The Computer Chronicles
by Roderick Hames
In the beginning ...
A generation refers to the state of improvement in the development of a product. This term is also used in the different advancements of computer technology. With each new generation, the circuitry has gotten smaller and more advanced than the previous generation before it. As a result of the miniaturization, speed, power, and memory of computers has proportionally increased. New discoveries are constantly being developed that affect the way we live, work and play.
The First Generation: 1946-1958 (The Vacuum Tube Years)
The first generation computers were huge, slow, expensive, and often undependable. In 1946two Americans, Presper Eckert, and John Mauchly built the ENIAC electronic computer which used vacuum tubes instead of the mechanical switches of the Mark I. The ENIAC used thousands of vacuum tubes, which took up a lot of space and gave off a great deal of heat just like light bulbs do. The ENIAC led to other vacuum tube type computers like the EDVAC (Electronic Discrete Variable Automatic Computer) and the UNIVAC I (UNIVersal Automatic Computer).
The vacuum tube was an extremely important step in the advancement of computers. Vacuum tubes were invented the same time the light bulb was invented by Thomas Edison and worked very similar to light bulbs. It's purpose was to act like an amplifier and a switch. Without any moving parts, vacuum tubes could take very weak signals and make the signal stronger (amplify it). Vacuum tubes could also stop and start the flow of electricity instantly (switch). These two properties made the ENIAC computer possible.
The ENIAC gave off so much heat that they had to be cooled by gigantic air conditioners. However even with these huge coolers, vacuum tubes still overheated regularly. It was time for something new.
The Second Generation: 1959-1964 (The Era of the Transistor)
The transistor computer did not last as long as the vacuum tube computer lasted, but it was no less important in the advancement of computer technology. In 1947 three scientists, John Bardeen, William Shockley, and Walter Brattain working at AT&T's Bell Labs invented what would replace the vacuum tube forever. This invention was the transistor which functions like a vacuum tube in that it can be used to relay and switch electronic signals.
There were obvious differences between the transisitor and the vacuum tube. The transistor was faster, more reliable, smaller, and much cheaper to build than a vacuum tube. One transistor replaced the equivalent of 40 vacuum tubes. These transistors were made of solid material, some of which is silicon, an abundant element (second only to oxygen) found in beach sand and glass. Therefore they were very cheap to produce. Transistors were found to conduct electricity faster and better than vacuum tubes. They were also much smaller and gave off virtually no heat compared to vacuum tubes. Their use marked a new beginning for the computer. Without this invention, space travel in the 1960's would not have been possible. However, a new invention would even further advance our ability to use computers.
The Third Generation: 1965-1970 (Integrated Circuits - Miniaturizing the Computer)
Transistors were a tremendous breakthrough in advancing the computer. However no one could predict that thousands even now millions of transistors (circuits) could be compacted in such a small space. The integrated circuit, or as it is sometimes referred to as semiconductor chip, packs a huge number of transistors onto a single wafer of silicon. Robert Noyce of Fairchild Corporation and Jack Kilby of Texas Instruments independently discovered the amazing attributes of integrated circuits. Placing such large numbers of transistors on a single chip vastly increased the power of a single computer and lowered its cost considerably.
Since the invention of integrated circuits, the number of transistors that can be placed on a single chip has doubled every two years, shrinking both the size and cost of computers even further and further enhancing its power. Most electronic devices today use some form of integrated circuits placed on printed circuit boards-- thin pieces of bakelite or fiberglass that have electrical connections etched onto them -- sometimes called a mother board.

These third generation computers could carry out instructions in billionths of a second. The size of these machines dropped to the size of small file cabinets. Yet, the single biggest advancement in the computer era was yet to be discovered.
The Fourth Generation: 1971-Today (The Microprocessor)
This generation can be characterized by both the jump to monolithic integrated circuits(millions of transistors put onto one integrated circuit chip) and the invention of the microprocessor (a single chip that could do all the processing of a full-scale computer). By putting millions of transistors onto one single chip more calculation and faster speeds could be reached by computers. Because electricity travels about a foot in a billionth of a second, the smaller the distance the greater the speed of computers.
However what really triggered the tremendous growth of computers and its significant impact on our lives is the invention of the microprocessor. Ted Hoff, employed by Intel (Robert Noyce's new company) invented a chip the size of a pencil eraser that could do all the computing and logic work of a computer. The microprocessor was made to be used in calculators, not computers. It led, however, to the invention of personal computers, or microcomputers.
It wasn't until the 1970's that people began buying computer for personal use. One of the earliest personal computers was the Altair 8800 computer kit. In 1975 you could purchase this kit and put it together to make your own personal computer. In 1977 the Apple II was sold to the public and in 1981 IBM entered the PC (personal computer) market.
Today we have all heard of Intel and its Pentium® Processors and now we know how it all got started. The computers of the next generation will have millions upon millions of transistors on one chip and will perform over a billion calculations in a single second. There is no end in sight for the computer movement.

