A. 英语作文：计算机的历史（初一）
嘲笑别人，其实也是对自己的一种讽刺。而喜欢嘲笑别人的人，往往也都会一事无成。
在我身边有着形形色色的人，但总有一些人会独来独往，他们是真的喜欢孤独吗？不见得。所以引起了我的好奇，在课余时间观察了一下。
“呦，xx今天穿的裙子真丑啊。”，“你看看他可真笨，这么简单的题都不会做。”之后会哈哈大笑。但这是不是源于自己内心的空虚？以为自己可以在嘲笑别人
的时候收货快乐，到头来只是让自己在友谊的道路上越走越远。那我们为什么不能对嘲笑的心理说不呢？不要让嘲笑他人的种子在我们的心理萌芽，其实这也是人生
旅途中的一种挑战。
对嘲笑说不的同时，我会思考，我们为什么会嘲笑别人，明明知道嘲笑是不对的可我们为什么会继续？其实这就是嘲笑别人的心理在作祟。因为嘲笑别人会使自己产
生一种优越感，即使你也不会这道题，即使你也不可能十全十美，但是嘲笑别人就会把你从自卑的泥潭中拔出，但却将你推向了自负的潮水中。
让我们对嘲笑说不，让我们对自己狠一点。直视自己的不足，正视生活中的困难。对别人的优点要发自内心的赞美，对别人的不足我们要思考是否自己也会犯。
“人非圣贤，孰能无过”当别人犯错时，不要嘲笑，要鼓励，要宽容，更要给予支持和力量。当自己犯错时，不要逃避，要正视，要解决，要虚心接纳。
对嘲笑说不吧！那样你就会感到生活充满阳光和希望，你就会感到自己的可爱。

C. 雅思作文 计算机是否能取代老师
从我们生命的第一刻起，就已经开始谱写自己的人生历程，体验着生活的五彩斑斓。我们的生活充满了欢乐，我们用嘴唱出美妙的音符，用耳细听欢声笑语，在蓝天下嬉戏打闹，我们一直都是无比的辛福。但是又有谁察觉到我们身边有一些残疾人，他们生存在无际的黑暗里。有的人因为没有听觉，而生活在无声的世界里，独自一人承担着这样的痛苦;有的人因为无法说话，而无法表达自己的心声，独自一人度过艰辛的岁月;有的人因为身体残缺，而一直看着别人在阳光下奔跑，独自一人生存在破碎的世界。
很多人都认为残疾人是没用的、是废物，没有意义生存在世上，于是便去排斥他们。但是他们不知道残疾人同样也能像正常人一样，他们也有生存在世上的理由。
我永远也忘不了那天看到“心灵之声”艺术团表演。他们虽然都是残疾人，但他们不为自己而感到悲哀，他们坚强的活着，凭着惊人的意志力，让自己对任何事情都抱有永不言败的精神!看完“心灵之声”艺术团带来《千手观音》。他们虽然听不见任何声音，但是也完美的表演了整场演出，他们身残志不残的精神让我敬佩。
海伦•凯勒也说过：“世界上最美的事物，不一定能用眼睛看到或用手摸到，他们是必须用心灵去体会的。”的确是这样，残疾人虽然身体上出现了一点缺陷，但他们的生活也是丰富多彩的，他们的生活也有快乐。
还有在我们的残奥会上，一名名运动员神采奕奕，精神抖擞。他们为我国赢得一块又一块的奖牌，为我国创下佳绩。我们由衷的从心中向他们致敬，心中感到非常兴奋。苏吓你然他们身体上有缺陷，但是他们化缺陷为优势，我们应学习他们身上那种精神——坚持不懈，永不退缩，勇敢面对身体上的残疾。
所以我们要做到为残疾人做贡献，不歧视他们，不排斥他们，从而使他们走出心中的阴影，回到“阳光”下，我相信，只要世上有真爱，世上会变的更美好。社会的爱，对于残疾人来说就像疲倦的人得以依靠;就像迷路的人，找到一盏指路明灯;就像炎热的人找到浓浓的绿荫;就像心灵干枯的人们找到一泓清澈山泉。
希望是人生之巅，生命的存在就有希望。让我们关爱残疾人、关注残运会!

If you wanna talk about playground legends, the conversation begins right there. Demetrius "Hook" Mitchell is the legend. You can hear all the stories in the world, but you'll never believe it until you see it. He's done inhuman stuff, unreal stuff.
was by far the best player to come out of Oakland. Demetrius Hook Mitchell is the Bay's most notorious legend. Every cat with at least minimal knowledge of playground ball has a Hook Mitchell story. The tales of his leaping ability are common place. Jumping over cars, bikes and people wasn't no thing to Hook. Before his descent into narcotics hell, Hook was nothing but heavenly. If he'd just kept his head straight, he'd be in the league right now, dominating.
