霏霏永远爱来来
Albert Einstein Albert Einstein was considered the greatest scientist of the 20th century and one of the greatest of all time. His discoveries and theories have greatly influenced science in many fields. Einstein was born in 1879 in Ulm, a city in Germany. As a boy, he was slow to learn to talk, but later in his childhood he showed great curiosity about nature and ability to solve difficult mathematical problems. After he left school, he went to Switzerland, where he graduated from the university with a degree in mathematics. In 1905, Einstein began to publish a series of papers which shook the whole scientific and intellectual world, and for the theories he established in the papers he won the Nobel Prize for Physics in 1921. Because Einstein was Jewish, when Hitler took over Germany in 1933, he had to leave the country and finally settled in the United States. There he continued his study on the structure of the universe until his death in 1955. Among the several important discoveries Einstein made in his life, the greatest is the creation of his famous Theory of Relativity艾伯特爱因斯坦艾伯特爱因斯坦被视为 20 世纪和最好的之一最伟大科学家整时间。 他的发现和理论在许多领域中已经非常影响科学。 爱因斯坦在 1879 年在 Ulm 出生, 在德国的一个城市。 身为一个男孩，他慢学习说话，但是稍后在他的孩童时期方面，他表示关于自然的棒好奇心和能力解决困难的数学问题。 在他离开了学校之后, 他去达到他从大学以数学的一个学位毕业的瑞士。 在 1905 年，爱因斯坦开始出版摇动了整个的科学和智力的世界的一系列的文件, 和为理论「他在他在 1921 年为物理学嬴得了诺贝尔奖的文件中建立」. 因为爱因斯坦是犹太人的，当希特勒在 1933 年接管了德国的时候，他必须离开国家和最后被定居美国。 在那里他在 1955 年直到他的死亡继续在宇宙的结构方面的他的研究。 在一些重要的发现爱因斯坦之中在他的生活方面制造, 最好的是他的相对论的出名理论的创造

分类: 外语/出国 问题描述: 任何一个,最好是带有感想的急!!~~帮忙啊 解析: 以下是介绍英国伟大的科学家和物理学家史蒂芬.霍金的 NO BOUNDARIES imagine this:you are enty-one years old and a promising graduate student at one of the top universities in the world.One day,your doctor tells you that you have an incurable disease and may not have more than elve months to live.How would you feel?What would you do?Most of us would probably feel very sad and give up our dreams and hopesfor the future.Here is what Sphen Hawking thought:(There did not seem)much point in working on my PhD--I did not expect to survive that long>Yet towyears had gone by and I was ont that much worse.Infact things were going rather well for me and I had got engaged to a very nice girl, Jane Wilde.But in order to get married, I needed a job,and in order to get a job,I needed a PhD. Instead of gining up. Hawking went on with his research,got his PhD and married Jane Nor did he let the disease stop him from living the kind of life he had always dreamt of. He continued his exploration of the universe and travelled around the world to give lectures.In 2002,Hawking visiter China and spoke to university students on Hangzhou and Beijing.As his disease has disabled him,Hawking has to sit in his now-famous whellchair and speak through a puter.He told the students about histheories and thoughts on some of the greatest questions:What is time,how did the universe begin,and what exactly sreblack holes? Hawking became famous in the early 1970s, when he and American Roger Penrose made new discoveries about the Big Bang and blacd goles.Since then ,Hawking has continude to seek answers to questions about the nature of the universe.In 1988,he wrote A Brief History of Time, which quickly became a best-seller. Readers were pleased and surprised to find that a scientist could write about his word in a way that ordinary people could understand. In the bood ,Hawking explains both what it means to be a scientist and how science words .He tells readers how discoveries are made and how they change the world.Science,according to Hawking is often misunderstood:people lften think that science is about "true"facts that never change. Scientists,on the other hand, hawking writes, know that their job is never finished and that even the best theory can turn out to be wrong . A scientific theory is the result of the scientific method. Scientists look at the world and try to describe and explain what they see .First. they carefully observe what they are interested in .To explain what they gave seen,they build a theory about the way in which things gappen and the causes and effects.Finally, the scientists test the theory to see if it matches what they gave seen and if it can predict future enents. If what they are observing can be tested in a practical way ,scientist will use experiments.But if, lide Hawking, they are studying something that is too large or too diffcult to observe directly, they will use a model to test the theory. People who listen to Hawking 's lectures sometimes find it difficult to understand him ,because his thoughts and ideas often seem as large as the universe he is trying to describe.The speech puter is not the problem.In fact, piople who hear it often say it sounds just likea guman voice.Hawking is happy with it ,too."The only trouble ,"says Hawking, who is British,"is that it gives me an American accent." PS:打得有点急,可能有的词会打错,有不通顺的地方要仔细思考,这是高二年的课文,难度适中,生词不明白要勤查词典,衷心希望你能学好英语! 牛顿 Isaac Newton was born on December 25, 1642 (by the Julian calendar then in use; or January 4, 1643 by the current Gregorian calendar) in Woolsthorpe, near Grantham in Lincolnshire, England. He was born the same year Galileo died. Newton is clearly the most influential scientist who ever lived. His acplishments in mathematics, optics, and physics laid the foundations for modern science and revolutionized the world. Newton was educated at Trinity College, Cambridge where he lived from 1661 to 1696. During this period he produced the bulk of his work on mathematics. In 1696 he was appointed Master of the Royal Mint, and moved to London, where he resided until his death. As mathematician, Newton invented integral calculus, and jointly with Leibnitz, differential calculus. He also calculated a formula for finding the velocity of sound in a gas which was later corrected by Laplace. Newton made a huge impact on theoretical astronomy. He defined the laws of motion and universal gravitation which he used to predict precisely the motions of stars, and the plas around the sun. Using his discoveries in optics Newton constructed the first reflecting telescope. Newton found science a hodgepodge of isolated facts and laws, capable of describing some phenomena, and predicting only a few. He left it with a unified system of laws, that could be applied to an enormous range of physical phenomena, and used to make exact predications. Newton published his works in o books, namely "Opticks" and "Principia." Newton died in London on March 20, 1727 and was buried in Westminster Abbey, the first scientist to be accorded this honor. A review of an encyclopedia of science will reveal at least o to three times more references to Newton than any other individual scientist. A 18th century poem written about Sir Isaac Newton states it best: “Nature and Nature's laws lay hid in night: God said, Let Newton be! and all was light. —Alexander Pope

范文：
Ernest Rutherford was a British physicist known as the father of nuclear physics. He is considered by academics to be the greatest experimental physicist since Michael Faraday.
欧内斯特·卢瑟福，英国著名物理学家，知名为原子核物理学之父。学术界公认他为继迈克尔·法拉第之后最伟大的实验物理学家。
Rutherford first proposed the concept of a radioactive half-life, demonstrating that radioactivity involves transmutation from one element to another.
卢瑟福首先提出放射性半衰期的概念，证实放射性涉及从一种元素到另一种元素的嬗变。
He then classified the radioactive substances by penetration into alpha and beta rays and proved that the former were helium ions. He won the 1908 Nobel Prize in Chemistry "for his studies of elemental disintegration and radiochemistry".
他又将放射性物质按照贯穿能力分类为α射线与β射线，并且证实前者就是氦离子。因为“对元素蜕变以及放射化学的研究”，他荣获1908年诺贝尔化学奖。
