今天的内容石头也觉得无聊，都是学术名词分类介绍。大家权当消遣，把单词句子练了就行。今天的翻译也不全，石头我查过其他网络译本，没有完整版，估计很学术难理解。请大家谅解~~~~
莱尔在《原理》中使用了新的单位。如今，一般来说，地质时代划分为四大块，叫做"代。这4个代又分为12-20个部分，通常叫做"纪"，有时候也称"系"。其中大多数是大家比较熟悉的：白垩纪、侏罗纪、三叠纪、志留纪等等。

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）

Lyell, in his Principles, introduced additional units known as epochs or series to cover the period since the age of the [-1-], among them Pleistocene ("most recent"), Pliocene ("more recent"), Miocene ("moderately recent"), and the rather endearingly vague Oligocene ("but a little recent"). Lyell originally intended to [-2-] "-synchronous" for his endings, giving us such crunchy designations as Meiosynchronous and Pleiosynchronous. The Reverend William Whewell, an influential man, objected on etymological grounds and suggested instead an "-eous" pattern, [-3-] Meioneous, Pleioneous, and so on. The "-cene" terminations were thus something of a [-4-].

[---5---]: Precambrian, Paleozoic (from the Greek meaning "old life"), Mesozoic ("middle life"), and Cenozoic ("recent life"). [---6---] Most of these are also [-7-]: Cretaceous, Jurassic, Triassic, Silurian, and so on.

莱尔在《原理》中使用了新的单位，叫做"世"或"段"来涵盖恐龙以后的时代，其中有更新世（"最近"）、上新世（"较近"）、中新世（"颇近"）和意思很含糊的渐新世（"有点儿近"）。 　　如今，一般来说，地质时代划分为四大块，叫做"代"：前寒武纪、古生代（源自希腊文，意为"古代生命"）、中生代（"中期生命"）和新生代（"新的生命"）。这4个代又分为12-20个部分，通常叫做"纪"，有时候也称"系"。其中大多数是大家比较熟悉的：白垩纪、侏罗纪、三叠纪、志留纪等等。
