篇一：二年级英语小故事：两个口袋
【原文】The Two Bags
Every man carries Two Bags about with him, one in front and one behind, and both are packed full of faults. The Bag in front contains his neighbours’ faults, the one behind his own. Hence it is that men do not see their own faults, but never fail to see those of others.
【译文】两个口袋
每个人生来都带着两个口袋，一个在前，一个在后，两个口袋里都满载缺点。前面那只口袋里装的是别人的缺点，而后面那只口袋里则装满的是自己的缺点。因此，人们总是看不见自己的缺点，却永远也不会忽视去看别人的缺点。
篇二：二年级英语小故事：男孩和青蛙
【原文】The Boys And The Frogs
One spring day some naughty boys were playing near a pond. They began to throw stones into the water. In the pond lived many frogs were much afraid of the boys, for the stones hurt some of the frogs. At last an old frog lifted his head out of the water and said, ¨Boys, please dont throw stones at us.〃The boys said, ¨We are only playing.〃¨I know that, but please stop throwing stones, my boys. What is play to you is death to us,〃said the old frog. So the boys stopped throwing stones and went away.
【译文】男孩和青蛙
春天里的一天，一些顽皮的男孩在一个水塘边玩耍。他们开始往水里扔石块。许多生活在水塘里的青蛙非常害怕这些男孩，因为石头曾弄伤了他们中的一些。最后一只老青蛙把他的脑袋探出水面，他说：“孩子们，请别向我们扔石头。”男孩说：“我们只是在玩耍。”“我知道，但请别扔石头，孩子们。对你们而言的玩耍对我们可意味着死亡。”老青蛙说。因此男孩们不再扔石头并且离开了
篇三：二年级英语小故事：口渴的乌鸦
【原文】Thirsty Crow
The crow and the pitcher A crow felt very thirsty. He looked for water everywhere. Finally, he found a pitcher. But there was not a lot of water in the pitcher. His beak could not reach it. He tried again and again, but still could not touch the water. When he was about to give up, an idea came to him. He took a pebble
and dropped it into the pitcher. Then he took another and dropped it in. Gradually, the water rose, and the crow was able to drink the water.
【译文】口渴的乌鸦
一只乌鸦口渴了，到处找水喝。终于，他找到了一个大水罐。然而，水罐里面的水并不多，他的尖嘴够不到水面，他试了一次又一次，都没有成功。就在他想放弃的时候，他突然想到一个主意。乌鸦叼来了一块小石子投到水罐里，接着又叼了一块又一块石头放进去。渐渐地，水面升高了。乌鸦高兴地喝到了水。
寓意:?有些东西虽然看起来微不足道，但如果积少成多，便会带来很大变化。
篇四：二年级英语小故事：狐狸和葡萄
【原文】Fox and the Grapes
One hot summer day a fox was walking through an orchard. He stopped before a bunch of grapes. They were ripe and juicy.
"I'm just feeling thirsty," he thought. So he backed up a few paces, got a running start, jumped up, but could not reach the grapes.
He walked back. One, two, three, he jumped up again, but still, he missed the grapes.
The fox tried again and again, but never succeeded. At last he decided to give it up.
He walked away with his nose in the air, and said“I am sure they are sour.”
【译文】狐狸和葡萄
一个炎热的夏日，狐狸走过一个果园，他停在一大串熟透而多汁的葡萄前。
狐狸想：“我正口渴呢。”于是他后退了几步，向前一冲，跳起来，却无法够到葡萄。
狐狸后退又试。一次，两次，三次，但是都没有得到葡萄。
狐狸试了一次又一次，都没有成功。最后，他决定放弃，他昂起头,边走边说：“葡萄还没有成熟，我敢肯定它是酸的。”
寓意:?在经历了许多尝试而不能获得成功的时候，有些人往往故意轻视成功，以此来寻求心理安慰。
篇五：二年级英语小故事：狼和羊
【原文】The wolf and the sheep
A wolf had been badly wounded by dogs. He lay sick and maimed in his lair. He felt very hungry and thirsty. When a sheep passed
by, he asked him to fetch some water from the stream.
"If you bring me the water," he said, "I will find means to get some food." "Yes," said the sheep, "if I bring you the water, you would undoubtedly make me your food."
