页脚 Unit 1 The Roots of Chemistry I. Comprehension. 1.C 2. B 3. D 4. C 5. B
II. Make a sentence out of each item by rearranging the words in brackets. 1. The purification of an organic compound is usually a matter of considerable difficulty, and it is necessary to employ various methods for this purpose. 2. Science is an ever-increasing body of accumulated and systematized knowledge and is also an activity by which knowledge is generated. 3. Life, after all, is only chemistry, in fact, a small example of chemistry observed on a single mundane planet. 4. People are made of molecules; some of the molecules in people are rather simple whereas others are highly complex. 5. Chemistry is ever present in our lives from birth to death because without chemistry there is neither life nor death. 6. Mathematics appears to be almost as humankind and also permeates all aspects of human life, although many of us are not fully aware of this.
III. Translation. 1. (a) chemical process (b) natural science (c) the technique of distillation 2. It is the atoms that make up iron, water, oxygen and the like/and so on/and so forth/and otherwise. 3. Chemistry has a very long history, in fact, human activity in chemistry goes back to prerecorded times/predating recorded times. 4. According to/From the evaporation of water, people know/realized that liquids can turn/be/change into gases under certain conditions/circumstance/environment. 5. You must know the properties of the material before you use it.
IV. Translation 化学是三种基础自然科学之一，另外两种是物理和生物。自从宇宙大爆炸以来，化学过程持续进行，甚至地球上生命的出现可能也是化学过程的结果。人们也许认为生命是三步进化的最终结果,第一步非常快,其余两步相当慢。这三步是：（I）物理进化（化学元素的产生），（II）化学进化（分子和生物分子的形成）；和（III）生物进化（有机物的形成和发展）。
V. Solution: （1）The relative mass of 1H and 12C atoms can be calculated from their absolute masses in grams. 页脚
1241223H1.6735100.083986C1.992610
If the mass of a 12C atom is exactly 12 amu,then the mass of a 1H atom to five significant figures must be 1.0078 amu. 12 amu x 0.083986 = 1.0078 amu
（2） First we calculate k and then use the first-order rate equation.
404340.6931.2110/5730log2.3031.0001.2110/log0.4772.3032.303log2.096.11061001.2110/kyryrAktAyrttyryr
The bone was tossed away (more precisely, the animal whose bone was died) about 6100 years ago, or about 4100 B.C. We can thus be sure that a village was in existence at that place at that time.

For example, electronic sensors mounted in your car can detect alcohol vapor in the air and refuse to start up the engine. They can also monitor road conditions by receiving radio signals sent out from orbiting satellites and greatly reduce your chances of getting stuck in traffic jams.全新版大学英语综合教程(第二版)4第四册课后习题Unit 2 Part II Text Alexf OrganizationParts Paragraphs Main IdeasPart One Paras 1-2 Introduction — Both Napoleons and Hitlers military campaigns failed because of the severity of the Russian winter.Part Two Paras 3-11 Napoleons military campaign againstRussiaPart Three Paras 12-20 Hitlers military campaign against theSoviet UnionPart Four Para 21 Conclusion—the elements of nature must be rekoned with in any military campaign.2.Sections Paragraphs Main IdeasSection One Paras 12-13 Hitlers blitzkrieg againstRussiaand Stalins scorched earth policySection Two Paras 14-18 the battles foughtatLeningrad,MoscowandStalingradSection Three Paras 19-20 the Russian counter-offensive and the outcome of the warVocabularyI. 1. 1) alliance 2) at the cost of3) stroke 4) limp5) minus 6) regions7) declarations 8) siege9) raw 10) bide his time11) have taken their toll 12) in the case of2. 1) is faced with 2) get bogged down3) is pressing on / pressed on 4) drag on5) get by 6) dine out7) have cut back 8) get through3. 1) The rapid advance in gene therapy may lead to the conquest of cancer in the near future.2) Production in many factories has been brought to a halt by the delayed arrival of raw materials due to the dock workers strike3) Sara has made up her mind that her leisure interests will/should never get in the way of her career.4) Obviously the reporters question caught the foreign minister off guard.5) The introduction of the electronic calculator has rendered the slide rule out of date /obso lete.4. 1) Being faced with an enemy forces much superior to ours, we had to give up the occupation of big cities and retreat to the rural and mountainous regions to build up our bases.2) Unity is crucial to the efficient operation of an organization.

