Lesson 51 Predicting the future
1 . In 1975, a primitive machine called the Altair, was launched in the USA.1975年，美國推出了一台被稱為「牛郎星」的原始機型。
2 . If he, or someone like him, were alive today, he might be able to tell us what to expect in the next fifty years.如果他或是像他的什麼人今天還活著的話，他大概可以告訴我們下一個50年後會發生什麼事情。
3 . when they would be capable of providing information about traffic jams and suggesting alternative routes, when they would be used in hospitals to help doctors to diagnose illnesses, when they would relieve office workers and accountants of dull, repetitiv計算機可以使辦公室人員和會計免除那些枯燥、重複的勞動。
4 . Bagrit foresaw a time when computers would be small enough to hold in the hand,巴格瑞特預示有一天計算機可以小到拿在手上，
5 . The IBM Personal Computer was widely copied.IBM的個人電腦被大規模地模仿。
6 . Nor could he have foreseen how we could use the Internet to obtain information on every known subject, so we can read it on a screen in our homes and even print it as well if we want to.他也無法預測到我們可以利用國際交互網獲取有關任何已知專題的信息，以便在家裡的屏幕上閱讀，如果願意的話甚至可以將其打印出來。
7 . It can properly be described as the first 'home computer' and it pointed the way to the future.嚴格地說起來，它可以被稱為第一台「家用電腦」，而且它也指了今後的方向。
8 . Predicting the future is notoriously difficult.眾所周知，預測未來是非常困難的。
9 . These were the so-called mainframe machines.它們被稱為主機。
10 . Considering how recent these developments are, it is even more remarkable that as long ago as the 1960s, an Englishman, Leon Bagrit, was able to predict some of the uses of computers which we know today.想一想這些發展的時間多麼短，就更覺得英國人萊昂。巴格瑞特有著非凡的能力。他在60年代就能預言我們今天知道的計算機的一些用途。
11 . Though these large machines still exist, many of their functions have been taken over by small powerful personal computers, commonly known as PCs.雖然這種大計算機仍然存在，但它們的許多功能已被體積小但功能齊全的個人電腦——即我們常說的PC機——所代替了。
12 . This is what makes Leon Bagrit's predictions particularly remarkable.這就是萊昂。巴格瑞特的預測非凡的地方。
13 . Mainframe computers were very large indeed, often occupying whole air-conditioned rooms,計算機主機確實很大，常常佔據了裝有空調的多間房間，
14 . employing full-time technicians and run on specially-written software.僱用專職的技師，而且得用專門編寫的軟件才能運行。
15 . This ran on an 'operating system' called DOS, produced by a then small company named Microsoft.這種電腦採用了一種被稱為磁盤操作系統（DOS）的工作程序，而這種程序是由當時規模不大的微軟公司生產的。
16 . Of course, Leon Bagrit could not possibly have foreseen the development of the Internet, the worldwide system that enables us to communicate instantly with anyone in any part of the world by using computers linked to telephone networks.當然了，萊昂。巴格瑞特根本沒有可能預測到國際交互網——就是把計算機連結到電話線路上，以便和世界上任何一個地方的人立即進行聯繫的一個世界範圍的通訊系統——的發展。
17 . Who could have imagined, in the mid 1970s, for example, that by the end of the 20th century, computers would be as common in people's homes as TV sets?舉個例子吧，在20世紀70年代中葉又有誰能想得到在20世紀末的時候，家庭用的計算機會像電視機一樣普遍？
18 . In the 1970s, computers were common enough, but only in big business, government departments, and large organizations.在70年代，計算機已經相當普及了，但只用在大公司，政府部門和大的組織之中，
19 . This was followed, at the end of the 1970s, by a machine called an Apple.70年代末，在牛郎星之後又出現了一種被稱為「蘋果」的機型。
20 . Bagrit dismissed the idea that computers would learn to 'think' for themselves and would 'rule the world', which people liked to believe in those days.巴格瑞特根本不接受計算機可以學會自己去「思考」和計算可以「統治世界」這種想法，而這種想法是當時的人們都願意相信的。
21 . In the early 1980s, the computer giant, IBM produced the world's first Personal Computer.80年代初，計算機行業的王牌公司美國國際商用機器公司（IBM）生產出了世界上第一台個人電腦。
22 . From those humble beginnings, we have seen the development of the user-friendly home computers and multimedia machines which are in common use today.從那些簡陋的初級階段，我們看到了現在都已普及的、使用簡便的家用電腦和多媒體的微機的發展。
23 . All these computer uses have become commonplace.計算機的所有這些功能現在都變得很平常。
24 . Computers have become smaller and smaller, more and more powerful and cheaper and cheaper.計算機已經變得體積越來越小，功能越來越多，價格越來越低，
