4、coveries were made in medicine, communications and transport, not to mention our knowledge of the world and space. Medical advances ranged from discovering the causes of diseases under microscopes(显微镜) to surgical procedures replacing diseased organs (器官)with donated (捐赠)ones. Communications changed
5、 with the introduction of mobile phones and the way we correspond went from writing letters to emailing. We started flying around the world and meanwhile, scientists figured out how to split(分离) the atom, previously thought to be the smallest particle of matter in the universe.Although it is impossi
6、ble to choose the most important discovery, it is possible to single out a few pioneers of the 20th century. Here are five of them.科学先锋如果你要选出20世纪个人最为重要的发现，你就会面临一个真正的难题。在仅仅100年的时间里，世界完全发生了变化。人们在医药、通信和运输方面做出了令人惊叹的发现，更不要说我们对世界和太空的知识发现了。人们在显微镜下看到了致病的原因，掌握了用捐献的器官来替换染病器官的外科手术程序，诸如此类都是医学取得的进步。通迅随着移动电话的引入而改
7、变，我们的通信方式从写信变成了发电子邮件。我们开始在世界各地飞行，与此同时，科学家们发现了怎样分离原子，而原子以前被认为是宇宙中最小的物质微粒。虽然要选出最为重要发现是不可能的，然而却有可能选出20世纪的一些科学先锋。以下是他们中的五个代表。助读讲解range from.to.从到不等。we correspond是定语从句修饰先行词the way，the way在从句中作状语。过去分词短语作定语修饰the atom。One of the 20th centurys premier(最主要的) scientists was Albert Einstein. In the summer of 19
8、05, this outspoken young man was rocking his oneyearold baby when he was suddenly inspired. “Emc2” was born. Emc2 showed how a small piece of mass could produce an unbelievable amount of energy. Einstein then showed in his “theory of relativity” that not even time, mass or length are constantthey ch
9、ange according to our experience of them.Einstein had already become worldfamous when a young exlawyer，returning from the First World War， started work in California.Using the most highpowered telescope(望远镜) of the time， he began the long, slow process of exploring our galaxy(星系)Edwin Hubble was abo
10、ut to make astronomys greatest breakthrough of the century.He discovered small areas of mist(薄雾)which were in fact galaxies like our own, millions of light years away from us, which proved that the universe was vastly larger than had previously been thought.20世纪最为著名的科学家之一是阿尔伯特爱因斯坦。1905年夏天，这位直率的年轻人正在
11、摇着他一岁的孩子时，突然产生了灵感，“Emc2”Emc2表明质量很小的物质是如何产生了令人难以置信的能量的。爱因斯坦后来在他的“相对论”里表明，时间、质量或者长度甚至都不是恒定不变的他们随我们的经历而发生改变。从一战中转战回来，曾经担任过律师的年轻人在加利福尼亚开始工作时，爱因斯坦已经举世闻名了。这位年轻人用当时功率最大的望远镜开始了对我们银河系长期而缓慢的探索过程。埃德温哈勃即将要做出那个世纪最伟大的发现了。他发现了一些小的雾区，而这些小雾区实际上是跟我们的星系一样的星系，它们离我们有几百万光年之远，这一发现表明宇宙比我们以前想象的要大得多。助读讲解be doing sth.when.表示“
12、正在做某事，这时”。returning from.是现在分词作后置定语。Using the most.是现在分词短语作方式状语。which were in fact galaxies like our own是定语从句修饰先行词small areas of mist；which proved that.是定语从句，修饰he discovered small areas of mist；that the universe was vastly larger.是that引导的宾语从句。In 1929, another farreaching finding was made by the son
13、of a Scottish shepherd. Before he went on holiday, biologist Alexander Fleming left a dish with bacteria (细菌)in it in his laboratory. When he came back, he noticed something strange. He doublechecked and saw a blue mould (霉菌)in the dish around which the bacteria had been destroyed. This blue mould w