问对人了,在下大学英语翻译专业的,这个问题是这样的：
因为 and 如果连接两个句子的话,这两个句子必须是完整的,有主谓宾成分的句子.这个句子是正确的,因为这里是一个主语的两个并列谓语,用also是可以的.如果要用and 的话应该是这样：1,Musician Bill influenced generations of artists,and he （also） inspired many musicians.必须添上he 作主语,因为这里and 连接的是两个完整的句子,为并列句.或者2,Musician Bill influenced generations of artists and inspired many musicians.此时不加逗号,and连接的是两个并列动词,一起作谓语.

一代又一代的美国人已经带来的相信美好的早餐是一个生活的必需品.吃早餐的开始的一天,我们都被告知,告诉了,当必要把汽油的家庭汽车开始前的一次旅行.
但是对于很多人来说思想的食物早上的第一件事决不是一种乐趣.尽管所有的力量,他们还带不吃早餐.1977年,1983年之间的最近一年数据,多少人没吃早餐,增加了33%.
对那些觉得痛苦不吃早餐的内疚,但有一些好消息.有几项研究在过去的几年里表明,为成人特别是,可能会有一点问题都没有省略早餐.不吃早餐的情况下不影响性能的Arrold说,“e酒会、前教授英国女王伊丽莎白二世营养学院在伦敦,”也没有给人早餐更好的表现.”
科学的证据来连结的早餐更好的健康或更好的表现令人惊奇的不足,而且大部份的最近的工作包括小孩,而不是在成人,”文学,他说:“Erresto(不知道)患病的一名研究人员,在德州大学,“贫”.

Recently,as students we spend less and less time on the communication with our parents.We only pay attention to the Internet,we only chat online with our friends or classmates or even with strangers.
Meanwhile,as parents,they can't understand what their children .They can't keep the pace with the trend.So they have no chance to talk with eath other and they have no commom language.
见解一般,请见谅哈

在世代之间,非常被采取假定没有评论对此任何长期,是更低和中产阶级状态,孩子开始渐渐离开当他们是足够老的去学校.

这是音标划分问题.
我们以它的美式发音[dʒenə'reɪʃnz]为例分析
音标是靠元音来把自己分为一个个音节,一般一个元音和左边最靠近自己的辅音组成一个音节,看上面的例子
第一个短元音e与左边的dʒ组成一个音节,在单词里面体现为ge.同样的第二个音节为nə'体现为ne,第三个为reɪ体现为ra,由于其后面没有元音了,所以ʃn（体现为tion）和z（s）各自成为第四第五个音节

如果怀疑掠过他们的心头,已经被这么告诉的孩子的世代在被诅咒的恐惧中成长…

C
首先,B和D都是被动语态,排除.
其次,“他们家世代居住”发生在“房子被拆除给高速公路留下空间”之前,过去的过去,要用过去完成时态.

一个大的转变是,与前几代人相比,幽默,而不是音乐,是他们自我表现的第一形式.

几十年来,我们一直在喂养幼儿,帮助他们快乐地成长.我们知道2-3岁之间,你的孩子仍然具有特定的营养需求,事实上专家提醒,在幼儿可以爬的这个年龄段,他们的主要饮料是半脱脂牛奶.然而,即使这提供了所有善良的,它仍然是并不总是容易满足他们所有的营养需求,因为有一天,他们需要比别人吃的更好.
我们已经开发供年龄2-3岁幼儿吃的牛奶,牛栏牌成长特别牛奶,半脱脂的版本,提供牛奶的精华,但也包含基本幼儿营养,所以你可以确保你的孩子,满足他们每天需要的维生素和矿物质.

它们(电脑)被认为,像人一样,也按“代”来划分,(而且)代与代之间的间距越来越小.
in terms of
就…而言,从…方面说,按.分.
generation:代,同时代的人,一代人,
都是一样的意思,都是"代"

1. all together是一共的意思,不是一起.
2.over用作介词有支配的意思,符合题意,其他的没有此意思.
3.都表示几乎没有的意思,few用于可数名词前,little用在不可数名词前.
4.could的语气比can要委婉些,在这句话都可以看成是委婉的建议.

从过去,以未来后代之名 – 满足创新,为人类提供技术服务 – 我们和我们数十亿用户以及追随者与时俱进.

没必要,这个situation是泛指,理解为这个现象到处都是就好了

这句话本身有问题 the world over 它的本意思遍布世界的,修饰 younger generations ,可是写错了,Inparticular, 也是,应该是particularly,后边的句子都没问题.
尤其是,世界各地的能支付得起使用像有线电视和互联网的年轻一代,经常遇到相同的媒体,比如广告,电影,电视频道,大众商标等等.
younger generations 主语the world over 地点状语who can afford access to media technologies like cable television and the Internet 定语从句修饰younger generations,真正的谓宾是often encounter the same media such as advertisements, films, TV channels, popular brands and so on.
正式的刊物尤其是科学报道语法结构上一般不会出错,像小说和非正式刊物只要大致能理解其意就好