Unfortunately, Hook lives in a prison cell now and in other folks' memories.
Several NBA stars who also grew up in Oakland, including Gary Payton, Jason Kidd, Antonio Davis, Drew Gooden, and Brian Shaw, all of whom played with Mitchell on the streets, and were astonished by his skills, but were unable to help him avoid his sorry fate. They describe his unstable home life and the longing for community that drove him to the streets. Mitchell himself is shown playing prison league games, and is surprisingly still able to play above the rim.
His story, like others, was written on courts between the West and East Bay.

The oldest calculating tool is abacus that was invented by Chinese several thousand years ago. Since then human beings had tried to make a machine to calculate for many years. However, there had been no machine which can be called "computer" till 1946. In that year two Americans invented the first computer in the world. The volumn of the machine was so large that it took up a whole room, and its speed was very low. With the rapid development of IT, nowadays computers are much smaller and faster, and they have become one of essential tools for everybody.
MICROPROCESSOR AND MICROCOMPUTER
Microprocessor is a processor whose elements have been miniaturized into one or a few integrated circuits.It is a semiconctor central processing unit(CPU)and one of the principal components of the microcomputer.The elements of the microprocessor are frequently contained on a single chip or within the same package，but are sometimes distributed over several separate chips.[1] In a microcomputer with a fixed instruction set，the microprocessor consists of the arithmetic-logic unit and the control logic unit.In a microcomputer with a micro programmed instruction set，it contains an additional control-memory unit.[2]
Pentium And Power PC Evolution
In this section，we provide a brief overview of two computer families：the Intel Pentium and the IBM Power PC.The Pentium represents the results of decades of design effort on complex instruction set computers(CISCs).It incorporates the sophisticated design principles once found only on mainframes and supercomputers and serves as an excellent example of CISC design.The Power PC is a direct descendant of the first RISC system，the IBM 801，and is one of the most powerful and best-designed RISC-based systems on the market.[3]
1)The Pentium
One method of increasing the complexity of an integrated circuit is simply to scale the chip down.[4] For example，if every line etched into the silicon die could be shrunk in half，the same circuit could be built in one -fourth the area.The evolution of dynamic memory chips(DRAMs)follows this rule exactly.The original IBM PC used 16 KB DRAMs.These were soon replaced with 64 Kchips，then 256 KB chips，and now 16 MB，and even 64 MB chips…
The“trick”， course，is being able to improve processing skills sufficiently to allow this scaling to continue.In 1969，the minimum feature size(the smallest detail that can be etched into a chip)was 10 microns(10×10-6 meter).By 1997，this had shrunk to 0.25 micron—40 times smaller!
The Pentium uses a superscalar architecture.This means that the chip’s capabilities go beyond those achieved simply by scaling down its size.In particular，the Pentium is the first microprocessor in the Intel family to support two instruction pipelines，each with its own arithmetic-logic unit，address generation circuitry，and data cache interface.The result is a processor that can actually execute two different instructions simultaneously.
In 1965，Gordon Moore，one of the founders of Intel，was graphing chip complexity vs. time. He noticed that the number of integrated components doubled every two years.Moore then boldly predicted that this doubling would continue indefinitely.Remarkab1y，his prediction—now referred to as Moore’s law—has held up for more than 30 years.[5]
2)The Pentium MMX
In 1996，Intel began delivering versions of the Pentium with multimedia extensions (MMXs).These processors have three architectural enhancements over non-MMX processors(now renamed Pentium Classic).
For general applications，benchmark tests show a 10一20 percent improvement over the Pentium Classic，increasing to nearly 70 percent when multimedia-specific plications are considered.[6] Chips with(internal)click speeds as high as 233 MHz are available.
Applications of MMX processors include decompression of audio and video files.Indeed，software video players may become a reality.Some vendors are replacing conventional modems and sound cards with MMX-driven software equivalents.
3)The Pentium Pro
Perhaps the most striking feature of the Pentium Pro is the package itself.As shown in Fig. 2-1 the Pro consists of two separate silicon dies.The largest is the processor;fabricated with 0.35 micron design rules，it incorporates 5.5 million transistors.The smaller die beside it is a 256 KB level-two cache.Oddly enough，the cache has three times as many transistor，as the processor(16.5 millions)，but because of its uniformity，less silicon area is required.[7] Versions of the Pentium Pro with a 512KB，and a 1 MB cache are also available.
