学的大学生，妥善安排时间是你的头等大事。 3 Time is valuable. Wasting time is a bad habit. It is like a drug. The more time you waste,the easier it is to go on wasting time. If seriously wish to get the most out of college, you must put the time message into practice. 译：时间是珍贵的，浪费时间是个坏习惯，这就像毒品一样，你越浪费时间，就越容易继续浪费下去，如果你真的想充分利用上大学的机会，你就应该把利用时间的要旨付诸实践。 Message1. Control time from the beginning. 4 Time is today, not tomorrow or next week. Start your plan at the Beginning of the term. 译：抓紧时间就是抓紧当前的时间，不要把事情推到明天或是下周，在学期开始就开始计划。 Message2. Get the notebook habit. 5 Go and buy a notebook today, Use it to plan your study time each day. Once a weekly study plan is prepared, follow the same pattern every week with small changes. Sunday is a good day to make the Plan for the following week.

全新版大学英语综合教程2课文翻译
一单元One way of summarizing the American position is to state that we value originality and independence more than the Chinese do. The contrast between our two cultures can also be seen in terms of the fears we both harbor. Chinese teachers are fearful that if skills are not acquired early, they may never be acquired; there is, on the other hand, no comparable hurry to promote creativity. American educators fear that unless creativity has been acquired early, it may never emerge; on the other hand, skills can be picked up later. However, I do not want to overstate my case. There is enormous creativity to be found in Chinese scientific, technological and artistic innovations past and present. And there is a danger of exaggerating creative breakthroughs in the West. When any innovation is examined closely, its reliance on previous achievements is all too apparent (the "standing on the shoulders of giants" phenomenon). But assuming that the contrast I have developed is valid, and that the fostering of skills and creativity are both worthwhile goals, the important question becomes this: Can we gather, from the Chinese and American extremes, a superior way to approach education, perhaps striking a better balance between the poles of creativity and basic skills? 美国人的立场可以概括起来这么说，我们比中国人更重视创新和自立。我们两种文化的差异也可以从我们各自所怀的忧虑中显示出来。中国老师担心，如果年轻人不及早掌握技艺，就有可能一辈子掌握不了；另一方面，他们并不同样地急于促进创造力的发展。美国教育工作者则担心，除非从一开始就发展创造力，不然创造力就有可能永不再现；而另一方面，技艺可于日后获得。 但我并不想夸大其辞。无论在过去还是在当今，中国在科学、技术和艺术革新方面都展示了巨大的创造力。而西方的创新突破则有被夸大的危险。如果仔细审视任何一项创新，其对以往成就的依赖则都显而易见（“站在巨人肩膀之上”的现象）。 然而，假定我这里所说的反差是成立的，而培养技艺与创造力两者都是值得追求的目标，那么重要的问题就在于：我们能否从中美两个极端中寻求一种更好的教育方式，它或许能在创造力与基本技能这两极之间获得某种较好的平衡？ 三单元SEAN: If that sort of thing happened only once in a while, it wouldn't be so bad. Overall, I wouldn't want to trade my dad for anyone else's. He loves us kids and Mom too. But I think that's sometimes the problem. He wants to do things for us, things he thinks are good. But he needs to give them more thought because: SEAN, HEIDI and DIANE: (In unison) Father knows better! DIANE: Can you imagine how humiliated I was? An honor student, class president. And Father was out asking people to have their sons call and ask me to the prom! But that's dear old dad. Actually, he is a dear. He just doesn't stop to think. And it's not just one of us who've felt the heavy hand of interference. Oh, no, all three of us live in constant dread knowing that at any time disaster can strike because:肖恩：这类事要是偶尔发生一两次，那倒也没什么。总的来说，我是不肯把自己老爸跟别人的老爸换的。他爱我们当子女的，也爱老妈。不过我想，有时问题就出在这儿。他一心想帮助我们，他自以为在为我们做好事呢。可他应该多想想才对，因为：
力学专业英语部分翻译 孟庆元
1、应力和应变 应力和应变的概念可以通过考虑一个棱柱形杆的拉伸这样一个简单的方式来说明。一个棱柱形的杆是一个遍及它的长度方向和直轴都是恒定的横截面。在这个实例中，假设在杆的两端施加有轴向力F，并且在杆上产生了均匀的伸长或者拉紧。 通过在杆上人工分割出一个垂直于其轴的截面mm，我们可以分离出杆的部分作为自由体【如图1(b)】。在左端施加有拉力P，在另一个端有一个代表杆上被移除部分作用在仍然保存的那部分的力。这些力是连续分布在横截面的，类似于静水压力在被淹没表面的连续分布。 力的集度，也就是单位面积上的力，叫做应力，通常是用希腊字母，来表示。假设应力在横截面上是均匀分布的【如图1(b)】，我们可以很容易的看出它的合力等于集度，乘以杆的横截面积A。而且，从图1所示的物体的平衡，我们可以看出它的合力与力P必须的大小相等，方向相反。因此，我们可以得出 等式(1)可以作为棱柱形杆上均匀应力的方程。这个等式表明应力的单位是，力除以面积。当杆被力P拉伸时，如图所示，产生的应力是拉应力，如果力在方向是相反，使杆被压缩，它们就叫做压应力。 使等式(1)成立的一个必要条件是，应力，必须是均匀分布在杆的横截面上。如果轴向力P作用在横截面的形心处，那么这个条件就实现了。当力P没有通过形心时，杆会发生弯曲，这就需要更复杂的分析。目前，我们假设所有的轴向力都是作用在横截面的形心处，除非有相反情况特别说明。同样，除非另有说明，一般也假设物体的质量是忽略的，如我们讨论图1的杆
一样。 轴向力使杆产生的全部伸长量，用希腊字母δ表示【如图1(a)】，单位长度的伸长量，或者应变，可以用等式来决定。 L是杆的总长。注意应变ε是一个无量纲的量。只要应变是在杆的长度方向均匀的，应变就可以从等式(2)中准确获得。如果杆处于拉伸状态，应变就是拉应变，代表材料的伸长或者延长如果杆处于受压状态，那么应变就是压应变，这也就意味着杆上临近的横截面是互相靠近的。 当材料的应力和应变显示的是线性关系时，也就是线弹性。这对多数固体材料来说是极其重要的性质，包括多数金属，塑料，木材，混凝土和陶瓷。处于拉伸状态下，杆的应力和应变间的线性关系可以用简单的等式来表示。E是比例常数，叫做材料的弹性模量。 注意E和应力有同样的单位。在英国科学家托马斯·杨(1773 ~ 1829)研究杆的弹性行为之后，弹性模量有时也叫做杨氏模量。对大多数材料来说，压缩状态下的弹性模量与处于拉伸时的弹性模量的一样的。 2、拉伸应力应变行为 一个特殊材料中应力和应变的关系是通过拉伸测试来决定的。材料的试样通常是圆棒的形式，被安置在测试机上，承受拉力。当载荷增加时，测量棒上的力和棒的伸长量。力除以横截面积可以得出棒的应力，伸长量除以伸长发生方向的长度可以得出应变。通过这种方式，材料的完整应力应变图就可以得到。 图1所示的是结构钢的应力应变图的典型形状，轴向应变显示在水平轴，对应的应力以纵坐标表示为曲线OABCDE。从O点到A点，应力和应变之间是
