【万物简史】PART II CH 5敲石头的人们（15）

听力简介：

在这门学科的早期，英国人是最活跃的，因此在地质词语中英国的名称占了绝大部分。但是，随着地质学后来在其他地方的崛起，世界各地的名称渐渐出现。原先，地质史分为4个时期的体系过于简单，因此寿命不太长。

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）

Hint:
quaternary

Because the British were the most active in the early years, British names are [-1-] in the geological lexicon. Devonian is of course from the English county of Devon. Cambrian comes from the Roman name for Wales, while Ordovician and Silurian recall ancient Welsh tribes, the Ordovices and Silures. [---2---] Jurassic [-3-] the Jura Mountains on the [-4-] of France and Switzerland. Permian recalls the former Russian province of Perm in the Ural Mountains. ForCretaceous (from the Latin for "chalk") we are indebted to a Belgian geologist with the perky name of J. J. d'Omalius d'Halloy.

Originally, geological history was divided into four spans of time: [-5-]. The system was too neat to last, and soon geologists were contributing additional divisions while eliminating others. [---6---] Today only tertiary remains as a common designation everywhere, even though it no longer represents a third period of anything.