With more and more donations coming in, our university will be much better off financially next year. We will thus be able to focus on the most important task that we, educators, must take on: to encourage students to attain their scholarly/academic goals, to train them to be dependable and responsible individuals, to prepare them for the life ahead, and to guide them in their pursuit of spiritual as well as material satisfaction.

To improve our English, it is critical to do more reading, writing, listening and speaking. Besides, learning by heart as many well-written essays as possible is also very important. Without an enormous store of good English writing in your head you cannot express yourself freely in English. It is also helpful to summarize our experience as we go along, for in so doing, we can figure out which way of learning is more effective and will produce the most desirable result. As long as we keep working hard on it, we will in due course accomplish the task of mastering English.

全新版大学英语（第二版）课后翻译答案（精选多篇）第一篇：全新版大学英语(第二版)课后翻译答案1.The offensive had already lasted three days, but we had not gained much ground.The division commander instructed our battalion to get around to the rear of the enemy at night and launch a surprise attack.To do so, however, we had to cross marshland and many of us were afraid we might get bogged down in the mud.Our battalion commander decided to take a gamble.Lucky enough, thanks to the severely cold weather which made the marshland freeze over, we arrived at our destination before dawn and began attacking the enemy from the rear.This turned the tide of the battle.The enemy, caught off guard, soon surrendered.2.Automobiles have, since their invention, revolutionized transportation, changing forever the way people live, travel, and do business.On the other hand, they have brought hazards, especially highway fatalities.However, today the application of computer technology and electronic sensors in designing and manufacturing cars makes it possible to eliminate most of traffic accidents.For example, electronic sensors mounted in your car can detect alcohol vapor in the air and refuse to start up the engine.They can also monitor road conditions by receiving radio signals sent out from orbiting satellites and greatly reduce.4.Globalization has great implications for young Chinese.For example, young farmers are moving on a large scale to urban areas to look for jobs.And for those young people who aspire to study abroad or work in foreign-invested enterprises, English has become increasingly important.At the same time, a considerable number of overseas Chinese students have returned home in recent years, for they hold an optimisticoutlook for the long-term growth of the Chinese economy.The internet has strengthened the links between Chinese young people and those elsewhere.They follow the latest trend and copy foreign fashions.Some of them don’t seem to care for traditional Chinese virtues, let alone carry them forward, which has given rise to worries that the traditional Chinese culture might one day vanish.5.For my own part, I find that appearances are all too often deceptive.For instance, you might be wrong if you judged by appearances only people like Edward Hyde Burton.In appearance, he seemed a man all of a piece.He was a tiny little fellow with white hair and mild blue eyes, gentle and candid.Nevertheless, he turned out to be very cruel.He insulted and fooled Lenny who was down and out and made him commit himself to an insane venture.What was still more surprising was that he was completely indifferent to Lenny’s death.Without doubt, Burton was a man with a heart of stone.6.Today we are under constant pressure to work longer hours, to produce more, and to possess more.Lots of people hold the wrong perception that happiness lies in working hard and earning money.Many women today feel the same stress to work and get ahead and, at the same time, to nurture their offspring and shoulder the burden of domestic responsibilities.Research shows that workaholism tends to distance us from our immediate families.It forces us to toil longer and longer hours, leaving a minute fraction of our time to be physically and emotionally available to our loved ones.Intimacy among family members is doomed to die in the process.第二篇：全新版大学英语三(第二版)课后翻译翻译1、我们的计算机系统出了毛病，但我觉得问题比较小。

