难句种类：复杂修饰、插入语、专有名词
译文：伴随爆发出来的运动的结束，再体液中乳酸含量会变得非常高，使得大型动物处于容易遭到攻击的状况，直到乳酸通过有氧新陈代谢，被肝脏转化成（convert into）葡萄糖，而葡萄糖下面又会（部分）传送回肌肉中重新合成糖原 。
讲解：本句中修饰成分极多，以分词修饰和介词结构修饰为主，作各类型型的状语。前面的状语和主句还好理解，从leaving开始句子变难；leaving引导的直到句末的结构来做整个句子的状语；分词中又包括了三个状语，其中的两个via oxidative metabolism by the liver又起到了插入语有哪些用途，把be converted into拆成两段。
本句的另外一个特点是其中充斥着专有名词。其中的body fluids, oxidative和resynthesis通过字面的意思或者依据词头、词根大家还是应该猜出其意思的，lactic acid, metabolism 和muscle这三个词在生物类文章中极其常用，大伙应该背下来；而glycogen这种东西则无法，只能作一个首字母提炼。但请记住，GRE和 GMAT文章中只须出现了这种专有名词，出题者是必然会在文章中把它在文章中所乃至的词义讲解了解的，所以读者遇见文章中做知道释的专有名词，应该力求把讲解了解。

讲解：本句中插入语的用法revealed most clearly on plantations where sale wa infrequent, 后半个分句中的主语that slaves' preference与系动词was离得太远，导致阅读的困难。

8. Gutman argues convincingly that the stability of the Black family encouragedthe transmission of-and so was crucial in sustaining-the Black heritage of folklore，music，and religious expression from one generation to another，a heritage that slaves were continually fashioning out of their African and American experiences. （4）

译文：古特曼人让人信服地论辨道，黑人家庭的稳定能够帮助包含民间传闻、音乐、及宗教表达在内的黑人文化遗产一代一代传递下去，因而在保持文化遗产方面也起着至关要紧有哪些用途，而对于这种文化遗产，黑奴们不断地从其非洲和美洲的历程中予以丰富进步。
讲解：由that引导的宾语从句中，encouraged的宾语the transmission of the Black heritage被同时表示并列和转折的and so 分开，给读者导致了阅读上和理解上的困难。最后一个逗号后面的部分是修饰前面的black heritage的同位语。
