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。