【译文】狼和羊
狼被狗所咬，伤势很严重，痛苦地躺在巢穴里，不能外出觅食。他感到又饿又渴，这时，他看见一只羊，便请求他到附近的小河里为他取一点水来。
“你给我一点水解渴”，他说，“我就能自己去寻找食物了。”“是呀”，羊回答说，“如果我给你送水喝，那么我就会成为你的食物。”
寓意: 谎言是经不起推敲的，它很容易被人们识破。
篇六：二年级英语小故事：狐狸和公鸡

V. Reading Comprehension (15%) A It was 3.21 a. m. when nine-year-old Glenn Kreamer awoke to the smell of burning. Except for the crackling （爆裂声）of flames somewhere below there was not a sound in the two-storey house at Baldwin, Long Island. With his father away on night duty at a local factory, Glenn was worried about the safety of his mother, his sister Karen, 14 and his 12-year-old brother Todd. He ran downstairs through the smoke-filled house to push and pull at Karen and Todd until they sat up. Then he helped each on through the house to the safety of the garden. There, his sister and brother, taking short and quick breaths and coughing, collapsed on the lawn. The nine-year-old raced back into the house and upstairs to his mother's room. He found it impossible to wake her up. Mrs. Kreamer, a victim of the smoke, was unconscious, and there was nobody to help Glenn carry her to the garden. But the boy remained calm and, as a fireman said later, "acted with all the self-control of a trained adult." On the bedroom telephone, luckily still working, Glenn called his father and, leaving Mr. Kreamer to telephone the fire brigade and ambulance service, got on with the task of saving his mother. First he filled a bucket with water from the bathroom and threw water over his mother and her bed. Then, with a wet cloth around his head he went back to the garden. He could hear the fire engine coming up, but how would the firemen find his mother in the smoke-filled house where flames had almost swallowed up the ground flo or? Grasping firmly a ball of string from the garage, Glenn raced back into the house and dashed upstairs to his mother's room. Tying one end of the string to her hand he ran back, laying out the string as he went, through the hall and back out into the ga rden. Minutes later he was telling fire chief John Coughlan :"The string will lead you to mother." Mrs. Kreamer was carried to safety as the flames were breaking through her bedroom floor. 71．Why did Glenn run downstairs first? A．He wanted to find out what was happening. B．He was worried about his mother's safety.
《分析化学》专业英语阅读材料03
《分析化学》阅读材料03 摘自Analytical Chemistry (FECS) ●In the Br?sted-Lowry theory, an acid is a proton donor and a base is a proton acceptor. Each acid is related to its conjugate base and vice versa: Acid = base + proton Therefore, the conjugate base of a strong acid must be a weak base and the conjugate base of a weak acid must be a strong base. Together they form a couple, and an acid without its conjugate base is a meaningless concept. In order to release a proton, the acid must find a base to accept it. In an aqueous solution, the proton, H+, having an extremely small ionic radius, cannot exist as such. It is hydrated, forming the hydronium ion H3O+ and higher hydrates. Thus, an acid-base equilibrium is not a simple dissociation equilibrium, but the result of a proton transfer reaction in which there are at least two reagents and two products. Such a process is also called protolysis. The overall reaction is expressed by: HX + H2O = H3O+ + X-. The overall equilibrium constant is K = [H3O+][X-]/[HX][H2O]. The acid dissociation constant Ka is given by: Ka = K[H2O] = [H3O+][X-]/[HX]. Ka reflects not only the acid strength of HX, but also the base strength of water. This why different acid dissociation constants are observed for the same acid in different solvent. ●Similar proton transfer reactions exist in all solvents possessing proton donor and acceptor properties. Proton transfer reactions are extremely fast. This makes them very suitable for analytical applications and acid-base reactions have found wide use in volumetric methods and other analytical techniques. ●The pH value is a measure for the acidity or basicity of a solution, aqueous or nonaqueous. ●Acid-base indicators are chemical substances with acid-base properties, having different colors in their protonated and deprotonated forms. ● A most important application of acid-base systems is related to the property of such a system to act as a buffer. Many chemical reactions produce protons (in aqueous solutions hydroniums) or hydroxide ions. If these products remain in the system, a corresponding pH change is observed. However, if a buffer is present in the solution it reacts with the liberated hydrogen or hydroxide ions so that only a relative small change of pH occurs. Buffer consist of a mixture of a weak acid and its conjugate base. The