雅思英語作文計算機和歷史
A. 英語作文：計算機的歷史（初一）
嘲笑別人，其實也是對自己的一種諷刺。而喜歡嘲笑別人的人，往往也都會一事無成。
在我身邊有著形形色色的人，但總有一些人會獨來獨往，他們是真的喜歡孤獨嗎？不見得。所以引起了我的好奇，在課余時間觀察了一下。
「呦，xx今天穿的裙子真丑啊。」，「你看看他可真笨，這么簡單的題都不會做。」之後會哈哈大笑。但這是不是源於自己內心的空虛？以為自己可以在嘲笑別人
的時候收貨快樂，到頭來只是讓自己在友誼的道路上越走越遠。那我們為什麼不能對嘲笑的心理說不呢？不要讓嘲笑他人的種子在我們的心理萌芽，其實這也是人生
旅途中的一種挑戰。
對嘲笑說不的同時，我會思考，我們為什麼會嘲笑別人，明明知道嘲笑是不對的可我們為什麼會繼續？其實這就是嘲笑別人的心理在作祟。因為嘲笑別人會使自己產
生一種優越感，即使你也不會這道題，即使你也不可能十全十美，但是嘲笑別人就會把你從自卑的泥潭中拔出，但卻將你推向了自負的潮水中。
讓我們對嘲笑說不，讓我們對自己狠一點。直視自己的不足，正視生活中的困難。對別人的優點要發自內心的贊美，對別人的不足我們要思考是否自己也會犯。
「人非聖賢，孰能無過」當別人犯錯時，不要嘲笑，要鼓勵，要寬容，更要給予支持和力量。當自己犯錯時，不要逃避，要正視，要解決，要虛心接納。
對嘲笑說不吧！那樣你就會感到生活充滿陽光和希望，你就會感到自己的可愛。

C. 雅思作文 計算機是否能取代老師
從我們生命的第一刻起，就已經開始譜寫自己的人生歷程，體驗著生活的五彩斑斕。我們的生活充滿了歡樂，我們用嘴唱出美妙的音符，用耳細聽歡聲笑語，在藍天下嬉戲打鬧，我們一直都是無比的辛福。但是又有誰察覺到我們身邊有一些殘疾人，他們生存在無際的黑暗裡。有的人因為沒有聽覺，而生活在無聲的世界裡，獨自一人承擔著這樣的痛苦;有的人因為無法說話，而無法表達自己的心聲，獨自一人度過艱辛的歲月;有的人因為身體殘缺，而一直看著別人在陽光下奔跑，獨自一人生存在破碎的世界。
很多人都認為殘疾人是沒用的、是廢物，沒有意義生存在世上，於是便去排斥他們。但是他們不知道殘疾人同樣也能像正常人一樣，他們也有生存在世上的理由。
我永遠也忘不了那天看到「心靈之聲」藝術團表演。他們雖然都是殘疾人，但他們不為自己而感到悲哀，他們堅強的活著，憑著驚人的意志力，讓自己對任何事情都抱有永不言敗的精神!看完「心靈之聲」藝術團帶來《千手觀音》。他們雖然聽不見任何聲音，但是也完美的表演了整場演出，他們身殘志不殘的精神讓我敬佩。
海倫•凱勒也說過：「世界上最美的事物，不一定能用眼睛看到或用手摸到，他們是必須用心靈去體會的。」的確是這樣，殘疾人雖然身體上出現了一點缺陷，但他們的生活也是豐富多彩的，他們的生活也有快樂。
還有在我們的殘奧會上，一名名運動員神采奕奕，精神抖擻。他們為我國贏得一塊又一塊的獎牌，為我國創下佳績。我們由衷的從心中向他們致敬，心中感到非常興奮。蘇嚇你然他們身體上有缺陷，但是他們化缺陷為優勢，我們應學習他們身上那種精神——堅持不懈，永不退縮，勇敢面對身體上的殘疾。
所以我們要做到為殘疾人做貢獻，不歧視他們，不排斥他們，從而使他們走出心中的陰影，回到「陽光」下，我相信，只要世上有真愛，世上會變的更美好。社會的愛，對於殘疾人來說就像疲倦的人得以依靠;就像迷路的人，找到一盞指路明燈;就像炎熱的人找到濃濃的綠蔭;就像心靈乾枯的人們找到一泓清澈山泉。
希望是人生之巔，生命的存在就有希望。讓我們關愛殘疾人、關注殘運會!
D. 求雅思英語作文
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.

F. 有關電腦的發展史,英文版
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.

計算機的發展史
公元前5世紀，中國人發明了算盤。它被廣泛應用於商業貿易，這是第一次的計算工具。 它也被認為是一台電腦的原型。直到17世紀，計算設備的第二個重要的一步。1666年，塞繆爾·莫蘭德是英國人，是加數和減數機的發明者。1832年，巴貝奇和約瑟夫·克萊門特發明了計算設備。它的大小幾乎一樣大的房子。1943年1月：在美國，開發了先進的計算機，它重達5噸，75萬件。這些電腦主要用於在戰爭開始。1987年：一個超級版本，它可以每秒運算200萬。目前，計算機的類型有很多朋友，根據計算機的處理速度分類，可分為五種類型：超級計算機、大型機、小型機、工作站和微型計算機。
「誰發明了計算機？」真正的答案是，許多發明家計算機的歷史貢獻。計算機的發展，反映了現代人類的智慧。
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.

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. (定語從句，賓語從句，非謂語，)
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. (表語從句，非謂語，比較句型，並列句，形式主語)
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. (形式主語，被動句，定語從句，條件狀語從句，非謂語，同位語從句，讓步狀語從句)
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. (非謂語，賓語從句，主語從句，被動句，條件狀語從句)
