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）

Soon after taking up his position, Davy began to [-1-]new elements one after another—potassium, sodium, magnesium, calcium, strontium, and aluminum or aluminium, [-2-] . The confusion over the aluminum/aluminium spelling arose because of some [-3-] indecisiveness on Davy's part. When he first isolated the element in 1808, he called it alumium. For some reason he thought better of that and changed it to aluminum four years later. [---4---]

He discovered so many elements not so much because he was serially astute as because he developed an ingenious technique of applying electricity to a molten substance—electrolysis, as it is known. Altogether he discovered [-5-] elements, a fifth of the known total of his day. [---6---] He grew so attached to the gas that he drew on it (literally) three or four times a day. Eventually, in 1829, [-7-]



bang out depending on which branch of English you favor uncharacteristic Americans dutifully adopted the new term, but many British users disliked aluminum, pointing out that it disrupted the -ium pattern established by sodium, calcium, and strontium, so they added a vowel and syllable. a dozen Davy might have done far more, but unfortunately as a young man he developed an abiding attachment to the buoyant pleasures of nitrous oxide. it is thought to have killed him.
上任不久，戴维开始宣布发现一种又一种新的元素：钾、钠、锰、钙、锶和铝。 他发现那么多种元素，与其说是因为他搞清了元素的排列，不如说是因为他发明了一项巧妙的技术：把电流通过一种熔融状态的物质--就是现在所谓的电解。他总共发现了12种元素，占他那个时代已知总数的五分之一。戴维本来会作出更大的成绩，但不幸的是，他是个年轻人，渐渐沉迷于一氧化二氮所带来的那种心旷神怡的乐趣。他简直离不开那种气体，一天要吸入三四次．最后，在1829年，据认为就是这种气体断送了他的性命。
