Unit 1 恰到好处你见过一个笨手笨脚的男人往箱子上钉钉子吗？只见他左敲敲，右敲敲，说不准还会将整个钉子锤翻，结果敲来敲去到头来只敲进了半截。
而娴熟的木匠就不这么干。
他每敲一下都会坚实巧妙地正对着钉头落下去，一钉到底。
语言也是如此。
一位优秀的艺术家谴词造句上力求准确而有力地表达自己的观点。
差不多的词，不准确的短语，摸棱两可的表达，含糊不清的修饰，都无法使一位追求纯真英语的作家满意。
他会一直思考，直至找到那个能准确表达他的意思的词。
法国人有一个很贴切的短语来表达这样一个意思，即“le m ot juste”, 恰到好处的词。
有很多关于精益求精的作家的名人轶事，比如福楼拜常花几天的时间力求使一两个句子在表达上准确无误。
在浩瀚的词海中，词与词之间有着微妙的区别，要找到能恰如其分表达我们意思的词绝非易事。
这不仅仅是扎实的语言功底和相当大的词汇量的问题，还需要人们绞尽脑汁，要观察敏锐。
选词是认识过程的一个步骤，也是详细描述我们的思想感情并表达出来使自己以及听众和读者深刻理解的一个环节。
有人说：“在我思想未成文之前，我怎么知道自己的想法？”这听起来似乎很离谱，但它确实很有道理。
寻找恰如其分的词的确是件不容易的事。
一旦找到了那个词，我们就会感到很欣慰：辛劳得到了回报。
准确地用语言有助于我们深入了解我们描述的事物。
例如，当有人问你：“某某是怎么样的人？”你回答说：“恩，我想他是个不错的家伙，但他非常……”接着你犹豫了，试图找到一个词或短语来说明他到底讨厌在哪里。
当你找到一个恰当的短语的时候，你发觉自己对他的看法更清楚，也更精确了。
一些英语词汇词根相同而意义却截然不同。
例如human 和humane,二者的词根相同，词义也相关，但用法完全不同。
“ human action (人类行为)”和“humane action ( 人道行为)”完全是两码事。
我们不能说“人道权力宣言”，而是说“人权宣言”。
有一种屠杀工具叫“humane killer ( 麻醉屠宰机)，而不是human killer ( 杀人机器)。

Lesson Five
Lesson FiveThe Schrodinger equation is a differential equation, which means that solution of it are themselves equations, but the solutions are not differential equations. They are simple equations for which graphs can be drawn. Such graphs, which are three—dimensional pictures that show the electron density, are called orbitals or electron cloud. Most students are familiar with the shapes of s and p atomic orbitals. Note that each p orbital has a node—a region in space where the probability of finding the electron is extremely small. Also note that some lobes of the orbitals are labeled plus (+) and others minus (--). These signs do not refer to positive or negative charges, since both lobes of an electron cloud must be negatively charged. They are the signs of the wave function ψ. When two parts of an orbital are separated by a node, ψalways has opposite sign on the two sides of the node. According to the Pauli exclusion principle, no more than two electrons can be present in any orbital, and they must have opposite spins.Unfortunately, the Schrodinger equation can be solved exactly only for one electron systems such as the hydrogen atom. If it could be solved exactly for molecules containing two or more electrons, we could have a precise picture of the shape of the orbitals available to each electron (especially for the important ground state) and the energy for each orbital. Since exact solutions are not available, drastic approximations must be made. There are two chief general methods of approximation: the molecular orbital (MO) method and the valence bond (VB) method.In the MO method, bonding is considered to arise from overlap of atomic orbitals. When any number of atomic orbitals overlap, they combine to form an equal number of new orbitals, called molecular orbitals. Molecular orbitals differ from atomic orbital in that they are clouds that surround the nuclei of two or more atoms, rather than just one atom. In localized bonding, the number of atomic orbitals that overlap is two (each containing one electron), so that two molecular orbitals are generated. One of these, called a bonding orbital, has a lower energy than the original atomic orbitals (otherwise a bond would not form), and the other, called an antibonding orbital, has a higher energy. Orbital of lower energy fill first. Since the two original atomic orbitals each held one electron, both of these electrons can now go into the new molecular bonding orbital, since any orbital can hold two electrons. The antibonding orbital remains empty in the ground state. The greater the overlap, the stronger the bond, although total overlap is prevented by repulsion between the nuclei. Note that since the antibonding orbital has a node between the nuclei, there is practically no electron density in that area, so that this orbital cannot be expected to bond very well. Molecular orbitals formed by the overlap of two atomic orbitals when the centers of electron density are on the axis common to the two nuclei are called σ(sigma) orbitals, and the bonds are calledσbonds. Corresponding antibonding orbitals are designatedσ★. Sigma orbitals are formed not only by the overlap of two s orbitals, but also by the overlap of any of the kinds of atomic orbitals(s, p, d, f) whether the same or different, but the two lobes that overlap must have the same sign: A positive s orbital can form a bond only by overlapping with another positive s orbital or with a positive lobe of a p, d, or f orbital. Any s orbital, no matter what kind of atomic orbitals it has arisen from, may be represented as approximately ellipsoidal in shape.Orbital are frequently designated by their symmetry properties. Theσorbital of hydrogen is often writtenψg. The g stands for gerade. A gerade orbital is one in which the sign on the orbital dose not change when it is inverted though its center of symmetry. Theσ★orbital is ungerade (designated ψu). An ungerade orbital change sign when inverted though its center of symmetry.。

牛津六下英语5单元课文鲁班造锯
