元素周期表抽象而美丽。很多元素在合成过程中只存在瞬间，科学家无法确定其是否存在。但是门捷列夫的发明按规律预留了很多空位，使得新元素一旦发现便能在表上各就各位。没有人知道元素的数目最多会达到多少。但是，可以肯定，凡是找到的元素都可以利索地纳入那张伟大的图表~~~

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!

In Mendeleyev's day just 63 elements were known, but part of his cleverness was to realize that the elements as then known didn't make a complete picture, that many pieces were missing.

对我们大多数人来说，周期表是一件美丽而抽象的东西，而对化学家来说，它顿时使化学变得有条有理，明明白白，怎么说也不会过分。"毫无疑问，化学元素周期表是人类发明出来的最优美、最系统的图表。"罗伯特•E.克雷布斯在《我们地球上的化学元素：历史与应用》一书中写道--实际上，你在每一部化学史里都可以看到类似的评价。
今天，已知的元素有"120种左右"--92种是天然存在的，还有20多种是实验室里制造出来的。实际的数目稍有争议，那些合成的重元素只能存在百万分之几秒，是不是真的测到了，化学家们有时候意见不一。在门捷列夫时代，已知的元素只有63种。之所以说他聪明，在一定程度上是因为他意识到当时已知的还不是全部元素，许多元素还没有发现。他的周期表准确地预言，新的元素一旦发现就可以各就各位。
顺便说一句，没有人知道元素的数目最多会达到多少，虽然原子量超过168的任何东西都被认为是"纯粹的推测"；但是，可以肯定，凡是找到的元素都可以利索地纳入门捷列夫那张伟大的图表。