most efficient buffer for a given pH consists of a 1:1 ratio of the protonated and deprotonated forms of a weak acid (with pKa = pH). This cannot always be achieved, but if we wish to prepare a solution of a certain pH, we select a weak acid with a pKa value close to the desired pH. Buffer solution resists changes in pH upon adding of strong acids or strong bases. Depending on the relative concentrations of the acid and base forms of the buffer, the system can resist small or large additions of strong acid or base. This buffer capacity is defined as the number of moles of strong acid of base required to change the pH of 1 L of buffer solution by one pH unit. Solutions with high or low pH values, formed as a result of dissolution of large quantities of a strong base or acid, are characterized by a large buffer capacity, although the electrolyte practically consists of only one of the conjugate forms (e.g., HCl or NaOH solutions). ● A general requirement for all volumetric methods is that the titration process is fast and that it proceeds in a definite stoichiometric ratio, the endpoint of the reaction must by easy to detect and the reaction should be specific and not influenced by other constituents of the solution, i.e., there should be no interference. Question: 1. A H3PO4 solution is brought to pH = 7.00 by the addition of NaOH. Calculate the concentration of the various forms of orthophosphate if the total phosphate concentration in buffer is 0.200 mol /L. pKa1 = 2.16, pKa2 = 7.21, pKa3 = 12.32. 2. A buffer solution is prepared from acid, HA, Ka = 5 10-5, and its salt. The concentration of HA in the buffer is 0.25 mol / L. To 100 mL of the buffer added 5.0 mmol of NaOH, and the pH of the resulting solution is 5.60. What was the pH of the original buffer? 3.It is desired to change the pH of 100 mL of 0.100 mol / L HCl from 1.00 to 4.40 by the addition of sodium acetate, CH3COONa3H2O. How much solid sodium acetate salt must be added in grams? Assume no volume change for the solution as the result of the addition. 4.What is the buffer capacity of a solution which is 0.100 mol / L of NH3 and 0.200 of NH4Cl? 5.Calculate the pH of each of the following solution: (a) Water in equilibrium with CO2 of the air; pKa1 = 6.38, pKa2 = 10.25. (b) Water as in part (a) brought to pH = 7.00 with NaOH and allowed to regain equilibrium with CO2. 6. Derive the following expression for the pH at the first stoichiometric point in the titration of a mixture of two weak acid: HA, the stronger, Ka1, concentration C1; HB, the weaker, Ka2, concentration C2: pH = 1/2 (pKa1 + pKa2) – 1/2 lg (C1/C2)

Stephen is trying to find the answers to some very big questions, such as: how did the universe being? How will it end? 斯蒂芬在1942年出生。他是研究空间和时间领域的一位举世闻名的科学家和专家。斯蒂芬设法发现一些非常大问题的答案，例如：宇宙未来会怎样？它会怎样结束？ Stephen was a student at Oxford University. He studied math and science. Then, at the age of twenty, he became very ill. He was so young, but the doctor said to his family, “He has only two years to live.” The doctors were wrong-he didn’t die. He can’t walk now but he uses a wheelchair. He talks with the help of a computer. After Oxford, Stephen went to Cambridge University. Three years later, in 1963, he became a doctor of philosophy. 斯蒂芬曾经是牛津大学的学生。他学习数学和科学。然而，在20岁时，他生病了。他是如此年轻，但医生告诉他的家人，“他只活两年。”医生是错误的，他没有死。他现在虽然不能走路，但他可以使用了轮椅。随着计算机的帮助，他可以通过计算机举行会谈。牛津大学毕业后，斯蒂芬前往剑桥大学学习。3 年后，在1963年，他成为哲学博士。 Because of his health problems, it was difficult for him to draw diagrams or to write. So he started to think in pictures. With this new way of thinking, he became one of the most famous scientists in the world. In 1981, he met Pope in Rome. They talked about his ideas. Then, in 1988, he wrote his first important book, A Brief History of Time. It sold more than 5.5 million copies in 33 different countries. 由于他的健康问题，出图或写作对于他是很难的。因此他在图片上开始思考。这种新的思维方式，使他在世界上成为了一位最著名的科学家。在1981年，他在罗马遇见了教皇。他们谈论了他的想法。然后，在1988年他写了他的第一本重要的书，《时间的简史》。它在33个不同国家卖了超过550万本。 （2）说明文 One type of solar collector is not very expensive. It is put on the roof of a building. It is usually put on the sunny side of the roof. The sun is most direct in this side, and the unit will collect more heat. The surface is black because black collects more heat from the sun. Inside, there are pipes with water. The top is a piece of glass. The sun shines through the glass and air inside. It heats the water that is also inside. A pump, a machine to move the water, starts when water is warm enough. Then hot water goes into a storage tank. This tank stores or keeps the hot water. Then there is hot water to use for washing clothes or taking baths and showers.