牛津六下英语5单元课文鲁班造锯Intrigued by the enigmatic figure of Luban and his ingenious invention, the handsaw, I embark on a captivating journey to unravel the rich tapestry of his remarkable life and the lasting impact of his pioneering creation. Delving into the historical narratives that have been passed down through the generations, I aim to paint a vivid portrait of this remarkable individual, his innovative spirit, and the enduring legacy he has left upon the world.Luban, a revered figure in Chinese history, was a visionary architect, engineer, and inventor who lived during the Spring and Autumn period (approximately 770-476 BCE). Born in the ancient state of Lu, located in present-day Shandong province, Luban's life was marked by a relentless pursuit of knowledge and a profound dedication to solving the practical challenges of his time.From a young age, Luban demonstrated a keen intellect and an insatiable curiosity, traits that would shape the trajectory of his remarkable career. Drawn to the realms ofarchitecture and engineering, he honed his skills through rigorous study and hands-on experimentation, constantly seeking to push the boundaries of what was deemed possible.One of Luban's most celebrated achievements was the invention of the handsaw, a tool that revolutionized the way in which wood was cut and shaped. Prior to Luban's innovation, the process of cutting timber was a laborious and imprecise endeavor, often relying on crude tools and brute force. Recognizing the need for a more efficient and versatile solution, Luban set out to design a tool that would forever change the landscape of carpentry and construction.Through his meticulous observations and ingenious problem-solving skills, Luban developed the handsaw, a simple yet ingenious device that allowed for the precise andeffortless cutting of wood. The key innovation lay in the design of the saw's teeth, which Luban meticulously crafted to maximize the tool's efficiency and precision. By carefully angling and sharpening the teeth, Luban ensured that the saw could easily slice through even the moststubborn of timber, with minimal effort and waste.The impact of Luban's invention cannot be overstated. The handsaw, in its various iterations and refinements, became an indispensable tool for artisans, carpenters, andbuilders across China and beyond. It facilitated the construction of intricate and elaborate structures, from grand palaces to humble dwellings, and played a crucialrole in the development of the country's architectural and engineering prowess.But Luban's contributions extended far beyond the realm of the handsaw. He was a prolific inventor and problem-solver, constantly seeking to address the practical needs of his time. One of his other renowned inventions was the windlass, a device that revolutionized the way in which heavy objects could be lifted and transported. This ingenious mechanism, which utilized the power of wind to aid in the movement of large and cumbersome loads, greatly enhanced the efficiency of construction and transportation projects throughout ancient China.Luban's innovative spirit was not limited to the physical realm; he was also a gifted architect and designer, responsible for the creation of numerous iconic structures that continue to captivate and inspire to this day. His masterful understanding of spatial dynamics, structural integrity, and aesthetic principles led to the construction of awe-inspiring palaces, temples, and public spaces that seamlessly blended form and function.One of Luban's most renowned architectural achievements was the design of the Tianwang Hall, a grand and imposing structure that served as the centerpiece of the Daming Palace complex in the ancient capital of Chang'an (present-day Xi'an). This magnificent edifice, with its towering columns, intricate carvings, and harmonious proportions, stood as a testament to Luban's genius and the advanced state of Chinese architecture during his time.Beyond his technical and creative accomplishments, Luban was also revered for his profound wisdom and philosophical insights. He was considered a sage and a mentor, respected by both the commoners and the ruling elite for his deepunderstanding of the natural world, the principles of harmony, and the nature of human existence.Luban's teachings and principles were recorded and passed down through the generations, influencing the thought and practices of countless individuals across China. His emphasis on the importance of balance, the harmony between humans and nature, and the pursuit of knowledge and self-improvement continue to resonate with scholars, artisans, and thinkers to this day.The legacy of Luban's life and work is woven into the very fabric of Chinese culture and civilization. His ingenious inventions, groundbreaking architectural designs, and profound philosophical insights have left an indelible mark on the collective consciousness of the Chinese people. Even centuries after his passing, Luban's name remains synonymous with innovation, creativity, and a deep reverence for the natural world.As I reflect on the remarkable story of Luban, I am struck by the timeless relevance of his achievements and theenduring impact of his legacy. In a world that continues to grapple with complex challenges, Luban's example serves as a powerful reminder of the transformative potential of human ingenuity, fueled by a steadfast dedication to problem-solving and a deep respect for the natural order.Through the lens of Luban's life and work, we are inspired to embrace the spirit of innovation, to seek solutions to the pressing issues of our time, and to strive for a harmonious coexistence between humanity and the natural world. His legacy, embodied in the tools, structures, and ideas that he so meticulously crafted, stands as a testament to the boundless potential of the human mind and the enduring power of creativity to shape the course of history.。