The Pentium Pro retains all of the architectural features of the Pentium that preceded it.That is，internally，all registers are 32 bits，while the external data bus is 64 bits wide.Four additional address lines have been added，allowing 64 GB of physical memory to be accessed.From a software point of view，the Pentium Pro remains 100% compatible with the previous generation of 80x86 processors.Three new processor instructions have been added，as well as two new floating-point-unit instructions.
The most touted feature of the Pentium Pro is what Intel calls dynamic execution.This new approach to processing software instructions that reces idle processor time to an absolute minimum.
4)The Pentium II
The newest member of the 80x86 family is the Pentium II.First made available in 1997，it is basically a Pentium Pro with MMX technology.
The Pentium II is made with 0.25-micron technology，allowing clock speeds of 300 MHz to 450 MHz.System bus frequencies as high as 100 MHz are suonorted.The lower clock speeds will support a 66 MHz system bus frequency.The level-two cache，which operates at half the speed of the processor，stores 512 KB and has its own 64-bit dedicated bus.The level-one cache has been increased from 16 KB in the Pentium Pro to 32 KB in the Pentium II.
5)Power PC
In 1975，the 801 minicomputer project at IBM pioneered many of the architecture concepts used in RISC systems.T801，together with the Berkeley RISC I processor，launched the RISC movement.The 801，however，was simply a prototype intended to demonstrate design concepts. The success of the 801 project led IBM to develop a commercial RISC workstation proct，the RT PC.The RT PC，introced in 1986，adapted the architectural concepts of the 801 to an actual proct.The RT PC was not a commercial success，and it had many rivals with comparable or better performance.In 1990，IBM proced a third system，which built on the lessons of the 801 and the RT PC.[8] The IBM RISC System /6000 was a RISC-like superscalar machine marketed as a high-performance workstation;shortly after its introction，IBM began to refer to this as the Power architecture.
For its next step，IBM entered into an alliance with Motorola，developer of the 68000 series of microprocessors，and Apple，which used the Motorola chip in its Macintosh computers.The result is a series of machines that implement the Power PC architecture. Changes were made to add key missing features and to enable more efficient implementation by eliminating some instructions and relaxing the specification to eliminate some troublesome special case.[9] The resulting Power PC architecture is a superscalar RISC system.
So far，four member of the Power PC family have been introced.

History of computer development
5th century BC, Chinese invented the abacus. It is widely used in commercial trade, and this is the first calculation tool. It’s also considered the prototype of a computer. Until the 17th century, computing devices have a second important step forward. In 1666, Samuel Morland who was English ，invented the addend and subtrahend machine.
1832, Babbage and Joseph Clement made a computing device. It’s Size nearly as big a house. January 1943: In the United States, An advanced computer was developed which weighs 5 tons, 75 million parts. These computers are mainly used in the war began.1987: A supercomputer release, which can made 200 million operations per second. At present, the type of computer has a lot of friends, according to the computer’s processing speed classification, It can be divided into five types：supercomputers,mainframes,minicomputers,workstations and microcomputers
"Who invented the computer?” The real answer is that many inventors contributed to the history of computers. The development of computers reflects the wisdom of modern humans.

计算机的发展史
公元前5世纪，中国人发明了算盘。它被广泛应用于商业贸易，这是第一次的计算工具。 它也被认为是一台电脑的原型。直到17世纪，计算设备的第二个重要的一步。1666年，塞缪尔·莫兰德是英国人，是加数和减数机的发明者。1832年，巴贝奇和约瑟夫·克莱门特发明了计算设备。它的大小几乎一样大的房子。1943年1月：在美国，开发了先进的计算机，它重达5吨，75万件。这些电脑主要用于在战争开始。1987年：一个超级版本，它可以每秒运算200万。目前，计算机的类型有很多朋友，根据计算机的处理速度分类，可分为五种类型：超级计算机、大型机、小型机、工作站和微型计算机。
“谁发明了计算机？”真正的答案是，许多发明家计算机的历史贡献。计算机的发展，反映了现代人类的智慧。
Evolution of the Computer:
The first counting device was the abacus, originally from Asia. It worked on a place-value notion meaning that the place of a bead or rock on the apparatus determined how much it was worth.
1600s: John Napier discovers logarithms. Robert Bissaker invents the slide rule which will remain in popular use until 19??.
1642: Blaise Pascal, a French mathematician and philosopher, invents the first mechanical digital calculator using gears, called the Pascaline. Although this machine could perform addition and subtraction on whole numbers, it was too expensive and only Pascal himself could repare it.
1804: Joseph Marie Jacquard used punch cards to automate a weaving loom.
1812: Charles P. Babbage, the "father of the computer", discovered that many long calculations involved many similar, repeated operations. Therefore, he designed a machine, the difference engine which would be steam-powered, fully automatic and commanded by a fixed instruction program. In 1833, Babbage quit working on this machine to concentrate on the analytical engine.
