放射性元素的发现源自一次意外——1896年，亨利•贝克勒尔在巴黎不慎把一包铀盐忘在抽屉里包着的感光板上。过一些时候以后，当他取出感光板的时候，他吃惊地发现铀盐在上面烧了个印子，犹如感光板曝过了光。铀盐在释放某种射线。
考虑到这项发现的重要性，贝克勒尔干了一件很古怪的事：他把这事儿交给一名研究生来调查。那名研究生就是居里夫人~~~

书本的朗读语音很charming的磁性英音~~~大家可以好好学着模仿哦~~~！！
因为原著为美国人所写,单词采用美式拼法,不抄全文，也不用写序号。答完一空换行继续下一空作答。文中需听写单词或词组用[-No-]表示，句子用[---No---]表示。请边听写边理解文意，根据下面的TIPS训练听写。这样可以提高听力准确度，并为训练听译打下基础哦~~~

TIPS听写训练点：单词拼写，时态，单复数，连读，长难句（请边听边用符号先记下内容，然后自己回头组织语句，最后校对，不要逐字逐句听写）当然啦，还有很多相当地道不错的表达方法可以顺道一起学到!

The 19th century held one last great surprise for chemists. It began in 1896 when Henri Becquerel in Paris carelessly left a packet of uranium salts on a wrapped photographic plate in a drawer. [---1---] The salts were emitting rays of some sort.

Considering the importance of what he had found, Becquerel did a very strange thing: [---2---] Fortunately the student was a recent émigré from Poland named Marie Curie. Working with her new husband, Pierre, Curie found that certain kinds of rocks [-3-], yet without diminishing in size or changing in any detectable way. What she and her husband couldn't know—[---4---]—was that the rocks were converting mass into energy [-5-]. Marie Curie dubbed the effect "radioactivity." In the process of their work, the Curies also found two new elements—polonium, which they named after her native country, and radium. In 1903 the Curies and Becquerel [-6-] the Nobel Prize in physics. ([---7---])



When he took the plate out some time later, he was surprised to discover that the salts had burned an impression in it, just as if the plate had been exposed to light. he turned the matter over to a graduate student for investigation. poured out constant and extraordinary amounts of energy what no one could know until Einstein explained things the following decade in an exceedingly efficient way were jointly awarded Marie Curie would win a second prize, in chemistry, in 1911, the only person to win in both chemistry and physics.
19世纪给了化学家们最后一个重要的惊喜。这件事始于1896年。亨利•贝克勒尔在巴黎不慎把一包铀盐忘在抽屉里包着的感光板上。过一些时候以后，当他取出感光板的时候，他吃惊地发现铀盐在上面烧了个印子，犹如感光板曝过了光。铀盐在释放某种射线。 　　考虑到这项发现的重要性，贝克勒尔干了一件很古怪的事：他把这事儿交给一名研究生来调查。说来运气，这位学生恰好是一位新来的波兰移民，名叫玛丽•居里。居里和她的新丈夫皮埃尔合作，发现有的岩石源源不断地释放出大量能量，而体积又没有变小，也没有发生可以测到的变化。她和她的丈夫不可能知道的是--下个世纪爱因斯坦作出解释之前谁也不可能知道的是--岩石在极其有效地把质量转变成能量。玛丽•居里把它称之为"放射作用"。在合作过程中，居里夫妇还发现两种新的元素--钋和铀。钋以她的祖国波兰命名。1903年，居里夫妇和贝克勒尔一起获得了诺贝尔物理学奖。（1911年，玛丽•居里又获得了诺贝尔化学奖；她是既获化学奖又获物理学奖的惟一一人。）
