With the conclusion of a burst activity , the lactic acid level is high in the body fluids , leaving the large animal vulnerable to attack until the acid is reconverted , via oxidative metabolism , by the liver into glucose , which is then sent (in part) back to the muscles for glycogen resynthesis .(4+)
难句类型：复杂修饰、插入语、专有名词
译文：随着爆发出来的运动的结束，再体液中乳酸含量会变得很高，使得大型动物处于容易受到攻击的状态，直到乳酸通过有氧新陈代谢，被肝脏转化成(convert into)葡萄糖，而葡萄糖接下来又会(部分)传送回肌肉中重新合成糖原 。
解释：本句中修饰成分极多，以分词修饰和介词结构修饰为主，作各种类型的状语。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;分词中又包含了三个状语，其中的两个via oxidative metabolism by the liver又起到了插入语的作用，把be converted into拆成两段。
本句的另外一个特征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根据词头、词根我们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，大家应该背下来;而glycogen这种东西则没办法，只能作一个首字母提炼。但是请记住，GRE和GMAT文章中只要出现了这种专有名词，出题者是一定会在文章中把它在文章中所乃至的词义解释清楚的，所以读者遇到文章中做了解释的专有名词，应该力求把解释看懂。

Hardy’s weakness derived from his apparent inability to control the comings and goings of these divergent impulses and from his unwillingness to cultivate and sustain the energetic and risky ones. (难度3)
难句类型：复杂修饰、省略、抽象词
译文：哈代的缺陷一方面缘起于他的某种明显的无能，无法控制好那结不尽相同的创作冲动的穿梭往来;另一方面缘起于他不愿意去培养和维持那些富于生机活力和风险性强的创作冲动。
解释：介词from的宾语有两个并列的部分，由and所连接，在and之后的第二个from前，省略了前面一样的谓语动词derive。本句之所以难，有两个原因，一是derived from 后面的成分太长，初学者难以一下子看下来;二是作为一篇文科文章，用词抽象，难以迅速理解。