1840s: Augusta Ada. "The first programmer" suggested that a binary system shouled be used for staorage rather than a decimal system.
1850s: George Boole developed Boolean logic which would later be used in the design of computer circuitry.
1890: Dr. Herman Hollerith introced the first electromechanical, punched-card data-processing machine which was used to compile information for the 1890 U.S. census. Hollerith's tabulator became so successful that he started his own business to market it. His company would eventually become International Business Machines (IBM).
1906: The vacuum tube is invented by American physicist Lee De Forest.
1939: Dr. John V. Atanasoff and his assistant Clifford Berry build the first electronic digital computer. Their machine, the Atanasoff-Berry-Computer (ABC) provided the foundation for the advances in electronic digital computers.
1941, Konrad Zuse (recently deceased in January of 1996), from Germany, introced the first programmable computer designed to solve complex engineering equations. This machine, called the Z3, was also the first to work on the binary system instead of the decimal system.
1943: British mathematician Alan Turing developped a hypothetical device, the Turing machine which would be designed to perform logical operation and could read and write. It would presage programmable computers. He also used vacuum technology to build British Colossus, a machine used to counteract the German code scrambling device, Enigma.
1944: Howard Aiken, in collaboration with engineers from IBM, constructed a large automatic digital sequence-controlled computer called the Harvard Mark I. This computer could handle all four arithmetic opreations, and had special built-in programs for logarithms and trigonometric functions.
1945: Dr. John von Neumann presented a paper outlining the stored-program concept.
1947: The giant ENIAC (Electrical Numerical Integrator and Calculator) machine was developped by John W. Mauchly and J. Presper Eckert, Jr. at the University of Pennsylvania. It used 18, 000 vacuums, punch-card input, weighed thirty tons and occupied a thirty-by-fifty-foot space. It wasn't programmable but was proctive from 1946 to 1955 and was used to compute artillery firing tables. That same year, the transistor was invented by William Shockley, John Bardeen and Walter Brattain of Bell Labs. It would rid computers of vacuum tubes and radios.
1949: Maurice V. Wilkes built the EDSAC (Electronic Delay Storage Automatic Computer), the first stored-program computer. EDVAC (Electronic Discrete Variable Automatic Computer), the second stored-program computer was built by Mauchly, Eckert, and von Neumann. An Wang developped magnetic-core memory which Jay Forrester would reorganize to be more efficient.
1950: Turing built the ACE, considered by some to be the first programmable digital computer.

H. 雅思大作文范文：电脑比人类更智能会有哪些利弊影响
6.5分：
智能计算机的好处1：智能计算机能够解放人力，在各个行业工作。
智能计算机的好处2：智能计算机能够提高效率。
智能计算机的坏处1：人工智能机器的广泛应用会降低就业率，导致贫富差距加大。
智能计算机的坏处2：人类对机器会更加依赖，失去基本的生存技能或者生活经验。
智能计算机的坏处3：智能机器人会带来道德问题。
Computer technology is advancing dramatically since its invention and has shown some possibility of intelligence, which means (that) they are capable to think, and therefore make judgment and initiate action in complex situation, featuring like human brains. This excites many people while arousing some concern about its hidden hazard to human being. (定语从句，宾语从句，非谓语，)
Of course those optimists have their own reasons. The first one is that intelligent computers would free human labor to an enormous extent. They would replace human workers in many walks of life, performing many tasks in medical procere, manufacture, domestic service, space and ocean exploration and so on. They can work more efficiently, accurately than human counterparts and they never feel tired or fear any danger. It is claimed that these advantages would increase the proctivity of the whole world for long run and bring human comfort and convenience. (表语从句，非谓语，比较句型，并列句，形式主语)
However it also makes sense to worry about the potential risk that computational intelligence may impose on human race. It is generally believed that employment rate would decline if artificial intelligent machines are widely applied to substitute for human labors. Correspondingly, the wealth gap can be inferred wider. In addition to economic impact, human community may increase dependence on smart technology, losing some basic living skills or life experience. Some pessimists show their concern about ethical issue in literature involving robots which are likely to manipulate humans. Nonetheless, many people hold the belief that no matter how intelligent a computer is, it is programed by human being and is under human’s control for sure. (形式主语，被动句，定语从句，条件状语从句，非谓语，同位语从句，让步状语从句)
Based on the discussion above, I personally think that whether advanced technology can benefit human race or not is determined by how we human utilize it. Technology is supposed to be neutral and has no threat on human designers. If we put it to good use, then we would make the most of technology. (非谓语，宾语从句，主语从句，被动句，条件状语从句)