Unit1 Part 1谢谢您带给我们多年来最畅快的欢笑1 最近一个周末，有位女士在大西洋城玩老虎机，赢了满满一桶二十五美分的硬币。
她暂时离开赌博机，与丈夫前往旅馆餐厅吃晚饭。
2 不过，她想先去客房把硬币藏起来。
“我去一会儿就回来，然后我们再去吃饭。
”她对她的丈夫说道，之后，便提着满满一桶硬币朝电梯走去。
3 她正要走进电梯时，看到电梯里已经有两位男乘客。
两位都是黑人，其中一位个头很高，体型令人望而生畏。
这位女士一下子愣住了。
她的第一反应是：“这两个男人会打劫我。
”她转而又想：“不要戴着‘有色眼镜’看人；他们看上去完全像是绅士。
”然而，种族偏见的力量是强大的，恐惧使她浑身发凉。
她定在那里，眼睛紧盯着眼前两位男子。
4 她开始焦虑，心神不定，又感到不好意思。
她希望他们没有看出她的心思，但是，天啊，他们肯定已经知道她在琢磨什么了！5 要不要进去和他们同乘一部电梯？她迟疑不决的态度已经太过明显了。
她涨得满脸通红。
老站着不动也无济于事，于是她横下心来，抬起一只脚往前挪，接着另一只脚也跟了进来，站在电梯内。
她不敢抬眼，僵直地转过身，脸朝外，这时，电梯门合上了。
时间一秒一秒地过去。
她越来越害怕！电梯纹丝不动。
她陷入了恐惧的深渊。
“我的天啊，”她暗忖，“我被困在这里，要遭人劫财！”她的心往下沉，每个毛孔都在冒汗水。
6 这时，她听到其中一个人说：“趴下（与“按下楼层”同音）。
”她的本能反应就是照着他们的话做。
于是她张开双臂，趴在了电梯地板上，满桶的硬币飞向空中，洒了出去。
硬币如雨点般落在了她的身上。
她在心里默祷：“把钱拿去吧，饶我一命。
”又过了几秒钟，她听到其中一位男子彬彬有礼地说：“夫人，您只要告诉我您要去几楼，我们来按按钮。
”说这话的人有点费力才把话说完，尽力忍住没有放声大笑。
7 这位女士抬起头望着这两位男乘客。
他们弯下腰，把她搀扶起来。
她满腹疑惑，挣扎着站了起来。

应用化学专业英语 Lesson 28 翻译
Lesson 28 A Experiment Ease: Synthesis ofSalicylic AcidFrom Oil of Wintergreen (MethylSalicylate)overviewMethyl salicylate (水杨酸酯) (oil of wintergreen) and salicylic acid (水杨酸) are naturally occurring compounds with medicinal uses. You will try to prepare salicylic acid by boiling methyl salicylate with aqueous sodium hydroxide(lye 碱液). You will also try to purify your product by recrystallization (再结晶) and characterize it by measuring its melting temperature.Time require:2 laboratory sessions.Background Methyl salicylate and salicylic acid are naturally occurring compounds with medicinal uses. The procedure used here to convert methyl salicylate into salicylic acid is called saponification (皂化)。
It is chemically related to the process used to convert natural fats into soap. Salicylic acid and aspirin Many plants produce salicylic acid naturally. Among these, willow trees (柳树) have been recognized since antiquity as a potent (有效) source of medicine. Hippocrates (一个希腊的名医) encouraged the pregnant women of ancient Greece to chew willow leaves and drink willow tea to alleviate (减轻) labor and birth pains. Chinese, Native Americans, and others also used willow. Salicylic acid is found mainly in the willo w’s leaves and bark (树皮).The pure acid possesses several useful medicinal properties. It is an antipyretic (a fever reducer), an analgesic (a pain reducer), and an anti-inflammatory (a swelling reducer). Unfortunately, pure salicylic acid and even the concoctions (混合物) derived from willow, make for an extremely unpleasant medicine. The salicylic acid molecule contains two acidic functional groups, the phenol group (PhOH) and the carboxylic acid group (-COOH). These groups make salicylic acid an irritating (刺激性的) substance that burns the sensitive linings of the mouth, throat, esophagus (食道)， and stomach. [Interestingly, salicylic acid’s ability to burn living tissue28课 一个实验案例：从冬青油（水杨酸酯）中合成水杨酸概述水杨酸酯（冬青油）和水杨酸是常用于药物合成的天然物质。