14、as in fact the natural form of penicillin, which Fleming realised could be used to kill bacteria.A few years later, penicillin was being massproduced and helping to save the lives of millions. Fleming remained modest about the amazing outcome of his discovery. “Nature made penicillin，” he said, “I j
15、ust found it.”During the Second World War，when Flemings discovery was first helping to cure people, the US Navy was looking for ways of improving the accuracy (精确度)of their missiles. The navy turned to Eckert, an engineer, and Mauchly, a physicist， to wrestle with the problem and produce a machine t
16、o do the job. Although they only finished after the war in 1946, it did not matter. This huge machine was the worlds first computer, but it was nothing like our computers today. It measured 100 feet long by over 10 feet high and weighed over 30 tonnes. With 18，000 tubes, thousands of circuits and 6，
17、000 switches, it used so much energy that when it was turned on, the lights in the local town went out！1929年，一位苏格兰牧羊人的儿子做出了另外一项影响深远的发现。生物学家亚历山大弗莱明在度假前将一个里面有细菌的碟子丢在实验室里。当他度假回来，看到一些奇怪的东西。他做进一步的核查，看到了碟子里有一种蓝色的霉，其周围的细菌都被消灭了。这些蓝色的霉实际上就是自然状态下的青霉素，弗莱明意识到可以用它来杀死细菌。几年以后，青霉素就被大批量生产，帮助挽救了几百万人的生命。对他的发现所产生的惊人的效果
18、，弗莱明仍持谦虚的态度。他说：“是大自然创造了青霉素，而我只是发现了他。”二战期间，当弗莱明的发明首先用来为人们治病时，这时美国海军正在寻找能提高导弹精确度的方法。海军方面向工程师埃克特和物理学家莫克利求助，希望他们能解决这个问题，并制造一台能完成这份工作的机器。虽然他们的工作是在1946年战后才完成，不过这并没有什么关系。这台巨大的机器就是世界上的第一台计算机，不过他一点也不像我们今天的计算机。它有100英尺长，10多英尺高，并且重达30多吨，装有18 000根管子，几千条电路和6 000个开关，它的耗电量是如此之大，以至于他一开机，当地镇上的电灯就熄灭了。助读讲解本句是“介词关系代词”引导
19、的定语从句。which引导非限定性定语从句，修饰penicillin。an engineer和a physicist分别作Eckert和Mauchly的同位语。so.that.“如此以至于”，引导结果状语从句。These pioneers of the 20th century were all dedicated (专心致志的)to improving the quality of human life on earth, but sometimes breakthrough discoveries that have affected our lives today happened by
20、 mistake! For example, we are all grateful for the handy microwave (微波炉)oven that allows us to prepare meals in minutes and we have Percy Spencer to thank. This inventor, with 120 patents (专利)to his name, discovered microwaves when he was experimenting with radars and noticed a chocolate melting in
21、his pocket.There is no doubt about it. Without the breakthroughs of these pioneers in science and technology, whether lucky or planned, the world as we know it today would have been a completely different place.这些20世纪的先锋们都致力于提高我们地球人类的生活质量，但至今有时候仍在影响着我们的突破性的发现却是在出错的情况下发生的。例如，微波炉让我们在几分钟内就能把饭准备好，对于它给我们
22、带来的方便我们都心怀感激，这一点我们得感谢Percy Spencer。这位用他的名字命名的专利达120项的发明家，在做雷达实验时，发现口袋里一块巧克力融化了，从而发现了微波的方法。有一点是毫无疑问的，无论是靠碰运气还是刻意努力的结果，如果没有这些先锋们在科技上的突破，我们今天所了解的世界就会是一个完全不同的地方。助读讲解that引导定语从句，修饰oven。as we know it today是as引导的方式状语从句；would have been在此处是虚拟语气，前面由without短语引出含蓄虚拟句。第一步速读了解文章主题和段落大意速读P2425教材课文，匹配段落大意1Para.1ASom