It was not until in my late thirties that I made this important discovery： giving-away makes life so much more exciting. You need not worry if you lack money. This is how I experimented with giving-away. If an idea for improving the window display of a neighborhood store flashes to me, I step in and make the suggestion to the storekeeper. One discovery I made about giving-away is that it is almost impossible to give away anything in this world without getting something back, though the return often comes in an unexpected form. One Sunday morning the local post office delivered an important special delivery letter to my home, though it was addressed to me at my office. I wrote the postmaster a note of appreciation. More than a year later I needed a post-office box for a new business I was starting. I was told at the window that there were no boxes left, and that my name would have to go on a long waiting list. As I was about to leave, the postmaster appeared in the doorway. He had overheard our conversation. “Wasn’t it you that wrote us that letter a year ago about delivering a special delivery to your home?” I said yes. “Well, you certainly are going to have a box in this post office if we have to make one for you. You don’t know what a letter like that means to us. We usually get nothing but complaints.” 像绝大部分人，我长大看待生命是一个过程获得。直到我在30月底，我作出这个重要发现：给予，距离使我们的生活如此更令人兴奋的。您不必担心如果缺乏资金。这是我尝试让-消失。如果一个主意，

UNIT 1 一、材料根深蒂固于我们生活的程度可能远远的超过了我们的想象，交通、装修、制衣、通信、娱乐（recreation）和食品生产，事实上（virtually），我们生活中的方方面面或多或少受到了材料的影响。历史上，社会的发展和进步和生产材料的能力以及操纵材料来实现他们的需求密切（intimately）相关，事实上，早期的文明就是通过材料发展的能力来命名的（石器时代、青铜时代、铁器时代）。 二、早期的人类仅仅使用（access）了非常有限数量的材料，比如自然的石头、木头、粘土（clay）、兽皮等等。随着时间的发展，通过使用技术来生产获得的材料比自然的材料具有更加优秀的性能。这些性材料包括了陶瓷（pottery）以及各种各样的金属，而且他们还发现通过添加其他物质和改变加热温度可以改变材料的性能。此时，材料的应用（utilization）完全就是一个选择的过程，也就是说，在一系列有限的材料中，根据材料的优点来选择最合适的材料，直到最近的时间内，科学家才理解了材料的基本结构以及它们的性能的关系。在过去的100年间对这些知识的获得，使对材料性质的研究变得非常时髦起来。因此，为了满足我们现代而且复杂的社会，成千上万具有不同性质的材料被研发出来，包括了金属、塑料、玻璃和纤维。 三、由于很多新的技术的发展，使我们获得了合适的材料并且使得我们的存在变得更为舒适。对一种材料性质的理解的进步往往是技术的发展的先兆，例如：如果没有合适并且没有不昂贵的钢材，或者没有其他可以替代（substitute）的东西，汽车就不可能被生产，在现代、复杂的（sophisticated）电子设备依赖于半导体（semiconducting）材料四、有时，将材料科学与工程划分为材料科学和材料工程这两个副学科（subdiscipline）是非常有用的，严格的来说，材料科学是研究材料的性能以及结构的关系，与此相反，材料工程则是基于材料结构和性能的关系，来设计和生产具有预定性
