SCIENTIFIC① BREAKTHROUGHS
If you had to choose the single most important discovery of the 20th century,you would have a real problem on your hands. [1] In just 100 years,the world has changed completely. Amazing discoveries were made in medicine,communications and transport,not to mention② our knowledge of the world and space. Medical advances ranged from discovering the causes of diseases under microscopes④ to③ staging operations to replace diseased organs with donated⑤ ones. Communications changed with the introduction of⑥ mobile phones,and the way we correspond⑦ went from writing letters to emailing and sending instant⑧ messages. We started flying around the world,launching⑨ satellites⑩ into orbit⑪ and,at the same time,scientists figured out how to split⑫ the atom,previously thought to be the smallest particle⑬ of matter in the universe[2].
[1]此处If引导虚拟条件状语从句,意为“如果”。
[2]此处含有“疑问词+to do sth”的结构,在句中作宾语;动词-ed形式短语作后置定语,修饰the atom。
学生用书第94页
Although it is impossible to choose the most important discovery,it is possible to single out⑭ a few pioneers of the 20th century. Here are some of them.
One of the 20th century’s premier⑮ scientists was Albert Einstein. In the summer of 1905,this outspoken⑯ young man was rocking his one-year-old baby when[3] he was suddenly inspired. Subsequently⑰,“E=mc2” was born. It showed how a small piece of mass could produce an unbelievable amount of energy[4]. Einstein then showed in his “theory of relativity⑱” that not even time,mass or length are constant⑲—they change according to our experience of them.
[3]此处be doing sth when… 是固定句式,意为“正在做某事,这时(突然)……”。
[4]此处how引导宾语从句,作showed的宾语。
In 1928,another important finding⑳ was made by biologist㉑ Alexander Fleming. Before he went on holiday,Fleming left a dish of bacteria in his laboratory. When he came back,he noticed something strange. He double-checked㉒ and saw a blue mould㉓ in the dish around which the bacteria had been destroyed[5]. This blue mould was in fact the natural form of penicillin㉔,which Fleming perceived㉕ could be used to kill bacteria[6]. A few years later,penicillin was being mass-produced㉖ and helping to save the lives of millions㉗. Fleming remained humble㉘ about the amazing outcome㉙ of his discovery. “Nature made penicillin,”he said,“I just found it. ”
[5]around which引导定语从句,修饰先行词 dish。
[6]which引导非限制性定语从句。which指代penicillin,作从句的主语。
During World War Ⅱ,when Fleming’s discovery was first helping to cure people,the US Navy㉚ was looking for ways of improving the accuracy㉛ of their missiles㉜. The navy turned to㉝ Eckert,an engineer,and Mauchly,a physicist㉞,to deal with㉟ the problem and produce a machine to do the job in a joint㊱ effort. Although they only finished after the war in 1946,it did not matter. This huge machine was the world’s first computer,but it was nothing like㊲ our computers today. It measured 100 feet long by over 10 feet high and weighed over 30,000 kilograms. With 18,000 tubes㊳,thousands of circuits㊴ and 6,000 switches,it used so much energy that when it was turned on,the lights in the local town went out㊵![7]
学生用书第95页
[7]so… that… “如此……以至于……”,引导结果状语从句。该结果状语从句中又包含了一个when引导的时间状语从句。
With the development of computers,people expected to get more things done[8]efficiently㊶. During the Cold War,a “huge network” of computers was proposed㊷ by two American scientists. With computers talking to one another[9],it would enable government leaders to communicate with each other. By the end of the 1960s,some mini-networks were established,but only a few computers could connect to them. In 1990,Tim Berners-Lee invented the World Wide Web,which enabled computers all over the world to communicate with each other. Nowadays,life without the Internet for most people is unimaginable㊸.
[8]get more things done为“get sth done”结构,意为“使某事被做”。
[9]此处为with复合结构,其中动词-ing形式短语作补语,补充说明computers的内容。
These pioneers of the 20th century were all dedicated to㊹ improving the quality㊺ of human life on Earth. Human life on this planet has been transformed into a “global village”,with all the different countries linked in the chain of㊻ common interests. There is no doubt about[10] it. Without the breakthroughs of these pioneers in science and technology,whether lucky or planned[11],the world as we know it today would be a completely different place.
[10]There is no doubt about/that… “毫无疑问……”
[11]“whether lucky or planned”是一个省略句,补全为whether it was lucky or it was planned。

科学突破
如果必须在20世纪重大发现中选出最重要的一项,这可不是件容易的事。在仅仅100年中,世界就完全变样了。医学、通信和交通方面都有惊人的发现,更别提我们对世界和太空的认识了。医学上的进步范围很广,从利用显微镜揭示病因,到施行手术,用捐赠的器官做器官移植。移动电话的使用给通信业带来了改变,通信方式从写信到发电子邮件和发送即时信息。我们开始坐飞机周游世界,把人造卫星发射至轨道。同时,科学家们发现了如何分裂原子。在此之前,原子被认为是宇宙中最小的物质微粒。
尽管不太可能选出哪项发现是最重要的,但是挑选出20世纪的几位先驱还是可能的。例如以下几位:
20世纪最杰出的科学家,爱因斯坦是其中之一。1905年夏天,这个坦率的年轻人给他一岁的孩子晃动摇篮时,这时他突然受到启发。于是,“E=mc2”诞生了。它证明了一小块物质可以产生巨大的能量。爱因斯坦随后在他的“相对论”中指出,即使是时间、质量或长度也不是恒定不变的,它们根据我们对它们的感知而变化。
1928年,另一项重要的发现由生物学家亚历山大·弗莱明发现的。在去度假之前,弗莱明在实验室里放了一个培养细菌的器皿。回来时,他注意到器皿里有点儿奇怪。经过反复检查,他发现器皿里有一种蓝色的霉菌,而霉菌周围的细菌已经被杀死了。这种蓝色的霉菌实际上是自然状态的青霉素,弗莱明认为它可以用来杀死细菌。数年后,青霉素开始大量生产,帮助挽救了数百万人的生命。弗莱明对他这一惊人的发现态度谦虚,他说:“是大自然制造了青霉素,我只是发现了它。”
第二次世界大战期间,正当弗莱明的发现首次用来帮助治愈人们时,美国海军正在寻找提高导弹精度的方法。海军求助于工程师埃克特和物理学家莫克利来处理这个问题,两人共同努力制造一台机器来完成这项工作。尽管他们直到1946年战争结束后才完成,但这并不重要。这台巨大的机器是世界上第一台计算机,但是与今天的计算机完全不同。它长100英尺,高10英尺,重30 000多公斤。它有18 000个显像管,数千条电路和6 000个开关,耗电量异常巨大,以致于当它启动的时候,当地所有的灯都熄灭了!
随着计算机的发展,人们期望能有效地完成更多的事情。冷战期间,两位美国科学家提出建立一个计算机的“庞大网络”。计算机能互换信息,可使政府领导人相互沟通。到20世纪60年代末,一些小型网络已经被建立起来了,但只有少数计算机可以接入。1990年,蒂姆·博纳·李发明了万维网,使世界各地的计算机能够相互通信。如今,对大多数人来说,没有互联网的生活是难以想象的。
这些20世纪的先驱都致力于改善地球上人类的生活质量。不同国家在共同利益链中相互联系,使得这个星球上人类的生活已经转变为“地球村”。毫无疑问,如果没有这些先驱取得的科技突破,无论这些突破是偶然发现的还是计划之中的,我们今天所熟知的世界将是一个完全不同的地方。
